  Project Lotus Elise Part 1 - A proper introduction to the marque. 

By Wes Dumalski

ACBC

These letters adorn the hood of every Lotus offered for sale worldwide.... They are an homage to Anthony Colin Bruce Chapman, the British Designer who founded Lotus Cars. Often times when people talk about car design they rarely speak of company ideology as designs of modern day production cars tend to include a series of compromises in performance for the sake of civility and creature comforts. The lack thereof is precisely what drew us to the Lotus marque.  Quite simply the original founder's innovative and influential designs in the motor sports world are still in place on every car Lotus produces.

Enter Project Elise. 

The current Elise platform was introduced  overseas in 1996 and was intended to fulfill the brand's ideals without compromise. With its extruded aluminum chassis, super light weight, mid engine rear wheel drive layout and world class suspension design it would serve to help reform the brand from a financial perspective and prove to be the building block for their modern day success. Overseas they offer different motor options than what we have here in the US from the base 1.8L 1ZZ Toyota motor all the way up to the supercharged 2ZZ 1.8L Toyota built and Yamaha designed motor.

 

The current U.S. version of the Elise is designated as the S2 111R (federal) platform and was first offered for sale in early 2004 as a 2005 model. The car weighs in at approximately 1,987 lbs. depending on packages. The chassis is comprised of extruded aluminum pieces that are bonded together with a proprietary adhesive. Yes folks the damn thing is glued together. The result is a chassis that is extremely light weight and very rigid. 

Notice the removal of the passenger side trim pieces? Here you can see a portion of the chassis structure as well as how the entire car is built AROUND the chassis. You don't really sit in the Lotus Elise you kinda wear it... Sizing comes in Xtra Small through Smedium....

Despite the fact that the Elise features a removable top the body panels are not structural in the same way as a unibody car. This means you can get the top off experience without any sacrifice in chassis stiffness or suspension performance degradation. Just how stiff is the chassis? 

Yes we were surprised by this.... This was an attempt to use the front passenger side jack point to raise up  both passenger side tires... FAILED AT THAT however we discovered a quick way to do front tire removal...

 

 

With the trim removed you can see how the seat belts mount directly to the roll bar for both the device itself and the shoulder belt anchor. 

In addition to the very rigid chassis the Elise also features a roll bar that is triangulated to the rear of the chassis. Additionally the seat belts mount to the factory roll bar. While this is no substitute for a real roll cage it certainly is a step above the typical roll hoops offered in other targa top and convertible cars and offers superior rollover protection for track day events.

I've been reading this site for quite some time but this is the post that finally made me register.

if you start looking for more power, i suggest you start looking at the 2gr-fe 3.5L V6 that can fit in that chassis with the E series Toyota transmission.

with a good intake and exhaust the motor puts just shy of 300hp to the ground with the stock ecu.

Wes,

I did the 2gr-fe swap in a 2nd gen MR2. i used to manufacture swap headers and a swap kit for them so i'm a bit biased. if you need any help with the swap just ask. i've dealt with these engines quite a bit.

in the MR2 it drops 100lbs from the rear. i think it adds a bit of weight to the elise, but not enough to matter since you're doubling the HP.

contact Matt at monkeywrench for weights on the elise chassis, he can probably answer your question. here's his dyno sheets: http://www.monkeywrenchracing.com/extra_info_pages.php?pages_id=5

the other alternative that is much lighter is the 2ar-fe. with proper intake and exhaust it puts about 200hp to the ground and it's been proven with a turbo to 330hp to the ground. i've also swapped one of these in an MKI MR2 if you have questions about it (and it's 6 speed EB61 transmission)

there's just no replacement for new technology and more displacement. the zz series are a bit aging and light on displacement.

Marc
# Marc
Tuesday, September 20, 2011 6:57 AM
a quick search says the 2zz weighs 250lbs. and the 2gr weighs 360lbs so it would add about 110lbs. but figure the difference is smaller once you figure the weight of the turbo or supercharger to get the 2zz to that power level. plus you can shed some weight from the stock exhaust to make up more of the difference.


also, the 2ar is 320lbs

My dream Lotus car:
Exige Chassis
Hayabusa v8 from Hartley 3.7 liters 400 hp, 10,000 rpm redline and 200 lbs for engine weight.
Whatever six speed I need to make it work.
And move the seat to the middle so I can pretend I'm in a McLaren F1.

Marc,
The weight difference seems to great to me with those swaps. It accounts for roughly 5.54% of the cars original weight and would impact weight distribution and handling characteristics greatly. Despite the gain in HP and straight line speed our goal with any swap of forced induction setup needs to result in a change of less than 1% to the weight distribution.

We will be focusing on the weak points first along with suspension and brakes. We will work on HP from there!

Keep the comments and insight flowing!

What's funny is monkey wrench is only 2 miles from my house. I never knew what they were and i drive past them almost every day since the new traffic circle is being installed at pontiac trail and M-5. I'll have to stop by one of these day to take a look at what they have.

wes, I think you're going to be very hard pressed to keep to that 1%.

if you're nearby (fort wayne, IN) i can take you for a spin in my 2gr and 2ar powered cars so you can feel the torque. it's quite impressive and would really let you get out of a corner like no other.

simple things like a lighter battery and a lighter exhaust would really offset quite a bit of that weight gain.

but either way, I'll drop the 2gr talk from here unless you ask for more of it.

the hartley v8 is certainly a very exciting option that would fit in there also but it's about $30k and i'm not sure what your budget is. it would actually be a significant weight reduction.

Wes Dumalski
# Wes Dumalski
Tuesday, September 20, 2011 9:02 AM
^ I completely agree on the 1%. But we will stick to our main focus and see what compromises we have along the way and then simply justify them :)

No need to drop the talk at all. WHile at this point it does not SEEM like a first choice I am not opposed to hearing about any and all options.

Hartley V8 is someone else's pipe dream, it will not make it's way in to this project. Not to take away from it, it is simply not a good fit for our goals.

@Marc: Luckily the Elise already has a good aftermarket supporting for its OEM engine. Hopefully the MotoIQ guys have already looked into BOE Fabrication, and specifically their supercharger kits. I know from autocross that the SCCA National Solo XP Champion uses their supercharger and has won XP 4 years running. I also know some track rats who have had really good luck with the supercharger. Apparently the 2ZZ when done right can hold some boost! Can't wait to see more of this car!
Marc
# Marc
Tuesday, September 20, 2011 9:22 AM
yeah, i've been down this avenue myself with MR2s. they use the same engines.

i looked up the difference between the elise and the elise SC and i was surprised to find the difference was 110lbs. i could not find the weight distribution of that but it's very likely all in the rear end.

so that would provide a very good starting point for spring rates and sway bar sizes to rebalance the car with the 2gr-fe engine back there.

at the end of the day most people develop with the stock engine because they can't swap anything. but depending on your power goals (which weren't stated in the article) you're often better starting with more displacement than overstressing the stock motor.

of course, i have some stupid ideas sometimes. so don't blindly listen to me: http://images.thetruthaboutcars.com/2011/04/LMI11S-BS-20-446x350.jpg (that's a WWII 540cubic inch radial airplane engine in an MKII MR2 ... fuel injected with megasquirt for good measure). http://images.thetruthaboutcars.com/2011/04/LMI11S-BS-17-446x350.jpg

something worth looking at is this chart i made for the MR2 guys of many of the toyota engines: http://frankensteinmotorworks.com/PerformanceCurves/HP%20Torque%20Curve3.jpg

In the years leading up to the fruition of this project we have been researching and reading at what people have done. We are familiar and have spoken with BOE. Fred from BWR, as well as Aaron from Radium regarding forced induction setups. Once we determine our HP goals and the route we want to take we will have a better idea of how best to achieve that goal.

Turbo or NA swap is very appealing right now, but first we are focusing on items to make the car track ready.

From a quick look at that site, swapping in the 2GR would mean losing air conditioning. Since Wes only uses this car in the summer, lives in the mid-west, and can't handle anything above 70*, I don't think he'll part with AC.

yes, because if Matt did not do it, it must mean it's impossible to do. what the heck?

let's assume for a second that the stock A/C location isn't available due to frame rail interference (which i doubt is true). you still have the location where the power steering pump is available.

most people won't make custom lines for the A/C. it's just easier to strip it and they say it can't be swapped.

though, to stay on topic. i wonder if you could shed some weight on the car and gain better weight balance by doing something like this: http://masterflux.com/products/sierra/?pid=23

Ain't it the truth!

With the Humidity and heat here in Mississippi it's not optional.

jere - This is not a kit car that you build. Not sure if you were thinking that based on Mike's comment. it is a production car and this is simply documenting the stock Lotus Elise.

Marc and PK- AC will be required regardless of swap. Not afraid of custom anything so if one of those motor's proves to be THE BEST option it will not scare me off. QUite simply though, the K series is HARD to ignore!

@ Marc: No need to get your panties twisted up. My thoughts on AC issues were because of clearance issues, not because the lines were incompatible. Looking at the pictures, it looks like the frame rail is millimeters off of the engine, and there isn't much room up top of in front of the engine. I'm sure you could make it work somehow, but I don't think a full-tilt custom motor swap is within the scope of this project. I could be wrong.

@ Wes: Yep. I know you suffer from Sweaty White Guy Syndrome (SWGS).

And yep, bolt-ons with a K20 results in over 240whp. Amazing engine. Plus, a car like this needs an engine with some revs and screams. K-series has both in spades.

I was looking at the Elise and Exige when I actually thought, for a second, that I could fit in one. When my hopes and reality met, I lost out! But my research did show a LOT on the K-swap, which is where I would've headed. Most guys seemed to spend too much on the 2zz and still not end up being happy :(
Wes Dumalski
# Wes Dumalski
Tuesday, September 20, 2011 2:22 PM
In all honesty I have to agree that I have been researching the HELL out of a K swap. While we are not yet 100% committed to anything in that area yet, the thought of a K24/20 revving to 9,000 rpm's in the Elise makes me giddy. Having owned an S2000 and revving the F20C to 9K on a regular basis it is a feeling I miss.

If not a properly sized turbo on the 2ZZ will make a reliable 300WHP and that is very appealing also.

How is the transaxle on those cars, durability-wise?

BTW, how big is too big for these cars? Never even sat in one, but they're awful small. I'm a 60% guy (5'11", 185lbs), so not huge, but I remember Carlos (SoCal SERCA) saying it was tight in there, and he's somewhere around 5'7" and 150lbs...

Great Project car Wes. Looking forward to your update.
I do not understand why the hell people knock on the 2ZZ so bad ! Is it better than the K20a ? Well, let's see. The K20a has a TON of aftermarket support, the 2ZZ none. Honda's engines work extremely well with Hondata.
Toyota engines have no EMS support.
I personally would stick with the stock block, call the guys at wrench monkey, get a stroker kit with high comp. pistons and some ITB's.
It's not always about power. The chassis dynamic on the Elise/ Exige are great weapon, swapping engine greatly affect weight balance (and as Wes pointed out, since the Elise is such a lightweight car, every little mods affect the handling department).
To keep it simple I would stick with the OE powerplan.

Dual A-arms on all 4 corners, lightweight, revvy engine,doesn't get any better than that.

K20 swap is the way to go, lots of support for it as quite a few people have done it and the performance gain is quite worth it. Only reason Lotus couldn't go with it was because they couldn't get licencing from Honda.
Surprised Eric hasn't been by to slam the Toyota engine for being soulless :)

You absolutely need to get wider fronts , tonnes of understeer was built into the touring S2s over the S1s to make the car more approachable. Funnily enough the move from 195s to 175 was only done for you Americans so they could sell the Elise over there. Steering is unbelievably sensitive to geo adjustments too.

I've always had a slight issue with the suspension, never seemed as though it had enough anti-dive built into its geo.
Most common way to address is by changing front springs and dampers and second most common is to send more brake bias to the rears via changed calipers or brake pads, The stock pads are mediocre.

Thoroughly recommend Nitrons for springs/dampers.

Awesome but whats wrong with 2zz-ge its a perfect engine for the Elise IMHO.
you can boost it safely, which I did on my 2zz-ge powered Toyota Matrix. only pushing 10lb of boost on stock engine with GT2860RS turbo and Hydra EMS standalone and making 270whp and 196trq as my daily driver.

check out this post of Ronin making close to 700whp in his compound charged exige

I've been daily driving my boosted 2zz for 20K miles with no issues and this is on the stock engine and only 1bar of boost. build the engine with stronger internals and it can take 30+lb of boost easily
Well maybe you guys looking for more torque but I think 2zz-ge likes to scream past 8K rpm.

@Kortik, the 2zz-ge is a pretty decent engine, but the K20 is superior. A K20 will make 240whp with bolt-ons on pump gas. Built K20/24s for drag racing will make 300whp NA on race gas. A K20 on boost is just insane.
Kortik
# Kortik
Tuesday, September 20, 2011 10:21 PM
of course k20/k24 is probably superior but 2zz-ge is only 1.8L of displacement compared to K20 2.0L isn't? Yamaha head tells you that cylinder head flows really good. Everyone just does not see a potential of 2zz-ge it maybe getting old but only now people pay attention to what can be achieved with 1.8L 2zz engine.

I think we are getting of topic. I dont know I just like 2zz too much LOL.

PS. I think 2zz meant to compete with B series Honda engines if I am correct.

There is nothing WRONG with the 2ZZ engine in that it functions and powers the car decently. But if that is all we are after then we would not be here would we? K series is a killer motor that provides huge potential and certainly warrants consideration for a swap.

The 2ZZ is getting support from Cosworth and that certainly has me interested.

Lets talk suspension for the Elise. People always seem to mention Nitron. I have seen them and also been in an Elise on track with them. They seem like a decent damper. Ohlins also makes dampers for the Elise. Thought's?

Wes, this seems like a great project in one of my favourite cars, can't wait to read the following chapters.

Just don't forget about that weight distribution and getting it too heavy with an engine swap. Pure power wasn't what the folks at Lotus had in mind, but driveability.
That said, it makes sense to start working on the suspension first.
Hope you enjoy your car as much as I'm sure we will, by reading the next articles.

Wes - I believe KW is one of the few who offer a limetime warranty! I'm just satin people :) I know Eric had mentioned Cosworth manufacturing some Lotus parts, so I like your approach of doing everything else before deciding your engine options.

For the worriers about the possible K-swap, don't forget, Lotus partnered with Toyota for many reasons, BUT a big one was lack of partners for bringing an American EPA/CARB approved motor stateside. I thought one of the Euro versions had a Rover K-series(Wikipedia confirmed) until they wanted to go stateside.
Wes Dumalski
# Wes Dumalski
Wednesday, September 21, 2011 8:48 AM
@ Marillionado
The comments section has blown up but I posted your same concern. Balance! Our goal will be to not mess with weight bias by more than 1%. That is the goal at this point and while it may be lofty, we will NOT allow anything that takes away from the original character of the car and the design that Lotus intended. Our last paragraph of the article is something we intend to adhere to!

@ Der Bruce
KW currently makes a variant 2 that is different from all of their other Variant setups. Rather than using their INOX stainless they specifically developed the body out of aluminum for the Lotus application. I like KW's approach to development and respect them as a company which is why I am drawn to them. While many people use the Nitron and Ohlin's because they already exist, we will research the options best suited to meet our goals even if it means departing from the "norm".

@ Daewoo
Factory SC is overshadowed by other aftermarket SC setups that better fit the Elise and make more power.

@Jeffball610
4G63 is a good motor but there are better options that weigh less and have more modern technology. I do not see this as something that should be considered on this project unless someone just "had" to do it for the sake of doing it.

As of this point Turbocharging the factory lump or a K swap are the top considerations. Again this will be later down the road after other upgrades.

Hmm my post got deleted. If you go the turbo route, is anti-lag part of the equation? The motivation is a more linear power response.

Wednesday, September 28, 2011 10:02 AM
^ Brent I remember reading your comment and I have no idea what happened to it. I know that we did a server upgrade and some migration over the weekend so it was NOT deleted intentionally.

Can I ask about your experience with turbocharged engines with modern day turbo's? Have you recently built one or do you own one? I am genuinely interested here...

I am NOT nearly as smart as Khiem (speedracerUT) on the subject but I did build our project 200SX. It was a 1597 cc 4 cylinder that used a .86 housing GT2860RS turbo with the internal gate and no modifications to the turbine housing. In that application the car made 7PSI of boost by 2900 RPM's and full boost (14 psi) by 3900 RPM's. It had a completely flat torque curve for more than 3000 RPM's (4,000 RPM's to 7,300).

With a properly sized turbo and optimized components and tune there is really no need for a true anti-lag setup in my honest opinion.

Regardless I stand by my first question and welcome dialog on the subject.

Rockwood
# Rockwood
Wednesday, September 28, 2011 10:26 AM
I agree. My primary problem with anti-lag is the power isn't as linear to me. With a correctly-sized turbo, especially an internal gate turbo, there's a ramp-up period that can be quite forgiving, and also makes for smoother coast to power transition. With anti-lag, you have abrupt power that comes on NOW.

Does anti-lag have TPS thresholds where it will let you dial back some boost, or is it an all or nothing affair?

It's also hard on turbos, as I recall.

I still think anti-lag has its place more on a heavy racecar. A turbo in a Elise is going to be a handful as it is, if you add digital throttle response, it'll be a washing machine (spin cycle). :)

@ Brent.... I am just a curious reader myself... That said ALS has it's place in rally and other sports. They want INSTANT power in mostly AWD applications. Not necessary for our project and what kind of power band we can achieve with a properly designed turbo setup.

@ Steve.... I agree that a little lack of response is welcome.... What's that stunta quote "lag for traction top end for action" Something like that...

We are currently researching turbocharger's to see what will work the best to get us to roughly 300WHP (with overhead potential) with THE BEST response.

Wes, nice to see you started on the project. I met you and saw your car at the lotus drive to lake geneva this summer. I was sitting at same table at lunch and I have a 2005 yellow elise. I was the guy who had a nikon d90 camera too. I'll be watching your project to see how it progresses.
I'm looking to add a supercharger to my lotus this winter. Leaning towards the blackwatch kit. I like the fact that it is expandable if i want to add more power in the future and now includes the tuning tool, so I don't even need to send in my ecu. I might just start with their 300 hp tvs kit, but i'm a little worried about blowing my clutch.
That fuel rail sample that you had from Radium was a beautifully designed, machined and finished piece. The quality of the entire radium kit must be amazing. Anxious to see what they offer for the engine management system.

^ Nice to see you here Mike. We just did a product announcement for Radium's fuel surge setups and are also doing a feature on them very soon. We will certainly be offering our opinion on their product based on hands on experience with actual product.

That said Thanks for following the project and be sure to keep me posted on your build. Depending on the path our project takes we may be able to do a nice comparison between the different power adding options when we are done!

We are also discussing this project on the forums more in detail here:

Take care!

Great project! Excited to see what you end up with.

In regards to engine swaps, weight gain and weight distribution: don't forget about vertical weight distribution as well. I'm curious if the K series are heavier up top (or lighter) compared to the OEM motor. Definitely another data point to look at as it will play a big "roll" (pun intended) on the handling of the car.
