Building an FA20 Race Engine for Michele Abbate: Part 1- Planning the Internals

by Mike Kojima

We have known Michele Abbate ever since she was a college student doing track days with her trusty Mazdaspeed Protege and have followed her career as friends as she has progressed up the ranks from recreational driver to a Scion Sponsored driver in SCCA's GT1 class. 

Up to now, Michele has been running her car with a bone stock FA20 engine at a very low boost street blower drive ratio. Although this is decent power, she needs a lot more to be competitive in one of SCCA's fastest classes for production-based cars.

Nerd Alert! Mazda’s Skyactiv-X Engine

by Khiem Dinh

As we are sure many of you have heard, the little car company that could, Mazda, has announced their Skyactiv-X engine with the technology to run Homogeneous Charge Compression Ignition (HCCI). Two major challenges to make HCCI work: timing of the combustion and smooth transition between HCCI and regular spark ignition. The HCCI combustion process has been researched for decades, but the technology to bring an engine using HCCI to market has been elusive until now.

So how did Mazda do it? We are going to take a few guesses, but as with most technologies, it didn’t happen overnight. In fact, we would say Mazda’s first big step was a few decades ago. The final piece of the puzzle is a technology Mazda has called Spark Controlled Compression Ignition (SPCCI), and we will exclusively get into how that ties into making HCCI work.

Turbo Tech: Calculating Turbocharger Compressor and Turbine Performance Advantage with the New Honeywell Garrett GTX Gen2

by Khiem Dinh

In our Turbo Tech series, we have covered a lot of segments of turbocharger performance. We have looked at various aspects of compressor efficiency and performance, turbocharger mapping, and turbo sizing and matching among other things. This time around, we are going to do some more calculations on the turbine side, calculating pressure ratio and wastegate flow along with estimating power gains from the Honeywell Garrett GTX Gen2 turbos over the first generation GTX. You better get your Excel spreadsheets warmed up.

Building the Naturally Aspirated Honda K Engine Part 3, Assembling the Engine

by Mike Kojima

In the previous two installments of our engine build, you were able to take a look at the parts we will be using to build the bottom end and the cylinder head of our Ariel Atom. Notably, we went with a Dailey Engineering dry-sump system, since the Atom has a lot of aero-enhanced grip, and we want to avoid oil starvation.

MotoIQ Wrench Tip - How to Gap Piston Rings

by Mike Kojima

Setting the gap on your piston rings is an important step to building an engine that performs at its best.  Getting your piston rings to have the optimal seal is perhaps the most critical aspect of good engine building.  Of course you want to spend time assuring that your machine work and cylinder wall finish is correct for the type of rings used but a lot of people neglect blueprinting the ring gap.

Project 5.0 Mustang (The White One) Building the Bottom End

by Mike Kojima

In the last segment covering the engine build on our 5.0 liter Mustang, we addressed the top end with CNC ported heads and camshafts from Ford Motorsports. Now it's time to fortify the engine's bottom end so we can have a screaming high-revving naturally aspirated Coyote engine that is still reliable. 

Our target for this build is to have a safe 8000 rpm redline, wheel horsepower in the high 400 range and run on 91 octane California pump gas with reliability and track car endurance. We feel that this stuff is all pretty easily done.

Building the Naturally Aspirated Honda K Engine!  Part 1

by Mike Kojima

The Honda K series of engines is one of our favorites and one of the top production inline 4 engines ever produced in our opinion.  Last year we built a turbo K24 Z7 for a giveaway by Motovicity.   With the turbo project being put to bed we got another opportunity to build a K motor in the form of a naturally aspirated K24 Z7.

Project G20 Race Car: Building a More Bulletproof SR20DE!

by Mike Kojima

The good old stock SR20DE in our Project G20 Racecar has been doing yeoman duty, reliably lasting for the last few years racing in the MotoIQ Pacific Tuner Car Championship and doing many for-fun track days.  The stock SR20DE in our Project G20 Racecar came from a Japanese engine importer and has never been opened up, other than to add big cams back when we used to run the car in N/A trim.  For the past three years the engine has been turbocharged which has greatly increased the strain it's experienced.

Lessons in Turbo Technology with Garrett!  Lesson 1 - The Compressor Wheel

by Mike Kojima

Recently we were privileged to be able to take a look behind the walls of Garrett Turbochargers' research and development facilities.  We were able to get an insider view of the intensive engineering inside a Garrett Turbo and viewed first hand what differentiates it from your typical aftermarket fare.  We were very impressed by what we saw and we would like to share it with you by breaking some of what a World Class OEM supplier puts into the performance turbos any consumer can buy into easily digestible lessons that we will be presenting to you periodically. Perhaps the key part of any turbo is the compressor wheel.  Let's look at what Garrett does to bring you one of the best compressor wheels on the market.

Fabricating Turbo Headers and Exhaust Systems with Eimer Engineering and Burns Stainless

by Mike Kojima

How do you make a good turbo system even better?  We did it by enlisting the help of Burns Stainless. Our subject car had a turbo LS engine.  Although the car made lots of power, it had issues with lag, a drop in top end power, a ton of weight in the nose that negatively impacted handling and a propensity to burn up everything under the hood.

Extreme Engine Tech, Building a High Boost 2JZ-GTE with Brian Crower and JE Pistons-Part 1

By Mike Kojima

Building a 2JZ-GTE is not new on the pages of MotoIQ.  Pablo Mazlumian documented the building of a pretty healthy 2JZ in his Project Supra chronicles over the past couple years. We like the 2JZ powerplant.  It is a strong, robust powerplant capable of sustaining well over 1000 hp and has been competition proven in everything from time attack to drifting.  It is still quite a viable engine 23 years after it was introduced.

Supercharging the Nissan VQ35DE with Vortech!

by Mike Kojima

The Nissan VQ35DE in all of its variations is one of the best six cylinders on the market, light compact and smooth it has a lot of potential for modification. The VQ35DE and its variants in the VQ family is found in the G35 and 350Z.  Although the VQ is a nice performance engine, in the US market it is only available in naturally aspirated form.  Naturally aspirated limits your power, especially when you are talking about a streetable engine on pump gas. 

In our search for more power we decided to try another direction: supercharging.  For our test mule we used a G35 coupe which already had a lot of the basic bolt ons. To this we applied Vortech's bolt on intercooled VQ35DE kit.  The Vortech kit is a relatively easy bolt on and has the advantage that if installed exactly as is, it is a CARB approved 50 state legal system with an EO number.  This is a huge advantage if you live in California or any area that requires smog testing for registration.

It's All About the Zinc - High Stress Wear Resistance with Penrite Oil!

by Mike Kojima

We get a lot of oils and lubricants to evaluate at the MotoIQ office and for the most part we have had good results with the latest high quality synthetic motorsports oils that come across our desks and into the crankcases of our various race and project cars.  When it comes to quality oils we get pretty uniform results, clean burning, low deposits and good wear of the engine's internal components.

Demystifying the Camshaft: Part 1 - Valve Events

by Jonathan Spiegel

As we all know, the key to making power is to create pressure in the combustion chamber - and to create that pressure at the right time. This pressure works to drive the piston down in the cylinder and cause the crankshaft to rotate. The more air/fuel mixture you can get into the combustion chamber, the greater your potential for creating more pressure, and more power.

Extreme Engine Tech: Building a BMW S52 - Part 2: The Cylinder Head

by Nick Betz

If the engine as a whole is the heart of a car the cylinder head would be all the supporting parts that make the heart pump. Without the opening and closing of certain valves of the heart you can’t get blood to flow into the atriums and out the ventricles. Just like the heart, a cylinder head has multiple valves that need to open and close at specific times to get air in to and exhaust out of the combustion chambers to keep the engine pumping.

Extreme Engine Tech: Building a BMW S52 – Part 1: The Short Block

by Nick Betz

There comes a time in a project build when you just have to throw everything out the window and rewrite your storyboard. Over the years we’ve been bolting on parts to Project E36 323is and not seeing the gains we were looking for. Sure it’s been fun but it’s time to make some real power. We had plans for an M50 manifold swap paired with M3 cams, bigger air meter, headers and throttle body but as the old adage goes, there’s no replacement for displacement, so that’s where our journey has taken us.

Extreme Engine Tech: Technosquare's Monster Naturally Aspirated Toyota 4AG - Part 2

by Mike Kojima

In our last edition of the building of Technosquare's monster Toyota 4AG, we mainly looked at the details of the bottom end.  Now we will finish our tour of the bottom end and delve into the engine's cylinder head which is the heart of any high performance engine.

The 83mm x 83 mm stroker motor gives 1800cc.  The 200 extra cc's makes a huge difference, fortifying the 4AG's notoriously narrow power band. The engine cranks out over 250 crank hp, more than the most highly developed Formula Atlantic engines of yore and 30 more hp than the previous 1600 cc version of this motor. Here it is, re released again for your reading pleasure!

Technosquare Howard Watanabe 4AG Engine Build

Extreme Engine Tech:  Technosquare's Monster Naturally Aspirated Toyota 4AG - Part I

by Mike Kojima

The Toyota 4AG is a historic engine, one that was essential in launching sport compact car culture in the USA.  In 1985 the 4AG first rocked the automotive world.  It was the standard engine in the Toyota Corolla GTS, the famed Hachi Roku AE86.  The AE86 was the last of the RWD Corollas and Toyota made history by equipping it with the revolutionary 4AG engine.  Not to be forgotten, the AW11 MR2 mid engine sports car was also powered by the 4AG.
