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.

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.

By Justin Banner

If there is one good thing about starting at Auto Club Speedway in March it's this: it ain't so freakin' hot! Well, it wasn't hot anywhere except Autoclub Speedway where the MotoIQ Pacific Tuner Car Championship presented by Motul was kicking off the 2013 Season. Would we see a repeat performance by Edik Stepanyan or would 2012 Champion Michele Abbate pull ahead this time? Could one of our new competitors make a charge?  Find all this out and more as you continue to read on about the first round of the MotoIQ Pacific Tuner Car Championship presented by Motul!

Project Infiniti G20 Racecar: Transmission Upgrades

By Steve Rockwood

It seems that every time we try to do something to make Project G20 faster, we find a faster way to break something.  This time around, we were certain that while the stock Nissan RS5F32V transmission in our G20 was made of sugar glass, that our modest turbo power levels, stock clutch, and not-so-abusive driving habits should make it last through a season.  After three race laps, we were greeted with the all too familiar sound of a fork in a garbage disposal coming from the transmission.  Someday, we'll learn a lesson the easy way.

Project Infiniti G20 Racecar: Even More Power

By Steve Rockwood

In kid's soccer, everyone gets a trophy, regardless of finishing order.  No winners, no losers.  Motorsports, on the other hand, is completely defined by whether you're winning or losing.  Unfortunately, our normally aspirated SR20 was not so mighty when compared to the other MPTCC cars, so we forced some air down its throat in the hopes of finally getting some hardware.

Dynomax VT Muffler Test! Does Quiet Mean Slow?

Dynomax VT Muffler Dyno Test!  Does Quiet Mean Slow?

By Mike Kojima

We had been bolting stuff onto our web guy Frank’s Infiniti G35 sedan, including a really cool prototype exhaust system from Berk Technology.  All this did was cause Frank to complain about how loud the car was.  Did we even know this guy anymore?  Anyways, to appease Frank who also happens to be the best web guy we know by far, we had to do something about the noise.

K&N’s Super Unlimited Infiniti G35 Circuit Battle Slayer

K&N’s Super Unlimited Infiniti G35 Circuit Battle Slayer

by Mike Kojima

We have been witness this year to the sheer power and speed of the K&N Infiniti G35 driven by Paul Brown, which is currently tied for second place in Redline's Pro Track Challenge.  What is unusual about this G35 is that it is a corporate car owned and constructed by K&N as an in house engineering effort.  Usually cars like this are regulated to dressing up the floor at the SEMA show then making rounds at car shows but in K&N’s case it is heartening to see the car out on the track kicking ass and taking names!

Project Infiniti G20 Racecar - Making It Stop, Every Time

By Martin Gonzales & Steve Rockwood

Loud engines, big horsepower, gratuitous tire smoke, and high cornering speeds are why we love and watch motor sports. Most people, when they watch racing on TV, listen for the engines, stare at the gruesome crashes or marvel at the speeds drivers carry through the corners. However, much like the scrappy player on a basketball team that gets all the rebounds and never scores, brakes just don't get the attention they deserve.

Project Infiniti G35 Sedan: The Poor Man's M3

Project Infiniti G35 Sedan: The Poor Man's M3

By Mike Kojima

Not all of the cars in the MotoIQ stable are cutting edge performance machines.  Sometimes we do have to have cars that are practical.  Our current office car is a 2004 Infiniti G35 Sedan.  The G35 is an excellent car for daily driving, it gets reasonable mileage in the low 20 mpg range and has 4 doors and plenty of inside room for taking the staff to lunch or meetings. The automatic transmission for dealing with bumper to bumper daily commuter traffic makes jumping into the G35 to go somewhere a no hassle proposition.

Revenge of the Nerd - Nissan in the sump with diamonds?

By Mike Kojima

When we launched MotoIQ, I wrote another article on this subject but it sorta got buried in our initial rush of article releases and since it never appeared on our front page, it languished with almost no reads deep within our tech section.  I think this subject is too interesting to remain buried so this month I am devoting Nerds to  the subject of Nissan's new oil technology. The new Nissan 370 and the Infiniti G37 with the VQ37VHR engine has been plagued with issues regarding high oil temperatures in severe use since their launch making debate on oil a big topic on internet forums. The conversations on oil temperature issues leads to Nissan's recommendations for Genuine Nissan "ester" based oil and the super expensive oil service.

Accidents, the downers of all motor sport related activities, and reminders that things don't always go as planned.  Though spinning out of control or taking Dukes of Hazard jumps are not part of anyone's dreams of racing glory, it doesn't mean shit has to happen before preparing for the worst..

VQ Crazy

 

Recently all around me have been Nissan VQs. There's the Cosworth Castrol Top Shop engine that I have been coordinating and tuning at Cosworth, then over at XS they are building a Z33 for my buddy Andy who owns Ark Design, so as a I built that engine on my own time, then I have been writing reports at Cosworth on VQ35DE camshafts like a madman, then I have been working on the Cosworth VQ35 long stroke crankshaft, my daily driver Maxima has a VQ30, I've been driving my mom's G35 which has a VQ35, etc. VQs kick ass.

 

The Cosworth Top Shop engine made 4xxbhp (buy the magazines) normally aspirated which impressed me. Th...
