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.

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.

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.

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.

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.

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.

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.

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.

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.

Way back when the third and final installment of this build was part of our best of 2010 series. It's still a great article presented here for you to check out one more time. Follow the links, read all three parts and enjoy!
When we last left the Technosquare crew, they had completed the stroker 4AG engine's bottom end and assembled the cylinder head. Now it was time for the engine's final assembly and installation into an AE86 time attack car.
