I swear that every time I get ready to start the car after a big project I am nervous like Mission Control on launch day..... As I turn the key and brace for an explosion, the car cranks a few times and fires right up.  A testament to JWT’s tuning prowess. For the first few days the car was driven around and broken in. We left the boost controller turned off to get used to the cars dynamics and make sure everything was sorted before we started to push our luck. Once we were sure all was well we turned on the boost controller and began tweaking. We wound up with low boost settings of 10 PSI and high boost settings of 14 PSI. We quickly realized that we had a completely different animal on our hands. Gone was the original 1.6 and in its place was the tire shredding motor that could. A motor with a big fat usable torque curve that pulled hard to red line. We also confirmed that at 14 PSI we were maxing out the 240SX MAF at 5.11 volts thanks to the Techtom MDM100. With the car running well we strapped it down on the dyno. to see what numbers we could achieve.  At 14 PSI we pumped out 249 HP and 211 TQ AT THE WHEELS. Please keep in mind that these numbers were achieved with the JWT S1 cams and NOT the turbo cams which have since been installed.

Notice the nice fat torque band? This usable power is the result of a properly thought out turbo setup!

With the initial setup done we already had to plan the next stage. We needed to upgrade our MAF and injectors in order to further push the envelope. Knowing that we were going to shoot for a MAF and fuel setup that could easily support over 300WHP it was time to think about a turbo upgrade as well.

With the course plotted it was time to source the components and contact our resources to help us make these upgrades possible. After some communication with JWT we decided that we would use a Ford Cobra MAF, MSD 50lb injectors and top feed fuel rail, and the GT28RS turbo.

The disco potato and MSD 50 LB injectors are waiting in the wings.

 

Given that the project car is in Wisconsin and JWT is in California, Clark was going to have to use his experience with these components on the SR20 and apply them to our GA16 ecu. Good thing Clark knows more about Nissan programming than anyone else we know…. In the next installment we document the upgraded turbo setup and strap it down to try and break 250 WHP with the stock bottom end.

Be sure to subscribe to the project as we re-hash the past to get to the future. Project 200SX is still pushing the limits!

Very Interesting. I got Nissan Parts that I can contribute to this build. Let me know if you need some NISMO tuners or Tommy Kaira body parts.

What was the final hp and torque ratings from the ga16?

The car made 252 219 at 13 PSI through a factory cat some 8 years ago. Since then we have removed the cat and exhaust with time trial in mind. We had to dyno the car at various boost level's to have NASA classify the car. With the boost controller off (approximately 10.5 PSI) it made 211 WHP. at 12 psi the car made 234 WHP. We have dynoed the car at over 270WHP at a much higher boost level however it is not something we ran for any length of time so we never pawned it off on our readers as reliable.

As it were the car supported over 250WHP for 5 years and through full 30 minute track sessions at 95 degree ambient air temps. It was dead reliable.
