Well I guess this would be a good time to give an update to my Gerry Johnson Turbo kit installed on my 91 NSX. There are so many things that we have done to the car that I really don’t know where to start.
Construction: The piping is all very nicely designed and the welds are the best that I have ever seen in my life. The piping is very nice allowing you to still use headers instead of a manifold. The flanges that are bolted from the turbo piping to the headers are all laser cut. The intercooler is mounted in front of the new rear valence, with four 5.2 inch Spal puller fans mounted on the back to assist with air flow through the intercooler which is a custom 7x24 inch core. The turbo is a Garrett T-04 gravity fed back to the oil pan, With a Deltagate II wastegate. We have just installed (last week) a Aquamist 2d water injection system for additional cooling of the intake charge. So far it is pretty impressive it is a new system that learns and programs itself. It measure the injector duty cycle and boost, which allows it to adjust the amount of water that is sprayed into the intake pipe without the pain of building your own tables. I also have the sweet sound of an HKS racing blowoff valve mounted right before the throttle body. I love that swoooosh sound.
Electronics: Boost control is handled by a Blitz SBC-ID meter. With the complimentary Blitz power meter mounted next to it for Hp and speed measurements (somewhat accurate). Engine management is controlled by an Electromotive TEC II system mounted in the trunk. The TEC II gives you the ability to 100 percent tune all aspects of the motor, which is very nice. The turbo timer is also manufactured by Blitz.
Fuel delivery: Gerry installed a Denso racing fuel pump delivering all the fuel via steel braided lines to the fuel rails, With a nice NOS fuel regulator and filter. We also installed 680cc injectors, for my dream of one day scraping enough pennies to get the motor done with the darton sleaves and low compression pistons.
Driving impressions: The car is very amazing to drive and will leave you quite speechless. I find myself making excuse to go places, like intentionally forgetting things at the store so I can go for another ride. I have full boost (8-10 psi) between 2500 and 3500 rpms. I have no turbo lag that I can feel at all. The torque is unbelievable in the lower RPM range. The Vtec is setup to trigger at 4k and feels very nice when it does. I used to drive the car very hard (redline quite often), I now find myself shifting at a very modest 4-5k RPM’s because unless your racing there is no need to take it any higher, There is just so much torque down low. We will be taking the car to the dyno hopefully in the next two weeks for final tuning and I will post the results when we do. If anyone is in the CA area and would like to take it for a ride let me know. I live in northern ca, about 20 minutes from Gerry, but I often go down to the LA area.
Support: I find that Gerry is very easy to get a hold of and has no problem talking to me on the phone for hours answering any questions or helping me understand different things that we have done to the car. We have spent numerous times working on the car until 4 in the morning installing various items. He pays very close attention to detail and is very meticulous of his work. He cut absolutely no corners on any part of the install regardless of how long it took to do it correctly. I would recommend his turbo kit or engine work to anyone. I have had the Turbo kit on the car for almost five months now and it is my daily driver. I have had no problems whatsoever.
I have driven every flavor of forced induction (Gruppe M, Comptech high boost, and BBSC) and owned one of them. I do not think that they really even compare to the GJ Turbo. The Turbo has much more grunt and is almost limitless in what you can do with it, Probably the best option is you can adjust the boost on the fly (0-whatever) and you can adjust the spool rate (0-100%) all from the cockpit via the boost controller. TURBO is definitely the way to go. Period…If you think differently lets go for a ride.
Below is a link to see pictures of my car and turbo kit. Also below is a complete list of modifications done to the car. Keep in mind when viewing the pictures that the exhaust is still not ceramic coated and the intake pipe is not chromed yet. I was getting to impatient to drive it during the install, so I did not want to wait for the pipes to get done. Now it is hard to let it go for a few days to get the pipes coated. I am having too much fun driving it.
