I have been running the S15 turbo for a long time and i'm surprised that more people don't use it. This turbo is awesome. At 15- 18 psi you should be in the mid to high 12 sec. range easily. At 20 psi closer to 11's. Trust me, you will love it. You get boost before 2000 rpm.

Forgot to tell you that i'm using the pulsar manifold with the turbo in the stock location. Some grinding was done but nothing crazy. I had to modify the actuator bracket to make it fit. Warning " this turbo is not friendly with the B13 and B14 trannies" I have broken over 10 trannies so far. It builds good torque

. I have a B15 tranny to put in so I hope my problems are solved. Enjoy.

No. Just regular. Third gear is the weak link. It's better to run second gear out then go into 3rd. If you go into 3rd then punch it with that turbo on high boost it strips third gear like a corn on the cobb. It wouldn't happen every time but it will happen eventually.

I'm putting out around 368 to the wheels but the turbo builds boost so early, by 2500 your at full boost. These trannies do better with turbos that build boost a little later in the RPM range. On 20 psi it got me a high 11 1/4 mile ET spinning the slicks in first an second. Need some bigger slicks.

your seriously making that much power on the S15 turbo, thats redicoulous, cant wait to see what it really does, just put my fuel pressure guage and upped the fuel pressure and it feels soo much better, its still on only 9psi until i get the other injectors. Cant wait.

It seems that there are two versions of the S15 turbo. The spec S and the Spec R. "The Difference between this turbo (talking about the Spec R) and the S15 Spec S Turbo (Nisan_14411-69F00/Garrett_466541-5001) is the Hi Nickel "NiResist" turbine housing and inconel blade materials for extreme heat resistance. One can expect to push a few more horsepower out of this turbo than the Spec S version.
