I have a first gen rx7 with twin non-sequential TO4 turbos, Haltech F9 ECU, extend port,Holley Annihilator ignition, 3"Mandrel exhaust, High flow muffler, turbosmart dual stage boost controller, Toyota Supra 5 speed box, 3" 5mm wall thickness drive shaft.

NA it produced 170 RWHP and ran a 14.02.

I have since done all the mods and am planning to run between 18 to 24 PSI boost. I will be dynoing it in the next few weeks, so i'll see how it goes.

I also have a 50-400Hp NOS kit to fit to it, but i'll only give it about 100 shot if needed.

I'm not interested in predicting what HP it will or should make so i will post the results when they are available.

 

A FB Turbo with NOS. I can Imagine It now....You are probably the first of It's kind that I have heard. Wait a minute, you are. Keep us posted.

 

I'm sure theres been other FB turbos with N20, especially since their were stock FB turbos. Now twin to4 turbos, and with N2O definitely the first one I've ever heard of and prolly IS the first one.
