I have yet to see a ct-e supercharged 8th gen with nitrous on the forum so I figured I would post mine up. Car is running the stock K20z3 that came with the car. I pulled it out back in the summer of 2015 to build the bottom and top end of the car. Transmission is currently stock, I had initially upgraded the stock trans with hardened sleeves and snychrotech synchronizes, I ended up blowing 2nd gear. It currently is running a stock, Z3 trans from a 2010 with 50,000 miles. When I initially built the car, the plan was to see how far the car would go with the ct-e kit. It has been fun, the last e-dyno I did was 390+ hp. I recently got the itch for more power and decided to throw a nitrous kit on it. When I first built and tuned the car with Vitviper, I was running DW 1300 cc injectors. They were horrible, so I recently upgraded to the DW EV14 1200's and am in the middle of a retune. Once we finish the retune, I will be tuning the nitrous again. I still have not settled on what jets I will use, part of me wants to go 500 plus, but the sensible side has wondering if it is worth another transmission. Let me know what you guys think!

Yes, I did take it to the track last year, we went to IFO. I sat in line like all day at test and tune and got to do one run. I ended up jumping the light so I got no time slip :-( I do plan to get it back out. I am currently working on two tunes right now, a cal with and without nitrous. I have raced a bunch of cars around my area though.. down, south of the border or course. Car is a lot of fun, can't wait to feel this nitrous, gonna be a whole new beast. Just a little worried about the transmission. They are super weak considering how little torque our cars make, even when boosted.
