Im kinda back and forth over this issue, I have jdm d15b and Im wanting to up the power a tid bit, say 200 or 220whp.....anyways, I have a zex kit that I could run right now with say a 50 or 75 shot and be decently quick and reliable, I know nitrous pretty well. And then a friend of mine, has a turbo kit that he's offered to sell me with a t28 turbo and has been tuned to 200whp on his car, same motor. He's including everything with it for $1000. I would appreciate some thoughts and opinions on this. Also I can usually only get online when Im at class at night, so forgive me if I dont respond quickly. Thanks.
