    Does the sanctioning body specify homologated parts?

    It is a fully built motor except stock manifold.

    Does the sanctioning body specify turbos are free? If not, the answer is up to them really.

    If you are already making 400 hp you have spent quite a bit of money. So you want more - have you found someone locally with a rotated 35 setup to talk with?

    EDIT: Do you have a link to a map or info on your current turbo?

    nope this is my first time on forums, not sure how others are doing with a rotated 35r (i hope they are making gobs of power), oh and yes no expense was spared the car was originally put together by lachutte performance in canada, and now the car is being retuned (with accesport instead of the ecutek software i originally had) with the new turbo (gt35r) at PRE performance. My brother who drives a evo 9 is telling me i will experience too much turbo lag, but I beg to differ. also was considering meth inj. instead of a e85 tune because e85 isnt really close by to my house. Is meth bad or good for an engines health?

    In an of itself it's not usually the issue. The issue sometimes is that to reach the point where people start using methanol there is already stress on the motor. In any case you are setting up a track car so the worries about meth on the street do not apply.

    PRE have an excellent reputation here, BTW.

    Whether turbo lag is going to be an issue for you has to do with the bends you are taking and the gearing you are using also.

    Yea I have been to a few shops in the area including surgeline and was way more comfortible with PRE follow up and hands on approach to teaching me new things and helping me better understand how stuff works, their knowledge was very impressive! the engine should be able to take around 600hp, Maybe meth is not needed, Because I feel like I have got to a point where how much more money can i possibly put into this thing hahaha or maybe my girlfriend is just getting to me hahaha (nags me all the time about how I spend more time with my car than I do her)

    As SD_GR said, meth isn't bad itself. The issue usually comes from too much stress on the system like he mentioned as well, or from a system failure. Since you run leaner AFRs / increased timing when spraying, if something happens to the system and you stop spraying, things could go wrong.

    With that said, meth is a great at detonation resistance (knock kills motors). You can tune the car so it uses it mainly to resist knock, and gain a small amount of power. Tunes like that, which aren't heavily reliant on the meth, will have a better chance at withstanding a system failure than a tune that's balls-out.

    If you go the route of meth, make sure you have quality gauges (e.g., Defi, Greddy, Omori) to monitor what's going on - boost, EGT, WBO2 (e.g., Innovate Motorsports / AEM), and meth flow at a minimum.

    Since you'll be racing: oil temp, oil pressure, and water temp (even though there's one stock, it's "vague") would be good to have as well.
