Gt42

People get far too hung up on hp figures when they haven't even experienced a genuine 500hp engine in their life.

That 570hp Skyline I mentioned was a seriously quick car, It did everything so well and for what I've read on here about the GTX3076 being a rubbish turbo it totally worked on that car, there was still room for more power but you have to factor reliability into these cars and the guy that maps for me does not ever feel the need to run the engines too hard, especially when you consider these are 2wd so can get a bit lively !

I really do believe that unless your willing to build a half decent specced engine you are going to run into issues no matter what turbo you use, big turbos will surge and even more so on a poorly specced engine, a good head job and the right cams go a long way to a engine making the power well.

A few people on here have achieved good results using things like a GT35 which by the sounds of things is the area you want to be in, 600-700hp is achievable from those but you are still talking a lot of money, it all comes down to what your budget is as there is no cheap way of getting big hp. ( and 500+hp is big hp )

I think a well set up engine with about 500-550 will make you poo your pants .

Allso is the car set up for more power ie brakes suspension ect ect .

I my self know how you feel thinking more is best I'm going for around 600 but went out in a car running 450ish and it was a monster round town .

Exactly this

being one of these guys with ~850+ AWHP setups, like Jo said even if this turbo was free AND they paid you a thousand bucks to take it from them, it would not be very good for much BUT a full out drag car (like what i have/run).

really, instead of trying to build a car or motor around a cheap/free part such as a turbo, what you REALLY need to do is decide a use and level that you want and CAN AFFORD, and build towards that end. you will SAVE a lot of money doing so, and not waste money on stuff you dont really need.

just my $0.02 its always free and hardly ever liked

i ran a gt4094 at 25 psi and did 635bhp. i now have a gtx4202r and will make around 950 bhp . unless you have £15000+ sat in your bank or cash under your bed then forget the gt42 as thats the least it will cost. trust me i know . swap your gt42 for a gt35 and it will still make you do a little wee in your pants dont worrie
