I used a rhb5 on my old y7 and it pull pretty good for a street setup since there's like no lag at all. Pull pretty good at 1bar until the y7 spun a bearing 3 months later. I welded a t3 flange over the existing goofy IHI flange since I could find a IHI t3 housing from a t-bird to swap on. That was my custom y7 t3 exhaust manifold. Only cost me 20 bucks to make it. The rhb5 is quite larger then a b2 and the b5 was ******** small. I'd like to see the b2. lol

 

Now I know everyone (including myself) hates FMU's, i just bought this car for 200 running great.Its just my winter car, i have a LS-T @14psi on turboedit for the summer time, but anyway just for the winter i might run the stock injectors and a 12:1 FMU @ 6-8 psi on the mpfi d15 . Do you think it will be cool? I have a wideband to make sure it doesnt go lean.

 

if you got turboedit, why not just use that to tune it decently and not rely on the FMU?
