Hi Mark

Have you done much with smaller BW turbos, i am at a similar point currently running a t34 .48 & 55 blacks @ 390bhp i have a few more supporting mods to do drive train and brakes then i wanted to up the power a little more, im not looking for big numbers some where round the mid 400's.

TBH i will be sticking with the webber management and 2wd manifold i dont have a lot of clearence in my car so i think it would require a custom manifold if changed, do the BW's need the modern management and manifold to make them worth wild.
