... the standard gearbox and LSD can handle the power, but what I dont get is that youve done all these mods and have no idea or estimate on what kinda power your making? For a good idea its a good idea to dyno it before anything to see what you started at. With just bolt ons though im not quite sure what kinda power you should be making, but 250bhp isnt that hard to get with those motors from what I hear. Anyway goodluck. Also your site alot of it is underconstruction.. soo.. I couildnt really see what youve done.
