you talking about the bumper thingy being legal? actually i have no idear ahahahahahah the popo hasnt bothered me yet 

as for the power, i got this manifold from a guy boosting 25lb+ along with 75 shot nitrous.  (he build these manifolds)  he was running off all stock internals (except pistons) and got close to over 500hp when his rods blew out the block. (stock rods can handle ~500hp) So the manifold could support high hp.  even 400hp in a 2300lb car should be a blast 

i plan on boosting 1 bar max until i lower the cr from 9.3 but i dont know i may just run that wit 1.5bar    ive read a lot about turbo charging and pretty much it comes down to tuning no matter what you do.

wow looking sick, can't wait to see what your up to next!!, argh now your making me want to turbo my 3
looking forward for your next update!
