Its just not worth it for the price of lower compression forged pistons and an exhuast manifold ALONE would be the price of higher compression pistons and a set of cams and youd get the same horse power as what you would if you boosted it, which would cost alot more once you get all you need. If I were you, I wouldnt turbo it cause its not worth it and it has to be done right. It obvious you dont know a whole lot about turbos cause you asked if it needs a certain exhuast setup. Exhuast is a big major part of how a turbo works, and yes I know theres more to it than that also. Which is jsut the other thing. I know you couldnt install one yourself and youd never find many people at any honda dealer inclined enough to install a trubo cause its alot more than just a turbo, theres intercooler lots of piping vaccumm lines, to prevent spiking youd need a boost controller and a WHOLE lot more. Not trying to put anyone down or anything, but Id just hate to see someone dump 4 grand into a trubo and be out a motor cause it wasnt sleeved or done right.
