i have a greddy 15g turbo on my 97 civic ex coupe.
where does the efficiency fall off with this size turbo? or...where would i be able to find this information? im thinking about adding pistons/rods/sleeves (i have a machine shop at my disposal) and generally building the block a bit.
i like the fact that this turbo spools very quickly, but was wondering how high the boost could be before it started losing efficiency.
also...anyone know if the greddy 18g turbo bolts up the the 15g manifold and stuff?? finally....how the hell do you spell efficiency?????
