Hey everyone im new to the forums ive done alotta reading here though and now i have a couple ????'s on my buildup. So heres the setup its a 94 jdm complete swap. I already have jdm itr oversized pistons and rings skunk2 stage one cams, skunk2 cam gears, itr intake valve springs, dc jdm header exedy clutch and cluthmasters flywheel and a type r throttle body. I have a couple things that im unsure of 1. is should i go with the skunk2 intake manifold? Is the stock gsr gonna kill my top end? 2. I know the gsr intake springs are the same as the itr exhaust springs should i move them to the exhaust side or just buy new ones also the same thing on the retainers i believe gsr retainers are the same as itr retainers should i get new ones or just use the ones already in the motor 3. should i go with a mugen or spoon headgasket for a little higher compression of just shick with oem honda. Are they reliable as the oem headgasket? Sorry for the long *** post. Thanks for all replies. Oh yeah this is going in a 95' civic coupe.
