I'm soon to get a TSI extreme kit for my civic and found quite a few interesting other things TSI makes for our 7thgens. I know our d17a2's (Ex's) have a higher compression than Lx. TSI makes forged pistons for d17a, which i'm thinking is for the Lx cuz the compression is 8.5:1. I'm planning on building up my d17 once i get boosted cuz i've beat up on it rather well and i'm just trying to insure it won't blow with boost. So if these pistions are for lx, WHAT IF........i swapped them out with my stock high compression EX pistons to lower my compression ratio so i'll respond better to boost!?

low compression pistons don't respond as well to boost. the point of low compression pistons is to run MORE boost ;P

oooooooooohhhh, okay, i see. Well, yeah, cool deal. If i re-build my engine i'll be able to run more boost, so yay. Would these pistons be okay to run with an ex head since they're made for lx?

as far as I know, an ex and lx have the same block minus the pistons ... so it would probably work

make sure to get some aftermarket head studs too ... helps against blowing head gaskets

For the same price of the T25bb kit there, you can get a T28bb kit at needboost.com streetlevelperformance sportcompactonly.com and etc!

all d17 engines parts are compatible with each other...dx parts will fit on ex and vice versa... the blocks are the same just differnet pistons and yes they can be swapped... same thing goes for the head, exhaust and other parts..
