It will kill your power and torque I promise. Your best bet is either a reworked gsr manifold or a ported blox or aebs manifold the casting in these manifolds is rough and needs to be cleaned up to optium flow. The plenum/runner volume in the edlelbrock mani is very agressive and really shouldnt be on a 1.8 na motor. I have a couple ported gsr mani's that I have done that supported 200 whp so if you want one hit me up in pm

well I just built bascily the same setup as you are talking about. ls/vtec with gsr head and weisco pistons it would be 13-1 on a gsr block bust since this is a ls/vtec your exact cr would be 12.45-1 using a ls bottom end. and yes it will def get up and go. in a crx tuned really good you could probably runn 12's I have seen a hatch with a simalar setup and lower cr runn 11.6 freaking halled! well good luck with the build sure you will enjoy it got any more ?s feel free to pm me

For that motor a stock overbore itsnt gonna cut it a billet tb is needed 68-70 mm. An overbore is good for mild builds and if you do everything you say you are its way under sized
