Hey people, im thinkin about acquiring a civic in the next 2-3 weeks and wanna swap out the d16 in favor of a frankenstein, i just cant decide between the LS/vtec and the CRVtec. I've been searching around the net and i get mixed reviews, and all i ever hear about is "r/s ratios" how it sucks on the LS/vtec and is almost perfect on the CRVtec, help me people !!!!! Also i plan to boost, so keep that in consideration. thanks!

go with the ls/VTEC the crvtec has weak sleeves i personaly like a b18b with a b1b head but what ever

if i were to go ls/vtec what head would work best, i heard the B16 is the best, any other ideas?

themadhatter

well that all depends how much money you have you could put a b18c5 head on there or maybe a b18c1 but i would find a nice b16 head

the gsr head will never flow as well as the b16 head. my setup is a b18b bloack with a full factiry rebuild and a 99 b16 head. its my daily driver and i ran 14.7 in it with a full interior in my 92 civic ex sedan. should have been faster too, look in my signature

I'm sure thier are advantages, but doesn't anyone think that the tech guys from honda would've gone with whatever head on whatever motor to make power. I'm not trying to start a fight, I run mini, but I've heard more then when it comes to d/b combos. Ya figure if those japs didn't do it, it was probably for the best. They have equipment most of us would kill our mothers for, and probably test all types of ideas.

just boost an ls or crv motor. screw the frankenstein crap that wont make a fraction of the power a good turbo setup will.

I know someone running a boosted B18A1..with a small *** T3 A/R 48/42 he ran a 12.22....good engine management.

MrNiceGuy

you should go with an b20 vtec becuz if your turbocharging it, the b20 block has good low compression which is perfect for turbocharging. the b18a/b18b is also good but the compression is higher which means your chances of a blown motor are greater. having the b20 is best if u would like to boost alot

yes, the b20b motor has lower compression, but the b20z motor has higher comp. either way, the b18a/b would be better. you have to factor in other things, like the sleeves in the b20. it uses a closed deck design, 1 piecec sleeve. They are weaker then the b18a/b sleeves.
