I want to change the head on my b20b.....need some advice on which would be best. Im going to be turbo charging the engine so i hear that going vtec would not be the best way....but some people are telling me that a b18 ls head would be good for it or a gsr head even though that they are vtecs....any advice would be helpfull.

 

get a pr-3 head, off a b16 or a type r

 

Basically right now you have a B18B LS head on the motor. You can covert the engine to VTEC (there is some machining involved and you need to drill, tap and plumb an oil feed line) with any of the VTEC heads. The B18C1 head is a little different and has a smaller combustion chamber (resulting in higher compression with the same pistons) and is debateable but probably one of the most efficent heads. The head of an ITR is just a modified (some porting and a valve job) B16A head. Honda doens't really make a crap head (except the 8-valve Civic CX head I used to have) so any of them are desireable. You don't really need VTEC if your going turbo however. The added lift and duration of a set of VTEC cams is what it is and will make more hp then a non-VTEC but the extra overlap on a VTEC cam isn't as productive on a turbo engine as it is on an NA setup. Long story short, I'd personally rather spend the money on upgrading the bottom end of the engine to withstand more boost (with a turbo, more power is just a crank of the boost controller away if your engine can handle it) than upgrading the head.

 

i agree with building the bottom end.. and if you did happen to have a tec head.. just disable vtec... other then that yea ls is the way to go

 

:eh:

Disable VTEC? How would you do that exactly?

 

VTEC killer cams???

 

i dunno lol.. i've just heard of people doing that..

 

umm to disable vtec would just take unplugging the clip. but why would you do that total waste of vtec head. id say if you boosting b20 you must sleeve the bitch lol b20 have girly cylinder walls. cant hold much boost. for the head go with stock b20 head . just buy some valve springs, valves retainers .. ect. but like most people are stating the bottom end is a must man.. concentrate on that or youll see your self looking for a new block.

 

you could buy the lost motion device from www.raceeng.com this will disable vtec

 

why you would loose power
