I just got of a friend a complete b16a vtec head out of a 89 teg ,is that obd1? .Now im not sure if i should buy a ls teg or a b20 prelude?which would be better ?Im planing on using a vafc and 50-75hp shot of nos not sure which nos setup either as ive never had a car on nos.Also what sort of power gain would i get from the vtec head on which ever car?Thanks for your help

yes,the head was off a jdm teg .Ive done a bit a research and seems like theres alot more to a ls/vtec and money behind then i relized.Ive got the complete head ,arp rod bolts,b16a pistons.Would it just be better to turbo a ls motor than vtec it?What gives the ls/vtec the torque?is it the crank? Just say i got a jdm b16a vtec and fitted a ls crank would this be a power upgrade?Ive got a d16z6 turbo at the moment but i wana try a b-series for my next motor.I can get a eg civic sir front cut for $4000us.And do a swap and keep my eg civic.

just keep the whole b16 and drop the whole bitch in, then spray some NITROUS not NOS

if u put the ls crank in a b16 block you'll put the pistons through the head. the LS and GSR blocks are taller then the b16.

if you have an ls block already, you're not gaining much torque, you gain some hp up top, you're only really gaining torque if you have a b16 and swap out the bottom end for a b18. but what gives it the torque is the 1.8 as opposed to the 1.6 and no, you can't put a b18 crank in a b16. but, you'll be looking to spend about 4-500 bucks in parts besides the head and the block.

I personally like the CRV-TEC setup but thats my own personal take.

As some of the other guys have said, B20 from the preludes are good for nothing pieces of ****. They will not fit the B16 head. You are better off going with the LS bottom or a getting a CRV B20B or B20Z bottom block. Both will give you more torque than a B16 to start off with just because of the larger displacement. But there is more $$$ involved and miscellaneous things you have neglected to look at. A B20 VTEC is a pretty damn expensive swap and build up to say the least...

In the end, its up to you...
