help no one knows in my town

i got a b21 and i was wantin to know if there is a vtec head i could put on it and witch heads would work?

never heard of a b21, what kinda car is it out of??

I've heard rumors/stories of people putting b16 head on a b21, but i have never seen one. From what i understand there is a lot of machine work needed, if it will even work at all.

Jeef: the B21 is from 91 Prelude Si

I heard the b21 doesnt even share the same mounts or anything. Have fun with that. Thats the red headed step child of all b series motors.

I believe there was a guy on the old H-A.net but I don't even know if that site is around anymore.

Its was fucked, and no one believed it was doable but he did it.. Lots of work required though.

No help from me, but it has been done before, and I saw the pics. :p

never heard of a b16 head on one but dosent hurt 2 try
sounds 2 me like its a beefer ls block

I just saw a guy who redrilled the holes in a DSM turbo manifold and use the DSM turbo setup on his B20A5... had to grind away some small casting lines on the tranny and block and slot holes in the manifold, but it bolted on :D

Old shitty car drivers are crafty because we have to be. :p

want to be crafty, buy an amc strait 6, I have did things that would amaze people.

the guy who did that ran this site. www.ludespeed.com and apparently hes gone out of business. he used to sell modified b16 heads and headgaskets for the conversion, but stopped because it was too costly and didnt put out nearly as much power as his turbo kits did.
