hey i have a 91 integra with a b20b in it was thinking about going vtec maybe a gsr head is going b20 vtec a good idea if so what other than a gsr head would i need?

 

i love me a B20 Vtec you will need a ls vtec kit and a vtec ecu. i think thats it. i would do it.

 

Do it. You will enjoy it. Just finished up my little brothers fulyl built B20 vtec, looking to get 240whp.

 

Im lookin to do the same thing but with a b16 head.


Good luck man.

 

Sounds like a plan. I would go for the B16 head because it flows a little smoother IMO & the IM is designed better than the GSR (Dual runners? why the fuck?) But I heard the GSR ups the compression a little & is more reliable? But just speculation?
But you can also get an after market IM ne ways so either head will work.
I say go ahead & upgrade the pistions & build the head, even w/ GSR cams the shit will roll.
What car is this going into?
I have an EF & the shit is fun as hell. But I would definately recommend adding some suspension, because after 120mph with no sway bars & struts bars shit starts to feel hairy a bit.
But GL w/ ur build sounds fun.

B20/VTEC
The walls on the B20 aren't as strong as the LS so consider that if your going boosted. Also I do believe that the B20's rev limit is a little earlier than the B18, not positive though.
I say build the bottom end for N/A & get some nitrous you'll be happy with that for awhile!

 

Oo 91 TEG sweet deal!

 

hey what all does it take to do a b20 vtec all the parts that i need
