i have the crv b20z and a type r head .mmmmmmm sounds nice combo
Rods piston and block gard is comming for the b20.
what do you think should i do sell my itr head ecu and transmission and bild a b20 turbo or keep the head and bild the crvtec turbo
will a crvtec build properly be reliable to rev safely up to 8500 rpm?
i need good oppinion thx

 

If money is not an issue, go all out and do the CRVtec turbo.. otherwise sell the head and use that money to build up the B20 or to buy a good engine management system.

 

It sounds wort it, lol Yeah money will be a factor unless that is just something that you don't have to deal w/.

 

I've been considering this too, is it worth it, or should I just get a Drag 3, and put it on my B18C5?

 

please could you give more info on how to build a b20vtec turbo.. what components you suggest, what work to have done on the block, what turbo kit would you choose, what fuel management, etc.. i'm very interested in getting more info on this topic cant seem to find much on the net.

thanks!

 

9.5:1 pistons/rods in your B18C5 + Drag3kit + engine management system = 1 ****** ****** fast and "reliable" R

**** a B20 you dont need it..

i agree, stick with a b18c5. They also draw awesome hp numbers when turbo'd

 

definitely worth it if you do it right the first time and don't cut corners. you'd be making some wheel spinning torque numbers!

 

Blah! Ill give you my ls turbo for yer b18c5. All about all motor madness w/ that baby hehe.

 

as far as i know..nobody sleeves the b20 blocks (yet). - with that in mind it puts your maximum boost level to around 15psi because of hondas open deck design.

I would go with a b16 or b18 and sleeve/stroke it to 2.0 or 2.1 (if you use the b18) and then you can run 30psi safely. (with the right supporting mods of course)

I wouldnt bother with the b20 personally..waste of time if you wanna go all out. If you want something stock and pretty fast then the b20 might meet your needs.

learn something new everyday. Do you know how big they can bore out the b20? What size piston can they fit in?

so you guys say that crvtec will cost me $$$$$ so what about b20 turbo ,b20 is a monster thorque and will make turbo spool faster maybe in the 2500rpm ,
the b20 has some thicker wall cylender whit a block gard should be safe to boost 20psi or 400 whp???
no one here did a b20 turbo?
dustin or annyone who knows what his talking about

 

i have seen crvtec/turbo making around 350hp @ 12psi. Ditch the vtec head and you might loose say 50hp..but 300hp @ 12psi is nothing to shake a stick at. And with the large bore it will be a torque monster and spool a pretty big turbo really nice.

Lets say I put in a B20Vtec in my Gsr with my exact set up. Now, I dynoed at 277 whp at 7.35 psi. Now, the b20 displaces 10% than my Gsr. Ive seen at 8psi B20 vtec dyno at 304whp, and the funny thing is that is exactly 10%more whp than my car. We are finding out now that there really is "no replacement for displacemet"

I am still getting my CRVTEC setup dialed in but dynoed at 3-4 p.s.i it netted 224 w.h.p.
I believe it should do over 300 easily with gobs of torque.

 

awesome power!!

I think that the vtec head will make more then 50 whp then stock head

 

I think Liam was saying If you ditch the Vtec head then you might loose 50hp. I think thats what he meant, right?

what exactly is needed to mate a b20 block to a say an ITR head? lets say you have a b20 block sitting at home along with an ITR head.. just a new headgasket and slap it on? JE makes pistsons for b20 and eagle rods are available for it too right? basically the question is how difficult is it to put a b20 together if you have all of your parts..

 

I don't know exactly what is required but i'm pretty sure that it takes more than just a new headgasket. From what i've heard, some drilling is required.

i love torque mike so i would go with the B20z! Good torque like you said. This is what im getting with my nitrous set up.

 

hey xxplosif wazzup!!!!
im working on my new project this winter stay tuned
is your nos comming for sping?
good luck whit your project

 

How much do B20 blocks go for. Cause it seems more worth it to get a B18a/b block and bring it to GEM(godzilla sleeves are 750) and it will be same bore or bigger than a b20 but also much stronger.
