They i am looking a getting a B20 CRV block for a good price. anyways i have a 92 GSR with a B16 Turbo right now. but i want the TQ#s. so how well does a B20/VTEC work when boosted? i would have the block sleeved, and the pistons and roads done. then i can make the rest work with parts from the B16. so i should have everything i need. someone was telling me that the b20 crank is not as strong as the b16s. anyways i am just trying to get some info on this setup. i would like it to see from 14psi-18spi. right now i am running 11psi on my b16 with full stock internals as a daily driver. so any info i welcome.
thanks

Danny.

does anyone have any info on this?

 

b20 sleeves tend to crack....u may get lucky though....

 

yes he is right the b20 blocks arent that good for a turbo application unless sleeved . My buddy crack his stock sleeves on 260whp.... 8psi I think it was

 

so if it is sleeved then i should more then ok for that block to see around 16psi. thats with rods and pistons and all that good stuff.

the crank would be more then ok?

 

anyone?

 

if you sleeve the block it will be ok . and i wouldnt worry about the crank . i rum 18psi daily on my built set-up

 

if you sleeve it then its pretty much the same as a LS motor. Sleeve it and put some forged piston and roads in there.

 

so the length of the stroke will not be an issue?

 

no it shouldn't if your worried about high to rev it with my old set-up i took it to 8300 with the one currently being built i'm going to take it to 9500

 

i think the stroke is the same as an ls just the bore is bigger.. i have a jdm b20 with jrsc at 8 lb no problem yet.. stock sleaves..... just tune the hell out of it
