boosed b20

[cuzzfolk99]

i have 00 si and iim planning on building a street 350-400 whp turbo motor. i currently have a boosted b16 in it and i was wondeiring how would a b20 shortblock built work with a stock b16a2 head on about 14-15 psi??

The b20 isn't as strong. I don't think the bottom end can handle it, not too sure though.

the bore is 84mm and the stroke is 89 mm, that right there is a problem with boost and the sleeves are thin so I would suggest boosting something else.

low boost and dont over rev it, you should be fine

 

[--<EM1>--]

get a b18 block. with b16 head, get sleeved, rods and pistons plus upgrades valvetrain and you can EASILY hit your goal man.

 

[mitcheg6]

no...either sleeve the B20, or fine an H23 block and put an H22 head, good for turbo.Or ya, just boost the
B16

i think im gonna just get my bock sleeved and rod pistons and let it be.

 

[Steven.]

id boost a stock B20, 7psi, on a great tune, people do it

 

[cuzzfolk99]

i dont think it would be worth the money plus i can get the sale parts for my b16a2 and run about the same withought buying a b20 block

 

[RKSskier]

I wouldnt even sleeve your motor, with pistons and rods and headstuds (hopefully already have them) an otherwise stock b16 can handle alot of power, more than enough for a fwd street car. Just one thought

 

[cuzzfolk99]

so couldl i use a block guard pistons rods gsr cams on the b16 i couls hit 300whp+

 

[Steven.]

id advise aginst block gaurds

 

[cuzzfolk99]

why?

 

[swappedcx]

you will be fine with 300 on stock sleeves.

 

[hybrdthry911]

just get pistons and rods, like other poster said dont get a block guard, they are unnecessary and ive seen no data to show they help at all. detonation kills sleeves, and a block guard isnt gonna do s**t about it.
