I have a b20 block not sleeved, and I have fully ported gsr head, skunk 2 pro 2 cams, skunk 2 valves, springs and retainers, weisco pistons and eagle rods, 11.5-1 compression, aem 3"cai, 70mm tb, fully ported intake manifold,390 injectors...

Remember Im wanting to turbo this so that's why I want to know some bore and stroke setups and things

Now I'm know I'm going to have to sleeve the block but I'm asking if anyone knows so setups for a good street and track car, like how much I should bore it and what I should stroke it to.
Please I need help soon

you need a goal dude, hard to help you without knowing exactly what you want to do

and the whole bore and stroke thing bit just throw that out the window and keep it simple

your compression is a tad high as well for any decent amount of boost on pump gas

Well I figured well i had it apart and getting it sleeved i would bore it over since I had it already all apart, and I wanna make around 350hp or so to the wheels, and yea when I got it sleeved I was going to go with 10.5-1 or 9.5-1 compression but I wanted to get some ideas

dantamparacer

personally i would leave the stock bore and stroke. You might be better off selling your bottom end and starting over so you can get some of your money back out of it. Because 11.5:1 is kinda high for a turbo street car

Yea true, but to change the compression all you have to do it get different pistons correct? I'm not sure just asking

yea to change the compression all you have to do is get new pistons

boostedteg69

you could get longer rods theoretically or high top pistons and milling the head would raise the comp also

if you only looking for 350 get a ls block with some pistons in rods a good turbo and fuel set up and you will make 350 easy

Your setup is fine, just get bigger insectos and a nice turbo and you'll have no problem making 350. I have a stock b20 with a b16 head with head studs making 446hp on 12psi with a 60-1 and e85. Stock sleeves will hold power as long as you have a good tune. With your compression it'll easily make 400 on very little boost.
