Thinking about doing this. What do you guys think? I want to pick up a jdm b20b with low miles and maybe boost like around 10 pounds for daily driving. Will this motor hold up?? Let me know!

i wouldnt run more than 7 psi tuned. those walls are thin.

i'm running a b20z wich has a little more compression on a stock ecu and fmu setup and i'm running 8lbs no prob.......it's only been running a week so far but i've been pretty hard on it......

I am running a stock B202B with 8psi. It isn't tuned, but does run pretty rich up top. I have an FMU set up with 310's. Don't expect much power up top.

Thanks... anyone else?? Also any suggestions on what to do to build up the head?

my friend has a b20b stock bottom end with a built(ported, polished, cams, spring, retainers) ls head and is running about 8+ psi on it and he's having no problems and all of this is after about 10 bottles of nitrous on a 100 shot.

if you have injectors and good stand alone managment you should be able to hold 12-14 easy tuned properly on a decent condition motor...

the walls are thin yes but if spark is tuned and fuel is there then the walls shouldnt be an issue unless its ghetto tuned or your motor is beat
