Hey everyone I'm a bit new to the scene and have been trying to research my build. Just need some input on if I'm going in the right direction. I picked up a b18a1 block bored 0.25 over with matching p30 pistons, stock rods. I have a stock p72 gsr head with ARP head studs. Is this going to be too much cr for me? I have a walbro 255 and 440cc injectors. My goal for the car is 250whp around 5-7 psi on a gm4 borgwarner turbo. Tried searching but didn't see anything quite like what I have.

Your compression will be similar to B18CR and people boost those all the time. 11.5:1 and 250whp is cake dont sweat it. Just run 93 or E85 and get a good tune and it will last forever.

Great thanks for the reply. If I do go e85 do I need bigger injectors? I also have Hondata s300

Yes, figure at least 30% more fuel flow for the same power

For your setup it's all going to be in the tune. Get a competent tuner and you should be fine
