They will be. I have a set of RC 750CC injector for sale. They will be more than enough. I would recommend some type of FPR. B&M makes one for $30 or so that use a stock FPR modified. Also get a FP gauge that sits on top of fuel filter.

They come with a specially designed banjo fitting to replace the current one. They come with instructions. Very easy to do, less than 10 minutes.

you cannot pick injectors based on 8psi. you didnt give any details on the setup, most importantly whp goal and fuel type. help us help you.

in general i would say 360cc injectors are good for maybe 250whp on gasoline. you will need to mind your duty cycle closely

my bad, i plan on no more than 175-205whp... i was told my stock 240s could handle that w/ a fpr and fuel pump but i don't wanna take any chances..

i dont think the 240s would do 200wp especially on a boost engine with a higher bsfc. 360's might work on such low pwer. you could bump the pressure a bit to help out if needed
