Get bigger injectors. Not to be the ******* here but, what exactly do you need help with? What are your goals?

The motor has zero miles from the machine shop. new eagle h beam rod and mahle pistons parts number LS1314905i16 Going to get an exhaust system, but I have a P1SC procharger and want to know whats needed to max it out or do i need to upgrade my head unit.

Well if your going to "max it out" u"ll def. want bigger injectors, at least 60lbs and maybe the twin it tank pumps. You can never have to much to be safe that could be a 800-900hp set up if done right maybe more, good luck.

What exactly are you trying to max out? The forged 347? The intake? The blower? The heads? No matter what, you will need more injector. I got a set of 60#ers with less than 300 miles on them for $300.

do not raise the compression unless you are planning on using meth. you should be able to get it to 18-20psi of boost without any meth.

i have a 8.6:1 motor

i do not really know at this point. all i can say is that on 10 psi my car does 12.1 1/4 mile on factory 245 tires and factory 4l60e, with a leaking turbo header.

the low compression does make it feel a little less responsive when it is off boost. but i like to have some room for error in case something goes wrong
