Okay, so I've been searching the forums for about an hour now and can't find the info I need. My question is what Exactly do I need to turbo my 420a. I did a dry compression test and its 120 across the board haven't done wet test but the numbers were 120 even. So I am under the assumption the motor is good doesn't leak or burn. It's a 5 spd and I run full synthetic aside from that ideally after its said and done I want to run about 20psi after I build the block and head up. For right now I would be content with 5-10 psi of boost my question is what fuel mods do I need. I have an idea of what I need A/f gauge, boost gauge, 210 plh fuelpump, 10 gauge rewire. Now do I NEED injectors fuel pump and all that stuff or would a turbo kit, new exhaust, FMIC, boost controller and boost gauge be enough?
