Engine and Turbo Trims questions

[671]

Ok Which turbo trim would suite my needs a T3/T04e 57 trim .63a/r or 60 trim .63a/r. Goals are to hit 12's and want to see FULL boost around 3800-4500 rpm. minimum 8psi max 15+psi

B18b bored over to 84mm forged / balanced & blue printed bottm end. Also with the forged bottom end which would be a safer/better redline 7500 or 8200 rpm.

57 trim will meet your needs well
8lbs is low, stick with 15-16lbs to reach your goals
what comp ratio?

is the head going to be stock, dont push the head to much with stock parts plus we do not know what cams you will be using ls cams arent going to make power up that high you need to know where your cams make power and go after that

In all seriousness, the 57 trim should suffice.

I think most people will agree that you'll need to seriously build your block. The LS motor is a good platform for boost as stock internals can handle a decent amount of additional stress, but to hit 12s, you'll be looking into replacing key parts like your pistons, your rods, cams, etc.

Well 8 psi is for the daily drive but will be boostin 15+ at the track as for the head I'm not too sure If I'm gonna go with a b16 or the ls head either one is gonna be PnP'd complete vavle train swap of course and may be GSR/Skunk2 Turbo/Corwer Turbo cams still researching this topic. What do you think go LS/Vtec or just stick with the LS head

I will be using a forged botoom end

i have the 57 trim...i would have gone bigger but i wasnt planning on having a GSR when i bought it, still a very nice turbo and it will be going on my fully built 2 liter GSR

ls vtec is a can of worms, if its not built right then forget about it
