Boosted MightyMax
I have some experience building ls engines and did a lot of research and sorta kinda have an idea of what I want
600 rwhp
-2002 4.8 Stock just below 175k miles (laying around our shop)
-lq4 cam
-ls2 intake possibly keep truck intake
-80lb dieka injectors
-044 Bosch fuel pump intank
-front sump GTO pan
-GT45 turbo kit 69mm kit or some "Cheaper" Borg Warner i was thinking about the s480
-pumpgas
-looking to run 10's
My questions are...
-if the gt45 can't get me there maxed out is there a cheap Borg Warner that could work I was thinking s480?
-I want to run e85 but it isn't really available here so should I run a meth kit?
-I wanna send the pcm out to be tuned what company should I send it to?
Im doing a similar build it’s a 5.3 with a LQ9 cam (good for 40hp over the stock 4.8/5.3 cam). I have been to 15psi on 93 pump with wiper fluid as meth on the street.
I like using actual BorgWarner's, but people are having good results with the Chinese clones.
I would run a meth kit with pump gas. You could probably get away without it, but it's nice peace of mind.
Hopefully you're just sending out the ecu for a base tune only. It'll be hard for them to dial in the tune without being there with the car. If you're able to datalog with a wideband and send those back and forth, you can have pretty good results remotely though.
Getting the car on the dyno with a good tuner would be better.
