Well just got a lq4 my original plan was a stock 4v and a 70mm so I bought all 3" coldside and a tial 38mm gate. Plans have changed and now have a stock lq4 6.0 with a stage 3 tick turbo cam ls6 intake head studs and gaskets.


I'm looking at 88-91mm turbos for room to grow when I build the motor


Can I just buy another 38mm gate and put one on each hot side pipe? Figure it would be cheaper then selling and buying a 60mm one


Now for the coldside how much will 3" pipe support? I don't ever plan on going higher the. 1400 or 1500 flywheel hp. Will 3" be ok or should I sell all my stuff and buy 3.5"? Car will have a big air to water if it matters?


I'm assueming a 88 or 91 is as big as I want to go on a stock 6.0 for now? I plan on running 110 and would like 700-800rwhp for now. If all goes well I will rebuild next winter

Yes, 2 38mm gates would work perfect. 3" is all you need, you dont need to go any bigger. Which turbo are you looking at? T4 or t6? A pt88 would work or you could do a borg t6 as well

I would like a t6 8847 or 91mm from forced induction that's what I have my eyes on right now

Do you know how far some people have pushed 3" pipes?

3" is probably all you need. After the 1000whp mark it might be a restriction but idk. what are your future goals? Is it going to be a manual or auto? Street car a drag car? Allot of things that need to bee factored in when it comes to choosing a turbo.

Full out drag car with auto, air/water ic

Will never go more then 1500hp fylwheel

Then i think the gt47 is a good choice. You have a Trans brake too? The 3" pipe will do the job

Yup has brake
