LB7: LB7 s369sxe

[bigmackmiller]

Hey guys, I am wanting some opinions on a turbo upgrade. I purchased a pieced together s300 kit on a Craigslist find. It came with a HSP pedestal, fleece install kit w downpipe, charge pipe couplers, S369sxe, and an ats intake. Will I need anything else to replace my factory IHI? Considering upgrading charge pipes, ybridge or both, truck is currently running 65% SAC inj. And have a 10mm ready to go on, tuned by Mark @ Danville

If your going to do a y bridge, best time is with the turbo out. Also if it has a lot of miles on it the up pipes can be a pain to get off. If you plan to do up pipes and manifolds it would be easiest to do it all at once.

Ok, considered doing the manifolds and up pipes as well, just wasn’t sure which would compliment the setup best

I've had the best luck with the profab manifolds and up pipes. They come with all new hardware so if you break off a bolt on the old stuff it's no worries. I can't remember for sure as I haven't had or worked on a lb7 lately but I'm pretty sure the factory intercooler pipes are 3". Someone will check me if I'm wrong

Yea believe you are correct except for small portion on driver side

Yes where the boot goes on from the turbo I think it is knocked down to 2 1/4.

You will also need coolant plugs and a plug for the valley oil return.
