I was thinking about maybe a 72mm, the spooling is the concern but I've seen similar setups make good power on sts kits with longtubes.

 

I went 11.35 at 118 with Lts and a sts kit. Decided to try them since they were already on the truck. It ran far better than I expected and I never tried stock manifolds.

 

Can you give some insight on your kit? Such as turbo location, size, scavenger pump (did you use a resevoir on return side of turbo) I am thinking this is the route i want to go and i am not looking for my 4x4 crew cab nnbs to be low 11s (would need some nasty power to get there) I am thinking more in the 12s range, i want reliability but some usable power that i can roll around with in a street tune but get a bit more serious with on track days. One question is on the VVT, would i be forced to go VVT delete or could i get a VVT comp cam from EPS? My plan is to piece a kit together myself based on other kits built by members and gearheads as well as by looking at packaged kits like STS. Anyone live in MN that has experience with mid/rear mount builds?

 

It was a sts kit. t67 turbo in place of the stock muffler. I would do the vvt delete. It had no return resevoir, but that would be a good addition.

 

Were you running a stall with this setup and was your 80e swap done already too? That is a sweet time for that setup and a great MPH too, whats the corrected DA sit at in the summer where you race? I'm sure that the altitude here affects my spool time quite a bit! Its usually in the 8000-10000 ft corrected DA range at our track in the summer

12's should be easy, i'd ditch the DOD also, one less part failure to worry about... with you having a 6.2l i'd at least go with a T4 S475 or a garrett/precision 76mm.

 

I gotta start doing my homework on turbo size, AR ratio, intercooler size, oil pumps, routing etc etc. Also considered a comp turbo Plan to build the kit slowly myself as my research pays off and I learn more about picking the turbo size. Already considering pulling off the ARH LTs and coating them to keep in some of the heat. Any good turbo literature i should check out for building my first turbo setup? Any good links to rear mount stuff?

 

I'd go with the Exa pump or a Weldon (too expensive and hard to find though)..... try tread stone performance for an intercooler, killer quality for the money just bought a TR12 4.5" cooler for my new setup.

Intercoolers: Intercoolers

 

I had a 2800 9 1/2 inch tq converter. DA was probably 1000-1200 best as I can remember. Temp was around 80 degrees.

 

Nice! I would love to have some race conditions like that one day lol!

 

Anyone have any experience with the comp oil-less turbos? I need to do some research into them, but the idea sounds sweet and expensive. I feel like a coolant line is more reliable than a oil line. My biggest concern is the oil return pump failure which i guess if it had a guage in line to monitor return pressure it wouldnt be too bad.
