My head hurts from all the reading and searching and I still can't come to a decision. I plan to buy the CX Racing kit, minus the turbos since I want to get a little better quality compressors.

Specs & Goals
80 Malibu @ 2900#'s w/o driver
TH400
12 Bolt with 3.31 or 3.42's
SBE LQ9, using stock 317's and will upgrade the springs, studs
Truck intake
Custom cam - Tick? LJMS?

Goal is high 8's, low 9's
HP wise, I think 700RWHP should get me there

No meth or water inj, plan is running straight 112-116

I know a large single would do it too, but I want twins, have tons of room for them.

Will be a purpose-built drag car, no street.

Either one should get u there but if it were me I'd go Borg sxe.

We just did 780rwhp in 16lbs on a lq4 with 2 on3 70's with a 228/230 cam.

I am biased. Mine are sxe 66/73's and twin scroll .91's , but with that said the cast 366's are had bitches and they make crazy power.

This and the option to upgrade wheels, housing down the line if you want.

.68's on the 70's
I also have eBay 72/68's with .81's on my personal car with a l33 with no issues spooling

TurboD, I have a LY6 6.0 with twin On3 70's with .96ar housings in the works now. Mind if i ask when urs start spooling and when is it all in?

Thanks all. I Think I'm going with twin Airwerks S300SX3 Turbo-66mm-T4-Twin Scroll-0.91 A/R P/N 177275

Turbo Specifications:
Compressor Wheel Inducer Diameter (mm): 66mm
Compressor Wheel Inducer Diameter (in): 2.6
Compressor Wheel Outer Diameter (in): 3.6
Turbine Wheel Outer Diameter (mm): 80mm
Turbine Wheel Outer Diameter (in): 3.14
Turbine Wheel Exducer (mm): 73mm
Turbine Wheel Exducer (in): 2.89
Turbine A/R: 0.91
Turbine Inlet Style: T4
Scroll Type: Twin

I see them on ebay for around $580, but would much rather support a sponsor. Who has the best prices?

I figure these with a pair of JGS 40mm wastegates and single JGS 50mm bov should do the trick.

Very nice build. Your Bu looks very similar to mine, engine compartment wise. Do you have a build thread? What's your hp/et goals?

Rob07002

Any further thoughts on these turbos? Too big? Would like to see maybe 5-6#'s by 3000-3500 rpm

All in by 4500-5000 depending on the boost

You ever figure out your power issue with the 72/68's? Seems like great turbos but I know you had extremely low numbers on the dyno

Not really, switching a few things up this winter and adding an intercooler.

Just started my twin turbo build and will be using the same s366 turbos, did you decide on an intercooler I have heard this one "Treadstone Performance TRTT 1000HP Twin Turbo", is a great choice has anybody else used this intercooler ? I was going to use the truck manifold but have a TBSS intake coming tomorrow it looks to be 1/2 -1 in shorter and has better flow, will be running 3.42s as well.

Having a budget, I've decided to fab as much myself as possible and spend the money on the good parts and where it's needed. Likely going with that exact Treadstone IC, although many I've seen on here also run CXR with no issues. Can't afford a Bell or Garrett. I think I'm going with Flowtech/eBay up and fwd headers and some CXR T4 to V-band elbows. JGS 44mm wastegates and singe 50mm BOV.
