FS: Rear mount turbo exhaust and intercooler piping w/ scavenge pump setup
sold sold sold
Around 1500 miles on this stuff. Selling because I decided to go YSI to make the car simpler and not have to worry about anymore converter adjustments. Also this thing is loud at cruise and as I get older that annoys me.
Some details. The piping is 2.5" off the manifolds to a single 3" merge to the T6 turbo flange. It's setup for a Turbosmart or Tial 60mm or Precision 66mm wastegate. Absolutely no boost creep. With referencing the intake manifold for your boost reference it make 10psi around 4600 on a Forced Inductions Billet 76mm with 96mm turbine wheel. There is a bung in each side off the manifold for the OEM o2's and another bung for a wideband after the merge. The intercooler piping is 3". The intercooler inlet pipe was "massaged" to clear the Dewitts radiator I installed later on. The coldside pipe is still flanged for the MAF but I only used it for air temp readings. With BOV placement I recommend running in speed density. The cold side pipe as 1/8" NPT bungs for meth as well. It's flanged for a Tial 50mm BOV.

This scavenge pump setup works perfect. Absolutely no smoke ever. It drains to a reservoir via a -12 bung placed midways in the canister and then a -8 pulls and feeds the pump and a -8 returns back to a bung you need to weld to the valve cover. I had it wired so it only ran when the fuel pump was on. It feeds off the plate right above the OEM oil filter. It's a -4 feed.
On a stock LS3 with Valve springs only it made 670@10-11psi on straight pump 93. Leaving with no boost and only make 2psi in first gear it ran 10.63@137mph on that setup and a 17" radial. That was a 6.9@105 1/8th.
We made over 820whp on pump/meth with a cam on the same stock LS3 and 13-14psi. Ran 6.6@111 in the 1/8 making 760 and once again no boost and only 2psi in first. Easily a 9 second capable setup even leaving soft. I would keep it but not dealing with pulling my converter again and would rather spend that energy on the LS Fox car I'm doing.

All of the stainless on the hotside is tig welded and back purged. The oval IC tube is stainless as well with some scrapes since it ran under the k-frame. The rest is aluminum. Both the exhaust and IC used the OEM exhaust supports. The muffler will fit any Borg Warner turbine housing with 5" outlet. I can include the straight pipe too. The muffler did help but it's still droney. Only couplers it won't include is the 3" 90 off the FMIC and the 4" on the TB.
Asking $1800 shipped within the contiguous 48 states. Over $600 in the scavenge setup not including custom reservoir, probably another $1000 in material once you factor in 3" vbands, and 12-14 hours of welding. The only thing you will need is to weld a support bar for the turbo to hang. Thankfully the flange was designed with extra bolts so you could mount to something.
Any questions please ask. I recommend checking out the build thread as you can see a lot in the pics.
Thanks

Awesome.
I just picked up a 2009 Corvette 6 speed. I've been planning for a rear mount, and currently only have the Turbo. ( Comp CT5X 7285 Oil with T4 Divided & a T6 Divided housings ). I've got other Fuel system upgrades & HPTuners to get started.
Did you notice any Improvement when wrapping the exhaust?
If I wasn't so broke atm I'd be all over it.

Intercooler, BOV, turbo, and wastegate and 3 couplers (coupler to IC, ic to cold pipe and cold pipe to TB). Obviously the intercooler would require brackets as well.
I still have the turbo and wastegate sitting here though not being used so they could be purchased as well.
