STS is Junk stay away

[cjt037]

The sts kit for our car is complete junk. bad cheap parts will not hold up under boost at all.

List of problems in order
kit installed march 2011

March 2011 have to weld inplace of most clamps.
March 2011 Several sleeves replaced
June 2011 First turbo replaced
August 2011 several issues with wastegate locking
Dec 2011 pcv fails causing engine failure
Sept 2012 pcv fails again caught in time
oct 2012 second turbo fails changed to non sts turbo
dec 2012 Oil pump fails


Changes made to kit are to much to list. Take this for what its worth. Trying to warn people off before purchase.

radiator style screw clamps....not good for boost. We replace with T-clamps and also all the charge piping has just 3 dimples stamped in to prevent it from separating under boost. We remove and bead roll all critical charge pipe ends.

June 2011 First turbo replaced
The system is designed with the wastegate so far from the turbo the lateral pressures on the shafts causes failures in no time. We change to Borg Warner EFR's w/internal bypass/wastegate or standard BW turbo with wastegate at the turbo. The way they sell the system the turbos are about guaranteed to fail in short order.
August 2011 several issues with wastegate locking
Dec 2011 pcv fails causing engine failure
I have seen some messed up crankcase evac systems on FI kits....but this is one of the worst. Have no idea what they are trying to accomplish, but it is a nightmare for somethin relatively simple.

We of course replace with complete RX dual valve FI system that not only traps all oil from ingestion, but is the only one that provides proper evacuation during both boost and non boost operation.
Sept 2012 pcv fails again caught in time
oct 2012 second turbo fails changed to non sts turbo
Unless the wastegate is located at the turbo to be able to release pressure immediately when needed the design will take out even a good quality turbo.
dec 2012 Oil pump fails
Very common. Always replace with an upgraded one....Turbo Werks being about as good as they get.

Your not alone......not alot makes sense in what we see in these, but any good turbo shop (like the one you had correct it all) can make the kits good & reliable.

NOW you can enjoy it w/out worry.

Not a big fan of the STS rear mount set up

Wow that's a lot of issues, glad to see you get them sorted out CJ! ak, Don't let STS discourage you about rear mount setups though, there are plenty of benefits of a proper rear-mount setup.

PT is correct. The theory is sound and proven.....we do them and have a steady stream of STS cars coming through that we redo to operate correctly with great results.

HONESTY THIS IS ALL CORRECT STS IS ABSOLUTELY TRASH!!!

1)I've had to retune the car 3 times before the meth kit because it was to rich and then to lean.
Then I retuned the car because I put a meth kit in and it took Vince another 3 different times to retune and then when he retuned he forgot to take out the code for my headers so I've been driving with an engine light for 3 months because I can not get a hold of him.

2) I had to replace my oil pump or there would be a haze of smoke from the excessive oil because the pump could not drain it fast enough.

They clame 400 to the wheels with a base tune and I struggled to get that with the methonal kit at 9 pounds of boost.

VINCE AND STS ARE BOTH PEOPLE AND COMPANYS I WOULD NEVER RECOMMEND.

Vince isn't even a real tuner IMO he's just a software guy and he should sell his company to a real tuner.

Sts can not make a good rear mounted turbo because the parts and the qualty of the kit is so poorly designed.

I haven't ran into an wastegate issue yet but when I do does anyone know what I should do about it?
