Guys with the APS single turbo kit could you take a look at the pics to see if I connected the oil supply for the turbo correctly.

Should there be an oil restrictor?





The cross over pipe is worrying me, it is cooking the paint. What do your installs look like?



Here is my oil temp gauge hookup.



Random Pics





Exhaust adaptor that I had welded up. 3.5" to 3"(was 2.5")

 

Can you do bigger pics? Like 800x600 or 1024x768?

 

I fixed them up.

 

Much better.

 

Looks good, but I don't understand why one would put the selonoid right at oil pressure sensor. Isn't it suposed to be right at the turbo inlet? That way the line does not drain/oil sit in the turbo?

Just my experience with the remot systems.

 

I uderstand your point that the oil after the selonoid could drain into the turbo, but that is the way APS has the system setup.

How do you know when to use an oil restrictor? With the oil pressure sending unit right there I know that I am seeing 60psi under full exceleration.

 

That looks right, just be careful of the "hard pipe" or the brass fitting that comes right off the motor and connects to the solenoid. I ended up getting a nasty oil leak, and finally figured out that the brass fitting sheared in half...and was basically hemorraging oil. I'm getting a built motor installed right now, and my friend is going to rig something up that comes off the block that shouldn't break from engine movement.

 

Let's get some more pictures now that you told me it's all done. Also some youtube videos if you can.

 

How is your car so clean on the bottom?

 

Despite suggestions that you do not need to add a restrictor, given the pressures the engine generated I ended up installing a 0.035" restrictor at the turbo oil inlet; resolved smoking and oil in intercooler issues.

 

i never had any smoking issues with my stuff...but i do get oil in the ic. though from what i hear...any turbo car has that problem.

wtf where you been joe??? how's your ride doing?

 

I was thinking of using a restrictor on the supply line, by the solenoid. Something like this, it is a .075" restrictor. Will that restrict enough pressure?

 

don't do it. if it needed one, it would have been included.

other thoughts. I don't remember exactly on the ST, but I know on the twins, there is a heat shield over the fuel lines you show in your third pic.

I would also do everything I could to find an APS ST exhaust. running the stock exhaust will not get you the best results. If you can't find the ST exhaust, you need to find something comparable in terms of functionality

 

Couldn't tell you; my information and education on the matter came from the owner of the local Garrett turbo shop (TurbosDirect) here in AZ - at the same time I upgraded to from a GT3542 to a GT3567 turbo... their recommendation with the GT series was to use a 0.035" restrictor.

Ugh... like the check valve, upgraded solenoid, scavenge pump, exhaust adapters, etc that were all released in a timely fashion by APS? LOL To each their own, but adding an additional restrictor when the VQ produces 60+ psi pressure is a nice $6 convenience while you're under there...

LOL - just got my ride back... long story, but GTM fixed me up, so now I can finally enjoy it after a longggggggggggg time of not driving it.

 

I agree the turbo should have a restrictor. As a matter of fact, 90% of turbo setups do and only 30% use them which is why there is such a large volume of turbo failures.

 

I installed the .075" oil restrictor and I don't have smoke everytime I let off the throttle. It runs really good like this!

 

all the best i had lots of fun with my kit
