The built motor in my truck makes around 80 psi oil pressure at full tilt and I have no oiling issues at all.

 

Looks good only I don't see how it is any better than the new STS kit.

 

Did you tune this car or ever have it on a dyno? Just curious. I heard its a turd from some of his acquaintances.

 

Turbochargers do not have oil SEALS. There is more to just mounting any old turbo in the rear of the car. You have to size the turbo, A/R, and make sure you have the correct trims. The oil system is the easiest thing to do. If you decide to make this your self, make sure you do your home work on turbo sizing, Its hard since there are no curent charts or docs out there that tell you what correct size turbo, A/R, and trims you need to use for your build.

I work for STS, and I have seen time and time again 75 % of everyone who has tried to make there own rear mount turbo system, has spent 1000.00 more then our base system will cost. Now I am not telling you to purchase our system, just make sure you do your home work. I can give you some tips that will help.

Use stock manifolds
Wrap your Y pipe all the way to the turbine housing
Run a turbine jacket
Stay with 2-1/2 exhaust pipe
Use at least T4 frame turbocharger
Stay small on the turbine housing
Return oil in valve cover or oil fill cap

As far as the oil pump, I can tell you that there are alot of after market oil pumps out there that claim they can stand up to the punishment of the remote turbo system, I have yet to find any of these pumps and there claims to work as good as our pump. It took us years to find a pump that would hold up against the high demands and stresses remote turbo dishes out. The oil pump is the key to making this system a fun and enjoyable, for the daily driver. Now alot of people do not know this but here at STS I have a system that will sell you the propper turbo, our oil pump, and waste gate. This is out stage 1 universal system, it takes all the guess work out of finding the correct size turbocharger for you car, and gives you he same oil pump ran in all of our systems, and still allows you to build your own kit. I am not on here to sell our systems I am telling you all of this, so remote turbocharging wont be blamed incase the system you make does not work.

Good luck, and if you have any questions let me know, there is alot that I cant tell you but what I can tell you is remote turbocharging is a great way to make alot of safe power, if done correctly.

 

Exploded view of a turbo

Explain to me what you call the damn things, oil retainers, or what the keep the oil from coming out of the cartridge and either leaking into the turbine or compressor sides of the housing.

 

Are you running a -3an or -4an and what type of restrictor?

 

I see them as a way to make sure that the oil outlet is the path of least resistance.

 

I am running -4 line and since it is a remote mount I have a 2lb checkvalve at the turbo inlet. The turbo sees within 5psi of the oil pressure that the rest of the engine sees.

 

Yea the problem isnt the car its the driver. the car dyno'd 391rwhp, 480rwtq at 4.5psi. 105whp over what it made before. the car really didnt make a lot of power before for whatever reason. To date I have only seen him really lean on the car once and he suprised the guy he was running. We all thought the bolt SS was goign to walk him, but it was the other way around. The owner just doesnt have the experience and he's worried too much about it breaking.

I basically built it with a lot of the new STS ideas but that kit wasn't yet avaible it was several months out. As for better, there are a few minor problems with the STS kit IMHO. The charge pipe from the turbo and the oil drain to the pump are both routed over the axle. Like I said before I ran everything under the axle. Since the pipe doesnt turn left and go under the LCA it actually has better groudn clearence there and is less likely to scrape since it is directly in line with the rear wheels and not immediately in front of them. So going under the axle removes a couple 90 degree bends and about 2 1/2 feet of piping. Also with the Oil Drain running over the axle any oil left on the turbo side of the lube naturally puddles back in the turbo and leaks oil out the seals, under the axle the line is the low spot and the oil pump has an easier time getting the oil away. Also with an Intercooler the have the Wastegate boost reference straight off the turbo housing it tends to make for unstable mainfold pressures. What I mean by that is the Turbo will spool, create boost enough to openthe wastegate, but then it has a hard time filling the intercooler and all the piping so it drops about 2 psi or so between 4000 and 5200 rpm. I ran a hardline form the intake back to the wastegate and adjusted the spring to provide the correct manifold boost pressure throughout the entire rpm range, it seems to work much better. I'm not saying the kit I built is superior I just think it makes a little more sense.

 

If you have a restriction in your setup you will have oil coming out of either size of the turbo. The piston rings are design to keep exhaust from entering the bearing housing and vise versa on the compressor side. If your oil feed is too big and your oil drain is too small the oil will pass threw either side of the turbo, since it would be the path of least resistance.

I think people have had good luck with the Mocal pump.

 

What kind on check valve will work on the oil line

 

Here's My Custom Rear Mount S10 Set up, its twin TO4b's with .61 cold side and .84 hot sides, my own custom stand alone oil system, and rear mount intercooler!

 

 

Have you watched mythbusters? there is no air flow in the bed of your truck. that intercooler is not going to be good for much, it sure looks good though i like it.

 

Yes i have watched mythbusters and i have also watched leaves in my other trucks that always get blown under the toolbox, there is some airflow in the bed, we made several 0-100 runs and the inlet and outlet pipe temps where 20 degrees different everytime! It was mostly for looks anyways, but the IAT stays low and thats the goal!!
