building my own sts kit?? just wondering if any one has built there own in here. what they have used to oil the turbo.
i dont have any problems building the kit, my only issue is oiling the turbo wich i dont and WILL NOT "just get by" i was thinking of buying the STS oiling kit and calling it a day
i have a cummins diesiel turbo that was jsut rebuilt. it was on a s10 with a tial waste gate and BOV pushed by a l98 350. it was nasty with 7 psi
so i was just wondering if anyone has done this any suggestions i should look out for or ideas on how to make it better espeically OILING THE THING
thanks

You can build a much better system than STS provides.....for a lot less coin. Use a Mocal pump fo the return. For the feed, tap into the plate above the oil filter housing. It comes out w/ 2 bolts and on the Corvette is actualy tapped for the oil pressure gauge. This is exactly what STS does.
To put the oil back in the engine.....a bung back into the oilpan is best. Into the valvecover 2nd, and STS into the cap last (tends to leak if it's not cinched down tight.)
You'll also want a 1-way check valve on the inlet side just before the turbo to prevent the oil feed line from driooing oil into the turbine while the car isnt driving. Failure to do so will cause the turbine to pool w oil....and blow past the turbine rings into the exhaust and intake pipes.
Total cost for all this (buying new) would run around $400 (counting AN line, fittings, etc.)
Check this post....lots of pics to help you out

yeah the day i got my used sts kit i got chopped up and the only thing left that looks like the sts setup is the turbo and turbo back exhaust everything got changed the inlet side, pump, line routing dont get me wrong the sts kit is a good design but i made it a little better ill try to post pics soon hopefully plus i added a FMIC so that changed alot of stuff

damn im beside myself. i think this is the most help i have ever gotten on this site lol
schantin: were can i purchase this mocal pump at?
and hey just a thought process for ya if u could do it cheaper to make some money u should put a new oiling kit together and sell it. because the chances of some one like me not gettin the right lil tiny fitting are very likly...... wink wink
and another? im only gonna run 5 psi considering the motor is stock but tch. 4 with an intercooler how much bigger injectors will i need with this
and i know iam gonna get it tuned by either Bret @ F-Body central or jeff at PSI but how important is a tune with that low of boost?

Your definetly going to need a tune .
I am doing my own custom kit still in the process though ,so no real llife experencecs yet. But form my reserch I am going to use the linginfelter oil tap -4 an to the evap hard line that runs to the back and then another -4 form the back of the evap hard line to the turbo with the check valve and restrictor . I feel this way will lesen the chance of the line rubbing something and dumping my oil . Then -10 to the pump (morcal)form the pump to a welded fitting in the valve cover .
Anyone have a picture of where they tap the pan in the rear mount I would do it like that but not sure where would be good . It would have to be above the oil level right

i had thought about build a res. close to the turbo also then i figured about room.... its plenty to hold the pump but what kind of oil cooler could i fit up there that was going to get nice cool air, so iam just goin to tap the oil pan and keep it simple and splend alot of money on steel braided lines DAMN

I used to suggest the TRT FMIC, but they're out of business now. You really do need a FMIC. Pre-intercooler m IAT's were 150+ in traffic w/ 80 degree outside air temp. Post FMIC the IATs dropped to 100-105 degrees. This is a massive difference, as the computer is pulling timing above this temp. I'd suggest contacting SpeedInc or similiar for an intercooler setup.
Tuning is mandatory. I only ran 5PSI of boost when I had the STS on the car. It would have blown the engine clear out the mounts if I had not tuned it. The Ve table increased in values as much as 35% in certain areas. Not to mention timing changes, new injector maps, reprogramming the burst-knock on the knock sensors, etc.
Good luck w/ the build. Feel free to PM me if you have any more Q's.

welll i may be a newb on some things. what do u mean by SAE conversion and how long to u think my stock motor with 133k will last on that boost...... i have already came to the conclusion that the A4 is gone as sooon as it hits boost but thats ok....
for that ten minutes shes gonna be running it will be great

you should last a while at 5 psi...it all depends on the history of your car and if its ever been re-built (engine and tranny wise) and also who did the job or how much the car was abused over its lifetime. Or it could just blow whenever it feels like it, its a coin flip. Either way i say go front mount turbo, i have one for sale that keep a/c if interested...made 520rwhp/550rwtq at the wheels at 8 psi. You could set it up for 5psi and you'll be good to go for a while, while still making enough power to shat urself lol

thanks for the offer fenix but i gotta decline. im a broke bastard , im gonna by everything peice buy piece, we own a small exhaust shop so im gonna make the pipin for it so that wont cost me anything except time..... my main issue was the oiling kit tuning nd injectors. i have the turbo waste gate and BOV . so one i get the oiling down ill go to injectors and so forth.
but trust me if i had some cash laying around i would def. be game for buying but thanks for the offer anyway
i would like to say thanks to everyone here that helped me out i have been stumped on this oiling issue for a long time and thanks everyone for your feedback

It would be cheaper and "easier" (per se) to do a front-mount. Lot less piping. Less couplers and clamps. No need for a return pump, as you can gravity drain a front mount turbo back to the pan. Use truck log manifolds (check out the sticky) and weld the rest of the piping for the front. More labor than the rear-mount, but again, you mentioned labor is free.The rear-mount will work well, but in your situation....the front mount is doable and in my opinion (being a former rear-mount owner) the better way to go. Better bang for the buck
BTW, more than happy to continue helping answer Q's w/ the rear-mount setup. I could build one of those in my sleep........ I had it apart that many times
