So Im currently building an 82 z28 into a turbo tpi car. I have a l98 tpi long lock in the car with carbed intake. I also have a 89 I believe tpi without cold start etc. I'll be using megasquirt to run it. I'm going remote mount because I already have the parts. I'm removing all the oil system. Pump turbo. Etc from my 01 Silverado 5.3 that I had rear mount turboed. It's a fun truck but the weight makes it a little slow. I've seen pictures before of this done to a third gen. Just looking for more. Or advice if you've done it. I have everything basically planned out aside from the charge pipe routing and the actual turbo mounting. Considering the major opening under the passenger rear muffler spot. I may turn it sideways and run open downpipe straight out. Just gathering ideas.
The fourth gen has slightly more room under it and also due to the body. It doesn't sit as low back there. My car already is lowered and need to keep my chances low of something hitting it. I wanna see actual third gen pics because I KNOW people have done it. Lol
I am putting a 4th gen gas tank and rear in car currently. Mine is a 305 tpi car all stock. Running new replacement 2.25" exhaust to rear and putting an On3 T70 there. Looking for 330-350 whp if i can.
Eventually want to rebuild motor, mild cam, refresh heads maybe vortecs, and some kind of intake either hsr or single plane efi like i have in my other car. Or ported tpi with slp runner if i canfind some under 300$. We'll see
Something like this
I was planning on coming out of compressor into an intercooler mounted under trunk next to turbo and then running down driver side. But now i may look at a cooler up in the nose of the car. We shall see. It will be hot air low boost setup initially
Mine is gonna run no more than 5psi on a good day till I finish the 383 bottom end. Then I'll be running 15 psi with watermeth injection and possibly e85. Until then I gotta get the turbo plumbed and what not

I was thinking the same thing with the A2A IC in the rear on a planned 4th gen car. Sort of going back and fourth with the A2A or just going A2W IC in the rear. You running the check valve in the inlet oil line or doing the outlet sump? I plan on doing a small sump with no check valves at all using 1/4" feed line and 3/8" return line from the oil pump.
I've got a couple of pics on my desktop of a guy in Edmonton that did a RMT on his Camaro.
He cut and raised his trunk well which gave him lots of room.
Ran 11's on a carbed setup if I remember correctly...
I'll post pics of it later
I'm not a fan of factory computers. I like standalone setups. Seeing as I feel it's a little easier. I've tuned my truck with hptuners. And really wish Ida went standalone. There's so much factory crap to do away with. I spent more time tweaking that then actual tables.

No sure what you mean. I wasnt doin anything special at all. Just -4 feed and -6 to -8 return depending. Ofcourse if i could do it with non braided line for cheaper i would but i have -4 feed already.
Without check valves, the oil feed will drain into the turbo when the engine is off. The drain may do the same depending on the location.
Check valves can stop this from occurring, or a small sump can be installed on the return side under the turbo to catch the fluid from the lines instead of overflowing the center section and leaking into the compressor and turbine.
Hmm. Havent heard of that before. Never had an issue on my twins and it doesnt have check valves or sump but they do drain vertically for a few inches. I'll have to look into that
Mine doesn't do that either and I have a 90 at the bottom of the turbo. So there's no where for the oil to drain without the pump. And I've yet to see it build up and leak. I've put 1000s of miles on it so far. I'm getting other things sorted before I get this turbo on. Gotta finish up a few other things first.
I guess you could add a timer function to keep pump running after shutoff. I like the ls1 pcm for this, it allows fans to run temporarily. Could tie into that circuit for scavenge pump but i wont be doing another 24x setup
Your front mounts have drain line under them before the pump. That is your reservoir. Short distances are fine.
amount of oil in a line = ((LINE_ID/2)^2)*3.14 * LINE_LENGTH * 16.38 mL.
Suppose rear mount with 4/16" line with 3/16" ID that is 15 feet to turbo. That is 6.7mL. Not much, but if the remote pump is higher than the turbo then that line is back draining toward the turbo too.

I don't like running fans, timers, etc after engine is off. I was going to do the turbo timer thing with the PCM I have until I did the calc to see how much oil I would have to move.
Sump doesn't have to hold much at all. Just a little piece of 1" pipe is plenty big enough.
I am running 1/4" feed and 3/8" return for low press and high press sides. Only about 10mL of oil to sump.
You would have to have it so high that it develops enough head to back feed the turbo drain port. There really isnt much oil in the drain lines when the turbowerx pump is going, atleast from what i've seen.
I may run a few inches of dead vertical off the drain but planned on a few runs of horizontal line depending where pump ends up being mounted
In my experience I feel no need to have any oil left in the turbo removed unless it was serious inlet feed. Me and a guy were talking that if all the oil drained or was pumped out after shutoff. During startup you would have a short time that the turbo would spin and have no oil to the bearings. This is minuscule amount of time but it's a thought to ponder on.

All parts within an engine and external to the engine (turbo) are coated with oil before they rotate. When the engine starte to rotate so does the oil pump and applies fresh oil.
Calc the time to fill a 15 foot 1/4" diameter line. The volume is 7mL. By comparison, that is about 1/4 of the size of a standard wiskey shot.
Not really for the third gen. I swapped over to some vortec heads and Intake for now so should be close to 400hp crank. As for the turbo well it managed to get put back on my Silverado build and then to top it. I bought an 03 wrx to play with
