Comes with all the bushings, seals, clips, bolts, etc. If this is even the right kit for this turbo. I’ve done tons of looking online and can’t find a definitive answer on what model turbo this even is.

Fun fact, they made like 112 FWD NA LeSabre Grand Nationals in 86. So weird.

Anywho, is there shaft play in that turbo? It sorta looks like the gap between the turbine wheel and the housing is pretty large. When the bearings go the turbine wheel gets whittled down by the housing=not good.

There’s about as much shaft play as in a gay porno! It’s bad. The wheel is a tiny bit peened over from making contact. I’ve been searching for a whole center cartridge, but every time I click on a link it turns out to not be for this turbo. Guess I’ll keep looking.

Looks like this gem has an internal waste gate. You will also need that. Did it come with it?
There is a vacuum operated diaphragm and a cover with a linkage to a valve the opens and closes over the smaller port.

Mo,
The Ebay turbos are cheap, but they don't last long unless you take really good care of them - as in running super quality oil and keeping it really clean.
Guys at the shop have run them, but they beat on them as daily drivers.

The amount of driving that Pants will do... an Ebay turbo will last forever...

A suggestion:
Buy an external waste gate turbo. They are much more flexible to work with and you also get the waste gate sound - for what that's worth...
More $$ since you also have to buy a waste gate, but much better over all.

I’m gonna run an external wastegate. I found an exhaust flange on eBay that deletes the internal one. Just covers the hole.

Starting to construct a plan for the turbo exhaust setup. I’ve got the stock EFI manifolds.



And I brought home the Aviator Y-pipe.



The flanges match right up.



It’s a ball and socket type joint, with no gasket. Only issue is the ‘ball’ on the manifold is about 1/2” smaller in diameter than the ‘socket’ on the pipe. So I need to find, or make a thin donut type gasket to fill the gap. But that shouldn’t be hard.

I’ll be using the flanges, the Y section, and probably a bit of the pipe after the Y. It’s 2.5” into a 3” Y, just like my current exhaust, so I should be able to reuse my current muffler and tailpipe.



As far as turbo location, I’m gonna ditch the heater box, and maybe trim some of the inner fender.



This should give me enough room, depending how the inlets and outlets of the turbo point. I’d like to run the air intake up into the blower motor hole, and be able to draw in cold fresh air from the cowl. That’s the plan, anyway.

I also got a little boring maintenance done. My E-brake cables have been seized since I bought the truck. Now that it’s a stick, I’d like a little more insurance from rolling out into the street than just leaving it in gear. So I replaced the cables. But, taking a closer look at the brakes, they weren’t in the best of shape. Shoes, hardware, adjusters, and new wheel cylinders are under $50, so I would be an idiot not to freshen everything up while it’s apart.



I’ll be picking everything up tomorrow, and getting it done this weekend.

You should keep your exhaust runs to the turbo as short as you can and either coat them (best) or wrap them to keep the heat energy in. Makes for less turbo lag.
:cool:

That’s the plan, man. Original thought was to keep the header and run a remote mount turbo in the bed. But even with a small, quick spooling turbo, you’d be able to time the turbo lag with a calendar!
With this setup, I shouldn’t have more than 18-24” of exhaust before the turbo. Maybe even less. And I’ll figure out the best place for the intercooler to keep the intake as short as possible, too.

Weird as it may seem... I saw several newer Corvettes at the track that were running rear mount turbos (twins) and they were in the 9s.
Didn't talk to any of the owners, but they were running super hard.

When drag racing with a RWD traction limited car turbo lag can be a good thing. Once the car is moving bring on the boost!

Believe me, Max, I’ve seen plenty of absolute monsters with rear mounted turbos. There were other factors than just lag, though. Price was a big one. Having to run a pump to pump oil from the turbo back to the oil pan, all the extra piping and wiring, etc. The cool-factor of a big ol’ turbo under (and possibly poking through) the hood. Although having one mounted in the bed would be pretty awesome.

EFI!!







My only complaint so far is how long the sensor pigtails are. The wires on the O2 sensor are almost 2 feet long, too. I’m gonna be tucking and hiding a lot of wiring to keep the engine bay as neat as I can.
