sent my wheels to get balanced and was told my turbo is a te50. Can't find much info on them except they have a slightly bigger exhaust wheel and were built by john myers.
 
Posting the wheel ind/exd dimension would get you accurate answers. Pics help too
 
I had one years ago and experienced boost control issues with it. Had to run 2 wastegates but it did work well once boost was under control. That was the beginning of the hybrid turbos for TR's. It might also be called a PTE-53 as well. Patrick would have to confirm though.
 
reed patridge is the one that told me this. He said they made them back in the mid 90s for full throttle. All he said was I was going to have to have a thdp and maybe a stall and it should work well with my current mods. I will call him tomorrow and get the wheel diameters. He said the compressor wheel is the same as the te44. I have no idea what the turbine wheel is though
 
The TA-50 was developed for the 1986/87 Buick Grand National/T-Type customer who is looking for a very responsive, yet powerful turbo for their modified V-6 Buick.
Perfect for the car with a small camshaft and cylinder head upgrade, 2800 stall convertor and other basic modifications.
The TA-50 is factory appearing and a 100% bolt on upgrade that will support 475 HP.
Utilizing the same 60 trim TO4-E compressor wheel as the TA-49, but a larger, more efficient T-350 Stage 5 turbine wheel for increased exhaust capacity.

The mystery is solved...

BTW I think that should say 575 FWHP unless the are talking about RWHP.
Precision rates the 4431 @ 565HP, this sounds like the 5152 basically.
 
the compressor housing not a stock appearing one. Reed told me 585 flywheel and he said he got one in the 10s if I remember right

That sounds about right, at those HP levels the compressor housing
don't make much to any difference.
 
Just thought I'd update this since I finally got to get some drive time with the car. Only running 21 psi, I haven't had any boost control problems with it. Not gonna run much more since I only have regular street tires. It's a dog down low with the stock d5 but once it gets going it spools fairly quickly. Breaks the rear loose at 60mph :) Probably wait and do a non l/u 9.5 stall after I have a trans built unless I get a really good deal on one.

Lmk how you make out with this. I remember a customers car about 3 years ago that had one of these and a d5. It was a complete turd. I think it ran mid 13's. I switched it to a te44 and chipped it and it went 12.20 with no other changes. Spool time was 1/4 of what it was with the T350 turbine. I also tried one of these on my blue car a while back with the wastegate wired shut and couldnt get past 450whp. The compressor was simply done. The engine was a low compression slightly over cammed turd but it later went 10.61 with a 60-1. TE50 is T04E 60 trim comp wheel and the expensive T350 10 blade turbine. Aka PT51 if it has the E cover. It needs a small stockish cam with a good converter to work properly. Kind of a mismatch of wheels imo. The 60-1 comp wheel would be an easy switch out and would work better on an engine with heads and cam.The 6152 uses the same turbine with the 61m GT35r comp wheel and doesnt run out of steam. The 61 comp wheel uses a bastard backing plate to be used on a t04E that makes it too expensive to switch out. The 61 comp wheel isnt cheap either. The switch out would cost close to $400 after machining the comp housing and paying the piper for the back plate and comp wheel.
 
Yeah it is a turd down low, in 1st it seems like it anyway. I do a 3-2 shift with it and it isn't bad on spool though, weird huh? Once it starts to spool though it jumps pretty quick, a lot more power than the stock turbo thats for sure. Unfortunately the nearest track is an hour and a half away so I doubt I'll be getting track times anytime soon. Yeah that turbine wheel was expensive. Around 125 bucks. I was gonna ask reed about upgrades but I didn't have any extra cash at the time. From what I've gathered the turbo is close to a pte53.

450whp, that's exactly what reed said. So as far as the roadblock you hit, was it just not making anymore power or was it that you just hit a certain boost number and that was it?

I'm not trying to beat a dead horse Bison, just not a lot on these oddball 50 series turbos and some info would be good on them. I can't be the only one running a 52-53 turbo.
 
I should rephrase my comment on the spool. Yeah it is a little slow first off. Kind of reminds me of when I had the car completely stock and no mbc on it. I'd say it takes about 1-1.5 seconds to start making boost and after a few lbs it skyrockets. It's kinda like having fuel mileage protection for when I'm driving around town lol

Also another thing that could be a factor in the spool is that I am running a standard pump gas chip with progressive devils own system. I'm just running -20 windshield washer fluid in it which could be evening out things since it's 50% water and I'm running a stock duttneck ic. Idk, just a thought. I haven't had to touch the controller or pump output even at stock boost setting. I've had to add quite a bit of fuel though on wot. Half throttle seems fine with no troubles, surging, etc. Idk what you guys look for with 02s and alky but I'm running .775 with no knock even on shifts.
 
It only made 24psi on that combo with the gate 100% closed. I probably could have squeeked another 15-20whp out of it with some timIng but knew I was going nowhere fast. Going back to the 60-1 on that engine put it back around 500whp. At the same 24psi the 60-1 was only around 460whp though. Shows even more that if you don't need it's not doing anything. The pt51 spooled extremely fast with the 9.5" ptc converter. Reed gave you a great deal on that turbine if he charged you $125. Even a good used one is usually more than that
