Another Turbo ID Please

[Flyin Brian]

Please help ID this turbo. I have had it since I bought the car. I think it is a TE62E but want to know for sure.
I know this turbo is at least 10+ years old or older. Journal bearing. Here are some pictures. Thanks.

I measured the compressor wheel inducer and it is 58 mm. With a 75 mm exducer that would make the trim like 59.8. It is a 6 blade and I think the t60-1 compressor wheel has 7 blades. Turbine is 11 blade with an approximate exducer diameter of 64.8 mm. Looks like a P-trim maybe? So, I do not think it is a TE62 or a TE60 due to the 6 blade compressor wheel. But what is it then? What HP would it support? My best time was 11.6 at 112 but that was a bad tune up and it was driving through the converter bigtime. My goal this time around is high tens without pushing it too hard so I will be changing the converter of course and possibly the turbo as well if needed.

P trim turbine with a 58mm TE44 compressor. I didn't know these wheels were used together. Don't know what it is referred to as. This is the 2nd one of these I have seen.

Its hard to tell if thats a 69 ex wheel or a P trim. But looks like a clipped P. The exducer on the P is 2.542" and the 69 is 2.420". Its a huge mismatch of wheels since the turbine appears to have clipped blades also. Just a switch to a 60-1 compressor would give a huge increase in mass flow potential. With a similar turbo a friend went 11.60@117mph with a lot of converter slip about 12 years ago. Then we switched compressors and picked up about 10mph with no other change but the chip and re-tune. He had cam and heads that could take advantage of the increased mass flow potential. That turbo is a great place to start if you want to get a turbo that can support a lot of power a lot cheaper than new. 3000 stall@ zero required.

Thanks Forcefed and Bison! It figures that my turbo is a mismatched strange one, everything else on the car was wrong when I bought it. That small compressor explains a few things. I was getting really high intake air temperatures after the stock IC (235F at only 16 psi boost) before I switched to the FMIC. My heads have a TON of work done to them so I think they should flow good with my cam and a better compressor. My worst problem is still my converter. It is a 3500 stall 5-disk vigilante. I picked that out a long time ago when I thought I had a TE-61 turbo and the motor was mostly stock. Now with the stroker motor I am driving through the converter bad. I found my last timeslip of 12.0 at 112 mph (tire slip off line). Powerlogger shows me in 4th gear at around 5400 rpm at the end of the track at 25 psi boost. I do not lock the converter as I am really afraid I will break something even though my transmission is well built. I had to put the biggest springs in my wastegate to get 25 psi by the way. I plan on getting the right converter later this year (probably a PTC N/L with 3000 stall?) and maybe a new turbo in January. Thinking one of Bison's 6262 units would work good with my motor. I could just go to the 60-1 compressor but I checked the endplay and it is .006" and there is a little bit of oil making it to the IC. Probably would need a total rebuild. I think I am on the right track now to finally getting my combination right??

Converter and compressor swap would be a huge gain here. Whatever way you go .006" is too much end play and will get worse. I could recontour and re-balance with a 62 billet if interested.

Thanks Bison. That sounds like a good alternative to buying a whole new turbo. I will PM you about specifics on the 62 billet swap/rebuild.
