I called today to ask about rebuilding my turbo and the costs of getting them beefed up. He said they can take our stock hot air turbos and go up as far as a ta52. Is that right? If so, im going that way. If not, what is the BIGGEST i can go with the stock turbo?
destroyed turbo, precisions stock hot air to a ta52????

Limit will ONLY rebuild your stock turbo to a TA33. a few people have asked them about going bigger, but thats all they will do with our hotair housings. if you want to go faster than mid 12s and retain the stock hotair turbo housing, you have to send it out to Precision
Yeah, i just got off the phone with john at limit. he said that the 33 is the biggest they will go. He said its the carbon seal that is the problem. He said if it wasnt there, they would go as big as they could. He said if it was setup like the 86 87 style, it wouldnt be a prob, because of where the throttle body is at.
Precision told me they can take it up to a ta52. Isnt that in the 600hp range? Are they good quality when they come back?

I think I will be following this thread :wink: We spoke about this in a thread awhile back after I had communicated with John about the carbon seal issue.
So come on people someone answer his questions, I want to know too Anything new ever transpire with this issue?

Anything new ever transpire with this issue?Well, i have more student aid than I need, so im pulling out the rest to help with bills, and gas and such, and putting a grand on the turbo and and new injectors. I think I might go to precision for it and have them do the ta52 upgrade. A 600hp capable turbo is more of what im looking for. JUST because I would rather have a little more, and not have to max out a 33 later on.

Not sure what or where the carbon seal goes
Only one I know off. At the down pipe (Doughnut type carbon seal)
Spoke to a vendor who does noting but seals and gaskets of all sorts.
Told him about my "project" and told him I may have a market for him with specialty seals. If anyone can make seals, these guys can! (Trust me on this one)
I am not looking to make any $, but if someone get me a drawing or sample for the carbon seal, I will work with the vendor to develop the seal and turn it over to the experts.
It's the way the turbo is made, Carbon seal vs. Dynamic seal or blow thru vs. draw thru. It's got to do with the throttle body placement. I know my PT-51 has this seal because my buddy bought it for his HotAir and couldn't use it so I swapped him my TA-60 which he did use. As far as the TA-33 goes, I know someone here locally that has had one in the high 11's. It's all in the tune. If you do go bigger think about using a reclocked TA-49 (86/87 style turbo) or prepare to get a bigger stall convertor and injectors.
Didn't we already answer this question for you in this thread?

Kind of. The guy at precision told me that instead of making it bigger, i need to focus on electrical stuff first. I just need the damn turbo rebuilt. it is show to hell. Why not just go big with the stock housing and be done with it, instead of getting it rebuilt, and then later on sending it back in to get redone to a bigger size. Seems stupid to me.
Now, im guessing a ta53 or ta54 is a little stronger than a ta60, but how bad is the lag on one of those? ALso, how big of fuel injectors would you guys use? obviously i would need a new fuel pump and hot wire kit. What else exactly? How much pressure could i run on the new turbo compared to the stock one until i could get a good tune?

I have a little experience in this area although it has been beat to death. I've run an 86-87 TA49, 84-85 TA62, and an 86-87 TA64/66.
The 49 in the 87 housing leaked a small amount of oil into the intake when it was a suck through. The 62 in the hotair housing also leaked oil when used as a suck through. I converted the car to blow through with the 49 still on and it no longer leaked oil that I could tell. The 64/66 that's on the car now is perfectly dry after 20,000 miles and has always been on the blow through setup. I have a friend with a hotair that also had oil control problems with his 62 in the hotair housings and the suck through setup. I don't know the reasoning, maybe the carbon seals can't be used with the bigger turbos. I'm not sure, because my 62 was still a small shaft turbo but I would like to find out why John won't go bigger than a 33. I'm sure he has a good reason.
I don't know how lag will be with those turbos you mentioned. I had a friend with a 52 that had horrible lag but most people say they spool great. My car couldn't spool the 62 until midway through second gear with the old motor yet the 64 literally spools almost like a stocker with the new motor. It matters on your combo and tune.

Dont forget - its not how big your turbo is...or its not how big your stick is - its how you swing it.
I have a 33 and it works great - got it from John at Limit.
You have to do a bunch of things to get results...not just one thing. Dont blow all your dough on a big turbo - 'cause you might be surprised later when you dont get the results you expect. I have no current plans on upgrading my 33 'cause its lots of turbo - just check out the grin it puts on my face.
The 33 is a great turbo and flows way more then the stocker. You cant go wrong with it. Its a great street turbo. Work at your car bit by bit and take advice from the guys on this board - thats what I did years ago and it paid off in tire rubber.

Hey buddy
Hey bro, Im switching over to a turbomotion intercooler with the throttle body on the intake instead of the turbo.
I have a brand new TA-33 turbo with a larger exhaust housing done by John at limit with about 50 miles on it (NEW).
Im going to talk to my buddy Lee, and if I need a different turbo for my setup, I will sell you this one. Ive got about 700.00 in it
Tell you right now though, on a mild hotair car, that turbo is amazing.
I could even sell you the throttle body on it since Im switching over to an 87 TB. I have a mease DP, but still have the elbow from Limit that is ported out.
