Turbo Question

[TURBO1]

I took my turbo shield off to clean it & I was curious on the "stock" turbo make. On the my compressor side it says "Garrett" (upside down) It also has on there, A/R 60 M24 R. Then on the turbine/exhaust side it says "Precision" A/R 63 M3 A G2, then engraved N168-87. Is this stock for a TTA? I'm just curious if there's away to decode it. Does anybody have pictures of their stock TTA turbo? (for comparison) :detective:

Does not look stock to me...has a bigger compressor housing.

Few more pictures & added some info on the first post. So, if this turbo is not stock, then what is it? TA49? Or something close to stock appearance. The previous owner told me it was stock, but I think he was clue less to a point & I'm finding stuff like the Pit Bull chip, explains why there's no cat on the exhaust. I would like to order the TT chip w/matching 42lbs injectors, but I'm glad I pulled the turbo shield off to clean it, otherwise I never would of known the turbo was different, if it is.

From what I was told recently if the lettering on it says garret and its raised its not a stock TTA turbo, if its engraved thats more original. I found out I actually have a stock GN turbo on mine.

The research I.D. on this turbo is kinda of a pain in the :censor: Theirs alot of reading info out there but very few pictures of stock turbos & the ones I do find, are for the GN & its to hard to tell buy the pics? Stock TTA close up turbo pictures are non existent, from what I can tell. I was told it was stock, by the previous owner, but I already heard on other forums also thats its not. I'm ok if its not, but I would like to know what turbo its is, so I can plan my work on the car accordingly.

Update: I'm thinking this might be a TA-49 with a Precision A/R 63 exhaust housing. Anybody else, have an idea?

It's not a stock turbo. Be glad that you have a TA-49. It's a tried and true upgrade from a stocker. It goes great with stock convertor, stock Throttle body. If I were in your position with your listed mods, I'd trash the Pit Bull chip and get a TT chip, scanmaster, replace your cat with a test pipe with a electric cut-out, install an alky injection system. An alky system is like insurance, you can safely run that TA-49 to 22 psi and alky on 93 pump gas. Match with 42.5 injectors. Your stock downpipe with an electric cutout will provide enough exhaust flow to get you in the low 12's if you tune it right. I've ran the same combo as I listed except I'm running a older NON-progressive alky system. I ran 12.20s back to back runs with no cool down time on fairly good NIttos hooking at about 1.8 60 ft times. I also had a TE-44, which is the same internal compressor wheels and turbine wheel size as the TA-49. The "TA" stands for stock appearing compressor housing. The "TE" stands for 3" smooth compressor housing. Basically the TE will give you a 15 hp advantage cause it's a smoother intake on the compressor side, but some people like the "stock appearing" look, kinda sleeper..."I'm just a stock V6 Mr. corvette". I prefer the TE, because it 15 proven hp for the exact same price, and right now I don't care about stock appearing. I got my stock stuff wrapped up in boxes if I want to do that in the future. Anyhoo, you got a better turbo than stock. Does the previous owner still have the stocker? You may want to track it down if you ever want to go back to stock for eventual future value.

If it is a TA-49, (still not a 100% sure yet) I'm cool with that, I'm glad I pulled the cover off to clean it or I never would of known & assumed it was stock. I'll assume for now that the torque converter is stock (I'll check later) if I can (but you know what they say about assuming). I was planing on getting the TT chip w/matching 42lb injectors anyway, but I'm glad I didn't order yet, just finding out about the turbo and all being different. Theirs already a test pipe w/a manual cut out & the rest of the exhaust is stock. Depending on what I do with the exhaust, I may put a high flow cat on with a nice 3" stainless exhaust. I just picked up a nice scan tool that I can read live/currant data for OBD1 & 2 , for tuning the engine right. I'M NOT going to be racing this car, & I would really like to keep it as original as possible, minus a few bolt-ons that were on the car when I got it. I just want too know what's on the car, so I can tune it properly & accordingly.
BUT, if smart !@$ pulls along side me at the red light revving his engine, I'd like to be the wolf in sheep's clothing that he never saw it coming, if you know what I mean.

The previous owner bought it for investment purpose & really never drove it for the few years he owned it, never registered or titled it in his name till I bought it either. It was from Wisconsin originally, I have the original window sticker, but don't know the 1st owners name. Thanks again for your input & advise, its very helpful.
