I don't think John even has a name (or number) designation for the turbo that I am using. I CAN tell you that Lee Thompson has used this turbo in the past with pretty decent success (I am not sure what he is using now). I was told by John that this turbo uses a 65 lb per minute compressor, mounted in a ported stock compressor housing. It uses the stock type center section, but has a much larger Precision A/R .63 exhaust housing, along with a P-trim turbine. The stock downpipe will NOT work well with this turbo, as the turbo outlet is 2 5/8 inches in diameter (compared to the downpipe, which is about 2 to 2 1/4). I have also found that the stock style wastegate is not wanting to work very well, as boost creep is unavoidable, which is why I'm going with a Deltagate. John recommended 55lb injectors, but to avoid mods to my ECM, I opted for Lucas 50's. I can also tell you that the stock convertor is not nearly enough. John recommended a 3200 RPM stall, but I am going to try to get by with an orange stripe convertor (about 3000 stall). John also said that this turbo will flow over 1000 cfm and should be good for about 600 HP, if all the other pieces are right. Obviously, this turbo is not going to be the best choice for everyone, but I tend to go a little overboard sometimes.
This is a reply that 1984grandnat leftin my question on turbochargers. The John he speaks of is from Limit Engineering. I hope this helps it made me think twice about buying a ta-33c. I'm still undecided as to who to buy fromm and what turbo I would like to go with so please let me know what your buddy decides on.

ta-49
It's unbeleivable on how fast the spool up is. I was used to a stock 87 turbo and it was a big gain from an 84 turbo. But I can't really say about a ta33 never had one. But I love the ta-49 hope you have the same good luck that I did, you'll love it mucho HP. Tony

What he said, the turbo spools a lot faster and makes a huge difference. Just make sure to turn your boost down when you first intall it or you could be like men in black and have to replace components. Went to about 30 #'s of boost right now and blew the air breather hose in half.....

Will the stock adapter work? What about the Wastegate?

'87 turbos
I put a '87 stock turbo onto my hotair, it fits just fine, but you cannot just "reclock it" and stick it in.
First of all, you need the bottom turbine peice with the two bolts sticking out from a hotair turbo - to fit the stock bracket.
It's easy enough to clock it by just looking at the angles on a hotair turbo.
Secondly - There must be cutting!!
I can't remember measurements off hand but its a good idea to have a vice, or a big c-clamp with a bench, a hacksaw, measuring tape, etc.
You need to cut the compressor outlet, and the intake adapter so that the turbo, when seated on the bracket, will just barely have a gap between the cut intake adapter sitting in the intake.
Then you just use a peice of silicone hose and clamp them together. Works great - 17 PSI so far!
Heres an idea of how it looks after you cut/clamp:

Notice it doesn't stand out very much, so it looks decent.

Notice the throttle body gets turned about 25-30 degrees.. hmm Well there are adapters available but I beleive they come with a complete kit for a intercooler so that'd obviously be another project.

This shot you see the hose is obviously short, the two clamps around the hose - the turbo isn't going anywhere because its bolted onto the stock bracket.

turbo adapter
I have the adapter to straighten up the throttle body.
Email me if you need one.

Clocking the turbo & TB
You can buy an adapter to turn the TB back upright. I bought one from Lee Thompson. He had a post on here a couple months ago about those adapters. I think they were billet aluminum and the were around $60 and worth ever penny of it. If I can get my son to take some pics I will send a pic of my hot air with ta-49 and cold air big mouth. Tony

OK
HEY THERE....First off never use the intercooler hose to connect the turbo and adapter piece. i was one of the first people to put a 87 turbo on a hot air but cutting as JayLashua did. after 20 psi of boost that rubber gets so hot it starts to melt. after time u have a creamy ball of rubber that is nasty as hell and leaks like a siv. if i had a choice i would have bought a ta-33. i am having a cutom piece mad the fix this probelm. i have a guy working on the piece all week so i will try to get some pictures when i get it and start to put the car toghter. Buy a Ta-33 and save your self the trouble i sure would if i was back when i decied.

hey
the reason it doesnt melt on your 87 setup is because one the fans are blowing right there at the outlet of the turbo and second its not all squised down in the back with no air flow or anything. the exhaust and stuff is right next to it. if u dont believe what i say ask WAY2QWK he and i have done this and he will tell you the same thing, it does melt.
also the outlet temps on our hot air cars get alot hoter the the oulet temps on the 87 setups.
