how does a T3 turbo compare to a T2?

[JuXsA]

Whats the difference of a T3 turbo to a T2? I might be able to buy a T3 turbo to use and I just want to know if its any better then a garret T2?
What are the specs on it.

Thanks

[Frank]

A T2 turbo is basically a T3 50trim?! I think. So it wouldnt be better.

[JuXsA]

reason I ask is cause I think I can get a good deal on one. But since I already have a T2 im not sure if its worth it or not. Just trying to figure out how much better.

Here are the specs I just have no idea how the hell to read it.

T3
Compressor housing A/R .52
Exhaust housing A/R .48
Compressor inducer 45 mm
Compressor exducer 60 mm
Exhaust turbine diameter 48 mm

T2
Compressor housing A/R .42
Exhaust housing A/R .48
Compressor inducer 42 mm
Compressor exducer 60 mm
Exhaust turbine diameter 48 mm

I just have no idea what the hell any of this means.


Its for sale locally and its been rebuilt and not used.

It looks like a smaller compressor on the T3 exhaust side...almost like a T3/T4 hybrid in reverse.

I think the T2 is going to be WAY to small...or it'll be comparable to the TE04, but I don't have the maps, so I can't back that up.

I have no idea what you just said:D

Juxsa,

When you say T2 and T3 are you referring to Garrett's version or Chrysler's version? It is a bit confusing for most because they both use the names T2 and T3 but they mean completely different things.

Yeah, what he said, T2 vs. T3 Garrett turbo or Turbo-II vs. Turbo-III Chrysler engine combo?

JT, can I use that information to update my Turbo FAQ here?

Thanks

It looks like he is talking about the physically smaller garret T2 turbo, not the T3 that came on TII vehicles. I don't think the turbos on TIII vehicles has anything to do with this.

JT,

Nice link. That should explain things for him.

chyrsler turbo 2 versus chyrsler turbo 3

I read that link. so it has a 3mm larger inducer. I still have no idea how a bigger inducer helps if the exducer is the same size as a stock T2 garret.

The matrix at the bottom lines up the Garrett and Chrysler combinations. the real problem with using a Chrysler Turbo-III turbo is that it has the standard garrett rectangular 4-bolt mounting pattern as opposed to the Chrysler trapezoidal 4-bolt mounting pattern used on the Turbo-I and Turbo-II cars.

I's just stick with the Turbo-II turbo

lone wolf says they can make the stock exhaust mani work with the standard T3 bolt pattern. I talked with them the other day. They just drill another hole or something like that

[BadAssPerformance]

If you have a good Turbo-II turbo, I wouldn't think it would be worth the co$t or troublr. Just my $0.022 ...

[JuXsA]

im building a new motor. As soon as itsdone at the machine shop I am going to pull the 2.2 out of my car, take the head off, put a ported exhaust mani and a T2 intake on it and then bolt it on the new 2.5 Then I will be sticking it back in the car. The turbo is cheap, fresh not used rebuild, with a .63 AR turbine housing.

Putting it on my car is not an issue. I just want to know how much better it is over a Chrysler T2 Turbo. How many lbs per minute is the compressor on the Chrysler T2 Turbo and how many lbs per minute is the compressor on the Chrysler T3 unit and would it work well on an 8v head with a ported exhaust mani.

For instance the compressor wheel on a true super 60 turbo is 35lbs per minute.

[BadAssPerformance]

Good question, anyone have any flow numbers on stock turbo compressor wheels?

btw, now that you mention it has a .63 A/R exhaust housing, that makes it a totally different story... I beleive it was the old Mopar Performance 'Turbo Plus' turbos that were basically a stocker with a .63 A/R exhaust side.

With the .63 A/R housing, if it is way cheaper than a Super 60, I'd say go with it :thumb:

[JuXsA]

yeah, I just figure turbo size by lbs per minute. thats the only way I know how to figure it out.

Doesn't the Chrysler TIII turbo have a different style flange?

[Phreakish]

yes, it has the standard T3 flange (T3 NOT TIII) that most other T3 type turbos have, like the ford supercoupes...

Best I can find, its somewhere between 30 and 34 lb/min - but thats not 100% reliable...

Super Coupes were supercharged. The turbo coupe was turbo charged, but +1 regarding the flange style.

[Phreakish]

drrr.. I'm not a phord guy :) lol - the turbocoupe then :D They used the same bolt pattern and turbine size IIRC
