My new turbo. Can someone help me find the trim and specs of it.

[96eclipseawd]

I just bought this turbo from a guy that had it on an ls1 in a mazda miata. He used it for road racing at 7psi. Only has 3k on it.It is a T3 garrett a/r .60-compressor side, and a/r .81-v-band exhaust side. It is oil cooled with a 3" inlet- 2" outlet. Compressor inducer is 2.25" exducer is 3". I've googled this for awhile now and cant find anything. Compressor cover says a/r .60 m24 then it has an L in a box then a sideways B. Can someone help me with the trim, hp and max boost range, type of bearings? thx

you need to take covers off and measure the wheels. no one can help without that info

exhaust wheel diameters are 2.5" inducer, 2.75" exducer. compressor wheel diameters are 2.25" inducer, 3" exducer.

Anyone have any ideas on this? thx

How exact are those wheel measurements? There are a few compressor wheels that are in the ballpark, like a 50 trim, 57 trim, 60 trim, and 60-1. Is the comp. wheel 6 or 7 bladed? The hotside sounds like a T04 wheel, possibly a P trim. Are you sure the turbine housing is T3 and not T4? Posting some pics might be helpful as well. Here are some exact measurements of compressor wheels:


50 trim - 2.12"/3"
57 trim - 2.23"/2.95"
60 trim - 2.29"/2.95"
60-1 - 2.32"/3"

Here's a list of current turbos, what you have may be older. The closest thing looks like the 6052E, which is a 60-1 with a 76 trim turbine wheel.

To calculate trim of a compressor wheel use this equation: TRIM = (Inducer / Exducer)^2 X 100

(2.25/3.00) = .75

.75 x .75 = .5625

.5625 x 100 = 56.25 Trim

That is if your measurements are correct like stated above.

The exact measurement is 2.32"/3" compressor wheel. so it's a 60-1 trim compressor wheel, and an 76 trim exhaust wheel? The turbo looks exactly like the one in the precision link above, it has 7 fins, and the little bit of white paint on one of the fins. Ill load a bunch of pics later today.

Yep, sounds like a T04B 60-1 P trim in a .81 T4 open hotside. Prepare to wait a looong time for boost. There are alot of turbos out there that spool alot faster and can make alot more power these days.

 

[96eclipseawd]

It has a t3 flange, and vband outlet. What rpm would I be looking at with full boost? Im trying to get 500hp to the ground. The engine will be built, and probably .40 over w/ 280s, fmic and a 63mm throttlebody. Would it help if i stroked the motor to a 2.3l to spool it up?

 

[brainlessher0]

I would buy a faster spooling turbo before i stroked my 4g63... IMO

 

[96eclipseawd]

What would you suggest to get, if I sell this one, that'll be capable of 500 ponies, this has 3k on it with zero shaft play. How much lag should I expect with this one?

 

[96eclipseawd]

Here are the pics of it.

That's NOT a t3 flange. It is most definitely a t4.

 

[96eclipseawd]

Does someone have a spool time on this thing. Say if i have it set for 20psi. Because if it's like 4k, I can deal with that to have it hit hard

 

[Steve93Talon]

In that hotside, with the antiquated 60-1 compressor wheel, full boost would probably be somewhere in the ballpark of 5500+. Fully choked out on race gas you can probably crack 500whp but you'll be working hard for it. There are literally dozens of turbos out there that'd spool 1000 rpms faster while making more power. If you're looking for bang for the buck, take a look at a Borg Warner S360 non-extended tip. You can put it in a bolt-on hotside or a .70 T3.

@#$%. I appreciate the input man, I'll just sell it and try to find a different one. thx
