Default Turbo ID please

Got the silver NA today that I bought off of Vito. Pulled the turbo, lines, manifold, downpipe and full FM 2.5" exhaust. That will go a long way in building my SAAB exhaust. Just need to remove the cat and add in a section of pipe to accommodate the longer wheelbase but most of the tubing is there plus a free-flow muffler so I'm happy.

As far as the turbo goes, it was called a FM2 kit in the ad so I was hoping for a 2560 or at least a 2554. Looks like I got neither.

Hot side is AR .49 M4. Cold side is AR .48 M24. Same specs as the SR20 T25 that I have but that one is a M10 cold side. It has a factory Overhaul tag on it and the shaft play is zero. Much better than the "fresh overhaul" that I bought on Zilvia.net.

Wastgate is marked 91-092 10 443700.1 so would that be a 10 psi can?

Ended up selling the car for $900, he paid the $308 tow bill and I got the above parts and made $400 and I didn't have to haul it home or part it out so I'm not even mad.

So, what do I have?

Is it t25 flange?
How is it your sr20 turbo is .49 turbine?? I'm pretty certain all t25 sr20 turbos are .64 ar.
Best thing I can say is to measure the diameters on the wheels.

Same thing stamped on both. Wheels look the same when sitting side by side. Both are T25 flange.

Not much help, but i searched for hours on that m24 trying to find out if it was a model # or something for my own turbo. Turns out it's just a designation of what alloy they used for the turbo itself. Best of luck!

Is there a serial number or part number on the CHRA?

See if the number crosses here: http://www.turbo-product.com/Nissan/

I used to have two Nissan OEM turbos, one small T25 from a CA18DET motor on a 200SX (on the right of the picture) and a bigger T28 from a SR20 motor on a Nissan Pulsar GTI-R car (on the left of the picture) and both comme with a 3-bolt flange on the compression side, and as you can see the T28 also have a 2 bolt flange on the intake. The adaptators on the T28 are aftermarket ones

CA18DET turbo.

It's small because only half of the turbos used on that from the factory.

I believe it's the same thing as the SR20 turbo, just with tiny A/R housing.

What do you think upper end of efficiency be? 180-200 whp max? It's for the SAAB.

is the SAAB getting a 1.8L?

I'd expect fast as **** spool, tons of mid range, and nothing above 4-5K. Probably peaks at 150-160rwhp.

the SR20 turbo already dies above 5.5K, and that has a .86 A/R turbine housing.

Yes, the SAAB is getting a stock 94 1.8. I have two of these .48/.49 turbos now. If I was baller I'd twin turbo it with a pair of them but I don't see a reason to do that.

Might just sell both and buy something else.

how'd you end up with two? the SR20 is a .86 turbine and .64 compressor housing; you suggested you had an SR20 turbo.

the above dynos are the actual SR20 turbo. You have two CA18DET turbos it seems.

The first was sold to me as a rebuilt SR20. The second one was on the crashed 92 that I bought and was indicated it was a FM2 kit so I assumed it was a 2554 or 2560. Maybe I should just twin turbo it with the two little guys.

If I thought it had a chance in hell in not sucking I'd consider it. I haven't built my manifold yet, have two sets of water, oil lines and fittings, all of the manifold components except for needing one more turbo inlet flange.

I have seen them and I wonder:

Why aren't they on a car now?

If they are so great why hasn't anyone else done it?
