Turbo Identification

[mawzy]

Hi all. Just wanting to know if anyone recognises the make of this turbo, by it's design, or markings. Was told it was a rebuilt one with garrett parts but can neither confirm nor deny. had the housings off an the wheels are in perfect condition. No play in the shaft and spins freely.

Also what's people's thoughts. I initially bought it to put onto an rb30det, long story short I ended up putting 25det neo back in the car. But when money allows was still thinking of using this on my 25, But I sorta think this will be too big and quite laggy. The other mods that would follow with it would be front face plenum, high rise exhaust manifold, 60mm hks style waste gate, 650cc injectors, and suitable after market computer. I have all the parts except computer. Anyone hazard any ideas on how responsive/powerful this setup will be? Thanks for any help, or input.

Yeah looks pretty big! Hard to tell from the pics how big it is cos there's nothing to scale it to. I'm gonna hazard a very loose guess and say it's an apexi turbo. That compressor housing doesn't look very Garrett/hks/Mitsubishi, but does look similar to other alexi turbos I've seen. Check the turbo all over for part numbers and chuck them in to google, see what they come up with!

Do you have any specs? I.e. Exhaust flange size, exhaust wheel size, compressor wheel size etc? That should give ya an idea of how laggy/powerful it'll be.

I'd recommend nistune daughter board, soo easy! Just send off your stock ECU, give em some time and then you'll have a tunable ECU that is cheaper, more effective and allows you to retain factory driveability and all the sensors, compared to other computers.

That split pulse exhaust housing is pretty good too, should spool up a little quicker than normal.

Good luck dude!

Ahh sorry, it's a t3 entry flange and the only identification markings on it are ar .84 on the exhaust housing and ar .70 on the compressor housing with m24 and the lil stamp that looks like a fudged cross. The 2 middle photo's show this. Thanks.

you sure it's T3?

[mawzy]

Yeah positive. The exhaust manifold I have is t4 flange, so had it changed to t3 to suit. Anyone hazard any more guesses. The only turbo's I've found with 6bolt exhaust flange like that has been a garrett gt32, but it's a diffrent looking/size turbo altogether. Would appreciate any help, thinking of selling this and down grading size, if people think it's too large.

Any numbers on the centre cartridge? Near the oil feed. A tag of some sorts?

Its a TO4E with in .84 split pulse turbine housing with a Cropped turbine wheel. I can't see your comp wheel, but they comes out of factory with a 76mm 56T tall wheel that is rated to about 500HP.

Its very laggy even with standard turbine wheel, its going to be even laggier with the crop. I'd say it will hit 20psi around 5500RPMs with plenty of torque.

Thanks for the input. No there's no numbers, or tags on the centre cartridge. I've also added a picture of the compressor wheel. And thanks Hypergear, any idea on the make?

[The Dan]

Early Garrett stuff...and yes T04E is the turbo.

Journal bearing too so laggier than normal especially in that frame size. These are approx 15year old technology.

You'd be better off with a GT3082R or 3582R

Looks like a 82mm comp wheel. Its a custom build turbo trying to archive 600HP. The GT3582 would be lot more responsive. Its going to be very laggy to run on a RB25det. Probably good for a 3L+ engine.

Looks like it has a Garrett GT wheel in there though rather than the old T04S 7-blade ones

So this is better? I was told it had been rebuilt, but again, no real proof to prove either way.
