Hey all, after I replaced the A/C compressor, I noticed that there is a leak coming from the turbo after looking at the air intake and saw that it has a light coating of oil on it. Then I saw white smoke coming from the turbo area and the back of the tail pipe. There is no strange noise coming from the turbo, so I know that the turbo works fine. I know that it will be a pain in the neck to get to the turbo, so I decided to get it fixedby a professional. Does anyone have a cost estimate of someone replacing the turbo seal?

 

OK, nevermind. Anyone know where i can find a diagram of the turbo seals?

 

OK, scratch that one as well. I'm just going to buy a new turbo and have some guys that I know install it for me. Anyone know where i can get a new turbo at a fair price?

 

Bump.

 

Anybody know the specs on the on the turbo? Found one online that might fit my car and need to know if it fits. I got the specs on the turbo that I found and here it is:

100% brand new
Capable of boosting horse power up to 300+ BHP
High quality material, cast housing with durable steel
4 bolt exhaust flange
Standard T3 5 bolt downpipe flange pattern
Intake inlet & outlet: 3" & 2"

Compressor:Trim: 55
A/R: .5
Inducer: 50.5
Exducer: 76

Turbine:Trim: 73
A/R: .63
Inducer: 65.5
Exducer: 55.9

Really need to know if it is compatable with my car.

 

Ok, have found turbo chargers for less what the dealership wanted ($1200 just for the turbo). Found new turbos online for about $650-$750 plus tax and shipping. The only thing that is holding me back is where can I find the manufacturers label on the turbo on the car. The turbo is made by either Garrett or Mitsubishi.

 

I hate to see one-way conversations here and like to help out the most I can. Unfortunately I don't have any turbo experience.

Have you checked out TurboBricks | High Performance Volvo Club You should be able to might be able find your answers there.

Good luck.

 

There should be a plate on the turbo it self like a vin plate, or thats what I've seen on other turbos( not sure on volvos)

 

my s70 has a Mitsubishi turbo

but thats a 98 not a 91

 

pretty sure a 91 740T has a mitsubishi td04h, but not all td04 are automatically a bolt in, you want one specific for a volvo 740/940.

For a 1971 740T, the turbo was volvo PN 3517646, which has been superceded by the 'exchange' PN of 5003713 which is $711 plus a $250 core charge at Tascaparts.com.

that would be a FACTORY rebuilt turbo. you can find aftermarket rebuilt ones for *maybe* $100 cheaper. caveat emptor.

 

I second the Mitsubishi TD04H. I've seen a 92 with a Garrett, but I think that it may have been swapped from an older car. Volvo's turbos have an internal wastegate and a funny gasketless flange. I think the TD05 on my car interchanges as well. It's a little bigger. Volvo went to a smaller turbo for quicker spool up. I'd just get on specific to your car.

 

as I understand it, the garretts had a little more top end power but with more lag, while the mitsus have faster spoolup giving you better low end torque.

 

Well, I did find out a while ago that my turbo is a Mitsubishi and all I need to do is order one and put it in. That is when I'm not at work or helping my brother work on his car (which doesn't run).

 

Before dropping a boat load of money on such a tiny turbo, consider having your existing turbo rebuilt. Doing it yourself is about $120 in parts or you can have it sent off for a bit more. I get my parts from G-Pop Shop They are extremely helpful by email.
