Hi there,

 

I've just bought a second hand turbo and need some help identifying what engine it's from. There are a bunch of numbers on the plate, but nothing seems to return when searching for the info on it.

 

The plate reads Garrett, but there are castings of both Garret & Nissan Motor on the housing. I've added some photos, any info would be much appreciated.

Give photos of the compressor inducer, turbine exducer, turbine inlet flange, casting marks on the comp and exhaust housings.

Write out the numbers you can identify on that core tag. We can't see them clearly enough on the photo to be sure about anything.

Measure diameter of comp inducer, turbine exducer. Measure OD of comp wheel and turbine if you can. Verniers are cheap.

I'll try my best, first turbo I've ever bought so apologies if I don't know all the right terms or bits.

The plate reads:

14420-W3460 Made in Japan Garrett

410581-11 RA 0235J

In addition, on a flange below that reads 'RSM5'.

Inside the exhaust port is either '10' or '01' and a 'V'.

On one part of the turbo it has a cast which looks like '2-9'.

On the part which has 'Nissan Motor'there is also a 4.

All,

I think I've found the answer - seems that although the plate doesn't have zeroes after the dash, the model number is actually 410581-0011. This would make it a TB0306 off a '81-'87 280/300ZX.

Some details on the parts numbers here:

And a similar looking turbo noted here:

If anyone has thoughts on these units (e.g. how reliable they are, known issues, etc.) that would be much appreciated. I was looking to use this on a MK2 Ford Escort - either with the native engine or using a Zetec/Duratec.

So, the 0.48 on the turbine housing is the A/R of that housing. Which is SMALL.

The dimensions you've given are not super helpful. The exhaust inlet flange appears to show 55mm on your verniers. That's neither the expected 50mm of a T2 housing nor the expected 58mm of a T3. Can you measure the other dimension across it, and the bolt pattern?

The exhaust housing is definitely Garrett, not Nissan. The dump pipe flange is for Garrett style dumps, not Nissan style.

The compressor housing is Nissan. It may not actually belong to that turbo originally. It may be a Frankenstein, cobbled together.

The measurement across the outside of the compressor inlet is not super helpful. The inner diameter is the useful one. We can see from the verniers that the ID will be only ~55mm and that it hasn't been machined out as part of any highflow work. The actual inducer all the way down at the compressor wheel would be another 10+ mm smaller than that.

Sadly, I'm not familiar enough with dirty old Nissan comp covers to recognise it. It is definitely really old - Nissan comp covers have had flanged outlets for ages. I can't even get a handle on physically how big the turbo is. Wide angle lens distorts percpective.

Hopefully someone else can use the information here.

Ah. I see your response. 280Z would indeed be "dirty old". But....it can't/won't fit both a 280 and a 300. The 280 was an L series straight six. Any turbo for those would be a single turbo, needing to be T3 sized. I guess TB03 is in that ballpark. The 300Z was a VG30 V6. The turbos were single, but obviously the mounting location would be quite different on a V6.

Thanks GTSBoy, don't know much about the 280's or 300's - just going off what the Google results are.

Thanks for the link, there seems to be some reference in there to older 300ZX models so maybe this is on the right track.

I'll measure the other dimension of the exhaust outlet and the compressor inlet ID and get back to you.

      R33 GTR running -9 with no tune

      By Duncan · Posted

      Sounds like you've got an interesting adventure ahead here with local support if you have trouble! My guess is that, unboosted, you will be OK with a small upgrade like -9. What will happen is that once the stock ECU sees more airflow than it expects it will add a heap of fuel and pull a heap of timing to be safe because it can't understand how it could get that much air without there being an issue. You will see clouds of black smoke and it won't pull hard through the midrange and top end. So, overall it will be a bit frustrating but should be OK. If you are still nervous set the base timing back 2o through the CAS, but it will be even more sluggish everywhere. As said above through...this is not my guarantee your engine won't be blown into a million pieces, leaving you looking for very hard to find parts A better idea is get a computer with logging ASAP, wire in a wide band O2 sensor and a use remote tuner. I've done multiple cars this way and while it is not as good as a specific tune on a dyno they can get it 90% right. I'd suggest if you can afford an R33 GTR these days you can afford an ECU and tune. And if you can't afford that you sure won't be able to afford the rebuild if it goes bad in the meantime,.

      Yeah it would be nice if someone took the time to put that sort of information together, but there are a lot of variations in looms. I think you are making this way hard for yourself if you just want to get it running....sourcing an SR20 with the right wiring will be a billion times easier than matching the RB loom to an S15 chassis. If you do end up going this way, you just need to trace every wire in the loom with a multimeter, 95% of them will go to a location you can confirm at the ECU.....and then post it up for the next person who needs it

      Coolant leak?

      By Duncan · Posted

      Just top it up with water, and keep a general idea of how much you added. It is normal for water to be pushed into and pulled out of the reservoir through the cap, and it should not be more than half full or it will be likely to overflow when hot. Any decent mechanic can do a pressure test of the cooling system to confirm if you have a leak. Keep in mind if it is only leaking a little and when hot it may well evaporate before you see it hit the ground

      Coolant leak?

      I'd ask the shop what they used and use that. Mixing coolants is sometimes OK, sometimes not, and you have know the details of each coolant to know whether it's a good idea or not.

      Is it alright to top up with just another green coolant?
