Recomendations on new turbo

[Rex 2.0]

I was debating whether or not to rebuild my turbo or buy a new one. After looking at prices I decided to go with a new one which I can get for about $700 vs having my current one rebuilt and balanced for $350. I can also get rid of the coolant lines for the turbo if I replace it.

This is the one was thinking of getting

I was going to go with the .63 A/R

Any thoughts or suggestions

You may want to consider the .48 a/r for the hotside. What are the specs on your current turbo?

I think I saw a garret t28 of a jdm sr20det for like 300. There BB and spool just as fast as a t25 if not quicker. Plus it will bolt up to your manifold.

It is however, also watercooled.

cold side is .60. I think the hot side is already .63. I thought I had rex's write up saved but I can't find it. It is out of a thunderbird turbocoupe with a 2.3. possibly 87 - 89.

Why do you want to eliminate the coolant lines? It's not a bad thing to have it cooled. The one on my Legacy has both coolant and oil going through it.

I was also thinking if you want to eliminate the coolant lines then it probably wouldn't be a bad idea to get a ball bearing turbo, but that's $400 more than what you want to spend.

Something I found about pro's and Con's

Longevity life of the turbo. Will be greater with a water cooled chra.

Pros & Cons:
Pro of the water cooled is longer life
Con of the water cooled is lines / issues with leaks / clutter of the bay / extra money to install

Pro of oil cooled is cleaner bay / less lines / no problems as long as you follow the general rule of thumb about letting the car idle after hard runs.
Con of oil cooled is less life of the turbo vs a water cooled.

You already have the coolant lines there, and IIRC at this time they are not leaking, so its not a bad idea to keep the water cooling setup.

I am not really against the cooling lines but it would be nice to have less crap in my engine bay. If I can find a turbo that is water cooled for a similar price I might go with that but I am still looking.

ok, makes sense.

Just hearing this thread makes me want to swap even more on a site note. But I would also say stay water if you can. Oil turbos can cause a lot more problems if it goes faulty a lot faster as well. Of course it sounds like you replace/rebuild yours every so often so that may not be an issue but personally I would leave the oil in the car and not running all over.

Pat, one other thing that I thought about as far as the oil consumption you have, is to look at the valve seals. I'm not sure how easy that is on a quad or how often they go bad, but it's worth a look since I'm assuming they would be similar to mine and be replaceable while the head is still on the motor.

I only suggest that because if the turbo was leaking a lot your charge pipes and IC would be soaked with oil. So the only other two items that could cause heavy oil burn would be valve seals and rings... and well rings are the worst case scenario, but with lots of boost you could have blown out a valve seal. Not sure how well those are made to withstand that.

[Rex 2.0]

I have done several compression tests and they always read fine. I also have what is a block leak tester. . That checks fine as well but I don't know how accurate it is.

I have been contemplating rebuilding the motor this winter as well. Rex gave me a gasket set with the car when I got it but I don't know if it is complete because it was opened and could have lost one in the boxes travels. I have to find a contents list and go through it.

You have a T3/T3, .48 A/R turbine, 60 series compressor, non-super 60.

Buy the one on bstuff cause its perfectly sized for your car. Buy the manifold too if you'd like since that ones an external wastegate.

You will likely be getting boost at 3000-3500 and it will come on quick.

[3400beretta]

Have to disagree with you there Dusty ^. That turbo on bstuff is too big for a stock quad. This isn't a race car.. he'll be lucky to see full boost at 4k rpm with that turbo. Not too much fun on an already torque-challenged engine if you ask me.

Pat, when are you seeing full boost with your current turbo?

Pats turbo is not a t3/t4, im nearly 100% positive. Its much smaller

[3400beretta]

Barry, might wanna re-read what Dusty wrote there man...

[Rex 2.0]

IIRC it is a t3/t4. The numbers sound right. I though I had rex's part list saved from the old behind the wheel on here but I can not find it.

I currently get full boost around 3000-3500rpms. It does not take long at all.

I did not see a manifold on bstuff and the only turbo I saw was from 90hogtz and I would probably have it rebuilt first because i do not know the exact condition of it and it puts me back at the price of a new one.
