Outer Limits 4x4 Board

i have a garret turbo sitting here that i want to put on my td42 i want to no if its to small. it is a t25 of a skyline. have been searching for a few days now getting info but cant really find anything on this turbo for this motor fit out.

We'll need housing sizes - but i'd say it will be too small. Probably would work up to about 2500RPM before it bottlenecks.

okay it says on the exhaust side .64 and on the inlet side it says A/R 60. not to sure if this is what your looking for. thanks coxy321

Like i said, it would work, but it depends what you drive and how you drive it. For low RPM work (crawling, poking around forrests etc.) it'd be ok, but for higher RPM/towing or any future power development it'd be a waste of time. Saying that, the flash upgrade Garrett BB units are a T25, so upgrading in the future wouldn't be that painful.

Any numbers on the plate in the centre core of the turbo? Or pull the housings off and measure compressor and turbine wheel sizes.

it'll make boost thats for sure.

being a skyline turbo it will have a T3 flange, get a manifold with a t3 flange on it and fit your turbo. If it doesn't suit the way you drive there plenty of T3 flanged turbos that will fit in its place. A number of them are listed as direct replacement for a skyline, so it would almost just bolt straight on.

thanks for your help everyone. its bolting to a denco himount so it should be sweat.

You never mentioned what Skyline it came off. For all we know it might be off a GTR twin turbo....

i talked to the bloke i got it off an he said it was off a nissan 300zx twin turbo. my mistake.

Twin turbo = half of 3 litres = NFG.

Sell it and get something bigger. It will be making boost at idle, and will start choking up at 1500RPM.

Not worth the effort mate.

300zx turbos are a great turbo for hilux 2.8s. they dont have the push for a 4.2. an australian s15 (98 i think through to 2006 i think) silvia has a t28 on it that is the closest to perfect youll find without getting one made (i.e. dzltec) but they are rare and will prolly cost you just as much as getting one of dzltecs units.

When i was hunting a second hand turbo, i found HEAPS of info on the various factory Nissan units, as well as the various differences they had between year and model (Skylines, Silvias, 300's etc etc). There are a few factory Nissan turbo's that will do the job, however finding the correct one (as in "correctly identified") can be hard, and also finding one that isn't flogged out can also be an issue.

If you're hunting a second hand one, maybe try a few importers ( like http://justjap.com/store/home.php or similar), or hunt for a locally common unit like a VL/R31 turbo. My unit is off a 300ZX single turbo - but i've found it bloody hard to find another, plus they came with a ceramic exhaust turbine which is limited to about 12psi before they self destruct.

Have fun.

Did you not get yourself a disco potato in that group buy you did months ago coxy?

A VL/R31...is that a ballbearing unit and what vehicle is it off?

There were 1-2 people that did, but i didn't have enough coin at the time to get one from the goup buy.

VL = Holden Commodore, 1986->1988. They used a Nissan RB30E/RB30ET 3 litre inline six cylinder.

R31 = Nissan Skyline, 1985->1989. RB30E engine.

The Aussie RB30ET's were a plane bush bearing unit, however there are many, many aftermarket units available. The VG30DET (300ZX single turbo) came in both plane and ball bearing types, however there isn't really any documentation/reference as to when/what/how certain cars had the BB turbo.

The VL (Nissan T3) turbo's come up on eBay often, some fully reco'd, others high-flowed etc. Its just a matter of waiting for the right one. Either that or troll through some of the fullysickboys forum's for sale sections.

Once i get my car tuned, you're more than welcome to come and have a look and test drive.
