R32 Gtr With R34 Turbos

[No.96]

G'Day

I've bought some R34 GTR Turbos, I've heard about the place that they have ball bearings against plain bearing in the 32's.

Do you need to restrict the oil flow to the turbos?

Thanks

Anyone?

The reason I ask,

A guy I know put a 25 neo turbo on a FJ and he had problems with oil smoke from the exhaust, apparently to much oil flow/pressure for the turbo. He was told to restrict it and it fixed the problem. "A common problem with this upgrade"

I was wondering if I would face the same problem?

However, I would of thought if it was a problem there would be a few complaints about it, as it is a fairly common upgrade.

Thoughts?

I would assume it would be a different oil pressure / system set up on the RB25DET (Neo 25)...

I know the R32 GTR's ran factory Garret T28 Turbochargers... Should be the same as the standard R34 GTR ones (Clarification Needed) but R34's got the steel internals = it being a stronger turbo.

Should be just a straight bolt on fit... No need for restricting, cuz you definatly want oil going to the turbos in a GTR.

Best check with your mechanic.

The R34 turbos are suppose to be ballbearing steel blade turbos so the oil restrictor should be a .035" for the R32 and R33 journal bearing turbos the restrictor should be .06". I am doing over my lines with braided ones and I am going to be putting restrictors on my Nismo turbos.

I have an R32 GTR with R34 turbos. The turbos are already fitted with correct oil feed restrictors. I just bolted them on about 2 years ago without any changes. They spin up much quicker (less lag) Im really happy with the mod. The car is much nicer to drive and pulls harder in higher gears. Also its only the N1's that have steel wheels

Do you need to restrict the oil flow to the turbos?

Yes. You should use the R34 oil feed banjo bolts as they have the appropriate restrictors built in.
