Rb25 Garrett Ball Bearing Turbo Upgrade

[Scotsman]

Hi Guys,

Selling an upgrade turbo charger for any RB25. Basically we've taken a R34GTT stock nissan housings (which are larger than R33 GTST) and put a Garrett TA34 core in it. The Garrett centre is a dual ball bearing core turbo with steel wheels. The housings have been machined to suit the wheels. The turbo has been tested on a car and is working 100%. This turbo has done about 50km on an RB20, but was just a little bit lazy to come on boost at about 4,000rpm and wasn't what we wanted on this car. But an RB25 would be perfectly suited to this turbo.

The work was performed by Rotomaster, Somerton VIC. I will post the turbo interstate - please ask for a shipping quote.

im after a turbo for my NEO 25, I spose this would be quite lagy as not a good match?

Though how much of a hassle cost wise are cuton oil and water lines?

how many KW did it make on the rb20?

It was never fully tuned on the RB20, as the injectors were also maxing out. We could only set the boost at 12PSI max before injectors were an issue, so it was made safe then road tested and wasn't what we were after.

Actually I would expect it to be a pretty good match for a Neo RB25 as it's roughly 20% bigger wheels than OEM using the OEM housings. Also it all bolts directly back on. Plus the added benefit of steel wheels = no more 12PSI limit, not to mention ball bearing vs plain bearing.

I think I did lines for around $270 using speedflow fittings, teflon braided -4 oil line and pushlock water hose. That's 4x lines and 2x fittings into the block.

So would this be expected to push similar figures to what a standard r34 hi flow would? 250-270rwkw

Yep - that would be the figure I would expect too. 280rwkw seems to be all most of the return flow intercoolers will push anyway, so there is no point getting a bigger turbo than this, as you will still end up with 270ish.

Anyone buying themselves a late xmas present?
