Rb25 Garrett Ball Bearing Turbo Upgrade

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.

PRO's

The turbo will bolt to your stock manifold.

Retains Nissan 5 bolt dump pipe.

Your standard wastegate actuator will fit.

Turbo still looks stock

Turbo has warranty, ending in Aug 2012.

CON's

You have to make custom oil and water lines.

Pickup from Bayswater, VIC

Price is $1760.00 - which is trade price. This is what we paid for it.

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.

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?

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.

      A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always!

      R33 Fuel Pump & Brakes after alarm swap

      Appreciate the correction on the "ground", that will make a huge difference to looking at this. That makes complete sense about AF70/AF71 which is what I had come down to being the issue, one of these. I'll have another look in the ignition wiring when I get a chance next week. I'll also make up a jumper wire for running that AF73 test.  ECU is fine, relay itself is fine, pump harness is fine and the pump itself is fine. I am going to upgrade the Walbro 255 anyway with a DW300 I have since I need to replace the fuel sender and I'm going to upgrade the FPR with my chasebays kit ready for new plenum/injectors/dbw, but I'll get this working first. That's why this is so frustrating.
