RB26 Rebuild

GTRJazz · Post by **GTRJazz** » Tue Apr 10, 2007 1:52 pm

Not having much to do over the bank holiday :roll: I thought it worthwhile to give my R32GTR engine a refresh. Good job I did the shells are looking quite worn after running over 400 bhp for a few years. Before I stripped the engine it made no noises and had good oil pressure.

The rear of the pump

Oil pump

Flywheel showing no sign of drag launches

Crank pads not worn

Big ends showing wear

A worthwhile exercise then, should be rebuilding with Tomei bearings, Jun pump and drive, Tomei sump baffle or big capacity sump .

The shells may be looking worn, but knowing the way you drive your car, the rest is looking very good (albeit that I know sweet FA about cars :thumb: )

I've posted the photos for you Paul as it may garnish more interest from others, hope you don't mind. I take it you have done this before on a GTR?

No not at all

I have rebuilt my RB26 a couple times now due to pushing the boundrys of what standard parts should go through. The last engine I put together for the Black car was around 1K including Tomei sump baffle, R34 GTR turbos (

OK Paul - what you doing next weekend and how much do you charge for a refresh? :lol:

Good thread - I'm going to be following it with great interest.

Its getting the parts together that slows the job down. I have ordered Tomei big end shells using the grading system but will not be able to check the gaps till they arrive, you really need to order a size each way as well. Still not 100% what oil pump to use. My old Nismo pump next to a standard oil pump. Notice the different number of pump gear teeth, not just a spring upgrade.

Well all is going better than expected with the parts order

so far from Greenline

TOMEI Micro Finish Conrod Metal STD1 RB26DETT:
TOMEI Oil Pan Baffle Plate RB26DETT:
JUN Oil Pump Drive Collar R32 GTR: (Last one in stock)

For the other parts the local Nissan main dealer, Oil pump part number 15010-24U01 (R34 NUR, N1)
Main bearings, bolts.

I think its better to use the standard main bearings as the uprated shells are soft to protect against surface peel
This means that the bearing coating on the thrust washers is also soft and will not last as long.

How do you get on with Greenline Paul? When I've had to get stuff direct from Japan I've only ever used another firm who have been excellent.

If the Nissan dealer is slow with the N1 pump you may want to try Andy Coulson ( R32 Combat) as I think he still has a new one.........

Glad the build is going well for you.

They got back to me the next day after my EMail which is better than some, I will let you know how long they take to turn up.

As the parts will not be here for a while I have started to prepare the sump for the Tomei baffle. The short drive shaft has to be removed to allow the oil return holes to be drilled out to a more useful size. With the standard set up the oil from the whole rear of the engine has to drain through holes of only a few millimetres, a lot gets trapped in the back of the sump so staving the oil pickup at the front.

Dead link Paul.
