Rb26 Dett Querys

[Faircall01]

Hey guys,

thinking about buying a R32 GTR sometime soon and i was wondering if there was anything i needed to know about RB26 motors, like if anything is known or prone to breaking. i.e any common faults or issues.

thanks guys.

my rb 26 seems bullet proof. i guess have to be weary of the turbo's can be expenisive to replace.. if they are the ceramic type. Only really good for about 100,000.

Injectors could be cleaned etc.

Check the seals on the engine, i needed to replace some of mine.

if it is just in standard from... engine internals should be fine and strong.

I'm sure other GTR owners would agree.

Thanks mate,

do all the rb26 motors in r32 GTRs have ceramic turbos

[KBNR32]

only 93 and 94 vspec have metal

Do they ? Have you ever seen them ?

[sav man]

Only N1's have metal, every other GTR (v-spec included) are ceramic.

[Morgs]

The pair I got here off a Vspec are ceramic?

[cowie165]

Ben I thought it was the 1990 Nismo edition that had a metal turbine?

Seems like none of us know!

[sav man]

Nismo/N1 are praticly the same thing, Nismo has smaller wheels and is lighter.

only a silly tuner or owner will cause it to break

ie: pushing it too far on the dyno or road

running that extra 1 or 2psi for more power

those sort of things will break it

the 32 GTR has oil problems if you intend to track it.

hehehehe just ask drunkan

ive heard of oil problems but no one had ever really elaborated

may i ask exactily what the oil problems are

i intend to track but only as a weekend warrior/club level thing

i will be getting a sump baffle kit, oil cooler and filter relocation before it hits the track

is a N1 oil pump really needed for this application considering it will be daily driven 90%

Thanks

The problem only arises when people don't put enough oil in the motor. Sounds simple, but oil surge has killed many an RB26. When you change the oil tip the whole of the 5L container into the sump, ie overfill it by about 1 litre - this will fix the problem.

As for a baffle kit - you don't really need one. I have done many track days in my car & never had a problem.

As for the oil pump - again - no you don't need one. If however you do upgrade the pump it should be matched with a restrictor kit to stop all the oil being pumped into the cam shaft covers.

You may want to consider an oil catch can, however.

thanks djr81

luckly i already have a Oil Catch Can

i think i will start a thread posing some questions about this

so keep your eyes open

and two common problems i have seen with RB26 is the AAC valve and the vicious hub (radiator fan)

might be an idea to give them a quick check
