WTB: RB26 Engine bits & pieces

[Shaun]

For an R33 RB26: Have any of you guys got new pistons or conrods or bearings (new) that youve bought and no longer need?

Also interested in some HKS camshafts that require no mods to the head.

Thanks for any reply,

Shaun.

Sorry i don't have what you want , you can get them from Nissan Hornsby , or if you want aftermarket ( forged are not much dearer ) go to rocket industries .

Another rb26 that let go the ceramic turbo wheels . How much boost were you running ?

[ferni]

Isn't it normally the exaust wheels that let go first, and should end up in your cat?

Yes you are right Andrew in part .

The exhaust wheel comes off while spinning or it snps the shaft , it hits the turbo housing and it becomes tiny pieces like sand grains , some of it can get sucked e wheel will be in the cat .

[ferni]

Or the exaust wheels heat up too much and one of the blades let go?

Whats the most common cause of the standard gtr ceramic turbos blowing?

I'd be interested to know what boost Shaun was running, and how long for.

[wrxhoon]

The heat will eventualy cause the wheel to come appart from the shaft .

I'll be intersted to know what boost he was running and for how long as well .

Andrew check your email.

It had nothing to do with boost or the turbine wheels. Heres the story: I just spent 10 grand and 8 months putting an RB26 into my R32 gtst. I had it on the road for half a day when an oil supply hose to my remote filter popped off the sandwich plate on my block and all the oil was pumped out onto the road. The plain bearings in the turbos seized very quickly, and when the turbos went from 120 000rpm to 0rpm bits of the compressor wheel broke off, went thru the inlet tract and embedded themselves in my brand new pistons. I shut the engine down quickly so i was lucky not to spin bearings or do massive damage to the crank etc. I did, however, almost cry like a baby.

This is my understanding as to what happened; if anyone has a different idea, let me know.

if you have just rebuilt the motor then i guess you know how to choose the correct bearing sizes from the numbers on the block and crank or measuring them up so therefore you need to be a bit more specific on which bearing sizes you need....i have a couple of bearings there

[ferni]

Shaun: that sucks, sorry to hear that

Jerry: ok - its my work email so dont usually check it on the weekend

[Shaun]

I understand that ill need to measure up sizes. My engine guy is doing that now so ill let you know. Thanks.

man if u had it on the road for half a day wouldnt it be covered by warranty??? or did u do the work yourself

[Shaun]
