My order of likely destructive events would be:

lack of oil to big end bearings due to pick-up sucking air on the track

detonation damaging pistons due to poor or over aggressive tuning

disintegration of ceramic compressor wheels due to overboosting stock terbs

impact damage when inexperienced or over confident driver fu(ks-up

Fairly obvious stuff when you think about it.

Good luck and enjoy your 'R (appropriately and in moderation) ;)

Hey guys, i have an 89 r32 gtr with a fresh rebuild...

what is the main cause of destruction of these engines as i dont want to rebuild it again any time soon.

thanks

brad

Not so much oil pump but crank collar (on R32) or R33 crank to ensure positive engaugement to oil pump is also a must IMHO

That should have been done as part of the rebuild :D

If it wasnt then i'd question the persons knowledge of an RB motor.

yes you sure do. It sits on teh end of the crank where it engages the oil pump. The early 32s used about 3mm on the crank, the 33s and later used about 1cm. I fyou look at the wear on a 32 oil pump you will see it was not enough

for a good photo compareson take a look here:

oh you will need word or some other office capable software to see it tho...... but its a direct compareson for those who are still puzzled

Edited by carl h

thought i would add a few little questions as i am in much the same situation as nugget400hp ...

Interesting about the collars! I never really knew that they were a neccecary upgrade but it makes very good sense now after reading the carl h Doc's!

thanks guys

the ceramic turbs dont sit right with me as they sound very different until warmed up to optimum temp, or well mine DO! and will be upgraded as soon as i decide on combo.... so for now its mellow crusing ...

one theory was burnt oil on turbo bearings ? Could someone please explain and why they sound so chirpy until used and temp is present in oil temp gauge or has anybody got the same noise's

its got me stuffed because the engine is a fresh build but now after study i think the turbos may not be.

basicly i dont want to pop them while there on the fresh engine.

the cars been adjusted to about 12psi but is rarley taken there and hi rev's kept to a minimum , maybe 8000 once a week for a play...

What will happen before these things die symtoms wise?.. (the ceramic turbos)

as in a good serviced lifetime?

As in bad serviced lifetime

14 Psi boost used often ?

boost used when they are first engaged and sound chirpy like i explained before, as this can take 20 minutes sometimes ideling and still needs driving time to get oil temps around where the noise changes .

And the big question what happens if one goes as in follow on engine damage ?

never heard them make a noise like you describe. doesnt sound right to me.

BTW Gav is spot on with his reasons for RB26 failure, duncans one is pretty comon too, though i think dunc has experienced first hand the ones of Gavs list too! :P

Yeh my old GTS had a t4/t3 turbo and it made a different noise when it was cold compared to when it was warmed up.

And btw look out for stcok gtr clutches, they go pretty easy.

ElBoRo

yes ... its odd, none of my other turbos have ever done it and i cant help thinking maybe something isnt flowing right until it is hot and thin causing bigger tolerence gaps in the bearings while cold ....

i will be relieved when there changed .....

    • My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though. 
    • Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno
    • Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
    • BTW I measured the jack I have, it is 70mm at the saddle but you only have about 700 until it returns to 150mm high at the cylinder so it is good but no magic bullet.
    • My experience with Rising Sun Exports Before agreeing to the sale I tried to do as much research as I could (obviously), his Facebook reviews are 98% and he goes Live at least once or twice a week. I contacted 2 people in the UK who had used him for their imports, both had positive feedback. His explanation and talk through of the import process was thorough, answering any query no matter how stupid it was. It felt as soon as the money was sent, communication dropped off. I asked for shipping updates every 2 weeks or so, not wanting to pester him, he never had any updates. I wasn't informed the car had been dropped off at the port, I only found out by his Facebook story. I asked for the photos taken at the port, knowing he would need some for insurance purposes. I received a few 5 second clips and that's it. When asked again, he said his staff had them. Weeks later I asked again, he tells me he doesn't have any, but does have 50 photos from the original advert. I never received them. I eventually got the documents sent via WhatsApp after I mentioned the port was requesting them. I purchased a CarVX report, to find out the vehicle is a Grade R with recorded accident damage, first recorded in 2017 when it was first auctioned. He never told me the grade, then again I didn't ask. His response was "Grade R means nothing, it wasn't chassis damage". Still, I would have liked to have been informed about it. Jon prides himself on being open and honest when it comes to inspecting cars, it's his main job doing so at the auctions for customers. When the vehicle arrived in the UK I noticed a few little cosmetic issues. It's a 21 year old car so it wasn't going to be mint condition. The side skirts are cracked on each corner and the sealant is failing. The front grill on the bonnet/hood isn't secured very well, mounting studs are missing. Both minor things, but again, it would have been nice to be told. During a Facebook Live walk around video of the vehicle, he mentioned it has a front Whiteline anti roll bar/sway bar. While on the inspection ramp, I noticed the stock item has been installed. When first questioned, his response was "the ARB? Switched? Since when, it never had them". Since sending video and photo evidence I've not received a response. I'm probably being over critical of the overall condition of an old car, but all I wanted was honesty (which he claims to have). I'm aware I wasn't his only customer, he's busy doing XYZ but other reviews praise him for great communication with regular updates and photos, I felt I didn't receive the same treatment.
