hey guys this one is for all the peps that know about the RB26DETT, i just bought a R34 GTR a few weeks ago and last night noticed a noise that started when i was in lower gears under power, i was able to record it thismorning and have uploaded it. Some friends think it is lifters. The oil needs to be changed so i have bought some lifter addative and injector addative also, if anyone can ID the cause of this would help alot or even give me a place to start.

The car drives fine also, hits all gear shifts comes on boost, it is allso factor stock besides suspension and exhaust.

Cheers

Yeh i did, had nissan in tasie go over the car, they pulled off the turbos did a compression test, all came up good, the onlythings they found was diff pinion seal needed to be replaced and also weaping sump, oil pressure is fine and oil is full, it is rather black tho so this is y im gettihng it changed tomorrow and adding the lifter addative.

I don't think your lifter additive will do anything. Reason being, and more knowledgeable people will correct me if I'm wrong, but lifter treatment is traditionally for motors with hydraulic lifters that suffer build up of contaminants. The RB26 having solid lifters cannot suffer the same problem. The lifters can need re-shimming if out of spec, the hydraulic ones are self clearenced.

Does it rise and lower with Revs, or road speed?

Could be a number of bad things unfortunately.... hope its something more simple

if its done im going to have to sell it cheap and just by something for 10k and cut my losses i think, its my daily to and from work w/o a car i cant get to work.

That sux man, but now you know why they say, if you buy a gtr you better make sure you have enough money to buy another one (implying a engine rebuild)

i would have thought if it was a big end or blown engine that the noise would have been there the whole time and not just when i accelerate in 1st and 2nd, and over 3k rpm in 3rd the noise is gone alltogeather.

yeh 3 months and i would have the cash to rebuild it but getting to work is a real pig without a car.

I remember writing this....

On your number one point, no its not hard. Just expect to reach deep into your pockets. If you can do work yourself, and do some research into it, Rather than just taking whatever is in a kit, then it works out much cheaper.

Remember, gtrs have their failings too. You might go get one, and spin a bearing in your first week. Hello 8k basic rebuild.

Cost for cost, once and engine rebuild is taken into account the V will not disgrace itself against a gtr in a straight line. It doesn't have the benefit of awd, but it is also more comfortable and easier to drive IMO. And you'll never end up with oil in the rockers in a vq!

Terrible luck mate....

Don't sell it though, to move a car like that in the time frame you need to get another car, you'll be looking at getting 20-30k if your lucky I would think..

Maybe diagnosis it, if bad, buy a crapper then save for the rebuild...

Fingers crossed mate...

Hey mate sorry to hear about the car. This is my biggest fear, im currently looking for a 34 gtr and would be in the same boat as you if I bought one and this happened. I keep reading peoples posts about this happening so often with their GTRs and it kinda got me thinking of just buying a 32 gtr, that way i would have enough money for a rebuild.

If you dont mind me asking where did you get the car from and how much did you pay?? You can PM me if you dont want to post it here. Cheers.

Hopefully you get some good news from the mechanic but with my limited knowledge this sounds pretty serious.

    • I hadn't thought about the variable power steering assist. Presumably, it will always be the same level of assist as you get in an S14. The R32/3/4 are either helliishly heavy (at low speeds) if the solenoid is not powered at all, or hellishly too light (at high speed) if it is powered all the time. I presume that it is PWM controlled on those cars. I hadn't thought about the S cars not having variable assist. ugh. What crappy plebby cars they must be!  
    • Hmm yeah that is a good point. It looks like it'll just bolt in with no real issue besides maybe the bushings being different. My other concern was that 2 pin plug that I assume is used in some way to control the rack solenoid depending on the speed signal from the ecu. The DMAX rack doesn't even have that plug though so, don't think it'll matter. Might just order the rack and see how it goes. Will update this when I figure something out
    • I'd say it's a fair bet that the feed and return fluid lines will be in different enough spots that you would need to come up with a way to cut the originals short and adapt with new hard line adaption or braided teflon hoses or somesuch. But really, you have the car, you have the photos of the DMAX rack - you should be able to go out there and see for yourself whether they're in the same or different spots.
    • I've been doing some looking around and honestly was just considering throwing a new rack at it. I saw that the dmax silvia rack bolts up into the 33 with the silvia bushings but not sure if the high pressure lines will sit in the correct spot. I believe other version of the 33 rack are the same/similar to the racks that can be opened up without as much fuss so I assume the dmax rack would fit but any ideas?
    • I've never played with one, but I would expect that you are correct. That slot looks like it is intended to be used to unscrew the end, and the flats on the body would be better than grabbing it around the round bit with a pipe wrench. So, yeah, probably unscrews. You'll probably have to make a tool to drive in that slot.
