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

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.

      M35 VQ25DET starter motor

      By iain_ST44GA · Posted

      Hi Guys, Does anyone know any aftermarket part numbers for a starter motor to suit the VQ25DET? I can find lots of alternative part number for the VQ35DE, which I assume would fit, but there is a lot of conflicting information out there. Thanks..

      R33 GTR running -9 with no tune

      By Murray_Calavera · Posted

      I don't understand how this hasn't boiled down to - Upgrade the turbo when you have everything required. ECU, injectors, fuel pump, turbo, etc. Do it all at once.  If you don't have everything required, just enjoy the car as it is and keep saving up your pennies.

      Sounds like you've got an interesting adventure ahead here with local support if you have trouble! My guess is that, unboosted, you will be OK with a small upgrade like -9. What will happen is that once the stock ECU sees more airflow than it expects it will add a heap of fuel and pull a heap of timing to be safe because it can't understand how it could get that much air without there being an issue. You will see clouds of black smoke and it won't pull hard through the midrange and top end. So, overall it will be a bit frustrating but should be OK. If you are still nervous set the base timing back 2o through the CAS, but it will be even more sluggish everywhere. As said above through...this is not my guarantee your engine won't be blown into a million pieces, leaving you looking for very hard to find parts A better idea is get a computer with logging ASAP, wire in a wide band O2 sensor and a use remote tuner. I've done multiple cars this way and while it is not as good as a specific tune on a dyno they can get it 90% right. I'd suggest if you can afford an R33 GTR these days you can afford an ECU and tune. And if you can't afford that you sure won't be able to afford the rebuild if it goes bad in the meantime,.

      Yeah it would be nice if someone took the time to put that sort of information together, but there are a lot of variations in looms. I think you are making this way hard for yourself if you just want to get it running....sourcing an SR20 with the right wiring will be a billion times easier than matching the RB loom to an S15 chassis. If you do end up going this way, you just need to trace every wire in the loom with a multimeter, 95% of them will go to a location you can confirm at the ECU.....and then post it up for the next person who needs it

      Coolant leak?

      By Duncan · Posted

      Just top it up with water, and keep a general idea of how much you added. It is normal for water to be pushed into and pulled out of the reservoir through the cap, and it should not be more than half full or it will be likely to overflow when hot. Any decent mechanic can do a pressure test of the cooling system to confirm if you have a leak. Keep in mind if it is only leaking a little and when hot it may well evaporate before you see it hit the ground
