i am quiet happy to have to replace the inturnals if i have to and to spend 10-15k on it. but

i cannot afford to drive the car 100km+ to have it checked out then 100km+ back home....that would mean taking time off work.

mate on the one hand you say you can spend 10-15K on a rebuild, yet you cant 'afford' to drive it 100kms? or tow it? weird.

read the bold!

thanks for that advice. i read what he wrote. perhaps the 60 seconds or so requried to call a tow truck could be squeezed into his high powered schedule?

anyway, none of it makes sense to me. you've got $15K for a rebuil but wont spend $300 to get it to the workshop to find out if it's ok or not? or even better find a closer shop (if there is one).

not bottom end...still a noise but made somewhere else.

a bottom end is consistant, this seems not too be consistant, as when i was driving i got 60-70kms without any noise, then all of a sudden it started, pulled over and my speed dropped then it went normal for a few seconds. decided to pull over so i pulled called my friend and was thinking to myself"oh no" left it for a bit until my mate got there started it up and it had stopped, then went got a drink came back started it and the noise just started again. went up the road to friends house. check a few things. start ity again no noise...leave it for a while longer then decide to head home. started the car and it was there again, driving back it cut in and out 2 or three times(cutting back to normal)

i have a good idea what it is...not goin to cost anywhere near 10k

My oldschool R31 with a redtop rb20 in it had a similar problem only slightly more advanced.

If you held the revs at about 2.5k you would get a metallic banging (not quite as deep as knocking noise) anyway it was consistant and definately bearings. When the motor was reved out (shit motor didnt care if it exploded) sometimes it would make the noise others it wouldnt. Car was also really down on power sometimes others fine.

But the noise is exactly the same as you describe it. SERIOUSLY STOP f**kING DRIVING IT!

Change your oil filter and pour the oil out on some paper in the sun and I bet you will see silver sparkles from the shagged bearings in it. If you insist on driving it put some thicker oil in it.

i found out exactly what it is now

to day i took the coil cover off(when the car was runn ing normally again) what it was running and i removed a lead that connected to the 1st coil pack and walla!! started to run like shit. huff and puffing, vibrating! sitting in the car it almost sounds like a knock but out side of the car it sounds like a WRX...so i having problems with coil pack or the wirinig somewhere.

very similar to the discription on a bottom end going! trick me and a few otha people.

from the start the noise i discribe was a more of a muffled knocking...like wood on metal, not really metallic.

Of course if you remove the electricity supply from the coil pack its not going to run properly, it means one cylinder isnt firing.

If you think thats it, when the car is running like crap disconnect coil packs one at a time. If when you disconnect each one the car runs worse, its nothing to do with ignition. If you disconnect one and theres no change in the car, then thats your problem.

      R32GTR R200 reverting from Nismo centre to stock

      By djr81 · Posted

      It is possibly 55 degrees for the Nismo version. I had a look through the manual and the stocker has a breakaway torque of 2.5 to 3.5kgm. Supposedly the Nismo LSD goes down to 5kgm when worn in but it is pretty grabby even with very little throttle. Worse when cold. So I guess you have three things. 1. Shims. 2 Friction plates 3. Cams Would think shims would be the easiest but Ive no clue how many tenths of a mm shim thickness change equals how many kgm torque. Also not sure if the Nismo friction plates are similar/different to stock or if they are the most of the source of the diff being angry. Think I can write off the Nismo rebuild kit for the standard diff as not being what I want.

      Yeah, it was a bit of confusion with me, I rang and asked if they had a boot for a soft top, and then the paint shop when they rang and were asked if it had a hard top on it, which it does, just not a PRHT....LOL Meh, whilst frustrating for all concerned it isn't a war stopper and should be a thing of the past in a week or two In other N/A related news, car is booked in at the end of the month for the cams, springs, retainers, harmonic balancer and retune  I might even pull the lazy arse card and get them to do a full service on it whilst it is there

      Factory LSD is supposedly a 2 way with a very conservative cam. If you've already tried adding friction modifier to the diff oil and it still locks up too much for your liking you might want to adjust the ramp rate on the cam to be more like OEM instead of reducing initial torque even further. People claim the 8 kgf-m disc kit for the OEM LSD is still very streetable but I've never been able to compare everything side by side on my own.

      Oh man, at least it sounds they've accepted they stuffed up and not put it back on you...could see some confusion if they asked if it had a hardtop or not, and you've answered truthfully but maybe not answering their real question which is what roof did it have from the factory! Glad your keeping it N/A 2.5

      Nah, I much prefer colour matched Talking about colour matching stuff, the new/used boot lid turned up, all painted up perfectly......aaaannnndddd, it's for a power retractable hard top, not a soft top.....LOL They are now sending a boot to fit a soft top.....,  whilst frustrating, life is like that sometimes, sometimes you just need to dodge, duck, dip, dive and, ummm, dodge.
