Does anyone else have the r32 workshop manual? It states compression pressure as 12kg/cm2 at 300rpm (i figure it may be a typo? 3000rpm?) for rb26dett.

it is 300 RPM you would need a bloody special starter motor and battery to turn over a motor at 3000 RPM!!!

What front end bits do you need ocean? I have a whole swag of front end bits from a R32 GTS-t that i'm willing to donate for your GTR.One problem is i'm over in W.A so there will be freight etc.PM me what you need and I'll see if I can help.

Factory WS manual specifies a minimum of 128psi, with no more than 14psi difference between cylinders.  Was the test done with the engine at normal operating temp ??

Test was done with engine cold as a rock, and with the throttles fully closed.. I can't start it (no radiator) and i forgot about the throttle..

Probably fine then.....things will definately improve with a warm engine and probably even more with a bit of a run, esp after sitting around for awhile in Japan. Closed throttle would also push readings down.

Good luck with it.

ocean, if you have GRID stamped on your ECU, then chances are it sports a nice GRID daughterboard on the inside. Basically GRID manufactures some of the best ECU reprogramming tools available in the jap market, which would mean it still has a stock ECU with remaps for the upgraded turbo's etc. Depending on what GRID daughterboard it sports, I might be able to reprogram it.

I guess i have to open the ECU to find out?

The wiring loom has also been played with right near the ECU. Is it worth re-programming this or is it better to go for a new ECU (Motec M600 or something)?

You'd have to open it. The advantage of the daughterboard arrangement is that it looks factory stock even tho it isn't :D. Whereas putting in something like a Motec ECU is obviously not (I'm thinking of EPA/police inspections).

Also if yiu get a motec you'll have to get the car dyno'd from scratch unless you can find someone with a suitable ECU map - probably difficult. But if funky can simply modify your existing maps you'll save $$$

Sounds like a good option in the short term. As long as someone can dyno tune it and it runs well i will be happy :D So if funky can modify it, how do i actually get it tuned? It still needs to be done on a dyno!!

I will open it up and take some pictures soon..

As far as $$$ is concerned you can get some cash back going to motec - can sell boost controller, ecu daughterboard, AFM's..

It should still be done on a dyno but since you already have a map it's just a case of modifying that, which is where you save. Of course there are other factors like whether the GRID ecu map can be modified in real-time, but funky would be best to comment on that.

With the Motec you can use the quick lambda function to speed things, but it saves a lot to have a base map to start with. I run an M48 pro, but not on a GTR so have been through all that.

      Leak from Tokico BM50 Brake Master Cylinder

      HFM BM57 has a "bad" knee point, IIRC. It's not the same thing as the later R chassis MC.

      Who has a Infiniti Q60, Q50 (V37)?

      The ATTESSA is functionally identical to R34; there were a bunch of JDM models that continued ATTESSA including Fuga/Q70, Skyline/Q50, Cima etc as an option. All with Auto only and I think mostly for snow regions. AFAIK there were no AWD VR30DDTT sold in Australia - it is on my to do list to check regs for racing a LHD car in Targa/ATR/AASA/CAMS events because if I can get the auto to work it would be interesting to run a 4wd car The Ecuteck TCM tuning is the same model as their ECU tuning, they already have it for R35 and Dose's favourite, BMW. You buy "points" to allow your computer to be tuned, buy either a bluetooth (phone app) or bluetooth+USB+Key (phone and PC) dongle, and pay for a tune that will be locked to your tuner ( ). You can also access the tuning software yourself but 1. it is mega expensive and 2. these computers have a billion parameters that intersect, so how could you ever spend enough time on it to get a decent result.

      Or, is it a case of what it is like owning an R series Skyline? NFI what the previous owner has done or fiddled with... Ha ha ha After reading through this thread, I went on a bit of a research about the Q50/Q60. Now I'm quite intrigued by them! Is the AWD in them more like a WRX where it's always AWD, or is it more like the ATTESSA in the GTRs? By the sound of this TCU tuning, this sounds like a case of someone has made some real software for it, and you just need the right piece of hardware, and then you license that specific vehicle/TCU. Or is this a case of the software will be really expensive so only a few tuners have it, and you still have to pay a license per vehicle?

      R34 25GT Engine Light 21

      By popular demand.. it was a coil. Got my hands on 1 new OEM coil, replaced with the one that made the less noise difference when I unplugged it while the car was running and started the car up. No stutter and the engine light was gone. I guess I’ll buy the other 5 they have lol

      No, code 21 is very straightforward. It can only be the things described in that diagnostic flow. In fact it has no way of knowing that the spark plug resistance is out of spec.
