Car has arrived !! == MERRY CHRISTMAS!!

[doridori32]

your compression is very low, good luck chaging the rings and bearigns!

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!!!

Low compared to what?

Anyway i'm back from holidays now, ready to work on the car again.

I'll keep you all posted

P.S. Thanks for all the replies

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 ??

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.

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 . 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 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.

Cool.

I'll talk to funky then and send him some photos..
