Hi everybody.

I've just recently purchased my R31 GTS-R

that has an RB25DET conversion.

Last night with Dr_drift and Meggala we establised it has a series 2 RB25.

ALSO... now this is the bonus part.

The ECU was just sitting on the floor behind the carpet and a few screws were missing.

So we HAD to have a look and one opened up we saw that the ECU had a nice daughter board with a chip... :eek:

A fully programmable chip that is.

Right down the the valve timing.

How cool is that. :Party:

No $1,500+ APEXI Power FC for me to tune the ECU and go fast :burnout:

No... this isn't the R32 chipped...

i was gonna let dr_drift play with that on mine for some ground work but there's more better things now.

It's a 33 ECU with a daughter board and on that board are several chips.

This car was a race/drfit car in Japan and has many mods.

As for markings on the chip or nothing... there are none. It's a generic sort of chip with the maps bunrt on it.

It looks like someone has done it in their bedroom sorta of thing... not something brought off a shelf that's for sure.

Maybe that's why it goes so hard

:D

series 2 RB25DET

Massive STOCK frount mount

I think it has a T04E.. them came with them stock so i'm assuming it's what on there. Hits boost about 4,000rpm.

turbo extractors... STOCK

stainless steel exhaust manifold... again Stock!

It's got coils overs all round. Cusco is what's on there (i've got spare 500 pound springs as opposed to the 250/200 that are in there now)

5 Stud converstion -- > R32 GTR brakes

shortend shifter

R32 Forged GTR Rims

Monster heavy clutch.

260 km/h IMPUL dash

of course the ECU is modded

There are extractors coming off the block going into the turbo.

And then off the ass end of the turbo.. the exhaust manifold is stainless steel.

so that is different is it not ?

or wan't i clear ??

And the stock front mount for a GTS-R is huge. TRUST ME. i know lot's about the R31 imports.

If you see the car i can explain it.

The GTS-R's were brought out (only 800) for the group A racing.

That's why it has lot's of good stock parts.

off the block to the turbo is called the exhaust manifold and from the back of the turbo is called the dump pipe!

:D

Yep!

I'll be there for sure.

it has no extra boost so i guess it's running around the 9psi mark with the big cooler and exhaust...

i'm being a bit conservative but i think i should get at least 180.

Dr_drift is more towards the 200+ though.

we shall see on the day though :P

Might even do some tuning now the ECU has been found to be chipped

R31Nizmoid - Cool, if Dr-Drift can work out how to re-map the R33 ones it'd be great. But I think the write once 84 pin chips are about $70, and the re-writables are about $250 or so !!!

Unless your ECU daughterboard got rid of the 84 pin chip all together and uses a cheaper chip - now that would be cool..

      After market rear camber arm adjustment

      By Duncan · Posted

      Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber

      I know I have to get a wheel alignment but until then I just need to bring the rear tyres in a bit they're wearing to the belt on the inside and brand new on the outside edge. I did shorten the arms a bit but got it wrong now after a few klms the Slip and VDC lights come on. I'd just like to get it to a point where I can drive for another week or two before getting an alignment. I've had to pay a lot of other stuff recently so doing it myself is my only option

      You just need a wheel alignment after, so just set them to the same as current and drive to the shop. As there are 2 upper links it may also be worth adding adjustable upper front links at the same time; these reduce bump steer when you move the camber (note that setting those correctly takes a lot longer as you have to recheck the camber at each length of the toe arm, through a range of movement, so you could just ignore that unless the handling becomes unpredictable)

      I got adjustable after market rear camber arm to replace the stock one's because got sick of having to buy new rear tyres every few months. Can anyone please let me know what the best adjustment length would be. I don't have the old ones anymore to get measurements. I'm guessing the stock measurement minus a few mm would do it. Please any help on replacing them would be fantastic I've watched the YouTube clips but no-one talks about how long to set the camber arm to.

      Heh. I copied the link to the video direct, instead of the thread I mentioned. But the video is the main value content anyway. Otherwise, yes, in Europe, surely you'd be expected to buy local. Being whichever flavour of Michelin, Continental or Pirelli suits your usage model.
