Sure these are all bolt on and changeable for people attempting to disguise a RS4 as a 260 but they are easy to check:

  • NO front cup holders
  • NO sunroofs
  • Under body front brace
  • Fork bottom rear shocks
  • Clutch master is recessed into firewall
  • Higher redlining tacho

Thats all I can think of atm, but as stated above the only way to do it is with FAST.

Correct.

All 260RS Stags are plated as having RB25DETs. If you're ever in doubt you might be looking at/own a fake/converted 260, it should be manual, Brembos, and the recess in the firewall for the boosted clutch master are the first signs its a 260. There are other things to look for, but thats an easy start.

:thumbsup:

ok cheers, didnt check the firewall recess but all else checks out.

still looking at this stage, the complexity of the gtr setup is a bit offputting as thinking towards future maintenance etc, thinking an s2 rs would be good also neo+2wd manual, alot less headaches???

Hey mate I have the fast program and checked mine. Comes up witg a message saying "these are autech special vehicles" or something like that. If you want a VIN checked PM me and I'll check it for ya.

And yes I can confirm that they never came with RB26DETT on the plates. I'd be worried if it did. Autech recieved the bodys after plates were fitted, then installed the 26's.

And the no cup holders thing is present in all manual models from what I can remember ad they hit the gearstick.

Recess for clutch does that mean you have power booster on clutch pedal? I have an R33GTR clutch pedal on my RS4T but no room for the power booster :(

Yes get an RS 260 if they are not too dear - worth it for the better brakes, stronger rear end and engine is easy to get a reasonable power increase. Get a Nistune chip, better dumps (don't know what exhaust they have but look at that) steel wheels for turboand a good ebc and wind the boost up. Stock they are a bit of a slug.

clutch booster is gay. didn't bother when I did mine. is a pedal really that hard to push?

Yes - have a very heavy duty clutch. Not a problem on the road or track but can be a pain in the Auckland traffic as car is my daily driver. However am managaing without power assistance!!

    • There's restrictor pills in the stock boost control hoses. That's how they set the amount that was bled off and hence the "high" boost setting. The usual mod in the day was to remove it and send the "high" boost setting up to about 14 psi.
    • Thanks Duncan, that's the best info I've read. Furthermore after learning about the PCM programming side controlling the factory boost solenoid, the purpose of the solenoid is to "bleed" boost when pin 25 is earthed, thus allowing spring pressure in the wastegate actuator to overcome diaphragm boost pressure, thus closing or reducing the position of the wastegate flap creating more boost as the turbo is able to spin faster. It's pretty cool to see a designated Pill to do exactly this, would have liked to have seen it with a tiny filter over the end for those moments in vacuum.  The constant bleed pill has now been removed completely from the system and solenoid boost control has been restored once again.   Case closed 😂
    • The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.
    • Manual boost controllers (where a little of the boost was bled off) were quite common back in the day, because they were cheap and easy. Generally they had a manual adjustment screw rather than being fixed like yours. Down side is they always bleed boost, not just when you want them to so an electronic boost controller that uses a solenoid will have less lag.
    • Hello , im new here and i have A31 home build  RB25det neo stock eng / turbo  aem ems 2 blue connector  aem 3.5 map aem cas disk aem wideband connected to ecu  355 lph pump 550 nismo yellow injectors side feed aftermarket regulator  and won’t start with base aem tuner basic tune eventually flipped cas 180 degree so it triggers on correct stroke not in exhaust cycle  Now it won’t start Wideband reads 10 and 11 at lowest fuel setting  and will share calibrations soon for aem tuner i think something is wrong in aem tuner    please if you have any information, am very grateful
