Hi All,

Ive had a bit of weird issue lately with my rb25 in my stagea. Ill be driving along randomly not under much load or anything and all of a sudden everything cuts out/goes real jerky like its running out of fuel or something. It tends to recover then be fine..... How ever over the past two days i actually had it completely turn off and i clutch in then clutch out and it restarts itself.

Today it cut out completely and didnt want to restart. Then it did after a minute or so.

Plugged in ecutalk and im getting MAF fault codes and CAS fault codes.

So im guessing i should replace these?

Ive seen different cas's on different rbs, what to i need to get?

Sam with afm how do i know what will work with my car?

Cheers,

Chris

I'd be checking your fuel system:

pump - is it an original? is it working OK

earth to pump

voltage at pump

FPR

fuel filter

before I started on anything else.

maybe even get a mechanic to test the fuel pressure? takes all of 5 minutes to do, easy as.

before you go into solution mode

whats changed recently?

when did it last not behave like this?

it would be odd for all of a sudden for the CAS and AFM to fail instantly at the same time

It has an after market fuel pump and it's not that old neither is fuel filter.

It's been on and off for a bit didn't change anything on the car and notice it coming on but it's just got worse overtime....

I just finished work (dj) and before I left the carpark I cleared the fault codes with my laptop. As it was showing codes 11 (can shart position sensor and code 12 (mass air flow meter) in ecu talk diagnostic. Had not one issue on the way home. Wonder if this will be the end of my hiccup?

      R34 Gtt Wheel Offset Advice

      What can't be done with a little bit of decking board or similar timber bolted to a hub flange via 2 wheel nuts is not worth talking about.

      R34 GTT idle problem

      By silviaz · Posted

      I noticed something. On the tps sensor and the sensor behind the adjustment screw is adjusted towards the far left. Are these screws supposed to be centered? (this sensor was in the same position before the tune as well)  Also attached a photo of where my car usually idles at when warm (sometimes a tiny bit above that). I think I might have screwed up the calculation and it might have better than I thought lol at 750rpm still not 650rpm though.

      So for both general interest of engine health, and to rule out any coolant/oil issues, I organised an oil analysis done on the 125,000klm oil Results below, all good, just a bit of fuel dilution which I'm not too worried about

      This is actually a really good way of measuring what wheels fit. If only there was a similar measurement between hub face and suspension :p That said, it's probably pretty simple to actually measure it all with the wheel off the car for the rear. The front is a bit more complex but..

      Being the top Google search result for R34 wheel-related inquiries, lemme throw down my experience. I calculated that 100mm from hub face to wheel face is about the perfect fitment for my ENR34 sedan.  I've been running 18x8.5s, ET35, with a 1" spacer. So, 8.5in to mm = 216mm. 216/2 = 108mm. 108-35 = 73mm. 73+ 25 (1" to mm) = 98mm.  If you wanna get close to this on dif widths, here are the offsets you'll want: 9" - ET around 15mm 9.5" - ET around 20mm 10" - you're crazy, but ET around 30mm All these should fit perfectly on a non-widebody, non-GTR Skyline. Note that it's probably the absolute max, and you're probably better off running a couple degrees of camber in this config, but it looks great, super flush.
