Yeah I thought the tapping in my GTR were the injectors, but turns out its the cams or something.

What you can do to be sure is get a screwdriver and press it against an injector and put your ear at the other end. If the tapping coming through the screwdriver is in time with the tapping you can hear standing by the car, its the injectors. Otherwise, hold the screwdriver on all the bits and pieces until you find the tapping that matches.

If that makes sense... :(

its defnietly the injectors, i allready done that screw driver thing the first moment i started the engine.

The car has been sitting there for about a year.

I just needed to know if it was a bad for the injectors?, are they worn out?, does the tapping mean they arnt working right? etc etc

anyone know for sure?

I've found that the bigger single pintle injectors are a bit louder, but i would call it clicking rather than tapping (yes i'm a pedantic bastard).

my 550 rx injectors (both s5 in the rb20 and s6 in the 25) are considerably louder than the stockers.

After i had my engine rebuilt the only noise i could hear in the engine bay was my 550cc rx7 injectors tapping away as BHDave said.

Its nothing to worry about :)

      Original window sticker?

      By Celticsfan03 · Posted

      Hey everyone. Is there a way I can get the original window sticker (maroney label) for my 1995 R33 GTST? I doubt I’ll be able to ever get it but it’s worth a shot to ask

      It was a great, but typical track day, and some VB was ingested at the night time debrief 🤪

      And so, to round this out, I couldn't be happier to confirm @MBS206 has decided to buy the car. He drove down from sunny QLD with a trailer last week and it is off to its new home today. I'll let Matt confirm on next steps but I understand broadly that the plan is to leave it pretty much as is, and just get some quality wheel time with a nicely balanced car that is pretty much track ready. There are a few a jobs still to be done first but nothing too major and I think its a very smart buy Dinner last night at the Paragon with a round of VBs (mostly) for Neil

      Well, 50 pages and the end of a chapter for this car. We took it out for a shakedown at Wakie yesterday, and everything went well. There were a couple of niggles: - Oil cooler fitting leak - tightened, cleaned, stopped leaking - Radiator cap overflow fitting was leaking....Mark called it, the overflow fitting was threaded in and not tight....tightened, tested and held pressure - Small oil leak at the rear of the block, probably the turbo oil feed - too hot to get at it comfortably but probably just needs to be nipped up - leak at the driver's side rear brake line where it meets the hardline. Fitting wasn't loose, so Matt backed it off and back on, no further leaks - there's also a leak somewhere on the top of the fuel tank, maybe that cross over fuel line - that was has been left to fix when its on a hoist Otherwise than those niggles the car went great, turned great and stopped great so it was a very successful day out. I'm always really nervous when a car first hits the track after a long break, especially with a brand new engine as well but it was great. VID-20251011-WA0007.mp4  Big thanks to @The Bogan who dropped by and helped out, @MBS206 and my nephew Lachlan the apprentice.  Neil's wife Mel also surprised the hell out of all of us by dropping by; she's up in Tamworth these days but was travelling to Melbourne so had plausible deniability for turning up at the garage, it was great to see her but also obviously a bit sad all round.
