Gday All,

I have an RB20det cefiro with R32 motor+ecu, its got:

GT2871r

gtr injectors (individual resistors wire into loom)(had these cleaned and checked before fitting them.

Z32 AFM+pod

fmic

3 in exhaust

remapped ecu

new yellow jackets

I built this a while ago and it ran mint but now its got a miss, sounds like dropping 1 cyl intermittently.

It first started playing up during a local skid day, miss would drop in and out all over the track.

Ive looked for boost leaks, loose connections, found none.

Ive chucked another ignitor on it the other day and a new set of plugs(bcpr7es gapped .7) this morning with no success.

First test drive 3/4 throttle went mint, second drive flat out started missing maybe 5000 in 2nd gear, continued other gears and high rpms.

HELP- What the heck is going on? Its ticking me off and Im just about ready to take it to the mechanic.......

all help appreciated!

Thanks very much for the reply!

One last dumb question, how can I test them or get them tested?

I reckon Ive had them less than a year, car has prob done approx 500km in that time so hopefully I can get money back/get them replaced.

    • Have a vb in honour of the car comming back
    • 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.
