Hey guys just a little delema im having with my car.. just done some mild modifications to the 33 over then last 6 months. 480 injectors gcg hi flow. finnaly got it back together bout an hour ago after doing the final oil change etc. started it up on the standard computer and supprisingly was running sweet. oil pressure fine temp at half way, bit of smoke from spilt oil but nothing to worry about. the only problem was i noticed that when touching the top covers it was almost too hot to touch also popped the radiator cap off and had a fair bit of pressure in there. yet the temp gauge was good. any ideas what could be going on. Could it be running hot because its been sitting for so long? or maybe fuel mix?

top covers too hot to touch is normal, your operating water temp is at least 85C which will burn you if you maintain contact. Top of the motor will be about the same temperature give or take.

Your cooling system also uses (slight) pressure to prevent the water in the system from boiling if it gets a touch warm, that's why they tell you never open the radiator when hot. If the pressure is too much you'll get water/gas bubbling out through your overflow bottle.

The coolant gauge on skylines is a bit of an idiot gauge sometimes it sticks on halfway unless something is significantly wrong. If you're worried about it then invest in an aftermarket water temperature gauge or use a CONSULT cable and laptop to read off your water temp. But by the sounds of things everything is normal!!

    • 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.

    • Unsolicited advice? Keep the engine as close to stock as you can. Nothing wrong with adding some boost and making a little more power, but given where you are, you really don't want to try to make it into a monster. I can't imagine the roads are up to it, and the lack of locla support when it grenades will be a ball ache. FWIW, If there is a dyno around that you can access, then brand new injectors are a good idea, which will lead you to (at least) putting a Nistune in it, which will allow you to put an R35 AFM on it, all of which will make it possible to make it much much nicer to drive and live with.
