I recently bought an R33 GTS 1993 model Skyline, On cold starts the revs rise up and down between 1000 and 1500 rpm for the first couple of minutes untill it is at operating temperature, it is also seriously lacking performance, i'm not sure whether it has been serviced properly as i am the first owner in australia.

anyone have any ideas with the cold start problem and maybe a checklist to get the engine running properly?

thanks

It is meant to idle at approx 1500rpm for about 5 min or so until the engine warms up. It should not fluctuate however.

I'd start by giving it a decent service. At minimum change engine oil, oil filter and air filter (or clean air filter).

Its amazing how much difference an oil change can make.

if you are the first Australian owner then there is a host of things that you can do to make it go quicker and more econmical extractors - mandrel bent - big flow cat- bigger t/body port and polish match inlets a rising fuel pressure regulator and some sort of engine management and maybe if you are really keen find yourself some cam gears and advance the timing a little this should see you add extra h.p and more importantly more torque in the low to mid range

did u import an R33? congrats.

by lack in performance what are you comparing it to? a couple people here have CA18 and RB20E R33 GTS... Check if you have one of them.

Pretty much what Greg said, and I'd do the fuel filter, radiator flush, spark plugs, gearbox oil, differential oil, brake bleed, new brake pads probably.

These are relatively old cars, so they need a lil more attention - and the peace of mind knowing that every fluid/filter is changed is good.

A dyno run would show if the engine is running ok too.

    • Is the panel filter one that is oiled? Have you ever cleaned or touched the AFM?
    • So.... the K&N air box thingo was too big, ended up gifting it to a mate, well, by gifting it he actually supplied food and beer at the pub,  which was nice, as it will not sit on a shelf in the garage for the next 10 years I did trim up some of the existing stuff to neaten it all up and gave it some wrinkle paint, unfortunately it currently has a used and abused mish mash of different types of hose clamps, 4 big fat T bolt type (shit), and a few normal clamps of vairing sizes and brands, but..... only until the 6 constant tension black worm clamps that I ordered from EFI solutions turn up next week Currently the current hose clamps are triggering me hard, LOL Is this the final version, probably not, I really want just 2 silicone pieces, a straight bit of silicone from the filter to the MAF is easy and will happen as soon as I head into Just Jap tomorrow, the problematic part is a 30° silicone bend from the MAF to the TB that I can connect the engine breather from the head, I found that there are bulk head fittings for boat bilge pumps that should work, but until I can get a 30° silicone bend the alloy pipe, and the 11ty thousand hose clamps, are there for the foreseeable future 4 hose clamps are golden, 6 are grudgingly acceptable, the 8 currently holding it all together is just taking the piss    I've also ordered 60 more retaining wall blocks for the front yard, I mis-gonculated the height that was required to get above the base of the Photinia's (red robin's) that are the hedge behind the front fence, currently it is 2 blocks high, and about 1/2 a block short, so going 3 blocks high will be above the base of the red robin's, and allow some room for mulch
    • It is the stock air box with the panel filter. Everything else is stock except the exhaust at this point, as I also went back to the cleaned 270cc injectors. I will check the RPM when the IACV is unplugged and report back.
    • As MBS suggested if this is happening when the engine is cold you're going to want to remove the intake air regulator and verify resistance + that the shutter is physically opening and closing. At -20C should be fully open, 20C half open, over 60C fully closed. At 20C should be 70-80 ohms. For AAC valve testing using a Consult cable see if you can raise and lower the idle by commanding more or less AAC duty cycle. Hopefully it's pretty linear as well, shouldn't be like 30% AAC valve is barely idling and 40% is 1500 rpm.
