Hi guys, I have a R33 GTS-T2 and I am having trouble with it starting when the engine is hot. I recently had some work done to it tune up, boost control installed taking the boost to 15psi, after getting the car back I was told that one of the coils was on its way out and will have to be replaced soon.

I drove the car around for a month or so and yesterday after driving it all day it wouldn't start at he shops, it would start for a second and idol at about 500rpm then die, I left and came back later after it had cooled a bit and tried again this time it wouldn't start at all, the car came home on a truck and this morning I tried it when it was stone cold and it fired first time.

Battery is fine and it is turning over fine so don't think it is the starter. Am thinking maybe cam angle sensor but wanted to be sure before spending the money.

or when it's hot and it won't start, try unplugging the AFM and try and start it... could be either:

- CAS

- AFM

- Dirty Injectors (car leans out too much to start when hot)

He's got a Series II so no ignitor

Just put in the new CAS wasn't that the car wound over for ages before it started and then ran for about 30 seconds before it died and then wouldn't start again, will try AFM tomorrow, Checked the spark plugs today and all seem to be firing. Thanks for the help

93 is not S2..

Allow fuel pump to prime for 2-3 seconds on ign before you turn key to start

Ok I have checked the car over a bit more thoroughly and found that the reason the car was dying was because there was no fuel being pumped to the engine, I went through and cleaned all the connections now the car starts and idols great but if i leave it idol it will die after about 20 sec, also when the turbo spools the car backfires badly. Any I ideas?

    • My hold point for future mods is that I want a OEM detachable hard top first, but, finding one is a pain, MX5 Mania are looking for one for me, but, as hens teeth are more common, finding one in Australia is proving problematic  I can get a OEM one from overseas, hell, you can still get new ones in 'Merica, but, shipping is a absolute killer and I cannot justify the cost, or the risk of it being damaged during transport As for the aftermarket hardtops, whilst they do the job of being a hard top, and are fine for a track car, they don't seal well (read: leak like a sieve in the rain), and you need a plastic/poly rear window, plus they are a bolt in option only and not made to be easily removed I liked how the hard top on my NB could be fitted, and removed, by myself, in less than 5 minutes I know it sounds bad, but I'm waiting for someone to write off a car with one so I can swoop in on their pain, it will go to a good home though, so my guilt of this is tempered
    • I’ve got one on mine and it’s fine, 
    • No, you don't want to plug the vacuum line, as that will turn that side of the booster into an air spring and probably make it feel worse. I'm not saying that the GTR master itself doesn't need a booster. I haven't paid attention to the GTR one to know what size it is cf the non-GTR ones. But when you think about it - they have to do the same job, which is to move a little slave piston a few mm to do what it is supposed to do, and that final action is the same on all the cars. So, it is very unlikely that the GTR MC is any different than the others, because it has the same pedal stroke and the same output requirement. The booster just makes it feel easier. I'd suggest you probably have an actual hydraulic problem. It's totally common on these old shitboxes.
    • Ye, in terms of bolting up the "Conversion" from a GT to a GTT is effectively "Use GTT parts for everything" Except the subframe itself, because you won't want a HICAS/4WS subframe. Remember your ABS system will be different too, thanks to GT being the S15 3 sensor system, instead of the R34 4 sensor system for wheel speed. I do not know how people get this to work given R34 diffs do not have a provision for an ABS sensor (they are on the tone wheels of the axles). I assume***** people use S15 gear/R34NA forever when they realize this - Or they convert it to a rear diff/axles that are R33 style which I presume has the singular speed sensor on the diff itself, but then you have to wire it all in and...and... and...
