I'm having problems with my car (misfiring), have done the plugs. But I hink it will either be the coil packs or soemthing with the air/fuel. The engine is a RB25 and is running a Haltech E6K.

I was thinking of taking it to APC because I have heard they have the good equipment for Haltech. But what sort of price would I be looking at roughly for a good tune??

Should they be able to fix my misfire??

Any other suggestions?

I got quoted to tune my 32 gtst, $400, i also back a miss firing problem, sound like a wrx, i spoke to my mechanic and he said definetly a coil pack has died,

so mines running on 5cylinders, and sluggish as all hell off the line, i can rev it too 5 drop the clutch and it almsot drouns itself

I *had* the same problem up untill yesterday, have a look for the thread i started in forced induction performance and read that for a checklist of things you can do at home rather then spending $'s at a workshop. I had a bad earth which cost me $9 to fix and a dead coil which cost me $35, try some of the things in that thread to diognose the problem, then if all else fails, go to a mechanic.

YOU MIGHT NOT HAVE TO GET IT DYNO'D TO FIND OUT THE PROBLEM!!!

i had similar dramas with my 32 and had it dynod at couple of different places and both times miss diagnosed and cost me alot of time and money.

A mate then told me of EFI diagnostic and repair centre at capalaba and he hooked it up and told me what was wrong with it in an hour or so and cost 1/10th the amount of cash the others were charging.

just cause a place has a dyno doesn't mean they have any idea

    • 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...
