Best advice is if you are not entirely "Genned-up" on this, then dont do it.

Bolt on bits change many things if you want the power... like fuel pressure, air density/fuel.. to boost and detonation.. Go to a professional mate... or risk the wallet being emptied whilst learning...

Ooooother thing is if they pop the motor, they put it right again..!

Too big injector without correction will over-fuel, but get that part wrong, you risk detonation/leaning out.

Pump ok, but make sure the reg can be adjusted to suit application.

Get a PFC, It works brill, then you can start to tailor it all correctly.

It's the way I see it, personally..., you have to "Tweak" the car in a structured manner I think, it will make for a more tractable performance in the long-run.

    • Great to hear you are bringing it out of the shed again. Unless you have specific issues I'd just add the wideband, get a good tune and enjoy it. Certainly no point changing coils etc if they are working. If would add fuel pressure and e85 sensor if you are doing a general update but not if it runs OK and you are just getting it back on track. The other thing is smaller, modern twins, -5 are OK for motorsport but pretty laggy and old tech for street use (of course, if performance is the priority a modern single with twin scroll manifold etc is the go but not cheap). The final thing worth considering is switching to an ethrottle if drivability is still an issue, it should make things a lot simpler and smoother
    • Yeah pretty sure they are m4, but best to check, and perhaps use new hardware Also don't over torque them......there was that one time I lost an expensive engine after a workshop overtorqued one of those bolts and it ended up in the oil pump (no, I don't know why they removed the intake mesh either)
    • I might have to shoot them an email. Pity the exchange rate is so bad at the moment. BTW, thanks for posting that table makes interesting reading. 
    • Add these Sensors -Wideband, Oil Pressure, Fuel pressure, Intake air temp Good inspection of ignition system of coils, plugs and loom (12v feed and good ground)- a r35 kit is best bang for buck upgrade. A decent tuner should be able to see any issues with the trigger system- a link has good filtering but a good simple upgrade is the nz wiring bolt in kit. Check and replace all the fuel filters- you would be surprised at intank filter after a few years. Also good to check for any leaks on vac hoses and pipe work as has been said. No need to go overboard and spend big $$$ to enjoy the car. A quality tuner is getting harder to find as anyone with a laptop thinks they are a tuner. A link has great features to check sensor voltages and frequency inputs and easy to see live by pressing f12. The link can do a TPS & RPM fuel/ignition mapping on ITB cars then add a 4D table with MAP and ability to add a 5D to it (can help with economy at cruise with wheel speed vs TPS) Where are you located as that will help narrow down a good tuner ?
    • Reviving an old thread, I reckon my stagea is starting to slip. Car usually gets parked on a hill, narrow driveway so cant go up the driveway smoothly, anyhows, lately first gear feels "sluggish"? Not responsive. Feels like I gotta run the engine more than usual to get off the line...  Any recommendations for transmission servicing in Sydney? Or possibly just an excuse to go manual ?
