I get a lot of different opinions on the specs of 32 gtst injectors,

most of the confusion is from people trying too sell injectors for it but they arent legit and the size is wrong. (ebay etc...)

I know they are top feed

I do know they are high resistance, but how many ohms?

How long are they? Full? Half? 1/3?

What type of plug is it?

They are 11mm right?

Pressure 42 psi right?

Flow 270cc right?

Whats that other pressure rating about?(sometimes theres another one in the specs)

ANY other or more specific info would be great.

Any suggestions for NEW not second hand injectors would be appreciated.

Resistance.. I used 10ohm resistors when wiring in the GTR injectors, I think total the stock injectors are 12-14ohms

Length.. not sure, would say full (longer than my new injectors which are apparently 3/4 length)

Plug.. GTR is Bosh EV1 style and stock plugs fit GTR injectors if the locating tab is filed off.

I think they are actually 10.5mm not 11mm

Fuel system is a 3-bar system so with no vacuum signal you should be seeing 43-44psi

And yes, 270cc

Changing to a GTR style setup will open your options right up and it's just a small wiring change. I spent big dollars on drop in replacements but the latest setup I just went with second GTR injectors, made my own resistor box and made a whole new injector harness with brand new bosch plugs. Bang for buck :thumbsup:

I got my drop in replacements from Powerflow Injection I think they're called, supplied plugs too but they were second hand chopped off some loom they had laying around..

      Sorry, are coilovers ACTUALLY ILLEGAL in NSW? They aren't in Vic, as long as they retain 70% of stock travel and the car is above 100mm off the ground. Does NSW actually have a law making coilovers actually illegal? RWC/Blue Slip/Engineering people not knowing the actual f**king laws boils my blood. Demand them to point to the documentation that states a coilover is illegal. (it may exist in NSW )

      But seriously, can we ask for the results of the "tip a bottle of metho into a nearly empty tank" experiment?

      Hang on. Let me get this straight. The desire is to have coilovers, BC in particular, to be MORE comfortable on Sydney roads than stock suspension? Well, that's obviously not right. BCs have crude damping design at the very best, and typically hard spring rates. BC stands for Billy Cart. And then, the desire is to put in some shitty old worn out stockers, to get it blue slipped and then put the BCs back in? And then.....what? Not worry about getting pulled up by the Plod? Because you seem to have raised a worry about paying for engineering (which actually does solve all your legality problems) and still getting pulled up.... but the only problem there is that if/when that happens you have to show your paperwork at the inspection station. Whereas, if you just swap in borrowed shitty old stockers to get it slipped now, and then you get defected in the future, you have to go find more shitty old stockers then too. You course of action looks like this set of options: Buy brand new stock type dampers, and springs. probably cost a bit more than $1k all up, but will last for the remaining life of the car. Put them in, pass inspection, drive on them forever more. Hell, they could even be really nice Bilsteins and Kings or other lower&stiffer springs if you wanted. Get the car engineered as is. ~$1k. Buy new Shockworks coilvers (or MCA) and also pay for engineering. You're spending a lot more here. But these will be the best things that you could drive around on.

      Might be worthwhile hitting up Facebook's groups, I know most of them contain terrible people and scammers - however you might be able to find someone that's in Sydney with factory suspension you could purchase and/or hire. Just do not send any form of money anywhere, in person cash only.
