Hey i have tried looking everywhere could someone please help me out.
Im looking at buying complete gtir engine but am unsure of what else will be needed for the conversion.
I plan on starting with standard boost ect and going from there any help would be great ..
Thanks

worth looking at nistune for your ecu if you want to modify things later. consider a decent new clutch. maybe front mount intercooler kit. pretty sure you have to do something to the injectors too for a gtir motor to work properly in a n15 aus spec. consider a lsd for the gearbox.26mm radiator.

I have done this conversion multiple times,
I really like the Gti-r engines a lot,

Here goes the shopping list:
Gti-r engine, complete with hot and cold side,
Loom, Ecu, Boost solenoid, Injector resistor box, Accelerator cable,
Bigger fuel pump
Front mount and piping kit
(N14 ONLY-if you want to keep the stock top mount, you would need the Gti-r bonnet)

Some wiring will have to be done,
The Exhaust will have to be mated up or upgraded,
The crossmember will have to have a section cut out of it so the upper sump doesn't hit it,
Your De flywheel holes will have to be drilled out 1mm to suit the larger gti-r crank bolts,

I'd also recommend:
You use a heavy duty clutch,
Make sure your brakes are up to scratch,
You have good tyres on the car

Final words:
This will also need to be engineered if you like insurance
Don't be surprised if you start breaking things (like 3rd gear)

So if i buy complete gtir engine fmic clutch nistune injectors i should be good?? I have slotted rotors new pads exhaist is no issue as thats what i do for work so fab work is no drama :) .
Would 8k be enough to do conversion ??

Because your in QLD and it's cheap to engineer, 8k would probably do 2 whole conversions as long as you do the labour and source the parts at a good price

You can leave the nistune and injectors for another day,
You dont need them for stock boost and they are both no harder to instal/change once in the car,
The stock gti-r injectors will work in there as long as you have the gti-r injector resistor box,

Holy thread bumps batman, Mr Google has lead me here, putting a gtir motor into my N15 SSS and apparently i need to wire in some resistors to the fuel injectors, do you know what value resistors i should use and also any other tips for getting around the wiring issues with iacv and different injector plugs etc?? Thanks Rick

I have 2 pieces of advice...

#1 - Please change your username to 'Snowdogg' or 'Snowdawg' - sounds way cooler :)

#2 - Use a GTiR engine loom - make it work with the wiring you have under the dash and the front connector point drivers side engine bay.

Not sure if there's much info floating around about the injector resistor box. Could ask around some Nissan wreckers?

Replacing the injectors would be an easier option, that is if you're not running stock ECU
