GU injector pump question

Post by REV_310 »

quick question...

thinking of buying a gu 4.2 injector pump came off a turbo girl. he says its got some electrics on it i'm guessing that the tps. anyway this should go into my series 1 gq 4.2 with aftermarket turbo so i can run the boost compensator

td42 t are simple no computer the td42 ti the intercooled ones have a simple computer that runs the fuel pump advance. the motor will run but u will hear it diesel knock a bit and lack a bit of power.

if its off a gu td42ti it also means it will have the nads (anti theft set up ) so unless you get the computer as well it wont run, prob easier getting a boost comp fitted to your own pump

Anyone wanna point me in the right direction with fitting a boost comp to my injector pump. Like sourcing one. Off shelf or off gu pump. If off gu pump wouldn't it be easier to just swap pump

the factory turbo(non intercooled) td42 pumps only have one wire going to the pump for the fuel cutoff solenoid and fit onto a gq easily but you will need to fit the accelerator cable bracket from the gq and change the plug on the fuel solenoid which only requires undoing the 8mm nut on top of it and the fuel supply pipe is larger on a gq but fits straight on the gu pump i have 2 gu pumps in the shed i was thinking of offloading as i dont need them but dont know what they would be worth

If they are the earlier 10mm headed pump not much but if they are the 11mm late model ones ive seen em go for $1500 second hand
