Can i use r33 made injectors on a R32 ?

or are they all the same ?

coz i rang bosch and they said they didnt have r32 injectors.

[adam-__-]

R33's (if they have the Rb25 engine) injectors are side feed and won't fit into the R32 (if it's got the Rb20 engine). Just get your hands on some second hand GTR injectors. They go for about $300 on here.

R32 what? RB20DE, RB20DET, RB25DE, RB26DETT ?

they are all different is size, but all top feed, so no R33 will not fit unless its an RB26DETT engine you have.

you can not change size unless you reprogram the ecu either, so you must get the correct ones for the vehicle you have.

my advise is get a good s/hand set and get them ultrasonically cleaned if they need replacing for whatever reason.

hmmm thanks guys i mite go for the gtr ones ?

how much power can they handle ?

thanks

What motor do you have?

If you don't have the correct size injectors then you need a Power FC or the like - otherwise the engine will run very rich, it will look like you have a blown turbo

i have a rb20.

i have an safc too if that helps ?

my turbo lags atm and doesnt go past 5-6 psi ?

the place i took it too said it was running rich or lean forgot which one was aegis ago. lol

GTR injectors can handle high 200rwkw and maybe even 300rwkw.

You would need a resistor pack of some sort and a retune of the standard/aftermarket ecu to control the new injectors. You won't be able to do it on the safc as far as I know.

How much power are you making at the moment? And how much are you planning on making? You can keep the standard injector and make 200+rwkw with a good tune. Just make sure they're in good condition and are clean.

[Nefret]

chasing around 250ish

got around 180ish

but i need to get a tune really badly atm

so i was thinking get injectors fuel pump and afm and get it tuned ?

[adam-__-]

Yeah, you can do that. Save costs on tuning time as well.

For 250rwkw, the GTR injectors should be fine and get a Z32 AFM to go with it. Don't forget about the resistor pack if you've got a stock ecu.

[Nefret]

how much is a resistor pack ?

[adam-__-]

You can buy a genuine one for ~$120 or make one up yourself. If you want one made up, just go to jaycar or dick smith and buy some resistors and make them some how I can't remember. Try a search on the forums and you'll find all the information you're after. I think it was Roy who also made a tutorial on how to connect up the resistor pack.

Thanks alot.

alot of help !!

what does a resistor pack do

[adam-__-]

The standard rb20 injectors are high impedance and the gtr's injectors are low impedance. What the resistor packs do is it increases the resistance for the standard rb20 ecu to be able to control the gtr injectors. It's something along the lines of that, not 100% sure though. You just need it if you've got the standard rb20 ecu and plan on running any low impendance injectors.
