GTR injectors on GTS25T?

[turbomad]

Will GTR injectors work on a R33 GTSt, are they physically capable of more flow (cc) and have they got the same impedence so that the stock R33 ECU can run them?

i dont think it would even work 2 be honest.

gtr injectors are top feed, low impendence

r33 gts are side feed high impendence.

since its low impendence, you would require a new ecu to run the low impenence ecu.

i havge been looking closely at the injector setup. Have you considered trying a fuel rail from an RB20 (top feed) with injectors of similar resistance as the RB25. Like Mazda 13B Turbo injectors come in 2 resistances and flow around 550cc.

A remapped ecu, or aftermarket ecu will be needed to handle change in injector flow.

[Joe]

ive heard a remap ecu wont work due to the driver of the ecu

the ecu was designed to only run high impendence injectors

but hey i could be totally wrong & u can remap the ecu 2 run low impendence injectors.

Well I was trying to avoid using diff/impedence injectors cos then I'll be up for a PowerFC as well, you know you've gotta draw the line somewhere, just wondered if there was anything off the shelf that the standard ECU could handle.

Can anyone confirm that the Mazda Rotary injectors have the same impedence as the RB25DET?

GTR into GTs-t don't work at all.

depending on how hard your modded up, a good mild swap is 440cc's off a 200sx or even better 480cc off a JDM Silvia or I think GTi-R.

I'm pretty sure their a straight fit.

GTR injectors are top feed low impendence

RX7 series 5 are top feed high impendence

R33 gtst = Side feed high impendence

you can change the fueling systems.
