Gt4 Injectors In To Celica Gt

[Rowbotanator]

Can the gt4 injectors, fuel pump and sender fit a gen 6 celica gt. i want more out of my car, im getting air intake uprated coils, uprated exhaust system and hks harness earth kit plus once all done a re-map to bring it all together. so for the fuel side i need something better anyone any idea's I NEED MORE POWER!!!!!!!!

i doubt youd need them tbh, you need more air in before needing more fuel and i doubt those mods would warrent bigger injectors etc. what sort of re-map are you going for???

[dawesy]

nope waste of time IMHO. you have a long way to go before needing bigger injectors. and you will need a mappable ecu too

Agree with whats been said above..... The Injectors in a ST202 are 315cc (ST182 = 295cc and ST162 = 250cc). The standard injectors are good for about 210-220bhp at about 90% duty cycle, and your not going to be anywhere neer that with what your planning above. The St205 injectors are 550cc which are good for 370bhp roughly, far, far to much for what you need. As for will they fit, yes they would, but you'd have a to low duty cycle IMO.

Also the Standard ECU cannot be re-mapped, you'd need some form of piggyback.

Hope this helps

just on another note they don't physically fit either, ST185 440cc ones are a side feed, and the GT ones are back fed- meaning the fuel rails are completely different.

Thanks for the replys this is helpful also why is the original ecu not able to be re-mapped? as far as my knowledge gets i thought all ecu's were able to be re-mapped? i.e the minor tweeks? plz reply?

it's just because of the old style of chips that were used, ROM chips that once programmed are unable to be edited, you can however get the chip replaced, hence getting your car chipped, it just depends on your budget

If your wanting to up your power go for the basics, filter, exhaust, remap on an N/a if your after a lot more power cheaper buying a turbo car or buy a turbo engine ( around £500 these days).
