Been looking for red 740cc injectors for my95 wrx import but can’t find any,I’ve been offered yellow decapped injectors which are apparently 800cc, would it be better buying original red 740cc or decapped 800cc yellow injectors, Car was on a dyno last week and only produced 286bhp with mods,mapper said get red 740’s as I’m looking to gain 340ish, so going to change Injectors and map sensor. Never come a cross decap injectors before.

any help appreciated.

Yellow 440cc injectors will get close to 340.

edit:

550cc are good for nearly 400BHP why would you need bigger?

Hi mate what mods on your car to get 352bhp? If I could get that I’ll be well happy,

nice mate 👍

Thanks to all the replies guys appreciate your advice, spoke to Mapoer yday he said he only advised bigger injectors just in case I wanted more power later on,told him 340 is all I need as don’t want to put too much pressure on standard gearbox,so he now said get yellow 440’s that will see me 320-330 at a push,still low to be honest, I’m stuck with one mapper as I have an Alcatek ecu and this this mapper is the only one who can access it.

If I were to get yellow 440’s,3 bar map sensor and fpr should I be seeing more than 320bhp,
