hi i have a 1994 v2 wrx not sti and am away to turn boost up what suporting mods should i have first i.e injector ect. was looking at v1 k reg type ra sti injectors would these be bigger than my standard injectors or is there any other v1/2 injectors that are bigger or better that would be a straight swap. only thinking on rasing the boost a bit to about 1.2 maby 1.3 max as not sure what the turbo or internals can take on standard wrx and want car to be relyable aswell as fast nor do i want gearbox packing in for that matter as have just had to replace recently already as a seal was gone. what other supporting mods should i have! just fitted a set of hks spark plugs so spark shouldnt be a problem but any more advice anyone has would be much appreciated also whats the best way of getting more power as cant remap and have an auto box so new ecu not an option. also what turbo will this car be running it a v2 1994 wrx import think its a td04 but not sure

Your car should have a TD05 turbo and am pretty sure grey 380cc injectors,have a look to see what colour they are.
Next size up are yellow 440's
I'm guessing you intend turning the boost up using a MBC?
Bad move!!!
Also slapping In bigger injectors is a bad move!
If you want to kill your engine fast then do it.
Have a look at ESL (enduring solutions) this will make your ECU mappable,then it will be safe to upgrade injectors ect
Bigger injectors need rescaling and more boost requires a change in timing and fueling.

hi got told you cant remap an automatic ecu as it has something to do with the gearbox is this true? it says they can map AT foresters but not sure about imprezas also where would i have to go to get it maped?

Sorry I know nothing about auto box,someone might come along with more info.
I would give Andy Stevens at enduring solutions a ring or message him(he's a member on here) . He will let you know if ESL works with auto box.
