Change in topic but its a simple question ..

Wit my current mods and soon to be verso tune, should i be looking at upgrading my injectors? I understand ill need a larger fuel pump for the tune but was wondering when should i be upgrading injectors?

What are some good ones?

i'm a big fan of any mod that improves efficency, equal length headers, heat retention, porting and improving air velocities are what make power, you might not have fancy chequebook racer parts fitted, but the results at the end are cheap if you spend the money wisely.
you upgrade your injectors when you run out of injector duty, depending on your tune and what compensations your ECU is tuned for- you could probably draw a line in the sand at 95% IDC before needing larger injectors.

I was told with my mods, there wont be any need for em, but have heard from people with similar mods to mine with em and they like em.

Just gonna get more opinions ..

Get the turbo,front mount,headers and then get your verso tune It will save you a lot of money in the long run...

I have a set of xforce headers If you want them..

headers dont work, thats why no-one uses them, or even makes them for that matter.

You try searching for extractors for a wrx, I think X- spec or something are the only manufacturer that makes them, no-one in Japan or america or Europe does.

true ..
Ive only found x-force and dodgy looking ebay ones. none from big brand names.

What are some other mods (excluding bigger turbo and front mount) you guys suggest me to get before my tune? Maybe a stupid question but who cares .. Do lightened crank pulleys need to be tuned for?

ROFL there are tonnes of different brands of headers for WRX

Xforce, Perrin, Tomei, BPM, GT SPEC, AVO etc etc

[Evidencee]

what ones u recommend?

[POLARBEAR666]

I agree with the guys above that at stockish power levels the stock headers should be fine. I think that equal length headers or almost equal length are the way to go. Personally I like the GT SPEC headers as they have a nice 4 into 1 collector and not so many bends as the true equal length Xforce. Get the GT SPEC 4 into 1's ceramic coated version and that should give you a power increase, reduce the db of your car and equalize the exhaust gas temps coming out of each cylinder so one does not run super hot.

I find the lack of a boxer beat means cops will let me off much easier.... hence no Yellow despite being pulled over and ticketed about 3 times. and pulled over 5 times total.

hmm, i think im might just save my money for something else, dont think they will do much for me at this stage. Just one quick question, do MY03 WRX's have a cat in the up-pipe?
