I am booked in with Andy F in December for the usual () and are currently in the process of sourcing and fitting parts to my MY05 WRX, hoping for at least 300/300 but also understand the "Pub Speak" element to this and want quick spool up with a wide torque band (Why I chose the turbo) with reliability.

I am pretty sure the limiting factor from the mods I will have done by then will be the fuel pump / Injectors and am trying to decide whether or not to do something about it before mapping time. So as Andy is a busy man and can do without me bending his ear for hours I thought I would ask you folks first.

Here is a list of what I have planned prior to visit...

Green High Performance Panel Filter - Fitted
STi v8 Intercooler, Intake & Undertray - Fitted
Blitz® NüR Spec R 3" Cat-back Exhaust - FITTED
Prodrive Sports Cat (Off a WR1) - To Fit
WR1 Up Pipe - To Fit
AFP4H Turbo (TD04 Hybrid) - To Fit (Good for 320 right?)
EGT Sensor Resistor Mod - To Fit

So, looking at that list should a fuel pump and / or injectors be considered for optimum use of the mods and reliability bearing in mind I don't have a bottomless pit of money ()?


Thanks for any advice offered...Dan

i would seriously consider changing injectors standard on a wrx are 380cc i believe i had to change mine for the same reason.
i would recomend changing fuel pump but i do not think it is essential and could probably wait until after remap

Thanks Johnny...

I have found the fuel pumps brand new for £61.14 inc "Impreza fitting kit", does that sound about right?

What should I expect to pay for injectors (2nd hand)?

johnnyroper

i payed about £70 for a walbro pump so that sounds about right.
second hand price of injectors all depends on what make you go for when i was looking the sti pinks were around the £200-£250 mark i managed to get some sard 650's for about £170 iirc
bear in mind if you uprate the injectors you will need to fit em when at andy's place as it will run like a bag of **** if at all due to overfuelling,he will then put a base map on to get it running and then do the fine tuning.

Yeah, I did wonder about that. I assume the pump would be ok to fit prior to mapping though, I don't really want to lug my tool box all the way up there!

The Injectors might well be a bit to steep for me at the moment...

johnnyroper

fuel pump will be fine to fit prior to map.

i would advise holding off with the mapping until you can get injectors sorted out,otherwise you will end up having to travel to andy's again and pay some more money for a map tweak.
better off getting all the mods you want fitted at once and then pay for 1 mapping session in my opinion that is how i did it.

for that power 440s would be fine at standard pressure, I was running 330 with them,

JamesVTS
