Question

I am trying to find out the size of the fuel injectors on my MY95 WRX STI RA. I am fitting a Walbro uprated fuel pump and I might change the injectors if they are less that 400cc!!!

Can I tell just by looking at them?

Cheers
Dom.

I have a full decat. exhaust and a K&N induction kit at the moment, I am booked in to have a Link ECU fitted in about a month so I guess larger injectors would be advisable!!

I am also going to fit the uprated fuel pump before the link and there has been quite a few debates that with an uprated fuel pump larger injectors are a waste of time!!

If you can get even 440cc ones (std Sti3/4 then they will make a big difference, 550's are probably the best choice though.

I have been in contact with Mark at www.lateralperformance.co.uk
and he has advised me to go for the 550cc inj, uprated Fuel reg and the Walbro fuel pump!

Bob, I've been trying to see Branko, but we can't seem to find a suitable time! Do you agree with Mark, I want to have the best set up for when you Link my car in March!

Cheers
Dom.

Bob,

I guess I really want to know if I should get the lot, injectors, fuel Reg and fuel pump! I don't want to waste money of stuff, but I do want to have the best setup for when my Link is Mapped!

Cheers
Dom.
