Just wondering if anyone has replaced their injectors and fuel rail from side feed 2 top feed?

I've heard that Mazda 13B s6 injectors and a custom fuel rail can be modified 2 fit the RB25.

Does anyone know any more about injector upgrades?

Does it work out cheaper than aftermarket rb25 injectors etc?

Akira,

Mark at Hills is sourcing me some 680cc injectors (brand new ones) I can't think of the brand or price off the top of my head, but when i go to see him next week re. my new turbo, i will get some details for you.

i need a phat fuel pump too.

Sweet, I have no idea what brand half the stuff on my car is .... although my fuel pump makes a cool "bbrrrrrrrrrrrrbepp" noise on startup :P I'm hoping to use Mark's services for a few things in early July, do you think for a price he'd be able ot show me where half the aftermarket mods on my car are and what type they are etc ?

Jimbo,

Please give me a PM Re: 550cc injectors. R they side feed or top feed?

Prank,

I,m currently upgrading my fuel pump 2 a GTR internal item. Can always add external pump and surge tank later if required, but GTR pump is doing fine on current set up.

What fuel pump do U intend 2 run?

Prank.

I was going to run something like a bosch motorsport unit in my car although my friend uses a HKS Pump which he believes is around 100-200 extra.

Meggala: thanks for the info about the 33's i always thought that anything over 200kw was requiring some fuel system upgrades.

I plan to do my injectors and pump when i fit my turbo...

Decisions decisions
