what size fuel injectors can i upgrade to that will fit in 91 legacy turbo fuel rails .


will 02 wrx injectors and fuel pump work ?

I dont believe they will work - Im not sure exactly what fits into your rails, but you might want to try a search - I know this has been covered a few times...

NOTHING replaces the stock turbo injectors....

You need to swap to different rails and then you can upgrade easily using either STI 550 yellow sidefeeds, or many many different Nissan srd20 injectors.....

I thought the sti yellow sidefeeds were 440??? (sorry to hijack...)

wrx injectors are 440's

what fuel rails do u recomend? how much are they? an is it expensive to get injectors ,pump and rails installed?

or should i just get a fuel cut defender for now?


i dont want 400hp 250-275 hp would be ideal. i will have td04 tmic 2b installed ,and exhaust 2.5" dp is 3" with no cats

is 250-275 reachable with proper tuning? or will i b running realy lean?


someone said they had wrx injectors and they were 416cc ?

it always makes me shake my head when someone talks about putting a td04 on a legacy...

why is that?

The TD04 isn't much of an upgrade for an SS...they are only marginally larger than the VF11


As far as the injectors go, you can get some EJ20G greytops, which flow 440cc, and they will fit in 1990-91 fuel rails, which will bolt onto your intake, but they will just make the motor run rich, and you will still run out of MAF around 15 psi.

So...to make 275 horsepower, you will really need some variety of AFC or piggyback ECU

I'm sorry.....but I'm in a slightly bad mood.....and ALL of these questions have been covered numerous times.
