Kelly, some injector infor for ya :evil:

I got this from the Australian RS boards: No, they aren't the STis, but they are cheaper:
The RX7 series 6 is side feed however are horrifically expensive even 2nd hand. You need the secondary which are 600cc.
Biggest and cheapest Mazda injectors are 12A which are 800cc and around $100 eack s/h.

FWIW, there was a discussion of STi injectors but nothing was mentioned about 800cc STis . . . and these guys know their shit!

You want to put 800cc injectors in your car? Eek, I thought 440's or tops 550's. I've heard that past 600 you may start running into idling problems.

Mark,

Heh, that's what I was thinkin. A better idea might be to run some 440cc primaries and 380-400cc secondaries . . . If you really need that much fuel . . .

[kelley]

thanks for the info boost junkie. I'll look into that. some nissan's also have side feed that might work.
560's are fine for maybe 350hp. but I need more fuel for more power. idleing has to do with engine management and tuning. you're right if you drop in 800cc injectors in your stock legacy it will not idle very well or at all.

[boostjunkie]

However, even with proper engine management, injectors as big as 800ccs will not produce a good idle. They just can't open and close fast enough at the lower rpm range. Sure, it can work, but it's nothing I'd consider as a "comfortable" daily driver.

You might also look into this. It's an extra injector plate setup. You might be able to contact the guy about a custom setup:
