Hi folks, I need some injector advice for my 98 STi. I've done a fair bit of work over this last year to get her back on the road and now I'm nearly done, just got some odds and ends left, ECU purchase and fluids on top of this I need injectors and fuel rails and I'm unsure what to get. I have fitted... Welbro pump, good spark plugs, FPR (adjustable), Tomei FMIC & manifold, HKS SSQ BOV, VF35, usual full exhaust and air filter etc. I would like to get the injectors before I put the engine back in but I've seen so many different types of set ups and conversions! I'm not looking for anything mad or larey, would V5&6 injectors do with a Carl Davey kit? etc. Sorry its long winded explanation of my situation but this is my first real stumbling block as i'm not sure about injectors lol. Any help would be great.

Thanks, J

 

Your standard injectors should be 440cc yellows.. and should flow arounsd 340bhp.. which is in region of max vf35 will flow.. give or take 10bhp..

so probably better to get current injectors cleaned and flow checked etc..

Assuming your FPR id a decent one it should allow the extra 10bhp worth or fuel flow when mapped etc..

ok, thank you.
