Good morning RTOC.
I've some how got my car running on efi.
What injectors should I be using? According to Garrett my turbo will be maxed out at 260hp. So was thinking I'd need some injectors for 270hp to be on the safe side just incase it ever gets close. At the mo I'm on some borrowed 802's@3 bar
Try this website fella, it has an injector calculator on it

Did you try those injectors I sent you with the efi kit?
Before trying trying them I sent them to be tested and cleaned but but they where fooked.
According to that website I need. 530cc injectors. ain't that a little large for 270hp
Really??? I never used them, they were bought as a spare setOriginally Posted by Logg

Right just changed it from 80% duty to 100% looks like I need around 425cc for the 270 max.
eBay seems to be full off impeza yellow and Bosch green injectors around that size. Anyone had much dealing with these injectors, which has better spray patterns ect?
Andy I went for Siemens deka 550cc black injectors seem to do the job on mine at the mo mate maybe others could comment but I think the Siemens have a better spray pattern than the Cossie ones mate Found mine brand new on eBay think I stole a brand new set for £150
I had some bosch green EV1 injectors (now for sale), spray pattern is non exsistant just a jet down, but as worked out for around 270 duty cycle is around 100% hence reason of upgrade to 500cc injectors
What numbers on them? Possibly the same 21 turbo injectors I'm running now as they're green. In which case happy days for me
That's rather large Phillip ready for all that boost.

You get light greens (21 turbo) and dark greens (cosworth) I have the dark green injectors
Just had a look at the bosch injectors they have 0280150126 I believe on them.
Dark greens are 803 I think and meant to flow 330ish on cosworths I thought.
This website has them down as 196cc.

BMW 325/528 injectors

They say its 381cc
Yeah 21 turbo injectors cant take that much power, around 200bhp I think it is
Coops is running 802's and seeing 280ish bhp, plenty of other f7p turbo's are around this with 802's aswell
Dale I think that's because on the 21 they only run 2.5 bar fuel pressure but on those 16v turbo conversions they probably wack it up to 3bar if that makes much difference.
