Injectors On My Golf

[MK2 GTI]

Hey everyone,
I got a Mk2 GTI with a 2ltr block and a 1.8ltr head on it. I need to know what injectors will fit on em. I tried injectors off a 1.8 turbo and they don't fit. I ended up chucking in injectors off a bmw 323, It runs but it cuts out when ya hit around 5000 rpm. Anyone know the best injectors i can fit on em?

It all depends on what model head and type of injection, more info eh ?
