Am looking to upgrade my injectors on MY99uk along with the following mods:

VF34 Turbo
Uprated Fuel Pump
Tek3 re-map

Which injectors do I need? Have heard quite a few variations eg. 440cc, 550cc, 565cc, pink, phase1, phase 2....etc.

Straight forward fitting?

What power are you after? Somewhere between 300 and 350 will be available on your stock phase 2 440cc injectors.

Am after over 300bhp but under 350bhp...so should be okay or best to change?

I'd suggest you're OK - spend the money on an uprated FPR instead, there have been some reported cases of an uprated pump overloading the OE regulator (although mine has been fine)....and if you find yourself short of IDC's yoou can up the pressure a little.

Discuss with your tuner to see their preference.

I was getting @320bhp./290lbs/ft Nicely drivable.

With this Turbo/440s.

I do have a FMIC and BLITZ LM induction

The FMIC shouldn't be necessary.(Especially now its getting colder)

Do have uprated fuel p/p.

My car had to have mapped in Knock correction.( Due to my ECU )

Again you should have no problems,with UK car.

Steve,

your twisting my arm...320bhp/290t sounds v tempting. Still its a very slippery slope at 2k!

Been told by TSL that even with better injectors, anything over 300bhp may be risky as the pistons would be the weakest link.

They did recommend I upgrade the injectors, but now I'm unsure as how much BHP to ask for

Best in this situation is to go with what your tuner recommends - I've never remapped a classic on a vf34 so cannot speak with any authority.

Mark from EMS (EcuTek tuner in Holland) has I believe, maybe worth emailing him for more info.
