Just finishing off my zetec turbo build and planning on getting the car mapped and set up in the next few weeks.

In not sure what size injectors to use, I plan on running around 350bhp. I was thinking of using 550cc Bosch VE14 high Impedance Injectors but wasn't sure if they'd flow enough fuel? or would I be better with 650cc, 750cc?

Thanks rob

 

Speak to your mapper. They should advise.

Mine did 293bhp (flywheel) with Siemens deka 1V 630cc and afaik they had some headroom.

 

550 will do 350hp ok.

The 600-660 Siemens are dirt cheap and excellent though and will give you headroom for more power if you need later on.

Of course as with anything good and popular these days, there are Chinese copies everywhere !

 

I went with Siemens 630cc, less money and I won't be pushing them to there maximum limit
