as title what engine would you fit and why i have the choice of carb or pay 300 more for injection

Injection because with a power commander, it will be easier to pass emmissions.
Carbs require re-jetting and an air bleed system into the inlet to weaken the mixture to allow a pass.

Carbed R1s don't need an air bleed system to pass emissions. You adjust the idle mixture screw until you get to stoichiometric and the cat cleans up the rest.

You have to re-jet a carbed engine or power command an EFI engine. Its all about the same. EFI engines have to have a fuel return pipe and a higher pressure fuel pump but it's not much more work. The EFI engines are said to be smoother and perhaps have a few more BHP. Either are good.

Personally I'd have the fuel injected engine but I found a carbed engine cheap and its just fine.

will i need a check after having engine fitted and got 1.6 xflow ford at mo

carb although slightly down on power (nothing to much noticeable) delivers its power more raw!!!

what do you mean by check?

I would go injection as they have to be easier to set up and probably more economical. It must be far easier to setup a power commander than fiddling with jets and power commander is more adjustable over the entire rev range were as with carbs you only have low mid and high to adjust.

power wise the early R1 carb and injected were virtually the same at approx 150bhp. Later 2004 on R1 engines are different and produce around 180bhp

If your car is already SVA'd then you will not need another, if that's what you mean by 'check'

As I understand it, the 05 injection onwards is 182bhp but this cannot be acheived in a car as ram air only works over 130mph.
However, this has not stopped me from trying as I am installing 2 NACA ducts on either side of the MotaLeira with 3" pipes to the underside of the standard airbox.
I figure that it has got to help!
