g60 one is same as the normal mk2 one, its the injectors that differ. summut out of a porche or aftermarket is wat u want. are you going to get the ecu remapped to suit though, as just doing that on its own wont get you anywhere!

you can fit a riseing rate FPR  they help digi 2 engines, shoveing one in thats just a higher pressure is a bad idea   it'll get more fuel EVERYWHERE   thats awhat we did to TC's motor  but it makes it run excessivly rich on cold start and it has caused a bit of a torque hole but it can be driven through and the coldstart / idel dosnt really matter as it's a track car,  bad idea on a daily tho

What ARE 'the fueling issues'?

I just meant that they all do it incase you didn't know, rather than thinking yours alone has a problem :wink:

Neither of your suggested fixes are going to work properly, they will just make the mixtures wrong everywhere else (ie, where you actually use your engine), the real cure is a re-map though thats not a simple thing to do apparently. DannyP's suggestion might improve things a tad but its not the solution. Your only real option is to find someone to do you a custom chip or swap to a different injection setup though if you go the chip route Id wait till you put a better cam in there (Im assuming that since you didnt mention it you havent swapped the stock one out yet).
