Try Sal Carcellers fuel injection/chip mod with MAF. There is a lot to read up on Sal on Pelican beyond the link below too.
He can adjust the chip maps to your 964 cams, Ben's headers, and octane you want to run (also method of oil cooling).
http://forums.pelicanparts.com/porsche-911...stem-3-2-a.htmlyou might be looking at 250-260hp
I think the whole thing with custom tune cost ~$2K, probably cheaper than cracking open the case.
I also don't think he will help you if your engine is not running right until you get the basics sorted.
Sal has a great system and If I stay motronic, I will buy it. It's ~$2K for his custom MAF, injectors, computer and chip but you still need dyno time to tune it. He sends you updated tune's as you work the engine on the dyno.
I had a MAF conversion on my 2.7 ROW 944 ,you could feel the extra 13hp increase just but the best thing was throttle response without the AFM restriction,the kit came with a cam advance key,custom MAF,DME chip adaptor and custom chip.
With the old DME ECU there is the issue with the boards failing Sal ups the game with rebuilt ecu and improved injectors.
I like the Motronic injection ,simple and easy to sort only issue I ever had was flywheel sensors which can give trouble,I think the OP should consider this system for his engine ,certainly cheaper the increasing displacement as mentioned.
