Thanks Weg, i was going to chime in here because I would not be installing a Tii injection system in a car. I’d go EFI. There is so much work involved in the Tii system and then you decide to put a cam in it, it throws the system out of wack. It doesn’t respond well to engine mods. While you can get 130hp out of the engine you are really stuck there for the most part. On a carb’d system you can go bigger Pistons, cam, carbs (32/36, 38/38 or dual dcoe 40s and 45s), Exhaust and you can reliably get 150 hp out of it. Oh and Weg you forgot the Tii brake booster lol. Oh and how much is it to rebuild the Tii Kugelfischer? And no you can’t do it yourself, need special tools and only a few people in the US do it. If you want fuel injection the e30 M10 fuel injection with the 325i throttle body is a much better system that can be had pretty cheap and bolt right on. You still need a controller like a megasquirt but there are plenty out there that run it and it can be tweaked for ITBs and all mods.
