fuel mgmt on 1.8

What are you guys using on your obd1 1.8 dohc motors for fuel management? (95 and older 318is etc)

What upgrades are there available for injectors?

I just picked up a 93' 318is on craigs for a hell of a deal. I have an old supercoupe blower (m90) just sitting around my garage. If my memory is correct it will put out (with the stock pully) 12 psi, so not quite 1 bar. So i am also curious on how much power this drivetrain can take, as in what is the tq rating on the transmission, rear diff etc? Also what are the internals like on the 1.8 dohc motor i have, forged anything? Rods? crank? pistons? how much can the stock motor take without blowing up basically?

Thanks in advance. (btw i want to keep the 1.8 i do not want to go m3 or s52 m50 or m52 swap- i have my reasons so can we keep the topic on the 1.8 please)

Whats Forged and Fuel

The crank & connecting Rods are forged, I have been told not to go over 10 psi of boost, I have seen up to 15 psi on stock motor don't know if it lasted or not. for fuel i would look into an emulator from Welcome to www.moates.net! : Moates.Net and a chip burner. with this setup you can still take it to be tune on a dyno by a professional (recommended) and keep the file and burn it in your chip when you get home. Look at the ostrich 2.0 if your ECU is a 282 then you have more options then I with a 990 but an emulator looks like the best thing going as far as bang for the buck and only if it is a street machine. if it is going to be a race car go MegaSquirt or if it is going to be a fully built motor. hope this helps a little.
