914 1.8 Turbo Setup, Questions On a Turbo Setup Options

[modpr2]

I am looking to turbocharge my 75 914 1.8 and need some help. Ive been researching a Megasquirt 2 system and would like to use it to control my fuel injection and ignition timing on my car. I was wondering if i could use my stock F.I. system as my base, so my first question is if anyone has a diagram of the fuel injection system on a 1.8 914. im trying to see what i need to add and what i can delete to work with a turbo. i have alot more questions but ill stick with one at a time to give me time to research and use the wonderful search button. thanks for the help.

When turbocharging an engine, the first rule is to do your homework. Study, read.

Second is to design the system for a purpose. An arbitrary HP rating is not a purpose.
Third is to start small, take baby steps. Start with 3 or 4 psi boost. Check everythnig like EGTs, A/F ratios, etc.
Then bump it up one or two PSI and check everything again.
After a bunch of checking and tweeking and measuring you may hit your mark, or you may stop short for safety reasons, or you may melt parts because you got greedy and took a shortcut.

I had my 2 liter up to 11 psi for a little while, I ended up backing it down to save the motor. I felt it just wouldn't be able to take that much pressure and heat for the long term and stay together.

My 911SC is happy at 8 psi but I usually keep it at 6 psi unless I want to really get after it. I could go higher and impress the heck out of the dyno guy but parts are expensive. I put this engine together to last at least 20 years.
