After much research, I reckon the easiest way to squeeze horsepower from the M103 engine is to install a Turbo. The Mosselman kit is out due to high costs so I'm going the custom way.

I am looking to improve low-end/off-the-line response and plan to boost no more than 6psi safely. Probably use a small turbo for quick spool up. Some questions for the gurus:

1. Would I need install an intercooler? Temp around here hovers between 90F to 110F year round.

2. Since I plan to run no more than 6psi, would the stock engine management system be able to cope? Perhaps some way to increase fueling on the CIS-E system?

Need some expertise here. Have a nice weekend. Thank you.
