Re: 89' M103 Questions?

What does this mean? Why would you need a Diesel cam because you bore the cylinders?

Questions for you:

- why bore the block at all? If you want displacement, look for a 3-liter M103 block and start with that.

- do you know how to enrich the KE-Jetronic system under boost? Do you know how much boost you can safely run without any adjustments to the system?

- do you know where to tap the M103 for an oil supply for the turbo?

Seems to me that unless you really know what you're doing, the first thing you need is an EGT gauge.
