Hi guys, noob here... so bare with me.

i have baught my freinds 2 litre turbo diesel s40 and i usually always have a project build on the go but as i had the free space and got the car so cheap i thought id splash some cash on it for fun over the next 6 months or so and also i havent yet done such a big project on a diesel motor. anyways im basically wanting to get as much power as possible w8thout going down the route of engine swaps.

any ideas on upgrades? i plan on all new forged internals as a precaution as id like to push a fair bit.more power through the 2 litre diesel lump. id like to be hitting the 400bhp mark ( yes i know, a hell of a job but like i said this project is mainly for fun and something to do).

anyways, any ideas for me guys?
