Hi.
I recently bought myself an W210 300TD 98mod and i am wondering on how i should build it.

I have been reading a lot and i see a lot of builds for high horsepower (500+) but no so many for small horsepower and reliable daily drivers.
I am looking for an reliable 350WHP ore something close to that.

I was thinking an HX35 and 7.5mm pump elements. I have the impression that this is all i need. but i was wondering if i need to upgrade coiling or any other components for increased reliability.
I have been reading there are 2 people who do pump upgrades. "dieselmekn" ore "dieselpumpUK" Any preferences?

I have the standard 4matic transmission that came with the engine.
Is the drive train reliable on this amount of HP?
If not what can i do to upgrade?

Any help is much appreciated.
