Replace Oil Pump?

[HiFi TSi]

I'm currently rebuilding my motor and I was wondering if it'd be a good idea to throw in a new oil pump? The block had 143k on it and the oil pressure according to the stock gauge was just above the low mark, typical for most DSM's. I know it's not accurate so please don't flame me for this! I'm also installing the b-shaft elimintor kit which should raise the oil pressure a bit. I figure this will help, but it couldn't hurt to replace it anyway and would save time in the long run if it were to go out. But what are the chances it would go especially if I run the car hard this summer? Where would be the best place to get one from? Conicelli? Are there any aftermarket ones that'd be worth while? Thanks for any input.

If you have it apart then replace it. Trust me

One more question. Can just the pump be purchased? I've heard of it coming as the 'front assembly,' which I don't need...

Hmm.. Im trying to remember but from what I recall the oil pump is already in the assembly so you would have to purchase the entire front case. I could be wrong on this though.

I'm assuming that stock is fine and that no aftermarket one is necessary? Come to think of it, I really haven't seen aftermarket oil pumps.

It says on that page.

New Mitsubishi front case with oil pump gears $265 - Engine - 6bolt 7bolt

Recommended when rebuilding a short-block, as it is pretty harsh to lose a fresh engine to a worn oil pump

So with reading that I would believe the pump, gears, and case are all purchased together.

Cool, thanks for the help Larry.
