High volume oil pump, I may have one of those but how can I be sure it is high volume by looking at it?

It is physically deeper than a standard unit and uses longer bolts to hold it on. If you have a standard one as well, you will soon notice the difference. Or post a pic, should be able to tell from that.

Would a 202 with it's longer stroke be a better choice with 3.54 diffs or an overdrive (or both) as the engine revs would be lower and the 202 should have more torque?


Cheers, Mick.

In that scenario, then probably yes, the 202 would be a better option. If it were to have standard diff ratios, then the 186 is a freer revving engine and would suit better.

Ummmm, 202's in GTR Toranas were revving freely to over 7000rpm in race engines and for 500 miles at Bathurst.

I understand that and didn't say that a 202 won't rev, but a 186 has less revolving mass and spins up quicker - a freer revving engine, not a higher revving engine.

Looking at getting a 186 to replace the dodgy 202 I got for free cause it's gonna cost me too much to repair but it would still run just needs some money and time. The 186 seems to get a better wrap from everyone in a Landy than the 202 just cause the 186 is a more freely revving motor. Cause I wanna chase foxes and tear around the farm the easier revving motor would suit better and I should be able to extract enough grunt out of it to get the big beast up to speed quick, my rear tyres aren't gonna like me but they won't have a choice being on gravel with a bit extra power Just need someone whose willing to trade a rough 202 for a reasonable 186, shouldn't be too hard

I've got a 173 you can have cheap, - but you'll have to take the rest of the series III it's attached to as well...
