Getting torque from M52

This is what I'm afraid it's going to come down to.

I'm already planning to make a remote oil filter housing (Could buy one for $500, but that's 3/4 what I got this truck for) so I can free up some room for belts to mount an Eaton under the intake.

Still open to easier bolt ons to get more TQ. I feel like a black sheep wanting more TQ and not sacrificing it for HP.

Didn't they have a model that used a BMW V8? What trans is in it? The factory Rover one?

~2000 Range Rover Sports got the M62B44. That's too new. The trans in mine is a beefed up 4hp22, used up until around 2000 in every Disco/RR. Simple bellhousing swap and BAM, can fit an M52, or M30, or M70. M60 won't fit because they never mated M60s to 4hp22s. Could use a trans from a 740, but then the tail shaft will be different and making the transfer case work will be a pain.

They did use M52s in 1997-2000 South African Defenders.

Took this thing offroading and it just lacked more than I thought it would.

Also, I'm pretty much stuck with this engine. Nothing else will really fit my application without way too much work (limited by transmission bellhousing options) otherwise this thing would be getting an M60B40.

Would it be prudent to swap to OBD1 intake mani? S52 cams? Everything seems to decrease torque in favor of high end hp.

I've done both of these to mine, though I haven't put it on a dyno to see how much of a difference they made over stock. It's my understanding though that both, as you mentioned, do in fact result in more high end HP while sacrificing some of the low end torque.

Talk to me. Anytime I search all I get are torque specs. :hitler:

I want more low end TQ. HP, meh, not too worried, I'm lugging around 4600lbs with this engine. Up mountains, over rocks, through water, yaddah, yaddah....

Background:

OBD1 M52B28. Retained the OBD2 manifold. Using OBD1 throttle.
