so I got some work done

got the steeringbox dropped so it will not hit the oilsump anymore
also got the steeringbox connected again to the steeringwheel.
most of the work in the enginebay is done. I got to place the transmission cooler but first need the front bumper for it. I don't have it yet.
and alos need to do some mods to the front suspension top mounts because I'm going to swap to coil overs front and back.

I have the full rear suspension and subframe dropped and dismantled also the donor s600 subframe is a part.
I'm going to use the diff axles and wheelhubs from the s600 in the 190 rear suspensions so need to sort out some thing to make it fit and work good

here is the video

Yes it is a slow revving engine. More isn't always better. The friction and pumping losses in it are significant and the inertial losses are massive. Torque, yes... snappy desire to rev, no.

Your 23 KG estimate is woefully low. You'll find the M120 over 100 KG heavier than the 201's heaviest optioned engine and 170 KG heavier than your current engine.

Compare your 201 tie rods to the 140 tie rods. Now envision having to re-engineer every mechanical part of the car by that factor. Then realize you'd be doing it for a lazy 390 hp.

Hey, its your time and your money. I'm not trying to leave the party with the girl you're interested in, I'm trying to warn you she's a dude.

Sorry I tuned into this one so late. But where have I heard this argument before. I know:

And as of just two weeks ago:

Been running flawlessly for about 8 years now.

The M120 is a great engine for any car. There are better ways to get all out HP but nothing will give you a smooth as glass ride like the M120.

Slow revving? a v12 has 2 times as much ignition every 2 rotation then a 6 cilinder so it would never be
slower revving then a 6 cilinder or 8 cilinder
because of long final gearing of the diff ( 2.65 ) it look like a slow revving engine but it produces 490nm already on
1000rpm and it goes up from there to 580nm stock form

but thanks for your opinion but not going to do something with it

still going to build it

Going to use standalone ecu

Good discussion on engine weights. Se around post 10 for the M120 654lb with all accessories.
