M60 Swap thread

[LowR3V'in]

Ok I see.

Just looked it up and WOW that's a huge power difference
it makes like 5hp more then an m30. Ouch.

[bmwmech1]

So it's exactly the same just a 3L instead of a 4L?

Yup... well, mostly the same. Smaller bore, intake runners, smaller diameter throttle body, but the main architecture is identical...

im talking about the v8.

So why the solid lifters and a turbo on the B30? It would seem that starting off with a motor that is down on power and throwing boost and solid lifters at it might get you to an even playing field with a B40 with little done to it. Why not just start with a B40 and go from there? You'd be a lot heavier in the wallet, instead of broke with a smaller motor and a lot of money sunk into it. That's the single biggest reason that the motor is ignored and treated like a red-headed stepchild... it's not that the motor is a bad motor. It's the same architecture as the B40, but less displacement will always equal less power, so why start off with less to try to achieve more? You'll always end up sinking tons into a already inferior platform. Dunno, just didn't make much sense to me, that's all. Unless you know something we all are missing...

I beg to differ on B30.
put solid lifters and turbo the motor. It would eat alive any m60 and m62.:finger:

I don't think you're talking about what you think you are. The M60B30 is a V8... I think you're talking about an M30 6cylinder. There would be no reason to put solid lifters in and a turbo on an M60B30 V8. Jean is right in the post above... only good as coffee tables... I just scrapped a B30 block last week... pointless to keep it around.

And put turbo on b40 ? lol b30 is a waste... they are only good for coffee tables and to pull out to replace with b40+

[Paukert11]

The M60B30 is the smaller displacement V8... not desirable, less power
The M60B40 Nikasil larger displacement, but inferior cylinder coating for US High sulfur fuels of the mid 90's
The M60B40 Alusil... desirable due to better cylinder coatings, power output and OBDI engine management

The heads are the same on all of the above and all are OBDI and non-vanos.

OBDII gets into a different type of engine management, which can have it's own challenges, but still usable. There are some early M60B42s that are non-vanos, but the bulk of the OBDII motors are vanos. The preference is for the OBDI motors though...

whats the best m60 to get? it seems like some are better than others. not meaning the alusil ones. are there m60's that came with better heads etc? also whats so hard about stnn up the vanos/non vanos engines?

Garey - you mean e39 manifolds right? 96-99 will work or are they the same as 99-03?

re: driver side mount, it seems that you can keep it on there and just modify it, look at the 300mm.de picture

About re: Yes, that's what I used for reference to modify mine...

Yes, manifolds... sorry. I believe they are all the same for all the years, check realoem to be sure. The drivers side is 4 into 1 and the passenger side is 4 into 2 into 1. I may have them here at the shop or they may be in storage, I can't remember, but I have to run to storage today, so I'll grab them and take a picture for you, so you can see where I cut them off and what they look like. I think I got mine from a Bfc member, iirc. Check my engine swap thread on e30tech, there should be some pictures on there, too...

Yep, he's got a long thread on BFC. I like his swap, other than the way he mounted the engine to the frame rails :/

Saw this thread and thought id share some motivation, its a local guy. I originally picked up a tboned e34 540/6 with intentions of doing the swap but just never went anywhere with it so i sold it to someone with the skills necessary to get the job done. Got a chance to ride in it at our last meet and drive and man is that a fun car.

Never thought of tapping the block... I was going to source the E39 remote filter setup and use that, but this would be better and less expensive... I'll do it this way... what size tap, Lol?

Garey

iirc -10 to 3/4 npt make sure you use a steel fitting
