The semi-Comprehensive M60b40 into E30 swap Q&A

[The Dark Side of Will]

You suck

If you'd used the site, you'd have seen that there are three listed for $270 in Stockton. :p

You're Welcome

Oh damn! Thank you thank you.

Hey M6x guys, I came across this document with LOTS of detailed technical info on the M62... Thought you guys might find it useful.

Very nice find. I have something similar.on m62tu and vanos ill need to upload.

[VinniE30]

Yeah I was trying to find out the difference in exterior dimensions (length) and weight between the S65 and M62 just out of curiosity. Couldn't find much useful info on that.
But I did find out that they have the same cylinder spacing(center to center).

This?

Came across a reference today to the M62 and S62 using a crank sensor in the bellhousing reading a trigger wheel on the flywheel.

So be careful that your transmission will support the engine management you choose.
I already grabbed a 5 speed, so I'll have to modify the bellhousing to include the crank sensor for my S62 swap.

Also, check out www.car-parts.com for ANY used OE part you might want for swaps like this.

Hello Dark Side. What 5 speed are you using for a s62 swap? I have an e30 m3 with a s52 right now. Bought myself a s62 kit several months ago. I would like to shave any pounds I can + try to make the swap as simple as it can get.

[The Dark Side of Will]

The same S5D-310Z (320Z?) that everyone else is talking about. They were used in '94 & '95 E34 530i. They just have the V8 bellhousing pattern on the front.

What "kit" did you get? What's in it?

[jevijavi]

i have the s62 engine, 6speed transmission, dme, a/c compressor, ews, + flywheel of a 2001 euro m5

[The Dark Side of Will]

Ahh... Ok, you got a complete pullout.

I was thinking "kit" meant mounts, wiring, right selection of hoses, etc.

Top gear in the 5 speed is 1:1, while top gear in the 6 speed is 0.83:1. They both have approximately the same 4.20:1 first gear.

With the 5 speed, you'll need a very tall rear end ratio to keep the RPM down on the highway.

Of course I expect you wouldn't log a lot of highway miles in DomRep.

[jevijavi]

nope not really..i was thinking of using 3.15 from an e36 m3. what could be my topspeed if i used a 5 speed with this diff using the v8 setup?

[mkcman17]

With the 5 speed, you'll need a very tall rear end ratio to keep the RPM down on the highway.

what's the point? i think most of us e30 guys have grown accustomed to cruising 4k at 80mph.

Speak for yourself!

I had a 3.73 mated to a zf320 in my e30 and I HATED it on the highway. My work commute is a 50/50 mix of highway and city driving so it gets old REALLY fast. I can definitely appreciate a lower revving more "refined" highway commute.

[mkcman17]

i think by 'really tall' he's still referring to longer than 2.79 still.

[The Dark Side of Will]

A 4.0-and even more a 4.4-when used with the non-overdrive ZF 5 speed could easily pull 2.56 or taller rear gear in a body as light as the E30. BMW makes them down to 2.35 for European diesel cars.
2.79 is the tallest that's easy to put in an E30 in the US, so we'll roll with that for an example. With the 4.20 first in the ZF and 2.79 rear, the overall ratio in first would be 11.7, which is quite aggressive. A V8 would be able to break tires loose at will in a RWD E30 with that first gear... especially if used with a lightweight flywheel and clutch.
