My new m62! bringing this thread back from the grave

[JGood]

Just google obd-I m62. Tons of info out there. I've never done it.

And modify the cam trigger.

Could you please explain?

broke up with my girlfriend and went to boston to buy a m62.

That's how a project should start, no distractions lol. Good luck!

cool so five speed it is, and all i have to do is weld the brace for the cps on the front timing cover and get the m60 toothed wheel? dosnt seem to bad, thanks for the help.

Ok well I have alot of reading to do, but from my understanding the zf310 is lighter and does not need a modified trans bracket or drive shaft. so iwould like to go with the five speed.

im not going to be dailying the car so i dont thing the extra gear and trouble is worth it.

That is correct. 120lbs vs 90lbs. The 5 speed is 100% bolt-in.

And yes, I'd tend to recommend that option for you. I only switched to a 6 speed because of the fact that I often drive 80+ miles/day, mostly highway. Even with that, the 5 speed wasn't bad paired with the 2.93.

That said, for the 6 speed, the modification to my trans brace took me approximately 15 minutes. And the driveshaft cost $200 total to modify. So it's not like it's THAT hard to do the 6 speed.

First of all, you need to figure out what swap you're doing before you pick a transmission based off of whether it has a hole for a CPS that you may or may not even need.

The only reason you need a hole in the bell housing for the CPS is if you're keeping the engine OBD-II. If you're not, you'll be using an OBD-I harness, and you'll need the crank pulley CPS. That's easy, you just weld a bracket on the timing cover and you're done, and you use whatever trans your heart desires.

Furthermore, the e34 540i 420g's don't have the CPS in the bell housing, so unless you get an e39 420g, you'll be in the same boat as you'd be in with the zf310.

Six speed is easier, all the tricks are known and the resources are developed, including driveshaft, brace, etc. Besides, the m62 is best at low revs, so the six is a must if you intend to drive it on the road at reasonable revs.

The zf310 uses the factory e30 trans brace and a factory e30 driveshaft.

The 420g requires a modified trans brace and a custom driveshaft. I'd hardly consider that easier.

With the 5 speed, you'll want a taller diff... like a 2.79 or 2.93 from an Eta in addition to the trigger wheel setup.

So that's what you're comparing to starting with the 6 speed.

thank you this is what i was looking for

So in the long run what would be the best (easier and cheapest ) route, going with the six speed, bigger heavier need to modify the drive shaft and trans brace, or five speed and changing over the front timing cover for the cps?

I suggest frank's v8 write up as a GREAT resource

damn so now im wondering ifit will just be easier running the 6speed trans? i heard of having to change the timing cover while doing the m60b44 hybrid but never with the five speed.

If you start with an M60, the 5 speed is a non-issue... that may be why you don't hear about it.

Good luck! You won't be disappointed.
