750il 6-Speed Conversion eBay Sale! Rob You're Famous!

[greene08]

It looks here like Koala Motorsport is selling a conversion "package" for anyone interested. Almost seems reasonable, especially if you need a new tranny. Rob it looks like you're mentioned first on there... you're now world famous (if you weren't already)!

See, that's a confusing auction -- they created a "car for sale" auction to sell their services (and not a car).

[greene08]

Yeah, they really needed to just post a service or "part." But I can understand the logic of advertising a "6-speed" 750il.

[SpunkyE30nOk]

65hp gain just be switching trannys and exhaust is a bit out there...Ive never seen such a huge gain from just swapping out those two...but the pic of the twisted shaft is pretty wicked

[greene08]

Rob also honed and polished the intake manifolds, plus the exhaust is a full system. It's very believable on an engine with those physical and mechanical specs.

that makes a little more sense..if thats the case they shouldn't state it as this "Dyno tests showed a 65 rear wheel HP gain with no engine or software modifications on Rob Levinson's car. We swapped out the automatic for a 6spd, and added his Corsa Performance cat back exhaust. (available at extra cost), and got those gains. No other work. Period. " that can be misleading

I vote we elect Rob as our God.

Will anyone second the nomination?

[greene08]

You have a second!

(I do however agree the Dyno placement is a bit misleading)

The exhaust bumped it up a little HP but the 6 spd conversion reduces the parasitic loss of HP to the rear wheels. In other words from the 6 speed conversion, you did not gain horse power from the engine, but you gained application to the rear wheels. you go faster..

I saw that add. I was impessed that the man was in the ad! Very cool. Only 4 huh? Thought there were more. And I was planning on a T56 gm conversion. Oh well.

[sleepy740]

damn thats awesome...
except buy it now is 15k...
i dont think its that much for a 740, is it?

[Auraraptor]

15k is a bit steep, even if the 6spd is brand new, not rebuilt. :confused

With a used trany I would say it should be no more then 4k...what I mean to say is I would only be willing to pay $4k for the conversion provided I had the trany...:embarrasm

[APCR]

Would it be possible to do in an E32 it should be possible but who would do it?

You can't buy a "new" S6S-560G from BMW, the dealer marks it as "remanufactured" -- even if the part is actually new (which it is). The bellhousing then has to be machined so that it will work behind an E38 M73. These cars all get "remanufactured" transmissions, direct from the dealer and then custom machined. Not used.

This is a fairly complex and expensive job. The trans retails for $6.5 grand, and it's not like they're a dime a dozen in junk yards. There's a bit of electrical work that needs to be done, and the (expensive) clutch and flywheel have to be sourced.

Is that conversion available on the E38's??

What did you end up spending on your conversion, and who did the installation?

I'm not sure about the 750 motor, but it won't work on the 740 motor. Someone spent much time doing the research, trying to find a shop to make an adapter, etc and it became too cost prohibitive and just went with the 6spd conversion. You can do a search for it, it was a long one.

[m5james]

It SHOULD be less for the 740 since we share such a similar block between the M62 740 and an S62 M5. From a ballpark of what I've read into this, it'll take about 10k from a shop, and about 6-7k if you source the parts and do the install yourself.

[m5james]

Do you mean can this be done on a 740? Both the 740 and the 750 are E38's mang.

[moroza]

Would it be possible to do in an E32 it should be possible but who would do it?

Anything's possible. With a 750iL, you could get a manual from an earlier 850i, since they shared the M70 engine. Later 850i's (including the 850CSi) had the M73 engine, which may or may not have a different bolt pattern. You may or may not need a custom-made driveshaft, but this to my knowledge is relatively easy to get as far as custom parts go (compared to a custom bellhousing, for instance). I imagine that a performance shop that does transmission work would be willing to undertake such a project, and would likely be able to fabricate the driveshaft as well. Good luck finding a junked 850i, though.

An E32 750iL/6...the next step, of course, would be to swap in the entire drivetrain of an 850CSi - S73 included. :drool:

On another note, what about having a parked faq regarding 7-series manual swaps? I don't own a 7 (yet...), but I'm sure these questions get asked often enough to warrant a sticky.

I was hoping to follow the auction to see what the final figure is. At first I thought it ended at $5400 and I about crapped my pants.

I'd do this on a 750 if I had one. I'd already had my '95 740iL for a long time and the autobox was getting long in the tooth, so rather than throw a bunch of money at it just to have a revived autobox, my tech and I went for the manual swap with the big part, the used tranny, and other bits from a wrecked '00 540. Besides, parts from totalled cars are fun. Just watch Ghost of Flight 401 and think of the possibilities!

I'd sure like to experience the manual with the V12. When my motor finally getting ratty, perhaps I'll contemplate getting the guts out of a wrecked 750 and further bastardizing the Frankensieben. The tranny's different on the 12s, so that'd defeat a fair amount of the benefit, but if I take my time, I'll bet I can get one for cheap enough out of a wrecked 850 and recoup a few bucks out of the V8 manual trans. Sheesh. Suddenly I'm mentally going down that road. Maybe just a little preliminary investigation wouldn't hurt... can't be that hard to do... and I can't see dumping this sled for, well, God knows how long... [hamster wheel begins its sqeaky turning]

[Dave McLaren]

I sourced a bunch of the used parts myself, my tech ordered the rest new as well as sent out the driveshaft for lengthening, and he did the installation. I pulled the whole shebang off for something like 8k. Just use a tranny out of a garden variety wrecked 540. I keep saying this isn't that big of a deal. The ideal time to do this is when your autobox is dying, because you'd otherwise have to spend a wad just to fix it anyway. Rather, you could put that money toward the swap and make it a fun occasion rather than just a pisser.

[JCHenryAIA]

If we can get 30 or more V12 owners to go in for a group buy and get the price under $9K, I would be in.

I am sure Brett would not mind..:D

The 850CSi has an S70, early 850 cars had M70s, post '95 850Ci cars had M73s. The CSi and the M70 powered 850s share the same manual transmission, and it will bolt to any period BMW V12.

you do.




but this to my knowledge is relatively easy to get as far as custom parts go (compared to a custom bellhousing, for instance).


...whether it will hold together is another thing entirely.

It's not really worth it. Various people are grassroots developing forced induction kits for M70s that would likely end up costing a fraction of a used S70.
