enginerd Posted April 11, 2022 Report Share Posted April 11, 2022 Looking for a working Getrag 260. Also I remember someone saying that there’s a shop who rebuilds them for dirt cheap, if you can remind me the name that would be great!

Dirt cheap is not it, but Walter Motorsports rebuilds them.https://walter-motorsports.com/ Quote Link to comment Share on other sites More sharing options...

Fresh rebuilds are over $3000. We might be forced into an e46 ZF automatic swap just to save money (I don’t actually know what those cost)!!

Double check, but last I looked he was not taking rebuild orders. $1800 is what I was quoted. Condor is $2600-$600 core. I’ve entertained the ZF auto idea. it would be easier to just take the e36/46 G250/ZF310 5sp manual and do a rear axle ratio adjustment (but I know this is not an option with the current rules rules , blah blah blah, perf gain my butt). those G260s are fragile and are getting hard to find. You could always learn how to rebuild and make tools as well. Quote Link to comment Share on other sites More sharing options...

E36 btw. Quote Link to comment Share on other sites More sharing options...

True...let them both in! x-brace = increased chassis rigidity ZF trans = more durable. Less down time for teams = more seat time! sorry...back in topic...g260. But like 5 used ones and build 2 good ones! Edited April 12, 2022 by MichaelPal Quote Link to comment Share on other sites More sharing options...

Would you need the new ratio for the automatic as well? The G250 / ZF310 boxes have a direct dive 5th gear (1:1). Using the 3.73 and 4.10 range as a reference, the equivalent ratio range is 2.93 => 3.25 (these are ratios that BMW made in a 188 ring gear, else you need get super custom). Note: using those transmissions + ratio swap would incur points according to current rules. Quote Link to comment Share on other sites More sharing options...
TimS Posted April 14, 2022 Report Share Posted April 14, 2022 So 1:1 5th gear. I could change the rim and tire size to help solve the gearing issue. We the 3.73 I hardly use 5th. Daytona I needed it but just about everywhere else I have been it was 3rd and 4th. 3.73 with a slightly larger tire would probably be okay? What about the 6spd trans?

You’d have to do the math, but I don’t think a tire rev/mile change will get you as far as you need. ZF6-37 has an overdrive 6th gear. 0.85 (G260 is 0.81) 1 Quote Link to comment Share on other sites More sharing options...

We're probably going to buy a couple on ebay and call it an 'investment' as they can only get more scarce from here, right? The switch to automatic is not something we are seriously considering.

TimS Posted April 14, 2022 Report Share Posted April 14, 2022 The automatic “sounds” like a great deal. No shifting/misshifting, save/gain some points, etc. but the second or third module and wiring to make it work sounds like a big project. Trans costs about the same. Let me know when you figure out how to rebuild the sucker. Quote Link to comment Share on other sites More sharing options...

Looks like 28.5” diameter wheel and tire combo. To match E30 top speed with 3.73 R&P, 26” for same top speed as 4.11 R&P.

Condor does not actually rebuild them in-house, they are sent to a shop in GA(most likely Walters Motorsports). Walters is not taking outside rebuilds last time I spoke with them. We were able to take used 4 cores we had, and make 2 good boxes. The Synchros are usually the fail point, followed by the shift forks once the Synchros fail and are forced into shifts. The good news is all 6 Synchros are the same/interchangeable. So Reverse and 1, 2, usually have minimal wear and can be re-used to combine boxes to a good working unit. We had a local well known shop, Midwest Transmission Center (Hader, MN) rebuild us some. They are a huge shop specializing in manual transmissions, quick turn around, cleaned them up nicely too. Cost was ~$1000 total (500/ea) to turn 4 boxes into 2. Completely disassembled, inspected, combined, reassembled, all new seals, etc. Scott was great guy to deal with and super helpful/knowledgeable and had experience with these g260 in the past. It was getting to be insanity installing unknown used $300-500 boxes in an hoping for the best. Had try something different. Message me if you want more details.

I looked at a swap when we blew up the tranny on the dyno. it was going to be more than rebuilding. I used Metric Mechanic. He's in Missouri so close to you. we had to buy a "new" front housing since we blew a giant hole in it....(effing frightening)... It wasnt cheap, but he does some things to harden it. Worth a discussion for you I'd imagine. I did talk to him about the swap as well... I think all in with the new front housing was 5k. (that included a dual plate racing clutch and pressure plate more appropriate to what the motor is putting out...)... Quote Link to comment Share on other sites More sharing options...

From what I hear, Metric Mechanic is the place to go if you want a quality product. I've chatted with Jim several times over the years about diffs, rockers, etc. He's a wealth of knowledge. All his stuff is so expensive, but I would have complete confidence in his products if I ever pulled the trigger on buying. Actually, the only thing I did buy from him was rocker arms for the m20. He said he bought a few dozen sets of new m20 rockers, inspected them all and measured for slight variations in thickness. I bought a set of rockers (for a substantial markup) that he set aside as "excellent", and ran those in the engine we rebuilt between 2017/2018 seasons. That engine didn't miss a beat and got us top 5 in 9 straight races while revving over 6500 rpm. I might pitch buying one of his transmissions to the team in the offseason Oh, and I discovered what was likely killing our transmissions.... 1) loose / failing pilot bearing 2) problem with the transmission adapter plate causing a slight non-perpendicularity between trans and flywheel. The second issue may have caused the first. 3 Quote Link to comment Share on other sites More sharing options...

II wasn't involved with that decision, and while the shop out there was reputable and the motor feels awesome. after talking to Jim about tranny i wish he had done the work. The guy is old skool and meticulous....a lost art these days... 1 Quote Link to comment Share on other sites More sharing options...
