Default 6 speed....

Is there a company that sells everything to convert an automatic 85 to a 6 speed? I have also heard a rumor that a 6speed from an ls1 will work too so anything about that would be helpful! I need the knowledge of the veteran vette guys on this one. Thanks ahead of time

Thank you very much! I think the keisler looks like it could be the cheaper way to go because it comes with everything i could need except for the center consol which i will make out of aluminum anyways!

I'd imagine it would be easier to sell the automatic and buy a manual.

This is not true, and, the reason I have been putting off my swap for quite some time. Give them a call, what is shown on their website is only an enticer!. You'll also need torque arm, pedals, complete clutch assy, bellhousing, and all hydraulic clutch components. Original deal sours when u have to add all the periphials.

Since I have done both swaps, I know a little about both.....this is just off the top of my head....


You need the same parts either way... but the ZF is notorious for being noisy and if it ever breaks, it is $2000 minmum to repair, or you can buy another cheaper if they are still around since they are discontinued, and the clutch parts are limited in terms of different mfg'rs and the clutch parts are costly

to do a TKO swap

For a TKO swap, all you need is a
stock 84-88 Clutch $ 300
stock Bellhousing 84-88 = $125
Stock 84-88 master and slave $100 total for both
A Dakota Digital Speedo corrector, you can buy your own or buy it thru Keisler $75
It comes with all mounting brackets and shifter and drive shaft yoke.

http://www.keislerauto.com/gm/corvet...page_tabs.html


to do a ZF swap, you need a
89-96 Clutch @ cost of @ $450
ZF Bell housing = $300 (IF YOU CAN FIND ONE)
a ZFsingle mass Flywheel = $400
or a Dual Mass Flywheel = $1000
ZF Slave and master = $125 for both
ZF Drive shaft yoke = Junkyard $50
Speedo Corrector = $75
Small starter

email me and I will send you a copy of my old quote from a couple years back

Yes they have the TKO 600 believe is called.
And also JustVettes in St Charles MO will have the pedel and rest stuff you need a console stuff but recomend you buy it from a place like Corvette central.

While I really like ur product, I have to say someone in your organization does not have the facts. I inquired in 2008 and again 3 weeks ago. Your web site for the C4 shows everything included, but the quotes do not. I asked here, on the Forum in 2008 and you (not you personally, but Keisler) stated that I needed a torque arm, pedals, and a driveshaft from an 84-88 manual car (my car is an 88). Both quotes did not include a bellhousing or any of the hydraulics or clutch components. The last quote did give an additional price for an upgraded clutch disk,
by itself. In my recent emails with your company, I was advised I "could" purchase the Keisler hydraulics, and rig them to work, but it was recommended I use stock components.
I have recently aquired the above mentioned clutch, bellhousing and hydraulics, $500 dollars through ebay, not incuding S&H.

Again, I like ur product, and admit I have not been in any hurry to get my swap done; but, I do still plan to purchase, and feel it is only fair to be accurate.

To the OP, u do realize this is gonna be at least a $4000 project, and that's if u do ur own work? What is the worth of your car, and is it cost effective to do this swap? I know, in my case, I have already invested (ie: dumped ) a stupid amount in my car, so the answer for me is "probably" . Also before u buy from any of the above mentioned companies, ask specific questions about what is specifically included in the kit u are quoted. I think u'll find no one includes the clutch compnents, bell housing, hydraulics, drive shaft,pedals, console, &tqe arm: and, that the kit includes only "basic components" needed to start the conversion.

To LD 85, I have followed ur posts over the last years with great interest and bow to ur first hand experience, but, wasn't your swap from an original manual car to uprade first to a ZF and then to the Keisler TKO? This makes a difference in what the OP is needing to complete his swap. If I am wrong, I apologize in advance, but I am reporting what I personally have encountered while saving up and gathering parts for this same type of swap. I think we both do agree, a Keisler or similar TKO swap is better in the long run, than a standard ZF swap. Tom

zo1#316 thank for your help! Like you i am not really in a rush i willl just have the money to do it this summer while on break from college. LD85 has been helping me a TON and has already found me a bell housing. I will get all of the other parts from a C4 grave yard in san antonio TX (home town). Im doing this swap because i am building this car for road racing and it will still be fun to take to the 1/4 every once in a while, plus the worth of the car has no limit to me
Thanks again for all of your help!
