I'm having a FD transmission built by Liberty Transmission in Michigan. They are shot peening, heat stress relieving and cryo treating the gears. My second used transmission is about to let go in my 3 rotor. Neither trans was in good shape when I started though. I can give some updates when I get it installed. It could be a cheaper alternative (although not too much) if it holds up. However, I've had to spend some cash on a cluster gear since the original one was twisted.

It will need new mounting holes drilled to match the auto bellhousing.

Tranny is doing great. Working out of town the past year has put a limit on drive time. I only get to go home 4 days a month which sucks. The reverse grind has stopped now, after re-adjusting the clutch. The last few months I've mainly been tuning for e85. I've only put on less than 700 miles this year. I havn't done a mileage check yet.

The starter on the fd bellhousing is in the way to go that route. There was somebody a while back who was talking about using a custom longer input shaft and a 4" adapter to clear the starter and put a Camaro t-56. I don't know what ever happend to the thread.

Also Spec do a custom clutch kit for this conversion which includes a twin min carbon cerametallic clutch and fly wheel for about $1300, its should be a nice bit of kit as the clutch disck's are made from the the same material as threre spec stage 3+ clutchs which i use to have on my fd and it was like a stock car.

I have a kit that I purchased wile back,
it comes with machined auto bell housing, tilton throwout bearing, spec twin clutch & fly wheel, custom adapter plate & starter, I think all I need is the mount, drive shaft & the T56 box If I use it on my fd,
I also have the C series b20 shaft & center iron with with new FD rotors and used housings, few more things to put it togeather,
cant make up my mind yet on what car should I run this setup,
I am also considering selling the whole setup to free some room
for other projects
not sure where do I post if I deside to sell,
IronMdnX keep us updated please on the durability of the t56

I know G-Force makes a 1-4 triple syncro conversion, anyone know the price?

Places sell a kit to upgrade the output shaft. It includes a modified extention housing with larger bearing and a shortened viper shaft. Another option is the SSR output shaft wich is larger 32 spline. Also Gforce has upgraded shafts availible.

FD > FB > FC
dang that GTO tranny is a near perfect fit! How well does it shift with the plastic surround on? Does the shifter ever come in contact with the plastic srround in any of the gears?
Does the boot ever pop off the shifter in any gear?
Reason why I ask, is it looks like the GTO shifter sits JUSST a little furthert back than the FD one.

The shifter is about .5 to .75 inch further back. In 6th gear it does touch the plastic retainer for the shift boot, but works fine. In the picture of the interior the tranny was held up by a jack. The tranny sits lower now after the rear made.
The E-saft broke at just over 6k rpm in 3rd at 25.5 psi boost. I'm sure it was flex, the assembly was never balanced. Power should be up there it is an 80mm turbo maxed out.
