I believe you will also need the CV joints as the 968 CV's were different lengths. The mount for the 968 and 951 transmission (I believe) may be different as well. Besides that, I cant think of anything else you would need.

Fox the CV I will order GkN motorsport axle , and as for mount I will need to find out

Hope all the shift linkage will be similar

But I think I will wait until I get a right LSD install and swap all at once
Right now I will just try to live with close ratio 6mt

Yeah, Im not sure about the shifter linkage either. I thought there was one or two guys on this forum with 968s. Hopefully they will chime in soon?

You will need the Torque tube, Transmission, shifter linkage(the tube part), and the mount. You will need to make spacers for the transmission mount as well. It needs to be spaced down about an inch.

Thanks every one for help

I already bought two 951 transaxle one with cooler one without , In my country there are less then 20 951 exist so I better stack my own spare part

one 944 torque tube , shift linkage and mount , only thing I need is Motorsport axle and LSD

You talk about a six speed track car, the 951 transmission is 5 speed unless my 951 transmission has a hidden gear somewhere.

I wish I can find a missing gear too

finally recive my long wait porsche 968 from state


i love the idea of german chassic and LS1 power car !!!

however i have issue of car runing hot on water. after the warm out the temp show on stock on gauge is pretty high above 1/3 upper part if i did some wot test the temp will rise to redzone....

which bother me a bit.. any idea what kind of radiator i can be use ?

since i am all the here at asia i cant just order part fom summit or jeg

so i would like know the size of radiator, that i can have shop build one here

thanks for your time

Sounds like you have air in the system. Remove the small hose from the front on drivers side head, remove the radiator cap and put the small hose into reservoir and run engine. You might have to do this for several minutes and rev the engine to move any tapped air. Engine should run between first and second lines on the gauge when bled properly.

This is what I plan to do next

The shop who did the install

Have a vale on one of heater line , I think this is for bleeding air


But in the hot weatther where I live (100+f) I think bigger radiator is need it


J

Bleeding system three time in 2 days. the water temp seen to be stable a bit

will drive it tonight to find out





next week will go to friend place to make trul dual with crossover pipe

the current set up. is cat back with 968 factory system... i can only say it is really quite !!!

and people will think you have a lot of missfire in your engine instead having V8........

before that will do a dyno pull to see how many horse i get under bonnet

i have LS1 engine with TR 224 cam and the support mod but with untune ecu. i am hopping aleast get 340whp from bosch roller dyno !!

J

this week will target on new exhaust system



my high flow cat. i try to find out the smallest i can fit under so i dont have too much restriction




most of piping. the muffler is going to made by my application

compare to my stock 968 catback now

new system should be very promising !!! either in sound or performance

Looks like a very nice swap! Let us know how the exhaust works out. It should make a big difference!

some update of the exhaust

just mocking out the posion.... so far so good

2.5 inch SS pipe all the way with Vband




Final part of welding





how to muffler look from the side

Really nice job, is that the x-pipe under the tunnel brace or just how the two exhausts were routed?
