v6 conversion

[BradGTV]

Hi guys, ive been busy latley 
my dad and i have bought a 164 which came with x2 3.0 engines and a 2.5 engine,
and we bought a 2.0 twinspark today.

because we got the spare 2.5 it has all the parts for a rear wheels drive 3.0 conversion. so the gtv6 will be untouched. and the gtv will recive the 3.0 engine and twinspark gearbox.

is the twinspark gearbox a bolt in type conversion? and the twinspark has new dounts - do 75 twinspark donuts go onto a gtv driveshaft?
cheers, Brad

Perhaps the question you should be asking is does a gtv driveshaft go onto a V6 flywheel....

perhaps 
i just ashumed it would, does it?

thanks choderboy,
do you know if the shafts are the same lenght? (gtv and gtv6)
is the reason they dont fit the donut pcd?
worst case senario i make a totally new shaft like MD's design.
cheers, Brad

ok ill start again 

so your saying a 4cyl donut will not go onto a v6 flywheel, yes?

what i want to know is if i have a 3.0 164 v6 up front, with a twinspark gearbox at the back, what *options* of driveshaft do i have?

cheers, Brad

Brad - do we assume you have the GTV6 flywheel?  You'll need to use that on the 164 engine, along with pretty much evrything else apart from the block and heads.  Including changing the oil pump, the distributor drive, the water pump, the sump, the ..... Well, everything other than the block and heads! 

You'll also need to have a 4mm spacer made up to fit between the flywheel and the back of the crank (164 and GTV6 blocks are different lengths), open up a number of mounting holes in the sump and so on.

If you plan on running an engine management system with a crank angle sensor keep the 164 water pump and front pully. The toothed 164 crank pully will not fit unless you have the 164 water pump. Very annoying.
