ts versus 3.0 75 gearbox
Posted: Sun Mar 09, 2008 6:09 am
I have read a lot about the twin spark 75 box being the best box to put in the gtv6
I am about to change my original 2.5 engine to a 3.0l and i am now thinkin should i change my gearbox as well
I have a spare taller 1984 gearbox (According to the chart below)
MPH per 1000 rpms Rpms at 60 mph
[ in 5th gear ]
1981 21.78 2,750
1982 26.14 2,300
1983 26.14 2,300
1984 26.99 2,200
1985 22.17 2,700
1986 21.78 2,750
The question i would like to ask is if i was to put in a milano 3.0 gearbox would my 2.5 clutch assembley bolt straight on(it has the milano single plate anyway)
I have read that the twin sparks cluth and yoke assembly are different does this apply to the 3.0 box aswell I know i will have to change the selector shaft to a splined type (origianl on my gtv)
The reason for my question is i have chance of buying either type of box 3.0 or twin spark but both come without the cluch assembly so im thinkin if the 3.0 needs no mods then i may be bettter buying that
So to sum up
should i go with
the original "tall box
the 3.0
or the twin spark
Again neither has a clutch
Thanks in advance
