Allright - this is an old thread, but I wonder if these guys are wiser now, because I could use some advise.
I have a 155 V6, which I am about to "tighten up". The 12v moves out and in comes a V6-engine and 6-speed gearbox from a 156.
I have mounted a Q2-diff. but now I face the difference between the differential cover for the 6 speed gearbox and the old 5 speed gearbox. The nylon driveshaft for the speedometer is placed in the differential cover in the 5 speed gearbox, but in the 156 the speedometer is driven by signals from the ABS-system.
Meanwhile the die-casting in the differential cover for the nylon gear is unchanged from the 5 speed gearbox, but the holes in the material was not made.
It's not possible to use the old differential cover, as the space for the spurgear is smaller than in the 6 speed gearbox. With expected engine power I'd better take the wider one.
Does anyone know if there is a differential cover with space for the wider spurgear AND for the old type nylon gear for the speedometer? GTV '95-'97 maybe?
Has anyone got the lacking holes made by specialists?
I have considered to use pulses from a ABS sensor from one wheel. My profession is electronics so maybe I just need to make an electronic divider for the ABS pulses to a slower rate like the ones from the nylon gear. Anyone been there or have better ideas?
Arhh - realise that I mixed names for parts. The bellhouse is of course the house where the clutch lives. Have replaced bellhouse with differential cover. Pardon
