Title: blue/grey Post by: robbzfc58 on August 08, 2004, 08:08:05 AM hi guys to fit a grey gearbox to a blue motor, do i need to change the flywheel(for the sake of the starter motor) if so, do they swap over without drama? dya think the box is strong enough for the extra grunt ...

The actual ring gear of the blue 6 has the same teeth & diameter as a red 6 & a grey. I think the problem would be the larger diameter clutch fouling the bellhousing. You could use the earlier clutch, it should bolt up. Gearbox longevity depends on driving style. Brock & Bond made an Opel 4-sp survive 500 miles at Bathurst in 1970 under racing conditions behind a Harry Firth XU-1 motor. Regards. Dr Terry.

why is it so ??? suggetions please! thanks trev Title: Re: blue/grey Post by: robbzfc58 on August 09, 2004, 08:48:41 AM got it sorted...the prob was the grey starter motor. i did some more measuring & stuffing around & found that a starter from a blue bolts onto a grey bell housing leaving 1 bolt hole unused...guess you guys new that anyway. gave it a run..well worth the stuffing around.
the car was fitted with an ej/eh box with a speco shifter ....it was a pig of a thing ..ive put up with it for 10yrs..very pleased to be rid of it anyone want to buy speco shifter..H pattern ;D cheers trev |
