    Howdy from Colorado. Anyone have a source for replacement ring & pinions.?
    I've got the wrong rear end gearing currently in my Lotus powered Hillman Husky.
    Current rear is out of a Hillman Minx.
    Having a hard time on 1st gear starts. Gotta slide the clutch quite a bit with lots of revs.

    Cheers,
    Cris

    Minx' were never geared higher than Alpines. Even if you have the highest stock ratio found in Alpines, 3.89, I'm surprised you're having difficulty with first gear starts with the presumably extra HP from a Lotus engine. The problem might be elsewhere. At the very least, take it apart and find out what ratio you currently have. You shouldn't need stump-pulling 4.55's out of another Husky to get the acceleration you want.

    Cris,

    Is there any chance your brakes are hanging on and dragging? It's a problem that pops up on occasion due to failing brake flex hoses.

    The only limited slip chunks that I know about were essentially prototypes, built for the Rootes racing program. There was never a production unit available to my knowledge.

    I believe the gearing I'm running now is the 3.89. I think if I had a 4.22 I'd be dead nutz with less to overcome on initial take off.

    Sounds like you have a narrow-ratio transmission.

    Find a SV rear assy(4:22) and swap. The SV's are a bit stronger than earlier series also.

    I have a 4.55 I could part with (Came in my alpine, I swapped it for a 3.89)

    Cris,

    You are saying the gearing is to tall for the motor to get off the line...? I'm very confused by that...

    The tallest geared alpine was a S3 with a close ratio trans and 3.89 and even with the 1592 you can start them in 2nd with minimal clutch work...

    If your car is lotus powered what trans is in it? Jensen healeys had a lotus twink with a rootes arrow range trans... What are you running? The ford derived 4 or 5 speed per the elan?

    What ratio is 1st?... As discussed the next ratios are 4.22 then the delivery van ratios.... Unless you have a 5 speed box or tall wheel tyre combo.. Youll end up with a hill climb car....
