Mid-engine basics
carcentric - 29/10/03 at 08:08 PM

I'm thinking about putting a FWD drivetrain sub-assembly in the rear bulkhead position of my 1950 Morris Minor (about half in the boot and half where the rear seat goes).

I'd be building a custom frame to support the body and offer connections for the drivetrain subframe, and probably using Triumph Spitfire front suspension since I already have several sets from parts cars (that's the locost connection).

Is there any basic stuff to consider other than keeping the (now) rear wheels from steering and routing long coolant lines to a front radiator?

If this has been done, I'd appreciate a link.

Yep, gearchange and handbrake....but all is doable...

There is some reference stuff on my site...

Also, this is very relevant too....

Take a look at an X19, its a Fiat 128 with the engine in the boot

Thanks, Alan and Mark.

Since my wife wants an automatic, I've been considering the torquey Fiero 2.8 V6 as an engine. Actually, '80s Chevy FWD sedans use the same drivetrain and they're both more abundant and less expensive. Might be far too wide for the Minor, though (although fenders are meant for widening . . . ).

With an automatic, shift linkage isn't too tricky, but what DO you do about an emergency brake? Go without? The P in PRNDL would work for parking, but isn't much help in a main brake system failure.

you can buy a single 'spot' caliper (a wilwood part) that you could fit to the upright (assuming its disc brakes?) that work off a cable. You'd need to make up a bracket to mount it...

What does the Fiero do for emergency brake?
Surely it will already have one!


ned - 30/10/03 at 12:50 PM

spyderman,

I'm guessing if he's putting the fwd drivetrain in the rear of acar, the donor would have had its hand brake/emergency brake on its rear axle, hence he needs an alternative.

if that makes sense :s

Alan B - 30/10/03 at 12:59 PM

Terry (spyderman), yes I'm certain that is correct....

Ned, yes that is true also if Carcentric does use an actual FWD unit...however if he uses a Fiero unit that will have the handbrake feature included because Pontiac have already solved the problem when they took it from the front to put in the back...

Did that make sense??

Many, many years ago I had an Alfa Sud.

Was driving around a field, and thought it would be a good idea to try a h/brake turn.

Interesting the front wheels locked up.

That would solve all probs in one go!

If you could find an auto Alfa Sud!

i used to have a car that had front wheel handbrake, nearly stoved it into a curb a few times. Not a clever feature in that instance! cant remember which one it was, though it was manual FWD, and probably last winter. wish i had a memory...

joel

probably an orrible citron bx / cx thing


JoelP - 30/10/03 at 04:52 PM

no. but you've reminded me, it was a xantia 1.8i!! About 400 on an L plate with 30k, which was fairly nice. Shite suspension though, bloody hydraulic schtuff.

Most Subaru's have front parking brake. If my faulty memory recalls...

The mid 80's Subaru XT-6 came in a FWD only flavor and with automatic too.

A friend of mine bought a perfect running specimen with only 50,000 miles for $300 at auction. The car had a number of scratches and 2 broken mirrors and was missing a wheel. It was so expensive to fix those minor items that the insurance company totaled the car! He put a wheel on it, started it up and has been driving it ever since. I wanted to use that boxer engine for my build and he was going to give me that car, but then the MR2 came along and that was free too, but with manual transmission. The rest is history.

A mate of mine used to work for the GPO (when there was such a thing).
One day he has got his boss in with him and decides that he will show him his latest skill of handbrake turns, so speeds off down the carpark, snicks the steering wheel and yanks on the hand brake. His boss promptley disapeared through the windscreen, not a good carear move.
It turns out his new Commer van had a front handbrake.
Maybe dosent help you but it was a good laugh at the time.

i dont think new subarus have front p brake, certainly not the few legacy's and imprezas i've had the priviledge of abusing!


carcentric - 30/10/03 at 11:53 PM

That loud sound you may have heard was my wife reigning me in. When she heard she'd loose the rear seat if I put an engine in that area, she nixed the whole mid-engine idea.

Back to Plan A:


. . . slipping the old RWD GT6 chassis under Moe!

Doc,

I've got a '53 Minor that I've been measuring up for various perverse (motoring) tendancies. Why are you thinking of going with the separate chassis route? There are plenty of people who've stuffed in (as I'm sure you're aware) Fiat's, K-Series, Rover V8's etc but who've just stiffened the basic structure (front cross member from hell and various bits of bracing)

Or is it the pants suspension that's bothering you?

Cheers,

Neil.

1) The Minor's floor is toast and the door to body gap on the left side is non-existent; correct replacement panels would cost more than I paid for the car ($350US). Ditto the brakes, suspension bushings, tires, etc.
2) The GT6's chassis is fully assembled and sorted (I know the engine works with the trans, the differential angle's set, the brakes are mounted, etc.).
3) Having never driven a Minor, I'll have no comparison or sense of loss resulting from a lack of originality.

There's also the Locost Imperative: Use what you already own (in this case the GT6 chassis and several Spitfire parts cars).

Perhaps this project would be easier to conceptualize as a GT6 rebody than as a Morris Minor engine swap! There are pictures HERE

Keep in touch as you go forward with your "newer model."

Looks exciting

Mine belonged to my in-laws and has been dry-stored since 1974. There's only a few spots of rot underneath. The ash-trays are still full of unfiltered cigarette ends and I found a picture in the back that my wife did at play school when she was tiny.

It's an 803cc. I'm still undecided which engine route to go, but the Firebalde-turbo powered MKII Escort at http://www.sitetun.no keeps me awake at night. JLH Morris Minors at http://www.jlhmorrisminors.co.uk/ is doing a flip front and K-Series kits.

Although there's no trim to speak of to 'lose', I'm sure that glass replacement and f/g panels could reduce the weight a bit. I haven't weighed the wheels yet, but they're no featherweights!

Less is more!



Cheers,

Neil.
