Which prop shaft?

gavin_eakins · Postby **gavin_eakins** » Wed Aug 08, 2007 2:34 pm

I understand there are two different sized prop shafts for early MX5s.
My diff flange's adjacent bolt centres are 70mm apart.

The diff is from a 1.8, and is a Torsen if that helps.

Is this the \"big\" or \"small\" prop shaft?
& while you're still reading, what are they worth 2nd hand?

Thanks - Gavin.

You'll need a 1.8 prop shaft. You'll also need 1.8 drive shafts. No idea on cost.

Gavin, as mentioned by JBT you need a 1.8l prop drive shaft and the two drives shafts, assuming you are trying to fit a 1.8l torsen diff to a 1.6l MX-5. The prop shaft and drive shafts from any MX-5 from late 1993 to 2004 should fit.

On the pricing all I can say is that a 1.8l torens diff, with prop shaft and two drive shafts will usually set you back between $1500 and $1800.

Thanks, but it's only the prop shaft itself that I need.
I have the complete 1.8 diff, including drive shafts, and need the bit to put between it and the gearbox.
It's not actually for a MX5, but for a clubman I'm building.

So, the message is "get a 1.8 prop shaft" - thanks!

Gavin.

sounds good, this like a kit car such as the Super 7s?

A Lotus 7 Clubman is usually a kit car.

Same appearance as the Caterham, PRB and Westfield clubbies.

When built yourself to the 'plan' they are often called Locosts.

Look a fair bit like this, but usually don't go as well.

It's more long and short rather than big and small,the 1.8 shaft is shorter than the 1.6.

I could show you photos of it, but you'd only see a pile of tubes sitting on the bench. It'll be something like this when done:
Mine will have a MX5 rear end + box, Duratech 2l up front. About 600kg all up.

Nice colour scheme Gavin

Mines a little older though... built 1965

G'Day Bigdog,

It's interesting comparing the two for proportions. The CMC kit that Tanner used (my photo) has such a higher scuttle / bonnet, where yours is hardly there at all! Your car also looks much narrower. I like the line down the scuttle/bonnet of yours.

To be honest, I chose that photo as just an example - for me, I don't want the aluminium / paint mix, and will go for a block colour. A hot rod mate is trying to convince me to get rid of my planned alloys / licorice strip tyres & install whitewalls + a flame job! At least it'd stand out from most clubmans, where they follow much the same form.

Gavin.

Mine is loosely modelled on a lotus chassis and width is dictated by the diff (BMC A series) on these cars. Engine is 1098cc Ford Anglia, as is gear box. Car was designed and built by Paul Trevethan in melbourne. I found and restored it in 1985 to run in historics. One thing you need on yours is an aero screen - I ran without one at Eastern Creek once and nearly tore my head off when the wind got under my helmet on the straight... :roll:

I understand. As crazy as it might seem, I'm aiming for a "comfy" (!) road car, so I'll be putting a full windscreen + heater + wipers etc. on mine. I get the "tore my head off" bit though - I'm a bike rider more than a car driver.

Your machine sounds really interesting. I bet you have to keep working at it to keep up a reasonable speed.

Redline is 10000rpm, and it spends all day at 8000! 95 engine bhp @ 8000 is pretty cool for a little tiny beasty with no computers or trickery, just good old fashioed points and Weber carbs

It has the best exhaust note this side of an F1 car too...
