Austin 1300GT (not mini) pre verto flywheel
Turbo Mini Forums

I have a pre verto flywheel from a pre A+ engine from an Austin 1300GT.

The flywheel is 25mm thick, where the standard mini one is 19mm thick.

I've been trying to assemble it with the standard backplate, but for obvious reasons this is giving me no travel on the clutch.

Did these flywheels have extra spacers or something to get the straps and preasure plate away from the flywheel face or should it have longer mounting lugs on the back plate?

Throw it in the bin immediately! Fit a Mini one.

The only difference should be the large ring. Everything else should be equal.

Would you be able to elaborate please V?

If something is worth doing, it's worth doing half of.

Thinking about it, the GT one is about 30% thicker, so probably has around 30% more weight to it. Can't be good for the engine to try and spin that extra mass.

There is a big "ring" on the flywheel to add weight. The very least you should do is to remove this in a lathe. Heavy flywheels on a Mini/ADO16 is a nono.

So it's ripe for lightening for future budget build projects then....

I threw one of these away about a year ago - as V says there is (was) a massive ring of extra material hanging out the back to increase weight and polar inertia.

It was also the old two part design (6 bolts holding the wheel to a seperate hub) but, in my case, the backplate was the same as normal..... it must be, it's in my engine, only mods being machining the lugs down a small bit to get the spring flat......

Schrödinger's cat - so which one am I ???

I thought that was the case when I measured it last night...

I think I will keep it and see about getting it machined down at some point, but only if it works out cheaper than buying one of the minispares lightened jobies

EDIT: Horrendous Spelling!

Fair point.....

Bin, bin, bin, bin!

I thought BIN meant Buy It Now?
Do you want it V?

It will go on the scrap pile, minus it's ring gear....

there is nothnig wrong with a safely modified cast flywheel,
Andy,keep it for emergencies,

use it as a doorstop

Buy another one and stick em on the end of your press bar

I was lucky my friendly machinist took the extra ring off mine for me as a favour,

The 1300 gt block, as per vizard, is a stronger block however as it doesn't have the little square out above the center main however, if you are sticking with the A-series block and 1300 gt crank...

You could make use of the standard duplex timming gear however if you are on a budget, but use a tensioner and offset keys :)

Interstingly the 1300gt head does make a nice instant bolt on addition to the a-series 1000's and 1100's as it increases the cr and has bigger valves (that don't require the block to be pocketed, just 1275 head gasket and rocker gear spacing) and has nice open chamber and port profile, infact probably as good as a cooper head.

Would recommend a 1 and 3/4 inch card on an alloy inlet with an lcb and k&n probably worth about 30% power increase if set up correctly .

Cheers

BTW - I took my buddy VTEC Pete out for a spin this weekend, and even though I am running her in, he gave it a name, the "Brocket"...cause I'm a brocket maaannn, nah nah nah nah nah nah nah nah nah nah nah....

Let's make sure you embarrass at least one VTEC MINI today !

Interesting points about the engine Brocky. It's in bits in my shed....

Never had the head though. Timing gear is on the metro van's engine (with offset key and tensionor).

I had a look at the flywheel last night, the extra mass looks to have been riveted to the thinner type of wheel. As it's scrap, I may well have a go at removing the rivetts and see what happens.

When John brings my puller back, I'll put some pic's up next to a standard fly for future referance.

Carl - you never know, it may well come your way for some work at some point...

Yep your right V I was thinking of the standard 1300 saloon engine....:)

I dropped a standard 1300 head on my 1100 and it worked really well. :)

You were lucky then. I guess you used a standard cam??

just been offered a 13gt block at 73.5mm and some forged omega's to match, £250,
is it worth getting?
can i fit A+ rod's and crank in there?
and what else wont fit?
ta

Everything fits.

I finally got round to giving this to Carl for machining. The finished article looks pretty good to me.





Originally it was pretty much flush with the centre piece so there's a fair amount of metal removed.

Who needs timing marks anyway
