if its stock it will have a 1200 gearbox, the 1600 will fit straight in however your gearing will be low and u will be revving your engine really high on the highway. i recomend getting a 1500/1600 swing axle box to go with the engine if u put it in. apart from that it should just go in fine as far as i know.

You may have to clearance the gearbox for the 1600 flywheel, and maybe just maybe the starter as well.:o

couldnt you change the fly wheel from your 1200 to t he 1600? leaving the starter as it is and the clearance?

is the car 6v or 12v. i think that makes a difference also? the generator?

How about the physical size of the engine.

Dont you have to cut a bigger space in the engine bay for the 1600 engines?


ColumBUS - January 28th, 2005 at 08:18 AM

no i dont think cutting is required. never heard of it having to happen for a stock 1600.

Ive done it to my '63 which has the original gearbox.

- The transmission bell housing will need to be clearanced if you want to use the 1600 flywheel

- The 1600 flywheel will only work with a 12v starter

- The 1600 flywheel will also need a larger 200mm clutch as the early ones were 180mm. You will need to get a early kombi clutch and pressure plate which is 200mm and suits the early style throwout bearing. The late trannys have a different design of throwout bearing and only work with the late clutches.

- You will need to change the starter bushing in the transmission to a "conversion bushing". It has the outside diameter to fit the early tranny and the inside diameter to fit the later starter

I dont think you can fit a 1200 flywheel to a 1600 crank as they have different types of seals. The 1200 one had a gasket with four holes for the dowels and the 1300 and later have the graphite seal which fit in a little groove in the flywheel.

there is no cutting of bodywork required

The gearing of the early box (4.375 R&P) is actually kind of fun :) Its quite zippy, but I'm only getting about 13L/100km in city driving.

cheers how do i know what a swing axle gear box is


baby_beetle - January 29th, 2005 at 12:38 AM

ya ive done an altinater and a starter moter change i was just worried cause the people at volks west said i will blow ma box to smitherines


Che Castro - January 29th, 2005 at 10:18 AM

Sorry I dont understand what they mean saying your gearbox will blow.

There is absolutely no need to change your gearbox if it is good condition. If you are running a 1200 motor then you are most likely running a 6v starter.


baby_beetle - January 30th, 2005 at 02:06 AM

yer it has a 6 volt but wen i put ma new gear box in it will have a 12 volt starter as i have an altinater.


Che Castro - January 30th, 2005 at 09:52 AM

why are you changing the box?


baby_beetle - February 2nd, 2005 at 08:37 PM

cause the box is a 1200 and ma motor is a 1600cc so im putting a 1500 gearbox in


Che Castro - February 2nd, 2005 at 11:35 PM

its not necessary at all. you can run a 1600 or any motor with a 1200 box fine.
