Thanks that's a very kind offer VMAX but just bought a haynes workshop manual off ebay last night

Thanks anyway
Im sure it will be worth the small amount it costs, when stripping the car and when it comes to messing around tuning the engine etc.

If you search on google there is a RAC version which is specific to the 1.6 mk1 which is much easier to use. You can pick it up on Amazon quite cheaply.

Thanks, will wait and see how i get on with the haynes manual first.
May not need it anyway, its just handy to have one there just incase you get stuck with something.

Usually buy one for every project, dont end up using it that much.
Although none of the other projects resulted in complete stripdown.

Thanks mate, loads of good info on the link.
Performance wise, which is the best diff to have the torsen or VLSD? Is there a noticable difference between them?

[trainer]

the torsen diffs are much stronger(300bhp+) and more active but still a road diff the vlsd is ok if it still works only lasts 30k if used hard and won't take more than 200bhp

they come in 3 different ratios 4.30:1 this is standard 1.6 and vlsd also the very rare torsen from a 99 sport with a 5 speed gearbox
And 4.10:1 ratio for 1.8 cars and all other torsens no vlsd
And 3.909 for the 6 speed gearbox

the six speed ratio is a no no you will go know where unless you get a 6 speed box its the same size

so its between the others 4.30:1 will give the best acceleration
however most of the turbo cars go for the longer ratio of the 4.10:1
maybe in a lighter car the longer ratio ie the 1.8 diff with the 1.6 engine

you can buy or source other sized ring and pinions that fit the diff from other mazdas!
i would go for the 1.8 torsen you will need the prop and drive shafts also
they come at a cost i paid £400 pounds for mine complete with shafts and uprights
or stick with what you got until you break it didn't take me long to break my vlsd

I refer you to my earlier post. It is in no way gaurenteed that a JDM car has an LSD as MMC official figures (via mazda uk) show around 50% of JDM cars from 1998 - 2006 as having an LSD.
Try getting an LSD from the main second hand suppliers Autolink of MX5 heaven!
I have found out the hard way it is crucial to ensure the diff you buy is an LSD by inspecting it to confirm this

How much different does a limited slip dif make on the road ? I just pressed ahead and bought a donor, more concerened about general condition of components and price.
