Hello there out a rather small country called: Holland (NL)

Rear axle needs some mechanical empathy. You can drive around the weaknesses of the axle if you are gentle with regard to shock loads. We do and its still alive...so far.

If you don't want to wait 2 months for parts then the 86 probably isn't the best of cars. Engine and suspension parts for the 86 are available everywhere. Just type 4age into ebay.co.uk or google for MCNsports of megan racing etc.
The difficult part is the little parts of trim etc that you'll need all around the car. So you're not gaining much by the Nissan conversion.

don't get me wrong...

If the 86 came to me in a reasonable standard condition

I would probably put a 4AGE engine in...

I only have a rolling shell...

And nearly everything needs an overhaul, or redoing...

This'll be a long project...

Rust is primary, as mentioned before...

After that I'm going to attempt to acquire a good weight of the stripped chassis...

So I can determine the CoG (Center of gravity) of the chassis (for my, already prepped files) to end up (once I've acquired the other CoGs of the parts) with a reasonable approximation of steering characteristics, forces (lateral, longitudinal, vertical, etc), loads strains, etc.

Or if any of you have X,Y,Z coordinates of parts, weight distribution, etc ... I can already produce some (fun) graphs which chart the theoretical steering behavior of your car... (depending on the stiffness of things like tyres, bushings, springs and dampeners)

I'll try to post an example of the steering characteristics graph later this evening if you're interested...

This was done Using data found here...

Solely stock 86 (coupe) figures...

[NoHachi]

Some units along those axes would help :wink:

If you determine the stock chassis COG height (use the tip-over point method, not the scales+angle one), I can give you the weight of most other important bits in the car. You can get an idea of locations from some of the cutaway / cross section drawings circulating on the interwebs (model car related, but its close enough).

[CA86]

Yes, the units would help

realised it just after uploading it... *doh*

Actually the method to chart this is rather unsatisfying.

The values needed are determined, are not mathematically founded in any way... Believe me, Ive tried to find someone who could give me more information about it, but sadly no luck

This graph is mainly used to give a estimate about the dynamic behavior of the car...

But as you all know... this is a purely theoretical model

to summarize: the x and y values represent the respective front and rear axle stiffness... the z values is a ratio between them based on load transfer.

In short the stiffness of the axle also determines the stress punt on the tyres.

If there is any way to calculate the (sheer)force/strength/stress absorption capacity of an axle... please let me know!!!

I do know how it's determined...
push-and-pull methods...
Like previously mentioned --> really unsatisfying


PS: I've guessed about the height of the CoG, and put it at 0.5 m

RDM... nice, Hogeschool Rotterdam massive (I work there at the HRS - BIT department, only I'm located at the Westblaak).

Doing automotive studies @RDM?

On topic: looking forward to your rebuild

[CA86]

@ Cavey: Yes, my main activity is Automotive Engineering...
BIT department? I don't follow.
with HRS you mean HR Services?

tomorrow I'm going to contact a local store which sells/deals in gas bottles for welding purposes...

and there is a high probability I'll be starting the rebuild in the next two weeks... If nothing serious happens to undermine which has been stated above
