Locost based middy, plan to use subaru ej20 engine
Hi everyone, greetings from down below  , South Africa, Cape Town. I love what you guys and gals are doing.
This is my first time posting on this forum, I've been reading all the middy posts for a while now. I chose this project for my final year of
study in industrial design. I know this is crazy, the car must be done in 4 1/2 months. I have designed most of the chassis and I've come up
with a design for the body already.
I am looking for the dimensions of the EJ20, Subaru engine, and I was wondering which gearbox I can use as a 2wd box. I saw a post on welding up the
internals of the 4wd box for RWD but not sure if it will work for front wheel drive.
Has anyone else done a scooby based middy succesfully?
Heres my concept design, my chassis design is on my other PC, I'll post it tomorrow:

Why not use the 2wd gearbox as its slightly shorter than the 4wd one
ho idea as to dimensions use to work on them but never measured one

Welcome.
Only Scooby based middy I've come across is the "Saker GT" http://www.saker.co.nz/ though I don't know which exact engine it
uses.
On your project 4.5 months is very aggressive to get a body made as well as the mechanicals. See "Fred W B" "Gaz 1977" and
"sgraber" posts which should help a lot as a start. On the positive side it isn't the most complex shape (in a good way - I quite
like it from that angle) which makes life a lot easier. Do you have lights in mind or will you be fabricating/faking some?
There is a Subaru 2wd gearbox but it's not as common obviously.

Some of this was discussed quite recently here but are you sure about a front
wheel drive middy?

Thanks for the swift replies guys.
zzr1100rick2 and iank Contributor
: I heard bout a 2wd box but I'm not sure if it will fit.
I planned to make the body out of hemp and a plant based epoxy resin.
RazMan Contributor: That post dont have any dimensions

OOOOOH, i just went through the "Subaru Powered Midy/Thoughts?" post and saw that the gearboxes look exactly the same except for the end
section that probably houses the centre diff.
Its not a FWD middy, its the subaru drivetrain's front section without the prop

You eco-warrior you  no idea about that as a material, but the I guess you still need a negative mould, so therefore a buck i.e. a full size car
body made of wood/chickenwire/polystyrene/plaster - or whatever will be needed to model the final shape and pull the moulds from. It's that bit
that takes the time if you want/need a quality final body.

"eco warrior", good1
Its basically the same process as making a glass-fibre body, I'm just using hemp fibres instead. This is why the body is so simple, its divided
into a front,back and two sides. The car is planned to be more then 95% recyclable and/or ground into biodegradeable grains/dust.
Quite optimistic, I know. but I'm sure its a good learning curve

If you want the dimensions of a Subie motor there are several importers of used motors in Cape Town who normally have Subie motors in stock and who
would be happy to let you measure one up.

Thanks for the suggestion, fellow South African I'll go around tomorrow morning

Here's a few pics of my chassis, some constructive criticism will be much appreciated:

I'm no expert, but I am sure that you will need a LOT more triangulation in that design.

You can do it quickly. You can do it cheap. You can do it right. – Pick any two.

better chassis
OK,
The tunnel is probably doing nothing for the chassis, in fact the whole chassis isn't going to do much for the chassis until you put in some more
triangulation!
A front like the one on this would be a lot better. The blue lines show the bigger 4x2 14 gauge tubes around the engine bay. A spaceframe rear is
certainaly possible.

Thanks for the advice guys , I was going to add a few cross members into the design, but its still a "work in process" project. I have
another idea that could probably work much better with less tubing. I'll get cracking and post something later.
