What gearbox are you going to use and where are you getting the adaptor from? Or is it going in the back?

judging by how short the front is id say rear engine at a guess

Looks like a transverse engine and gearbox to me, (I expect from a FWD car) being fitted in a mid engined configuration
As some day it may happen that a victim must be found,
I've got a little list-- I've got a little list
Of society offenders who might well be underground,
And who never would be missed-- who never would be missed!

If you look at the size of the centre tunnel, it isnt big enough for a gearbox/prop. It is a FWD engine, presume from a fiat coupe turbo? going into
the rear of the car

Dear god, I hope you are going to fit wheelie bars to the back of it! The 20VT engine must weigh nearly as much as some entire Locosts!

Is it me or is that made from WOOD ???
Looks a bit flimsy I'm
Afraid don't think them
Suspension mounts will hold !!!

I'd have to agree, the front suspension brackets don't look overly robust to me.

especially the ones on the drivers side, they are hardly visible ;-)
Looks nice to me (no idea on bracket strength), what bodywork are you going to use?

fair play on building your own chasis takes alot of pattience but how comes its made from wood ???????????

Its not wood? Since when do you weld wood together? lol
Look at the pictures from the front, you can see the welding.
Kindest Regards,
Richard.

£50 on it that it's made of wood
You can see nail holes. and the roll bar is bowing with the weight of the masking tape (look closely )
Also there is a pile of wood next to it on the floor lol and it's painted in gloss White lol defo wood
Must be a Mock up chasis ???

Look at the second pic you can see bare wood making the rear frame ..
This is by no means me being disrespectful to the owner he's doing s top job on the mock up and nice to see something diffrent

Not knowing a thing about welding but maybe he's mocking the whole thing in wood to make sure enough space etc then label each piece and use as
a template? similar to the Haynes locost book but in 3D rather then plans?
Lot of patience gone into that.

i cant understand why people still insist on using a chassis design originally intended for a front engine car (a bad design at that) and stick the
engine in the back??
all you end up with is an over engineered front with an engine hanging off the back.

Hi All,
Thanks for you comments, appreciate them. Good and bad.
Yes, this is a mock up, building it in wood to refine my design, I started designing it about 10months ago, and at that point did not have an engine!
I will be using the Fiats original 5 speed box with LSD – may upgrade to a 6 speed later if required….
The mock up is basically to help me try components out and then I will amend my CAD drawings to suit. The reason it looks like it has welds is I used
a hot glue gun to stick the bits in place, then screwed it together, hence the holes….
I think its better to take your time and design something fully before jumping in and making a mess. I have no other needs for my garage so it’s
perfect for taking my time and doing a good job on it. At this time of year it’s really too cold in there any way so it’s better to be on the laptop
in CAD. 
The front suspension mounts are fibre glass I knocked up to help design the front suspension.
The comment about using an old design…… Sorry to disagree with you on that one, but this is my first car and I have always loved the
Caterham-Westfield style car. I want to keep the design looking as similar to that as possible but adding the new twist of a more modern, more
powerful engine. And I love turbo’s, the 20v five cylinder fiat engine does sound sweet. Appreciate it is not the lightest engine, I will be working
on that, don’t worry.
Body work wise, its going to have traditional side panels, but made in carbon fibre rather than aluminium.  The rest of the body work will
be similar to that of a normal locost.
Actually, what you see in the mock up (wood chassis) has only cost me about £35 in total, this I feel is money well spent as I have made some major
changes to it over the last few months which would have cost a fortune if it were the steel finished chassis!
Cheers Rob

Certainly does, it's a wonderful sounding engine.

I almost gave myself a hernia lifting the cylinder head back onto the block when I fixed the melted piston in mine - and that's the alloy part
of the engine  Still, it will make a ridiculously quick car if you can sort out weight distribution etc.

Thanks Mike,
Will let you know what she sounds like in about a years time when its all built into the chassis!
Have you got any tips on bits i dont need on the engine?
I am going to bin the powersteering pump for starters and i think some of the hoses could be replaced. Won't be using the subframe so can get
rid of some of the gearbox mount which bolts on the box.
Cheers, Rob

If you make the carbon fibre panels stiff enough, you could bond them onto the chassis, not just rivet or screw. The potential for them to really
stiffen the chassis is quite enormous. A guy that I know who has been developing is open wheel hillclimb car for about thirty years recently added
stressed skins to his chassis and after all this time he can now progress with his suspension. For years, the chassis has been so flexible (in twist)
that no amount of suspension twiddling was having any real effect. The chassis flex was part of the suspension effectively. With the skins on, the
chassis rigidity has gone up in orders of magnitude. He used a honeycomb panel with carbon skins on his car.

Nomex probabily. I used to be a boat builder and my current job involves a lot of composites.....
Yes, I know exactly what you are saying and I am looking at stiffening up my car with the panels as I want to reduce weight, that 20v is heavy!
Looking at a target weight of about 550kg.....

Hi all,
I have began tidying up my garage for boarding out. Once that's done I am going to start building my table.
I have put the engine in the frame now so I can develop the rear suspension. I got a mk 2 escort steering rack from one of our locost members, thanks
Steve! So that's showing in photo too.

I will post some photos of the rear end later, interestingly, as some might guess with that 5 cylinder turbo in the rear of the car there is not a lot
of space.....
Part of the rear frame is going to be bolted in once the engine is in place. Will be making all new engine mounts. Anyone else bolted in part of the
rear frame??

Sorry I missed this post. Are you intending to run the original ECU and immobiliser etc? You might be able to dispense with the massive alloy
casting that holds the PS and aircon pumps, or at least cut it down considerably. You can also get tubular steel exhaust manifolds to replace the
heavy cast iron lump which will either be cracked already, or will crack at some stage.
