2 quick questions

1. in the book it says to use a 16swg steel sheet for the floor, but would 1mm be enough?

2. will i have to make any modifications to the transmission tunnel to fit a t9 gearbox?

1. probably

2. probably not.


short answers?


basically, the floor just stops your bum hitting the ground and stops things hitting you. its not structural. i would recommend that you put an extra one or two rhs members across the car under where you bolt the seat or the floor will move around and 'ping' a lot.

Alu is about 1/3 weight of steel. why not use alu if you are trying to save weight on the floor?


the tranny tunnel is relatively wide in the book, compaed to the prop shaft dia. However i made my car 6 is wider so my impression of room may not be the same as yours. You are most likely to have to increase the width of the opening at the bellhousing end of the aperture. however, you might compromise, if you have room, by moving the engine forward. on my car it was the clutch release arm that was a pain.

In the book its says you should use 16g for the floor or use the roof panel from the (Escort Mk2) donor. The roof on the essy is only 20g (0.9mm) so I dont suppose it matters?

that's what i was wondering, because all the roofs i've seen so far seemed to be about 1mm, so i thought that the old escort may have had a thicker roof.

I expect that in the book 16swg was suggested because it is easily obtainable, not because it is the minimum thickness suitable

I have got 2 sheets of 16swg steel and I don't think I'll be using it, it's way too thick in my opinion, I'm sure I can make use of it on some other project.

I used 20swg sheet steel. It's OK but I had to fit a couple of additional cross members afterwards as when you stepped into the car the floor wobbled and distorted. OK now. For weight reasons I wouldn't have used 16swg.

you found the same as i did. I used 16 swg and you still get the wobble.

Use a couple of extra supports for the seat and the floor can be virtually anything. However, there was a nasty report on TOL once of an aussie getting something sharp up through an alu floor once. Dont suppose there are too many spiky things on english roads thou.
