Spaceframed SR20DET RWD Nova

[The Simps]

So to update...

I’ll let the pics do the talking but basically:

1) I finished all the framing on the tubing on the rear end bar a few finishing touches and an x brace on the large centre piece. I’ve not bothered to make any more panels out of steel at this stage, knowing/hoping it will all be carbon anyway.

2) Remove the outer sill on passenger side.

3) Refitted engine & box.

4) Started to think where my new floor needs to be, especially around drivers feet with wheel clearance and gaining whatever space I can! I might drop down a tyre size I think, just to give me a little more room.

5) Build a dolly jig so I know the new floor will be level to all the main pickups. Principle is 70mm box on same size wheels as rotisserie, so the two go together and also separate - is modular the right word? I then cut loads of smaller 70mm cubes that I can stack for consistent height. Front subframe is to be the lowest point and also the floor level so I can then go flat right the way through. Subframe is 3 cubes high off the jig (210mm). Once floor is built there is a very high chance I will be redoing the front chassis legs/subframe pickup points, probably out of tube. Floor will be made out of the 25x50mm box.

6) Attach car to jig













It’s been so much thinking, staring, head scratching and pondering to figure out how best to move forward, but mounted everything squarely to the jig tonight and see my cubes actually work was a real feeling of achievement and progress.

Now to plan removal of the old and in with the new!

p.s. ignore the rotisserie at the rear and its support through the middle of the car, they are turned to one side, so not running down the cars centre at present!

So quiet week this week but got 3hrs in this afternoon.

After lots of checking and re-checking that everything was stable and won’t collapse on me, I made a start at removing the remaining sills and floor sections...






You can now see with the sleeved extensions where the new floor ends up.





Need to scollop the sleeves around the horizontal tubes for a better fit and to have more of the pillar posts inside the sleeve. Will also make 1 or 2 uprights and a diagonal piece at the rear. Like this...




The front will also tie into the front subframe area but will do that when I come to redoing the front chassis rails etc.

Hopefully will get some time for progress evenings this week

Being a financial adviser, this week was not exactly quiet at work so no Neva project time. But put in a shift this afternoon and got the drivers side sill/floor and supports made and reading for tacking.

Thanks fellas.

Being stuck at home I’ve put some good time in this week and nearly finished the main part of the floor structure, removing all of the old...





Should have the front part of the X welded up today. The floor is 25x50 box and there will be additional supporting 25x25 box where required, such as around tunnel. Pedal box area will obviously have a well supported structure too.

I will then need to add a small trapezium shape section that will run between the rack and bellhousing like so...



Then its engine & box back out to start thinking about the redesign of the front end, particular the chassis legs.

Really enjoying being back on this
