RUH´s trackday E21

[ruh]

Cheers guys.

Here´s my tracktoy. Long story short, i saved it 5 years ago where it was sitting and rotting in a driveway. Bought it and fixed an absolutely idiotic amount of rust. The plan was to have it on the street, and it was for a short while. However after sitting still for maybe 10 years in a driveway the original M20 carburettor engine just caved in. I was kindof at a crossroads, but decided to modify it. The car was so far gone that it would never be an original showwinner again. So why not have some fun instead. So i installed a M20B25 with fuel injection etc and those 160bhp is really what this car should have had from the start. My god it goes like stink. And not in a crazy insane way (its still only 160bhp) but in a cool sofisticated way. Smooth, but angry

Anyways, that became the start for a trackday car E21.

The bavaria edition has a metal sliding sunroof, a big blaupunkt radio with synthesizer, one electrically adjustable side mirror, and green tinted windows.

Nice work on getting this car back into action! Some serious work on upgrades making it ready for trackdays which are great fun of course. I'd install a full cage first though, any plans for that?

Hi Jeroen. Yes a full roll cage is on the design board. Trackdays here are not like they are elsewhere, its really just "open track" and alot of guys come with their completely stock normal streetcars and do some laps. So a rollcage is not required, only thing required is a crash helmet. On the other end of the scale tubular chassis homemade cars are not alowed either.

I am planning to weld the roll cage this summer

Over here it depends on the organization and the track as well, a lot is allowed but since the E21 chassis is not that tough, a cage is advised

Yeah the regulations are very different from country to country. The E21 chassis is very soft, if you jack it up the doors wont close

I am planning to do a weld in cage, that will be implementet to the cars chassis on a, b and c pillars. Also the rollcage will be attached to the front strut towers.
