940 & 960 960 Rally Car
Starting this thread early for a couple of reasons - the main ones are to use it as a planning thread and to see how close the finished reality is to the plans...
Having not quite finished the BMW, I shouldn’t be starting a new project yet, but there’s a few things motivating me to do so:
First is a couple of good mates had a BIG crash at the Alpine rally late last year, and one of them suffered life threatening and life changing injuries. The short version is that a bunch of weird events put them into the scenery at full noise and were unlucky enough that they hit a “perfectly” sized tree in the gap between the chassis rail and the engine block, negating most of the crumple zones built into their 1970s Japanese car.
This has lead me to wanting a more substantial car and (particularly) more substantial rollcage. Specifically, I want a bar between the front legs and bars out to the strut towers.
The second main reason is that I have been watching too much Swedish Rally on YouTube (https://m.youtube.com/user/SwedishRally). This video has been notably unhelpful:
Here’s a screenshot from the video...
Combined with the ever-present need to build or fix something (aka my mental health plan) and having some cash sitting around, meant that I went from “idly kicking an idea around” to committing to the project.
After some discussion and much hand-wringing, I decided to start with a live-axle 940 bodyshell, rather than one of the IRS 960 shells.
I have two white 940s in stock (ie: sitting in the back yard). The obvious choice was the 91 GL because it is the rougher car and doesn’t run.
And also because it has manual windows.
Here’s the plan:
- 91 940 bodyshell.
- B6304 motor.
- BMW 6-speed gearbox bia adaptor plate (KL Racing or DIY).
- Toyota HiLux diff, 4.55 ratio. LSD if I can find a cheap one, locker otherwise.
- Hotbits front struts, with MCA valving.
- Offroad Bilstein rear shocks, with MCA valving.
- Two sets of Triumph triple throttle bodies.
- Autronic SM4 ECU.
- Proper bias adjustable pedal box.
- Comprehensive weld- in rollcage.
- Falcon 15x7 Snowflake wheels.
- Plus all the usual rally gear.
I have already accumulated most of this stuff - the main bits I don’t have are the rollcage, rear shocks and ECU.
While my shitty gall bladder and consequent health issues has been limiting my ability to actually get on and do things, I have been buying stuff!
