Medium I would say. The engine loom is fairly well self contained, immobiliser is not that complicated. ECU Needs a speed input from the transmission via the instruments which you can do with a Dakota sgi-5e and a feed from an ABS ring or elsewhere. Clutch and N sensor.  Battery is mounted in the back end so lots of wire. I had to extend quite a bit to re-use the gauges. and I had already used the column switches for lights so just built a bit of circuitry.  Bonus is that wiring diagrams are available. Mine was a Mk 2.5 from 03

I undid all the unneeded pins from the connector blocks rather than cut wires

To Start


Spare bits


Packed


Made up bit





nice neat work there sparks

got any links to mx5 wiring diagrams ?

Thanks  - the key is to put it in a box 3x the size you think you will need - just about fits then ;D

It was a Mk 2.5 from 03

I got some 2.5 diagrams from elsewhere but can't remember - I have 2 versions - if you end up with one I'll ping it over.

I lived in the US for a couple of years, FL (hmm)  and WA (yay!) spent 6 months in Alaska/BC as well (awesome!)

read through this


https://grassrootsmotorsports.com/forum/grm/using-a-fwd-drivetrain-for-a-mid-engine-awd-setup/91900/page1/

I have read through this but don't understand why they suggest a reverse cut gear set would be a good idea

"this is an excellent idea. I propose we toast, and then get started right away.
I guess one problem would be that many front axles have an offset front diff, because the engine is usually in the way, but maybe you can get away with that with CVs on both ends of the front driveshaft.
Do any serious rock crawling people make reverse cut rear diff gearsets? if so, getting another IRS rear diff on the front but using FWD CVs, Spindles, brakes, steering gear, etc might work."


I can take a diff out of the back of a range rover and put it in the front its still the same item why would you want it reverse cut ?

well my only thought when i read that was......a front wheel drive cars axles turn counter clockwise in forward gears. i assume that most rear wheel drive drive shaft turn  clockwise .I assumed that was it,  but i also think one could simply roll the diff  over imo.

Getting back to my "Road Rail design", I did some sketches based on a print out of the LWB Vittara chassis, sort of part trophy truck, part sand rail, part bouncer. Unfortunately I suck at design or drawing but I sketched this>



Then today  on one of my google trawls I found this uncannily similar  awesome looking thing



https://www.wideopendesign.com/evolution-rock-crawler-chassis

Now I don't like the Jeep grill just the flat hood but I just love the layout and form  - obviously it's not designed to mount on a chassis but that shape of a low-ish slung cockpit between the wheels look great.

There is a sketch of the frame somewhere so time to get to CAD, wood sticks and duck tape

your drawing looks like its on a print out of a lwb sj chassis not Vitara  leaf springs and weak  solid axles

this is where I am going with my Vitara chassis,   big V8 up front and a tube frame that bolts onto the 8 body mounting points

Yep I think you are right it is the Samurai Chassis drawing - all I could find.
 


Wheelbase is 10cm different I think. Do you have a LWB Vitara drawing by any chance?

search using escudo or sidekick there seems to be more results for those names than vitara

no shit!  Carry on!!

Thanks. Have you got a link to that file please - postimage shrinks it and makes it low quality.

I think I just googled  sidekick chassis dimensions  which threw this up

https://bbs.zuwharrie.com/content?topic=110158.0

then I just copied the chassis image half way down the page
