Allo chaps & gals, first time posting here. (Also made a post on passionford)
I post most of my stuff to a build thread on fiesta-mk1.co.uk, thought I'd share it here. Hi sam.
1978 Mk1 Fiesta Model 950cc 45HP project, swapping in an ST170 with a Escort Mk5 TD / Orion 5 Speed MTX75 gearbox. Will be driven daily. Acquired the car in mid 2019 and drove it for a few months, then my brother put ideas of a Zetec turbo in my head & it wasn't long before I picked up a complete St170 + 6 speed getrag box for £200. First thing we did after getting the car was swap the front suspension out for modified corsa coilovers, quick hit up with the die grinder got them on and modified the top mounts to suit. See pictures.
Started doing my homework on how to approach it all & finally found the gearbox I wanted at the end of 2019. Rebuilt the engine over the last winter and earlier in 2020 I pulled the Valencia engine out to size up the St170. Cut the chassis rails on both sides and reinforced them with 3mm steel plate, made my own mounts with the help of my brother and father. The rubbers for the mounts are from the leaf spring setup on the back of a transit so they are plenty man enough. This was after I modified a existing CVH mount but just didn't like it in the end. Bought brand new Focus driveshafts for use with the gearbox, the half shaft is now mounted on a modified Focus mk2 bracket. Runs true. Making the exhaust manifold right now with the inlet manifold partially cut out of 45mm ally tubing, just needs tigin' together.
Next big hurdle is turning the driveshafts on the new lathe I recently setup, I've got a plan for it. After that its just the usual manifolds, breaks etc.
Engine Management: Motorsport Electronics ME100 / Speeduino. Both will be on a common loom so I can run the ME100 until I've finished writing the cam sensor decoded to run the VVT correctly in the speeduino firmware.
All of the work installing, making/designing, painting is done by myself, my brother & my father. We don't have access to any fancy water/plasma cutters or CNC mills, so my brackets may look a bit rough and ready but when the time comes I'll draw them up and order some proper looking kit to tig up when the time comes to paint the car next year.
