I wasn't happy with the location of the brake master cylinder, it was exposed and could/would be easily damaged in any front end contact, and I would need to make some sort of protection around it, = more weight. I managed to relocate it inside the frame just in front of the brake pedal, a...

I've used the wing mirrors from the micra mounted on an aluminum angle rivetted to the side panel, they can fold in also. They're very effective and for now I don't mind the (mickey mouse) look of them.

Johnny also welded the air box connection, its a piece of 70 x 35 aluminum box with a short piece of pipe for the air filter to attach to. The other end is drilled to fit over the inlet horn of the SU carb with the threaded bar of the inlet horn going through the top and a 6mm nut holding...

The fuel tank is made form 2mm aluminum with a cap I got from Demon Tweaks, my mate Johnny welded it for me, he's really good. There's a swirl pot underneath with an 8mm pipe connection It's fitted behind the seat with the exhaust behind it, I'll wrap the exhaust and put a heat baffle covering...

I asked a local kitchen counter top company if they would measure for the panels using a Proliner 3d measuring machine. They gave me a folder with a .dwg drawing for each panel. I got these laser cut from 2mm aluminum. They mostly fitted well, I just needed to grind away a little at the...

Using the stock micra front suspension struts would mean the ride would be very hard (Micra 820kg midget car 340ish kg) and sitting at the top of the struts travel range with no drop available. I die grinded away the weld of the lower spring seat to allow it to drop down the strut completely...

Rear suspension. The box section lower part of the rollbar has a tube welded in place. This has a push fit polyacetal bush inserted and the front round part of the lower control arm fits in to it. This is the RHS, note the sump alterations (hammered in) to make room for the lower control arm.

The engine has to be naturally aspirated with a max choke size of 1 & 1/4". I sourced an SU carburetor from a1970's mini 850cc and made an adaptor made from a 32mm but weld 90° bend and 6mm flat plate connected to the inlet manifold where the throttle body was, the bend is cut to the angle so...

The regulations say you can alter the exhaust back as far as the first bolt on item to the exhaust manifold, so I cut the top section of the catalytic convertor and welded (with cast rods I got on ebay) a plate that the first section of a new 2" exhaust is welded to. I used 2 30° and 2 60°...

The distributer had to be altered to be mechanical electronic ignition with a coil which means I wont need to use the ECU, have any issues with the immobilizer and a lot less wiring. I sent it to H&H Ignition Solutions in the UK who sent back this with fitting instructions and a new coil...

Next up, final assembly, engine cooling, carburetor fitting, suspension, flooring, pedals, steering........ The Micra thermostat housing was pointing forward to where the rad used to be but also into the seat location so I replaced it with an adaptor I had turned to connect the pipe going to...

Hi Cat, Just letting you know to be cautious of MachineAddict I think he is a scammer and I see he has responded to your oil pump search, last week NitroWade coned me by selling me camshafts he didn't have, he just gets pictures and info from other ads online and once the money is sent it all...

Welding. My brother in-law is a fitter with the power company and a very good tig welder, he acquired some high quality rods and he got the whole thing done in one long day, thanks Jim. Then it was, grinding, sanding degreasing and washing with acetone to get it ready for heat treatment and...

Body work. The plan is to infill the frame with panels of aluminum so most of the frame is visible, I got a local engineering co. to laser cut 126 tabs from 2mm sheet and I made a simple jig to position them so that the outside face of the aluminum will be on line with the center of the frame...

With the frame almost complete but still only tack welded it was time to strip it down for tig welding, cleaning, heat treatment and painting. I'll just sit in it for another size check (cue inner child complete with engine noises) To make welding a little easier I made a simple rotisserie from...

Yes, the pump and controller are variable speed and it controls the fan also so it should be good. The midget race car regulations are all about keeping costs down and competition tight, the engine has to be from a 1L or less road car and has to be naturally aspirated with a max venturi or choke...

Hi FHM, thanks for the info, great to know others have used the mini cooper rad (and that there's more than 1275 looking at this😃). I've removed the water pump (for a variety of reasons) and I'm planing on using an electric Davies Craig EWP80 Alloy Electric Water Pump & Digital Controller Combo...

The gearbox gear linkage is welded to a box section welded to a universal joint welded to tube welded to another UJ connected to a piece of solid 10mm going through a 10mm tube welded through the bottom rail of the roll hoop connected to a 3rd UJ welded to the tube connected to the Micra gear...

The seat rails are 80 x 40 box section cut to make 2 angles, these along with brackets on the lower frame rails are 2 more harness anchor points. I got my machine shop up the road to make 2 bespoke washers to fit the holes in the Kirkey seat. A countersunk cap head bolt spot welded into the...
