Plug and play, I have swapped them between stages in a matter of a few minutes.

Time is hard to tell, I would base it on mileage and how hard it is driven. An average rally mileage will be less than 50miles but those miles are nearly all flat out. Other other competition car is a more standard MGZR160, as it is a standard engine it gets less oil changes and I base the...

I have always used 5w40 Fully synth oil, various brands what ever I can get cheapest. But very regular oil changes, so for the Micra the oil & filter gets changed after every event.

Never had an issue with the MOT, but ours is a full stage rally car, so there are allowances for rally cars and MOTs. Can't see most MOT testers having an issue with it.

Removed the cams from the CG3A engine I bought just before lockdown (everyone was panic buying bog roll, I was panic buying engines ;) ) Turns out it is very nice inside, the cleanest I have ever seen a stock CG3A engine, no sludge at all. Not been apart before, clearly only done low miles and...

Check fuel pump relay, blue and down by your right foot when driving. They do fail, caused us some issues in the past, pump is now directly powered via a switch.

Roof felt I found you either end up with not enough (as you found) or way too much which you then store, and then find it is useless when you next need some... What flashing tape did you use? I need to re-felt our shed (tyre store) over the summer.

Would one work for the dizzy cars?

Every turbo thread on a CG engine when they blow, they blow no. 3....

It's always no. 3 that lets go, I suspect the water ways around the engine means it runs hotter than the other 3. They all end up using oil after lots of abuse, my old rally engine always drank oil....

Actually nothing to the Micra for months as it is all ready to a British Championship Rally back in April which of course never happened... So here is an old pic of the Micra rallying on #WheelsUpWednesday So been working hard on the ZR... Fully seam welded both front sub-frames, including...

Let me know how well this works, I tried modifying the OEM cap and it leaked all the air out sadly,...

I think your revised design is fine. Remember the OEM cup is barely spot welded into place.

Yep all sorted now, also found one of the inlet manifold nuts missing !!

Read Paul / Polly’s blog everything you need to know about turbos is in there!

Always the way, found a large crack in a front chassis leg on the ZR today whilst doing other jobs...

Seems ow, I would like to be seeing 150psi+ this could explain your oil consumption....

It's useful painting suspension in a lighter colour, I spray all mine in silver. It brightens things up under the car when working on it, and makes it easier to spot cracks. I found one once like this on the rear beam, doubt I would have seen it if had been painted black.

I have been running my welder for 10+ years on a standard 13a plug, it should really have a 16a plug on it. Only caused an issue once when I was playing with it running flat out, and it blew the 13a fuse. Swapped for a normal fuse and away again. Unless you are planning on lots of flat out...

They all lean a bit towards the passenger side, I am told it helps with oil surge. Check engine mounts and the gear selectors.
