@@idontwantachannel3091 wow, must have been quick with the rotary ! I understand how much work would have gone into it. Nice.👍

Thank you for your comments ! I used a Fiat 124 tail-shaft (propshaft) centre uni joint which is splined, and had a thicker axleshaft made in 4140 material. The uni joint is then secured to the new shaft with a locknut, the same way it’s attached to the original tailshaft. This was then adapted to a machined Fiat Regata 100 s front hub, which has the same spline to suit the original 850 short shaft. Some machining and drilling needed to make it all work together. It’s been reliable and more than up to the job. Good luck with your project.

@@Tony-pr7te Thank you very much! Now to accomplish it, which will be fun :) A Fiat Regata 100 was not sold in the US so that will be an interesting find on the internet.You make things sound kinda simple, but I know the research and time spent on making things work has been a challenge. Having sheared off about 3 rear axles and shattering 4 sets of spider gears the gear box has been my weakest link. No issues with the engine, runs like a champ!

@@againstthetimes Yep, you are right. Lots of head scratching and experimenting getting there ! Very satisfying when it all comes together though. After doing some laps at Sandown race track I discovered a way too big a drop from 3rd to 4th, so a 5 speed or taller 3rd would better suit my car. I don’t normally track day the car so I’m just going to live with it for now. Good luck with it all !

@@Tony-pr7te I have a close ratio 3rd and 4th gear, straight cut weber gears on my gearbox. It defiantly has gear whine. My 4th gear is one to one, no overdrive that the stock gearbox has. With 22 inch tall slicks, whatever my rpm was was my top speed. I have run 5/57 rear end, 77 mph at 7700 rpm roughly, with the 4/11 I hit around 108 mph at 8000. The 5/57 rear end was about 5 seconds 0-60 mph, great for hillclimbs that were steep, not so great for shallow ones. This with my 124 twin cam engine. My 850 motor had 940cc and needed the 5/57 rear end. My 850 spider still has the record at the Hoopa Hillclimb in the states with that combo in H prod class. The hill climb is no longer unfortunately. You can get close ratio 3rd and 4th gears that have to be welded on and the layshaft gears in Europe, forgot who had them, they will not whine as they are not straight cut. All the 5 speed gearboxes are no longer as I have been looking for one for years.

Thanks Jerome !. There is a big list of mods, however, the main ones on this 1969 850 Sport Coupe are the modified Abarth 1049 cc motor, rear disc brakes, driveshafts with outer uni joints, modified and lowered suspension, and a redesigned front end to cater for the front mounted radiator, with a deliberate nod to the OT 2000 Coupe series 1 from the mid 1960’s.👍

@Tony-pr7te thanks for your reply Tony. I'm considering buying a 69 Coupe here in South Africa. Yours is inspirational.

@@jeromemausling6324 Look up my channel Jerome, there is more footage of the 850 for your interest. Good luck with the project !.

Thank you. 🙏

Hi John, thank you for your message. The 850 (1049cc) is great fun to drive, and so far, reliable !. I also have a 2011 Abarth 500 SS as my everyday car, and have a permanent smile when driving it…👍

Thank you ! It’s a modified Abarth ‘A112 A2’ 1049cc motor with a copy of a Group 2 TCR exhaust system. 👍

Thanks Alastair ! 👍

Thanks for your comments John, much appreciated.

Hi Nelson, I’m using Bridgestone Potenza’s re003. I’ve also gone to a 205/55/15 in place of the original 195’s, happy with the grip and hoping the wear rate is going to be good.

Im running the re003 on my protégé too, same size and everything, its an awesome set of rubber @@Tony-pr7te

Next track day in September I’ll play around with tyre pressures for some fine tuning, although the balance feels pretty good so far for Sandown. 👍

37.9 in the dry and a 50.9 in the wet. Hoping I can get closer to that 1:35.00 next time out with more laps and a few tweaks ! Looks like you had fun in Rhonda 👍

Cheers mate 👍. Got a few dry laps in !

Thank you. I had a professional do the metalwork at the front with my templates and had the body painted by a friend. The machining for the motor and the head work was done by a local engine shop and the seats re trimmed locally, I did everything else. 👍

Many thanks mate 👍 I look forward to seeing you at the track again soon.

Unfortunately our one and only GoPro battery died not long after the first session, so no footage. The car held up really well, main impact on the left hand A pillar and the roof was badly buckled. The driver was fine though and happy that we had a race seat and harness fitted. That’s why I fitted a cage to the Camry…

Hi Enden, I use an electric water pump mounted at the front of the car.

Hi Risson. Happy to answer any questions that might help.👍

@@Tony-pr7te may i ask for a video on your engine bay. please。

@@Tony-pr7te engine bay video pls haha =P

Hi Risson, I’ll upload some footage in the near future.👍

@@Tony-pr7te may i know what water pump you use? please

Thank you 👍

Thank you Mick.👍

Thank you for your comment Andrea. The motor is is an Abarth a112 a2 1049 cc. 👍

Thank you for your comments Harvey. You are right about the bonnet buckle, however, I do have a sneaky strip of clear ‘helicopter tape’ on the bonnet to prevent scratching from the strap. 👍

Hi Liam, thank you. The black box is a main fuse and relay box, which is part of a complete modern wiring loom brought through eBay, modified and adapted to fit in an easy to access spot.

Thanks Alastair. This car started life as an 850, it’s neither a Cooper or an S , I just wanted to build my own interpretation of a quick mini using a mixed bag of parts ( including badges…)to achieve my goals. So much fun to drive !. 👍

I believe the 2nd tank was an option. Info on the differences are contradicting, I believe the Cooper and Cooper S are near identical. The S might have better disc brakes than the Cooper. The S, being a later car, maybe has bigger capacity engine. But I'm not sure. The S badge is usually associated with a rally homologation type of a car.
