Small Correction: It is a 1965 not a 1964.
It was PRODUCED in 1964.
Hi, hope the original paint is kept by the owner. Anything else would be a sacrilege.
BTW: The anti-roll-bar is from Speedwell
tHanks again....Because of your video...I went and organized my first playlist.
Now my Mini videos are together....unlike my Minis.
@@TheRedMoron I thought I reognized that but I just couldn`t put my finger on it.
Slot drive oil pump.. damm thats already when you know even those rocker arms.. nothing like some AEG parts !! Nice to see an old school Classic Mini DIY back on the road !
You arent kidding! This engine was full of some really cool bits. Hoping to reuse as much as I can.
So cool. The original owner was an absolute rock star. Drag racing, ice racing, what more could you ask. My folks and the owner and her hubby were friends since elementary school. The dad's had quite the pedigree from sneaking away from home to attend F1 racing at Watkins Glen on the old road course to club racing, camping at the races and all that. They were big fans of the little British sports cars for sure.
Thanks for viewing the channel. My mom and dad where big in to racing. My dad always said that she was a better driver. I hope to have the car finished this year. And a big thanks to Cole and Classic Mini DIY.
@@ahartsclassicminigarage8833 you are the owner of this great little car? I would love to see the car when it's done.
@@franskamstra2728 yes I own the car it was my mothers car
@@ahartsclassicminigarage8833 I don't know if you have seen the question I asked classic mini diy. But do you have any performance figures of how it was back in the day your mother showed all others the dust. And do you have a goal of how it should be when its done?
@@franskamstra2728 I don't have any figures of the performance back in the day I do know it had 13/1 compression. My intent is to bring it back to as original as possible. Just undecided if I should have the body taken down to bear metal and repainted or leave it alone with the patina
Hi Cole, apologies, a bit slow getting on to this. You are correct about the rear anti-roll bar, it is a period Speedwell model for hydrolastic minis. They made a similar one for dry suspension, with different outer attachments. Fantastic project, looking forward to more. Cheers
That bracket on the timing cover is from an Austin 1100 😊👍🏾
Looking forward to hearing more of this car/engine. My Morris Cooper S rolled of the production line Dec. 17th '64, delivered to South Oz in Jan '65. Same colours too. Rebuild in progress.
The anti roll bar is a speedwell.
Awesome cooper s, looking forward to watching the rebuild. These vids keep my enthusiasm up as I restore my '68 Mk1. Thanks
Me too!! From South Africa.
Awesome history on that car! Definitely see if you can get some old pictures of the car in its prime to show us
Thats a great idea. I'll text the owner!
Hi Cole, nice job with this video and looking forward to following this series. You asked if any small things that viewers noticed could be pointed out. I think I saw the EN40B marking on the crank web, which would mean it is one of the best ones, and possibly is cross-drilled. Post the markings here and I can tell you more. One thing to point out also is that the Cooper S blocks had removable tappet covers on the back like small bore Minis and unlike the solid-back 1300 or later A+ series. Also, the head has 10 studs and one bolt instead of the 9 studs of the other Mini engines. Hope these are useful.
A family friend took me for a country lanes blast in one of these 30 years ago....I've wanted one ever since..... his is a mk1 Austin Cooper s 1275 too, a grey one.
I have an almond green Australian 65 deluxe which is my first car original 44k miles only a 998 . Purchased the car back in 1990 waiting now for a rebuild I love the colour my first love 😂
Looking forward to seeing the build. Love the history of the S. Beautiful car. He chose the right guy for the job.
This reminds me of my 67 Austin Cooper
Sore one of these mk1's go through a auction house for £1800 and it was not in as good a shape as this one and the buyer said it would possibly cost as much again to rebuild , keep up the good work ,I have mini's to repair , thanks a Yorkshire Man
This is going to be an amazing build series Cole. Looking forward to how it all progresses.
Can't thank you enough for your great channel. Fantastic stuff!!!
Glad you enjoy it! Thank you! :-)
Can not wait to see the videos, what a wonderful Project! With the upcoming videos, I can certainly learn something if I ever need to overhaul my Cooper S engine! ^^
Ant roll bar looks like a Speedwell
I have a supposed numbers matching 66 Cooper S (No reason to doubt. I'm only the second owner) I am just getting started with here in Delaware. I bought it from my brother-in-law after his dad died this past year. Not the pedigree this one has, but it did race out in California. This video was rad.
Look forward to watching this series!
I really enjoyed that good sir. some intresting detail there. That timing cover plate looks very Austin America ish
Maybe a stupid question. But is there a possibility you will refurb parts for this engine or other collaboration between you both?
Thanks Paul! Yeah I have another timing cover as well that I think might be the right one instead.
Not a stupid question. Let me send him some messages. I would love to get Paul on some of the machining work outside my tooling and skillset.
Look forward to seeing more of this
Wow, just wow
:-D
Looks like a great project for you. And enough to show, not just the "normal" rebuilding with new parts but refurbishing the original parts and making it almost as new.
Does the owner have performance figures of what it used to have and does he have an goal as what it will have to have again?
Thats a really good question I will have to ask if he does. I would love to get some old photos too of the car when it was being used.
Hmmm, You have helped me yet again. I believe I have that car in bits and pieces. My bonnet looks identical to that one. I made some video so I could ask people who may recognize the year and car. I thought I had the 67 but the shell does not have two gas tanks.
tHanks for all your great videos.
Not all Cooper S had twin tanks it was an option when ordering the car
@@ahartsclassicminigarage8833 tHank you. That is a starting point for me. I've got the doors as they were however the body was stripped of paint. the car pieces were mixed in with other cars.....I've got a few tons of parts... I started getting pallet racking together to sort out everything. tHanks again!
First time viewer. Liked/subscribed. You rebuild any A series engine? As in Sprite/Midget 948, 1098, 1275s? Say, out of a bugeye race car and street car? I have two I need to build, and about a dozen blocks/heads and will have to find someone to get that done.
Thanks for following the channel! I really appreciate it. I don’t do a ton of rebuilds as I do this mostly on the side. I have some contacts locally here that I trust very much, who could help you out. Shoot me an email classicminidiy@gmail.com and I can get you the info.
I have a bunch of engines and transmissions that came with a project mini I am working on. A lot of the engines don’t have any tags for the displacement. There are vin numbers and I was wondering how I can tell what engines and transmissions are even worth keeping to either rebuild or keep for spares. Any help would be greatly appreciated
The front plate is off an 1100/1300 not a mini. and the box is from the same car The plate has not been modified to take Cooper S timing gears which is quite fortunate as it is fitted with the wrong timing gears and chain,single row instead of duplex.You have to counter sink the 2 screw holes behind the lower timing wheel to fit the 2 countersunk screws needed for clearance
James you are correct My dad put the ordinal Mini engine in an MG 1100 and built the racing engine for my mother
Morris 1300 engine .
Odd with a pin drive camshaft .
Whats the casting number on the gearbox .
As i have a stack of gearboxes from a barnfind stash in new Zealand
The oil pressure relief valve on the S engine I am sure was a ball bearing not the plunger
An original cooper s sold for £18k in the uk last year . Sounds like a bargain right ? Well , every panel had terminal rust in the portion that hadn’t already crumbled to dust and they had to lift the car on a pallet . It wobbled like a rickety shed
Lucky you..
Simplex timing chain? ADO 15 Engine mount?
Hi Cole. I noticed as you took parts off the engine you just seemed to lay them down on the floor. Wouldn't one want to catalogue parts as they came off? ie. wouldn't you want the same pistons going back in the same cylinder it came from or does it not matter?
Hey I normally take everything apart and then inventory at the end however regarding your cylinder/piston question. The pistons wont be reused since the block will need a bore, normally I mark the connecting rods as they come out but these are all numbered from factory. :-)
My all time favourite is a MK1 Austin Cooper S albeit the 1071 version. Engine looks nice and clean inside - except for the piles of shite you found of course.
😎👍
Shouldn’t the timing chain be twin row on a Cooper S?
Yes after some further investigation it appears this timing side also came from the engine that donated the gearbox to the Cooper S block. Will have to be corrected during reassembly.
@@classicminidiy As you say, the timing chain and back plate are from a different engine; in the UK the Austin / Morris / MG 1100 / 1300 range had an additional forward facing engine mount on the timing gear backplate to limit the engine's fore and aft movement.
Cole, I am still trying to work out what that “dirt” actually was on top of the pistons..- were the spark plugs in or out when you first saw it?
If it was laid up with the induction off the head, and a valve was open, maybe a small critter found the way in?
Spark plugs were in I think Michael is right, I think the valves were open and someone found a nice little home in that cylinder hahaha.
Odd it has a single row timing chain.
From what I’m reading that’s actually normal on the cooper s engines. Still reading to confirm but it likely will remain simplex on reassembly.
p̷r̷o̷m̷o̷s̷m̷
I bet that the whole unit is from a Austin 1300 / America model - Heritage will prove that
I have the British Heritage Certificate and the engine is the original one. My dad took the original engine out and put it into a MG1100 when he built the racing engine
@@ahartsclassicminigarage8833 I dont dispute that you have the original one, but the one in the video has a 11/1300 gearbox and the engine also has a 11/1300 timing chain back cover to match -- typical for any in period engine swaps between 11/1300 and into Mini. Who/why would anyone add weight to a race car ?
@@MrJCTONE Yes it does have MG1100 gear case and timing chain cover my dad did that when he put it in the MG 1100
@@ahartsclassicminigarage8833 So there is a third engine ? - the one he takes apart is not the original - hence why the ID tag is removed.
The original is sitting on the floor.
@@MrJCTONE the one Cole is doing IS the original engine for the 1965 Mini Cooper 1275 S and I have the ID tag
Was there "dirt" in all the cylinders? Did a rodent get inside?
I think at some point it laid on its side and possibly allowed water/dirt to wash in. Then the dirt dried. Just a hypothesis though
That is not a cooper s gearbox .
You are incorrect
