LSD, a good choice for fast road is a quaife LSD, it's very user friendly and no after adjustments required ever, unlike the clunker fomospo type . 3J, pricey for no extra gains.. which ever one you decide it'll be great fun getting the RS to slide ! I'm doing some research on the new brand on the block which has been used in drift cars and truck racing etc , look up Black Line LSD , they were cheap but are on par with quaife etc for performance... I'm thinking of getting one for the mk1 at a later stage..

RS 4 spoke update, I was told the next batch will be in store around March so if you want a set, get your name on them, first in with cash he gets them

Blackline I looked at a little while ago actually so it's good to know they have some chops. Also Palmside in NZ sell them.

With the wheels I am still on the fence, it's good to know that he is getting them in though. 

I was out in the garage again today, pulled the engine out and stripped it down. The hope was to just giving it a quick look over to make sure everything was good, hone the bores, get it decked and then put it back together. Unfortunately though the engine shop who did the rebuild - which has done less than 5000km - did a absolute butchers job on it. I am beyond annoyed. I have no recourse though because the job was done when I was 19 - almost 20 years ago.

Two burnt exhaust valves, scuffs on every cylinder wall and piston skirt, 1 and 4 conrod bearings scuffed and what looks to be and incorrect thickness thrust bearings to boot... Part of me is glad I stopped driving it when I did, so good work younger me. I can't imagine the extent of the damage if I kept driving it. 
 






Thankfully the crank looks ok and I still have some meat in the bores so it's salvageable. Wasn't expecting a full rebuild but hey here we are.

Happy New Years Everyone. My resolution is to get this car back on the road in less than two years !

After drowning my sorrows with a few glasses of red it was back to it. I've wrapped and numbered the engine bits and chucked them in a box. In a few weeks I'll be dropping the lot down to a place called Pearl Engineering, they've been recommended from multiple people so I'll get them to cast an eye over and give me a report on what needs done.

In the meantime I cracked on with the front calipers. We had a nice morning here so it was time to clean them up and paint them. 

 
 
Getting all the gunk off took a good hour with the brush and wire wheel. Once they were clean I hit them again with some thinner then acetone to get the last remaining residue off. After that I hit them with two light coats of caliper black, then a final thicker coat.
 

 


 
They've come up pretty good, I picked up four new pistons and a new rubber kit from Yesterford today and I've got a spacer kit coming for them so I can fit vented rotors on the front. I think they'll look nice with the contrasting pins and clips etc. I'll also hit the rotor hats and edges with the same paint once once I pick them up. Same with the rear calipers once I grab them.

That engine internals looks like it's played a stage or 2 in the Dakar Rally !
When you mentioned the thrust bearing, it brought back a memory of when I used to thrash the life out of my mk2 pinno, then sitting at the lights waiting I heard what sounded like a small bell in the crank case... It quickly went away after a few seconds but since then each time I press the clutch pedal it caused the revs to drop, I knew straight away what happened but kept driving like a loon for 6 months till I got a good motor built to swap out. Once the rattler was removed I dropped the oil and sump, there it was, a twisted half thrust bearing in the shape of a ch2 logo, lucky no mess or swarf etc was found so I installed a new set of thrust bearings (next size up) and sold to a mate who also thrashed it for years after without any problems. Pintos are a tough little engine ..

That's a spot of luck , never good finding bits like that in the sump!

The thrust bearing out of mine barely had contact wear on it - only on one half right on the edge, it probably needed one size up minimum. 

All the new bits are in the calipers and they're on the bench curing so I started on the diff today. Stripped it back to metal, cleaned it and hit it with some heat to get any residue off then a brushed on a few coats of KBS. Not 100% happy with how it leveled out so far. I'll probably let it cure, give it a slight rub back and then give it another coat.

Thanks for the progress updates. The garage looks like a good place to be, always half the fight keeping it clean and organized.
Bummer to hear about the engine but on the upside you'll have some piece of mind when its all put back together properly.
For things like the diff housing, springs etc have you thought about powdercoating? I do it with all my stuff nowadays, cost and time wise it works out cheaper in the long run and its as tough as boots.
The KBS stuff is good but I've had it flake off in sheets on a couple of bits, they really need to develop a primer to go with it IMO.

Hi Guys, funny you mention the KBS rust seal and blacktop.
I have trouble getting a good a good finish in the warmer weather so probably should look at getting some of their thinner?
On bits under the car I don't fuss too much but I'll be interested to know how the diff comes up if you do scuff it up and re-coat it Mark. It certainly looks okay in your photo. Better than mine done with rust seal
 
I have only had one thing bubble on me once (fuel tank) and I know it was thoroughly clean. I just cut out the section which was bubbling (about 50x50mm) cleaned it, re-coated and never had another issue.

I am going to get the fuel tank dipped and powder coated - same with all the smaller parts. I decided to just give it a crack considering KBS had some good reviews and the diff seemed like the part to give it a shot on. If I can't get it as smooth as I want I may bite the bullet and strip it again and get it powder coated. 

I'll be giving it a test rub in the morning so i'll post an update tomorrow arvo if it works out. Nothing ventured nothing gained. 

At the end of the day though its under the car and already looks 100x better than it did . Eventually i'll need to make up new brake hard lines and brackets when I get the rear calipers etc too so if the KBS turns out good with this I can use it on all the little one off brackets that I make up.

^^ that Minisport website was a bit of a good find.
Having someone in Aus selling JBW's is a bonus.
I'm happy with their minilight repro that I got for the 4 door.
 
They were pretty safe 13x6, but had to be bought from Race and Rally in the UK, as no Aus dealers at the time.
Your Minisport mob would have worked out cheaper.
I think you are way on track for a 2 year turnaround.
 
And 2 month is looking quite possible also...:)

Hahaha I'm back at work next week so things will slow down once that happens. Plus the in-laws are coming over from England in Feb for a month so there wont be much car time over the next little while. Hence why I'm trying to get stuff done now!

NurseBetty accross on oldschoolford has awesome wheel fitment on their car - standard arches, looks really really sharp and they're 15s.... too many choices!

Ok I think I've cracked the KBS code - I sanded the whole thing back with 600 grit wed and dry, dried it off, cleaned it then used a new 5mm microfiber mini roller that's been washed in thinners and dried out.
 
Use the edge of the roller to get in the nooks and crannies then smooth it out and back roll - just like painting a wall. Came up really well and that's just one coat, I'm going to let it cure for a while, nock the nibs/dust off with some 1200 then do one final coat.

That casing looks too good to be disappeared under a car 👍.
I did paint the casing on the yellow lugger van in 2pk sniper black, a Focus colour and all the hard effort vanished when it's bolted up and hidden...

I know right . It's a sickness.


Last coat on - now ill let it dry then hit it with a light cutting compound in a few weeks for science. 

So the process applying the KBS from start to finish.
 
1. Full bare metal rub down, used wire wheel and stripping wheel on the grinder.
2. Cleaned with thinners then used a blowtorch to burn off any remaining residue.
3. Two coats brushed on, wasn't happy with finish so rubbed it back with 600 until smooth then cleaned with water then fully dried.
4. Applied one coat with 5mm microfiber mini roller, back rolled over it. The product is VERY forgiving, it has a long open time, I went back to the start to touch parts up after about 3 minutes and it still leveled out nice.
5. Allowed to dry for twoish hours until touch dry then gave it a VERY light rub with 1200 to knock the dust and a few other bits of crap off the surface.
6. Applied last coat same as step 4.
 

 
It's not perfect but I'm a lot happier with it now - I don't think I could have left it the way it was. Once it's had a light buff I think it'll come up even better. The diff casing will be painted matt silver which I think will make it pop quite nicely, Ill get the tramp rods and leaf spring brackets/shock mount powder coated matt silver too.

are you sure your happy with the finish? :)
Definitely wasted unless you can include some stick on mirrors around so we can see the efforts of that hard graft.
 
I think the majority of posters here have a sickness as you mentioned.
For some its polishing shiny bits to within an inch of its life.
Mine is always doing things twice, and not listening to those who give good advise in the first place.
 
With the rello''s coming out, have you though about paying for some extra carry on, and asking them to swing past Burtons on the way over?

You only know it's done right when you do it wrong first !

I did consider it! I'm headed back there for Christmas this year I think, the partner wants to spend it with her parents this year. By then I should be far enough along that I'll have a "definitive" list of what I'll need and organize it while I'm there because postage stacks up so fast. 

A pallet can be organized for a reasonable price but sea freight takes ages. I am going to try my best to source everything locally but there's just so much on offer there that you cant get here.
