Escort RS2000 4x4 2.0 Turbo Conversion

[JOHNDQ]

sod the haynes manual, have you thought about writeing a book, this is high detail at its best, love it, and thats coming from a lay man, keep it coming

 

lol they dont need to cover that sort of thing this sort of work isnt really done any more unless its like this build. Most engines are alloy now so bores are replaced with liner kits or have some form of special coating are once damaged are just throw away jobs like the rest of the trade has become. Anyway looks a good build hope have some dyno print outs when done

[lee grout]

Random question:

 

Why are the pistons set up as they are? I mean why are 1 & 4 up and 2 & 3 down. Is there a reason why its not 1 up 1 down in sequence??

 

 

 

 

 

Love these threads........as is you needed telling

[dalelc16]

Top dead center. Its the fire pattern

[blacksofstichill]

It's always nice when you have your freshly machined, cleaned and painted block ready!

 

Cheers, yes, it's good to have it sitting all ready for the build up and about to start taking shape.

Thanks, yes, there'll be dyno print outs for this once it's all finished, fitted and mapped and I'll be sure to pop them up on here.

Thanks, glad you like the threads! Yeah, as said below it's just the way the crankshaft is on these and the firing order is to suit that, 1 and 4 are at top dead centre as 2 and 3 are at bottom dead centre.

 

 

Top dead center. Its the fire pattern

Cylinder Head is now down to a bare casting and ready to be cleaned up -

 

http://blackengineering.co.uk/images/Doctor-Evil-RS2000-Turbo-Engine-Rebuild/0216.jpg

 

http://blackengineering.co.uk/images/Doctor-Evil-RS2000-Turbo-Engine-Rebuild/0217.jpg

[scottybo]

i had a bike once with 2 cylinders and both of them went up and down together, on different strokes of course though

[blacksofstichill]

Although the head had some surface corrosion I was hopeful it would clean up okay, unfortunately it was much deeper than I'd expected and extended out quite far from the waterways in the head -

 

http://blackengineering.co.uk/images/Doctor-Evil-RS2000-Turbo-Engine-Rebuild/0218.jpg

 

It's hard to see from the photos but some areas will be around 1.5mm deep

 

http://blackengineering.co.uk/images/Doctor-Evil-RS2000-Turbo-Engine-Rebuild/0219.jpg

 

http://blackengineering.co.uk/images/Doctor-Evil-RS2000-Turbo-Engine-Rebuild/0220.jpg

 

You can see here that unless the head was welded up in all of these areas and skimmed back, the Head Gasket wouldn't stand a chance of sealing the combustion chamber from the waterways -

 

http://blackengineering.co.uk/images/Doctor-Evil-RS2000-Turbo-Engine-Rebuild/0221.jpg

 

http://blackengineering.co.uk/images/Doctor-Evil-RS2000-Turbo-Engine-Rebuild/0222.jpg

 

Since the actual head casting itself is standard (not ported, etc) and in need of so many areas repaired it was decided that the most sensible solution would be to start afresh with another head so we have a good casting to start with and build all of the valve train from the original one into it.

 

I delved into my stores and unearthed this one. I removed it from a Car I broke a few years ago, skimmed it and sold it but ended up owning it again when I bought the car it was fitted to with a knackered bottom end. I knew it was a good head and it wouldn't need skimmed again having only done around 1000 miles since I sold it. At this stage it's just as removed from the car -

 

http://blackengineering.co.uk/images/Doctor-Evil-RS2000-Turbo-Engine-Rebuild/0223.jpg

 

http://blackengineering.co.uk/images/Doctor-Evil-RS2000-Turbo-Engine-Rebuild/0224.jpg

 

I didn't take any photos of the stripdown since it's exactly the same job as I'd just done on the original head, here it is all stripped down to a bare casting -

 

http://blackengineering.co.uk/images/Doctor-Evil-RS2000-Turbo-Engine-Rebuild/0225.jpg

 

http://blackengineering.co.uk/images/Doctor-Evil-RS2000-Turbo-Engine-Rebuild/0226.jpg

 

http://blackengineering.co.uk/images/Doctor-Evil-RS2000-Turbo-Engine-Rebuild/0227.jpg

 

http://blackengineering.co.uk/images/Doctor-Evil-RS2000-Turbo-Engine-Rebuild/0228.jpg

 

And after an initial clean up and degrease, this isn't a final clean up but it's looking much better already, this one has some minor corrosion to a couple of waterways but having had the gasket laid in place it's all within the gasket area and will have no problems with sealing. -

[lee grout]

Detailed as ever. Keep it coming

 

Would 1.5mm of been too much to skim off then?

Edited July 6, 2013 by lee grout

[Ahmotorsport]

Detailed as ever. Keep it coming

 

Would 1.5mm of been too much to skim off then?

For a turbo motor, oh yes!

[blacksofstichill]

Thanks yes if it needed 1.5mm taken off it would raise the compression ratio too much on this unfortunately so it meant that the original head casting was scrap.

 

continuing with the valves, I got the first of the Exhaust Valves onto the lathe -

 

http://blackengineering.co.uk/images/Doctor-Evil-RS2000-Turbo-Engine-Rebuild/0244.jpg

 

And Polished it all up -

 

http://blackengineering.co.uk/images/Doctor-Evil-RS2000-Turbo-Engine-Rebuild/0245.jpg

 

http://blackengineering.co.uk/images/Doctor-Evil-RS2000-Turbo-Engine-Rebuild/0246.jpg

 

Then moving onto the inlet Valves -

 

http://blackengineering.co.uk/images/Doctor-Evil-RS2000-Turbo-Engine-Rebuild/0247.jpg

 

And all polished up -

 

http://blackengineering.co.uk/images/Doctor-Evil-RS2000-Turbo-Engine-Rebuild/0248.jpg

 

http://blackengineering.co.uk/images/Doctor-Evil-RS2000-Turbo-Engine-Rebuild/0249.jpg

 

All the Valves polished up -

 

http://blackengineering.co.uk/images/Doctor-Evil-RS2000-Turbo-Engine-Rebuild/0250.jpg

 

http://blackengineering.co.uk/images/Doctor-Evil-RS2000-Turbo-Engine-Rebuild/0251.jpg

 

They're not in bad order but there is still some pitting so they'll have to be refaced -

 

http://blackengineering.co.uk/images/Doctor-Evil-RS2000-Turbo-Engine-Rebuild/0252.jpg

 

http://blackengineering.co.uk/images/Doctor-Evil-RS2000-Turbo-Engine-Rebuild/0253.jpg

 

Exhaust valve onto the Valve refacer -

 

http://blackengineering.co.uk/images/Doctor-Evil-RS2000-Turbo-Engine-Rebuild/0254.jpg

 

And refaced -

 

http://blackengineering.co.uk/images/Doctor-Evil-RS2000-Turbo-Engine-Rebuild/0255.jpg

 

http://blackengineering.co.uk/images/Doctor-Evil-RS2000-Turbo-Engine-Rebuild/0256.jpg

 

Inlet Valve ready to go onto the refacer -

 

http://blackengineering.co.uk/images/Doctor-Evil-RS2000-Turbo-Engine-Rebuild/0257.jpg

 

And refaced -

 

http://blackengineering.co.uk/images/Doctor-Evil-RS2000-Turbo-Engine-Rebuild/0258.jpg

 

All Valves now cleaned up, ploshed and refaced -

 

http://blackengineering.co.uk/images/Doctor-Evil-RS2000-Turbo-Engine-Rebuild/0259.jpg

 

http://blackengineering.co.uk/images/Doctor-Evil-RS2000-Turbo-Engine-Rebuild/0260.jpg

 

http://blackengineering.co.uk/images/Doctor-Evil-RS2000-Turbo-Engine-Rebuild/0261.jpg

 

Starting to lap in the valves now -

 

http://blackengineering.co.uk/images/Doctor-Evil-RS2000-Turbo-Engine-Rebuild/0262.jpg

 

http://blackengineering.co.uk/images/Doctor-Evil-RS2000-Turbo-Engine-Rebuild/0263.jpg

 

First one done and the dark "band" where the valve is sealing can be seen all around the valve and the seat -

 

http://blackengineering.co.uk/images/Doctor-Evil-RS2000-Turbo-Engine-Rebuild/0264.jpg

 

http://blackengineering.co.uk/images/Doctor-Evil-RS2000-Turbo-Engine-Rebuild/0265.jpg

 

Halfway there now -

 

http://blackengineering.co.uk/images/Doctor-Evil-RS2000-Turbo-Engine-Rebuild/0266.jpg

 

All done -

 

http://blackengineering.co.uk/images/Doctor-Evil-RS2000-Turbo-Engine-Rebuild/0267.jpg

 

http://blackengineering.co.uk/images/Doctor-Evil-RS2000-Turbo-Engine-Rebuild/0268.jpg

[sidrick]

As usual, top update! Get some gloves on though

[blacksofstichill]

Sorry, I've still not started wearing gloves for work, can't see myself changing after all these years!

 

After lapping the valves into the head I moved onto the hydraulic tappets, here they are as removed from the original head, as you can see, some of them have rusty marks on the surface -

 

http://blackengineering.co.uk/images/Doctor-Evil-RS2000-Turbo-Engine-Rebuild/0269.jpg

 

Most of them were just stained but 4 of them had corrosion into the surface which meant they were no good to be used again -

 

http://blackengineering.co.uk/images/Doctor-Evil-RS2000-Turbo-Engine-Rebuild/0270.jpg

 

The Hydraulic Tappets that were fitted in the replacement head were an earlier design and I wasn't happy mixing and matching the two types of tappet and ideally wanted them all to be of the later design. So, digging into my spares I found 4 good tappets of the same later design to replace the corroded ones -

 

http://blackengineering.co.uk/images/Doctor-Evil-RS2000-Turbo-Engine-Rebuild/0271.jpg

 

So, we now have 16 tappets which are corrosion free -

 

http://blackengineering.co.uk/images/Doctor-Evil-RS2000-Turbo-Engine-Rebuild/0272.jpg

 

But, I didn't leave things at that, because the engine has been sitting for a good few years I stripped the tappets down to clean them -

 

http://blackengineering.co.uk/images/Doctor-Evil-RS2000-Turbo-Engine-Rebuild/0273.jpg

 

As you can see, there was some slight staining of the working surfaces and this is what we wanted to get rid of -

 

http://blackengineering.co.uk/images/Doctor-Evil-RS2000-Turbo-Engine-Rebuild/0274.jpg

 

http://blackengineering.co.uk/images/Doctor-Evil-RS2000-Turbo-Engine-Rebuild/0275.jpg

 

http://blackengineering.co.uk/images/Doctor-Evil-RS2000-Turbo-Engine-Rebuild/0276.jpg

 

With all of the Tappets completely stripped down they were thoroughly cleaned in degreaser and the difference was quite noticeable -

 

http://blackengineering.co.uk/images/Doctor-Evil-RS2000-Turbo-Engine-Rebuild/0277.jpg

http://blackengineering.co.uk/images/Doctor-Evil-RS2000-Turbo-Engine-Rebuild/0283.jpg

 

With all of the tappets cleaned up I put them back together -

 

http://blackengineering.co.uk/images/Doctor-Evil-RS2000-Turbo-Engine-Rebuild/0284.jpg

 

All 16 Tappets rebuilt -

 

http://blackengineering.co.uk/images/Doctor-Evil-RS2000-Turbo-Engine-Rebuild/0285.jpg

[lee grout]

Nice update How careful do you have to be when refacing the valves? If you buzz then down to remove all the pits can you go 'too far' and ruin them?

Also, what do tappets actually do?

[scottybo]

yes u can go too far. obviously the main issue would be if you make the valve too thin and then when u fire it up its too thin to deal woth the pressure and the like....and gives up and falls apart
