West of Scotland RSOC

here's the progress I've been making on some upgrades on my Escort RST S2...



after the summer I put the escort in the garage for a bit of restoration and to install the 2.0ltr zvh I've been building in my spare time this year..
up on stand ready for the work to start..


I picked up a low mileage st170 bottom end from a online auction for a very good price



and took it apart for some fettling . .




first thing was to clean the block up, clear all the oil galleries and give it a coat of red engine paint



so far ive rebuilt the bottom end with new bearings, gaskets, full set of ARP fasteners all through.. rotatioally balanced the crank, flywheel, and clutch cover and reassembled it


balanced crank back in with the new bearings

I'll try and keep this updated as i go along with the rebuild

NICE ONE PETER,WHAT SORT OF POWER ARE YOU LOOKING FOR OUT OF THIS

Looks good! What are doing about turbo and management etc on it?

Nice engine upgrade to match its looks Peter. Diamond Cuts look right at home on the S2

lookin good

looking good m8

time for a wee update
with the block and balanced crank assembled it was time to put the rods and piston's in...


these are the st170 rods and mahle pistons, me and my dad machined 1mm off the top using a milling machine to reduce the compression ratio I had to order new rings from Mahle in Germany coz they are different from normal zetecs pistons.

installed pistons and rods ->


the st170 sump is the 2 piece sump like the Black-Top zetec's, these will work well in the Series2 RST but i put some inlet unions in for the oil returns from the turbo at the front I drilled through cast in mounting bosses that are spare in the side of the upper sump and drill and tapped for some unions


return from breather system in the back->



Will get some more pictures of the progress when i get chance to download them

you dont cut any corners peter al give you that av seen this car when it had old engine and it was mint now youve got even more power keep them coming mate

well done m8 looking good

cheers guys, hoping for a nice reliable engine that will last well. . . and give a nice power increase too

fancy building another 1

yeah sure, I'm starting to get the hang of putting zvh's together if i could build engines for a day job i definately would

mint mate, lookin forward to seein it go!

time for another update...

I had the st170 sump powder coated and bolted on



i put the flywheel on, its an rs turbo 220mm item, i had to drill the flywheel bolt holes out by 0.5mm to 11mm..



...with an AP cerametallic clutch

Then i moved onto building the Stg3 Big Valve cylinder head up..


nice big stainless valves, brandnew rockers, collets and aluminium valve spring retainers


this was the engine in the stand, i timed the Piper285t2 cam up using the vernier, sorted out a few bits and bobs and got it ready for installing into my Escort . . .


which is what i did today ->


engine installed on its mounts..


hope to have it ready to run soon

Looks awesome Peter well done mate


Meant to ask you last night, what engine management are you planning on running

Not long now peter, great new set up you have there.
Should be nice and reliable now!!

hello,

thought I'd start up the rebuild thread for my Series 2... so now its the re-re-build thread

story so far -

I started building a full 2ltr zetec turbo and doing a bit of restoration work including seam welding in preparation for some big power

I started by taking out the standard fuse box and repairing the bulkhead





the fuse box will live inside the car now

then it was the turn of the battery tray to come out, when i took this out the joint between the inner wing and passenger footwell required renewing




edge of bulkhead above brake servo mount

Where the bulkhead meets the inner wing needed a wee repair too



and from the outside (yes i did cut a big hole in the wing )



repair patch made



tacked in



fully welded




and some seam welding done too
