Default Focus Cosworth

Good morning all..... Thought I would share a little tale of what has been going on in my life for the past year or so. But before I do I must say a bigh thanks to Jason "Jasesapphy". Without him the engine you are about to see would probably still be pissing oil and petrol all over my garage floor. Anyway, Jason - Thank you ! ! ! !

Right, where do I start ?. Well this started when I saw on Ebay a 4wd Fire damaged Cosworth Engine. I thought to myself that it was a bargain at £1700 and parted with my hard earned cash !. It was local to me at Poole so arrived home fairly quickly. It arrived when I was at work and when I got home all excited I opened the Garage door and thought "Oh my fookin god".

This was my new Cossie -





Is anyone else thinking "What the fook ?" Well I have no history of this engine or the car it came from. All I did know at the time was the Saph it came from was a 92 and it caught fire. But I wasn't worried, a friend of mine said his Mrs worked with a bloke called Jason who would be interested in having a look. I went to see Jason at his work place and pretty much at gun point (private joke, but almost reality) asked for a hand. And being the nice bloke he is Jason said yes ! ! !

So after a few weeks of scuttling round in the garage the engine, with the addition help of Ratty was stripped to its bare bones. Most of the fire damaged stuff was binned as it was all beyond repair and I got to think what am I going to do with this. I had a chat with a mechanic friend who said my project was ill conceived and lacked research but I prefer the trial and error approach to things. I wanted a Mk1 1963 Cortina but a decent one would be difficult to source and there were other issues relating to power output and shell strengthening so that idea was binned.

I then decided I wanted to put it in a Focus

Anyway, whilst I pondered the Focus Idea my engine sat in pieces on my garage floor whilst I hunted an elusive engine builder. People kept telling me he existed but it took a while for Jason to come up with his details. Anyway, when he did his name was Nick, and he owns Advanced Automotive in Bristol. And what a top bloke he is.

I took my engine to him like this -




It wasn't in bad shape, little bit of Piston Kissing going on but nowt major. Or so I thought

After a several month wait and a top rebuild my engine was returned to me with the following spec -

GOETZ Rings
ACL Main Bearings Heavy Duty
ACL Big End Bearings Heavy Duty
ACL Thrust Washer
ARP Big End Bolts
2 Kent BD10 Camshafts
1 Aux Shaft - Plate - Bearing
1 Two Wheel Drive Oil Pump
1 Belt Tensioner
1 Timing Belt
2 Vernier Pulleys
1 Ajusa Head Set
1 Ajusa Converion Set
1 Group A Ajusa Head Gasket with Uprated Firering
1 Copper Decompression Plate 1.2mm thick - 7.62 Compression Ratio
1 ARP Head Stud Kit
16 Hydrolic lifters

Cylinder Block degreased, crack tested and honed. Crankshaft crack tested and polished. Conrods crack tested and checked for distortion. Pitons measured for excessive wear. Degrease plus crack test cylinder head and debur caps and rails. Cylinder block surface ground 0.2mm from main face. Cylinder head surface ground 0.15mm. Reseat valves and fit new valve seals.

After all that my engine is home and eagerly awaiting its new car




Obviously the Rocker Cover needed sorted at this point but the engine is ready to built back up. The only thing I didn't like at that stage was my 200 Block has a 1ml overbore. But the head was in excellent condition so at somepoint later on I will probably replace the block and pistons. This engine is good for 350bhp - 380bhp. Eventually I may want more but that will do to start.

Anyway, thats all for now people. More to follow very soon. Chris[/img]
