Mk1 Capri - Cossie YB Advice Needed...
Morning All...
First time poster here.. Looks like a very good site...
I am currently using my Mk1 Capri for drift days and having some good fun, but would fancy a few more ponies….
I am running a 24V Cosworth V6 at the moment, with a 3.77 Final Drive in an Atlas Inc. LSD. I am happy enough with my suspension (Coilovers, 300 Llbs Springs, Eccentric Top Mounts, and Adjustable Bottom Arms) and a Caprisport 300 Brake Kit…
I am now giving serious consideration to fitting a Cossie YB for the extra grunt… Hoping the less weight will help the handling as well.
Option 1. There is a friend of mine selling a complete package from a 4WD Sierra, unfortunately, he has not heard it running and it has been sitting on his workshop floor for the last 4 yrs. He bought it in good faith from a guy who said it was running.
Had a look at it last night, it appears to be a June 1990 200 Block with a 4x4 Head. When i tried to turn over the engine manually, the crack would turn about 3/4 of the way around and then stop. It sounded like the crank hitting the sump (Big Winged Sump). We tipped the engine back on the big winged sump, and the engine then turned fully, but i could still feel the crank hitting the sump.
Secondly, the head was fitted with yellow injectors while it was running a turbo with a 0.60 housing... Looked huge... The Turbo shaft had some play in it as well.
Plug 1 was removed but i could not see anuthing in the cylinder...
Option 2. Another friend is selling a 2WD package for small money, but it looks like it broke a timing belt as their are marks on the piston where the valves have come in contact....
Option 3. WAIT for another engine/package to turn up for sale
I know this email maybe a bit vague, but i would appreciate any comments / advice PLEASE....

Hi and welcome to the site.
It's hard to say with those engines options what would be the best to go go for. The 4x4 engine is the better variant, but both of them sound like they need some money spent on them. Second hand Cossie engines are always a bit of an unknown quantity unless they come with the bills to prove, and even then there has to be an element of trust.
Personally, I'd buy whatever engine fits in your budget which still leaves you enough left over to rectify whatever might need replacing in a worst case scenario.

Lads, been reading many different opinions on the net, on which is the best cossie engine to go for in relation to drifting..
Was thinking of going for a 4x4 block/head/manifold, 2WD Sump and either a T3 or T34 Turbo with T5 Box... Was aiming to build a stage 3 engine.
By The Way...
I have been offered a complete package minus the Turbo from a 1988 2WD Sierra. The price is very keen but it looks to me that the engine broke a timing belt at some stage with the marks on the piston and head.
What would opinions be on this... I have been told that everything is there to rebuild it, am wondering would this be a could buy as i could start from scratch and build it, or should i stay a million miles away from a cossie with these marks on the pistons...




Haven't a clue on YB Cossie's, so would appreciate some advice...Cheers...

Its not uncommon on the YB to have valve/piston contact and will run ok like that however there does look like a nasty little chunk in the chamber and face area someone here would advise you on that more . The pics of the 2wd 88 engine looks like a reasnoable base to start but if it was myself i,d be having it apart and checking as your guessing . Aslong as the major pieces are all ok and machineable if nessesary then it does,nt have to cost the earth and can make a nice engine .
Can you check the bore size ? Does it turn over all ok ?

Hi mate.
Thanks for the reply. I haven't checked the bore size, but it does turn over ok...Will get that checked...
Would like to get an opinion on the head 'mark'...
The engine has been put back together by a guy who may not have put back on the big end caps in the order that they came off...
Also, valves etc have not been marked to indicate which order they were removed in...
Could this prove problematic down the road.. Literally....
Thanks

Welcome to PF, better getting them both checked mate by a decent engine builder but for your needs a 205 block will be fine with a T34/63 and set of seimens blacks and a balanced bottom end
Ps pics of your cars needed please

dont bother with that cylincer head, top left valve seat has been skimmed down too far as you can see the valve wont sit in properly as it should, its basically a useless cylinder head that needs repairing which will cost anything from Ł600 upwards depending where you take it
Hi Guys...
Thanks a mil for the feedback on the cylinder head on the cylinder head that i was going to buy...Really appreciate it..
Re 24V Cosworth Conversion.. To be honest, I wouldn't have a clue how to do it... that was i am looking at the YB as it seems to be a bolt in job...
Keeping a look out for a complete YB Package to bolt in...
I have a few Capri's, the Blue Capri is a Mk3 3Ltr (Road Car) and the Aubergine Mk1 is my Track Toy....
