I was thinking of the proper Cosworth ones actually. Recent communicae with them have not revealed any big power figures, but they're working with the lunatics in Norway and Malta to do some 4 figure stuff, hopefully. There are various custom options available; tall blocks, nikasil liners, special long studs (not the same as 'wrc' ones, block is different/better)..

Unfortunately the blocks come in at $6,000+options.

 

I thought the problem with the Turkish blocks was todo with wall thickness between the bores, if to fit the liners you have to machine that out anyway surely any block would be just as weak. Or is it that the overall casting is weaker due to the casting process, if your going to be running liners again dave you may manage to pick up a cheaper block that has damage to the standard bores.

 

When i enquired about fitting nikasil liners the boring companies didnt recommend fitting the liners to overbored or scrap blocks.

 

Strange as i thought to fit the liners you would need to bore all the material away anyway.

 

my understanding is that to fit these liners they will be machined to a set sise and the liner shrunk in

 

You do, and it is a bit of a strange statement. The only thing I could put it down to is an overbored (1mm+) block may potentially be structually weaker after abuse.

 

Bang on no strength left in the block !

The liner becomes the block clamped down by the head, the liner is more like a wet liner on french engine.

 

yeah most sensible thing said that and most realistic money wise really without spending daft amounts again

 

Are the nikasil liners just steal liners with a nikasil coating to healp deal with the heat and friction of a big power engine or are the actual liners different. I know when a lot of my mates raced 2 stroke motocross bikes we use to send the barrels away to be nikasil coated. If you could find an original bore block and have it coated would it give less flex (as your then dealing with one original casting not a casting with a friction fitted insert)but with the same benifits.

 

No probs

 

gutted for you would be a real shame to see it get bust

as porkie said stop chaseing 200 youv already been a lot closer than most & just get a moter in it so you can enjoy the car 500bhp is plenty for a road car

 

you know my feelings on the matter mate

 

Gutted for you

I would love to see Yum crack 200mph, but it comes down to how much you wanna throw at it. If its what you want, go for it.

I spoke to Cosworth about the alloy block, they said it was'nt aimed at engines producing very high outputs. If memory serves, the fella on the phone said 500bhp was the limit for them.


Best of luck with the car, hope it doesnt cost you a silly amount to put right.

 

did you say pete mason in north london waltham cross /waltham abbey

 

Sad to read this! Hope you woun`t give up!

But goes to show I`m not far off when I recomend people to use a genuine cossie 205 block rather then a Turkish 200 block..

 

EBB flowtech power in stavanger have Ultrasound scans of all the variations of cossiblocks, he havent had time to compare all the data yet, but he should be able to uncover the myths of this old block..

 

Sounds about right... At the moment the car does not seem to be fun, when it stops being fun do something about it or break it

 

Dave,

I'm very sorry to hear somemore bad luck coming your way, I think a bit a reflection is needed now.

I'm sure you had a diary full over events you wanted to attend in Yum this year and something like this is a real kick in the bolocks for you and Helen, 200 mph would be a great thing to have on your CV and I'm sure everyone else would agree but you've just cracked 194 and I can't see any privately owned Escort Cosworth owner coming close. If 200 is your goal and nothing else matters then accept this as a low to the highs you'll achieve in reaching this, but if you want to have a car that you have available more than not maybe it's time to stand back and be proud out what you've already achieved and show it off at these places.

Good Luck, Warren

 

the bottom line is that it all depends on dave's ability to fund the next level of tuning/rebuilding

if he knows that, for the sake of Ł5k being spent he can flog the car for Ł35k and there is someone willing to buy it then fair enough

but if it's only worht Ł25k after having spent Ł5k on it and it's worth Ł30k in bits without spending the money, you have to start thinking

if it were me, personally, i'd bolt in a standard engine, transmission and sell the car as a going concern and all the other bits that would make big money would go to one side and be sold seperatly

then again, i think i could afford to getit fixed and go on from there, but not knowing dave's situation, or, more importantly, his drive and willingness to go to the next level, i couldn't say anything for him

 

Fuckign gutted for you Dave, all was going well too, or so you thought!

Chin up mate, a few days to think it over and regain some enthusiasm and you'll be fine, YUM is nearly there!

 

Shit news Dave

 

Dave it would be a shame to give up now by reading all your posts 200 mph means alot & lets face it your not a kick in the bollocks off it.But i know how pissed off i get
spending cash on cars so i see where your coming from.Hope you make the right decision

 

Sad news -

 

Dave,

I reckon you should find yourself a std size bore s'hand block, bore it to 91mm with new pistons and re-assemble. Obviously the replacement block will need machining for long studs but it would be cheaper and a much quicker option, depending on Marks work load you should be able to see it back on the road in 2/3 weeks.

 

Really gutted for you Dave!

Maybe its time to find a new challenge?

Alex

 

Without the liners you mean?

 

Bad News I am yet to experience this happening to me..

but i am sure it WILL ONE DAY

.

 

No I wouldn't.

Lee's car was just over 600hp for years and hasn't missed a beat and it only ever gets driven hard and that does not have liners. That's just one example, there are loads more.

 

Im unsure of Mark's reasons for choosing the liners, obviously in a rally car they are there largely because of the agressive antilag but Dave doesnt have that issue really.

 

gutted for you Dave

im in the same boat as in the fact just found out my engine need an overhaul and am also going to miss the show season yet again

 

bad news dave so your in the MAD engine rebuild que then you will have plenty of time to save up !!!!!!!

 

Wounded for you Dave, but its nobodys fault i guess, this sort of aggro is to be expected when looking for reliable big power from these old YBs.

After yet another Kick in the cock from a big power YB, maybe its time for you to buy a Lancer?

 

Makes sense from a performance point o view but IMHO there is no way that would put the same smile on dave and helens face to look at and own etc though

Their ford to the core the poor bastards

 

PORSCHE or BMW!

Daves old now dude!

 

I actually typed BMW to start with, then decided he is too hardcore and re-typed lancer.

 

I know how you feel Dave, you spend the money on the best parts available, and then get let down through no fault of yours or Mark's.

If you go the non-linered route, you DEFINITELY will need to turn the boost down . I would imagine that the huge boost spike that you run is not doing the engine (or transmission come to that) any favours for longevity .
