does anyone do them? What's the most you can take them out to?

 

heard of a few 2.3's and 2.4's
martoons escort uses a longer stroke, not sure if he does a kit, try askin him(reyland)

 

tar mate

 

2.4 is the norm
millington race engines have been known to do a 2.6 conversion on a yb how safe or reliable is anyone's guess.



Regards Doug.

 

2.150cc is as big as I would go.

Didnt collins used to offer a stroker kit many moons ago?

 

i thought that rods saph was a stroker mark

 

are they worth doing?

 

Yes it is 2.150cc.

Mark

 

do you know the car in your sig?
i know where it is now and am thinking of buying it as a track car?
sorry for the hijack

 

All depends on what you want out of it and the budget you have, as there not cheap.

Mark

 

we do 2.2/2.3/2.4
dont do a kit as such just build to what the costomer wants

 

chorley street geoff had a 2,4 stroker in that cossied tranny mate, migth be worth a chat with him hes a sound lad

 

fair one should have took your original comment mark ha ha

As he sold the tranny?

 

I can supply these, give me a call if you need info.

 

I didnt think he did? I thought he just used a block with a higher deck height and longer rods for a safer rodangle(?) so it could rev

 

powers used to do a 2.4, collins done a 2.3

 

My engine uses an 84mm stroke crank and longer rods these together with a much taller block make for a superb bigger capacity engine.

 

Aren't strokerkit's really popular among evo-owners ? Why not on a yb ?

 

what kinda price we looking at martin ??

ballpark or specific ???

just curious


beef

 

Am tryin to find out as much info as my boss is building a mk2 with a Cossie and wants a stroker thanks for everyones help!! What sort of price are they martin?

 

Depends if you go for the linered bore option, if not then about Ł3k plus vat gets you crank, rods & pistons.

 

Martin my engine isnt going to be linered but is a stroker as we have agreed but what is the low down on liners, does it make the engine more reliable?? Or is what ive got more than enough and reliable for the bhp output?

 

Collins has always done the 2.3 conversions ,a company called Suhe in Germany did 2.5's on escort cosworths and they were tuved and a ford dealer too, heres a spec of a Suhe Turbo Technic escort cos

Whats the rod ratio on this engine?

 

I would avoid the old 2.4 engines like the plague, as they use SHORTER rods than standard, so combined with a big stroker crank, the rod angle goes to rat shit and they get horribly vibrationary above 5500rpm (ideal for towing caravans though ).

The best stroker conversion is obviously one that uses a rod angle BETTER than standard (or no worse at the very least). The only way to do these with any big success is to use a taller block. You then have the best of both worlds - improved rod angle and larger capacity.

My own engine is a half way house, it has fractionally better rod angle than standard and with a bigger bore (93mm, which is the limit on a standard linered block IMO before wall thickness becomes an issue), and with a 82mm crank and custom rods (8mm longer than standard) and custom pistons (shorter compression height), it achieves 2225cc.

 

for about a week at a time

 

The only real issue I had was the first time we tried to use a 93mm bore on a standard unlinered (albeit early thick wall) block.

This was cured with liners.

We then had the exact same issue as Martin with a certain supplier's crank, where the nose fell off the crank .

Since these issues have been resolved, the car has been bullet proof .

 

I have done several strokers without liners but I don't go too big on the bore size. Yours will be fine.

 

is the tall block engine like in your escort available yet or is it a one off if so what sort of money would one off those set you back?

 

A bare block with liners installed would cost about Ł4k plus vat.

 

Standard bore, 8mm higher piston pin, 5mm longer rod, 83mm stroke.

Sorry to go back a bit, (i think someone else asked this question), but why dont these 2.3 and 2.4 strokers get used as much on cossies, when it seems they do the world of wonders for the evos boys

Is this down to money sides of things or is jus because there is no real need to go that extra capcity, and to just be done with a longer throw on the rods ??

 

Totally different engine has a bit to do with it. Different Stroke, bore etc all has an effect on this.

 

Rods is 1.60.... a std YB is 1.66, mine is 1.80.

 

mark, going by martins calculations being rods is 1.60 why is this ?

 

1.8 is very good, whats your capacity, i guess you run a different bore size? (sorry i'm not really into the cosworth scene just comparing to other car's), how many RPM's are you doing?

I'm currently running 1.5 rod ratio on a honda, and revving to 7800 rpm's. (standard rod ratio, limiter is 7200 standard on this engine)
