I want to build up a cossie engine. My mate has a 200 block in his workskop which i can have for a small price or I can use my old 205 block which is alo in the workshop, but this needs to be wire rung which I have been told will be around 400 quid.

What are the pros and cons or wire rung blocks?

Is it better to use a 205 wire rung block as opposed to a normal 200 block?

Will be using 4x4 cossie pistons to get the comp down 7.8:1.

 

wire ringing works with any block.

you should be using the 200 block and geting it wire rung if thats what your after.

 

wire ringing won't cost anywhere near Ł400 either,i'd expect Ł150 at the most.

the idea is to increase the sealing of the fire rings on a standard or group A gasket (fibrous type)to prevent them blowing out,
a 205 block in a 2wd car would be fine for decent power,mines working fine at over 400bhp anyway.

The 200 production blocks aren't that much better than a 205 really,but they are slightly better,so i'd use one and keep one spare

a WRC headgasket would be better than Wire ringing also,but at Ł370 ish they are a little dear,but they are fit and forget (provided they are fitted to perfectly flat surfaces)

 

i have a 200 block in my car at present but i wanted to build an engine for knowledge and also to chuck it in some shitter that i can rag about.

I know the 200 block is stronger but is there really that much difference between that and a 205. The 205 is free and the 200 block will have to be paid for.

Ideally im thinking of stage 3 or greys and thats it really. T34, stnadard cams, 4x4 pistons, 2wd head. Pretty basic really but shoud be good for 340-370 bhp at least.

 

see my reply above then

i'll be running 450bhp maybe more soon hopefully,and i don't expect any problems tbh.

i actually hear of more cracked 200 blocks than i do 205 nowadays too!

if that's all you want to run (370bhp) then a 205 will be fine,my old car ran T34.63/Greys/2bar on a 1mm overbore

 

a 205 block is more than enough for 400bhp so im sure it will be fine.

Got my eyes on another turbo which is slightly bigger than a t34 and is cheap cheap brand new too that should piss 400 too.

 

Andy Fisher wire rung my block for Ł80 its not cheap because its quite

time consuming

 

That is cheap tho LOL

I reckon Martins on the low end- I would have thought 250 was about right..

 

Ł400 to wire ring a block That's got to be more than just wire ringing, surely?

Try Mike R...

 

is not that much to do it.

is this not a compass type tool that sits in the bores and you score the block face by twirling it round....like a compass to make circles.

oh and a bit of mig wire.

and i believe once its done the block has to have this wire in all the time,therefore not being able to have a metal gasket on.

sure someone will correct me.

 

as above only wire ring if useing a group a,its the old way of doing it,steel multilayer replace all that now,spend Ł100 on a cometic but make sure your block and head surface are like glass

 

correct on all counts,although it is a skilled task that requires a bit of patience and finesse

Fisher charged me about Ł80 too,but as you and i both know Ad,he doesn't do these things for his own personal gain

I think the going rate is Ł150?

 

my block is wire rung i and i wouldnt change it.

 

was told by the previous owner of my mk1 that the engine had been wire rung, always wondered what it was for lol

 

I actually meant 400 for a linering

should stated linering in the subject not wire rung?

Whats the pros and cons or linering a block? Obviously they wont be nikasil liners due to cost

 

Bit of a difference between the two Ran

Why does the block need linering? For Ł400 I'd seriously be thinking of adding a bit more and getting a new block, or go for the 200 block if it's ok?

Linering is a way of reclaiming a block, but the company has to have had experience of doing it, and preferably on a YB (imo) - liners are common on V8 for example - doesn't mean their method will be ideal for a rapidly heating turbocharged motor...... and a lot of the horror stories from linering are due to poor installation techniques.

 

Bill - it needs linering as when one of my vavles decided to go exploring it scored the bore - will have to double check as i havent looked at it for a couple of years.

I was thinking of ebaying the 205 block off and just getting the 200 block from my mate.
