hi there ppl i have a 200 block cosworth engine that needs boring i was wondering what pistons i would need after it had been bored or what choices would i have thanks

 

are you joking?

depends on how much is bored out! - what size is it at the moment?

or is this a trick question?

 

i was told it needs borein as it has a bit of a lip at the top ot the bore or does it just need re honeing its a standard engine just needing a rebuild .i dont now much bout boreing ect and if ya can do it with these engines info would be much apriciated thanks

 

boreing is basically makeing the holes where the pistons go bigger - so the piston size will depend on how bad the bores are and how much is bored out

unless you are going for silly power; standard mahle pistons will be enough

edit to say: if its just a lip, you could probably get away with a hone - best off taking it to someone who knows what they are talking about IMO

 

is there anywhere i can get it checked over in birmingham thanks for the help mate

 

if you want it checked and built for you; take it to Reyland

if you just want the machining work done; take it to a company called halesowen engines

 

i now relyland but i aint got that sort off muni to spend ya see .i heard alot about the haslowen engines cool ill go see em .im trying to save as much cash as i can buy doing it myself ya see iv done a bottom end bearings be4 but never changed pistons an such.

 

how much would a rebore cost me

 

all depends on who you use; but i'd expect between Ł80-Ł120

 

No point just honing the bores and fitting new std size pistons (if thats what they are at the moment) as bores wear oval from front to back, go for +0.5mm and you will be just fine.

I can get the block bored with torque plate for Ł100 cash but you would need the pistons also to determine the bore size prior to maching. Based near Birmingham

 

pm me with some details where you are i might pop up the weekend if i can get away from crimbo shopping lol

 

Mate I was running my car on a pretty tight budget and Martin's sorted me twice for VERY sensible cash. Go and speak to him.

Why dont you ask Martin for some advise on what you need or want im sure for the price of a Bacon butty he at least talk to you and you could gain a wealth of information and save a penny or two aswell.
