Hi guys

 

Rebuild time, the car is goosed. One of the pistons decided to part company with the rod and has trashed the bore.

 

The garage are buying a used block but I was trying to safe some cash by sourcing pistons myself. Anyone know where I can get some forged standard sized pistons? I dont want to have the bores enlarged as this will mean more cash.

 

Many Thanks

YOu had better see if the block the garage buys has been rebored and then you can buy a suitably sized piston to fit?

near the bottom of the page..smithy does a rebuild kit if thats the route you are taking and doing the whole rebuild at once

Hi mate

 

I thought the rebuild kit came with 87.5mm pistons

looking at that you can go 87.5 or 88mm

but that would mean Ineed to get the bores drilled out wont it?

it would indeed.

 

and best you get it done or youl just be making a grenade.

Only if you have the 88mm ones, stock is 87mm, you would generally and should hone and deglaze the bores before fiting new pistons, hence 87.5mm ;)

so if somebody was to buy 88mm pistons what would the bore size have to be?

If you don't rebore so that the pistons fit the bores exactly then you're just asking for trouble!!!

If you bought 88mm pistons the block would have to be bored 88.010mm minimum and 88.020mm maximum. If you go above the max it would induce piston slap and then usually the piston skirt cracks / disintegrates.

Thanks all

 

Top advice, ill wait and see what the garage come up with and then buy the pistons etc.
