1.0l pistons and rings

[wehey]

Ok. I have just secured a 1.3 engine that I would like to fit some 1.0 pistons to.

Where's the best place to source some from?
Could I get away with second hand pistons and new rings to keep costs down?

thats what i'm doing..... the trouble is getting the gudgeon pins out without damaging the pistons.....

but also putting new head gasket, new head bolts etc.

Many have to rethink this idea

someone might offer you some 1.0 pistons already fitted to 1.3 rods tho eh http://www.micra.org.uk/threads/wanted-k11-1-0l-pistons.61077/
or failing that, i have some timing chain half links if you want to go for a 2.5mm headskim

That would definitely save the day
It would be great to add these pistons whist I have the engine sitting there as an engine swap is a bit of a daunting task for me and I don't want to regret not doing it at a later date.

(Still can't get into that part of the forum to see your reply Frank)

Also...could I use the 1.3 piston rings on the the 1.0 pistons as a new set are £100+

yes, coilpack (post 2000) rings are different tho

 

[tomwest]

can get piston rings for £55 on ebay. not sure on quality though! Frank, do you still have a tool for the job?

we tried various unbranded ring sets on the kart engines tom, and they wore out within weeks, and yes
and here is the half link for a 2.5mm headskim

sorry frank, i meant a tool for the gudgeon pins. i thought you had a cylinder the piston sat in so you dont damage it pushing the pin out. awesome halflink by the way!

those piston rings seem to have disappeared from ebay!!! although its a while since i looked for them.

yes we still have the tools tom, oval skirted coilpack and pre c/p

 

[wehey]

They look like instruments of torture !

 

[tomwest]

i definitely need to use/borrow/rent these at some point. ive been talking about doing the piston swop for well over a year now!

still considering new big end bearings, but have a block, new head gasket and bolts etc.....

how happy are the gudgeon pins after theyve been pushed out? i guess they still look pretty perfect!

 

[frank]

the pins come out unmarked tom, and you can re-insert them cold, you have to heat the rods to 200deg+ to get the pins to initially move when removing tho

 

[tomwest]

yeah i thought as much! bang the rods in the oven for an hour or so then! would it be possible for me to head down to you at some point to use the tool?

 

[frank]

i usually hold them over the gas ring for a couple of minutes tom, and np
