Hey guys,

another question re my engine build

I am building another small bore, and I wish to stay under 1200cc.

Its a shame the use of Hillman Imp pistons takes it to 1215cc.

What pistons can I use (mini or non mini) to achieve the maximum cc, but staying under 1200cc.

My block is sitting here waiting to go in to get bored/honed, just need to know what to.

Based on a quick calculation +0.100" should take a 1098 to 1185cc's. :wink:

<edit> I also recall GR having +0.100" pistons for 1098's

pure porn. thanks guys. before I call him, how much are they going to set me back? do they come with rings? who makes them?

I'm sure they come with rings in the price but as to what that is I don't know - they were included in the total price of the assembly. Best ask him. GR has them made to his specs in Tiawan. I had to wait nearly 2 years for them as his first shipment went 'missing' and as by world scale his order was a small one they put the re-run to the bottom of the pile :cry:

I think they are around $275 a set. GR pistons are made in Taiwan, (Hypatecs are too). These come with a Nippon ringset, they are good. Better than Hastings. :wink:

I'm sure he has them in stock - as part of the order went to MS in the UK and needs them for his own stock as well.

Haven't worked out compression yet - running 295 head hence the flat tops.

cheap. ill ring tomorrow to order my set.

thanks, once again for everyone's comments.

I was planning on using a 940 head, would the flat tops still work with the modifications to the block?

Yes.
But your C/R will be pretty high unless you enlarge the chambers heaps, stock they are only 21.4cc.

Post subject: 
hey doc.

thats fine, I was after a high c/r, and the head will be quite modified.

Ill keep you all posted.

he said I shouldnt be running a 940 head. stick to the 202 instead.

He has a lot in stock, so when I get back from my travels ill get the missus to get me some for Christmas.
