cg10/13 combination

[tomwest]

i have a number of questions relating to these engines!

1) will cg10 con-rods fit on a cg13 crankshaft?
2) will the capacity of the engine increase or decrease fitting cg10 rods and pistons in a cg13
3) will the compression ration increase or decrese with same above.

failing these!

4) best DIY method of getting gudgeon pins out

Wont fitting the rods lower the cc? I thought you just fitted the pistons as the crowns are different and up the CR or something like that

they,ll fit, but there,s about 15mm diffence in length tom

 

[tomwest]

if the rods are shorter it will increase the capacity and decrease the CR. maybe a good idea if you wanna push big boost.

i presume Frank means the 1.3 rods are 15ish mm longer. i guess there'll be clearance issues on the head, and it wont go.

its going to be a case of switching the pistons over. goody.... :|

its the 1.0 rods that are longer tom, so the pistons would stick out the block 15mm lol (and the rings would jump out ) but they would,nt change the cc tho

I have a set of cg13 rods with cg10 pistons on them with new piston rings fitted? And a 1mm skimmed head (selling without buckets/shims/cams as they were sold)

Is my understanding correct Frank, that doing it with a CG10 block, using the CG13 crank and rods - (longer throw of crank, with shorter rods - to keep TDC the same) with the CG10 pistons with give a high compression 1.3. Which then re-assembles as it was before with the original head etc which will want 1.3 cams fitting.

 

[Stani1029]

Mark all you need is a cg13 and 1.0ltr pistons, just a case of swapping pistons over

 

[whipit]

Yes to all the above but you don't have to fit 1.3, rods, crank and cams to a 1.0... you can just fit 1.0 pistons in a 1.3 block.

stani: interested in any swop bits? i want the pistons on the rods, as its so much easier than pressing gudgeon pins out. would be happy to swop for a number of parts off the list.
