CG10 crank in a CG13

[CMF_Nissanmania]

Planning a CG13 engine build and thinking of the possibility of destroking it with a CG10 crank and running a turbo. This will keep me in the under 2 litre class for competition (using the CAMS 1.7 multiplication factor). Plan to date was to stick to NA but the small exhaust valves are a bit limiting to outright horsepower.

My Haynes manual indicates the blocks etc are identical other than a longer stroke in the CG13 giving the bigger capacity.

Anyone done this before?

Any ideas on how to source a CG10 crank?

The pistons are also different I think, the 1.0 having bowls in them, dont think the 1.3s have them.

I have a 1.0 in my back yard in bits, not sure what the condition of the crank is but perhaps I could have a look later on in the week.

Will be organising new pistons so not an issue.

A second-hand CG10 crank in good condition is all I need at this stage.

the 1.0 pistons are flat the 1.3 dished. so 1.0 pistons are good for na high compression.

Thanks Nismomicra. Postage to Australia might be costly for a heavy lump of metal but let me know how much this would cost. I've still yet to confirm whether my engine builder is going down this road etc so I'll get back to you if I want to proceed.

Thanks. No big rush at this stage as I'm still trying to decide which way to go. The eternal car performance question - turbo or NA!
