High Comp CG13DE

Okay, so I got a spare CG13 engine in the garage, ran like a dream before I took it out so I may swell make use of it!

Was Planning on a low budget project, so I thought why not make it high compression!

Iv looked around for thinner gaskets and iv found some at 0.5mm thick, for about £200 in japan!
this is way over my budget, but the 0.7 mm reduction in the gasket thickness over the standard gasket raises the compression ratio from 9.5 to 10.3

so if i was to skim the head by 1mm then I should be getting a CR of about 10.45, got this from a calculator and data from another thread on here (can't remember where!)

Also roughly how high of a compression ratio you think I can go before it will start pinging using regular petrol and V-power?

thanks!
 
Just gunna revive this to save on new thread.

Search is useless on this app!

What skim can I do with cg10 Pistons in a cg13

Any other n/a mods worth doing?

I have a starlet inlet mani, what's best size t/b to use

......which injectors?
