CGA3DE X-Alpha

Soo.. has anyone ever gotten a hold of this 101 ps engine? or know anything about what Nissan did to get those extra ponies out of it? I could guess myself on some different pistons and a cam change, but hard facts would be interesting.

I think the actual lump is the same but tubular manifold and larger body and lightly tinkered inlet are the differences

tubular mani, 10:1 c/r, a 236deg/8.3mm lift inlet cam and a milder than stock exhaust cam apparently

Yeah all pretty much along the lines of what I was thinking Frank, thanks though, no real reason to get one shipped here.
 
What's the normal c/r of a Micra engine?
Sounds like a big jump in power, for so relatively small changes.

9.5:1 for the 1.3 CGA3DE, which is a 1348cc giving it 85 PS.

The 1.3 CG13DE is 9.5:1 but only 1275 cc = 79 PS.

It's not really the compression ratio change that's doing all the work here, I'm blaming the cams and the exhaust manifold.

10:1 compression, improved manifold and cams with Intake: 236deg - 8.32mm lift, Exhaust: 214deg - 7.05mm lift.

Regular CGA3DE is the one I quoted stats for there.

But quite interesting with the assymetric intake/exhaust cams.
