It definitely is the same pattern between the Z20NEx and the B207x

[Exmantaa]

The Eagle rods are lighter, and suports a lighter pin.(20mm instead of 23mm)Theyare also cheap. I think I need a custom piston either way, I cant find a high cr piston for the LSJ. When it comes to ecu, I have not decidet yet. There are a intersting project going on here: http://www.verboom.n...u/obdtuner.html It looks very prommising, but has no release-date yet.

you can get a 10:1 piston for the LSJ and then skim the head down by ~1mm to get up to 11:1

Anyone know if the crank trigger patter 60-2 for the Z20NET, as it's essntially the same engine as the b207, just a bit easier/cheaper to get hold of?

Diamond pistons go up to 10,5 CR (http://www.ottperfor...0L-LSJ-4p56.htm), or higher if requested. But indeed the 2,2's have a lighter pin, so maybe better for high rev NA.
And I know of that remapping development (I'm Dutch), but last time I asked this will not be cheap and not sure if it is suited for a high power/rev NA that probably has some ITB's fitted... (The US LSJ ecu's can be remapped with the HP Tuners tool, also 60-2 trigger.)

But just curious; why not using a good old XE lump in there? Lots of available stuff around and bolts right in with Turbo mounts...
