im looking to build up a naturally aspirated 1nzfe for my yaris and im wondering if i can get some help.

does anyone make high compression pistons for the 1nzfe? ive searched before but i havent found anything. i remember seeing in a mag somewhere (maybe siphon?) about and echo/vitz hatch built up w/ all sorts of stuff, but i only ever see low-comp pistons and etc.

also, where else should i turn for other internal parts for the 1nzfe? valve springs? connecting rods?

what about engine management? what works well for the 1nz? anything stand-alone?

what about the weapon R intake manifold? is that a go or a dud like the richard holdener manifold...?

thanks for any info you can lend!

 

or cams...?
