Been wondering--are thar any better pistons for the 90's??

I know about boring out to 90.5 and rebushing the rods and such---but ...is this all there is???

OK DUCKING for cover now under my newly blasted teener (IMG:http://www.914world.com/bbs2/html/emoticons/hide.gif)

I have a 24mm pinned 90mm piston design, but its a JE and cost 800 bucks a set.... Actually I am going to try a 90mm bored, 82mm stroked engine with a set of 1.7 Q heads as a base. I am looking for ultra port velocity and ultimate cylinder filling with a dose of compression. I think I can make 150 torque filled ponies with it with the right cam... I am profiling one for it over the weekend...

So, 90x82 is, uhh, (carry the two) about 2085cc, or a tad bigger than a 96x71 2056, which uses off the shelf parts. Yet I've never seen a 2056 make more than 120hp or thereabouts w/o an unstreetable cam. I've seen non-Type 4s make 150hp out of 2 liters with a streetable cam, though (twincam Alfa, for example).

Stroke really makes that much difference?
