More rotors, bearings, oil, water etc to take the beating = less stress
At those hp# i doubt anyone takes reliability into consideration

Simple rule, there's no replacement for displacement. Ask yourself this question, would you rather have 500 hp with a 5.7L engine or 500hp with a 2.4L? Which one do you think would be more durable in the long run and have more torque for better drive ability?

I actually hate replies like this. It's not too expensive provided your capable of doing some things yourself and you take the necessary time to properly research the conversion.

first, rx7 doesnt need a lot of torque coz it weighs so less

second, i couldnt find 1200whp but i did find http://www.catenet.net/graph.php?car...1&SUBMIT=GRAPH, in which there is an rx7 putting out 650whp which i think is pretty good coz it prolly runs 6-7 secs on a 1/4mile, im not sure about the fastest 20b but it cant be a lot better than that....n as far as the reliability goes....no1 cares about that if they are aiming for that high whp numbers...

also, wouldnt it be great if we can have sumthing like spoon or forged aluminum or titanium rotary block...jus imagin the possibilities.

650 isn't exactly 1200. It's not even close. And there is no way it runs a 6-7 second quarter mile. It says in the specs on the car it weighs 2600 pounds. Actually now that I think about it I shouldn't have even replied.

Kermit ran 9.9 at 650 hp, before the BIG turbo, at Calder Park in Melbourne.

It depends, which one is lighter, smaller/compact and cheaper and easir to rebuild?

It's size advantage would be no advantage if you over stress the smaller engine therefore causing more frequent rebuilds which in turn can be even more expensive.

20b = more torque, and quicker revving... Take a 500HP 13b car and a 500HP 20b car both with identical chassis and weight except for the 20b car being slightly heavier due to the engine. Do a pull from 40mph to 100mph I bet the 20b car will win every time.

Racing Beat makes aluminum side housings, so this is possible already. You will need deep pockets for them, but supposedly they don't wear at all. I may be using them in my next project.
