Buy a MIG welder you will need it and read torquecentral.com
I've been keeping up on Torque Central for some time now. I'm going to get started on the swap within the next 6 months.

This is true if you look at it from a conventional way of thinking. But Porsche would not have such a winning race history if was of conventional thinking... as with Mazda. Give the rotory engineering time to develop.
tbielobockie, is any of this sinking into that granite skull?

Who cares what he thinks. If you love your RX-7 you will work on it . . . I personally like the LS1 T56 swap idea but also like a supercharged Renesis swap . . . or just a supercharger on the REW instead of the turbos. I don't know why but I don't like turbos for some reason.

I recently went to Brian Hinson's partner's shop to buy some FD parts.. there I saw his V8 LS1 conversion in progress.. I have to say.. Its pretty nice.. Nice, Clean, and well designed.. But I don't know.. I like the 7 because its simple.. Have any one looked inside of the rotary engine?? I think if you took disassembled rotary engine and piston engine, place it side by side and someone asked to put it together... I would be picking rotary.. less parts!!

But seriously.. I would of never came to the forum if my FD was reliable.. The whole fun of these cars and close niche of people I acquired IS thru because of the uniqueness of rotary engine.. I didn't buy this car because I wanted muscle car.. I bought it because I was curious.. I knew about the reliability issues.. thats why I bought a second engine already.. KEEP the ROTARY ALIVE>> DON'T PUT PISTON>>

Have you??

1 eccentric shaft
2 stationary gears
2 rotor housings
2 end plates
1 intermediate plate
1 front cover
Oil pump and drive chain
2 rotors
6 apex seals, in 2 or 3 parts per seal
6 or 12 apex seal springs, depending on apex seal design
12 corner seals, 2 pieces each
12 corner seal springs
12 side seals
12 side seal springs
8 oil control seals
8 oil control seal springs
8 water jacket O-rings
etc.

Being fairly conservative, that's 120+ parts, and that's just the "short block" of a 2-rotor engine, not including the oil pump pick-up or pan, or the 17 bolts holding the whole rotary sandwich together.

Typical V8 short block...

1 block
1 crankshaft
5 main bearings, 2 pieces each
5 main caps
8 connecting rods
8 connecting rod bearings, 2 pieces each
8 pistons
24 piston oil control rings
8 wrist pins
1 cam
5 cam bearings, 2 pieces each
1 timing set
1 front cover

94 pieces, not including the oil pump, pick-up, or pan. Even if you include the 10 main cap bolts, that's 104. Make it 4-bolt mains and include the rod cap bolts, and that's 126 parts if you want to be picky.

A 2-rotor engine may only have 3 major rotating parts, but don't be fooled into believing that they're not complex internally. There's a huge number of parts they rely on to keep combustion, oil, and coolant out of the wrong places, and sometimes, those parts fall down on the job.
