I recently built a 2az that went into a Scion tC here in America. I used JE 11:1 pistons +.5mm, k1 rods, brian crower valve springs and retainers, brain crower stg 3 cams, some crap raceland header, an OE crank from a 100k mile camry, a stock intake and a 70mm rx-8 dbw throttle body that makes 238whp NA and 463whp on a direct port nitrous setup. It was bored without a torque plate, it's balance shafts are removed and plugged and it didn't need any balancing and so far it's been through several bottles and approaching 25,000 miles on the rebuild. It's not sleeved or any of that bit. It runs off the stock ECU with an AEM F/IC and a camcon VVT-i controller. Stock fuel injectors with a big fuel pump to support the nitrous setup's fuel injectors(mechanical nitrous injectors, not a second EFI rail). I built the thing in my basement for christ sakes. It's like the chevy 350 of four cylinders I've found. It's easy to build(although not so cheap) and can take a ton of abuse. I have a few pics and such of the build if you are interested.
ANYWAY I was interested in how your coupling your transmission to the engine. What parts and configuration do I need to bolt up a rwd trans to this engine?
