That would be awsome. Front spacing wont be that much of a problem. A V8 is just a 4cyl split down the middle. Not that much longer, just wider. The straigt six would be a bastard. May have to use a thin electric fan or somthing.

The ECU wont be that hard either so long has you have a complete engine harness. You can mount the box anywhere (without heat). I don't even think the 4.7l even has a carby version! And anyway I am a huge fan of injection.

That is a very big problem. You could fab up an oil pan to get more room but I am not sure that will solve the problem. The engine is just bigger. You could use your original cradle idea to mount the engine above the front crossmember but then I am not sure if the trany would fit down the drive tunnel. Besides you want the engine to be as low in the car as possible for balance.

I wouldn't recomend the 'crazy cable system'. If a cable ever snapped you would be on the road to nowhere fast without a driver!

The only thing I can think of is to replace the front x-member with something that will allow you to mount the engine and rack lower. That would not be an easy fab job though. The control arms hook to the x-member. So it has to be very, very stong, especialy at the bushing mounts.

I don't think it will get in the way of the intake. That is all on top of the engine. A rocker cover maybe. You'd have to take some measurments. All I can say is relocating the booster would be a huge PITA to move.

You wont be able to move the engine back that far. Move it more that 4 or so inches back you you'll have a rocker cover/exhaust header in your lap. I like the idea of balancing it with a sound system, LOL! The frightning part is that it would actualy work. Throw 3 or 4, 12"s in the back and the weight will be 50/50. If heavy.

Nope the more the merrier. This is (basicaly) an unmoderated list. You can post what you want, as much as you want, any time you want. The only thing I wouldn't tollerate is spam. (For anyone reading selling celica parts and stuff is okay. Get rich quick and porn is not!) However because my foum page is so thin it might be a good idea to start a new thread.

---- so I did :-) ----

Here are a couple image of the engine I found on the internet.
