Is A20 carbed engine and EFi engines totaly the same exept for exhaust and intake???

I've just blown my efi engine, and can get a carbed very cheap... So I want to take this engine and install my exhaust and efi intake...

I'm sure this is written somewhere in the faq, but I'm running out of time, so please answer quick....

The carb motor will work, but you'll have a little less compression...

swap over the efi cam into the carb head.... but try to swap over the entire efi head if it's still good.

after that it's just a matter of bolting up the trans, exhaust manifold, and intake manifold.

but anyways I'll give you some pics to help you swap over the other smaller components to go from carb back to efi.

thanks, and yes the efi head is still nice, I have blown some valves and a piston...

So engine is the same, except for the cam?

No, the pistons are different also. They are what raises the compression in the A20A3 compared to the carb engine.

with the cam you have more power then the stock carb engine but less power then the stock efi engine...

but at least your car will work again...

what did you want pics of?
I have shots of the EFI thermostat you'll need to swap onto the carb motor... if you decide to use the carb head with the EFI cam, I can show you the distributor bracket / outer cam bearing that will need to be swapped from the EFI head over to the Carb head. The water pipe is different but I don't have a clear shot of that.

I gonna put it in like it is with my old efi header and exhaust, not change cam...

I'm gonna put a B20a engine in when I'm done with the military and thats 8 months too....

I just want my car to run for now...
