You'd only need more fuel if you can get more air in.

The current problem with putting on a Corolla TB on the 1NZ intake manifold is the opening on the manifold is only as big as the stock TB. So IMO, it's a total waste unless you bore out the manifold to match the larger TB. It's like putting a restrictor plate the size of the stock TB without it being matched.

it's wider than the 1nzfe motor, so the end ports would pass the motor block. I was covering up those sections with JB weld but never got around to installing it since my 1zz throttle body had broken sensors and wasn't working. Till I find some money for another throttle body, it remains stored away for a rainy day.

I forgot you did this a while ago, right? I think you posted it up on Echodrivers.com. I think with a new intake flange you could make it work right.
