Avensis Engines?

[Hairibo]

Hi, I have a 2001 CDX 2.0vvt-i I love the car having the TTE springs and antiroll bars fitted. But its just a bit too heavy on the fuel. I'm getting 24mpg round town and an average of 31 if I'm really careful combined.

My question is whats the best over all engine avaible on the t22 avensis. 1998-2003 and is it possible to swap engines.

I know on vauxhalls its possible to just swap them over but I dont know much about toyotas. Would the 1.8 from a Celica GTI fit? can you put a D4d in.

I used to have a 1.8vvt-i and that was much better, with only a little less performance.

I don't know much about Avensis' (yet), but 24-30mpg from a 2.0 is very poor. You sure it is running right? Ignition timing would be a quick & easy place to start (if you have a strobe). Even my '96 2.0 Primera is better than that & I think it is bad on economy.

Is the final drive different for a 1.8 & 2.0?
