Get yourself a D23 and you'll be happy with pretty much everything in terms of drive-ability and responsiveness to modifications. If you're looking for 33+ mpg, looks elsewhere.

VEGAS i am not a fan of the sedan focus, but I LOVE my zx3, but I love the 2.3L in it... I have a 2.0L aswell, and both run great.. BUT I can spin the wheels just as easy with one and the other since the 2.0l is a manual, My automatic had a hard time spinning wheels until the 2.3L

UnbridledCarnage i had a d20 back in my 07 sedan days. it threw a rod at 24k. replacement engine ran fine for 60k til i finally decided the sedan just wasnt for me, sold it and picked up my zetec. i abuse my z20 on a daily basis and it just seems to want more. never had had a single issue with it

overall, i prefer my zetec. prolly cuz its the hatch ive always wanted and its an MTX (d20 was an auto)

matmatician One of my biggest regrets is not doing the 2.3 swap when my 2.0 Duratec dropped a valve. Apparently the previous owner didn't know that oil changes were required, not just suggested. My idiot mechanic I was using at the time said it wasn't possible.

VEGAS I bought a new 2.3L to replace my 2.0L and you need to do a few things to make sure you do not kill it, including the Valve Cover Vent, Get a Filter of Oil Catch Can.. 1" Spacers to raise the engine on passenger mount and a few other small things... but worth it when done,

You can use the 2.0L Computer but you will need a tune since it uses 15% more fule then 2.0L

with the 2.0L intake I know I am starving the motor but when I get the Cossy knock off intake and wide band o2, Balance Delete and Sump Baffle I am sure I will have a motor worthy of the upgrades.

I have much more lower end then before. but top end suffers I believe due to the 2.0L intake.

Wagone D23 = Wheelspin

2005zx4thewin the D20 isnt far from a D23, if you put the D23 head and intake manifold with the variable length runners you would see an improvement on the D20, and the D20 does has a timing chain, i have a D20 with 110,000 it has never used any oil and has never leaked any oil, never had any timing issues, dont get me wrong id kill for a D23 they are very hard to find and if you can get a D23 its worth the wait
