I wouldn't bother faffing around with creating some kind of 3ZZ hybrid
![](./images/smilies/spacer.gif)
(and I know there's a proper 3ZZ before anyone picks up on that
![](./images/smilies/spacer.gif)
), it's not a proven solution as the guys in the US will testify to.

Far better to leave the 2ZZ stock apart from some cryo'd lift bolts as they're a weak link, then stick a PFC or similar on and tune it for a reliable 200bhp-ish.

IIRC engine mounts will need altering along with a new manifold, ECU can be done but far better to just go PFC.

You won't want the 5-speed

'box as the ratios are all wrong for staying in lift, the 6-speed

'box is what you need.

You'll also need to make alterations to the wiring loom and the dipstick.
