vtec controller for FD1

[aaronng]

I guess it would. I've read a bit here and there about the Hondata reflash, but iuno whether or not it works for the K20Z2.

This will mess up your warranty tho, and cost a lot, and also increase the redline

Won't work since Hondata US made a reflash only for the base RSX, not the Civic. Even that reflash doesn't alter vtec point and doesn't increase the redline.

I didn't think of looking on their site!

ECU must be sent to Hondata in order to be re-flashed with the updated program. Hondata does not sell direct - all sales and payment must be conducted through Hondata dealers. The upgrade information form must be sent with your ECU.

looks like we've got a lame, unreflashable K20

curious/stupid question: what makes the K20z2 different from the K20z3? can it be easily changed?

The K20Z3 is the one used in the DC5 Type S. So you get proper VTEC head and lightweight components in the block, plus your usually high RPM intake manifold and exhaust headers. Also, that runs 95 RON minimum instead of the 91 RON that the K20Z2 requires. If you want to change it, do an engine swap. But you'll have to research on your ECU options.

so is the block the same size with the 20z2? could you get someone to modify the engine with the components of the other, or are there too many parts and missing parts on the block for this to happen?

Costs more to swap components. You're better off replacing the whole engine. Downside is you have to register the new engine with the motor registry.
