Hi there, so my question is.. will everything be plug and play? even with the 00 si ecu? or do I have to do anything with the 00 si?

 

You need the p73 ecu

 

Why would you want to run a 1.6 liter less aggressive map on a 1.8 liter more aggressive engine? Not safe to do. You need the p73 ecu or convert to obd1, socket and chip a obd1 vtec ecu (or one that can be converted) and get a p73 map burned to it. Easier and most cost effective way, is to just buy a p73 ecu on ebay. There are plenty on there.

 

thanks for your input and yes i do have a a p73 ecu but i forgot to mention

if i were to smog can i just pop in the 00 si ecu or would it really be bad for the engine? (mostly using the si ecu for smog purpose )

 

What state?

 

California

 

Its possible, just for smogging only.

 

thanks for your input

 

Older engine in a newer car equals auto fail.

 

Very true

 

How would you set it up if you have both complete jdm itr and usdm si engine? I change my mind by going b16 bottom end with the jdm itr head

 

Don't waste your time with that setup.

 

You are in Cali, just leave it stock.

 

Don't bother. It will never pass.

I don't understand this or the last few posts.

Rock the original head with whatever bottom end.
Make everything 100% legit under the hood.

No smog tech will even ID the engine block/cylinder head unless your $#!T looks rices out under the hood. Ex.
Ditch the red valve cover.
Have correct evap with correct routing.
Nothing aftermarket under hood.
Remember it is a factory twin cam car that can fool even a tech semi-savy with Hondas.


If you can't do this^ then no Honda in California for you.
Cause it's not that hard.

I wouldn't trade our Cali smog laws for these rusted out hunks of **** I see in these other states.

 

Like the tech looks for this lol,

I understand this is the rule but duplicate the evap routing etc. and everything will work,
I do agree its probably over OP's head but sheesh, Cali isn't that hard to manage

 

I don't see how you can speak for every tech in all of California. Glad you got yours to pass but you cannot guarantee that for everyone.
