i was just thinkin bout this. say you swap a integra engine into a civic, as well as 'teg ecu. wouldnt you then need to get rim/tire combo to match a 'teg original tire/combo circumfrence to keep the speedo same. i am assuming that the ecu calculates rotations by circumfrence, and time, and turns it into mph or kph, and then send that data to the speedometer. am i right here or missing something?

 

you could just adjust the speedo like a normal person.

 

or u could do nothing cuz if any the differences r very minimal if there is any, only time there would be an difference in ur speedo is goin big on ur rim/tire combo. like ridin on dubs. that would make a difference.

late

 

thats what i thought too.

 

Yeah the teg wheel sizes are almost the same as civic wheel sizes +/- 5%

 

I was going to say. Integra and Civics share the same ratio of tire sizes:

Civic 185/65x14" AND 195/55x15" (for the 99-00 Civic Si)
Integra 195/55x15"

 

I have the wheels and tires off a teg but like they said not neccessary. I think you are thinking too much.

 

if u dont have stock rims now with your ecu... why would you with a new ecu and engine... i went from 12-13' steelies to 17's and i think the speedometer was off by 3.2 miles or something

 

they make 12" steelies? wow......

teg and civ are basically the same circumference...

 

Wo! I thought my 13" steelies were bad!!
