holy **** this is confusing me....lol

im going to be ordering an itr swap in a couple weeks, and i need some info, any help would be greatly appreciated

so, i know there is a difference between the 96-97 and the 98-01 engines (200hp vs. 210hp)

but what i really need to know is, what are the differences between the 98-99 and the 00-01 itr engines, if there is any.

and i also need to know the difference between the 98-99 (p73-013) and the 00-01 (p73-023) ecu, if there is any.

again, any help would be greatly appreciated, im just trying to find the best choice for me

 

from this post... https://honda-tech.com/forums/acura-integra-type-r-8/count-ing-itr-ecus-p73-2067011/
P73-003 - 96/97
P73-013 - 98/99
P73-023 - 00/01
all JDM P73s are OBD2a

none of them will pass an emissions test, none are scanable with an OBD2 scan tool.
As far as performance difference, (I have all three) zero difference on the dyno between the 013 and 023 when I ran them back to back.

What are you concerned about?

 

No need, too late, ^^ got what you needed.

Good luck...

 

im mostly concerned about getting the most powerful itr engine

 

so i can go with a 98-99 or a 00-01 itr engine/ecu and there wont be any differences?

 

hp and power is the same 96-01. however, if you can get an 01 you'll have 5 years newer on all the seals. might be 1-2hp of difference in the early 96 and 97+ since the late 96 early 97 jdm itr began hand porting and later went to cnc. the header is also different. torque curve is also better on the 98+ but only slightly. you can watch the test over in jdm land where they race the 96 and 98. 1/4 mile was identical

 

i thought 96-87 itr was 200hp and 98-01 itr was 210? ive read this many places...

 

cant wait to see this motor in your hatch chris!

 

an OEM ECU will never put out as much power as a well tuned ECU.
but, the quality of the tuning is key.

to me the newer and less mileage the better. as idrivesideways said, newer means less chance of sealing issues and part failures due to age.

 

I thought the cams, throttle body, and header differed between 96-97 and 98-01.

 

let me start with first being helpfull,

go to http://www.isitaboat.co.uk/cars/hond..._type_r__ek9_/ and view the b-series engines specs you will notice the cams on the 96 being much more aggresive when compared to the 98, thats one difference,then you ask your self well hey why does the 98 show as 210hp or atleast the same 200hp on other sites when a 96 makes 200 hp with more aggresive cams?shouldnt it be the stronger one?

well the as relic said it the 01 and 00 do infact have the same ecu maps as the 98 and 99 obviously because the transition was done at 98 therefore the differences are between the 96-97 vs the +98 alltogether

so the reason why the +98 makes just as good hp as the 96 is because the 98 tune is set more aggresively,the header is better,better porting and by doing all that the 98 gets the same peak power but with a linear powerband and better tq curve.

BTW Iam not sure how it is for usdm or jdm but I always thought a 96-97 meant obd2a and a +98 meant obd2b for honda,atleast thats how it is here for us edm owners and we easily pass both emissions and have obd reader work for us!

I was wondering what the results were if relic compared the same motor using the 96 ecu vs the 98 or 00?

 

The site you listed is incorrect. All of the ITR and CTR B-series engines shared the same exhaust cam for starters. Their data is jumbled and lists the GSR cams for the 98 spec ITR. The 98 spec engine has a longer duration intake cam compared to the 96 spec.
