h23 IM and delta 272

[91project]

just wondering what gains could i expect putting on a h23 IM with the delta 272 cam also?

i have the f22a1 with short ram and headers and exhaust.

That would give you some good gains along w/ a P12 ECU since you've got the A1 engine. Its used in the Preludes w/ the F22A1 and in that version it makes 135hp vs only 125hp in our CB7s.

instead of using the p12 I would get a po6 chipped and tuned for maxima performance of the bolts ons and it would give you the best gas mileage. You can port out the h23 im while your at it. If you get a str8 pipe 2 1/8 you will probably gain about 20-30 hp but I don't know how much to the wheels

Correct me if im wrong, but the h23 intake mani has secondaries on the IM which the p12 ecu can't control, p12 controls only 1

My car ran that setup along with an intake, header, exhaust, and nitrous for a while. It was a good feeling and the car sounded good, and it was definitely an improvement over stock. Also, I too recommend going with a chipped po6 and getting a tune, as the cam is much more aggressive and combined with the h23 IM, you will see more airflow up top.

Also, please note that some people have had idle issues with the 272 whereas I never did. Some people were unable to get their car to idle on a non chipped ecu with the cam, so you may want to take this into consideration and seriously consider the ecu option in addition to these mods. Car will sound great though, that is for sure.

Yes it has secondaries, and yes the P12 can't operate the butterfly valves to open them. But just remove the butterflies from the IAB plate and call it a day.

To the OP, I have a Bisi Level 2 cam, H23 manifold, and the standard bolt ons, and it's feels really good. I am running a PT6 ECU as of right now and am planning on getting a chipped P06 and a tune this spring/summer (or as soon as $$$ allows me).

Just my 2 cents yo, connect the IAB to vaccum, it will only open it you give full throttle, people think i have a mean vtech engine lol and sounds great when you pop it

thanks guys i did this whole setup over the last few days took me a couple days of down time because i needed cam seals valve cover gaskets and egr gaskets and im gaskets and all and i also replaced my vacuum lines and 5/16 fuel lines and the parts store had random hours during the new years but tommorow morning it should be done.

as of right now it does have some idle problems as it feels like it is not getting enough gas when idleing but i did remove the butterflies from the iab plate and also have the p12 ecu.....so what tune do u guys reccommend to with the p06 ecu? because i deff feel the idle issues with the p12

I guess theres more than one way you could go about getting it tuned. In my opinion because its not anything built I would just get it chipped. Chrome is a popular program but there's many to choose from. There's a guy on this forum that does it. Look him up I think it MRX I don't know what program he uses but hit him up

mrx hasnt been around lately. hes been busy. d112crzy from crzy_performance is the one you want to talk to. check the members shops.

but yes, a chipped and tuned ecu is best when you have a wild cam. a p12 with the butterflies hooked to vac or removed will work, but wont be optimal. same with a p06 to operate the butterflies. youll probably run rich with those.

[91project]

thanks how much does just a chip run me for a p06?

[91project]

nvm sorry found it

finished it up today and the car seems like it is running real rich and since my car is auto whenever i put it into neutral it seems like it isent getting enough fuel and stalls if i dont give it some gas. i have the p12 hooked up now but im now talking to the guys from crzy.tuning to get a basemap setup for what im running. i aslo had a CEL for a lil it was code 43 the 02 sensor...what could have caused that? but now i went on a trip to test it out and drove for like 40 miles with no cel now so idk what that was all about.

the chip is not what you have to worry about. its the actual tune that costs, and requires some extensive knowledge and tools.

everyone thinks that they can just slap a chip in and have a 'tuned' car. i blame ebay.

Did you put in the 272 cam? If so, you may or may not have idle issues, as I said. Some of us like myself had no trouble, and some others like hondafan81 did.
