Im looking for suggestions to slightly tweak a H22.

I dont want to go wild or spend big $$

Im just looking for a good daily driven motor that idles good and will be reliable.

So should I add a header, CAI or ......

I would be interested in any tricks like the TB coolant bypass too.

Thanks!

 

The standard I/H/E combined with a light weight flywheel and great street clutch
on top of that if you still want more power add a VAFC to tune everything out and then buy some great valve train work such as JUN, Crowers or Peak head kits....
this is my suggestions is I have these mods myself you would a very very fast Vtec street car and it would be all motor and very reliable ----

 

Regular hot air intake as its called, (bang for the buck) hotshot header, 2.5 exhaust piping and a muffler and a 70mm tb. Not to much $$$ involved and it helps.

 

if u want something mild, just get a nice 3" CAI, and 2.5" exhaust piping and muffler. I'd personally skip the header and 70mm TB. Not many headers out there in a reasonable price range that have proven nice gains. And the ones that give you decent gains are like 1000 bucks, , but if you wanna squeeze every last hp out, then even a cheap dc sports should help ya a bit.

as far as the 70mm tb, i doubt your gonna see any gains, i've dynoed a 64mm, against a stock 60mm, and saw no gains on back to back runs.

lastly invest in a VAFC or some sort, and have it dyno tuned, that will be your best mod out of the whole list.

 

I'd just go w/ Short Ram, headers, chipped ecu (P28 maybe), catback exhaust, clutch stage 1. That's pretty much my setup and it's fast.
Go a step furtehr and get Stage1 Cams w/ Type S Pistons and tune it on a dyno.
That's my next goal.

Forget eveything I just said, don't copy, do what you like.... heh...

 

What does a lightened flywheel do for the motor?
What brand and weight would you recommend?


Will it lose torque going to 2.5" piping?
What about the cat? I have to do something about that anyway...can you just remove that alltogether or would that mess something up?


I dont know much about a VAFC. Is that Hondata or something else?

and a single stage euro accord manifold and a chipped or uberdata tuned p28

would be nice.

 

What exactly is big bux ?

Here is an example for you, Stock h22 motor with, intake, hotshot header, 2.5 in pipeing with a 5zigen exhaust, str 70 mm tb, stock lighten flywheel, fuel presure regulator,vafc not tuned with vtec at 5400 rpm, chiped p28 ecu in a civic ex coupe with bfg drags hit a 13.6 all day. This setup did not cost much

 

all stock full options 95 prelude with nt555R's 14.1 all day

 

Not big money is less than $1500

I dont really think the H22 is worth dumping that much money into....I mean I dont really expect my Accord to be much faster than the F22b2 I have now except for the auto to manual swap im going to do which will make more efficient power out of what Im getting.
I could be wrong though, which would be a great suprise, but Im not expecting much.

Keep the suggestions coming...Im doing searches on what your suggesting to get more info.

Thanks guys

 

with that p28 it couldve used a single stage IM.

 

oh yah and I always take out the secondaries when using a p28

 

Jun cams would be great for you
