I already did a search for this but on hp.com (when it was up) there was a guy by the name of Brady, and he had this webpage with a bunch of free mods you could do to the h23a. i now have a JDM h22a and i'm looking for that link or anyinput if those mods work. some included EGR mod, coolant bypass, and some other stuff i cant think of off the top of my head.

Thats the page i was looking for THANKS! anyone actually do these? I'm looking into doing a few. How were the directions and what was the outcome, harmful or actually help produce power?

I have my timing advanced some. I don't notice any difference with the intake runner one.

j92s · 10-01-2002, 11:23 AM

I did coolant bypass, ignition advance, valve cover thingy, and maybe another, i dont reember. I also lost about 100lbs of other stuff. Made a very noticable difference. Im gonna take it to the track next time its not raining just to see.

i did them all and found out that i didnt like the intake runner one, and i only do the coolant bypass mod at the track because it messes up your idle. Id do the EGR one but it seems like a lot of work.

Thanks for the input guys....anyone else?

does that flapper valve actually work?

vile10 · 10-01-2002, 05:03 PM

my friend who drives a 4th gen lude said he did them all and didn't like them and change it back, only left w/ advance timing

concLude · 10-01-2002, 09:00 PM

so far it sounds like advancing the timeing is the only one that wont mess up your idle

red92si · 10-01-2002, 09:45 PM

I advanced my timing by about 2 degrees, and I can feel a little extra pull. I havent tried any other of the mods.

remove your p/s belt, best free mod ever

ignition advance is good also

i have the parts for the EGR block off but haven't done it yet, i will report after i have done it

I haven't noticed any difference in my fuel economy! I like the little pull that I do notice.

is the timing mod just a free was instead of advancing the ignition electronically with an aftermarket ignistion?

LudedudeSi · 10-02-2002, 01:22 PM

You can advance the timing with the Distributor. I know it doesn't work on all Preludes and I am drawing a blanks as to which one. I know some people that had theirs advanced to 19 but I have mine set at 17.

FPR mode gives you a bit more power top end, and it probably comes sooner than ususal. Low end, it'll be louder (all 8 runners will be open), and there's a minimal power loss.

It's good for the track but not for every day driving.
