anyone here have there h22 turned into a h25 by stroking there block? just trying to get a feel for what people are making NA and Turbo wise!... i wanna see the ideal hp/tq made from a fully built NA motor and fully built turbo motor if possible... thanks guys. tried searching but threads are all old school with no dynos or anything just talk about f the kit and do h23 crank and blah.
thanks again

 

i know john went to about 2.4L with his build a few years ago.

F the kit and do an H23 crank.....BLAH!
You can also look into having the crank offset ground like 2point6 did.
Natalie(blacktraxgirl) from BTP is making 270whp with a 90mm crank!
NAh2b is making 300whp with a 95mm crank!

So ummm, yeah F the Crank....and anything from Crower for that matter.

 

lol thanks for that... whats wrong with crower?

 

wow very interesting. lol but not to sure on the IM kind huge. lol but overall looks sick

 

They never took the import world seriously and never made anything worthwhile for us......
Their cams suck, strokers are overpriced........Valvetrain and Rods seem to be OK, but what can I say, I have a chip on my shoulder about them and their BS customer service.

Birdmans IM was sick for sure.....I think it was overkill as well.......but who knows.

 

yeah no doubt their service is BS... dont care for their valvetrain i prefer skunk just like them better for some reason..

the intake was overkill but damn i bet that **** gets *****! lol excuse my french

 

That IM provided a very sick redline of 8500rpm IIRC.

 

WOW!!! did it gain power the whole way through or lost some like at 8k or so?? if it gained power all the way through thats truly AMAZING

 

IIRC it carried all the way after a 7000+ peak.....
Awesome, but not TOO amazing.....With the BTP3 when I 1st tuned it, peaked at 7200 and carried flat until just over 8000 before it slightly tapered off with only a 5-7whp loss by 8300rpm.

 

ok thats not so AMAZING anymore... lol thats good though both ways... i thought it carried it all the way to the end. man did i fool myself

 

It did carry all the way.....but it flatlined. Which is awesome!
Take a look at some stock H22 dynos and you'll see what I mean.
This is mine from when I originally tuned it. We let off at 8200, there's no telling how much further it would've carried had we kept going......maybe 8400-8500 without losing more than a few HP.
This is a stock JDM H22A with $500 header.
RED=S2S1 cams
BLUE=JUN cams+BTP3 IM

 

wow thats pretty good considering it was on a dynojet with the absence of all the other variables on a dyno jet... i give you props my man. which header was on it? thats with vtec hitting too right?
