uhh no.. the H22's rev limit (redline) limitations are because of Stroke ratio's. The Stroke plays a large part in how high a engine can rev. Also 90.7mm is inefficient at high rpms, too high piston acceleration. It's tough to even get cams and head porting that will make the power up there. Thats why even after a good H22 build up, you rarely see a 9k redline on the h22. The stroke of a B18C is much better and therefore allows for a higher redline with fewer problems. In reality we dont need to rev that high anyway to make excellent power.

The leaning, I did have reversed. The H22 leans backwards and the B series leans forward.

The ringlands being weak are for FI applications. I kinda got ahead of myself. The stock ringlands can not hold the application of FI for very long.

The rest of my "opinions" are still true.
It costs much more to modify an H22 than it does a B series.
The biggest thing being, if we go forged pistons then we have to sleeve the block. B series do not have that drawback.

 

H22A buddy... especiallly when u have a prelude urself... u be smokin' a few cars with that engine.....

GSR motor is not made for the 'lude.... the only motor option you would have is the F22A, H23A, or H22A.... but jus save up for teh H22A.... its worth every penny.....

 

i second that.....

 

GSR vs Prelude h22 who wins. stock or with equal mods. doesnt matter

 

whats the redline on 4th and 5th gen preludes?

 

stock vs stock

GSR vs 5th gen = drivers race
GSR vs 4th gen vtec = 4th Gen win
ITR vs any H22 lude = ITR win

 

5th gen is h22a4 = 7500 limited at about 8000 depending on several ecu load factors (revlimit changes slightly)

4th gen f22a1 = 6200
4th gen h23a1 = 6500-6700
4th gen h22a1 = 7500 limited at about 8000, again it varies, cause ive had mine to 8200 on stock ecu on a clear cold night and sometimes on a hot day it will limit at 7200ish


ITR vs h22 lude is a damn good race tho, ive beatin a stock ITR
call it driver error or whatever you want but the h22a lude is in the same league as far as HP to weight

~boom

 

1/4 mi times from factory cut sheets:

5th Gen: 15.4
ITR: 15.3

someone find the stock 1/4 time for the GSR.

 

and if you believe those times, I have a bridge to sell you.

ITR: High - mid 14's
5th Gen: Mid to low 15's
4th gen: High 14's low 15's
GSR: mid 15's

 

i'verun 14.9's wiuth my all stock gsr so maybe your times arn't all correct and i've beaten lots of 5th gen's and have yet to lose to a 4th gen prelude
