I currently have a h22a swapped eg hatch with a built head with blox b cams and supertech valves and a stock block with a 1 layer hg. The car just has a street tune of it thus far but we still need to work out a few more a/f and timing kinks. Well I just ran the car at IFO forthe 1st time and pulled 14.3 @99 out if 5 runs on street tires and using a m2s4.........which I didn't even bang 4th at all. The trans is way to slugish and falls on its face in 2nd and completely out of vtec and I am shifting at 8400rpm. I got a incar vid where I does that, I also missed 3rd but still managed to pull a 14.4@97, I will post the link. I currently also have a h2u5(cb7), a m2b4 and a jdm lsd atts m2u4. Ireally don't want to go h2b since I kinda got a gripe against bseries but I am really considering doing the mfactory 5.15 h series fd, the gearing and shift drops r top notch and seem to be inline with a 98+ 4.7fd itr trans.
I just really just wondering if anyone has ever used the 3rd gear from a longer ratioed trans like the h2u5 and used it in a shorter one like the m2b4 as 4th like how the dseries guys do with the cx 3rd annd use as 4th in si/dx/ex trannies which I have done before back in my dseries days. Let me know if it is at all possible

 

Swap in the m2b4 and call it a day. If you drive this car on the stret, the 5.15 in that trans may not ne worth it. If you drive on the street at all i would go with the 4.64. What size wheels are tires do you run?
