PS: I get 32-33mpg in the city with the AC on and while burning 87 octane. I'm not light on the gas pedal, either. I spend a lot of time on the WOT fuel map. I haven't yet taken this thing out of town since I put it back together, but I'm expecting to get in excess of 43mpg out of it since the highway's speed limit is under 2k rpms. It's crazy, who knows. I'm probably taking it to the beach next weekend, so we'll see.
I can't post whether or not it's any better or worse than what the CX engine would do with it because the cx engine I replaced was worn out really bad. I get about 5mpg more than I used to, and my car is much faster (2 seconds in the 1/4). Most of that, I'd attribute to having a 0-mile engine with 8 extra valves vs. the 100k old oil-burning no-compression-having D15B8 that was in it. It's only been swapped like this for about 1500 miles, though. Barely broken in.
The torque curve is so different that (you're right) it is really wierd. A CX makes all it's power down low, a DX makes it up high. I'm sure the hx/dx tranny deal is the same on your car. Slightly over-do it and you'll blow the tires off. Barely under-rev it, and you bog. It can be a dog off the line unless you feather the clutch just right, and it's really touchy. 3rd always bogs because the torque curve of a D15B7 begins higher than the revs where you shift into it. suxors. 1&2 are evil, though. :rick:
And I'm 31... I beat the hell out of cars. Worse now than when I was 20. :driving:

haha you're my inspiration, i hope i'm still killin honda trannys right and left when i'm 31 :thumbup:
But you're right 1st and 2nd are pretty sick, it just shoots up when the boost spikes to 10 pounds in first. Third isn't really that bad for me, i have plenty of low end torque (around 150 wtq at anytime above 3000 rpms) to pull the car but by the time i hit top of 3rd i'm going freaking 110 about to slam into the governor.
Hrmm...i wonder what the car would pull to in 4th gear without a governor. When i had the 5th gen SI tranny and the fields SFC which killed the governor in there it went to 135 easily in 5th and had plenty more pull before i let off.

haha i don't know where that extra 30 pounds of torque came from i swear
BTW how much did it cost for your pistons/rods/install? Did you go ahead and sleeve it also? I'm about to upgrade to precision SC44/inline pro manifold as soon as i sell my APEX kit, time for some crazy #'s.

I didn't know that InlinePro made D-series manifolds...thats awesome. What kinda od trubo is that precision sc44, is that like a custom T3/T4 or something?
i went to precisions website and they don't really list, they said something abou a T4 exhaust side or something, that pretty nuts...

...at least mine won't. 125mph in a 2000lb FWD with drum brakes (and H-rated tires) is not for me. :nervous: I'll save that for RWD and AWD cars. I'll probably never have enough track to find out what 4th will do in this car because I can't even use 3rd at the track (17.95 @ 75mph). I certainly wouldn't try it on public roads because my hatch doesn't give me an overwhelming feeling of safety, and people generally don't appreciate other people blazing down the road at 2.5 times the posted speed limit. Especially not the cops or your insurance company.
On DSMs there's literally a resistor you cut inside the ECU box and it disables the speed limiter. DSMers are some cheapskate bastards, and they always find out free ways to do things that would normally cost other people money. Someone out there has to know how to easily defeat it on a Honda. I don't recall ever reading anything about it, but it might be pretty simple to do.
