no mistake with a 2.0. iv'e had all three of the engines and can say that i loved mine 2.0 with the six speed but not enough to marry it. the hatch came along and caught my fancy, along with the mod bug. then the coupe just happened , took a while but its the best style of the bunch.

Just a WAG but... I guess it’d make sense in a way for VTEC engagement to be at the top of the RPM range on the CVTs if that’s just below where RPMs lock during peak acceleration and hold the valves more shut for drivability down low but choke it out from making substantial power unless you’re absolutely at peak RPMs. Not much sense for a manual though. Then again, Honda never seems to have picked the optimum crossover for maximizing the area under a power curve. The old A2 had practically choked out by the time they had crossover... the ‘VTEC kicker in yo’ wasn’t really a good thing. It showed how poor the car was making power before the cross over... I suppose to just hold a window large enough to allow shifting at redline and holding RPMs past the engagement point. The fact torque had long peaked and crashing long before VTEC crossover made for a practically hesitant stock tune as you reached 5000 RPMs.

The old A3 had VTEC-E though for efficiency way down low. If these C2s have traditional VTEC, intake side only albeit, it’s odd that they picked virtually the same crossover as the old A2s. The A2s still had a 2000 RPM of room to grow. I think this is ultimately the Achilles heel of the engine as even with a lowered engagement point, I don’t know that you’d stay in the VTEC engagement range for the engine on a manual, even shifting at redline... and all those noticeable gains are right there at the tippy tip of the power band.

Still, that 22 whp bump, even if the window is pretty narrow ought to be quite noticeable given the power levels you’re starting with. Like the A3s... you’re just out of room to rev as things should be getting interesting.

Good news is, if you decide the tuner juice isn’t worth the squeeze (and if your sticking with the car, I think it’ll be the best bang for the buck you can get) you can always flash back to stock, unlock and resell it for the majority of what you paid for it.

I bought mine specifically because it got the 2.0. Need something that works in winter too :)
Yeah my 1.5T just doesn't work in the winter :rolleyes:

People say the dumbest shit on this board to justify their actions

I'm guessing like everything else these days it was in an effort to maximize mpg's and help Honda with those CAFE numbers.
Probably, but my mileage hasn’t changed with the tune though. It’s just more powerful

You have a good point about the changeover. On the new 2.0 it has more available torque at low rpm than the old 2.0. So the changeover just continues the pull. It’s actually a smooth transition

So I’m new to all this but is there any reason that in the next couple years a company wouldn’t make a turbo for the 2.0Na? Because myself like others was very disappointed in the aftermarket selection. For the 2.0Na

Maybe, CT Engineering made superchargers for the older NA K-series cars... but they went under late last year. I’ve heard Honda’s move to providing factory turbo cars really crushed them (they make super chargers for the K20/K24 car’s all my with the F20/22 S2000s and whatever the 1st gen NSXs has). There is a thread or two about head swapping the K20C2... and with a head swap, grabbing a used CTE SCer might be the best bang for the buck out there for power. Maybe they’d work with the existing head, but I’ve got no idea. There already one brave/foolish soul who cobbled together a turbo kit and paid a good deal of money to match the performance of a reflashed L15B7.

The oldest CivicX is still only about 4 and none of them are dirt cheap beaters. You’ve got to decide whether putting thousands on a K20C2 is worth it vs just trading out for a L15B7 powered car with the ease of reflashes and aftermarket support... much of which is relatively inexpensive compared to buying parts and paying for the labor for install.

Making a turbo kit for the car isn't the problem. The problem is the lack of a non-standalone, tuning solution.

As for parts, I wouldn't expect much outside of bleed down parts. Why? lots of people with lower-trim/engined cars talk about buying aftermarket parts, adding turbos, etc but few do.

For example, lots of r18 owners on the 8th and 9th gen forums begged Hondata to release a tuning solution. Hondata released a tuning solution and they sold dozens of them.

That BMW had to be crazy slow. 16.9 in the 1/4 is definitely not blazing. :drive:

Thanks for posting the numbers though. :thumbsup: Look forward to your times with the KTuner and hopefully you can post the timeslip. You'll be much faster with the tune, better tires and reduced weight.
I think stock odysseys are faster :lol:
