Default H2B vs K

I've been reading a lot of debate on which is better on many different forums. I come to think it might be a good topic here on this site. I've tried looking for a thread about this on this site couldn't seem to find one, but I could be wrong.

So basically good and bads, opinions, experience etc.

Got the poll up to see what they would choose.

I have always kind of wanted to do an f2b with a ls trans and a big turbo

Matt, stay with a real transmission. So many reasons to. LS transmissions just put a lot of stress on parts.

Wait why's it put more stress on parts? I know that might be a stupid question but curious.

Well im guessing with the shorter gears its easier to turn. So you get more tq to the wheels. So longer gears would be harder to turn, harder on parts, and robbing tq.

Is that wrong?

I hated my H2B, even when it worked right I didn't like it. Love the H series motors tho. If money wasn't a factor I would take a K series over an H but since money is always a factor and there is a big difference between the two I prefer the H motors.

I own a k swap car, have friends owned h2b. Imo k series is better with newer tech and design. But h2b is very impressive matching torq freak with short geared b series transmission. Dollar for dollar stock h2b beats stock true ivtec k series. But extra cost of k swap is worth it imo. Faster, more reliable, better mpg, better drivebility, and like anyone modding cars care, lower emmision.

I don't think the cost difference is really all that much when it comes down to it. Yeah motor and trans are cheaper but you have to buy a lot more in order to do h2b. H2B kit, clutch, flywheel, intermediate shaft, axles, alternator relocation, h2b manifold (there aren't any cheap ones out there that I'm aware of), mounts, other misc things.

I don't have any experience with K series tho so I don't know what the cost is exactly on those so I could be wrong. Also if you already have a b series trans, intermediate shaft, and axles I can see that saving a lot there so in that case for sure the H2B would be a lot cheaper then.

Taller gear ratios cause a higher load during acceleration. The weight of the vehicle also has a lot to do with it. I would go with a slightly taller tire over a taller transmission. Plus the LS/B16 differential cages are tiny. GSR cages are close to an H22 in size.

So Mike, if you had no cash limit and could build one of these two, what would it be and what main parts would you use? Without going into tranny internals, engine internals etc.

Default Re: H2B vs K

I would build another H2B again in a heartbeat. I still love the concept of it. And still hate cable shift mechanisms. Beyond that, you spend equal money on a good header either K or H2B. The H2B uses an easily replaceable set of axles. Everything else is stock parts. The H2B should have a custom oil pan and pickup (KS if you can find it), BS delete kit (KS as well), alternator relocate, Clutchmasters H2B flywheel, and preferably a 98+ JDM ITR transmission. Everything beyond that is just little piddly stuff. Far cheaper than a K swap by that point, and still just as fast, stock for stock in a matching chassis. Shoot, for the price difference on the swap alone, I can build a stout H22. But really, just my opinion. Both are excellent options.

Default Re: H2B vs K

I don't know much but here's my thoughts....

When this discussion comes up, i break in down in a few categories:

1) $2,000 - $3,000 budget?
stock h2b with nice boltons & short gear tranny
easy 210-215whp
soild street/strip setup .... nice torque for many types of driving.

2) $3,000 - $4,000 budget?
semi built h2b (good boltons, cams & head work)
230-250whp
easy low 12's in lighter 2100lbs car

3) $-6,500-7,000ish budget
kswap car done right
215-225whp with boltons
newer motor
better technology
expect to pay high prices for latest development in tech parts

4) $8-9k into Kseries engine & tranny swap setup...
i hope you know how to make the most of it.


H is a decent platform. I personally perfer B series. H's have the displacement, so it makes it very attractive platform.

K series, your buying into the "future" & the hope that one day you will know/have enough money to max out it's potential. It's not that Bs or Hs can't make power, they do, they are just slightly less efficient than Ks. But honestly, when you get into the +500whp turbo category, nobody cares if it's a d,b,h,f or K.

For NA guys I think that power threshold is like in the 270whp range.
Nobody cares if it's b, H or K. Power is power.

My friend Jordan always said, making power is the easy part but in the end, it's how the car is setup to deal with traction & handling.


if you go the money & plans to stay in the game a loooong time, then jump strait into ks.
If your a budget type of guy and just want a fun car, go h2b..... great bang for buck

Charlie

^ agreed with this guy.

but K series can make more power N/A with less work. 270-300whp n/a can be done with all offshelf parts, and its not much more than building a B series N/A either and make alot more hp.

While i agree with you on the k>h statement, i absolutely disagree on a k making that much whp without a bunch of internal work and "off the shelf" parts. 220-230 sure. No hate intended.

Actually stock motors with a radical tune on K pro will make a good 30hp in gains.

There are people with stock internal K20, with intake, header, exhaust, and a crazy tune on K pro making over 230whp. 270-300 on off the shelf parts is not a problem.

I would like to see some links to this, only reason i say this is bc I haven't seen a k20 with basic bolt-ons (dsm owners need not apply) on kpro make over 220whp. If 270 is to be reached, that tuner must be awesome.

sorry didnt clear my comment well, offshelf part consider aggressive camshafts, valve spring, retainer, piston, rod, arp bolts, with full bolt-ons include stock rbc intake manifold bored out to 70mm match with after market 70mm TB, race header, 3" exhaust. this should make easily 250-285whp depend on how aggressive the camshafts are and how high compression.

ill look for some links, its been done for a while now, while for h or b to make that much power usually include alot custom spec parts or full race port , taller block, bore out more displacement etc.

this is a stock type r k20 with drop in cam from drag cartel, its basically stage 1 cam, almost 240whp, while they are 220 to crank and most likely book 180-190ish to the wheel all stock with no kpro or ecu tunning, 40-48whp gain is amazing from kpro and basic cam!

http://www.k20a.org/forum/showpost.p...&postcount=566

this is all done with stock k24 bottom end, most k20/k24 frank make 225-240whp with all stock head and block, just bolt-ons and tune.

http://www.k20a.org/forum/showthread.php?t=54746


this is a great site to look around to feed information on. i learn alot more about engines at this site than any other!
