Ok guys so im looking at a EK hatch that has a B series motor in it all ready. Im wondering if it'll be a problem going from b series to h series since it was already converted from d series to b series.

Thanks

tempban

the same as going from d to h

twiztid_989

u r going to need shift cables and the shifter that goes wthe cables ecu trans mounts and axles for the swap

FearDisH22a4

Any different in electrical? does anyone i can get the step by step process on this swap?

im not faimilar with the step by step but to give you some info.. the B series and d series and B series were both designed to fit in the civic.. The H was not. so its like any swap involving a motor from a completely diff car

You'll run into more problems down the road...stay with the B

h2d or h2b all u gotta do is shave the block a lil bit and get mounts, bang 200hp civic unless u got money to build a beastly b, do the h22!

ReVeNgEd-SoN

The B18 is 200hp with a direct fit, rather messing around with axles lining up, mounts, shift linkage, etc., and is more reliable when boosted then H.

The b18c is, the b18a1 or b18b1 is just 140hp and 142hp

Running into problems like? The h22 is fully rebuilt the right way.I have a thread up on here on honda-tech in the prelude section if you guys want to check it out.
I am not boostin im all motor.

its the same as doing a H swap any other time. There are DIY threads on here for how to do it.

mikej94civex

the b18c5 is the only b series, stock for stock, that is comparable to the h22...plus it's alot more
money, an h swap can b done for 2-3k and with h2b it's like a k20 from what i hear for half the price!
don't get me wrong tho an itr swap (b18c5) would b hella sick too!

Not true...That's about 195 @the Crank..not at the wheel. Most you'd see at the wheel on a stock set up is probably about 150-55, an h22 will yeild a tad bit more over that at the wheel. Even MORE if it's a JDM H22 out of an Sir or Type S which would garuntee about 170 or more to the wheels although there is a guy on here who dyno'd about 180-190 at the wheel on a stock JDM h22 block..

GOing H over B has it's advantages, it's only disadvantage is that it's the more expensive route and Boosting will cost more later down the road ONLY if that's your goal.

Jimster480

explain your logic there? a H22 has less power loss to the wheels than a H22? NO.
Hondas have about a 15% power loss to the wheels. Meaning 195HP = 169.5WHP
200 HP = 173.9WHP. Not even 4WHP difference. So idk what your talking about 190WHP on a 200HP motor because thats a 5% loss and not realistic.

what about the extra 40+ftlb of torque.

ReVeNgEd-SoN

Yet the H is heavier then the B so those factors also weigh the difference...

ek4_b16a

^^they're not that much in difference by weight. it doesn't matter. just do it

Jimster480

its only about 30lb more than a GSR/ITR

4.8t

and a few thousand cheaper than itr. at our weight 30+ftlb is a lot, hell its almost a 30% increase in torque. either way a nice torque curve makes driving so much fun. its nice to be able to shift at low rpms sometimes and not have to be at 4000rpm or more while cruising down the interstate.

Jimster480

4000 RPM or more is due to the transmission. so H to B would have the same problem.

4.8t

who said anything h to b.

Jimster480

mike did up in this page

4.8t

but the OP didn't.

First off YES, an H22 CAN HAVE less power to the wheels then an H22 if ONE is a JDM H22 from an SIR and the other one is a JDM H22 TYPE S. The TYPE S is rated at 220...the SIR is rated at 200. GRANTED your math is correct as you've so willingly displayed, you'll come to find that 187@ the wheels (Type S) and 170@the wheels (SIR) are DEFINITIVE and BEYOND marginal differences, trust me, 17hp is MORE an appreciable GAP that WOULD show up in performance trials. EITHER in comparison to the 165.75@the wheels is a better deal when you consider that BOTH will DEFINITELY give you higher torque numbers..If ONE car has 165@the wheels, lining up against a driver of equal skill with 170@ the wheels, ONTOP of the 5hp advantage, the H-driver has a significant TORQUE advantage...

WEIGHT is going to save the weaker motor and if that's fail, it's a LOSS.


H over B in this case, for the money, you're getting better performance overall.

WavyIntegra

THAT'S what you go H for. Indeed, horsepower is important but even if it's to the moon, what is it without TORQUE?

IN an ITR, at the wheel you're giving away to an H in the power department regardless albeit SLIM depending on the Type of H, but you're giving away LEAGUES in Torque to either by comparison and that's where you're actual PULL comes from, not to mention that in the B you're going to have to look HIGHER in the revs for you're still inadequate amount of Torque in comparison.

B's have the higher fanbase because they are cheaper and relatively easier the mod..I can respect that...but the H's superiority can't be denied in it's allocated categories, but if you address it's weaknesses (Ring lands if your striving for power involves bumping compression up or adding a turbo), and it'll outperform or match ANY B you throw against it that isn't BORED out to it's dimensions.
