F,H or K series on CB7 ?

[10thAnnivCB7]

which one do you think would be better overall ,, drive-ability wise ,, performance wise and maintenance wise

[JoshM]

Technically the K series would be best, considering it's newer, less mileage, ample aftermarket support, etc.

The bad part of the K series is the initial cost of the motor and installation.

[10thAnnivCB7]

why do you think it is so expensive to do this swap ,, other than computers and sensors stuff

[JoshM]

Have you priced everything out? Or are you wanting me to write up a DIY?

[HardInThePaint]

Because that engine wasn't built to go in a CB engine bay. It doesn't just drop right in, so you have to have special motor mounts and whatnot.

yea ive heard about those mounts ,, i know u need a k20 trans and all that but i just dont understand why its so expensive ,, and yea joshm i would like a diy plz

I want to do a kswap too, but hybrid racing only makes mounts for the k24 block. I mean this isn't bad, it is a good thing you have to build a Frankenstein just to get decent power. Than than their are the hybrid racing axles and don't get me started on the wiring and it a hard build but there is one guy on here is a built and boosted k24...I mean I am going to do the swap just so I have a 300hp NA K series for autocross but if you don't want to take the time and money to swap it...build the F22a and you have close to or over what it would cost just to do a k swap

The H without any doubt. Aftermarket support, cost, easy swap. It`s all in all a very good and safe engine.

its expensive because just the motor and tranny run close to $5,000 unless you get a hookup or find them cheap, then you have to get mounts, ecu, shifter, etc. it adds up quick.

Hybrid racing is expensive and you would have to drop over a thousand for mounts and axles alone...than the price of the build, its almost not worth it in our car. and the k series drops right in to place though and fits like a glove

H. Simpler, very economical swap compared to K, and has lots of aftermarket support. Although the F is an amazing engine, the H22 should have been an option on CB's IMO...

I have seen fully built k24's for just under 6 so a k24 stock with a trans is 2200 to 3000

[10thAnnivCB7]

what about for a daily driver but with some power to still scare some ricers ,, K or H

[Jack93prj]

K series stock would do that...H pretty modified would also do that...what power do you want
