F23 vtec swap into 91 CB7 5spd EX

[91-accord]

Has anyone done a f23 vtec swap into a fourth gen before? Which parts are interchangeable which aren't and what else is needed? And last but not least, were you satisfy with the outcome of the swap? Did the vtec work out? Please someone let me know thanks.

probly not worth the money at all

[91-accord]

any reasons why? I mean I can get the motor and tranny from my cousin for nothing.

SOHC vtec just isnt anything to write home about

[deevergote]

SOHC VTEC is worthless. The motor is OBD2, so you'll have to convert... not hard, but another step. A few people have done it had run into weird problems. If your motor isn't in bad shape, don't waste your time. The transmission can be used on your car (I'd keep that as a replacement and sell the motor)


If you want to do it though, it's similar to the H22 swap.

If you want more displacement why not just sleeve your engine? But if its a little performance your after there are lots of other easier ways to get it.

[91-accord]

It's not the displacement that I want. I want a slight gain in horse and torque and vtec as well. Although I also have a short block f22b. I was planning to get a f22b vtec head or otherwise go with the regular f22b single turbo charged using the dsm set-up. Oh, I am also considering swapping out my tranny for the f23 tranny. Are the trannys interchangeable easily?

I'm about to get in the same boat as you 91-accord. The only reason i'd like to possibly do this swap is because the f23 is being offered to me at a low price. I'm not after the higher power & torque numbers, but more on having a healthy, low mileage motor. If the motor will be sold to me at $150, is it worth it? or should i just pick up something else.? what are your opinions..

[Leung]

i'd take a low mileage engine for 150 bucks but seeing as mine only has ~135K on it, i'd probably just keep it in the corner under a cover so nothing happens to it.

It's can be done, This is Samuri88 wagon with a 5 speed tranny

Tap one hole for the tranny. Easy.

As for the SOHC VTEC... it is NOT an upgrade. Additionally, the DSM manifold will not work with a SOHC VTEC head.

ha..thanks richie for the post.
but yea it not the best....but i like it...i got mine for free..from a 98 auto cl.
then i did a 5 speed swap 2 it.
this is me..." if its free or a very low price go for it."

[deevergote]

" if its free or a very low price go for it."

I agree. If it's cheap or free, and in better condition than what you have... yes. If you want to pull out a perfectly good F22A to replace it with an F22B1 or F23A expecting an upgrade, you're going to be disappointed!

thanks for the info guys..

so H22 is the thing to do huh?
