Honda Prelude Forum

OK so im having this problem some of my friends say that i may not be able to do the h22 head on the h23 block because the h23 is bored 30 over and is now a 2.3 and they say that since the h22 head is a 2.2 that it may not work so im confused can anyone help me with this

might as well buy an h22 long block or get a euro accord h23 vtec.
i have read numerous threads about people running into problems with doing frank h23/h22 builds.

well were can i find a euro accord h23 vtec at can u post a link of were i can find one and wat kind of problems have people had with the frank h23/h22

more info on the frank motor... all parts needed and issues people run into. seems like it isnt really worth it unless you are completely building the motor.
H22 head on H23 block - Honda Prelude Forum .:.

just search for h23a vtec on google... you will find stuff like this.
Honda Used Accord Prelude JDM H23A DOHC Vtec 2.3L Blue Top Engine Only

or contact legit companies like hmotors. call them up and find out how much they will charge you for one. a buddy of mine got an h23a vtec for his 93 prelude at a great price from hmotors. Specializing in JDM-USDM Engines & Parts...hmotorsonline.com

Frank motors can be extremely reliable if built properly. Here's a link for more info in addition to what Zac provided:

yea... thanks for adding on.
anything can be reliable with enough money into it. there are plenty of frank h motors out there that are reliable and done properly like dbd6604 stated.

the only thing is... why go through the hassle of doing all this work to matte the h23a bottom end to an h22a top end when you can get an h22a from hmotors for $1200 shipped? to each their own though. if you are building it and doing it right or just want to do it... it may be worth it.

Because there's no replacement for displacement.

A member here, Blake (98Vtec), is running a frank setup and he has one of the fastest N/A Preludes in the world. You've probably seen him around on one forum or another.

yeah a frankenstein can run hard properly worked on, we should just make a sticky of what each motor provides like h22a, h23vtec, the frankenstiens, etc. and which one would bring the most power for both the 4th and 5th gens

i still have those 3 motos in the back of my head for a futrue turbo swap for my car but deff still havent made a choice yet.

link to his thread? the additional displacement will help with torque but i still dont see it as being that beneficial. if it is done right it could be nice. i would personally go with the h23a vtec setup because its a factory set up.
but then again i am building a k24/k20 frank motor for mine so thats not saying much and i seem like a hypocrit. i just havent seen very many successfull h franks i guess.
_zac

Well K motors are much easier to do frank setups on correct? You dont need all this different crap and this and that like you need for h franks for b franks? I think i remember reading it, its just bolt on and go?

But yeah also think about the F20b thats a very good motor, essentially a 2.0 liter version of an h22a. Big mike uses the f20b in his prelude and achieved really good numbers with it i remember reading.

ya mike is pushing 211 whp and thats on a stock bottom end and they ran out of time tuning it if i remember right. you can see great performance from most applications. and yes k series franks are pretty much just bolt and go. :)
Aries had 222whp on his h22 with a stock bottom end right? the endyn n/a h22 put out like 280 whp i think. possibilities are endless when things are done right... and having the money to do it right is also a bonus.

G23 anyone? Lol

if you are going 30 over you just need to clay it up and make sure the piston is lining up properly w/ the head and that there is no contacted. obviously a bigger bore sized headgasket is needed.

i am in the middle of building a h23 vtec frank....setup as follows w/ pics
2.3 h23a1 block/crank/girdle/pan/tbelt tensioner
2.2 h23a1 rods w/ h22a jdm 10.6.1 cr pistons... 11.1 on 2.3vtec
2.2 h22a4 head complete
2.2 waterpipe/waterpump/timing gear/timing belt
kaizenspeed balancer shaft eleminator kit
2.2 oil squirters
crower stage 2 cams
supertech dual valve springs and retainers
mild pnp
balanced w/ lightweight flywheel and underdrive crank pulley

this will be up and running by the end of august.... :::crosses fingers::::







not in any type of order...yes i painted it before removing pump and shafts.... i am going to repaint it again.... block might end up black instead.
soooo far
here is the stamp ... almost forgot ... might shave the 1 off
