street legal in cali?
its hard to say about that, i wanted to replace my engine with another f22 engine, ppl say as long as the engine is 2.2l and around the same hp output, the technicians wont care.

 

cheaper yes, easier no way. you gotta spend so much time/energy in parts shopping/tuning...not to mention all the work done to make it fit together...it's doable, but it aint no bolt-on

 

hah, and you dont have to do that when you swap a whole new engine in your car! You dont even have to pull out the engine, re-wire the WHOLE thing. Plus on any engine swap you have to tune your engine. And fabrication- hah, what fabrication? Honda bond and a couple holes, thats barely considered fab work dude. And it fits almost perfectly when you pull off the head and stick it on a f2x bottum. So i guess youre right by saying its not a bolt-on, but its damn close to it and a helluva lot easier.

 

you have to take the block out and order to send it to a machine shop. getting the head honed and blocked bored is not very cheap and easy either. might as well sleeve the f23 block and stick some wiseco 9 to 10:1 pistons and eagle rods and call it a day for the block.

mating a stock f23 block to a stock h23 head is not going to achieve the same results that particular 'hybrid' came up with, the nice dyno #'s is due to the high compression.

if you can get all those parts and machining for 600 bucks you got a good hookup.

generally in 4th and 5th gen accords, a swap will be easier since stock and prelude mounts work and no fab is need. 5th gens with vtec are even easier on teh wiring.

that guy had lots of parts lying around and had great hookups and did alot of the maching himself.

 

to answer the legal question in CA, no it is not legal. period. no smog ref will ever pass it no matter how clean someone can make the engine burn. its not a legal engine. meaning, you want that engine, you better have it smogged at a test only center that you got hook ups with and never report the engine modification to any records, especially DMV obviously.

this is completely different from swapping in a whole engine in its entirety into the car, which is only legal if its of the same year or newer and has all the appropriate smog emission control devices.

bang for the buck, nitrous owns. hands down. that guy on HT had great resources to do what he got done.

 

95SiR....
i hate you. You just crushed all my dreams and aspriations--are you happy? huh? are yuh punk?

 

oh yeah and the wiring being easier than a swap its not. you have to do and obd conversion from the f23 obd2 to obd1. that right there will instantly fail your smog.

pay some cash under the table to some hole in the wall asian smog shops and they'll pass you. that how all my friends and myself get it done.

 

So is a F23A block with the H23 head and a H23 or h22a tranny better, then swaping the entire F23A with a h22a ??? Also isnt a H23 a OBD2 head? cant we retain the OBD2 status and pass the smog?

 

it was converted to obd1 mostly for tuning issues. engine management systems are not obd2 friendly. with 12.5:1 CR on pumped gas you better have some sort of standalone. once again the only reason this particular hybrid made good numbers is because it has high compression pistons which the block was overbored for and head decked.

there was alot more work involved besides just slapping a stock f23 block and stock h23 head and and h-series tranny together making it work and have those kinds numbers.

ive seen this spreading on a few of boards now and i see alot of people posting that they are going to do this build in hope of accomplishing the same numbers but dont really understand whats involved. if you were going to build a custom setup and have maching done then might as well go all out. the only reason this guy did it cause it costed him almost nothing for the machining and block assembly.

if i were to pay to have maching done on a block cuz i sure as hell dont know how to do it or have any hookups on it, id just build my stock motor for boost. or if you got the funds start off on a stronger platform. you can pickup a h22 long blocks for $1000 all day. if your going to have pay to have machining done i.e.boring and honing, etc..., then why not go with some forged pistons like wisecos and eagle rods. upgrade to some skunk2 valvetrain (and keep boost in mind).

 

One could substitute H23A1 pistons for H22 pistons in this case, as the H23's have a shorter compression height, and would most likely fit.
