will a 1995 accord ex with a f20 motor pass smog?

 

 

sk1t depending on your region it may or may not pass due to the engine identification stamped on the side of the block. A savvy tech may note the 'F20' and fail you if your Accord is supposed to have the F18 or F22. But since we have no clue where you live or what exactly you mean by your question, H-T members cannot help you... yet.

 

well i live in sacramento california...is that enough information?

 

no

 

First off why would you want to downgrade your F22 equipped Accord with a smaller and less powerful F20 variant?
The only F20 that might be worth installing is the DOHC BlueTop, but even then it would just be more economical to locate a H22 which would have more torque anyway.
The F20C from an S2000, although an F series, is completely different from the rest of the F engines. It rotates the wrong way for use in an Accord.

Use an H22 from a Prelude, it will be cheaper, easier to find parts, and it has been done.

 

i believe he is talking about the dohc version....i hope

but until the op decides to properly list information, use the forum, and the search button...then i guess well never know

 

well since a f20 is lower on torque then do you really recommend me getting a h22 instead? if so which one do you think will be better? the H22a or the H22b? but will it pass smog?..sorry I'm not that good when it comes to the performance work. one more question does it matter if on the motor it says it's a 97? will it fit a 95 accord?

 

If you are going to swap in an engine, you may as well swap in something that will be
1) more powerful
2) easy to swap or easy to get common parts for. IOTW its been done.
Well I have never heard of a H22'b'

And as for the H22A family...
# 92-96 H22A Prelude Si VTEC (Japan)
# 94-97 H22A Accord SiR (Japan)
# 97-01 H22A Prelude SiR, SiR S-spec, Type S (Japan)
# 00-02 H22A Accord Euro R (Japan)
# 93-96 H22A1 Prelude VTEC (America)
# 97-98 H22A1 Prelude VTiR (Australia)
# 93-96 H22A2 Prelude 2.2i VTEC (Europe)
# 1996 H22A3 Prelude VTEC (KU)
# 97-01 H22A4 Prelude SH & Base(America)
# 97-98 H22A5 Prelude (Europe)
# 99-02 H22A7 Accord Type R (Europe)
# 99-01 H22A8 Prelude (Europe)

But to keep headaches to a minimum the H22A1(187HP) or the H22A4(197HP) would be the legal swap as it is available here in Ca. Remember, our engines have a nice giant stamping that states what block is in the car right above the engine mount. A keen smog techie will know that.
The engine will pass physical smog testing no problem. It's the visual and documented part that is the issue. If you are pulled over by CHP and they have you pop your hood, and you have an undocumented swap, you can be heavily fined, and the car impounded. Ca has no issues with engine swaps, the issue is an improperly done or non compliant swap. Parts that are E.O.'d or C.A.R.B. approved are your friends.
The rule is you cannot have an older model engine in your vehicle. Same year or newer. Along with not a larger engine than what was available.
That '70 454 big block Chevy into your '84 Cavalier is not going to fly.
The H22 will fit.
I suggest you check out the Default ► 1990-2002 Accord FAQ and scroll down to Swaps

Call up your local CHiPs, and Referee station. Also talk to your regular smog test tech. They will be able to point you in the right direction. Usually when a swap occurs you will go to a referee station where they will verify all the correct and applicable emission devices are intact and operating, test the car, and upon passing/completing they will affix a sticker to the doorjamb noting that the car has a legal engine swap.

 

thanks man you answered all my question. I appreciate it

 

1 more question. will the h22 be good with the accord transmiton?

 

The Accord transmission will work with the H22, however the gearing in both the A/T and M/T are different between the two cars. It's externally the same transmission, but internally the Prelude transmission will have shorter gears for quicker acceleration. Where as the Accord is geared more for economy/cruising.

If you go back to the FAQ, under drivetrain there is a link to the different transmissions and gear ratios for both AT and MT cars. It's called F/H gear ratios and is near the top of the Drivetrain list IIRC. Depending on what you are going for there are differences even amongst like models. The Accord Wagon has the same gearing as the Accord Sedan/Coupes, but shares the final drive of the Prelude.
