I've got a '92 S, with 163K miles. Its in decent condition, but I'm wondering if it would be worth modifying. I love the car, but there just isn't much out there for the f22. I am kinda new to this as well, but very interested. Thanks for any suggestions!

 

F22 is supposed to be a good engine to turbo.

If my S hadn't been stolen, I'd still be quite happy with it, especially with gas prices going up. It's the lightest of the 4th gens by at least 200 lbs, so if you put some Si stock wheels on it, it will handle better than the Si or VTEC. If you turbo it, it will be way fast, and you can get almost the same gas mileage in the city just by not using it when you don't want to.

F series motor: 135 hp
H23: 160hp
H22a: 200 hp (jdm)

With your F series motor the only way to really make power is going to be turboing it. Alot of guys will say this is a good move because The F series engine is ran at low compression and can handle more boost then it's high compressioned brothers (h23 / h22).

Others will say no due to the rep of F series motors being supposively weak. Just because the F series motor has low compression doesn't mean it's going to be a good motor boost, For example: a geo metro is ran at low compression, does not neccesarely mean it's a good motor to turbo. Lets say you decide to turbo it lets look at cost...

a F22b2 (non-vtec sohc) boosting 6psi dynoed 168hp on dynojet (un-tunned). Somewhere I read a F22 tuned at 7psi on stock internals claimed 180hp another claimed 195hp. The f22b2 supposively can handle 8-10psi daily driver on stock internals.

Turbo kit: $2,000 - 2,500
Installiation: $1500

Now that's just about $3,500 roughly, You also need to get better fuel management system + what ever turbo goodies you want or that didn't come in the kit (gauges, timer, exhuast piping, ob2-ob1 harness for new fmu etc..).
Being un-tuned if you go greddy's stock 6psi you'll have 168 dynoed.

$5,000 turboed F22: 180-195hp (depends the quality of who ever tunned it).

H22A 92-95 Complete Change Over
200Hp 161Trq 10.6 Compression (JDM)
190Hp 156Trq 10.0 Compression (USDM)
$ 2199.00, + labor for installiation $1000-1500.

Or even H23 160hp for $900 + labor.

It's either turboed f22 to run a little less or as fast as an h22a swap.

I think The swap looks like a better deal. Good platform, N/a reliability... less headaches.

The S doesn't have an F22b, it has an F22a. I don't think he'd swap to a different SOHC motor just to turbo it. Also, why are you comparing a Honda Prelude motor to a Geo? :slap: :squint: F-series motors are very reliable, and the fact that they are slower doesn't change that. They are iron block, which means they don't have to be re-sleeved. The long gearing is an advantage for turbo too.

Thanks for the suggestions, I was thinking of doing the swap, but I don't have much money. Also, with a H22 swap, I would have access to many more parts. Any other suggestions?

 

I made a typo, F22a, Hes not swapping in a sohc, H22a (dohc, vtec). Why am i compairing Geo metro and f22? Because the common defense that the f22a's low compression ratio makes the engine good for boosting is not neccesarily true.

Longer gearing would take away a big part of your advantage for boost or anything. Long gearing = fuel economy, not performence. In no way is longer gearing an advantage for boost.

Here's what hes looking at is the price difference in his two options i believe is the best choices. The cost of doing a reliable turbo set-up on the f22 will yield you the same gains as swaping in the h22a. It will cost more money in the maintence, become less reliable do to the FI and be more hassle.

Bottom line, save for the h22a for a better platform to mod. You'll see, no one has gotten an h22a engine and switch back to f22a but there are stories of boosted f22a motors failing or people have swaped to h22 after turboing the f22a.

Of course there are well built f22 motors but is it worth the cost of putting money into the f22 motor where you can spend less money and mildly build the h22 and get the same performence?

 

Thanks FooD2000, I'm wondering something though. Would my tranny from the f22 be interchangable, or would I have to buy a different one.

 

The f22 tranny and H22 are all the same, and will bolt up. the only difference is the gearing inside. If you decided to do a complete swap though, you don't need to worry about this.

The F22 transmission is the same transmission with different gearing. I dont believe that the relability is different between the transmission. But the gears are very very long which makes your 1/8 slower, at least with NA.

One guy did a swap from F22trans to the SI trans, his 1/8 time was 1 second faster, thats a big difference.
