best f22 to put build up?

[P3dr0]

i was wondering which f22 is better to build. I want to build an all motor f22 but im not sure which one should i use. I have a f22a1 right now, so i was thinking about getting the a6 but then i thought i might as well get a vtec f22 if im gonna stay with the f series n do a swap.
what do u guys think? which one is the best? and which f22 can handle boost better?

Since you seem to be talking about the f22ax:

They're all the same with minor differences. Since the things you need to do to properly build that motor up involve replacing those differences, it doesn't matter which one you start with.

[deevergote]

The F22A blocks are all identical. The F22A head castings are all identical. The only parts that are different between the F22A1, F22A4, and F22A6 are bolt-on parts (the F22A6's intake manifold and camshaft being the most signifcant upgrades, along with the ECU that is programmed to use those things)

The SOHC VTEC F engines are actually a considerable downgrade if you're looking for a platform to modify for performance. The valve angle and port design is inferior to the F22A.

If you have an F22A1, and you want to make some real power with it... here's my suggestion:

Get a Bisimoto header. $630, and a lengthy waiting period... but the gains from that single part alone will be greater than a SOHC VTEC swap.

Get a Bisimoto camshaft. Stage 1 or 2 would be wise. 2 requires some valvetrain upgrades.

Get some headwork done to your F22A head (or, probably better... get a spare head, they're cheap, and have that worked)

Get an H23 intake manifold and throttle body.

Upgrading the bottom end would be smart, but if you want to go the cheap route, at least replace your rod bolts with ARP bolts. It will rev more safely with those.

A 3" short ram intake with a quality air filter (AEM or K&N), and a 2.5" exhaust would also be very smart.

Finally, once all that is on... a P06 ECU, tuned on a dyno...




That setup would very likely get you near, possibly over, 200whp if your bottom end is healthy.






If you're looking to boost... the F22A is the cheapest and easiest option. ANY F series motor will give you a fair amount of power with turbo... They'll all get you a little over 200whp before you need to worry about reliability (assuming you're using the correct parts, you tuned it properly, and your motor was healthy to begin with)

yea ive seen the bisimoto header and ive been meaning to find out what process do i have to go through to get one

[deevergote]

Check out the Bisimoto Member Shop on this site. That will give you plenty of info.

a6 intake has IAB's
a6 also has a windage tray, a1 does not
but if you don't have an a6 then you can get those parts at a jy

how much boost can a f22a4 hold up to?

All sorts of great info in this thread!

I don't mean to thread jack, but since you brought up boost is there any other things in the bottom end that are important to upgrade for boost? Possibly things that often break/weak/bad design?

[JoshM]

There's not a magic number. It all depends on your motor's health, your turbo parts (quality), your tune, etc.

The weakest part of a stock-block F22A when boosted is the piston ringlands... so running forged pistons would be best. With a reasonably low boost setup, using a properly sized turbo, tuned very well... and carefully maintained, not abused... such a motor SHOULD last quite a while.
I've known many quality builds to last a couple years before the ringlands went... but regardless of how well it's put together, it will eventually break.


russell707, this thread is over a year old, and the original topic really doesn't have much to do with your question. In the future, if you have a question that isn't DIRECTLY related to the topic of an old thread, please just start a new thread of your own.

[Ander]

Wow I didn't even realize how old this thread is

Do you have any suggestions as far as a brand of forged pistons? Something affordable (not cheap) would be ideal.

[deevergote]

I've never dealt with any directly, but I'd probably go with Arias pistons from Bisimoto... mainly because I feel that if Bisimoto trusts a brand enough to sell them (and I assume run them in their project cars), then the quality is top notch. The pricing is acceptable, and I like to support companies that cater to our platform... because there aren't many of them left!

[Ander]

Well I will definitely talk to Bisimoto and pick their brain about pistons as well.

Thanks for the info Deeve, I really appreciate it.

Didn't the A6 also all come with an oil cooler infront of the oil filter?

certain ones my coupe 93 ex manual did not have one but my wagon 93 ex auto did have one
