difference in f22 motors

[recliner54]

how much better is the F22A6 compared to the A1 and A4?

[Accrdwgnguy]

A1 is 125hp, A6 is 140 hp. So 15 hp.

Slap an H23 plenum and TB on there, real easy.

the F22a6 has 140hp and 142 foot pounds of torque while the a1 has 125hp and 137 foot pounds of torque and the a4's got 130hp and 142 foot pounds of torque.

the main advantage you get from having an F22a6 is the PT6 ECU and stronger valve springs for an upgraded camshaft.

ha i looked at that thread earlier. but like i know thw A6 has a more aggressive cam than the A1 and A4. what about the other internals and how much power would an A6 be able to handle with stock internals?

[Accrdwgnguy]

The internals are pretty much the same as the other F22a's. Really the only difference is the Cam, valve springs, windage tray, oil cooler, intake manifold, and exhaust. There may be a few other things I am forgetting.

Besides your auto tranny will explode before you hit any numbers that will kill the engine.

In my opinion if you wanna go stock a6 with bolt-ons and what not, you're probably covered up to 200hp. If you plan on going higher I would strongly suggest taking some precautionary measure

[recliner54]

i do plan for a start to hit between 250hp and 300hp with a manual tranny

[JDM AlEXiTO]

hmm..are you gonna boost?

[recliner54]

im going back and forth on the boost. i would like to have internals than can handle it so if i do decide to boost it i know i wont have to do anything internally.

Well, if you're still on the fence about boosting, but still want to be prepared if you do end up going that route, the best thing to do is make sure the engine is healthy. Most times, a rebuild is the best way to go. I have an F22a4 and I'm just looking for the right time to pull it out and start building.

Sleeving also helps in maintaining strength; stronger pistons [maybe even forged if you've got the money, also depends on how much boost you plan on implementing]; and most definitely get some professional advice lol

Dont forget about the dual runners!

[deevergote]

You will NEVER get to 300hp with stock internals NA. Boost, you're going to need a good tune, a healthy motor, and good luck to pull that off for any amount of time.

The F22A motors all have the same internals. Accrdwgnguy listed all the things that make the F22A6 different from the F22A1 and F22A4 (the F22A4 is identical to the F22A1 aside from the exhaust manifold)

so overall you wanna go with the a4 or a6?
or does it depend on something?
