F22a1/f22a4????

[musteredonme]

what make the power diff in A4 than the A1.valves/exhust/intake

[ExplodingCake]

Exhaust manifold design being tubular 4-2-1 on the F22a4. While the A1 gets 4-1 design.

ok cuzz i just picked up a 93 EX/A4 headers two days ago and just wanted too know why there was a 40-50 HP differnce

93 EX A6 header you mean not A4.

Ok here's the deal.

F22A1 - 125HP

F22A4 with tubular 4-2-1 Exhaust manifold over the A1 - 130 HP

F22A6 with dual runner intake manifold , different cam profile , different ECU and 4-2-1 exhaust manifold over the A1 - 140 HP.

oooo thanx for clearing that

40-50hp difference?

1993 EX has the F22A6. The exhaust manifold on that engine isn't much better than the one on the F22A1, if at all. The F22A4 was in the 90-91 EX, and has the best of the 3.

If you're saving for turbo, why are you wasting money on exhaust manifolds anyway?

why?

[deevergote]

Why what? Why is the F22A4 header the best? Because it's the only tubular header made for any of the 3 engines. The A1 and A6 have rough cast iron manifolds. Tubular steel > rough cast iron.

but if the a6 IM gets pnp'd it would be considered better right? only in the completely stock form is the a4 IM better then the stock a6 IM, is this correct???

[deevergote]

I suppose... but why bother to do that sort of work to a stock cast iron manifold?

The A4 header is a true 4-2-1 header. The A6 manifold is still just a piece of cast iron.


The $600 Bisimoto header makes it a moot point, though I'd just get that!

whoah, you DO know the discussion is on the exhaust manifold(header) and not the Intake Manifold(IM), correct?

ehh what?

INTAKE MANIFOLD = F22A6 is the best of the 3 F22A variations.

EXHAUST MANIFOLD = F22A4 is the best 3 F22A variations.

i know, but they were discussing exhaust manifolds and out of the blue he came w/ the IM topic, read through and you'll see what i'm saying

Yeah I did but I wanna put it on topic and keep it straight. He just thread jacked if he was goin for the IM's. lol.

It's like shifting to Reverse from 5th gear.

[93accordlove]

help this beginner please

i wanna stick with the reg f22a motors in my 90-93 accord is that good? i don't wanna go swap or go turbo yet.

and im thinking about putting in i/h/e, performance cam gears, performance crank shafts, after market fly wheel, stage 1 or 2 clutch, different ecu is that good and what ecu should i use for my f22a i wanna go all motor
