How to make 30+hp for $500 or less... (DX/LX F22A1 only)

[wed3k]

i passed smog with an A6 cam running a pt3 ecu and personally i dont think the h23 upper plenum will affect it. as long as there are no vacuum leaks and the TPS is set correctly.

[b3nsonx]

i passed smog with the mods listed in my signature, but im just worried that swapping the other parts will give me trouble

h23 intake manifold and tb, here i come!

[Losiracer2]

I passed smog perfectly with I/H/E. aem cold air, dc sport header, and Greddy evo 2 2.5 inch. Just clean your EGR valve and IACV with carb. cleaner before you go and drive your car on the freeway right before to heat the cat. up.

Stickers.

LOL

P&P?

[johnnyo032003]

aftermarket wise id be happy with the I/H/E, the h23 IM, and shot of nitrous. thatll get me to be able to stick with the civics and tegs to get down the track.

u can't do that already off of engine torque alone? i eat si civics for breakfast with a stage 1 clutch intake and exhaust on my f22

[deevergote]

The F22 parts will DEFINITELY pass smog if nothing is wrong. The H23 parts MIGHT cause an issue, but possibly not. I wouldn't think so. Nothing listed above, obviously, is a wild race part!


As for aftermarket cats... none really do much in terms of performance. If you want aftermarket, get Carsound or SMSP (www.sms-products.com). As long as the cat doesn't create a significant bottleneck in the system, it shouldn't disrupt flow too much. If you widen the F22A4 collector and get a 2.5" exhaust as owequitit mentioned, THEN the stock cat would probably be too small, and cause a loss of power. As long as you retain the stock exhaust piping, or at least similar... you won't need bigger.

I will go out on a limb and say yes, I never had to do smog so my knowledge is really limited, BUT if you stick to OEM parts and everything else on the motor is tight enough to pass smog, you should have no trouble.

Now if you start with a motor that desperately needs a tune up, leaks oil like a sieve, has a worthless cat, etc, this isn't gonna make things better.

My first cb, my 90 was always that kind of car that felt like it was held together with baling wire and duct tape, because I was a much worse mechanic.

But the knowledge I gained from that shows in the 93 I drive now, and I'll make the bold claim that my car is pretty tip top.

ok so u said maybe u could get by with the stock cat...what aftermarket cat would u recommend? is there that much of a differance?

[b3nsonx]

if i do all of this, will i still pass smog?

[deevergote]

i have a f22a4 in my 1993 se
would all of this ...

"F22A6 camshaft - $25 (92-93 Accord EX)
F22A6 ECU - $25
H23A1 intake manifold and throttle body (from a Prelude SI, 92-96 I believe) - $45
F22A6 IAB "black box" (to be able to activate the secondary runners, the intake air bypass, in the H23 manifold) - no price listed... probably $10 or so...."

work with my car
cuz that would be sweet

Why do you have an A4 in your 93 SE? That should have an A6! The A4 is technically illegal in that car, since it's an older motor than the car it's in!




As for the A6 guys, the A4 header will give you about 5hp most likely, and the H23 IM/TB, as said, will be an upgrade. The impressive 30hp claim is only for the F22A1. It'd be about 25hp on an A4, and 15 or so on an A6. The final outcome is still the same, you just have the parts already It'd cost you a bit less as well!

[accordaffair]

Some people will sell them for as much as $100, don't spend that much though. I did once, out of desperation, and the ecu never really worked 100% anyway. Just keep scoping out a junkyard until you find a good PT6 ecu, and don't let them rip you off. Its better if they don't realize its an ECU, because they will try to rip you off realizing that they are a fortune brand new.

F22A6 ECU - $25

i will keep that in mind when i am swapping my transmission

[accordaffair]

I have an EX, its helpful because you don't have to do as much work as others, namely the wiring for the IAB's, but also the O2 sensor, and the different ECU.

It still takes some work to put in the H23 IM/TB, but its close enough to a direct bolt in.

[Shadow1]

i got a question then
everybody talks out the A4 and the A1

BUT WHAT BOUT THE A6

im pretty sure there are a lot of EX owners that want some action
but remeber we have all that

well all i can tell you is to swap out your a6 IM and put in a h23 IM. either that or swap in a h23 or h22 and give me your f22a6
