I have an automatic '92 Si. H23 motor.

I am not going to go forced induction. Nitrous undecided.

This is really supposed to be my "cool looking commute car"

If I put in a short air ram, headers, and exhaust am I going to notice any freaking difference? And if I do notice something is it going to be worth the $600+ to add those mods?

I've been reading the forums for hours now, and on intake, headers, and exhaust mods, I have found numerous posts that say "I noticed little to no difference"

Thanks,
Swami

Again, it's up to you if it's worth it. For me, I also have a '92 Si as well. I never thought about it as a race/show car. It's always been my fun car. A daily driver that I have fun driving. Sure I have the I/H/E setup and a few cosmetic mods. I'm happy with it. I haven't spent that much either since eBay is a great friend of mine and also I have friends that can get me parts cheap. How can I forget about the PO.com members that have helped too.
haha...But to answer your question. I have indeed felt a difference in performance. I wouldn't say that it boosted my hp/torque by a whole lot, but I can say that my car runs pretty efficient. I'm happy with the set up.

If you want to save a few bucks, and just want a little more "ooomph" out of the car, then get a DC header, and a custom 2.5inch exhuast. Get a resonator put in there so it doesn't sound like crap. Then just get a nice drop in filter for the intake and remove the intake resonator. Honda intakes are extremely well designed, they flow great, but the stock filter sucks and the resontator is put on as an after thought to keep old people happy. They are also made out of plastics that resist heat-soak. Much better than an aluminum CAI.

good, noticable gains for less than 400$

I had been looking at Greddy Evo or and Apexi N1 exhaust, would that fit the bill?

I had been looking at a short ram, because from what I gathered, they would perform at least as good as stock, plus have some low end gain. True?? They are super cheap, and I think they look cool.

I figured I was going to do the mods anyway, since its not THAT much dough, but was just wondering if anybody would back me up that there is no replacement for cubic inches...

Thanks for the input!

It is true that there is no replacement for displacement when it comes to all out balls (speed) but...and there is a big but.

how many 5.0L cars can handle they way ours do stock? my buddy has a REALLY nice stang GT and its fast as fvck, but when i took a turn in it...it started to slide. and all i could think was "i can go 10mph faster on this turn in my prelude"

and about the mods, i got an H23 w/ I/E and it does pull harder then it did, the intake (short ram) has some pull down low and my apexi N1 pulls consistently throughout i gotta say.

overall with my mods thus far, im quite happy

any other questions Swami?

I really, really appreciate all the input, being such a newb.

I guess I do have one more question, that I couldn't get from searches.

What is preferrable in headers? 4-2-1 or 4-1 or does it makes sense to compare those two designs?

If all I am gonna do is I/H/E does it make any sense to get better plugs? (I think I have new plugs, but haven't checked yet)

Tribotech? Intake Cleaners? Anything else you would do to a car you just bought?

Tranny fluid looks good, but the brakes are a bit mushy.

17" Enkei RS6 rims / Yokohomas are going on today. They have a 38mm offset, but I am probably not going to lower anyway, because I already can't get my head under the car.

Thanks!
Swami

as for the 4-2-1 headers i wouldnt worry about it, as no one makes a 4-1 for the si. just get a good tune up and inspection with honda parts, and you should be good. take care of the car and it will take care of you, i have 151k on my lude and i just started modding it

When I used to have my automatic 92 Si, my best mod was a tranny swap. The $1k I spent in parts (swapped it myself) was very well worth it. Other than that, intake and headers will be your next best mod if you don't swap that auto tranny out.

^^^ he has an NA lude though 2.5" for a header is HUGE

Some Si preludes have dyno'd 14whp more with a nice I/H/E setup over stock #'s, so yeah, I'd say the chance is definately there to notice a nice gain.

scalifludesi, I never even knew you wrecked your h23 man. Sorry to hear that. Have you gotten the vtec lude yet?

i recently got my whole set up goin with my exhaust, header and blah blah. it did give me a noticeable gain, thats for sure. im just wondering how much i would get on a dyno. but then you have to think... if i had a turbo car, with all the money i spent, i could have 60hp+.... so i really dont know if its worth it.

KB798

Hmm...well be sure not to lower your car...because with a 38 offset, I think you might rub with any lowering done.

Yep...there was a thread about it in OT I believe..

So 2.5" is too large for the header pipes if you are NA?

What does too large do? kill torque?

Swami

Preyluder

Creates much more backpressure as well.

bsi

it reduces backpressure, youll lose torque and HP if there is no FI. there is no reason to go that big. 2.5 is what youre exhaust should be.

there is a thread in OT about his accident w/pics, im too tired to search though
