:pat: Sorry guys, I didn't notice that part.

Free mods, well not really any. Like I said above, you can make a CAI for about $20 or so. That's about all I can think of..

The problem is with Honda's is that they have no torque, so if you were to hack off your muffler, you will see a small gain in horsepower, but a small gain in high horsepower.

okay, i feel a little bad for you... i used to have 1.6 sohc vtec in my 94 ex.. as far as free upgrades..

-advance ignition timing 2-4 degrees, should help the throttle response a bit
-cut the bottom of the airbox, well if you dont have an intake...
-gut the cat... be careful its illegal!
-valve adjustment, maybe even try a tighter valve lash..
-smooth out intake/exhaust manifold or maybe gasket match them..
-
after all that labor, you might gain 5hp max... you might wanna try swapping parts like using a large throttle body from the 1.8 integras, might help a bit also.. good luck

I am very familar with the D-series engines. Let me offer some advice:

Your best bet is to swap an engine in. Preferably a B-series and if you are crazy an H-series. I say this because you will end up spending the same amount of money trying to make the D16 fast - trust me.

I had a 95 Civic SI. Bone stock I ran a 16.8 @ 87 MPH. I put every mod into it I could find - and only the best. AEM CAI, Gude Cam/ECU, MSD ignition, Tanabe Exhaust, JG TB, 8mm wires, dumped about 120lbs, removed the AC and PS belts, lowered it the right way, Nitto drag radials, etc. I got it down to a 15.1 @ 92.9 MPH. But here is the kicker, I dropped about $3500 to do all that (and more little things that didn't work).

That is WELL over the price to drop in a B16 or B18C. Heck, you could do a B18B/B18C (Frankenstein swap) for that much.

So please, consider the swap route. If your D16 is decent, you could get about $400 for that on ebay.

Let me know if you have any other questions.

Later!

yep, that would be the most cost effective move id recommend going with the b18c, nowadays, you'd be hard pressed to find a complete swap for 3500 ... hey 96runner did you used to have a webpage with your si on it? those sohc motors have potential, but its just cheaper to swap... although i did wanna build a d16z6 that could beat those pesky gs-r's...

Buy a 1st gen AWD DSM and run high 14s with "free" mods. (remove a few restrictions in the intake plus a plastic sleeve removed in the boost selonoid was good for 2 more psi of boost.

But then again a Honda has build quality and reliability on it's side;DSMs aren't for everyone.

blob,

looks like your free HP mod options are pretty limited. just cave in, trade in the civic (i had two), buy a 4runner and join the club. you'll be a much happier person and probably wont get as many speeding tickets too

I had a friend that put a couple pics up of my SI on his webpage. But no, I did have anything official. I might be able to dig up some old pics of it – nothing fancy, I liked the sleeper look. In fact, I ran the stock wheels.

I actually beat a couple GSR’s. I also beat a Type-R one time. I ran a 15.3 and he ran a 15.4. Not sure what happened to him, but he lost! I weighed my SI one time, and with me in it, it was 2300, and I weighed 185 back then. I could really get people off the line, but most forced induction cars or V8’s would catch me on the top end.

I had the rev limit set at 8200 on my MSD. You should have heard that thing when I ran an open header at the track. It sounded like a chainsaw on steroids.

Once you get to a certain N/A HP level, VTEC and dual cams don’t mean anything. In fact, a lot of the really fast all-motor guys run SOHC non-VTEC motors. It’s all in the head baby. That’s where I fell short. No headwork.

Boy that's the truth. My brother had a Starion for a while. It was great fun to drive, WHEN it ran correctly, which was rare. Major PITA to work on too.

Still wouldn't mind having an AWD Eclipse/Talon tho. Excellent potential.

Agreed, I never really screwed with those - unless they were stock, and even then it was a good race. I could nail them off the line pretty good unless it was a good driver or raining...then I would usually get toasted.

The best thing to do for a D16y8 is turbo/Supercharge it. Your not going to get any power out of it for free.

You should add "significant" free power in your post. I garantee I can squeeze some ponies out of it by removing the intake resonators, sawwing off the muffler, advancing the timing, and removing the PS and AC belts. All that is free except the timing advance, which would require premium fuel. Add all that up and you could be in the 5 - 10 HP range. Watch out Mustangs!!
