More horsepower!

[Kinked210]

I was wondering what all I can do to my D16Z6 for more horsepower....

I just ordered intake, header, and catback exhaust from a local shop...After I do all that, I'm planning to install a new intake manifold...

All this will give me at least 25 extra hp right?

What else can I do for more horsepower besides a swap or FI?

I plan to swap in a B16/18 later on and maybe go turbo...but thats in a couple years...

you could go with some lightweight pulleys. replace them all except for the pulley for the alternator. I also think that one of the best mods for a VTEC motor is to get it a more aggresive cam. You don't want to get one that is too aggressive cause you'll need to do some major head work then. But I think Skunk2 manufactures a streetable cam that requires little head work if any if i'm thinking right.

You'll be lucky to gain 20HP max at the wheels with I/H/E/IM under perfect conditions. If it were my car, I'd start by doing head work.

IMO, if your planning on a swap, stop throwing money @ your current engine & start saving for the new engine. Invest money into suspension since it's one mod that actually does something for the money.

You wont be getting 15 WHP from those mods on a d-series no way in hell...from your mods youll probably get 8-10 WHP around 13-15 horspower at the crank, what they announce. So if you have 125 hp now youll be around 133.

I'm planning on a swap that's why I was wondering if there was anything else I could do to increase hp without actually messing with the block itself...

The I/H/E/IM that I put on my D16 would fit a B16 wouldnt it?

Thanks anyway...

[Kinked210]

So even though the people selling them say they will increase x amount of hp...it wont?

Like the IM i was looking at said 10-15 hp gain...and the others were like 5-7....

[Kinked210]

So do you all reccomend swapping in a B16...or just getting some head work?

According to that MMR site...the headwork will help more than a swap....for less money.

What should I do?

no it wont fit a B16

yah, nothing that fits on a D-series motor will fit on a B-series motor that I know of. If you were looking to swap parts, I suggest you send the parts you bought already back and start saving.

Some intakes might fit a B series manifold. No header from a D series will fit a B series. Exhaust--muffler and piping no problem, as they'll fit. Internals--no go for cams. B and D series cams are different.

Well, if you are planning to fully build the d and not swap, then the head package makes sense. If you still intend to swap later, then save your money and put it towrds the swap.

oh yah, keep your exhaust, it's not dependent on what motor you have, just what chassis your car is.

You see, it's sad when you 'trick your ride out' and you're pushin' 125hp at the wheels..ya' know? It should be some sort of crime...but anyway I agree with the guy who said SAVE YOUR MONEY and quit throwing it into a D series engine! I mean come on now you're going to be competing with Kias and Suzukis on the track with that little bit of HP.

I suggested to him that is he wants a swap, save the money and don't spend it on the D. However, you can get power out of a D. Granted, most people can't extract as much power from a SOHC D-series as a DOHC B-series. But if he doesn't want to swap, a D can be built up. That's why I suggested he decide the route he wants to take BEFORE he spends money. For example, if he wants to sleeve and build a D-series, he can build the motor to handle the boost of for 250hp if he wants. Granted, it will cost some $$, but that;s good power. Espeically in a lightweight car. Now the ceiling he can reach for max power may be more for him in general with the B-series, since it is a better platform (more power) to start out with. The point is, you CAN build a D-series up. It's the same principle as building a b-series or any other motor up. It just takes money.

[dampachi]

Yeah, the way I said it was kind of looking down on the D-series..but it's true you can get power out of them..but I had in mind that he wanted the swap so it's kind of dumb to put money into what you got if you're plaining on ditching that engine anyway.
