Engine is a b16, I originally wanted to get a 4-1 to play to the engines strengths, but saw a good deal on a hytech replica and was wondering if it would give me just as much help at high rpms as the DC would. Do the replica's perform well?

the hytech tri-y and many variations of it make good power throughout the powerband

more power than a dc 4-1 at high rpms?

goldegg

More than likly yes.

there is no hytech replica for d series. you'll need a custom hytech.

laxbuddy48

ah i see. thanks .

Don't mean to burst your bubble but neither is going to show a too noticeably different gain. A header only rarely sees large gains of any amount, especially if its the only modification (adding modifications makes existing modifications more noticeable).

How much HP would i gain by using Hytech replica on almost stock B16A2, only skunk2 intake manifold, CAI and an ACT flywheel are fitted.

dizzzane

I'd be surprised if you saw +5 HP on a real graph.

as previously stated, a header is only a part of a SYSTEM that must work together efficiently to make power.

I plan to do the basic stuff first, header and 2.25 full exhaust back.

Wanting to see near 180hp

dizzzane

Firstly i would suggest getting atleast a 60mm exhaust (2.38 inches), it will suit you much better than 2.5, although i would go 3in if you were planning on going over 200 whp naturally aspirated.

Secondly, with mild bolt-on's like you stated, you will be hard pressed to see the 180hp mark. My type r with i/h/e msd wires/ngk plugs and no ps or ac made only 185 on a p28 ecu..... don't shoot to high, you will only be dissapointed when you don't reach your goals.

you picked the worst platform for a NA build

dizzzane

Researching your build will pay large dividends in the future.

Amen, getting a b16 will take a lot more than bolt ons with a decent header to make 180whp.

You're looking at some $800 cams, dyno time, and a good head job to make things easy.

All of which will cost you ~$1500-1800 if done cheaply.

If you're sticking with the b16, stroke it, or slap a b18c or better yet a b20 bottom end on it.

Hypothetically if you went this route: Just the b20 bottom and a vtec conversion will get you impressive numbers. Maybe not 180whp, but it will have exponentially more torque and thus be faster from the middle range.

what do you guys think of vibrant headers?

ru7

Well about NA build, not much of a choice, can only import B18c (and such) from USA, so much $$$ is needed.

I hope to push 180 since my car was dynoed with ex owner at 171 hp. I wont feel bad if it doesnt hit the mark, just want to get close. All the parts need to be "imported" to Slovenia (no stuff for Hondas where we live) so all parts are pretty expensive. Basic mods is all i can afford for now

Tnx for info guys.

EDIT: B16 makes 160 HP stock, so 180 is easy reachable i think :S Or not?

you will notice a considerable gain with the Hytech, it's comparable to using an x-pipe on a mustang instead of an h-pipe.

a gsr motor makes what 10 more ft. lbs. of torque and 10 more horsepower for an extra $1200 hold on while i bow to it's unprecendentedness.

get an LS bottom end for next to nothing and that "worthless B16" becomes an LS/V and still costs lest than any other b-series motor, save of course for just a straight up LS

those are crank numbers. 160hp is ~135whp.

you dont have to rev the **** out of a b18c1 to feel something

ru7

Haha, that was bothering me, i wasnt talking WHP )))

I meant 180 on the crank

Vibrant headers anyone?
