intake manifold question

[civic97hx]

so what would u suggest?

so what would u suggest?

like mentioned before, it depends on what you are willing to spend, what your hp/tq goals are, and if you want to go n/a or FI.

you just stating that you want a little more isnt enough. what i consider a little more is 40-50 whp. what you consider a little more may be only 10-20whp.

and as for as down time, ive seen cars going from n/a to turbo in one day. and i know of daily driven turbod hondas.

well yea id say somewhere between 30-40, i dont wanna go cheap with everything but it doesnt have to be top of the line either but thats why i was gonna get all the parts i needed together first then tear her apart and start all over so i dont have to fork it all out at once, just get the stuff i need when i find good deals and have the cash

So, IMO. Just leave the intake alone. Save up a little money for a full motor swap.

^I think your question was answered at the beginning of this thread.^

If your not worried about ever registering your car again, then buy all means, swap intakes. But remember, to use a D16Z6, D16Y8, Edelbrock, blah, blah, blah, you need to change ECUs so that the car doesn't recognize that the EGR is missing. Then once you've changed ECU's, you need to swap cylinder heads because the car won't operate VTEC correctly. At this point, you just paid over $400 to gain maybe 9 hp to the crankshaft. Then, remember that ridiculously huge throttle body, well you just lost power having that on the car. And remember that the piston in the D16Y5 gives the motor .2 compression points less then the D16Y8...

From what your saying you sound like your wanting a B16A swap.

the y5 has vtec only on the exhaust side. y8 and z6 engines have vtec on the intake side. and seeing the y8 is rated at roughly a whopping 10 more hp, doing a mini me with a y8 head would be pointless.

Uhh, since when did the Y5/Y8/Z6's have two cams LOL Heres what VTEC-E actually is... (Taken from Wikipedia)

"At low RPM, one of the two intake valves is only allowed to open a very small amount, increasing the fuel/air atomization in the cylinder and thus allowing a leaner mixture to be used. As the engine's speed increases, both valves are needed to supply sufficient mixture. A sliding pin, which is pressured by oil, as in the regular VTEC, is used to connect both valves together and allows the full opening of the second valve."

Yes, lets go...

As popularity and marketing value of the VTEC system grew, Honda applied the system to SOHC engines, which shares a common camshaft for both intake and exhaust valves. The trade-off is that SOHC engines only benefit from the VTEC mechanism on the intake valves. This is because VTEC requires a third center rocker arm and cam lobe (for each intake and exhaust side), and in the SOHC engine, the spark plugs are situated between the two exhaust rocker arms, leaving no room for the VTEC rocker arm. Additionally, the center lobe on the camshaft can only be utilized by either the intake or the exhaust, limiting the VTEC feature to one side.

The way you worded your post would lead someone to think that your talking about a DOHC motor. NO SOHC VTEC MOTOR HAS VTEC ON THE EXHAUST SIDE. That was my point.

so i guess its starting to sound like a swap would be my best bet, well now i guess im off to search about doin a swap... is it the b16a thats in the 99-00 si?

[Spork]

b16's are worthless in my opinion (and I have owned a couple, so I'm speaking from experience), if you are going to swap it, put something in that will have better numbers. I would recommend at least a GSR motor (B18c) to start with.
