HondaCivic4358 · #1 05-28-2005, 01:12 PM

me and my friend are racing next weekend. i am getting pretty damn excited, i was looking for specs on my car and his car. it said a crx si had a quarter mile time of 16.4, stock that it. i have a z6 but the vtecs not hooked up yet DAMMIT!!!! with i/h/e. he has a stock 944 non-turbo. i was looking for the quarter mile time of his car and go figure....16.4 stock, which it is. im guessing i might take this one. goddammit i wish my vtec was hooked up right about now

if u put money on it who do u think would win?

...The better driver.

Vtec wont matter, if you drive well you should take this one home.

Man the vtec will engage with a 12v source, just rig a toggle switch up just for the race. i feel a difference with vtec or not on my little z6! every bit makes a difference! truthfully u will take him with or without!! is he auto or manual?

hes manual too. how would i rig it up? and when i hit the switch at say 5000, (just an example), and i shift, would i turn it off and hit it again? or just leave it on till im done?

If he's a better driver the 944 will own you...

Trust me I know from experience. I had a 1985.5 944 N/A with intake and full 2.5" exhaust, lots of good parts that put a hole in my pocket and I could waste many domestics and ricers in it...

I dunno though, my little Si is pretty quick. It almost feels the same sometimes only the power is pulling me instead of pushing me. When I had high compression pistons it was a no brainer though... CRX all the way.... hook up the vtec and slip the clutch to get traction...

hook up the vtec....lol.....sounds easy enough, but when ur 16, and u have no money its very difficult. do u think it will hurt to run it with a toggleswitch until i get money to pay for ecu and harness adapter? i will only use it when im racing, or can i burn up the solenoid by doing this?

AND how do i use it once i get the toggleswitch hooked up? just hit it at the desired rpm, then when i shift turn it off, then hit it again at the desired rpm? or just leave it on?

just leave it on, when youre racing you dont leave vtec bc ur rpms dont drop that much when u shift. After you hit it just leave it on until you pass the 1/4 mile line.

I had a z6 in my crx with the vafc that could activate it at a certain rpm. Then when we put that motor in a hatch, we didn't even bother to hook the vafc up, and it felt faster. So I donno about vtec in SOHC motors.

I agree with slowCRX-better driver..

For later vtec activation though, they sell something on ebay called a "rpm window switch"

http://cgi.ebay.com/ebaymotors/ws/eB...spagename=WDVW

That will work for vtec activation.

well, in order for vtec to operate at its highest level, doesnt the fuel pressure and oil pressure change, and not just timing advance? isnt this why people do the p28 swap? if all you guys are saying is in order to operate my vtec properly, i can just use an rpm activated switch? but i thought that in order to get the full effect, u need the p28 because it has the correct fuel settings when vtec kicks in. im so confused. will i get the same effect if i just hook an rpn activated switch up to it, rather than having to spend 150 on and ecu and 100 on a wiring harness converter?

Do you have the 4 wire O2 sensor yet? I was just wondering because somebody mentioned that you can use a p08 or whatever the ecu is for a jdm d15 vtec that uses a 1 wire ecu, but you still have to wire in vtec and it run lean cuz it's not the same displacement. Anyway, do it right get a vafc or use the correct ecu. You need the correct amount of fuel when the cam is in high lift mode.

You can use a switch to turn it on and the cam will lift. I read how it worked a long time ago and there is like a metal dow pin that pushes a mechanism that activates the cam lobe or whatever to lift. Anyway, I've heard stories of mini-me swaps overheating and all kinds of stuff from ghetto rigging vtec. I've also seen a vtec video... "Best Motoring: The Battle to 10k RPM"... where one of the cars highlighted has vtec cams that are in permanent vtec mode. I always assumed it was like a wild comp cam or something like I have. I just hate to see people spend lots of hard earned cash to go and just fuck it up...

Yeah i tried that perm vtec mode.. does nothing but stall ur car out. I once had a toggle hooked up, would launch at 4800 with it on and left it on all good in the hood! but i invested $150 into a NIB vtec controller off ebay and got my car tuned for $100 and felt a difference! as i meantioned b4 every lil bit makes a diff when ur working with a sohc. The RPM activated switch works but it go on ebay and get urself a spoon/apexi/w.e cheap vtec controller u can get and be proud it isnt ghetto rigged like a toggle or w.e u can get that isnt intended for vtec activation

HondaCivic4358 · #14 06-01-2005, 06:56 PM

does it have to be apexi or fields or spoon? i mean who seriously wants to pay 200-300 for one? i guess if u have the money, u would think differently, but i just need something to get me by for about 1-2 months. what im saying is, will i hurt my solenoid or engine by just using an rpm activated switch just for now? ive heard of people burning up there solenoids, i just dont know how. this rpm switch thing would be for a maximum of 3 months, not like an all-the-time thing. and i wouldnt "get on it" all the time.

FuLL BLown STD · #15 06-01-2005, 07:05 PM

No seriously a RPM switch will work fine.. alot better inmy opinion then a toggle switch.. but ur prices of $200-300 are a little off. u can find vtec controllers cheaper than that. just gotta look uh around uh little. my local parts store sold msd act switch for $74 and i said screw it ill get myself a vtec controller with air/fuel management for a few bucks more and get it tuned for my applications. made a mild increase.. maybe not enuff to impress sum1 willing to pay that $60-80 for a switch but it satisfied me.. especially for my future swap. just get urself a switch man you'll be fine with that. every1 got different preferences and opinions about shit
