I recently rebuilt and installed my jdm b16a into my 90 crx. I have about 1000 miles now and now that my breakin period is about over and ive started pushing the gas a bit harder im not feeling the power that should be there. The power feels closer to the stock d16 or maybe even a little less. Theres nothing leaking from the engine, i replaced most all seals and gaskets and new rings, bearings, etc. Not smoking either. But the power just doesnt seem to be there. Its getting good spark and im installing my fpr tomorrow. My fuel pressure is at 30 psi right now. What should i up it to? Motor has i/h/e and light flywheel. Also i found out that my vtec isnt working and it throws the vtec pressure switch code 22 when it trys to engage. What is causing that and how to fix it? What should i do?! TIA

 

Well... FUEL INJECTION SYSTEMS need at least 45 PSI to run correctly.... so try that and get back to me...

 

well if your Vtec isn't working, its obviously not going to be faster.

 

Never said i needed vtec to be fast. But the check engine light beaming your eyes everytime you hit 5 grand would annoy you too. And im not really looking for comments like these when all im trying to do is make my car and engine function correctly. So if you dont mind please post your non-helpful comments elsewhere.

 

vtec adds roughly 30 hp. a tremendous increase in power. i used to run no vtec and i would wonder why i wouldnt beat an EX by much. but now i have vtec activated by a pushbutton on my shifter. It's like a 30 shot

 

45 psi of fuel will fix it.

 

UM if you want your engine to function correctly, you need to fix your vtec.

you wonder why it feels like a d16? because there is NO VTEC.
it has the same horsepower as the d16 without vtec.

and your fuel pressure is low.

 

without v-tec ur not gonna be any faster than a zc so fix that and u should be close to where u wanna be.

 

Also, you might try replacing your fuel pressure regulator. 30PSI is seriously low for ANY Honda motor and can cause it to run dangerously lean. By the way a check engine light for VTEC codes is flashed at ALL RPMs. Not just above the VTEC switchover point.

 

So what should i check then because i only get a check engine light when its hit the same spot in the rpms everytime? its the code for the pressure switch not the solenoid.

This can't be true, can it? The vtec cars ive riden in do not feel near a 30hp gain when engaged. But i could be wrong.

 

no offense dude, but you just sound like some ricer that doesnt know what he is saying. Vtec's main purpose is to allow the engine to run efficiently at high rpms (not consume large quantities of gas.)

 

you must be riding in some fucked up cars then. in my cx w/b16, ctr pistons, and gsr head, it would start breaking the tires loose when vtec engaged in 2nd gear. i would get pulled by z6's until i hit vtec, then i'd just roar by.

i could bake em off at 35 mph w/vtec. thats the whole point of a b16...vtec

edit: grammar and spelling owns me

that is not true.
yes vtec adds about 35hp, I got the unforutionate opportunity to dyno my b16 without vtec, it was 111hp, with vtec it was 147.

as for your pushbutton, your retarded. and you sound like a stunna. just wire it to the ecu like it should be run.

 

this was in a 99 civic si w/header, intake and exhaust. The sound was good but it just didnt feel much more than that. Like i said tho i could have been wrong.

 

But did you ride in it without vtec? That is a 2500lb car not a 2000lb EF with a B16.

Go check all your wires. Did you wire in the vtec? You need to do that first before you can judge how fast your car really is. Right now it's not running at 100%.

 

Another thing you may want to do is change your fuel filter. This can make a hell of a difference if it hasn't been changed in a while and is clogged up. It did on my car.

 

it was the b16a2 civic i believe, and im still learning car **** same as everybody so banned i agree with kamin and incubus on

&
so dont call me a fool.

 

You can feel it!... I think? (and that is from experience)

 

All you ******** need to get off black90b16a's ***. He came on here with honest and genuine questions.......questions that most of you didn't know how to answer, so when he said he didnt know vtec added 30 hp, all you ******* jumped on that as your opp to cover up the fact that when it comes to what your all saying, its complete utter bullshit. Kamin was the ONLY person to offer usefull information. The thing you ******* don't realize is that IF you continue on with your love of cars and you look back at yourself 10 years from this day, every 10 years youll realize you didn't know ****. So try and at least be nice while you wade through the pond of childs youth, or just don't post.

 

props to slimer89 too, changing the fuel filter is vital to top performance.

 

Hey I tried to help

 

Thank you
i try to add information before/after i flame people (not black90b16, i was talking about banned)

sorry if i came off as flaming, that was not my intention

i was just pointing out thta the whole point of a b16 is vtec. its a small displacement, no torque motor. all it's good for is screaming up top, and that my friends, it does very well. without vtec though, you loose this. the small lobes arent meant to make any power above something like 5 grand, therefore, you are raped of your topend if vtec isnt hooked up

 

as far as i know vtec will not kick in if a.) not enough oil, or b.) not enough oil pressure. I would start with those things 1st. otherwise make sure that you wired teh solenoid up & correctly & that it's working at 100%. that's my $.02

 

i didnt really take it as flaming from you skud, i just didnt really feel alot of power when the civic engaged. It could have been something wrong with it tho. But thats why i asked. anyways. I got my fpr installed and uped the pressure to 45 and yes now there is a noticeable difference. Thanks for that help. Now im gonna work on vtec and get that going. Ill let yall know what happens.
