A compression test, or a leak down test would be able to tell that.

but if he didnt have the money for a turbo i dont think he is going to have the money to put a k20 in it.

His compression was OK. He posted it in this thread.

Thank you. That makes me feel better. I think the performance of the 2 are very similar. One is newer but heavier, one is older but lighter.

Very good point. I will go from a stop and post what happens.

that intake manifold iwll raise your power band to a higher rpm. and with stock cams your nto making use of it. youll gain a few hp above 6400rpm... or above 7200rpm but you lsoe power everythign below that. the cams arnt makig use of that airflow and you are losign the vacuum efect of a small manifold. put your stock one on check out hte difference?. also the skunk2 is designed for more airflow... so higher rev + bigger cam it makes a great diff. on a stock motor ive heard at times LOSING power because there is no vacuum. its like runnign open header or a 4inch straight pipe on a stock b16</TD></TR></TABLE>

I also thought about the mods like intake manifold and throttle body hurting lowend and helping top end. Could be a possibility.

The motor is not tired. Compression test was strong at 220, 225, 225, 230. As far as questionable driving. It was a pull from 3rd gear into 4th. How can you questionably smash the throttle in third and then do a 3-4 shift?

didnt see the compression test part. my apologies.

then it boils down to no tune, which has been said 54 times already im sure. but you might have other issues. im kinda too tired oafter work to diagnose

"why is my b16 not as fast as that b16"

i would just start with the cheapest thing possible, and ork my way up to the most expensive until i found what was wrong.

jut remember, average dyno tune price is 125 bucks. average gain on a motor like that 10-15 hp. name a part you can buy for 125 bucks that produces 10-15hp gains.

does have a good point.

Did you figure out what the gremlin is or was?

Hey i had a little problem with my car lackin' some power. behind the intake manifold there is this sensor being held by two 12 mm bolts. get some carbrator cleaner and spray it on the screen, might be dirty! Mines was! and spray some on the 2 lil holes in the intake manifold. you will not miss them, if your car doesn't want to turn on after just crank it and give it some gas. try that let me know what results you get.

That's the iacv...wont affect power output..

That would not cause him to loose against a civic though, an intake manifold really will not help him that much.

I think a lot of people are forgetting when cars are rolling on a highway, weight is not put into consideration. </TD></TR></TABLE>

yeah, that bit about weight not being a factor shows a complete and utter misunderstanding of physics.

F = MA..

In general, a stock B16 in a CRx produces mid-high 14s with mid 90 traps. I can NOT believe a 99 Civic Si coupe ran those numbers stock.

There is still something goofy with your setup. I agree with others that the manifold is hurting you.

I'd really consider getting to a dyno to get a look at your baseline HP & Torque curves, and A/F curve.

If you aren't dyno tuning it, I'd toss the cam gears, and run stock, at least you know they'll be accurate then. (with even 1 degree making a difference, I don't trust them to be correct without messing with them on the dyno)

something just seems goofy here.

How about a leak down test then.

agordon

try puting on your stock throttle body, your ecu doesn't know you have a bigger t/b so it's gonna read it wrong if you dont get it dyno tuned

you should be womping on si's my 91 crx si with i/h/e would **** all over si's
