i have a b20z with a jdm b20 head...just got a new timing belt put professionally on and the damn engine is not making any power when at normal operating temperature, my dizzy is set at stock timing so i know its not that. it has full power when its cold but when i get on it when its warmed up it lacks power and i have no idea what it could be. if anyone has any suggestions what it might be let me know asap...thanks

 

none of you crazzy honda guys have anything to say or offer about my problem?

 

Whats do you mean " full" power. Could use a tune??

How does your plugs look.

 

timing belt off a tooth?

 

I'd double check my timing mark just to see if they're TDC.

 

head gasket installed properly?

 

full power as in it doesnt make any power going from 2500rpm to 6500rpm when its fully warmed up it just lags and my timing is right i doule checked it three time it was off by two teeth before i got it done right, my spark plugs look great or normal i should say...my p28 ecu is chipped and tuned with a type r porgram that has the vtec disabled on it right now idk if thats what is maken my car run crappy or not. and my head gasket is installed properly.

 

Calibrate TPS possibly?

 

probably has alot to do with it..

Running a tune thats not made for your car, and is made for a 1.8 liter vs your 2.0.

The iat compensations and ect fuel compensations are going to be different..probably a good tune will help your entire problem.

 

I would try another map, I have never used a p73 map for a b20. Ls base is what I prefer

 

Get a tune you idiot.

 

lol

 

haha alright guys i get i am an idiot...i will get a base ls map setup for it tomorrow and go from there. ehhh i wanna get this problem figured out it might be my valves though too. i got them adjusted when my timing was off so that could be my issue right there i will get them adjusted one more time to see whats up with it.

 

Put a stock base map on it! First ...

 

im gunna do tht soon...i really want this engine to pull hard and run normal....i just advanced the timing to see what would happen and now my car wont even stay on...it turns right off so i set it back to where it was and still it wont stay at idle it turns off...idk what to do now

 

haha dumb me i never got the head decked.....so today i blew up my engine, got another b20 going in tomorrow...so def learned my lesson always double chech your stuff before you put the engine back together.....

 

So your hg was installed backwards?

 

nope head gasket was fine....it was my block it was warped and never decked so there was a small gap between the head and block. and on top of that i blew my head gasket also

 

for all you guys who said it was my tune...dead wrong...type R tune didnt have any role in blowing my head gasket or making my car run bad...

 

bringing it back from the dead.....i have this time aorund a new jdm b20b with 32000 miles on it. my timing is right, dead on in fact and the engine has no power at all it doesnt pull like a b20 should. it has a gap in the power band meaning as soon as i get on the gas from 2500rpm to about 5000rpm its just crap. i dont understand why my engine is doing this. im running the usdm crv ecu and all my sensors are new so im at a loss right now, anyone that can help point me in the right direction id be thankful for that. OH and before i redid my timing i noticed that my crank was off by two to three teeth and thats when i decided to redo it. my engine pulled hard then but now with my timing perfect it lacks the power

 

anyone think its time for a new dizzy? even though ive tried two different known working ones? im running out of ideas here...its just getting flat spots in the powerband and i dont know why.

 

I feel dumb reading this thread. Take a picture of you timing marks.

 

did you just say you are using a crv ecu?

 

You located in temecula? heh, you pay me and il fix it. what year honda?

 

yes im in temecula and its a 99 honda civic, and yeah im using a crv ecu
