Hey im new to this forum and lately ive always found information that i needed here on HMT. So for the people that run it...Props to you guys.

Anyways i have a 92 integra RS with a b20b in it and im having a few issues with my car lately. I wanted to resolve these problems before i install the turbo kit i have ready to go.

First issue is a hesitation issue that happens at slight throttle that happens every now and then at any rpm range. It feels like the motor is holding back and a second later i have power. It also happens when i am on part throttle steady cruising then i put press on the gas alittle more suddenly. i just cant pin point what can be the problem. When this hesitation does happen i can hear the muffler sputter and spit. This type of thing happens alittle more often when it is cold out. Any advise would help me out alot thanks.

Second i have an issue with the whole car vibrating under 60kph and i have only vibration in the wheel at 100kph. The 20-60 vibration feels likes its coming from the front of my car. If i cruise slowly to 60 it doesnt happen but when i give just alittle more gas from 20-60 the whole car vibrates hardcore. Can the mounts be crapping out on me or is it something else. i did fill two of the mounts (front tranny and passenger side) with urathane so the other 2 mounts could be the culprit. I just need more opinions before i start dishing out cash to fix it.


here are more info on the car that might or might not help find a solution to either or problem
it might not help but the b20 has 120k on it but the rest of the parts like the alternator, starter, distributer, plugwires, and o2 sensor are all obd1 and come from the stock b18a i had swapped out. i kept the stock tranny but put a 6 puck unsprung clutch in it. I just had the driver side axle replaced since the old one was ripped to ----. the tires on my car have been balanced recently. I have not yet gotten an alignment since i want to get a camber kit first.

Thanks once again in advanced...im desparate to get these issues resolved. I cant stand driving an uncomfortable car.

in terms of hesitating, check the throttle cable... also what engine management are you using?

vibrationwise, the fact that you have filled half of the motor mounts might the problem. Try filling all of them. Did you balance all of your tires? Did you get an alignment? How does the motor sound when its idleing... does it sound funny?

levan634

not running any engine management. Stock b18 ecu running. It was hesitating before the swap aswell. I havent gotten an alignment like i said earlier. the motor sounds fine when its idling.

actually at idle the rpms jumps up to maybe 750 for a second then drops below 500rpm and bogs for a second. Fack i have lots of problems haha....please help

in terms of checking the throttle cable...what am i exactly checking for. The throttle cable is not loose. keep the suggestions coming

try to get a chipped ecu. realize that your engine is no longer a 1.8L but is a 2.0L and will require more fuel either way.

Check all the maintenance stuff. Yes check if the throttle cable is loose. Check plugs etc.

levan634

throttle cable is tight. i have a chipped p28 but im gonna use it to tune the turbo application. plugs are relatively new. Timing is on. valves have been recently adjusted. i have an adjustable fuel pressure regulator and i bumped up the fuel pressure. Fuel should be fine....like i said it did this even with the b18

have you checked your catalytic converter?

levan634

i dont have one....sorry i forgot to add that......

djfob

throwing any codes at all?

Guy-Fast

What did you use from the b18 over to the b20. I say the cap/rotor may be your isse

levan634

not throwing any codes at all. Cap and rotor are brand new.
