well my h22 swap is complete, but there are some problems...with the IAB control solenoid valve installed the car will go for a bit, but on stop and go the car struggles to move, with it not installed the car will go fine, but if you give it too much gas it struggles to go. anybody have any ideas to get my car running normal? thanks in advance

 

Sounds odd to me, first off I would recheck all vacuum lines, and make sure they go to the right spots. Do you have a stock intake or aftermarket? if stock and vacuum lines are wierd it could also keep the intake resonator box from working properly to allow air into the engine? Also Check timing and that all your plug wires are set right. Thats my basic ideas.

 

i have the jdm type-s intake, thanks for the input

 

bump
this is the thing thats confusing me

according to the helms manual its the, intake air bypass control solenoid valve, it the jdm h22 didnt come with it so im using the one off my h23.
am i on the right path or am i way off?
i checked the plugs and the timming was said to be right when i installed the motor. and i checked with my helms manual to make sure all teh vacum lines are right

 

You don't need, just plug the port on the IM. As far as your struggling on take off, do a Tune-Up

 

You don't need the intake selonoid, if you have a intake installed on your car. Just plug up the nipple on the intake manifold.

 

just a side note, I have been running my car without that for oh 8 months now, its been fine, but I do want it for mtn driving mainly, so if you don't wanna run yours, pm me and ill take it off your hands!

 

thanks for teh quick replies guys i'll work on that tune-up asap

 

Do you have that thing plugged into the intake air temperature sensor maybe? The connectors are the same and near each other. If you have the IAB wire hooked to the IAT sensor, the sensor may be fried.

 

i would get rid of the iabs "butterflys" all together ive done this on my gsr and jdm h22 all u have 2 do is take the diaphram vaccum line and plug it to a direct vaccum source itll set a code but does not hurt i personally believe that both cars performed better this way....

That will kill your low-end power dude....it's proven, but in the end it is personal preference.

 

yes its proven on stock motors to kill take off but when you alow the car 2 breath better with an intake and full exhaust u really dont feel a difference i like the butterflys being open at all times ive used jdm intake manis dont know if that would make a difference but from personal experience i believe its beter other people otherwise...

It will have the same effect with an intake and exhaust, man. An intake does next to nothing at all, and a full exhaust would have no effect on the intake manifold...though it could make up for a loss in low-end power depanding on the setup...

Airflow goes like this: smaller passages provide more velocity at lower rpms but will not provide enough flow at higher rpms, while bigger passages make for lower velocity at low rpms but allow more air to enter the chambers at high rpms. The IAB system is good for most eveything but high-end NA builds and turbo setups, not bolt-on cars.
