Hi all!
to begin excuse my English, I'm from chile and I have a problem that is driving me crazy ... :ohno: :ohno:
I have a onevia year 93 original engine KA24DE, and made him swap SR20DET Black top s14, apparently this was automatic, but buy the swap from Japan and this has a manual transmission and all referring to manual, I guess that was transformed from Japan but it maintains the ecu and tps automatic ...
that is finished installing all the intercooler and BOV system, and have a problem that bothers me the full engine speed, going from 4000-5000 rpms there is a lag pretty and the engine tends to stomp even limited .. . But to accelerate gradually there is no problem ...
I constantly checked for leaks, even check the timming, but everything is in order ... on the 5000+ rpm, the engine is working properly, and pressure ranges 0.4 bar or slightly less
Currently I have mounted an intercooler Blitz and Blitz BOV
Stock SR20DET Black Top

I hope someone can help me with this
Greetings!

Maybe your wastegate isn't shut all the way?
It should look like this:

You should be able to remove that rod from the arm, and make sure it is completely closed (towards the wastegate actuator).
