My hatch has a b20 turbo and my first problem is when i accelerate you can feel it kind of jerking around 3-5 rpm but its not really that bad too where it keeps it from accelerating hard, it bugs me, would it be the ignition?
I don't know how to put this but my other problem is when i'm accelerating hard it sounds like the blow off valve is still open but its not a consistent blowing of air its like the blow off valve is opening and closing really quick while accelerating but once i let off the throttle you do hear the blow off valve let out, i don't know but maybe its just turbo it just seems louder then normal.
And why when i let off the throttle and its still in gear it feels like it jerking while slowing down?
This is my first turbo car btw

 

setup, engine management, etc.

without that info we CANNOT help you at all. you need to give us more info

 

I didn't built it i got it from a friend but from what i can see and tell it has a garrett 52 or 57 trim turbo, i think its a knock off blow off valve, don't know about the injectors beside their aftermarket, the turbo doesn't have a filter on it just a screen ( not enough room to fit a filter or piping on the turbo it almost hits the trans), stock map sensor, hondadata s100 and a stock b20b idk what else to tell you

 

Did your friend have it tuned or base mapped?

 

yeah he brought it to the dyno and had it tuned and its running about 8psi

 

I guess i shouldn't say jerking feeling its more of a shaking type feeling
