I remove all things inside of throttle body, just stay the outside body... just to grab the intake pipe...
About fuel pump, 1º i remove the mechanical fuel pump a and add a BMW 4 bar electric fuel pump.... it self, gives more power
Then i remove the throttle diafragm inside pump, and make a custom throttle system, to accelerate directly form the throttle pedal... i can take a picture...
Then i add lot of debit of injection to have more exhaust pressure...
the only problem is the compression ratio, its blow with heat gastket, so now i buy a Sd23 head gasket, is more thick and its full steel...
brand new stock gasket
and new one
sorry my bad english
