Just trying to help one of my buddies.
He has a b20vtec (b16a gen 1 head + b20b block - both USDM) I know this isnt the best swap to boost but hey...
He is running 5.83 lb spring in his wastegate with a t3 turbo...everything was installed corectly to my knowledge. No leaks and idlesfine.
He is also running stock injectors(240cc crap) with an unkown FMU 10:1 ratio
It runs like azz... cant even feel the boost but the BOV is nice (Blitz)
I told him to get some DSM 450 injectors or to use his 92-95 prelude injectors to get him by with a Uber/Crome prog.
He does have a AFC (apexi) controller

What tips you got for this guy... what can he do for now? Its the FMU isnt it.

Thanks

 

change the injectors and run the afc hack. but without the vafc, there won't be the hi cam maps.
so it might be best to get the ecu chipped.
ditching the fmu either way.
what fuel pump is he running?
