hello everyone.
my engine is D14A4 turbo'd with crome and 450cc's.
the stock injectors on this engine are 190cc's.

my idle is kinda sloppy with the 450's.

will 240cc's be enough for this engine. ? max hp is 160-170(and i'm optimistic)


thanks

 

If you have the 450's there is no reason to downgrade to 240's. Just work on the tune and it will idle like stock with the 450's.

 

It has to be tuned better 14.7 on the wide band air -fuel ratio is what you want at idle. Do you have a resistor box. If not that could be your problem.
