exaust return

[dave the brave]

Hi all
my engine 2.5 DI has a return feed from the exhaust to the air manifold.(banana) type air intake.
is this used to enhance performance or to reduce emissions ?
& if it was removed could a turbo be fitted to this engine ?

hi dave its for your emisions ,i have herd of poeple blocking this off and sometimes it gives more performance, !but no your turbo would not fit in that place !

[dave the brave]

thanks Mark
is this engine a 75hp or 90 hp as i have been told the engines with the (banana) intake are more powerful ?

[madmark]

dave she could be 70ps or 76ps or if you are lucky in a long wheelbase around 1993-94 80ps , no 90ps as turbos, were 85ps and 100ps and rare as old boots 115ps!

blank off the vac pipes to the exhuast gas recirculating valve, its only filling your manifold and inlet ports full of soot
