hi guys

feel a bit stupid asking but

i am almost ready to start the engine on the mk2 escort fitted with a cosworth 4wd engine converted to 2wd ie sump has been changed to 2wd big wing sump.

anyway

i am running
4wd t3 turbo
rs500 intercooler
rainbird plenum
bailey breather
big winged gated baffled sump
3bar map sensor
megasonic dump valve

the only things i havent done is the air filter

when i was talking to someone the other day they was saying i shoud fit a -31 actuator ?????

what do u guys think?

what are the up sides and are there any down sides

many thanks guys
