watda Member 40 Member For: 16y 7m 27d Posted 07/10/08 01:14 AM Author Share Posted 07/10/08 01:14 AM Is there any room for a 4" intake that goes under the battery...perhaps a custom job? From what I understand, doesn't the 4" CAI taper into 3" at the turbo anyway Link to comment Share on other sites More sharing options...

SM DJP Member 9 Member For: 16y 2m 21d Gender: Male Location: Noble Park Posted 24/10/08 08:20 AM Share Posted 24/10/08 08:20 AM I'm trying to put together a package of modifications for my BF MKII XR6T that will provide an "easy" 350kw atw and potentially the ability to push the 400 mark.At this stage, the modifications being considered are:Flash box/tuneStage 2 intercooler from PW, Plazmaman or the like, including under battery air intakeSeimens injectors (62 lbs I believe)X force exhaust - 4 inch dump, 3.5 inch cat with twin 2.5inch systemBosch 044 Fuel pump12psi actuator and wastegate 'Flapper" mod.These seem to be the standard upgrades when looking for the 330-350kw atw mark. However what can be done to push this into the higher 300's/low 400's? For example, is an upgrade intake plenum going to help me or is there something else out there?? And is this power possible on 15psi, or is this the power level where internal engine modifications become a necessity?Most importantly the car must:- Produce excellent torque (eg 4th of 5th gear pull at 60km/h should be effortless)- Produce consistent power.Thanks in advance.

Is there anyway to retain the factory battery position and have the larger intake?u can but u need some pipework 2 suit. it will sit comfortably in front of the pwr steer fluid cont.

I ment use a 5" pipe but squash it so it is 3"high and X"wide kind of like the old ef/fl exhaust use to be. If not I might take a day of and see my exhaust mate and have a play.
