If you went qauds / individual throttle bodies since you would be running a full ems system, fitment of a mechanical cable for the throttle body woudl be mandatory.
ANytime you do a throttle body upgrade, manifold work is necessary. Our planned 65mm throttle body we do not yet know if it will fit up to the stock manifold without extensive work or only be available with a complete new manifold. Time will tell.
On the outlander 2.4 mivec they run a very very small air flow meter whcih is a large restriction. These are key area's we intend to develop - larger diameter intake piping always improves air flow into the engine.

At this moment its all theoretical. Don't ask me too many technical questions or possible gains until we actually test some products on the car.
BUt be assured the minute we do any testing, we will publish any results immedietly to everyone. Probably have a specific page on our website dedicated to the R&D work on the RA and Outlander vehicles.

This is petty much the greatest thing that ever happened to me, not including the day i purchased my super white ralliart but including the day my son was born. This makes our all motor dreams possible and not a joke N-E more. Out of all the performance parts you guys are developing the cams and especially the Greddy engine management peak my interest the most. All those other parts would mean nothing without the proper tuning. Thanx bro's.
I just hope some good products come out for our car with out the marketing crap end. I'd like to see n/a around 225-250 and once your into turbo thats a whole nother game. optimisticly I wish our car was a high 12s low 13s car (always want faster, but optimisticly)

Well we have some more news on the new lancer engine.
WE have just got our first billet camshaft from mitsubishi to use as our master billet. FIrstly to work out the camshaft stock profile and to use to design our billets.
Intersting news is that I was wrong in one regard. This engine is a true mivec engine not just an advanced cam timing as we first thought.
Where we thought htye were simply advacning / retarding the camsafht timing is incorrect.
They are running a secondary lobe on the intake portion of the camshaft noly which has a higher lift and duration. But on the intake only. The exhaust lobe remains the same profile.
So its a mivec engine, but only half a mivec if that makes sense.
But this is still great news cause it means we can really do something with the camshaft timing now with some very nice profiles as this means we can essentially retain teh stock low rpm intake camshaft profile, improve the exhaust slightly probably half a profile, and then go aroudn 1 full profile larger on the intake high rpm lobes for some very nice large improvements.
And of course - we have a very turbo friendly camshaft design to work wtih as well.
So within the next 6 weeks the first range of Ralliart camshafts will be released with the first batch of stage 1 N/A and turbo compatible camshafts being the first ones off the line.
Exciting times ahead

RTFO!!!! That is awesome news! With the way that Mitsu dealers are voiding warranties left and right for virtually no reason... I'd like to give them a HUGE one! Any eta for a quad tb and manifold? I'd love to come in for an oil change just to watch their jaws drop. No matter what they owe my oil changes for 3 years lol!
