I did try to search for my answer & I didn't come up with what I needed. I apologize if this has been already discussed.

Just curious to see if adding this TB to my 4B12 if it will actually add HP/TQ or what? Has anyone had there car on a dyno before/after with this mod??

This would be going on a Lancer with the CVT trans.


Thanks everyone.

im curious as well. i also have a gts but mines a manual. if it helps i think that would be a great idea

so i'll answer the question for you since no one will. i got a 2008 eclipse gs 2.4L TB 4g69. installed it today and did the coolant bypass and when i first started it i had a weird idle issue so i shut it off. I turned the car back on and it worked like a charm. did a test drive with the old aftermarket intake ( so it was much smaller ) and i noticed a big difference and throttle response was amazing. Im going turboed in 2 days so this is going to be a big addition to my ride.

A lot of people have been trying to do this but it's really minimal gain unless you're going big like turbo or crazy n/a. Usually it'll yield at most another 1/2hp maybe 3 with a tune.
