Hi,

( I know this is a 2.0L and there are some limitation to what can be done for low/mid range Torque )

I am looking to _try_ to increase low/mid range torque and responsivity of my 2008 evolution GSR (and remaining somewhat legal on the warranty side so as stock as possible) and broaden the torque curve. I dont care for peak this and that. All I care is a nice broad surface under the curve

so far, I am considering the following:

- Ported stock exhaust manifold
- high-flow cat
- EBCS
- quite evidently a tune with all those parts.

is there something else in my strategy I may have missed?

thanx for your input.

Two other "standard" tricks for moving the peak of the torque curve down are: (a) increase the length of the intake runners and (b) delay the opening of the intake and exhaust valves.

I'm not sure if these are as effective with forced induction, tho'.

 

I hear the best way to make low/mid range tq is to buy a v8.

Do you have e85 in your area? BOOST will give you torque...what other mods do you have? Pretty much any mods you do will help but the most responsive/torquey down-low setup will be stock turbo, testpipe, catback, and e85. Add some kelford -b cams for epic torque spike. Ported IM/TB helps a ton too.

If you want to expand the powerband, add a bigger turbo

 

no e85 in my area

 

rally cars running from low to mid range power since they are literally dead over 6K rpm.. But you dont want to put a restrictor plate in your car , believe me.

So get a higher compression engine (you can even add 200cc to it ), and the same oem size but better spooling turbo, with a right cams and tune. The car will be quick as hell.
