I have a 2010 TSX. What kind of gains would I see from the SRI, throttle body spacer, and ported intake runners? I'm also interested in the down-pipe and the pulleys, but am too nervous the pulleys might screw something up long term.

 

There are quite a few threads now on the SRI and that vs a Cold Air Intake that will give you a lot more info. But there will be minimal performance gains from SRI or Cold Air. Both mainly for noise. Now in conjunction with other things it could add up. As far as downpipe, I may get corrected but I do not believe there is one out there for our car. Haven't heard about pulleys yet either. Throttle body spacer is out, but other than looks good have not heard to many results on it. There is a thread long thread on here about this too though. May find more info there. Good Luck!

 

you have not stated whether you are six or four cylinder.

if six, you could most likely implement most of the 3rd gen TL mods, as you share the same 3.5l engine as the type-s.

Short Ram Intakes provide the engine with cool air while moving, but at idle you'll be soaking up all the HEAT from the engine.
Heat kills performance.

I havent looked, but if the Six has the same design as far as exhaust, you then could implement Pre-cat deletes, Jpipes, and full cat backs.

Also, Weight kills performance. the 3G TL is a PIG!!!! I've lightened my car about 60lbs and let me tell you, it MOVES!

 

107whp!!!!!

 

I have the I4(MT). UR has a pulley set and the down pipe is in testing from what i have seen here on the forum.

 

Best performance mod out there is a "VTEC" sticker, "Type S" Emblems, and "Mugen" emblems. They add 500WHP at the least.

But anyway, there's a supercharger that supposedly dropping sometime this spring for the CU2

 

yeah i believe there IS a UR pulley set?

as for gain...you will probably feel a better "pull" or more responsiveness...other wise, i dont think it will be A LOT

 

Yeah there is a UR Pulley, price is kinda steep though.

There's also the P2R Intake Manifold Gasket!

And the Sprint Booster, but that doesn't really improves performance...lol
