Your Mom Drives a Honda
Does anybody know if the throttle body from the TL would fit/work in our cars and if there would be any benefit in doing so...is it any higher performance or is it the same as ours...
There is a coolant hose that runs through the throttle body, you essentially take off your air intake to expose the TB to give you room to remove the coolant lines. He used crimpers (with the ends wrapped with rubber to prevent the crimpers from damaging the coolant hoses) to prevent the coolant from leaking out all over the place. Then he bought a tube ("5/16" fitting") that will connect the 2 lines together so that the coolant can flow without being connected to the TB. He also bought a cap to cover the now exposed coolant holes on the TB.smokin6speed said:it would be better if that DIY was a little clearer....not really following along...
I don't get it, the air going past this short length opening into the intake plenum is going very very fast through here. Anyone know exactly how fast? I'm guessing 15-25fps. One particle of air is not going to notice a dramatic (if any) deltaT as it zooms past this area and into your combustion chamber, which is already explosively hot. I think this is a pretty useless mod just like the TB spacer. I remember when these were necessary for CiTV's, where it would use the coolant to adjust the TB bypass at idle. Bypassing that made the car idle like it was always colder than it truely was (high and rich), until the engine bay fully warmed up. You got gains from burning extra fuel while the car was cold/warming. And good luck spending 60 clams on a dyno to try to prove the 1-2HP increase claimed. The margin of error between back to back runs is almost the same (even if you could dispell heatsoak), but I doubt the 2HP is worth the potential detrimental effects down the road, pulling the hoses off your TB might cause. Who knows what sensors read signals from the temperature going through there? Potential trade off doesn't seem worth it.drkangel348 said:There is a coolant hose that runs through the throttle body, you essentially take off your air intake to expose the TB to give you room to remove the coolant lines.

Doing this reduces intake and TB temperatures dramatically.
I would not do this if I lived in a area that is often freezing cold though.
The_Tofu_Shop said:kurts right, temperature is so essential inside the engines. Cooler air is more dense, which means you can burn off more of it. Thats the idea of a Cold Air Intake, or the idea why before going on the track, people ice their Intake Manifolds and their Intakes. Every little bit helps. as un-realistic as it seems.
smokin6speed said:as great as this info is and has got my mind going full speed to do another DIY mod i still am wondering if the TL or TSX throttle body would fit/benefit our car...and then once that was installed if it is possible/beneficial...then also do the coolant hose mod....
I once heard this mod is illeagle because it effects the emmission.. ??drkangel348 said:Numbers don't lie, the heat from the TB will dissipate to the intake manifold and your CAI (if installed). There are gains if you drop intake temperatures:
There are also dynos from TSX owners that prove this. This mod is not useless.
Damn dog i get like 27 mpg in my auto with no ac, and driving like grandma. HTF u get such good milage going 85?blu6speed said:This is such a worth while mod! I read this post and decided to give it a whirl. Both the inlet and the outlet can be found directly on the bottom of the TB. I went to autozone and picked up a brass connector, 2 hose clamps, and 2 hose caps- total bill was about $5. Dont get in your car and anticipate a change. The power increase occurs once the engine is hot- say on a long drive (over 20 mins). I ran about 140 miles up an interstate and could really tell the difference when I was passing. I forgot that I had the AC on! I turned that off and I could really tell at that point. I carefully monitor my engine temp constantly, and my car actually seems to be running cooler than before. Guess what that means, more mpg. Running the AC, doing 80-85 the entire way I averaged 30.8mpg according my navi. On the drive home (another 140 miles) I had the AC off. This time I averaged 34.4 mpg!! Before it would have been about 25 mpg with AC, 32 with out. I will change the mod back once winter comes back around, I dont want to have my throttle sticking due to a frozen TB. This is such an easy DIY mod, and its one I recommend to everyone.
