Well now that im super poor and cant have my turbo... Im on a quest for ideas to gain more whp and ofcourse as cheap as possible.. I heard from a freind with a Mazda 3, that on their forums they had a DIY/mod for bypassing the coolant lines that go into the Throttle body.. The idea behind this mod is to remove the 2 lines that go into the TB and connect them together. This will bypass the hot water from going into the TB and heating up the TB and keeping the air in the TB cooler...

My questions are: Has anybody attempted this mod yet.. Would there be any ill effects from it.. Would there really be any gains from it?

The only ill effects I could think of were people who live in frezzing climates.. there TB could possibly freeze shut do to no hot water being passed thru it.. As for gains.. on the Mazda 3 forums, they showed a dyno from a Trans am.. and it gained 6whp with this mod.. So with the size of our engine we may see 1-2 whp gain at most or none at all....Guess only somone doing this and time will tell.. So hit me up with what your thoughts are on this..

 

hey billy, i think this is done here but doesnt do much, check the tech??? idk but just that if it gets cold over there you have problems idk. I have seen it here before. good luck bro

 

nah. i dont think its in the tech i guess im halucinating again!?

 

Your right Alex.. there is a DIY for it already... https://www.scionlife.com/forums/viewtopic.php?t=55643

Mods feel free to lock..

 

you should get this...

you most likely won't see an improvement on the mpg but on the performance you will see that right away!!! you can feel it

 

I rember the thread on this.. You put it on right John? So you did feel a real improvment? Does it use the factory vaccum line? Got some pics? How much was it?

I could careless about MPG.. I want my fun car back , so I can enjoy driving..

 

Ahhh never mind John I found the thread on it.. and you are pulling my leg when it comes to feeling improvments in performance... I give up.. im gonna go buy another car.

 

AHH, BILLY! CMON! You'll get your boost back soon enough

 

Hey billy, i think you should sue hornet for giving you false hope on that ecotek thing. I just looked it up and hornet, you should sue me for telling you to go for it. haha . good times. good times.

 

So is this bypassing the TB thing really worth the effort. I hate the idea that hot coolant is heating up my incoming air. When I first saw the plastic intake I thought cool, the the TB will stay cooler and have more power. Then I find these stupid coolant lines heating it up. What a dumb thing to do to a TB.

 

Not dumb for people who actually want to drive their xB in freezing temperatures.

 

It should only flow to the TB when it's cold then. Kinda have the TB warmed only while the stat is closed. Then let it cool down to whatever temp it would be when disconnected.
Too bad a bypass couldn't be employed to redirect the coolant after the engine warms up. Maybe electric or cable operated.

 

That probably wouldn't be too hard to achieve. A couple of T fittings, a solenoid valve and a temp sensor to trigger the solenoid could work. Not that I am interested in researching it.

 

the coolant tells the idle air control valve how to operate your idle air flow correctly based on engine temp. i would imagine more headaches than hp with this mod.. wind up with a fluctating idle or high/low idle conditions

 

Yeah I kinda figured Toyota did it for some reasons... Im gonna pass on the mod..and any others on the box from now on.. Im outta the modding bizz atleast with this vehicle.

 

yeah, me too...well i will be forever pondering the blitz charger, but i had a 11 sec. caprice then put a rod through the block, sold it and got an 88 mitsu starion, dumped 4000 into that, to go 1 block, overboost and detonate number 3 cylinder, i am buying the xb to get around and look good, my quest for speed is on hold pending the lottery

 

I hear that... Evo IX or X is what I will be saving up for... Start fast and make it faster..

 

yeah, it'll be the wrx sti for me.... good luck!
