This might be a dumb question, so i am ready for a "make fun of that guy" quote. Instead of buying a hose coupler and connecting the two ends off the TB, buying a longer hose and connecting the ends directly to the outlets ( i am not sure where or what the ends of the hoses that connect to the TB go... so where ever that is, i am calling them the outlets) Would doing this make any difference vs the Coupler, i.e. better flow?

you do not use a hose coupler. You ditch one of the hoses and connect the other end of the remaining hose to the empty hose nipple. then cap off the nipples on the TB and you're done.

Sorry to dig this back up from the dead. It was the only one I could find on the topic. I have a question about this "mod". I'm thinking of doing it, but my buddy (a GM mechanic... er sorry, technician) says although it would be a good thing to do in the summer, it'll cause rough idling, stumbling, and general poor performance in the winter. Any truth to this? I'm in western PA and it does get pretty cold (down to -10 or -15 some nights).

Personally, I'd do this mod during the summer, but reconnect everything back in the winter.

Although it is very easy to perform, I don't think it's worth it. Yes, you do get some minor rough idle and stumbling and no, it doesn't really give you any worthwhile benefit, IMHO.

Is this still applicable to the 08. I haven't had a chance to see my TB yet.

soooo im bumping this thread.....

someone needs to post the exact size of the hoses 4 pages and not one person mentioned the size.

Im about getting ready to finally start my swap and need to address the issue that I dont have any of the stock hoses for the throttle body and im not exactly sure what size they are...are they 3/8"?

3/8, that's what caps off the TB anyway, so its the size of the hose.

sorry to bump an old ass thread, but was doing TGV's, parallel fuel lines, air pump delete etc etc. pulling the manifold was a PITA!!! partly because i missed a few things LIKE the coolant lines and was by myself. because i did this mod on my 99 SI i figured to go ahead and do it because putting everything back on stock would be an even bigger PITA. i jumped on here just to make sure this mod was ok to do on a Subi with drive by wire. now that im sure it is ill go ahead and add something for this guy.

yes this mod is applicable for the 08+ wrx. but its going to be hell to do since the hoses and clamps are under the manifold with no room to get to.

on a personal note, i know every other subi uses metal intake manifolds. so doing this mod to our plastic manifolds should see some nice positives. i know by touch i can touch the plastic and while its hot, there is no way its as hot as the metal ones. so by doing this on our cars it should keep the IC temps even lower than on the other models.

Holy old Thread Batman..

The cooling system already has an expansion tank that is nearly as high as the intercooler, why would you need to go higher?

The TB coolant lines do not allow anything entry into the intake system unless the gasket is blown, then it would let coolant in. Hooking meth to it would be useless, it would go in one side and out the other.

Thought meth had to be installed 6-8in from the TB and not facing any bends, so it has enough time to expand or atomize; if I'm using that right. Blasting liquid meth at the front (or back if your reversed) of the manifold is just going to send meth everywhere and might even get blow back to the TB. I don't think it would distribute evenly.

d000000000000000d......if you cant see the implications of the idea and visualize the possibilities....

and using nozzles at 150psi wouldnt leave much doubt about atomization

maybe you just dont unnastan what I had in mind

I bought a 75 degree 1.50'' a 90 degree and this.

http://www.jegs.com/i/Be+Cool+Radiat...72099/10002/-1

for my intercooler setup I have a radiator that has the cap too low, below the

headlight.

i didnt read the thread but i take it this is about removing the coolant that flows through the TB? i just took the one hose that comes into the throttle body and looped it over to the fitting on the block were the return line goes. takes a minute to do with the tmic off. a thought of mine has been to use this coolant though as the lines that feed liquid cooled ewg's from tial. basically its going to be doing the same thing but keeping them cool instead of heating the TB up like it usually does.

the TB bypass really doesn't have any proven gains, and will potentially cost you mileage. Not really worth doing.
