Numbchux Posted October 19, 2006 Share Posted October 19, 2006 beataru.. taking the thermostat out of a car desnt cause it to overheat unless the radiator is partially blocked. it CAN happen, but its far from a rule.. down here in south florida, lots of us just yank em instead of replacing, because we never have to worry about a truly "cold" start. just FYI. someone had to tell me once, not too long ago. yea, I'm driving my EA82 with no t-stat in 40* weather, and it barely warms up...

beataru Posted October 20, 2006 Share Posted October 20, 2006 its also detremental to emissions... your car is designed to operate at a certain temp... so it burns properly... youll have poor power, and fuel economy because of it. But i live in arizona... anything will overheat down here if you let it!!! Quote Link to comment Share on other sites More sharing options...
m1ng Posted October 20, 2006 Share Posted October 20, 2006 Hi Guys.i want to intercool my ea82 as well.i don't see anyone mention about the small water hose(the one from top of the thermo housing) goes to the intake metal pipe?can i just cap it off?thanks.

I would keep it if I were you. Quote Link to comment Share on other sites More sharing options...
Wheelhop Posted October 23, 2006 Share Posted October 23, 2006 Do you have to add a BOV when installing an intercooler??? Quote Link to comment Share on other sites More sharing options...
beataru Posted October 23, 2006 Share Posted October 23, 2006 Do you have to add a BOV when installing an intercooler??? You MUST have a bov with a turbocharged car...... I thought that your intercooler had one on it??? mabey not... But you have to have one! Quote Link to comment Share on other sites More sharing options...
Caboobaroo Posted October 23, 2006 Share Posted October 23, 2006 you don't need a BOV/BPV with any turbocharged car, thats BS. Stock, our EA82Ts never came with a BOV because they don't run enough boost stock, to have any major life threatening effects. A BOV/BPV does one thing. When you take your foot off the gas to shift gears, after getting into it, it prevents the pressure from the turbo from slamming into the butterfly in the throttle body. It helps when running higher boost so it doesn't grenade the throttle body. On 7psi, or even 10psi, its not needed but it is a good idea, especially if you drive like a wild man and decide to crank the boost up. I have seen people make block off plates for WRX intercoolers so they don't run a BOV/BPV. Quote Link to comment Share on other sites More sharing options...

EA82DM8 Posted October 23, 2006 Author Share Posted October 23, 2006 So after much thought I think I may have figured it out let me know if I am right please. Large inlet hole at front of intercooler must be rigged up to the end of the silver thing with subaru turbo 4wd on it?? Does this need to be cut slightly or is it better just to raise it an inch or so with two new silicone joiners? Two outlets at bottom side of intercooler need to be joined to a y pipe and then joined back up just in fromt of the turbo where the old subaru 4wd turbo silver thing used to join?? Please tell me its as simple as that?......is it? Thanks Quote Link to comment Share on other sites More sharing options...
Caboobaroo Posted October 24, 2006 Share Posted October 24, 2006 Yup, the y-pipe which goes on the to inlets on the back, connect from the outlet of the turbo. The large diameter outlet on the front of the intercooler goes to the throttle body. Its very simple, just doing the plumbing isn't exactly easy per say.

Thanks Caboobaroo..........can the original throttle body be "trimmed" to ease the harshness of the bends to the intercooler outlet or are harsh bends not our enemy in an intercooler installation?

Cheers Harsh bends are not a turbo charged vehicles friend... but if you have to... and you keep them at a bare minimum then there ok... your talking like elbow harsh right??? your not making a rollercoaster out of pipe are you??

No rollercoaster piping, its just that the original "silver subaru 4wd turbo" thing reaches down quite deep towards the turbo and the intercooler obviously sits quite high, I just thought if I took an inch and a half of the end piece it would make the climb to the intercooler less steep and less angular. (if you get what I mean?) Thanks. Any easy ways to install a boost tap, or is that question for another thread? I appreciate all your help everyone.

dxrflyboy Posted October 25, 2006 Share Posted October 25, 2006 Do you have to add a BOV when installing an intercooler??? A BOV is a performance enhancer that prevents backpressure between the turbo and throttle body from slowing the turbo down, which creates excessive lag. The blowoff valve is a simple, quick, cheap, dirty alternative to a bypass valve, which recirculates the pressurized air back to the turbo inlet. I often see WRXs with the BPVs removed and replaced with BOVs. Aside from making a whoosh noise when you shift, all this does is waste the air that the turbo just pressurized by dumping it and create more lag.
