bad news. wrx oem bypass valve does not fit.

i wanted to use this just for the reason that i dont want a loud sound and i want it to recirculate. maybe i can make it so an after market bov just vents back in. yes that is waht i will do. gosh i love thinking outloud while on this board. anyone think of any harm that might come from this?

the reason it doesn not fit is because it hits the cables on the side of the throttle body.

all that work of taking my car apart for nothing, nothing i tell you. ugg.

or, i can get the turbo legacy bov to be mounted onto a wrx bov adaport plate so it will bolt onto the ic. ah, great idea again.

why only 96 or earlier?I'm talking about 02' + wrx's.if I change the turbo to a wrx td04 and then use the wrx intercooler then I would have the right angle right?I know you need the early 93-96 tmic if you dont change the stock legacy turbo to have the same angle.the new wrx i/c's are going for less then the 93-96 i/c's as far as I can tell and are easier to get over here.not sure but they flow better too don't they?

Ive tried that and it doesnt work. The wrx compressor outlet shoots directly toward the throttle body. It only clears it by millimeters. But...maybe the uppipe is bent differently on a wrx...hmmm..something to look into.

I'm sorry but exactly what did you try?did you get a '02+ usdm TD04 turbo and '02+ usdm wrx tmic then try to put them on the legacy turbo?If not that is what I'm talking about,if yes then thank you for hey wait I think I just relized what you mean. our uppipe mounts the TD04 to close to the throttle body?please clerify this may really alter my plans.

WHY cant there be any easy installs on our cars??? So subie kids tells me the wrx bov does'nt fit then i find out the intercooler bumps into a coolant line coming out of the coolant tank. any tips on how to move the coolant tank???

subiekid: the y-pipe should come with the intercooler, the hose you must fabricate can connect to the stock wrx y-pipe.... however, i was not able to do this cause i needed my car on the road (rushed job):

Rather i used only one of the two inlets for the wrx intercooler and did NOT use the plastic y-pipe. I took the drivers side intercooler inlet and capped it off with a metal plate and gasket. Then i took the metal "thermostat housing looking thingy" from that side and mounted that on the passenger side intercooler inlet. Theoretically the flow will not be as good, but after inspecting the size of the compressor outlet on our stock turbo i found that it is the same diameter as using one inlet on the i/c. Doing this allows the "turbo - i/c" hose to avoid all the crap around our throttle body (ie: hard plastic emissions lines & pitch mount), and avoids having any kinks in the hosing.

In order to use the wrx y-pipe, you will have to shave the castings down a bit. The set-up of the y-pipe and it's 2 metal elbows do not straddle the ptich mounts bracket on the firewall as i would have hoped. This prevents the intercooler from sitting low enough in the engine bay to allow the hood to be closed properly.

*I hope the pics i have up currently give an idea of what i did.

later:)

wow, i was trying to make a y pipe so that i could use both inlets on the ic. hmm, that is interesting. i was wondering why the elbow that should be on the drivers side is on the pasenger side. i now know that its the only one you use. i get it completely. it all falls together now. well i am gona go a different road. my road is going to be filled with pot holes and maybe even some closed road signs. what i am going to do is make it so that the y pipe uses both inlets, and the y pipe will also have the legacy turbo bov on it. work will start today. i will get going to the parts store and getting a bum load of pipes. the reason why i want the 2 inlets is because i plan on doing some heavy boosting and want my motor to have as much air as it can get. thanks for the help.

coolent tank issue for me is not an issue. the tank was busted when my 92 turbo got hit. i am running no coolant tank as of now. i soon hope to get an aluminum tank and will mount it by the brake booster.

guy at napa said that part number if for a carb kit or a muffler. and he would not let me go in the back and look at the hoses, what an ass. i just wnat to beat old people till they are all bloody. they all think that just because i am a kid that i am some kind of thug and just wnat to cause trouble.

I'm sorry but exactly what did you try?did you get a '02+ usdm TD04 turbo and '02+ usdm wrx tmic then try to put them on the legacy turbo?If not that is what I'm talking about,if yes then thank you for hey wait I think I just relized what you mean. our uppipe mounts the TD04 to close to the throttle body?please clerify this may really alter my plans.

Yes, that is what I tried. After thinking about it I realized the uppipes arent shaped differently, its the intake manifold. The WRX isnt as deep as the older ones. Thats what keeps it from fitting.

damn,That sucks.So an aftermarket wrx uppipe wont solve the problem?You know I remember seeing that someone here put on a TD04.I wonder what they did.Maybe we could just extend our stock uppipe or do a custome uppipe to solve problem.

i am going to go for air to water direct bolt on now. front mount is not what i want. i will still work out a pipe system and sell it on here. maybe i can get something that i like.

ok ok

so the reason that the gda intercooler won't fit is due to the diffent intake manafold the thottle plate on a gda is about 2" closer to the front of the car the turbo geomerty is the same, just without the upturned inlet..

where i have some confusion
the stock LT turbo compresser housing angles up at about 15 deg
if you clocked it straight, which you would need to do to get either the air to water or air to air intercooelr to fit, will it hit the idle air bypass valve?
the ej20gs which the intercoolers came from have the idle air valve on the runner for cylander #3

Well despite the fact that, my intercooler bumps into a few things, the wrx bov doesn't fit, my pipe conector things are backordered and it sounds complicated for air to go into both holes, im still going to make it work, some how some way, its just gonna take longer than I thought.

from what i was told the air to water did not need to ahve the turbo clocked to install that ic. can anyone tell us for sure?

I HAVE THE BEST IDEA IN THE WORLD

take this y pipe and just rotate the joint that goes onto the turbo.

or try one of these, i will order one and tell you guys how it goes.

http://www.g-force-motorsport.co.uk/aps/ccd.htm

then i wil get a bov adaptor and run the legacy turbo bov.

a hole will have to be made to ven the gas back into the intake.

Thats actually the second best idea

For the stock system couldnt we take a hack saw to the piping, get the same diameter elbow from home depot and use those short lengths of hose to connect the whole thing?

i thought about that, but the stock pipe is soft, and if you put a rubber elbow on it then i feel that it will just bend and not hold up. i think it would be a good idea to try. i am going out of town this week so i will not be able to try, so you try and get back to me. or i can run over to home depot tomorrow night.

if that y-pipe ends in the same position as the stock wrx y-pipe (which it should) you may have problems running into the hard plastic emmisions lines on the side of the throttle body. Aside from that rotating that elbow should make the connection much easier and allow better flow without kinks in the line.

Keep us informed:)

the guy that i talked to said the perrin ic pipe kit is very flexable. he said he thinks it will be able to bend like i need it to. he also said if it does not work then he will take it back and sell me the aps unit. he said the 1 section pipes are very hard to get onto the car and take lots of work.

I tried to fit both of my intercoolers today(Saab 900/ WRX IC) I actually got the WRX intercooler to fit in the engine bay. I haven't closed the hood yet. I didn't even get rid of the A/C. I'm gonna see if I can have one of the intercooler ports(Near the A/C side) covered up and blocked and use just the drivers side port to go to the Turbo using some Samco superflex hose. what do you think?

I'm gonna try and use the Stock BOV but rotate the bypass up so it will clear the throttle body(hopefully clear the hood as well).

While trying to fit the Saab IC I broke off one of the coolant hose ports on the overflow tank. That part is plastic and $125 from the dealer. I'm gonna try an retrofit a WRX overflow tank($100) since it is metal and cheaper.

I'll let you know how it goes

Could I see some more pics of the coolant tank transplant? I'd like to see what shape of brackets I'd have to fab up when I do this.

Thanks,
Mark

Turning the BOV return thingy around still won't clear the throttle cable stuff. I fit the WRX IC in without that little attachment thingyon the BOV, and there was like a millimeter of clearance, and if you want to turn the thingy around, there is a little notch you have to shave down. But , try it anyway, if anyone figures out how to fit the stock BOV of a WRX, please inform me. Oh yeah, and more on the coolant tank moving would be helpfull.

Were you able to fit the entire WRX IC in there w/ both IC outlet pipes. I'm gonna try and fit mine w/ only one IC outlet(Drivers side) and see if I can have an exhaust shop make a piece to cover up the other outlet.

I looked at my WRX coolant tank. I don't know how its gonna fit but it has all the correct lines and is even cheaper than an OEM legacy turbo replacement.

I'll let you know

I fit the entire IC in with both ducts on the back, it fits, im still waiting for Perrin to get me my IC hoses. Im pretty sure it will fit with both inlets. The next thing to figue out is how to get it connected to the turbo. I think i might be able to cut the existing plastic piece and connect it there, Might just have to get more hoses im gonna photo document the whole install.

Oh yeah, any recomendations on where to move that grounding thing next to the firewall above the engine mount??

Did you keep your AC? I'm gonna try the hose I got today w/ one of the IC ports blocked off. Would you mind taking a picture of you IC installed and emailing me a picture?

I would like to see how the Perrin hoses fit? I just think the passenger IC port will hit my AC line.

I found out we can run the OEM BOV w/o the bypass. That way it will be atmospheric. Just have to plug off the hole in the inlet duct. I'll take pics of the WRX coolant tank when I get it this week. Still have to figure out how to mount it.

I got rid of my AC, but i think you could rotate the stupid bend the other way around somehow. Once I get everything in order I'll post lots of pics. Only drawback to having an atmospheric BOV is the rough idleand running rich from what ive heard, but if there's a will there's a way right??

get a turbo xs bov flang and just use the legacy bov
