Default serious, serious issues... need help ASAP with turbo placement

Where do I find a y-pipe that will work with the WRX TMIC and TD04 on my 99 RS with rex uppipe and legacy turbo crossmember? I have been told to look for a perrin one, but there aren't any available (used) right now and I don't have the time to wait for one to come up. Welding one isn't much of an option either, since I have no idea how to weld and don't have a welder.
Are there any other options, or what did you guys do for yours?


The following has been solved, thanks:
Hey guys, this is the LAST thread I'll be creating (before the project is done ), I promise. I am getting so close to having everything complete that I'm just getting restless now.
I am having some clearance issues with the turbo placement, and am thinking I may have done something wrong. I've been troubleshooting for a couple hours now and it seems like we are doing everything properly.
If anyone would like to help, I'd prefer to keep it via PM/MSN Messenger (I can do AIM if needed though).
I have pictures and can provide any info you need, just that I'd like to actually be able to talk to someone instead of doing the "post and hope" type thing after search has failed me.
My MSN is: silentchaos (at) hotmail (dot) com

Thanks,
Chad.

Yep. The hard plastic one doesn't work with my sohc intake manifold. I was told the perrin one would work, and have a chance to get a samco one as well, but am unsure if the samco silicone will work.

Noone has one =-\

How would I make my own? Just get sections of silicone tube and pieces to connect them?

hmm I would like to know as well since i have the oem wrx y pipe and tmic and I will place this on my 00 rs.

Basically the perrin one is flatter and not so huge with a one piece design (includes the elbows).

this is the one thing that has been keeping me up at night. I have everything in the mail...but i'm still trying to figure out how I'm going to mount/ connect the turbo to the IC and also how i'm going to fab an inlet pipe for the turbo....how did you fix your turbo placement issue? I have SOHC intake mani so iwould also like a solution. Can you post pics of why it isnt working?

I had to do 3-4 things to fix this.
1. Inlet pipe for the turbo -- I used the one I got in the legacy I used as the donor car. Hopefully it works good, it looks like it will.
2. However, you will NEED to either A. Do the parallel fuel delivery mod or B. swap rails to a different MY or something since the FPR on the 99's are in the way of your turbo/inlet. I did the parallel fuel delivery mod found on scoobymods.
3. Perrin Y-pipe on top of cutting 1/2" off the throttle body and 1/2" off the TMIC so everything fits properly. The reason you have to use the perrin Y as opposed to the stocker is that it is more flexible and a bit longer so that it will reach the turbo. I couldn't find a way to get the stocker to do so, so I sucked up the $150 and bought myself a perrin Y (no used ones for sale).
4. Pics to come when I get my new valve solenoid (broke the old one) and get everything together. I'll post up a DAMN good tutorial for anyone trying this, since I had many more issues than anyone else seems to have talked about in a single tutorial/faq.

*bump* for Y-pipe issues still plaguing me.

Does anyone have pictures of their setup on a SOHC car?
There's that black plugin that is in the way of my Y-pipe so that it can't hook up to my turbo.

I'm using the WRX TMIC and TD04 with WRX headers/UP with the 20mm spacer (as recommended by the rs25 AFI guys).

RS25 is king once again
It looks like I'm going to have to pull a PhilSine (the ultimate DIY guy ) and chop the stock Y-pipe a little bit and run a rad hose from the turbo to the Y.

Don't forget to use an exhaust pipe adapter to go from the hose to the inlet of the Y-pipe.

Umm....

So many parts...so long ago...

I honestly don't remember.

I had the turbo and Y-pipe in hand when I went to the parts store to sift through th eexhaust adapters and stare at the radiatior hoses.

For some reason, 1 7/8" is sticking out in my mind.

Anyways...have the Y-pipe with you when you go in.

I still need to go back in (figuratively speaking) and reconfigure my turbo-out to Y-pipe in set-up. I'm not completely happy with the angle it takes and it stresses the Y-pipe the way I have it set-up.

I will redo it before winter but after I get my new clutch put in and finally finish the fine tuning.

Its pretty much tuned but there are some points where it's hard to distinguish between a flaw in the tune or a slipping clutch.

Hmm.. Interesting. I think I'm going to try to keep the shape of the y-pipe relatively similar so I don't end up stressing it then.
Good to hear about your tune. The more I hear about my local dyno operator/tuner, the more I want to self tune
I might just end up going the same route as you -- EMU with WBO2 and road tune.

My local dyno tuner is Archer Brothers Racing. I would trust them implicitly to tune my car. The problem I face is $. I'm not broke, but I don't have enough money hanging around to pay their fees.

When the car is getting prepped for rally in a few years, I'll have more money and will have them tune it each year. In the mean time road tune FTW.
