Default 2.5t update

I spent most of this weekend in Southern California putting the turbo kit I bought from Ian in at my friends house. This ASR Stage II kit went in fairly easily. All I had to do was add about 3/4" to the up-pipe to make it work w/ my auto tranny. The oil feed and return line on the other hand were a b$&*h! So I have 2 questions

1. Does anyone know where I can get pre-made oil feed and return lines for the ASR kit?

2. How much is a 3" cat? My car sounds LOUD because the down-pipe replaced my cat hehehe, sounds like a race car. I like it, but Mr Policeman wont at all. I also need a 3" Cat-back system. If you guys could help me out that'd be great

Look to Random technologies for your cat
As for the ASR trubo oil lines....find someone on the board that has one, see if they will measure it for you. other wise, figure out how long of a feed and return line your gonna need, and get them made. How do you plan to return your oil line to the pan?

I would rather pay about $150 for a 3" random tech cat than get a $50 from Summit. No offence, but I like quality and the $50 is questionable.

For the oil feed and return line try www.autocaresubaru.com. I would suggest not using their return line though and instead tapping your oil pan and running a steel braided line down like most everyone else does.

I have the autocare subaru oil feed line that taps in under the throttle body and am quite impressed. It's complete and only about $40, well worth it.

Thanks for your help guys, I actually already have the feed/return lines in, but the feed leaks at the block.

It's really only $150 for a good Cat? Amazing.

Tom at Ludespeed sold me a oil pan w/ the return already welded in so my return is taken care of.

If ISR has the feed line then that would kick a$$. I will call them RE: it fitting the t3/t4 hybrid Turbonetics turbo directly. I spent WAY too many hours Saturday and Sunday at parts shops, I don't want any more hose fittings to deal with!

You'll need a 45 degree elbow to hook the oil return line up to the turbo. Makes clearing of the steering crossmember that much easier.

Part no CTO-6007.

I have one of these in 2.5" in on my car, and I very rarely get a CEL.

Hey thanks mate, I actually already hooked one on there, and you're right, it did work much better :-)

Do you guys think that I should run 3" or 2.5" piping from the cat-back? (Will have turbo running about 10lbs boost)

Question How about Catco Converters?

http://www.discountconverter.com/dealer.htm

They look like they have a good selection. I'm thinking about buying a cat converter from them for my XT6.

Default new options

what do you guys think?

www.summitracing.com
CTO-6007 Universal, 14 in. long, 3 in. diameter slip fit inlet and outlet, stainless steel, catalytic converter ... $50.99

BOR-40944 3 in. inlet/outlet, 16 in. x 4 1/2 in. x 7 7/8 in. case size ... $129.95

then I could get some-one to cut off my current down-pipe at a reasonable length, install the cat, then go 3" piping to a flange, bolt on another piece of 3" pipe to the exhaust.

aussiebrydon:

I'd go 3" with that much boost, otherwise you are likely to see too much backpressure. You haven't said what you are doing for engine management. I'd be afraid to run that much boost with piggybacks.

thats my boy Ian gots my back right there Ian should know what I have, he sold it to me. Ian, the install went great, but the feed-line we got just didn't want to work, it leaked slowly out of the fitting on the head. oh well, I suppose I'll haveto bite the bullet and get the real deal from ASR. Hopefully next week when I fly back down tto Southern Cal I'll be able to get it all together right.

thanks mate #:-) I hope my Impreza will be a fast, reliable machine after this. I'm going to get feed and return lines fabricated at ISR, and then insert a 2.5" cat into my new down-pipe, and go 3" pipe to a Borla XR-1 muffler. I might just try and install the TECII this weekend, <sigh> I have a feeling it's not just a weekend job though, we'll see.

Is your new downpipe 3"?
or 2.5?
if its less than 3 than dont bother going 3" from the center back. It wont help much and will only increase costs.
UNLESS you know you will be running, or are running a 3" DP, then its worth it.

yeah dude, new down-pipe that came w/ turbo kit is 2.5"

really? I shouldn't even bother going 3" from the cat-back? Doesn't make that much difference? I actually just checked the SummitRacing website and the 2.5 and 3" mufflers (Borla XR-1) are the same price. Do you know if 3" piping from the local muffler shop (people who will be putting it together) will be significantly more expensive than 2.5" piping? I thought the difference would be negligable

- thanks for the input

Two of us installed a TEC-II on my car in about 12 hours (maybe a little more, we were groggy towards the end). Using a lift would've made things a _lot_ easier. You should have no trouble getting it installed over the weekend. Now, tuning it, on the other hand...

Another problem with 3" is flanges - you can't find a 3in 2 bolt flange. You'll have 3 bolt flanges. So you'll have to put a new flange on the 2.5 in downpipe.

Oh thanks dude, that's awefully nice of you. I'm actualy going to get them made, my buddy Eric (work was being done at his place in Corona, CA) is taking care of it. He bought a tapped oil plug (the one on the top-side of the engine right by the MAP sensor) from ISR ($10) with the tap the same size as the feed plug on the turbo. Then he's going to get steel-braided line made at Bonico I think, that's exactly the right size, same for the return. I think that'll work, what do you guys think?

For the exhaust, I already ordered a 2.5" cat to go in my 2.5" downpipe, then a 3" Borla XR-1 12 long oval exhaust. I don't think there'll be any problems w/ 2/3 bolts on the flanges, cause Eric's local exhaust shop is doing the work, fabricating from 3" pipe, and cutting a section out of the 2.5" down-pipe for the cat.

LoL

I have ASR Stage 2 and mine also leaked on the engen, so I went to a subaru diealership and bought some kind of teflone paste (I'm not sure exectly wich one) and then took appart the connector and placed that paste all over the thing. put it back together - perfect. hasn't seen a drop of oil for few month now.

Just an idea.
