Subaru Banner advice on mods

hey, i just bought a 2000 impreza L with the 2.2l in it, and i was curious about a few things:

-will intakes kits designed for the 2.5rs fit my engine?
-are there any good headers out there? (besides the ones from borla, my friend had those, but he said they crack w/o a high flow cat)
-also , which catbacks are decent?

im not trying to build a racecar, just a fun daily driver that has some extra oomf. any help would be appreciated, thanks

I do believe that the intakes will fit on your car but it might need to be moded to fit.Also make sure that you get the correct type of intake for your car as there are some for maf's and map's. There are the borla knockoffs on ebay that work just as well as the real deal and seem pretty resistant to cracking. I have them on my car and they work great, they were a little tuff to get on but a little muscle took care of that. I'm pretty sure any catback will work for you. Being na try and find one thats cheap and no larger then 2.25", brand shouldn't matter but magnaflow sounds nice.

Random catbacks high flow. Anything from TWE i think is excellent, but expensive. Their EL headers are one of the best. Creates a good amount of power too.

It's much more to your advantage, and cheaper to try and create an intake system yourself. This is what I plan to do.

Don't forget to tune!

If your car has dual port heads then yes, you can use a 2.5rs/legacy header. If you are lookin on ebay for headers, just type n "subaru headers". I just checked ebay today for a friend and there are still some na subaru headers(UEL) avalible, they are around $200 right now.

The exhaust manifold has two ports. (is that right?) Meaning the headers will connect to two points. The header will connect with 2 pipes, 4 total, then join into 1 via 4-1 collector. EL is better than UEL for power fyi.

People say you lose sound with EL, but a good resonator can fix that.

techworkseng.com has a list of dealers for their top notch EL headers.

Here is an example of a single port exhaust manifold/header: http://forums.nasioc.com/forums/show....php?t=1404179

This one is for a dual port header:
http://www.renickmotorsports.com/osc...products_id=34 <- this picture isn't that great ,but you can see on the bottom of the picture where formula91 was talking about the 2 pipes that lead into the collector.

Just take a look under your car and see which on you have.

All is not lost. Check the privite for sale forum, i club.com and 2.5rs.com for a set of use borla singel port headers if you are still interested in upgrading. Oh and the only dumb question is the one that was never asked!

Indeed, asking questions here is fine and dandy. We all love to help. We're all generally accepting as long as people are willing to learn. I still don't know very much myself.

In fact, my car is stock, I just browse here a lot and pick up a ton of junk. I am currently gathering money though.

It's a shame you can't get a TWE header...

But like v8 said, all is not lost. There are plenty of things left to do.

I'm sure you could but that seems like a lot of work for just a couple of hp. UNLESS you plan on doing cam's while your in there, then i would do it =)

borla headers alone sound stupidly metallic. you NEED to either coat them or wrap them. i live up north, so i sprayed them, wrapped them, sprayed the wrap, then put on a primitive skid plate.

don't feel bad about the single port exhaust. The early 2.2 (from 1990-1996 or so) had double port exhaust but the exhaust or our engines (I have one too) have beter flow than the ones prior to this one, remember its not always the ammount of ports but hte flow they give. Keep on with the spirit and happy driving

Taking the heads off of these motors is fairly painless. That being said, having single port isn't necessarilly bad (it's not turbo'd) and a good fun project would be to disassemble the heads and go through the intake and exhaust ports with dremel and grinding stone. Just take down the sharp edges on the inside where turbulence can be created (beneficial for any motor). You don't want to smooth down all the walls but there are definite edges where the casting came together. That will be a slight bump in power, and fuel efficiency.

I made my own intake with some of the factory stuff, a few things from Home Depot, and a K&N cone filter I ordered by dimension.

TWE will make you custom headers and since the single ports only have half the tubing of the dual ports you might be able to get them from TWE for the same as an already produced dual port. They are real cool @ TWE, if you email them templates for the flanges and locations i bet they would make you up something. Their phone # is @ www.techworkseng.com Canadians are always cool!

I took it off because I was taking my car into the dealership where I have a service deal with them and I didn't want them getting grump over it. Then I moved, and it's in my garage somewhere... where it's 19 degrees. I look around. Sorry.
