WRX headers vs oil filter...

[Sarra]

The WRX manifold will block access to my oil filter. Where the fudge do they put the oil filter on a stock WRX?

[AJM]

Are you going to turbo your car ,or are you just trying to get an exaust shop to do some guetto fabulous piping?

It's gonna get turboed, in the future. I'm saving up for a WRX block right now.

[Reason]

Get a oil coolers that will relocate the filter.

[StatGSR]

ummm the oil filter is in the same location, and works fine on a wrx/tleg idk what problem you think your going to have....

[Sarra]

The manifold's going to be directly under the oil filter. It'll still be accessable, but there's gonna be oil dripping on it each oil change.

Maybe I will get an oil cooler... except I don't have an automatic.

Yeah I have the STi shortblock and it seems like it's in the same place as on NA cars. The filter is not directly above the manifold, but yeah oil does drip on it if you're not careful, but it burns off pretty quickly. I actually get more oil on the manifold from my oily gloves than from the oil dripping out itself. The block is on a slight angle on the crossmember so if you loosen the oil filter slowly it drains out in a way that it does clear the manifold.

You haven't changed the oil on a Ford Duratec engine...that's EXACTLY what happens and it's perfectly fine.

It's not the case with the subaru engines however. :wink:

[Ural]

well if you guys complaining on changing oil with exhaust partially blocking the filter, try an XL7! :lol: haha those things are a bi0ch :shock:

[Sarra]

I'm giong to get an aftermarket manifold and haxxor it up. I'm going to reverse it, actually, so it exits on the driver's side instead of the passenger's side of the car. Or just get one and bend it so it clears the stock XMember and go from there.

[Perdue]

it won't block your oil filter. All the shortblocks are setup the same as far as that goes.

You are going to get a WRX/turbo legacy crossmember, right? The WRX exhaust manifold will not clear the N/A crossmember without cutting/hacking the crossmember. I still don't see why you don't just find a N/A exhaust manifold used somewhere rather than trying to make the WRX manifold work. They're a dime a dozen around here in junkyards, so there's bound to be some around you somewhere.

Because I want to turbo my car? :lol:

Ugh, they do make UP and DP's that work with N/A manifolds...google subachad or something to that extent.

[Perdue]

yeah...subachad makes uppipes and downpipes to fit the NA manifold. Also, what does turboing your motor matter at this point? You're wanting to spend extra money to have a shot hack up this manifold to either make it work with your current exhaust, or to make it come off the motor on teh driver's side, which make no sense for turboing a USDM subaru. You can't put a turbo on the driver's side because of all the brake/cluth hardware in the way.

Running pipe from the driver's side up to the "stock" turbo location on the passenger's side is not only going to add more area for heat dissipate, but it's going to cause more turbo lag than you'd have to begin with because of all the extra piping on the charged side, not to mention what you'd be doing with the flow.

If you use the WRX style manifold, UP, and DP then you're going to have trouble routing your intake through the engine bay. If you look closely, the uncharged side of the intake on a WRX runs between the block and intake manifold and come out where your power steering fluid resivior (sp?) is. This means the WRX equipment will leave you with EVEN MORE work to do, adding to the costs of your aftermarket turbo.

There are plenty of guys on RS25 using the stock NA manifold with subachad or custom uppipes and downpipes. Many of them are putting down pretty decent numbers. This leaves a lot less work to be done (IE: No crossmember swap or notch, no power steering relocation, and so on).

I'm also not sure how good the idea of putting EJ22 or EJ25 heads on an EJ20 is. I haven't researched it a lot, but I'm pretty sure the EJ20 has a vastly different bore-size, which will mess with the combustion chamber.

I suggest you start looking around on NASIOC and RS25 for more information. Do your research before you waste your money doing something that's just not logical.

[Sarra]

I heard from someone on the RS forums that failed at the 2.5 head on 2.0 block setup, so I'm just gonna save up and either get a 255 or 257 shortblock, or an EJ20R and convert it to a TD06 single turbo.

I'll be able to run a WRX Xmember and UP/DP without problem then, and without having to relocate the PS pump.

[Perdue]

Going with a swap of both drivertrain and crossmembers will save a lot of headaches and most likely be more reliable. However, it's more expensive. At the same time, it will most likely provide you with a newer motor (most swaps being brought in from Japan are 40-60k because of extra taxes imposed on vehicles with higher mileage over there), and wiring isn't a real pain if you can afford to spend a couple hundred to send both wiring harnesses out to a place like ECS so that they can do the wiring for you.

Intake issues are not too hard to address, just put a rubber hose in there and route it where you want it to go:
