So I've got an EA81 with power steering which I'm going to do an EJ turbo swap in (SOHC so no worries about the engine width). I have a spare non-PS cross member which I would like to modify to clear the uppipe. But apperantly there is a difference between them. Is it just where the PS lines come through or is also the fixation of the steering rack different?

And if I would have an original EA81 turbo crossmember, would that clear the EJ uppipe?

Thanks!

I'm not sure about the up pipe, but on the ps lines, its about where the lines go through and the removable plate on the bottom of the ps crossmember. On the non ps crosmember it is welded on with spot welds.

Someone knows about the up pipe part

I haven't checked to see if an EJ turbo up-pipe would fit the EA81T x-member but it certainly can't hurt matters any :rolleyes:.

The EA81T x-member is already power steering with the lines on the left so they don't interfere with the turbo.

Since we never got the EA81T in Europe it is hard(er) to get such a subframe but I seem to have found a good source in the US who's parting out a EA81T... If the EJ turbo uppipe clears the EA81T subframe then I might aswell spend the bucks to ship an original subframe instead of spending the same money modifying a non-turbo subframe.

People run into right-hand-drive/left-hand-drive fitment issues with these swaps sometimes. I think we should know what kind of EJ engine you have in mind. I'm pretty sure the twin-turbo Legacies (Liberties, in your country, I think) have a different up-pipe in a different spot.

Hey we drive on the right side (on all counts) of the road here...

I will be using a single turbo EJ engine, which always has the uppipe in the same spot, LHD or RHD...

So the question is: did someone ever do an EJ turbo swap (Legacy EJ22T or Impreza WRX EJ205) on a EA81T and did he (she? LOL) ever run into clearance issues with the uppipe of the EJ-engine...

I've been thinking:

1. if the EA81T exhaust manifold and EA82T exhaust are equally wide, and
2. if that would mean that the dent for the uppipe on EA81T and EA82T subframes is in the same spot (measured from the center), then
3. if an EJ turbo uppipe clears the EA82T subframe, an EJ turbo pipe would also clear the EA81T subframe...

Or am I making a false assumption here?

Your thinking sounds right to me.

Yeah, I know you guys drive on the same side as most of the rest of the planet:)

I will be using a single turbo EJ engine


That's the part I wanted to be sure of.

What's keeping you from running a custom one? With all this work, you may want to look into a catless 3" one to match a 3" exhaust if you're going through all the work. Unless, of course, the dent won't allow for it.

EJ up-pipe clears a EA82T crossmember (got this in my RX).
I'm pretty sure the EA81T crossmember will also work, as a member here was installing a EJ22T into a coupe at one time and had no issues.

Thanks!!! I'm going to install an engine into my EA81 wagon which has the same external dimensions as an EJ22T.

The subframe has already been organised and shipping is not too bad so I'm very happy :)

you will need to take all the heat shielding off the up pipe or get an aftermarket one, it rubs a little if you dont .
