Purchased M2 med from RX7store...wrong pipe? IC?
 

here is a reference pic from Ian's car.

I believe this is the correct ASP medium with the straight end tank on the drivers side...but I thought it had the angled ends on both....can anyone who recent purchased one verify this?

However, I am almost POSITIVE that I have the WRONG inlet pipe leading out of the turbo...it is so straight compared to the reference pic that I don't think there is ANY way that will clear the airpump.

But is this the correct outlet pipe?

I just want to make sure before I contact the store...(I also seem to be missing a coupler and two clamps :mad:...yes I emptied the popcorn out and searched the box)

I don't have an m2 med (i wish i did:P), but here's a pic from Mr. Cooper's site:

The i/c-inlet pipe looks to be correct, but the i/c outlet looks a bit different.
Here's his site for all his pics:

Thanks Rotor!

I should have checked Max's site first...

The intercooler outlet pipe looks correct I think just that my pic is flipped 180...

However, I thought that Kevin Wyum redesigned the inlet pipe so it would clear the airpump better...is this the redesign then?

I don't think it's suppose to clear Air pump. I think you have to remove it in order for that pipe to fit.

Boostin,

I asked the question before I purchased to anticipate any problems...

here the opinion was that the medium did NOT require removal of the airpump

I have run the medium with both the straight pipe (picture with ruler in it) and with the curvy pipe. I had the air pump in place with both pipes. The pipes in the ruler picture were from Kevin Wyum directly. The curvy pipe (like the first in-car pic) is from M2.

The pipes you got look correct to me, but it looks like you are missing one coupler and three hose clamps. The IC outlet pipe looks exactly the same as my pic if you flip it around. I can't see the curved end of the IC inlet pipe, but it seems like it is probably the same as mine.

Max! Thanks a bunch!

It just seems like the M2 bent pipes would fit better! Never knew there were any differences.

I got my M2 med intercooler directly from M2, the pipes look like the ones in the Ian reference photo, and both of the end tanks were tapered.

Where can i get that pipe, the curved one? I have similar ic, and i didn't think that any pipe would fit in so that it will clear Air Pump and the Strut bar, But i guess I was wrong.

Also is there a chance i could see some more pics of how it clears the air pump and strut bar?

Thanks

Look for the "May 1999" picture on this page:

That's the "straight" pipe, with air pump. I added a strut bar later. The pipe would hit the strut bar as the engine moved a bit, putting a dent in the pipe. The dent was not large, but I was concerned that it was going to wear through, so I added some rubber to the underside of the strut bar. Problem solved, more or less. If you are anal and don't want any kind of interference, it might be hard to get the pipe, strut bar, and air pump all in there.

I don't know much about endtank designs...but, why is there a difference?

I have the 51R battery tray so the M2 style pipes seem to be better for me as the intercooler is moved to the drivers side slightly.

However, I remember reading a post that Kevin redesigned the inlet pipe to better clear the airpump as I stated before...this pipe seems to be the exact same...

I tried to PM him and asked his thoughts on this...but if anyone can get ahold of him please do!

Here is another pic from an older thread....

well I have the torque brace too, so my engine doesn't move as much. I just don't know how hard would it be to fabricate one or how expensive :(.

Someone was kind enough to point this thread out to me. Sorry I really don't have time to read the forums for the most part now days or I would have responded to this sooner. To address the issues here.

The IC end tanks on the medium: At some point in time after the contract with Brian he switched back to an old version of the end tanks with both tapered. This caused a problem with the airduct overhanging the edge of the tank and basically allowing air to bypass around the core instead of through it. This year when I took back production I corrected the problem by switching again to the correct version of the cores with the one end tank not being tapered. You'll see on the other versions that the duct doesn't line up correctly unless the IC itself is not in the correct position.

Tubing: Lets label them as TB (throttle body) side and Turbo side.

The TB side I'm not sure why he switched to that straight tube with the bend at the very end. I assume it was to save money on bends since the normal S bends require a lot more bent tubing. It does create problems with the beads though. The tubing gets deformed when you try to bead in the middle of a bend, meaning you warp the tube or don't use a full bead. The S bends are like that so you have a straight section at each end to form a full bead on without warping the tube.

The Turbo side tube is not meant to fit with the air pump in the stock position etc. Some people have managed to get them to fit by reversing the fittings on the top of the pump and moving the adjustment fully down and shifting the IC more to one side etc. etc. but it is not intended to fit correctly with that tube and the air pump. Brian switched to that tube with all the bends at some point as the default. I had made a number of them in the past but was only for special requests as it is annoying to make and not as desirable from a performance or appearance standpoint.

Knowing that a lot of people want to keep the airpump and wanting to make sure it's done right I've been in the process of trying to get a cast version of the tube made that will have little notches to clear things like the airpump etc. Jeff H. actually did the CAD work which turned out really well. The problem has been finding a good casting facility at a reasonable cost. We're not talking about parts that will be produced even into the thousands most likely so recouping the setup fees requires use of small casting facilities. I'll make people very aware when that step is complete. That's being worked on now.

In the meantime after some thought I will likely again offer a tube version of the pipe to clear the Air Pump until the casting thing is sorted out but there will be an additional charge for the different pipe. I'll work out the details with Jason.

So the long and short of it is, apparently people have managed to get that pipe to work with the airpump even though it is not intended to and there is more to come on an alternative, Ie: trying to get a cast part done for it.

Kevin! Thanks for the great service and response!

I used to have the M2 medium intercooler adn athe endtanks were both curved even at the drivers side. In order to make the IC pipe fit, the airpump fitting needs to be modified a little. I cut part of the edges and moved it straight to get it to clear the IC pipe and it worked fine for me when I had the IC without any trouble. BTW, when I used to have the IC, my pipe from the throttle body was completely straight.
