News AMS Subaru Intake Manifold: Work in Progress

Well a while back we announced that we were going to be designing an intake manifold for the Subaru EJ20 and EJ25 engines. Many people have asked us how this is going and when it will be ready, cost etc etc etc. Well I didn't want anyone to think we were dragging our feet on this so I thought I would show you where we were in the engineering process.

Here at the shop we have a rapid prototype machine at our disposal. What this means is we can go from concept to CAD to Prototype very quickly. We can even have something rapid cast to even test the products potency. This is the same process we used for our EVO VIII intake manifold that you can see below:









Well although the below images might not represent the final product I wanted to show the members here that we are working very diligently on getting an AMS intake manifold solution to you.

Below are the images of our current ideas after they have been rapid prototyped. Again this might not even be close to what we actually come up with but at least you can get an idea of how much work we are putting into this. We won't pour the mold until we know its the best we can offer.

Euroscuby wants to put one on his Fiero. It needs that red coating for sure.

We test fit a new set of rapid prototype manifolds on my personal STI 2 weeks ago, so we are in fact working on it despite popular belief.

Unfortunately I do not have any updated release date information, but progress is coming along.

If the finished product works and looks as good as the EVO unit its going to be incredible!

Any news on a downpipe solution yet to go along with your catback exhaust??

What are you planning for the center section? How is it gonna be fed air? Stock throttle body opening? Also will this be made to work with cable driven cars as well as dbw cars?

We are planning a rotating assembly for the center section to be used for reverse manifold intercooler pipes or standard pipes.

The manifold will be available flanged for either a DBW or cable throttle bodies.

When you say rotating does that mean I could get it now and install as standard and if I wanted to later reverse the manifold I can rotate it to do so (I would assume the center section would be on vband's from looking at the picture). If so that would be cool!

V-bands would unfortunately put the manifold way over budget for the price range we're looking to release it at.

It will be adjustable to whichever direction you would like to face the throttle body. In theory you could cut a hole in the hood and run the piping out that way.

Progress is being made and LOTS Of it. We went ahead and made a sheetmetal version of what we hope the cast unit will look like...air horns and all.

We were very impressed with the numbers

Test car:

2007 STI
AMS Rotated mount V-band GT30R turbo kit
AMS Stage one shortblock
Stock heads
Stock cams
AMS FMIC
AMS Exhaust
Deatschwerks 880's
Boost: 24 psi tapering to 22 psi
Open ECU tuning
Timing untouched between passes

MAF sensor shows a 20-30 grams/sec more air flow!

Virtually ZERO loss in spool even on this small turbo at this boost level
15-20whp gains after 5000 rpm!!!!

Considering the HP level this test was done on we are VERY excited with the results and cant wait to continue testing on larger more powerful platforms.

In any even here is the before and after chart and also some eye candy

If everything goes well with the engineering process, we should have these available mid-year.

Any idea if these will end up working with a TMIC?
From the looks of the design id say its a no go.

When this is released it will not work with the top mount intercoolers unfortunately. It will only work with a FMIC set up.

Unfortunately it will not but we are going to recommend going with the Cosworth TGV delete kit with our intake manifold.
