We will be testing some cams very soon

I wonder if the intake manifold can be improved..

Explain how a regrind will help the cams. Unless you plan on adding some tig to the lobes then regrinding.....

I have a feeling it can. Some shops are starting to test some prototype manifolds, but nothing big has really been released yet. There is still rumor that the stock IM plays a roll in the torque dip due to poor VE, but only time will tell.

Put shims under the cams... You grind the cam how ever much you want, then add the shims, that in turn adds the lift

[FirestormFRS]

Gotcha. So the FA20 cams are pushing up not down?

They push down. I'm pretty sure he's referring to adding shims to the valve stem top, lash adjuster, or both.

Seems it would be easier to TIG the lobes and regrind for the same results

Why would you do that? I though you guys wanted to see what was the max power you were able to make from the FA20 on stock form. No one is going to put just cams on flat 4 motor and call it a day. It just takes to much work and effort. People are going to swap pistons and rods while they are taking off the heads. Swapping cam on a boxer engine is not like swapping cam on honda motor etc. Swapping cams is not consider a bolt on on a boxer engine, is consider serious work.

And again how many miles does the engine has so far?

I agree I would rather see them work on an intake manifold and see what they can do. A intake manifold is consider a bolt on and it should take 2-3 hours to swap vs pulling the engine to install cams....

Wow, calm down. I think the cams will be done with their built engine, not the one that is currently being used. They are still working on pushing the limits of the stock engine before they drop in the built one. I have seen the car in person quite a few times. While I don't know the exact miles on it, most of the miles have been put on during its 180+ dyno pulls. I know they have beat on it in the streets a bit, but we are also not finished with winter yet. Also, the car is usually torn apart quite a bit between all the R&D going on with their turbo kits. So I don't believe it is being daily driven at this point.

We are in the process of doing a intake manifold for a S2000, so we are aware of what is involved with the whole process. Making a intake manifold is not as easy as it sounds. A sheet metal Intake manifold would be painful to produce in mass quantity. Therefor, it would need to be done by casting, and casting a manifold takes a lot of time and money.

The bottom end on these motor are pretty solid so far. Subaru made it really easy to work on these cars. Although the goal with our car is to push it to the limits and see how far we can go. The main goal that we are trying to achieve is a stock motor that can carry power to atleast 9k.

So, you why do you want anything more than 604 whp 400+ wtq??

I think at this point, its good that they are starting to explore upgraded components. I don't know what else more you expect out of the stock engine. Yes, it may make more power... but after 600+, you can expect the engine not to last very much.... Might as well start testing for upgrades.

I appreciate the well-roundedness FBM brings to the table. Gives up the ability to make stupid power, and be reliable while doing it

We want to rip it apart to see if the are any signs of wear and tear, but I think we will just run it till it gives up.

We have a engine on the stand ready to go and we will be testing our cnc ported head with cams in a month.

The heads will be flowed before and after,then tested in the car.
