I have one which is identical. It does not delete the TGV, it sits on top of them. If you notice there are no injectors bosses on the runners.

The runners are too small and where they enter the plenum they are just cut of straight. There has been no attempt to improve flow with bellmouths or even blending them into the wall of the plenum.

I had this when I made the decision to have my stock manifold because I thought I could get better flow out of it.

Here's the pictures of mine

To be honest, if you're really running a twinscroll 8364 setup (please tell me you went external wastegate), I would just drop the $1200 on the Cosworth manifold. I really hope you've taken care of everything else, though (oil system, fuel system, exhaust, valvetrain, engine block, fuel/spark management, boost management, drivetrain, drivetrain, brakes, etc.). Remember, you get what you pay for; paying less for sub-quality parts leads to paying for a metric a**ton of repairs later. For example, if you bought that manifold, under full racing conditions I could fairly easily see that little "air divider" shearing off and suddenly becoming one with your intake tract.
I'm with these guys, my boss has one on the shelf in the shop. It's garbage.

kimokalihi - It looks like it's out of the newer Impreza's; 08+ I believe. Mind you, it's made for N/A EJ253 engines, not a turbo motor. I can't say anything for the flow numbers, or how much boost it can hold, but I seem to recall the runner length/diameter is, well... it certainly isn't ideal. I suspect that depending on what boost level you plan to run, it could help in some areas, but hurt in others.

A little off topic: Nice that you're running an EJ20G... what did you do with your EJ22? If you still have it, I might have a happy home for it . Also, are you a member of SL-i.net? If not, you should be!

Thanks for the info. I blew the ej20g after 3K miles. I have a thread in the built motor section about what my options are to replace it. Engine was knocking and blew the piston rings in cylinder number 2. The EJ22T was not included in the sale of the car when I bought it. Sorry.

Should I be a member of SLI? I think I am but I don't post on there because it's all newer gen legacy guys so I spend 90% of my time on legacycentral.

Ah, that's too bad (about both engines). Last I was there (used to have a '95 BK chassis wagon) it was mostly older Legacy's, but I suppose it could have changed since then. Mostly second and third gen, but there's definitely first gen-ers on there. I must admit I never really spent much time over at LegacyCentral, so I don't know it very well. My opinion is that at least you're a member of a Legacy-specific forum.

I would suggest replying via PM on this one: What's the shape of the EJ20G in as far as the cylinder walls are concerned?

Whats wrong with the internal WG TS (assuming youre refering to the EFR8374) ?

I did go with ewg BW EFR 8374. As for the intake manifold, I just thought it was another option for an intake manifold. I would have gotten the Cosworth if it was a design that deleted the tgvs. I am actually using a 2.5i manifold modified by Outfront motorsports. I had Jeremy weld bosses for Hydramist meth injectors on each runner:

Don't worry, it's taken care of.

Excellent, guess I'll have to check out your build thread. Are you using standalone engine management, by the way (judging by the fitting you've added to the middle of the manifold, I'm guessing you are)? If so, you could have just removed the TGV butterfly and motor, and plugged the holes for the throttle plate rod. Additionally, APS makes a set of replacement TGV deletes that also have provisions are additional fuel injectors, which could be quite useful for your application (depending on your injector size/whether or not you care about street drivability of course).

R1Z4T - There's nothing inherently "wrong" with internal wastegate (and in fact the EFR turbo's have one of the best internal wastegates I've seen, at least for twinscroll setups), but if you're trying to decrease spool time, having an external wastegate (or in the case of a twinscroll setup, two of them) is ideal. There is, of course, a disadvantage in packaging due to engine bay space, but every setup has its advantages and disadvantages. Similar concept for running an external BOV (in the case of the EFR turbos). Basically, if the engine bay space allows, it's generally better to go external. Besides, who doesn't want a couple of Turbosmart Comp-Gate40's and a Synapse Engineering DV sitting under their hood? I certainly do .

I'm curious how they handled air distribution with it...I can see that on the backside that it's a bit deeper(or taller pending how you look at it).

Definitely not a manifold that I'd run a single point meth injection on!!

it's for making big power...that shouldn't be the first question asked

how much is the VE curve tilted upward and how much is the powerband shifted to the right?

everyone has just made their own.

I know Vern (vmiz) had talked about it briefly for All Aspects twin turbo WRX...or maybe it was Duncan's (dunk) track car.

I just orderd the same intake from outfront with fuel rails john over there seemed super cool I will post pictures once fitted
I was in the process of building my own intake manifold but after seeing the flow data on this intake my turbo cannot out flow it
It flows 80cfm more air at 29 psi over a stock sti intake
And the runners are within 4cfm at 29 psi
The red sti intake has a 10 cfm variance

I had no idea how much work shaving the manifold was going to be when I started

that said, after some grinding it looks like there's room for a turbo inlet. I'm psyched.
