Got my hood back from the painter for the CJ7 Project. That is a 65 Shelby GT500 hoodscoop reversed with AMC 401 emblems on them. To me it was the crowning jewl to my build on this thing. A bunch of small things left to do as well as doors. But good god this thing is fun to cruise in.

Got the intake from a fellow Type RA owner. I am not 100% sure where he got it. I know I was not able to get it through Subaru when I was ordering parts for the intercooler sprayer. Since then, ordering parts for an S209 is hard even for owners with VIN numbers.

Had my eye on upgrading the Alternaor Cover to the JDM STi Forester 2.5 Cover. I picked this up when I purchased the S209 Intake. Such a simple mod, however it looks so clean in my opinion

So I wanted to confirm that the S209 Intake bolts directly onto a normal STi/RA with no mods. So many people kept telling me that it wont work as the S209 HKS Turbo used a 3" Inlet. Well before I scheduled a protune I wanted to take some installation pictures to verify.

Removed stock intake system.





Note the smooth transitions on the S209 Intake vs Stock




Remove these pieces from the stock air box and move them over to the S209 Intake.





Install the unique S209 fender mounting bracket to stand off





Secure lower standoff to frame rail and install cover.



Install inlet



Install the intake scoop




Overall the quality is top notch and everything bolts together perfectly. OEM FTW!!! Need to get an accessport and protune before I take any drives, but this not has me thinking about future OEM+ power mods.

So far my plans are:

STi Spec C Long Runner Intake Manifold or Group N TGV Deletes.
BRZ/GT86 Throttle Body
S209 Injectors and Fuel Pump but I would love E85 and may go Cobb.

Twin Scroll or Single Scroll will determine my exhaust upgrade path.

It's doing well, still at the same 7.2 miles and professionally hard parked.

I just want to knock the loan out and then I'll feel more comfortable about balling out on the RA. I've got a few plans for the car, but honestly I'm in no rush and just like the idea of having paid off the RA and still having delivery level mileage.

My CTR is a blast though, just hit 8k miles a week or so ago and continue to love the car. It's quick and I love how it handles!

Getting back on track, is a tune absolutely required for switching to the S209 intake? I know it may sound like a half stupid question, but how much more flow over the RA intake will it provide and with that additional flow - does it really require a tune?

I continue to be impressed with the quality of your build, well done brother!!

Bro, i have absolutely no idea. The amount of people who have put this intake on a non S209 that I am aware of is...2. The other individual was on a full bolt on setup. I jist know over the years the amount of intakes that were put on Subarus with no tune always ran lean. Its just not worth it in my opinion to take the risk. And if I can get 300whp/350tq on a stage 1 pro tune or close id be happy until im really ready to go nuts on this thing

Also, if you sell your RA. Just know you have a buyer for those mirror caps haha

I understand, just figured I'd inquire and I'm fully aware that you're effectively pioneering quite a bit of these mods - hats off to you bro!


That would probably be the case, was just looking to avoid needing a tune if I didn't absolutely have to have one, was hoping it was OEM-ish enough to avoid it lol.


I have no plans to sell the RA any time soon, just want to bang out the loan before I get mod happy so I can be "financially responsible" or whatever that is.


If I ever did elect to sell the mirror caps, you would be first to know bro!

I asked COBB early on if they could provide me with the MAF scaling for the S209 or at least tell me if it was different and they wouldn't.. So I tried to get a copy of Accesstuner for the S209 and they don't make it.. you can only open their S209 maps if you're a COBB certified protuner which no requires that you also become a COBB certified dealer for selling their products..

Anyways.. the easiest thing to do would be to measure the ID of the MAF housing to see if the diameter (and thus cross-sectional area) of the intake piping is the same near the MAF sensor. If it's close, you should be okay to at least drive the car. If you have the AP already married to the car, you could monitor the fuel trims in closed loop. You can't do much in terms of WOT open loop logging without a wideband connected.

I honestly thing the car would be fine. However, it would always be in the back of my mind. I have an accessport on the way, and wanted a stage 1 protune to satisfy my itch for more power. Still deciding what tuner I am going with, but both said they are interested in doing a stage 1 dyno then a stage 1 with S209 intake dyno to compare.

Loaded my new Accessport onto the car today. I went with the 93 Stage 1 SF Intake tune. With the S209 Intake my Air Fuel Learning 1 at idle is 18 to 20. I checked everywhere for a vacuum leak, but nothing. It could me the the diameter if the MAF housing is just larger and the scaling is off. A protune will take care of that....or find a vacuum leak haha!

So far the car pulls great! No fine learn knock of any kind so far.



I also installed the JDM STi McGard lug nuts. Alot easier to install, and adds 20 STi logos to the car haha.

I temporarily uninstalled the S209 intake tonight. I have been running the Cobb Stage 1 93 Octane SF Intake tune for the past few days and have been logging some data. Car drives great with DAM at 1 and no knock to be seen.

However, on startup and idle it runs sorta rough until the ECU adds fuel. Its running super lean at idle. Air Fuel Learning 1 is at 21%. I checked and double checked for a vacuum leak, and I found nothing. So the only thing I can think of is the MAF housing diameter is large enough of a difference in the Type RA intake vs the S209 Intake. Sure enough they are quite different.

The S209 MAF housing is 3" (Poor angle of Picture, but it is 3")




Stock intake MAF is 2.75"




Tuning Subarus, and MAF scaling is something I know little about, and I am not sure if 1/4" of an inch would cause that much of a difference, but after I swapped on the stock intake my Air Fuel Learning 1 hovers right around 5% at idle now and its smooth. So I assume a protune is definitely needed.

Kind of at a crossroads now with engine mods. To keep this build as OEM as possible I am finding I would have to make alot of compromises with fueling as even S209 Injectors are at 95% duty cycle on a stage 1 tune. So they offer almost 0 room to grow at all. Group N TGV deletes would require me to drill out mounting holes on the intake which I dont like, and a Spec C Long Runner Intake Manifold swap looks very complicated for zero gain. OEM downpipe options are limited to the factory Prodrive performance piece.

So for now maybe a Stage 1 tune will tie me over until I throw caution to the wind and go turbo upgrade.....

Needed a place to mount the accessport, and decided to go with a Dialed Mounts vent mount. Overall I love the location and clean look. However, the quality was seriously lacking. Its a 3D printed piece with absolutely no finishing work. Holes to small. the nuts to secure the mount just spun as the recessed hole for them to lock into was way to small. Overall for $45 more time and care could have gone into the product IMO.





Also, my search to use only OEM performance parts continues. The downpipe was an area where I felt like there was no option. However, the Cosworth CS400 may be my answer. Technically, its a factory backed project so IMO it counts lol

I was able to source a CS400 downpipe, and it appears to be the same downpipe flange all Subarus use. Still trying to get more info. The CS400 uses a custom Garrett turbo, and not much is known about it. I may take the chance on it.

I went with the Grimmspeed catted downpipe on mine, IMO they are one of the best manufacturers of quality aftermarket Subaru parts...

Ordered the Front Facing Camera assembly a few days back, and it showed up today. Quality OEM piece as usual. Also, ordered the plug and play harness from a member who sells them on Ebay.






Also, got word that the CS400 Downpipe wont work on a standard IHI turbo. So, that leaves me with the only OEM upgraded downpipe is the HKS unit that was fitted to the JDM STi TC380. At that point, its not really an OEM piece anymore. So, the new Cobb downpipe is the way I am gunna go.

Looked into the 1 piece Spec C intake manifold, but settled on the Group N TGV Deletes. Still on the search for a Group N Turbo Inlet.

Very nice and great attention to detail.

Just a thought but maybe keep the stock DP and go with a high flow cat? Perhaps something like the CS400 cat, assuming its got to be higher flow then stock.

I think alot of the gains come from where the wastegate exits right into that blank wall having to do 2 90* turns to get out. Im content on the new Cobb Unit

Nice additions... I also went with GrimmSpeed Catted Limited ...I am a big fan of divorced Wastegate DP's... Thats pretty much all I have had.. Had the BPM on the RS.. and a JDM Spec no Cat on the STi the first time around.. I love your OEM/JDM additions..I am trying for the same theme... kinda sorta.

Not exactly.

The wastegate flap, when fully opened, is only opened about 30 degrees, which directs the wastegate exhaust in the exact direction over to the main exhaust exit where it is pulled out. Subaru engineers are not as dumb as some would like you to believe. Any major performance gains will come from the larger pipe diameter and use of a good cat like the Cobb piece(or none at all for those who can get away with it).

Actually, when you think about it, knowing that the wastegate flap only opens around 30 degrees, imagine there is a divider in place for a divorced downpipe set up. Now the wastegate gas IS actually slamming into a wall before having to change direction again to go down the pipe. Extremely overrated and may actually do more harm than good in terms of boost control.

But, it's a moot point since virtually all aftermarket downpipes are either a bellmouth or divorced pipe anymore. That being said, a bellmouth design would limit the wastegate exhaust flow less than a divorced pipe would.

With the incredible amount of detail you are putting into this car, I'd surely have a look at a Hayward and Scott downpipe. Good luck in your search.

Why Hayward and Scott??

I'd stick with the latest COBB downpipe with the GESi cat. The Hayward & Scott downpipe is more popular with the UK crowd and only uses a 100 cell cat placed closer to the turbo.

IMO, the COBB downpipe has a nicer cast bellmouth design, higher quality cat and better cat placement (from a performance standpoint). The GESi cat will also be more environmentally friendly.. but that's just my opinion

Edit:
FWIW, there will be nominal performance difference with nearly any aftermarket downpipe.
