those flares came from jdmflares.com and are the wide zg fiberglass style.

^^ What's the story there?

And you should let me take that SF for a spin... you know, for research.

that was last friday, I went and drove around pike's peak! The photo was at the highest point about 4-5 miles from the summit but still an Incredible road!!

The car drives simply amazing, grip everywhere, and the sound of the exhaust while a bit much for the road trip, is perfectly outrageous in the mountains!!

ADaughen next time I'm out in colorado i will have to message you before hand and you can do some "research" driving

I'm a bit East of there.

If I head out that way for family I'll PM you. I want to do an H6 swap in the SF myself. I am just impressed with the whole swap.

This thing sound amazing!! I've heard it all week driving down Iowa st and then turning on university. Looks great too! Seeing and hearing your car makes me want to get rid of the 240sx and go back to subies. Lol but I yet truly never finish a build for some reason or another. So for now subie build will have to wait. Hmmm maybe a ez30r in the 240...... Hmmm, keep it up man car is awsome!

Default ITB's!!

Slowly making progress on this idea, here are a few pics of the process of taking triumph speed triple throttle bodies and running them with the subaru DBW throttle body


speed triple 44mm ITB's connected to the DBW throttle actuator


I cut the throttle plate and bore off the oem unit and machined it to fit on the end of the triumph units.


The insides of the DBW unit, the throttle plate is gear driven


The main throttle plate gear needed to be modified to connect to the triumph throttle bar…


Another shot of the modifications… I machined down the triumph d shaft cable cam to be bonded into the subaru piece.

That's some excellent engineering you're doing, but I'm curious, what benefits do you get from independent throttle plates?

Independent throtles allow each cylinder to pull in as much air as possible per cylinder and not have vortex issues resulting of having to follow through a manifold.

as for the actually hp benefits, its disputable for a street car… as for the theory, it all about the air velocity… especially with NA tunning. as with the exhaust running smaller diameter pipe allows higher air velocities. with the right combination of exhaust and intake diameters and lengths you can get a "supercharging" effect where more air is pumped into the engine… Of course this will only come at a very small rpm range so usually only really beneficial for a race motor where you want max hp….

I am after some of those benefits, but also I am interested in the overall aesthetic and performance benefits. I have always enjoyed the look of ITB's and they give a different intake noise that usually sounds quite nice. I will most likely get some larger mufflers to quite down the exhaust side so I can enjoy the sounds that come from the intake…

here is where the air supply will come from when I am finished

Debris puncturing the filter and entering the system.

Hey bud... this is the Technical sub-forum - not the General forum - so no need for the initial knee-jerk reaction thinking I'm trying to be a d-bag. We're all friends here.

To clarify, I was curious if having a filter directly exposed to the elements, specifically rain, could cause the filter to break down, or mold, etc... Maybe some of the filter even fall into the intake manifold? I've just never seen a filter directly exposed like that, so it was something I was curious about.

ah i see. my apologies. *hugs*

have a search on the internet/rs25.com for the "gravelsports" intake for the 2.5RS, it's a similiar design and has been around for ages

No apologies necessary! This place can be pretty nasty, that's why I hang out in the Technical forums pretty much exclusively. I get less hassle.

To the OP -- re: the "gravel sport" intake, see this thread on Dirty Impreza. It's pretty bad ass. Looks like they have a MAP and MAF based intake.

Thanks for the link, its more or less what I am doing









those are the current model, the black section between the intake plenum and the airbox is where the MAF sensor would go...
I am also running some basic flow simulations to see how smooth the air flows through the system.
Hoping to have a prototype manifold and air box soon so I can bolt things together and see what I get...

Where does the intake sit in relation to the scoop/undertray? How are you planning to fabricate the intake and manifold? 3D print?

I want to get the intake to sit up against the splitter, similar to how the rubber seals off against the intercooler on the STI/wrx. would like to 3d print for the prototype manifold and air box, then perhaps some nice aluminum and carbon for the final version...
