I looked at your kits, in the spare parts section of your site. Correct me if I'm wrong, but all kits come with a pair of connectors, not with two connectors of two types.

Just so we're on the same page, this is the picture that describes all of the components that you should have received.



E-mail a picture of all the components you've gotten at support@synapseengineering.com. Tell us where did you buy the kit and where are you located. We'll make sure the dealer or someone sends you the missing components. Cheers.

As you can see, I have one of the straight connectors and one of the ninety degree connectors

But this turns out to not even be the biggest probelm. As you can see, I went to test-fit this and it does not fit.

There are two problems:
1. It hits the intake manifold runner and it prevents me from bringing in the driver's side of the intercooler another 1/2"
2. If I try to fudge the position by tilting the valve more towards the driver's side, at a sharper angle, it hits the throttle position sensor.

Right now, I am looking for photos you may have posted of successful installations, to see how you did it.

Which reminds me why I recirculated the full-size Synapse towards the driver's fender.









In the photo below, I have to bring the intercooler in kinda half towards the hole on the bracket, there's another hole there.

Interesting you are having fitment issues.
In this thread: http://forums.nasioc.com/forums/show....php?t=2058269
The DV was fitted on a USDM cable TB with stock TMIC and a USDM STI with stock TMIC

Still not much wiggle room in either case, but I doubt your IC is the problem.

[Vlad]

Well, to be perfectly clear about what I have, I do have a JDM Version 9 Spec C engine, combined with a USDM Sti current generation intercooler.

The current generation intercooler is the biggest Subaru has fitted on any car.

This may still be relevant to the growing community of JDM EJ207 American Owners, as well as to the people that have chosen to upgrade their OEM intercooler to the biggest possible OEM intercooler, the 08+ Sti.

Also, David from Synapse is helping me already with my missing parts, so things are starting to look better.

With this said, I think I may be able to fix this by grinding the ribs on the OEM BPV Elbow at the bottom of the valve, I think it's wedging there and I only need 1/4" or less.

[Vlad]

I finished grinding the ribs and the valve is in....

Is There Any Sound Difference With Installing The New Dv???

The new DV valve is a bit louder than the full size Synchronic I had before. I definitely feel it responds faster.
Sometimes, at low to medium loads, it surprises me with a kind of whistle.
I like it.
I reccomend using the OEM gasket to the intercooler seating area.

i dont get anything like that sounds lower to non from the stock bypass valve

I hate bumping an old thread, but where do you run the line for Port C if you have a EWG/MBC?

[NITROS]

What version did you get? the C port should always be run. It needs to be a dedicated line off the turbo. If you have the latest version of the sb001 the C port should already be built in, no additional lines to run.

Look at the answer linked below to the question: "What is a Port C delete and what is the service procedure?"

I know they say to run it to a dedicated boost source on either the compressor nipple or charge piping. What about the lines that the MBC needs to hook up to? How would that work?

In theory that could work if it is the line pre-input of the MBC. However, I think this might not be as stable as a dedicated boost source. You could just put a T in the vac line for the fuel pressure regulator that comes off the intake on the passenger side. I would say both should be used as last resorts.

Which version do you have? If you have the old school one, where do you have the line for port c hooked up?

Thanks

Update: After several e-mails to Synapse, I supposedly have the port c line routed "correctly" as it's t'd off from the vacuum line going from the compressor to the mbc.

Sorry, I didn't check this thread in a while. I'm glad you have it figured out.

On my sb001, I have a internal c-port per their latest design. I linked the image from synapse's website below.
