For the purposes of the test it won’t matter too much. Without a spill valve, the car won’t run at a pressure high enough that whatever sensor is there will have any issue reading.

Your discretion, but I’d say test it at your earliest convenience. Fuel relief problems commonly get confused with fuel sensor.

What does the accessport actually read for your fuel pressure? Sometimes you can get a 192 for having a bad fuel pressure relief. A datalog of you trying to start the car would be beneficial here. Here’s a way you can test it. Disconnect your spill valve electrical connection and turn the...

I'd give CS a call about CorkSport specific questions. The guys over there are very happy to help, I've called them quite a few times myself. One of the things I love about CS. +1 (360) 260 2675 Business hours are 9am-12 and 1-5pm, Monday through Thursday (they're closed Friday through Sunday)

TS-1 was received today. Took some photos of it with and without the peel. Clocking was pretty simple, 6 13mm bolts for the compressor side, 5 13mm bolts on the turbine side. Not sure the length because I didn't think the measure them, but I could get the length if someone wants. Compressor...

Originally I wasn't going to make a thread like this, I don't think there's all too much that makes my build special, but @Enki convinced me. This isn't a full build diary, most of my build is pretty much done, but I'm going be highlighting me going big turbo. First and foremost, some context...

look mom i won

Update on the FoST high pressure fuel sensor experiment: After a having the Ford sensor on for a bit, I started to notice a very loud screeching on cold starts. After some troubleshooting and testing, here's the conclusion: the Ford sensor will see slightly less than actual fuel pressure (I...

I hate to agree with this statement, but honestly it has a lot of truth to it. Mazdaspeed is an aged platform. Not to say you can't daily them, but don't be surprised if you get some days where you have to uber to work if your speed is your primary mode of transportation. Most fixes won't be...

I use the CorkSport one. It was designed by CorkSport but uses Cometic's aluminum foamette (AFM) (and as such is reusable). Team effort for what I think is a phenomenal product. I use it with my Focus ST intake manifold on my speed.

Based purely off of what you've said, a throttle body sounds likely. Sometimes DTCs are sent erroneously because of other problems (e.g. crank position/cam position codes can be sent if the engine is just running like absolute shit, I've seen it happen with a bad pressure relief valve). Upload...

That would be a part of your variable valve timing actuator. VVT sprocket is cooked. Needs replacing. There should be a spring swimming around in the oil pan too.

Yeah, to that all I can say is good luck. It’s already a swapped car, and L3-VDTs don’t have a whole lot of emissions controls in the first place. Again, it’s possible to hook up the EGR, just not something I did nor was it intended on the ST intake, so you’ll be treading new water there.

Yes? I'm not certain what you mean when you ask if it'll change the emissions much, but I'm assuming you mean actual g/mi or g/km output. EGR burns up unburnt fuel from the exhaust, so it'll increase carbon output by removing the EGR. Maybe not by a whole lot, but it'll still have a measurable...

No, the mazdaspeed only has VTCS, no VICS. VTCS, from a performance standpoint, is a hindrance, as it doesn't allow the air to fill the volume that's available directly before entering the head, whereas VICS being much lower in the plenum allows for the volume to equalize before the air enters...

Yeah, no concern about flaps at all with the Focus ST intake manifold. Yes to the second. Not just in WOT, but even in boost too (which may not necessarily be WOT). I feel that. There will be some cold start differences, it'll rev a little higher, and you'll also notice that when you're in...

As far as desired vs actual pressure, it seems to match up exactly to what my ECU sets as the desired pressure, all the way up to just barely under 1900 (at which point the PRV has already cracked open anyways and is actively bleeding pressure). I couldn't find any hard numbers for rating like...

Apologies, updating again. I went ahead and bought the Ford sensor to test out my previous theory. It ended up working and reading fuel pressure just the same as the Bosch sensor (I normally run the correct P/N as previously). The Ford sensors (to include equivalents like Dorman 926-432) are...
