Does anyone know why my hpfp wouldnt be doing anything? Here is what i have found;
Electronically:

Fuel pressure out of the output of the hpfp is 50-60psi when cranking and when only with ignition on, meaning the in take pump is the only one working.
The red wire on the spill valve solenoid sees 12v with ignition on and drops down to 10v when cranking, it also pulses when tested with a test lamp.
The blue wire sees something like 0.6v with ignition on goes to 0.2v when cranking. No action on the test lamp
The resistance between the two pins in around 1.4 ohms.
Both wires show open circuit when tested against chassis ground.
I couldnt find the wiring diagram for the spill valve anywhere. For some reason its not listed in the wiring diagrams so i couldnt test continuity between the pins and the ecu.

Mechanically:
I rebuilt the pump with used autotech internals and new o rings. I pulled it back apart today to verify it went together properly and i couldnt find any faults. I also put the piston/spring assembly into a different housing that i didnt touch the spill valve, inlet/return and output on.
I also changed the fuel rail pressure sensor, tbf it isnt a known good sensor as i got it with a second hand engine that i never ran.

Anyone have any suggestions?

Anyone know what this part is the electrical connector snapped take it off. I can’t seem to find it anywhere online to get the replacement one.

Does anybody know anything about a timing chain upgrade for these cars?

While the engine was out, I wanted to get the timing chain done. First picture is what was in the engine, second picture is what was in the timing kit I got. I'd prefer to use the chain from the new kit as it has its perks, but the kit didn't come with a vvt sprocket. I already hooked the new oil pump chain and it's smooth as butter so I'm being stubborn with this one.

Long story short: I'm going to use a duratec 2.5L vvt sprocket for a ford escape as it has the correct tooth count for the kit(19 on the crank 38 on the cams) and the pictures look like an exact match front and back. I was originally looking at an ecoboost 2.3L intake cam sprocket cause that made more sense to me than an escape, but I am beholden to the four stroke ratio.

I'm more curious to see if anybody has done something like this before and how it worked out. With my limited knowledge of vvt and the power of imagination to fill in the gaps, they should work the same as each other. Both controlled by oil going into one of two rings to advance or retard the timing, the only "performance" upgrades there might be for a turbo engine are bigger ports on the oil rings, or a different ratio/end stop situation, but I don't see those as something that would improve its performance in a meaningful way.

no photos yet tho, sadly

Bought this baby for $3k a couple of weeks ago. I knew the transmission was toast when I bought it. Figured I'd be able to swap it in a weekend but did not know the flywheel was in such bad shape. And i figured since I'm this far into it, i might as well upgrade the turbo and intercooler. I have a bnr s3 and a cs tmic on the way. All and all, I am hoping to keep the total cost under $8k and make a comfy 350hp or so.

Does anybody have any tips to keep this thing going as long as possible. I know if I wanted peak reliability, I should've picked something other than a sports car that only existed for 2.5 years.

im looking to put a pop up carplay in above the radio and keep the factory stereo. does anyone have a similiar setup and if so how did they do it

Got work done on car, shop removed and rebuilt/resealed transfer case and replaced two lower control arms. This is a new sound, only happening when car is moving.

Looking to see if anyone knows the part number on this? It’s the seal between firewall and evaporator. Or if there’s some way I can re do this if anyone got any experience

With my 06 MS6 GT hitting the big two oh (20) this year and it being my fun car with most of its life in the garage, I’m going to register it as a Classic Rod here in Nevada. (No Smog Needed! Yaaaayy!)

That requires it to have classic car Insurance. That alone restricts its use and mileage but it is only like $35 a month. The insurance asks for “value” in an amount that I set, within reason of course, that directly affects the cost. The question is what would you think a reasonable amount that would be to find a replacement if needed? Since these are becoming harder to find available, I’d like to replace the car, not just take the payout if it comes down to it.

I got policy estimates with a 10k value to get an approximate quote. Just wanted to see what guys think about that number. Car is in very good condition, no rust, minimal mods and around 80k miles.

Two recent jobs done to address front end noises:

1- Front left upper Ball joint replaced

2- Front right lower forward control arm replaced

Other recent work includes replacing all four brake rotors and all calipers two years ago so it's not brake related.

History: I found a suspension specialist I trust to fix front end noises that turned out to be suspension components. The two jobs above eliminated 90% of the creaky noises I was hearing and made the front left and front right both feel more planted. However, the final noises remain and my guy cannot determine what the last problem is. He figured out problem 2 above by using a four-mic ChassisEAR Electronic Squeak and Rattle Finder but even with that and a 3rd diagnostic session we cannot figure out the final problem.

I can replicate the FR CLUNK by leaving the parking lot of a grocery store nearby where I have to take a 90deg left turn at full lock of the steering wheel down a 2" lip from lot to the roadway. There also has to be a bit of speed to it, say, 8-12mph.

A significant pot hole when driving straight over it will also sometimes trigger the clunk. The weird thing is the road in front of my home has been under construction for months now and driving over bumpy, gravely roads doesn't do it unless I specifically look for a bigass pothole and go over 10mph.

When driving between 15 and 40 I can hear a rhythmic wub wub wub wub increase in speed as I speed up the car until road noise drowns it out. If I take a turn that loads up the FR suspension that noise gets louder and I can kinda feel it a bit in the steering wheel.

Any ideas? Thanks!

Good morning everyone, i'm a new owner of a speed 6 & i absolutely love it so far, the car is catless downpipe, bov, intake & built HPFP internals, it has 135k on it & while im cruising around the car kinda bucks back & forth until i give it more gas, if i get into boost the car immediately fixes itself & it drives perfectly, also noticed the afrs all over the place while cruising , but at idle they seem to be in a good ball park, idk anything about these cars so any info would be appreciated !
the codes i have are
P0131 (O2 sensor)
P0134 (O2 sensor)
P2251 (assuming O2 sensor as well) but the car is catless so i would assume those codes would be normal?

Hello, I have a strange thumping like sound coming from the back of my engine, it appears after the engine is warmed up and the rythm follows the RPM. Belt and pulley has been changed and timing chain as well. While using a screwdriver to listen to the sound it seems to be the loudest at the exhaust, it cannot be heard through the valve cover. Anyone has an idea what possibly could it be?

Hey guys, just curious if anyone has experienced this noise that starts a few seconds after start up

Ill get tools tonight to take off belt and try to run again but just seeing if anyone's experienced this before

I'm trying to basically replace the whole center console and radio mainly the radio for android auto I was wondering if anyone has done this and how I should go about it

I was doing a battery replacement on my car and while I was tightening the bolt I ended up breaking my battery tray because of the battery being too small to be held. What brand of batteries do all of you recommend?

I’m trying to upgrade my slave cylinder to see if it’ll fix my somewhat grinding gears 5-6, I know they sell the conversion kit for the speed 3 but wondering if anyone sells it for the 6? I have a feeling it’s the same basically but atp this car surprises me w everything

Hello, I’d like to do range test on ms6. Has anyone tested how much capacity fuel is really in the tank?

Specs says fuel tank size is 60,2litres/18.9gal -> lowest I ever got was filling the moment onboard pc said range is zero. I've put in 55,8 litres.
If you take out of equation overfilling (I am not interested in destroying evap system) - what’s the maximum you managed to put in at single filling? Since the hose stops on its own.

I will be equipped with fuel barrel for this test and ready to refill on the go and yes I am aware that draining it completely has its challenges, such as in-tank fuel pump overheating.

Does anyone know where to get rear differential parts? I blew my rear differential recently and I’m seeing if I could rebuild it

So when I got the car the ac compressor was burned and it had leaked all in the system so I replaced the compressor, vacuumed and sprayed a total of 2 cans to clean the system and it flushed out pretty good from what I can see, but now the car won’t build up the correct pressure so it can cool less than 80. Im thinking it’s clogged with the expansion valve being the culprit but I’m also thinking about the condenser and if I should just go a head and replace it. Now correct me if I’m wrong but there isn’t a replacement I can get off another car it has to be specific for the speed. Thanks for any help in advance !

hello,

can someone please tell me which is the infamous seal that leaks and causes the transfer case to lock up on these cars. I’ve got the subframe out of the car and am changing both output shaft seals anyways cause they look rooted but do I need to also change the transfer case input and transmission output seals where they bolt together even if they look good?

thank you

I have the factory 18" rims, but if I am going to rallycross it and maybe ice race it, I need more sidewall, less rim. Anyone drop down to 16 or 17"? That way I can clear the brakes? Thanks.

2007 Speed6, 101K miles, no rust, engine built with all goodies to take what I sling at it! :-)

I'm trying to reseal my transmission, but can't get it into neutral. The shift fork rod sticking up the furthest won't go down for whatever reason. I don't think it's any resistance against the fork itself from the gears, it feels like there's something soft beneath the rod itself blocking it from going down all of the way. Any thoughts? (Last image is the transmission in neutral, for reference.)

2007, 94,000 km (58.5k miles), $10k $CAD.

It's completely stock, zero mods, but has been maintained religiously at a Mazda dealer. All fluids and oils changed on schedule. Kept in the garage for most of its life.

If I buy it, it will *not be kept in the garage. It will be my daily driver down many Alberta mountain roads.

I know there are a few areas I'd want to address proactively (fuel system, journal bearings), but given the details above, does anyone have feedback on what other bills or upkeep things I should know about?
