engine

So I'm in the middle of building my Speed engine right now. The block hasn't been machined yet, but when I eventually get it machined, I want to get 88mm Manley rods and pistons for it. One of my questions is, should I wait to get the rods/pistons until after machining the block, or get them...

Hello all, I’m running into a huge problem on my speed 3. I’m having a cylinder 1 and 4 constant misfire. It will randomly stop and run fine then go back to misfiring. Recently it has not stopped misfiring. What I have done: Spark plugs replaced and gapped MAF replaced Set of fresh injectors...

I have a 07 CX7. I have taken the engine out and rebuilt it. New pistons rings, new VVT sprocket, new head gasket, new crank shaft position sensor. Time the engine, the valves were straight so cleaned them up. Did a compression test and I am getting 30 to 33 psi on 3 cylinders and 1 cylinder is...

Hey guys! Hope yall are doing well :) I have been rebuilding my motor for about 5 months now XD taking a wile as I am also trying to get a degree :/ But I had a few questions regarding re-installing the closed block and transmission into the bay. I just re-attached my catback and wanted to...

Good Day All, Pretty sure this is my first post here. I have had a 2013 Speed3 since about 2017. it is the Daily Driver with a few upgrades. My concern right now is the balance assembly. I have it out and all the shims are on their feet so that is good. and I plan to put it back, because DD not...

Hey guys, so I'm scratching my head on this 1. So I started noticing some similar issues to when my last map went bad; high koeo voltage, overboost conditions, high idle with clutch engaged(foot off). So I started shopping, bought a Bosch 3bar but ended up buying the gm version instead. Part...

Hello All, Not sure if this is the right place for this post but I thought some of you would be interested to see the failure of my recently aquired 2007 MS3. I bought this car knowing it had low compression in cylinder 3 and after a 1 hour drive home I parked it in the garage and started...

It rained a couple days ago and I forgot to wrap my intercooler when I went driving. I got home and started it a couple hours later, white smoke pouring from the exhaust. I assumed it was just some water so I changed the oil today and it went away for a second l, then the smoke came right back...

Hey there, I’m having a problem with my 2008 Speed 3. When I’m travelling along the highway with cruise control on and I go on a slight incline, the engine begins to burble/misfire after that slight load is introduced. It doesn’t seem to do it under full boost conditions. Only just at low rpms...

Hey All, I just purchased some parts finally from Corksport. 3.5in intake, CBE, DP, AP V3, Fuel Internals, BOV, Turbo Inlet. My car is a 2011 Speed3, All Stock with 149K miles. I called a shop to tune the car and he is worried about rod stretching/failure and would really reconsider modding...

Hey everyone, New here. I have a 07 speed 3 with full bolt ons and i bought a 2nd gen motor from a friend and just got it hung in the car. I have a few questions. I know the block is the same, however I have realized PS pump is different along with AC compressor (they will be swapped). my...

Hello everyone new to the forums and the mazdaspeed life, I apologize if this has already been solved in another thread but I couldn't find it. I bought my speed a few weeks ago with Cobb intake, fuel pump internals, upgraded intercooler and turbo smart BOV. Yesterday I installed a Cobb turbo...

Got a whining sound in my 2007 MS3 GT. Car is fully warmed up, only whines while driving under load, approaching or at WOT load in all gears. Whines pitch does not increase or decrease. One coupler on the FMI popped off but that has been replaced with a new one + clamps, it pulls and boosts...

Here is how I attached the Harbor Freight Engine stand to the motor and it worked out well. Here is how I mounted it. You will need 3 threaded bolts m10x1.5 "length depends on stand" and 1 long thinner threaded bolt that you will but a nut on. The 3 go into bolt holes for the trans that are...
