    I recently got an Endeavor plastic intake and its pretty impressive. It makes the 3.8 mivec intake look tiny. It has the same diameter runners as the mivec, but they are 3” longer. The plastic is smoother inside. The lower intake has a lot of potential also. The throttle bodies look very...

    Does anyone have a trans mount for a 3,8L 6 speed for sale? I have the energy suspension poly bushings but when I installed it, I followed the directions not realizing the directions are for the 3g cuz it also works with the 4g 3.8 6 speed only from Auto city imports so I removed the bushing...

    Hey, I'm getting a clutch (FX100) and steel flywheel put in on a stock Eclipse GT (ish). Figured it might be a good time to get a differential installed since I'm having a shop work on it...

    Has anyone had any experience with removing the input and output shaft speed sensor on an automatic transmission? Engine is a 3.8.

    Hey guys quick question, for the 3.8 is it necessary to remove the splash guards under the car and the front bumper to fully remove the radiator, or can I just simply remove and replace from the top?

    So I've been looking around the forum for a couple hours to no avail. I'm looking into getting OBX headers for my 3.8 (RRE is a little expensive for me BUT I know it's quality stuff). However, there are two versions of the OBX headers. The first has longer flex tubes while the second has shorter...

    The other day I went and test drove an 08 Spyder GT MT. I currently drive a 2017 Ford Fusion with the 2.0 turbo, for comparison. It felt a lot slower than I expected. It was fun regardless, but it didn't feel much faster than my Fusion. I expected a lot more oomph. More pull. More torque. The...

    Hey guys, so I recently bought a 2008 Mitsubishi Endeavor because I found it really fun to drive compared to other Suvs. After a little research I found that the Endeavor runs a 3.8 L 6G75 SOHC 24v V6 which from what I can tell is the same engine the Eclipse runs. The difference is The Eclipse...

    I have a 3.8 mivec in an other than Mitsubishi car. I am trying to get the mivec solenoid working and I’m wondering how noticeable is it when it kicks on? I think it supposed to be at around 4000 rpms. Is that the correct rpms? Has anyone tried changing the rpms?

    Has anyone modified the mivec rockers on a 3.8 to create more valve lift? It looks pretty complicated to me, but I thought there might be something simple to do.

    I have installed an 09 3.8 Mivec in a non Mitsubishi car. The motor runs great, but is not idling that well. Is it possible that the solenoid can be stuck on? It’s not even hooked up currently. I had to get the solenoid from another car that was wrecked pretty good in the front. I think I may be...
  18. 4G Eclipse GT/SE Specific
    Im assembling an 09 3.8 Mivec and I’m have trouble finding the torque specs on the connecting rods. The 3.0 and 3.5’s say 37-38 ft/lbs. The 3.8 says like 20 ft/lbs. That doesn’t sound right. I’m assuming there is something I’m missing. I think the mains are supposed to be 74 ft/lbs, but there...

    Greetings, I have a 2007 Eclipse Spyder 3.8. It ran fine a few days ago. Today it cranks but has no spark and no pulse to fuel injectors. There is supply voltage at the injectors and ignition coils. There is also a pulse from the crank sensor to the ECU. Any suggestions? Thank you.
