The flywheel from what I researched. It was an exedy stage 1. The splines were partially stripped where the 5th gear is connected to the input shaft causing an awful rattle while cruising. The clutch splines were fine.

 

I regret selling my wing, leaving the holes in my trunk exposed, I regret selling my CAI, and I regret the day I decided lowering springs would be okay instead of coilovers

 

Carbonetics clutch kit. The shudder on takeoff was ridiculous, almost undriveable (I did put in a Fidanza flywheel at the same time, meaning I had to really balance the clutch pedal and rev a little higher on hills because of the low intertia/light weight). I got 70k out of the OEM clutch, and I have to say, after looking on here, I'll probably go back to OEM.

 

regret to change my steering wheel to momo f1, im missing the grip of the oem, i will put this back for sure.

 

No oem act extreme hd please. You'll love this clutch.

 

Biggest mod regret ever was the MAP EF2.5 I TRIED to have installed on my EVO IX MR after a fresh 2.0 full rebuild. The first turbo fell apart 250 miles after being installed, MAP misdiagnosed the failure, sent another turbo and it fell apart after 200 miles. This was 4 months ago. Since then my car has just been sitting, and waiting while my mechanic/tuner (KevinD) has sent them everything short of the entire car, and still no word as to what they are going to do. They have been trying to blame it on the brand new motor, but that's not the issue. Since then Kevin slapped a stock turbo he had laying around on the car just to get it running and back to me until this all gets sorted out. So far the stock turbo is rolling strong.

This all started after the motor gave out in january. I bought the car used, and did every bit of preventative and scheduled maintenance I could think of, but the question mark was always the internals of the motor. The previous owner didn't take very good care of the car at all, and it caught me out. My first EVO IX MR was bought brand new, and sold with 182,000 miles on the clock. It's now pushing 230k still on the original motor, transmission, and differentials. Pretty heavily modded, and still rolling strong. I never should have sold that car, but hopefully this one comes home soon. It's been almost 9 months now. 5 of that has been waiting on a turbo that won't completely fall apart after 250 miles.

 

I dont regret anything really, but I bought my car with the ACT 6 Puck and i loath the clutch. Cant wait to replace with an Exedy Twin or something of the sort. anyone have thoughts on the QM 8 leg?

 

I bought my Evo used with the parts listed in my signature (mostly), minus the ones underlined that are currently being fabbed up and installed. My regret is not immediately taking the car to a performance shop the first week I had it and having it checked out. Reason being is I had much more money on hand back in March when I got the car than I do now. I took the car to have it inspected about a month ago and all hot side parts pulled and coated and everything cleaned up. Turns out many small things were out of whack (FPR mounted directly on rail instead of firewall, hoses/cables/lines routed terribly, etc), turbo mani and o2 housing were cracked, badly leaking oil pan, and so on. Lesson learned is you don't know what you don't know but at the same time if I bought a used tuner car again, it will get checked out by a performance shop immediately. Thankfully Fathouse is taking care of my baby right now.

 

Cheap front lips on EBay

 

Like a lot of other people have mentioned: The only mod regret I have is trying 2 Fidanza clutches before I spent the money on my Exedy twin disk. I blew out 2 clutches in 1800 miles before I learned my lesson.

 

I regret not doing a balance shaft delete

 

Why? Did the belt break?

 

I'm not bashing FP turbos but worst mod ever was a FP Red journal turbo. I bought one when they first came out & it crapped out on me not once but twice. Again I'm not bashing FP Turbos cause one of the best turbos I ever had was a HTA3586R BB Turbo.

 

Modifying the car has been my biggest regret now that I am looking to move on to a different platform.

 

not getting a quality set of injectors..lucky there were not to bad i didnt damage anything..found out they were cutting out at high pressure when i had them sent in for cleaning..and it was a manufacturing defect in em..now rocking fic.
