Sorry for probably posting up duplicates of the same request from others but I am having an issue where it sounds like the TCT needs replacing but reading through the forums and listening to countless youtube "S2000 Engine Noise" I don't know where the issue is.

I took it to Motorsport Techniques here in Hayward Ca. asked them to see what was wrong, they were not able to find the issue and stated that it might be a valve adjustment. So I looked up valve adjustment. Great! the ticking noise is valve adjust or TCT which I can manage to do. But the issue i brought it in was for the sputtering noise, it seems like it lost power #1 and then the sputtering sound it makes when you press the gas(video above). That sound is not there when it's idle only in gear and most of the TCT and valve adjustments are when its idle.

Engine mods:
AP2 Transmission
87.25mm Mahle 11.71:1 pistons
Inline pro connecting rods
ACL rod bearings w/ OEM main bearings


Has anyone had this issue or heard the same sound it is making when you press on the gas? I'm hoping is not a huge problem.

Do a leak down and compression test. See if there's any issues there. Have someone who knows how to work on s2000 do a valve adjustment.

Yea I'm about to take it to blacktrax performance this week. They specialize in S2000 see if they can find the issue. Thanks!

I worked on a car that sounded like TCT at first. Turned out to be spun rod and all cam holder bolts loose. Compression check is a good first check and a worthy skill to learn.

Damn, that's what i'm afraid of..FML. I'm waiting for them to get back to me with an appointment now. Hopefully I get some type of result.

Rest assured if you are going to blacktrax. I have also taken my car there for work. Great group of guys
