Afternoon all,

Another day, another problem, recently finished my turbo conversion on my 1.8 93 enous. This problem all started after I had the car mapped.

When I put my foot down and accelerate hard, from about 5k revs onwards and at high speeds I am getting a very rough grinding/vibration but I cannot put my finger on it, the noise goes away if I put my foot on the clutch, lift up and it comes straight back.

Absolutely no noise under 70 mph or cruising a low revs.

When doing the conversion the engine was out, changed the clutch to an XTD stage 2 with a new clutch release bearing.

Ideas anyone?

Cheers

Forgot to add, had the car up and cannot notice anything obvious rubbing anywhere

Id start with seeing if the exhaust is contacting the chassis when the drivetrain is torqued over under load. Start with the simple stuff first.

I was going to guess motor mounts allowing something to contact.

thanks guys, with motor mounts what would you check on that?

im going to have another look tomorrow however before I read this I noticed the rear baffle on the straight (before the backbox) is touching a chassis bar but I didn't see any obvious marks on the exhaust or chassis, I will try moving it or wedging some rubber in there tomorrow and see if it eliminates the problem
