I am just curious,has anyone else other than us had an issue with the APS turbo slightly hitting the steering knuckle when making a hard right turn? We installed 2 APS kits so far on 2 different 2003 early model Z's and had to grind down the knuckle on them and it still seems to bind up a bit..Anyone else heard of this or experienced it??

 

I recall during install that Adam had to remove very little material from the steering shaft joint... however it was a trivial ammount of material and I am almost positive that the APS manual told him this had to be done... so I would say yes this sounds normal.

However we have not experienced any binding or related clearance issues. Its a close one, but not too bad. I am not sure what could cause consistency issues other then possibly a vehicle that was in a bad collision... but since you have had 2 of them do it to you I can only assume that its YOUR FAULT! Just kidding. Take some pictures lets see whats going on and maybe we can figure something out.

Or maybe you need to slide the joint down more... it wouldnt be hard to have the joint higher up than normal since I do not believe it would effect its function at all... cant recall exactly how much room to play there is there.

 

The instructions have a detailed diagram of the edge of the shaft clamping flange that needs to be ground down. Is this the area you are referring to. It's on their site in the instruction download section.

 

I know, where the ones that gave APS that info.but we did it on 2 cars and one had no problem for a few thousand miles and now its starting to bind and the other one i guess we just didnt grind enough material.we were just looking to see if anyone else had the same issues as APS denied it being an issue to us since the beginning, and their original instructions did not have this piece of info.

 

I wonder if the motor mounts are up to the huge torque increases.....maybe they have started to deform under the high stress loads and have allowed the motor to shift slightly. Just a thought.

 

This was out thought..We had a wrecked 350Z in the yard we took one of our motors from and the two motor mounts were sheared right off from the ompact..

 

Maybe eurethane motor mounts are the next mod for TT cars?? I sent an e-mail off to Energy Suspension to see what they say. They have mounts for many domestics, Honda's etc.
