This Nissan GTR came in for a modified bell housing and sport cat downpipes.
The bell housing on the GTR is not one of it’s best features and even OE replacements and revisions still have an issue with noise and vibration. The replacement unit we fitted here solves the issue with a relatively simple solution. New rear bearing is fixed position roller bearing design instead of the ball race bearing. The retention of the front bearing is also improved for increased strength.
The sport cat downpipes allow for a faster turbine spool up due to less back pressure, therefor increased power output is possible with less engine strain.
We did have an issue with removing the turbo’s, due to the vehicle’s age and many heat cycles, all but ONE exhaust stuf snapped on the way out. So we had to split the turbos to be able to get them onto our pillar drill safely, drill out the old studs to replace them with stronger studs with thread inserts.
You can see from the pictures we had fun working on this GTR.
We recently had to change the turbo’s on this diesel Range Rover, unfortunately the previous garage didn’t have the tools to carry out such a large and difficult task.
As you can see the ‘easiest’ way to get to the turbo’s is by lifting the entire body off!
