I picked up a nice little 2003 350GT-8 with a buggered CVT gearbox, I fitted a secondhand CVT gearbox but was unable to rectify the faults.
After about 1 year of spending time trying to find the faults, I decided I would make the leap and convert the sedan to a 6MT from a 350Z.
Please try and refrain from writing things like "WHY DIDNT YOU JUST BUY A MANUAL TO START WITH" etc etc. I don't care.
The car cost me $1500 licensed and all, and 2k for the conversion. Still cheaper than buying a 350 6MT.
This post will contain as many photos as possible as I progress through the build. This will be continually updated as I complete the stages.
I have never been able to find out about mounting the handbrake lever, or the legalities on cutting the transmission tunnel out to fit the gearbox. I hope to provide some light on these matters for the next person to take on the conversion project.
Removed CVT and threw it in the skip bin. Best feeling of my life. GOOD RIDDANCE.
Removed the following;
Carpet (needed a clean anyway)
Front and rear seats
HVAC and anything in my way
Airbag module, Gyro & Traction control module. (NOTE ANYTHING WITH YELLOW PLUGS IS SRS AIRBAGS, MAKE SURE BATTERY UNPLUGGED ALSO DO NOT FLIP OVER THE SRS MODULE FROM UNDER THE CONSOLE, IF YOUR BATTERY IS CONNECTED OR IT HAS CHARGE IT WILL SET OFF YOUR AIRBAGS. IVE SEEN IT DONE. VERY DANGEROUS.)
Brackets and really anything you see is going to slow you down.
Mock fitted the console and handbrake assembly to see the alignment. Measured gearbox to the tunnel.
Pictures of the handbrake assembly and how it DOES NOT match anything on the original tunnel, I guess you could make up a few brackets and cut some holes but that is dodgy and I want this thing to be as good as factory when I am done.
I have a manual tunnel from a 350Z, I have decided to remove the inner skin that has the moulding for the manual trans and the handbrake that I require. Once done will be as simple as bolting it all onto the new inner skin as per factory.
I was able to drill out the spot welds with a Spot weld cutter available for $20 its like a little hole saw. I have a qualified boilermaker / engineer on hand to weld the skin into the cars existing tunnel.
There are A LOT of little spot welds not marked with arrows, the arrows are just pointing out a few of the ones I started to cut out.
More photos and info to come! Thanks
