taikitanabe Posted January 17, 2017 Report Share Posted January 17, 2017 So I need to cut the trans tunnel for the shifter hole. Does anyone have any rough measurements to where the hole should be cut? Just need a general idea where to mark to cut the hole. Would it be in the similar location where the auto shifter is currently bolted to the trans tunnel? Thanks in advance! Quote Link to comment
Dolomite Posted January 17, 2017 Report Share Posted January 17, 2017 Bolt the manual and lift the tail till it touches the tunnel, mark and cut. That's what I did when I went from 4 to 5spd. 2 Quote Link to comment
Lockleaf Posted January 17, 2017 Report Share Posted January 17, 2017 What manual trans are you using? Quote Link to comment
taikitanabe Posted January 17, 2017 Author Report Share Posted January 17, 2017 I got a what I believe is a 280z 4spd. I'm not close to installing it yet, but I wanted to get a rough cut in before I spray in the Al's HNR around the trans tunnel. Quote Link to comment
qwik510 Posted January 19, 2017 Report Share Posted January 19, 2017 Wait until you find a 5 speed to install. The extra gear makes it so much more drivable on the road. Once you get a 5 speed, do as the others said. Bolt it to the bell housing, push the tailshaft up with a floor Jack and mark where the shifter will come through. Use a drill from the bottom and drill a hole up through the tunnel. Then Mark the cutout on the top and use a jigsaw to cut it out. Be careful of the brake lines that run through the tunnel. 1 Quote Link to comment
datzenmike Posted January 19, 2017 Report Share Posted January 19, 2017 I think you'll find the stock auto and the standard shifter comes out of the floor in about the same place. Measure back from the engine mounting surface on the transmission, to the shifter. Now measure back from the same place on the engine to the auto shift hole in the floor. Same? Quote Link to comment
taikitanabe Posted January 19, 2017 Author Report Share Posted January 19, 2017 lol stupid me! I didn't think about that! I'll measure tonight. Yeah, I just wanted a general idea where the hold was going to be so I didn't coat around that area. That'l give me something to work with. Quote Link to comment
datzenmike Posted January 19, 2017 Report Share Posted January 19, 2017 Does the tunnel top have a removable cover plate? The 521 does and can be unscrewed and moved to center the shifter hole. Quote Link to comment
