Supra Gaz Posted March 16, 2011 Share Posted March 16, 2011 I have bought a conversion kit from Keron to convert my auto na to a 5 speed manual. Does anyone know what is required? Is there any cutting and welding of the transmission tunnel? Has anyone done it before? I did use the old search button but nothing exact came up Cheers Quote Link to comment Share on other sites More sharing options...

EMPEROR Posted March 17, 2011 Share Posted March 17, 2011 Yes, auto and manual tunnels are different... Other then that I think you might need to do some rewiring for the speed sensor and the reverse light (but I am not a 100% sure about that).

Supra Gaz Posted March 17, 2011 Author Share Posted March 17, 2011 So I'm right in assuming this is a huge pig of a job? Quote Link to comment Share on other sites More sharing options...
Homer Posted March 17, 2011 Share Posted March 17, 2011 It's not as bad as it sounds. You don't actually cut the tunnel itself, there's a secondary plate that needs to be removed and replaced with the manual one. It's spot welded and bonded into place underneath the trans tunnel, the spot welds need to be drilled out and the bonding chiselled away. The new plate can be bolted & bonded into place (or spot welded if you have one). There's some pics of the conversion here: http://www.mkivsupra.net/vbb/showthread.php?139393-My-new-Supra-rebuilding-Dude-s-drag-car&p=2011470&viewfull=1#post2011470 Edit - if the link doesn't work, do to post 333 in the thread If you have any questions, just ask Quote Link to comment Share on other sites More sharing options...
Supra Gaz Posted March 17, 2011 Author Share Posted March 17, 2011 Cheers for that, I am weighing up having my na auto converted, I have the w58 conversion kit from keron on the way to afr now. I will see what costs are involved and go from there, it may be worth selling up and buying a manual. Cheers Quote Link to comment Share on other sites More sharing options...
Homer Posted March 17, 2011 Share Posted March 17, 2011 Auto to 5spd conversion on an NA is far simpler than other manual conversions since the diff doesn't have to be messed about with - it's pretty much plug and play apart from the tunnel mod. I doubt the costs will be too high as it's a relatively simple job. It's about a days work. I did the tunnel mod, clocks change, pedal swap, clutch master and slave install in about 4 hours, so add 3 hours to change the box, then an hour to test everything out you won't be too far off.

Supra Gaz Posted March 18, 2011 Author Share Posted March 18, 2011 I have been talking to john about it at AFR, he is saying I need the bit that is rivetted on? I'm not sure what he means by that. Do you have an idea? Its looking pretty pricey at the moment, around 600 quid labour. John and the guys are some of the best but is that amount right?
