mikeyb10supra Posted January 9, 2008 Share Posted January 9, 2008 Maybe one for the N/A-T boys or anyone else for that matter that may want to chip in, im considering doing a 5-speed swap into my TT and uprating the clutch, flywheel etc. My question is, and maybe Chris Wilson or digsy can chip in for this....can it be significantly stregthened...ie to hold a small single and when I mean small, im talking about a gt30 or similar on a cast manifold??

tooquicktostop Posted January 9, 2008 Share Posted January 9, 2008 Will be a whole lot cheaper than a 6 speed conversion and with 'lower' power levels should be ok I would have thought if well maintained, I have never driven the Supra 5 speed but I have always felt the 6 speed while very strong was always a gear to many and was really a fashion statement as much as anything else, When I think of the 5 speed in my R32 GTR the length of time in one gear is much longer and allows crummy drives like me a chance to get some power down Link to comment Share on other sites More sharing options...

tooquicktostop Posted January 9, 2008 Share Posted January 9, 2008 A certain TF fitted a high ratio diff by mistake when I had my six speed conversion done (its changed now) this gave the car huge acceleration but at the pod day I was grabbing 5th gear with 300 yards to go and knew something was wrong, however the accleration off the line was very good and I would imagine the 5 speed box would have a similar effect as the second and third gear would be much longer ?

mikeyb10supra Posted January 9, 2008 Author Share Posted January 9, 2008 I think I might look into this route then....seems like a good idea if it gives the car some extra poke off the line, and with the gt30 should make an interesting road car Link to comment Share on other sites More sharing options...
steve spedd Posted January 9, 2008 Share Posted January 9, 2008 I think the best person to talk to is Gaz (GazzGSI) he was running an NA-T with 400+ and had the W58 strengthened. Not sure who did it but worth asking him?? Link to comment Share on other sites More sharing options...
Chris Wilson Posted January 9, 2008 Share Posted January 9, 2008 It'd almost certainly cost more than buying a Getrag box and supporting bits and pieces. I think there are some straight cut, dog box internals for that casing, but it would be dire to use in a road car. Link to comment Share on other sites More sharing options...
miko_supra Posted January 9, 2008 Share Posted January 9, 2008 bromy has told me that he is running 400bhp n/a-t through his box and has covered 16k miles in two years with no issues. im running stock tt power through mine and it feels strong enough at the moment. just have to see what happens when i go bpu in the spring. the americans say it can handle 450bhp (but you know what they are like with figures) Link to comment Share on other sites More sharing options...
dini_the_owl Posted January 9, 2008 Share Posted January 9, 2008 i know people who run w58's with over 400 with no problems. i was quoted £89 for an input shaft bearing from mr t in my old w58 and i got the exact same bearing from derby bearings for £35 so the cost soon mounts up when replacing other bits like synchromesh's etc....id get some use out of the 5spd 1st at least till it dropped to its knees and died, i must admit i liked the 5spd in my tt Link to comment Share on other sites More sharing options...
Chris Wilson Posted January 10, 2008 Share Posted January 10, 2008 Found my Bookmark, here you go: http://www.ppgearbox.com.au/files/pdfs/PPG%20Product%20List%20May%2007.pdf I have used their Skyline kits, and their RX-7 ones, and they are excellent for the price. Not Xtrac or Hewland, but good value. Link to comment Share on other sites More sharing options...
