UltraFlynn Posted August 2, 2008 Share Posted August 2, 2008 Does anyone know whether the 6-speed manual box fitted to some SZ-Rs is the same unit as the one fitted to the TT? Link to comment Share on other sites More sharing options...
Ric Posted August 2, 2008 Share Posted August 2, 2008 its the V161 rather than the V160, its "pretty" much the same afaik am sure sombody who knows more will have some input Link to comment Share on other sites More sharing options...
UltraFlynn Posted August 2, 2008 Author Share Posted August 2, 2008 I'd be interested to know the difference between a V160 and V161. I wonder if they can handle the same power. (I would imagine not considering it's specced to fit the NA) Link to comment Share on other sites More sharing options...
Guigsy Posted August 2, 2008 Share Posted August 2, 2008 the ratios are very slightly different i think. Wasnt the uk spec 6 speed the 161? or am i making that up Link to comment Share on other sites More sharing options...
UltraFlynn Posted August 2, 2008 Author Share Posted August 2, 2008 The reason I ask is that I'm going to have a 6-speed SZ-R imported in the near future and my long-term plans are to drop in a more powerful engine in maybe 2 or 3 years time. I'd like to know that the transmission is going to be able to handle about 500bhp, which I know the V160 will. Link to comment Share on other sites More sharing options...
Homer Posted August 2, 2008 Share Posted August 2, 2008 I'd be interested to know the difference between a V160 and V161. I wonder if they can handle the same power. (I would imagine not considering it's specced to fit the NA) Just the ratio's and apparently an uprated sync gear. They are as stong, if not stronger than the V160. They were also fitted to the TT's of the same age. Details here on the ratios: http://www.mkivsupra.net/vbb/showpost.php?p=1167781&postcount=8 Link to comment Share on other sites More sharing options...
UltraFlynn Posted August 2, 2008 Author Share Posted August 2, 2008 Hey, that's great news. That's for the info. I have a question about gear ratios though, What difference will the Diff/Final Drive ratio make if the UK TT has 3.133 and NA 3.769? What affect does that actually have? (Please excuse my ignorance on this) Link to comment Share on other sites More sharing options...

(Please excuse my ignorance on this) Again, Alex has done the hard work on this: http://www.mkivsupra.net/vbb/showthread.php?t=29830 Very useful links these! Basically, the closer the diff ratio is to 1:1, the higher the speed in each gear, at the cost of acceleration, the further away, the quicker the acceleration, at the cost of speed in each gear Link to comment Share on other sites More sharing options...
UltraFlynn Posted August 2, 2008 Author Share Posted August 2, 2008 Once again, many thanks. I've got this sneaking suspicion that I could have saved a thread and used the search button. Link to comment Share on other sites More sharing options...

Scooter Posted August 2, 2008 Share Posted August 2, 2008 it will max out at 'low' speed........ The ratios of a NA are set to best use the relatively low power available.......ie there is no point having gearing to allow almost 200mph (like the TT has) when the engine can only really power it to 150ish mph. So if you don't adjust the diff on your NA you will be bouncing off the limiter in 6th at 150-155mph, and the time spent in the gears gettign there will be short, 1st will be a handful (its bad enough in stock TT's) and 2nd 3rd and 4th will go in the blink of an eye if you plant your foot, you'll be forever changing gear i'd imagine Note whilst the gearbox is the same the clutch and flywheel aren't afaik.

UltraFlynn Posted August 2, 2008 Author Share Posted August 2, 2008 Clutch and flywheel I would expect to change with a much more powerful engine. It's interesting to know that I'd also need to consider changing the diff as well if I want to maximise the top speed. Link to comment Share on other sites More sharing options...
Homer Posted August 2, 2008 Share Posted August 2, 2008 Note whilst the gearbox is the same the clutch and flywheel aren't afaik. The same question was asked quite recently and I believe the conclusion from a couple of people was that the clutch and flywheel on the V161 SZ-R is the same as the one used in the TT's. I don't know one way or the other, but just recall seeing it mentioned a couple of times. Link to comment Share on other sites More sharing options...

Homer Posted August 2, 2008 Share Posted August 2, 2008 Oops, time for me to backtrack It's strange as the people in the know seemed to get it wrong and the source of the information although from one of the better members here, doesn't identify it's source: http://www.mkivsupra.net/vbb/showthread.php?t=138104&highlight=v161+clutch Link to comment Share on other sites More sharing options...
colsoop Posted August 3, 2008 Share Posted August 3, 2008 I don't know if its any help but i checked the EPC and the clutch cover and disc assembly for the NA are different part numbers to the TT. The flywheels are the same. Link to comment Share on other sites More sharing options...
UltraFlynn Posted August 3, 2008 Author Share Posted August 3, 2008 Thanks for that. That backs up what was in that link, that the flywheel is the same as the TT but the clutch different. Link to comment Share on other sites More sharing options...
