hodge Posted September 10, 2008 Share Posted September 10, 2008 Has anyone done this and are they any good for the power or is it a total no no. Quote Link to comment Share on other sites More sharing options...
Guigsy Posted September 10, 2008 Share Posted September 10, 2008 as long as its not single they tend to last quite a while apparently. Quote Link to comment Share on other sites More sharing options...
Luka-P Posted September 10, 2008 Share Posted September 10, 2008 Alot of people who convert from NA to TT stick with their 5 speed box, if not originally auto. It is good to BPU stage and is said to have a better ratio IIRC. Quote Link to comment Share on other sites More sharing options...
couv3z Posted September 10, 2008 Share Posted September 10, 2008 its more for a TT lump into a 5 speed, when us na people drop a tt lump in they ment to be good to 500bhp but i have heard of someone whith 600 with a 5-speed Quote Link to comment Share on other sites More sharing options...
Jim_1979 Posted September 10, 2008 Share Posted September 10, 2008 I've been talking with keron about getting a 5speed setup, but he has none at the moment. Alot cheaper than 6speed also. Quote Link to comment Share on other sites More sharing options...
bigbloodyturbo Posted September 10, 2008 Share Posted September 10, 2008 i'm thinking about an R154 conversion, how much do w58's usually go for? Quote Link to comment Share on other sites More sharing options...
Homer Posted September 10, 2008 Share Posted September 10, 2008 The gear ratio is not ideal so it runs out of steam easily if you like motorway runs. The final drive on the TT's is much lower as you don't want to be sat on an A or M road with the turbo's in positive boost area every time you squeeze the pedal, that wouldn't be nice on fuel economy. But yes, with a clutch change it can and has been done. If it has one, I highly recommend changing the open diff for an auto LSD, it'll bring the final drive ratio down and allow you to get the power down. BPU TT and open diff is NOT nice to drive!

Homer Posted September 10, 2008 Share Posted September 10, 2008 i'm thinking about an R154 conversion, how much do w58's usually go for? Got mine for £80. Quote Link to comment Share on other sites More sharing options...
Jim_1979 Posted September 10, 2008 Share Posted September 10, 2008 Q.... What's a R154 and what's a W58? Quote Link to comment Share on other sites More sharing options...
Konrad Posted September 10, 2008 Share Posted September 10, 2008 R154 is gearbox used in MK3 Supras, very strong W58 is 5speed manual gearbox for Supra MK4 NA Quote Link to comment Share on other sites More sharing options...
Homer Posted September 10, 2008 Share Posted September 10, 2008 W58 is 5speed manual gearbox for Supra MK4 NA And not quite as strong as the R154 Quote Link to comment Share on other sites More sharing options...
bigbloodyturbo Posted September 10, 2008 Share Posted September 10, 2008 if you can find them the r154 from a soarer is a drop in job. R154 from a mk3 is easy to find but needs some work to make it fit. The clutch from a mk3 will fit aswell which is cheaper than the clutch for a 6 speed.

bigbloodyturbo Posted September 10, 2008 Share Posted September 10, 2008 soarer has a longer shifter housing than the mk3 has, the mk3 box has the shifter to far forwards and needs extended. the soarer came in two flavours as far as im aware, one with an actual extended shifter housing and one with the standard shifter housing but with a swan neck shifter so it sat in the correct postion. Their both physically the same transmission. Quote Link to comment Share on other sites More sharing options...
dibbleyuk Posted September 10, 2008 Share Posted September 10, 2008 (edited) I run mine whichs is BPU+ on the 5speed box and am very happy with it first gear is pointless lol 2nd gear lights up the rears with out any problems in the dry! so you have to feed the power dont just floor it, 3rd and 4th are awsome you can really feel the sheer power! Only thing is it can hit the limiter in 5th gear in less that 30seconds but then again you would be doing around 160leptons so not to shy you just no it has more to go as it pulls so hard to that speed.

bigbloodyturbo Posted September 10, 2008 Share Posted September 10, 2008 was that with a w58? did you have an LSD installed with it? LSD will be harder on it Quote Link to comment Share on other sites More sharing options...
dibbleyuk Posted September 10, 2008 Share Posted September 10, 2008 was that with a w58? did you have an LSD installed with it? LSD will be harder on it My NA was one of the few that came with the LSD as standard so i done the TT conversion and kept the W58 box and LSD on there it seems to be a good setup i like it alot ive done 2000miles since its been done and have givin it quite abit of abuse at times at 1.2bar and i havnt had any problems yet so hopefully it will hold out.

David Reid Posted September 10, 2008 Share Posted September 10, 2008 Does anyone have details about what is needed to be done to extend the shifter when using the R154 this is the package I will be fitting with a nice single. Quote Link to comment Share on other sites More sharing options...
bigbloodyturbo Posted September 10, 2008 Share Posted September 10, 2008 thats good to hear, i might go with a w58 myself, was going to hold off for a r154 swap next year but from what you and a couple others say the w58 seems to hold bpu power quite well.

All i was told was to not slam it into the gears or crunch them thats they only way you can really cause a problem if you respect the fact the car is running alot of power and dont abuse the w58 box it should hold the power for a long time.

David Reid Posted September 10, 2008 Share Posted September 10, 2008 i have the toyota part numbers if you need them Yes please, I take it there is a bolt on extension from toyota I can use then? Do I also need the chassis number for a Mk3 supra to order it? Thanks Quote Link to comment Share on other sites More sharing options...
bigbloodyturbo Posted September 10, 2008 Share Posted September 10, 2008 Housing, Shifter (33521-24040) Control Shift Lever (33570-24010) These part numbers are Australian i think, i noted them from a thread i seen ages ago. It is basically the shifter housing and the shifter from a soarer box which bolts onto the r154 (6bolt i think) Quote Link to comment Share on other sites More sharing options...
cwtt Posted September 10, 2008 Share Posted September 10, 2008 It really depends on how much power you want to make. The V160 (6speed) is far superior to the 5spd. The 6spd can take any amount of power you make. But it is also very expensive. If you are not going to make much power (BPU) than the R154 would be just fine.

AndyT Posted September 10, 2008 Share Posted September 10, 2008 Future proof it and go 6 speed. You know you're gonna want more power 12 months in the future. Quote Link to comment Share on other sites More sharing options...
