4.6 install easier than 3 4 5 close? Quicker acceleration with kaaz final or 3 4 5 set? Maybe shortening 1st gear I suffer more wheel spin at launch? Lsd suggested to improve traction? I don't do autocross. City drive, once a year highway, trackday at Magione Umbria Circuit 0.4 miles main straight. From my data 6mph more with 4.6 than 3.4.5 close. Not a difference. Price alike. Same work expense to me. Still I don't understand which one allows more and quicker acceleration. By your words it seems to be 4.6 then 3 4 5 only for long roads, finally best all together. If I had 3 wheels I'd be barrow.. typical italian humour. Seriously I don't like stock 4th length. kaaz 3 4 5 closes all five gears. Please tell me if 4.6 quicker than 3 4 5 close. Or don't 3 4 5 make car quicker but only less speedy? Thank u. |

Yes, but if you can do one, you can do both.
Quicker in all gears with final drive. Only quicker in 3,4,5 with gearset. Yes, this may happen, you can launch in 2'nd if needed. The LSD will help with this also. Yes, this is strongly recommended! Quote:
1. Only 4.6 FD with Kaaz LSD or 2. 4.3 FD and 3,4,5 gearset and Kaaz LSD The 4.6 may be exactly what you're looking for and should be a very nice improvement. The 4.6 will be more noticeable in all gears.

I see on kaaz site there's short gear set for 6 gear C60. Is it possible to take 1st to 5th and install to C56? Some matter using with C56 shafts? Maybe case work needed? Thank u man.

So you propose putting the gears from a C50 (Yaris) into a C56, or the other way around? I'm working on a gearbox that has parts from a C50, C56 and C59. It seems to go together, but I haven't tried setting the bearing pre-load on the differential. http://www.yarisworld.com/forums/sho...d.php?p=700882 |

my 2003 japanese vitz rs (echo hatch in US) has kaaz 1zz gear set + final. It should be C56. I had to instal kaaz shafts and 1zz diff to fit final e 1zz hub to fit 3rd e 4td.
It should be C56. Trd made, now discontinued, same close gears for C52 4age black and C56 4age silver if I'm not wrong. Trd gear set is same as celica kaaz from 1st to 5th. This is why I wonder I can swap onto my gearbox. I'm not sure, only I wonder. Maybe u know. Last edited by speed1; 10-16-2013 at 01:19 AM. |
