gts4 diff ratio

[stacy]

Anyone know if auto and manual gts4's run the same diff ratio? I need to find a new front diff for the cefiro and need to know if I have to use an auto one, unless I also swap the rear. Fire wall plate says rc43 so guessing it has a 4.3:1 there at the moment

[32]

gts4s are 4.3 regardless of trans
gts/gtst are also 4.3 regardless
gts25 manual are 4.3 auto are 3.9
diesel laurel are 3.5 regardless
gtr are 4.1

I may have mixed up diesel and gts25 auto ratios

cheers man, exactly what I wanted to hear!

better do some more homework be 4 you wreak your transfer box as some of that info is incorrect

[32]

care to correct me then instead of being a smartass?

[r32rb30det]

who's being a smart ass as im not trying to be. I would hate to be given the incorrect info and it cost a lot of money in the long run. im not sure about other models but I know the r32gtst auto diff is differnt ratio from the manual diff ratio and from what I have read in the past I thank (but not sure) other 2wd models are the same. as for the 4wd models im not sure they may be the same from the auto to manual. If any one knows the correct info please post it on this subject.

32 please don't get upset if people have other info thats differnt to yours

Actually my transfer case is already stuffed due to the front diff smashing its internals up and locking up the driveshaft from the transfer case. Luck would have it that it did this rather than lock up the driveshafts to the wheels so I can still use it. I belive the info I needed is correct above, ie auto/manual turbo ratio as I have checked a genuine r32 5 speed turbo out and have found that it and my formally auto both have RC43 on the blue plates on the firewall, this should didctate it running a 4.3 ratio diff. Correct me if im wrong.

Well perhaps you should have just given her your info instead of telling her to do her homework. And despite what you think you have READ in the past, I have actually discovered these ratios on the various vehicles I have owned and worked on.
