nickyboy Posted June 13, 2009 Report Posted June 13, 2009 (edited) why do you need to change to a t18 t50? i thought you couldn't use them plugged into 4a's :yes: nice looking car! numberplate back in the center though dude, its not a R31 lol Edited June 13, 2009 by nickyboy Quote
fusion Posted June 13, 2009 Author Report Posted June 13, 2009 (edited) Ah, stated above that I had already moved it back. It wasn't my thing and it was blocking the front indicator, so cops would of loved me. And I want to change to a T18 T50 in the hope that my speedo will be correct. I got one lying around, just need to swap the bellhousings over :yes: At the moment the speedo is out by 10% The picture above is from when I first got it pretty much. - Matt black stockys with retreads - Some mad clown stickering on the windows - Cut springs - Locked diff - License plates painted over and not in stock position So yeah, done a big clean up to get it all tidy again Cheers Fusion Edited June 13, 2009 by fusion Quote
trav_555 Posted June 13, 2009 Report Posted June 13, 2009 Yes but I'm pretty sure a t18 t50 wont bolt onto a 4a. Different amount of splines. However, can't you just take the speedo gear out of the t50 box and put it in the ae71 t50? Travis. Quote
machg Posted June 13, 2009 Report Posted June 13, 2009 Yes but I'm pretty sure a t18 t50 wont bolt onto a 4a. Different amount of splines. However, can't you just take the speedo gear out of the t50 box and put it in the ae71 t50? Travis. It depends on which model T18 the box came out of. Also the incorrect splining can be fixed by using the front half of the tailshaft that runs with that gearbox. The input shafts are the same, it's the output shafts that vary the number of splines.

trav_555 Posted June 13, 2009 Report Posted June 13, 2009 I see. Thats handy to know :yes: Cheers. Travis. Quote
dividee Posted June 13, 2009 Report Posted June 13, 2009 nice find man, minter. Probably one of the best colours for an ae71 me want :yes: Quote
toms.AE71 Posted June 14, 2009 Report Posted June 14, 2009 nice ride man very clean.. i reckon I'm gonna miss my 71 when it goe's :yes: Quote
fusion Posted June 14, 2009 Author Report Posted June 14, 2009 (edited) Cheers guys, its not in the greatest of condition paint wise, but it looks good from afar :yes: And cheers Machq thats exactly right. I have up to now used T50's from a TA22, T18 and AE71 so I am getting pretty familiar with them hahaha Just hoping that it might help the problem because it isn't fun always checking and calculating your speed Need to get some better pictures up Edited June 14, 2009 by fusion Quote
adam-__- Posted June 14, 2009 Report Posted June 14, 2009 Yeah, T18 boxes can be used with a 4A, just need to swap over bell housings and get a tail shaft to suit. What I don't understand is why the speedo would be out if it's an AE71 with an AE71 T50.. Fair enough if it was originally auto so the diff would change things, but I've got the same problem. :hmm: Took a T50 from an AE71 to put into my manual KE70 and the speedo is off by about 15% or so, slower. :yes: Quote
fusion Posted June 14, 2009 Author Report Posted June 14, 2009 (edited) About the only two factors that would come to mind would be the change in diff ratio (I think its different from AE71 borgy to T18 T-series, but not 100%) and the change in tyres / rims (13 x 5.5 to 14 x 6) that would change the final drive ratio Also I am no mechanic or knowledgeable person in this area, but the gear ratio in the gearbox may change it aswell, as that's where the speedo cable is connected (I think), although what I just said could be utter bull :yes: Edited June 14, 2009 by fusion Quote
tas_ae71 Posted June 14, 2009 Report Posted June 14, 2009 dude, check the tyre diameter ratio from std to the current. also the diff ratio maybe different to the std one. just swap the speedo gear drive thing from the t-18 one. A-series t-50's are better then T-series t50's. but id imagine ratios are the same between them. the throw to 5th is longer with the t-18 one. plus they all seem to be a bit more sloppy? Quote
machg Posted June 14, 2009 Report Posted June 14, 2009 I nearly got done speeding after a gearbox swap. I went from a TE72 T50 "small spline" to a (model unknown) "big spline" T50 and it knocked the speedo out by about 15 km/h! Quote
fusion Posted June 14, 2009 Author Report Posted June 14, 2009 I nearly got done speeding after a gearbox swap. I went from a TE72 T50 "small spline" to a (model unknown) "big spline" T50 and it knocked the speedo out by about 15 km/h! Yeah well, thats what I was worried about. However after using 2 GPS units and a couple of mates in their cars, we calculated it to be around 10% difference luckily. So it means 60kmph is actually 54kmph on the tacho. At first I thought everyone was just slow :yes: Quote
