Fellas,
When my swap was done, used 5s tranny with the input shafts as well, they currently have 278,000 KMs on them, and I'm getting a little worried throwing 280-300hp at them.....does anyone have any suggestions as to beefier axles I could swap into the 5s Tranny, it is full front wheel drive, if nothing can be swapped I'n, would it be a good idea to buy new stock axles for this Tranny??? Can't find a stage 1 or 2 axle anywhere for the 5s Tranny!!!
Your input is vital thank you.....Josh

6GC RULES!!!!!

pressure ran the stock axles and tranny for years at 300HP. im about to do a 1MZ swap and still use the S54 so im not concerned

I bought some replacement axles from Advance Auto, they're etched with "Made in Japan" and they're bigger than the OEM axles (32mm nut vs 30mm nut on OEM)... I think OEM axles are fine for turbo applications, and will probably handle past 300HP. The axles nor the transmission will limit you at or below 350hp guaranteed.

Of course that is assuming your axles are fine and dandy in the first place...

So far so good, I like what I'm hearing guys, the input shafts do seem to be I'n good shape, the higher mileage is starting to scare me though, but I guess steel is steel, and they would have snapped under load by now, if they wernt good enough....
Good to know...

My holding up so far, Dyno 311whp @ 14 psi, with S54 tranny, and a very harsh ACT 4 puck unsprung. Hopefully to break 400whp, then will see what happen then.

Awesome!
