Can anyone tell me what the top end speed is in the S4 and S5 and if theres limiters or not, for the 5 speed preferably

 

limited by power... nothing in the ecu.

non turbo around 120-130mph. turbo 150. thoses are close guesses....

 

I've heard 145 with the turbo but close enough.

 

Stock? No idea. My ITS prepped NA (essentially bolt ons that are pretty common) has run out to around 140 on several occasions. I'd guess it's good for a bit more but not much. Maybe 150 if you had enough room?

I had mine up to 148 mph at night with the lights up

 

On my old shitty 86 NA on route 65 in california I was doing ~140, but at that speed my steering wheel was vibrating so much I could barely hold on, then I got pulled over by CHP.

 

I have hit 160 in my 88T2 and no shaking at all ...felt like i was floating over the road...only problem is i ran out of road or i really could have seen top speed

 

 

haha ive only hit 130 in mine i know detiruch has hit 150 i the good old 86 base when it ran....

 

Yea, I figured a non-turbo could handle 140+, my 240sx can do about 130 maybe 135 before it runs out of power. Thanks for the info.
