Jatco 4N71B Transmission Update


240Z Turbo

Recommended Posts

As some have read the twinturbo went 11.2@130mph yesterday night. As you may know I used stock bands and OEM clutches and the trans seems to hold up just fine with no complications. The MPH calculates into about 474hp@wheels. Now, I was bouncing off the rev limiter through the traps with 7200rpm in 3rd(1:1 ratio). All 3 runs I floored the car were between 129.4-129.7mph, but 7200rpm in 3rd(1:1) with a 26" tire translates into 150mph. So, I am losing about 20mph because of converter slippage. Those who have considered the swap can now see what type of power the Jatco trans can handle. I will be sending the converter off sometime soon to have it evaluated. I am hoping that if the converter can be more efficient the car can run atleast 140mph with some further boost and tuning. Will keep you updated.
