JUN is showing their new 4.0 liter stroker kit for the VR38DETT at the 2009 SEMA Show in Las Vegas. There is no replacement for displacement, and this looks like a good way to bump the 3.8 up to 4.0 liters. We can’t wait to see some results with the kits, and other modifications coming for the R35 soon. Bore and stroke ? Well we asked but didn’t get an answer in the JUN booth.
