with a 4.9 FD.
This motor would have a much fatter powerband, and lots more TQ. Its basically an H22 with the R/S of a GSR. Im not sure on the 270 estimate. Id expect 260 with Jenveys. Toda IIRC far too small for this disp motor unless kenny has tricked out versions...............
This motor kinda needs the baller ITBs, but theres probably an intake setup good enough for it. Kens had ITBs since before they were "cool".
