The H25 is a very long stroke 4 cylinder, probably too long for a sports car
motor. I run an H20 and it's great. Big 4 cylinders aren't the best running
motors unless they use balance shafts. See Porsche 944s and Mitsubishi
Starions

You can't use a H head as it's very restrictive. I have one and it serves as
a great paper weight. Mine has a 2 bolt housing but can't be used on a
Roadster head as the outlet angle is wrong as it faces the rear. You need a
water outlet from a 1500 or 411.

 I had to modify mine by drilling additional holes in the rad braces.

the 1600 rad.

I just brought my old 1600 rad in to have a neck put on the header tank and
have the overflow outlet changed to a 2L type.
