Learn something new everyday. Never seen anything but S3R in USA. Checked stock and there are 2 sets of the Tomei in USA stock tho.

i have a RR block and B15 LSD transmission that I picked up from a friend for $600 for both (not each totalling $1200, but actually only $600 for both)

I wanted to get SR16VE pistons, VE head and so-on so-forth.. people were talking me out of it... I know the 20VE would be easier, but the fun of building the motor was what I found appealing. and I got the RR block for so darn cheap!!

it only has 60k miles on it.. really, it was practically a free block.. because the transmission is easily worth the $600 alone.

my recommendation is to sell the RR head and put a high port head on that RR motor with 4CW crank and high CR SR16 pistons then you can use 270 degree cams and the head is better due to the straight and long intake ports

High port heads don't flow as much as his engine would so his head would be worse than before if he put a high port on there.

I thought the RR came with 4CW crank... Hmmm so much to research.. Argh

LOL, I was in the shower thinking about that very thing. I am 75% sure they came with a 4 CW crank.
