I'm going to jump in again. My biggest concern about any of this is "case by case basis". That is absolute BS!!!
Future quote; "You let the JDM XYZ in, but MY Euro ZYX can't! Thats not fair!"
People are screaming for a stable rule set, but than we are looking at a case by case basis on JDM (yo) and Euro/Aussie etc. So when the Euro surprise shows up and kicks their ass, than it gets booted or a trailer attached to it. Not very stable!! We are very familiar with the USDM engines and their potential, lets leave it at that.
I can understand the arguement regarding a worthwhile Nissan engine or whatever, but maybe its time for another car or class.
I have seen( actually looked at numbers) the S42, a 315 HP 2l exotic. a M52B20? ( I believe) its a 2l version of the 2.5l BMW motor used in a million e30s and e36s, 8500 rpm 6 cylinder. I was talking with a BMW nerd, and he brought up like 5 motors most have never heard of, all under 2l all with crazy hp numbers.
Rant off, I gotta go add 90 lbs to my car now!!
