i'm planning on fully building my type r this winter......but before then, i want to throw a little bit of nitrous to it just for this summer just so it's a little different than it was last year.....i have the AEM plug and play ECU, so what's the largest shot i can run to it safely, on a regular basis?

 

I wouldn't go any higher than 25, because then your gonna want to try 50. And if I say 75 your going wonder what it would be like to try a 100 and then you may blow your motor. So start w/25 but no more than 75.
