ok guys.. i just decided on the m2 twin upgrade... my stock twins have 130,000 + so i think i'm gonna need to pick it up next year... ok so my question is..... should i still go with a fmic or should i go with a smic?.. i know the smic is better in cooling cause it allows the radiator to get all the fresh air from the nose...but is it gonna good enough??? and also how many psi can i run safely on 91 octane.. that's the highest they have here in the bay area....

 

i wouldnt go over 16-17psi on pump gas, either ic setup will work, the one you use will kinda depend on how you use the car. if its for road racing you prolly wanna look at the stock mount, if you are drag racing the front mount is better. on the street they both have strenghts and weaknesses
