Soo my current mods are k&n typhoon cai, 2.5" tsudo, 3" zzp DP, and a bad mab shorty header. I've heard the zzp tune is ass so I'm not going to get stage 2 kit. I'm going to buy plugs, 60 injectors, stage 2 belt and 2.9" pulley. My question is, do I need to buy either a dual pass or A heat exchanger to run that pulley or should I just get the 3".

 

I'm asking bc I don't have money to buy cooling mods right now but don't wanna get a 2.9 if I have to get cooling mods.

 

You'll be fine

 

You'll be fine with a 2.9 pulley. Once you drop below that, I would start gathering up some more cooling mods.

 

Okay cool. One more question. I will need a pulley puller tool to remove stock pulley then won't need it anymore when I get the modular pulley huh, right?

 

Yes, you will need a puller to pull it off, and to put the modular hub back on. Then from there it's simple to change the pulley!

 

Awesome, thanks man.

 

Cooling mods are far too over rated. It depends what you like to do with the car.

 

i agree with blue lightning
ive been on stock cooling and a 2.8 inch pulley for a year now. and one more year of a 3 inch. no problems here, so dont worry.

cooling is probably necessary if you are autocrossing, or running wot over and over. but if you dont do that and just go wot when you are entering the interstate, turning onto a road, passing people, etc. you really dont need cooling mods, but it doesnt hurt.
