I might do some mods which would lead to me having over 200 horses but with the stock head. I noticed the JCW swaps out the head. Should I be concerned with the long term effects? Do you think its definately worth a change?

Who here has mods and lots of miles with no issues?

 

bizump..

 

Since I got no help I did my own research for a while and found out that its definately not required and will have no affects.

 

Patience dude. Sunday night is not exactly peak usage time for this board.
I think that it's generally accepted that the stock head on an MCS should have no issues with 200 to 220hp.

 

requirements for 200hp (my opinions on product in paranthesis):
Cold Air Intake (Alta with silicone tube)
Pulley (Alta, your choice on size, 19% if you want the three extra power but you don't wanna run to redline)
Exhaust (Milltek, Borla Race, Magnaflow, make sure to check out the exhaust reference thread, not too big a difference in numbers but BIG difference in sound between these three)
ECU (Unichip)
that should do it, if not you can do the head and a Cam. and don't forget about suspension and the rest of the car along the way.

again these products are just my opinion, please no flames about manufacturer's

 

Well, we will find out everything exactly. I'm getting a dyno done when I head out there.
