Hi Everyone my name is Steven and i'm new to this forum. My dad is the owner of a 2003 Mini Cooper S JCW. He is not a forum guy, So I told him I would register for him so he can get info on his Mini. Im part of SRTForums and a local forum called LVSRT in Las Vegas and I was telling my dad that the best advise is to go to a mini forum. We have been into tunning cars for a long time a few are 300zxTT, NSRT-4, 300c Srt-8, Mazdaspeed 3, and some classic's. So My Pops would like to get more performance out of his JCW and thats what we are here for. We know that his car has upgraded injectors and JCW cai "we think" this car is still kinda of forgein to us.lol So any advise would be great. Plans are first to get sprint booster and to get a proper intake or upgrade the filter in the JCW intake it has. Thanks again looking forward to meeting Mini people.

 

Welcome, let the fun begin

Welcome! Wanting a little more performance, that's where it starts...

If you've already got the JCW 380cc injectors and JCW intake, most would suggest you upgrade to a 15, 16, or 17% pulley kit. Depending on how long the filters been in there, changing it out couldn't hurt, but it is actually a great intake!

Good luck!

 

Now I thought the JCW came with a 15% pully already on it. I do need a new filter I pulled the old one out not only was it dirty but it was a paper one. I think I will go with the maddness filter(I think thats what it's called)I also opened the flap and reset the PCM and it gave the car some life!
