U. R. under drive pulley

Hey, I was just wondering if anyone has installed an unorthodox racing underdrive pulley. I just wanna know if its worth the time and money. And if its fairly easy to do. There doesn't seem to be much room to work. There is a performance engine rebuild kit for our cars at: http://importperformanceparts.net/ $929 On ebay there's a cold air intake for the MX6 that looks like it would be a pretty good fit for our car. For about $50. There are some cheaper ones but think that one is your best bet. Also on Ebay I've recently seen some OBX headers that said they would fit the Millenia. I don't know if they are still listed. But I'm pretty confident that the ones by SSAutoChrome will fit. they usually sell for about $150-$300. Alot of the Probe Gt guys have been using an MX3 flywheel with some good results. Anyways there's a ton more I'm sure most people already know about Corksport and The Thomas Knight superchargerkits for 2.5L. An theres always the old stand by NOS. Nitrous Express makes a real good universal import kit. That you could run about 35 shot. Which should be fairly safe. Well anyways I'm sorry this was so long. But I hope it might help some people. But ya any info on the U.R. pulley performance would be appreciated. I'm still learning myself. So if there's any other info on what we can do with these cars. Please share

Forget about that part about the MX3 flywheel. I just re read my message and relized I was way to tired when I wrote it.
