Hey ware would i find valve body upgrades to buy specific for my is300 04' or do i have to send it out? plz help thanks

 

Call SRT (Swift Racing Technologies). They might be able to send you the parts so you can do it yourself. It is worth a shot.

 

Yeah, SRT might be able to help ya, there's also other kinds out there like PFS,IPT, Level 10. Not quite sure how the DIY difficulty is. But if your IS is an auto, you might want to look into the tranny cooler along with the vb upgrade, because the vb heats up the tranny alot quicker and the cooler is self explanatory (cool down the tranny, lol)

 

I bought mine on my.is for $100shipped. I paid $450 for install, ( I know expensive) but it was the only shop willing to touch my car. Plus they had 3 turbo's IS'3 that were installing.
