well i've done a search about the sms throttle body thats about 3mm bigger and smoother than the stock lsj, helping out with just throttle response, but it wasnt really clear to me if this was stock or not. i figure it's a supporting mod, and will help out with other mods, but can I (capitalized) benefit from this with my mods (listed in sig)?

also anyone have a stock 2.0l sj one for sale(unlikely)?
