yea, keep the VG, the SR is a great motor don't get me wrong, but for that chassis, that engine can make so much power off of minimal mods and some decent tuning. I'd PM Mattback if u wanna make 400 horses and save an ass-load of cash-o-lah (by not buying the SR)! Goodluck bro if u ever need an extra set of hands or the right tool for the job, PM me.
