i have a tdo5 14b with braided oil feed line and dump pipe. can also throw in a slightly ported exhaust manifold. this setup just scrapped me into the 12's Consistant low 13's and has more in it with a better porting job. $350
you will only have to get your exaust flange rotated a little to get it to fit. all the rest of your gsr turbo stuff will bolt up to it.
