need info on exhaust stud pattern fs v bp

hi guy/gurls i'm interested in this thumper kit that is currently available from MAM, but since i have a gtr familia (awd with turbo already)which has the first gen bp engine and have done a second gen head conversion (has had heavy porting and over size valves ), i need to know if the exhaust bolt stud pattern is the same as the FS engine , if so i can upgrade the current RHF6/VJ23 that is currently on it to something a bit more user freindly (see really large laggy turbo with all or nothing) and i am not going to get antilag any time soon (well maybe one day) anyway post me with some info. (help)

Well if you did a 2nd gen head conversion, and you are still using the GTR turbo and manifold, than I would say that the thumper kit which is for the FS??(i dont know much about the p5 and MSP motors) will not work. Different motors. Why do you want to get rid of your GTR? Those things have been known to put down 300+ hp. You would be stupid to let that turbo go.

well i am not getting rid of the gtr just updating the engine ect for the new millenium and i already have close to 300 , but with the on/off nature of the car it has a bad habit of snapping me sideways with the sudden pwr surges and trying to do race work round a circuit makes it a really b*tch to drive in the correct rpm range which to keep it going nice has to be round 5-6500rpm minimum , the turbo is damn tough with me blowing a piston and feeding it through the turbo at a drag meet and it still goes , now the head conversion is a month away till i get it back from the head works were its getting bigger valves , better springs , ect ect, and hopefully a new set of cams with a matching pwr curve for the turbo (thinking garret 3071) with the new thumper kit if i can find out if it fits the second gen head for the 1.8 , thus the question since they say they only make em for FS engines.
