          You better wrap that coolant hose or the turbine housing will cook it. I would put some kind of shield around the turbine housing also. Looks good and bet it sounds good to.

            Hell yeah! looks good. Its good to see another DOHC turbo out there. what are you doing for fuel/tuning? what turbo are you running? I would highly advise you to use some serious heat wrap on the fuel lines and new the wiring. i used some heat sleaves over my fuel lines and you already have the piping wrapped. I got a turbo jacket for the exhaust housing for mine for i think Titan motorsports (Toyota Supra specialy shop) and it helped a TON. Looks good tho.

              Well here is a list of specs on the car , instead of typing it all out ill just copy and paste it lol.

              1991 Pontiac Grand Prix GTP
              5 Speed Manual Transmission
              3.4L DOHC V-6 4 Cam Engine
              Heavy ported upper intake plenum
              Heavy ported lower intake
              Heavy ported heads
              Heads Machined .010"
              Intake cams advanced 6 degrees
              Exhaust cams retarded 6 degrees
              Underdrive pulley
              Billet aluminum engine strut with poly bushings
              Magnaflow high flow catalytic converter
              Flowmaster 40's series original flow mufflers
              Spec Stage 3+ race clutch
              Turbonetics 62-1 - 62mm turbo, stage 5, vband, .58 a/r
              Turbonetics Evolution Wastegate
              Turbonetics Raptor Blow off valve
              X02 Racing Intercooler
              Polished Aluminum pipe kit for intercooler piping
              Ford Racing 42.5 Lb/Hr injectors
              GM 2 Bar Map sensor
              Battery relocation to the trunk
              Autometer Phantom Boost gauge
              AEM Wideband 02 sensor
              Custom computer tuning
              17 x 9 Saleen mustang rims
              P255/40Z R17 BFGoodrich GeForce KDW tires




              So basically the turbo is a Turbonetics 62-1 stage 5 turbo ,62mm, .58a/r , v-band (this thing spools fast!)

              as for computer tuning im messing with the TGP code to get it running right, having the autoprom emulator makes this alot easier.

              and for fuel im running 42.5 Lb/Hr Ford racing injectors

              i did wrap up the fuel lines with heat wrap and i bent them up outta the way so there not so close to the downpipe , and i also wrapped the end of the master cylinder for the brakes because it was close to the downpipe at the end.

              im definatly going to look into that exhust housing wrap though, it looks like it would really lower under hood temps.

              as for speed, lets just say, it hauls ass. right now its only boosting to 7 psi, when im all done tuning ill turn it to 9psi.

              but last night me and my neighbour were emulating going down the road and we did a 0-60 test, and with a crappy launch and it running at 10.5:1 a/f under boost we pulled a 0-60 off in 5.5 seconds so when it bring the a/f ratio to about 11.5:1 and raise the boost , this thing should really haul.
