Of course, sitting here typing, I'm not getting my Supra back together, but I'd give it a try.
Don't think it will break 600, but I'd be pleased if it did.
Mods:
Stroker 7MGTE, total displacement is about 3.24L.
Ross Pistons, Pauter Rods, ARP studs for head and crank, custom oil setup with accusump and RX7 cooler.
Rebuilt R154 with new second gears etc.
Everything is coated.
780 Delphi injectors. Two 255lph pumps, Areomotive AFPR.
Maft Pro and PLX wideband.
Masterpower T70 on modified Ebay manifold into 3" exhaust.
14" brakes front and rear with 6 piston and 4 piston wilwood calipers.
TEMS tokikio's with B&G springs. ST bars.
It's setup more as a road race car than a dyno mobile or drag racer, so I'm not sure what the ultimate power of this setup will be.
I also need to get it done, and do some tuneing to get it right before Vegas... (Running out of time now, and really my wife does not want to go this year, and it's right over her birthday... Let's see, dog house and the couch and go to Vegas, or stay home... LOL)
