ive seen several guys running the hahn stage 5 on a 420a, and theyre building high 300/low400 whp...
and i dont trust those streetfire videos...next time i take the old dodge to the track ill take a video of a mid/low 12 second run (dont actually know yet) and then i post it on streetfire as "1983 mirada, stock bottom end, intake, gears, catback..sick"...

 

FIRST OFF I THINK THE SPYDER IS A SEXY CAR AND A DECENT CAR BUT JUST NOT A PREFORMANCE MACHINE . SO I AM NOT DISING IT . ALSO ITS JUST NOT A SIMPLE SWAP TO PUT THE STOCK 4G63T DRIVELINE IN THAT CAR GS/RS THE MOTER SITS IN THE TOTALY OPISET THE MOTOR MOUNTS ON THE UNIBODY ARE IN TOTALY DIFFERNT LOCATION ANY EXPERINCED DSM TUNNER WILL TELL U ITS A WASTE OF TIME AND MONEY IT IS CHEAPER TO JUST BUT A TURBO CAR AND YES YOU CAN MAKE 5-600 HP SAFELY ON A STOCK 4G63T MOTOR.
IN MY OPION IT IS A WASTE TO SPEND ALOT OF MONEY ON THE 420 ANYWAY BECAUSE U ARE NEVER GOING TO BE ALL THAT QUICK ANYWAY YOU ARE GOING TO GET A LOT MORE BANK FOR BUCK WITH THE 4G63T
ALSO IF U HAVE HAD A GS OR RS UP TO 145 IT WAS A VERRY STRONG MOTOR I HAVE OWEND 3 OF THOES CARS AND THE BEST TOP SPEED WAS 133 MPH AFTER ABOUT 4-5MI THE OTHER 2 WHERE 132 AND 129MPH AND IT ALWAYS TOOK A LONG TIME TO GET THERE LIKE SEVERAL MILES.ALSO THAT WAS WITH NO SPEED LIMETER OR FUEL CUTT KICKING IN SO I AM NOT SHURE IF THEY HAVE ONE I HAVE A THINK ABOUT GETTING THE TOP SPEED OUT OF ALL THE CARS I DRIVE LOL
