after running the twin turbo set up on the stock motor with very good results , it was time to upgrade my spare motor and start running lots more boost
custom m2/je 9.5.1 pistons
300 hp wrist pins
custom titanium connecting rods
custom head studs and mains
hd valve springs with titanium retainers,ported and polish cylinder heads 13% more flow
fully balanced engine assembly
and so much more
engine can rev to 9500 plus rpm now
30 psi plus boost pressure on the twin efr 71/63s
PLEASE KEEP THIS THREAD CLEAN !!!THANK YOU

vbox 60 to 130 mph run ,stock motor 13 psi of boost with bad shifting and some wheel spin
1/4 mile but way to much wheel spin till third gear but some decent trap speed!!!

Nice,
A few things I'd have done different but makes a nice change to see someone actually modify one of these rather than just bolt some crap on it lol
Guessing at mid 600's so far !!

At least you got rid of the boot spoiler... You did get rid of the boot spoiler didn't you?
