This is one BAD ASS STi engine by IAG ! If you are im the market for a STOUT long block that can handle some serious boost and high revs , look no further. The STG 4 tuff features the “1150 “ style ultra strong closed deck system ! The bottom end has IAG spec 99.75 forged pistons , IAG tri beam + 2 mm rods , that’s right shes stroked and bored. ARP rod bolts and king bearings make it spin smooth. The heads are the almighty STAGE 5 heads by held down by 14 MM arp/ iag spec head studs and they are FIRE LOCKED to keep all the boost juice inside. You are able to run INSANE 45 psi of fun with this set up ! The fully built heads are port and polished and have GSC cams and running gear ! At this price you can over build your set up to run 750 hp or be a man and hit that shrimp to make 900 ponies. This block falls between a 950 and 1150 block ! Amazing strength and tough as NAILS !
