Hey I've seen your post a few times and never got the chance to respond. I'm from T&T ( Trinidad and Tobago ) and a buddy of mine also has an original 4WD Bluebird SSS. He swapped in an Aviner engine and upgraded with some bolt on parts ( Stock ECU, SAFCII, T3/T4 Garrett turbo, Ebay RWD tubular manfiold, 300ZX airflow, 38mm tial waste gate and upgraded injectors )The car did 400whp ( stock internals ) on a dynojet down here and did a best time of 11.7 consistently with full interior on the 1/4 mile. The car did 500whp following internal upgrades ( forged rods, Pistons, ARP head bolts, ARP rod bolts and Cormetic Headgasket ). Everything else remained the same from his 400whp setup bolt on parts. Presently everything was scrapped out and now the vehicle is up for sale as he is putting his SSS setup in a 4WD B13 drag car.
Here are a few dyo vids of the car
