Following a fully forged rebuild, my Coupé will be off to see Leighton next week for a remap. After 6 years with forged pistons but standard rods, it's time to finally see what this turbo can do!
Previous spec
Hybrid GT28 (0.64 housing and custom compressor wheel)
82mm Wossner forged pistons
Balanced and shot-peened standard rods
Synapse Synchronic diverter valve
12v Fuel Pump Supply 'Wiring Mod'
FC Performance 3” 5 stud turbo-back, twin silencer exhaust system
A'PEXi Power intake
Pro Alloy 3” Straight Induction
Pro Alloy FMIC with FCP custom shortened pipe route
FC Performance 3D boost control system
Walbro GSS340 255l fuel pump
440cc fuel injectors
Big MAF
Mapped for mechanical sympathy (1.5bar, trailing off to 1.3bar at the redline) it made:
416bhp
328lbs/ft
Dyno charts attached for reference.
Changes - Now fully forged
82.5mm Wossner forged pistons (now 2022cc :D)
Maxspeeding rods
ARP 200 rod bolts
Seimens Deka 630cc injectors
