Phase 1 - purchase in 2009 as a 20vt 4K, 2-piece conversion suspension with big springs and Bilstein HD's - otherwise stock
Phase 2 - 20VT, new wiring, JVAB 50mm Bilstein, Porchse 944 intercooler, V8 oil cooler, k24 (3), GT2871 (2), GTX2860(1)
-- Blew 3 K24's
-- Melted a motor, rod knock
-- Found a 20yr old crate motor from EFI Express (thanks Marc)
-- Due to an unfortunate blockage in the oil restrictor for the turbo - blew GT2871 #1
-- After Dyno on a new GT2871, decided we needed to go to a smaller turbo - so GT2871 is now in a box
Phase 3:
Why would I need a phase 3?
-- Blew the turbo in October at Charlevox - seems there was a boost hose disconnected, turbo was overspinning, moment of cavitation, turbo bearings and cage explode and regurgitate into the oil pan, pickup sucks debris into oil pump, seizes oil pump, toasts engine. Oh, and just before Charlevoice - the night before, found a cracked EM with bits missing (replaced in time for rally) - who knows how that participated in the demise of both turbo and motor?
Plan:
-- Motor rebuild (thank you Randall at Precision Balancing)
+ Weisco Forged Pistons 0.20 over
+ JE Rods
+ Coated Bearings
+ New Oil Pump
+ New Squirters
+ rotating assembly balanced
+ Valve Job and light deck
-- Refurbish Radiator
-- Make calculations to determine what the best turbo is, given the 32mm restrictor
+ New restrictor with proper design
-- Accusump
-- New Oil Cooler
-- New EM (Wagner cast or IROZ tubular)
-- New DP is most likely required
-- Dump valve rather than recirc (gives more flexibility for piping and expected length of new restrictor)
Goal:
-- Reliability
-- Maximize Boost as early as possible
-- Moah torque!
-- Try to maintain theoretical max of 250 or so hp
-- Can we get close to 400 ft/lb of torque and remain reliable on pump gas?
