I'm in the process of buidling a 4G64 turbo. The block/crankshaft and fly wheel have been machined already. I'm waiting on the balancing to be done because I'm elimminating the balance shafts then reassembling the engine. Some parts in the build:
Manley rods/piston 8.5:1 ratio
Cometic HG/ arp head studs
Mitsu TDO6-20g
2g manifold
Punishment racing SS O2 housing 38mm ext wastegate recirculated
Tial Sport 38mm wastegate
STM -6AN FUEL RETURN KIT, FPR & GAUGE
Walboro 255
FIC 650's
Front Mount intercooler
4G64 oil pan with welded fitting for turbo oil return
Act 2100
Southbend Full kevlar face disc
Alot of misc. stuff
1G/2G turbo parts (like crushed 1G BoV)
Some stuff I prob missed
I still need the tuning stuff (the end of this month):
Egt
Wideband O2
Pocket logger
Boost gauge
Maft gen 2
J&S ultrasafeguard
Plan is to drop the engine back in at 8.5:1 (gonna suck with such crap power)bolting factory exhaust manifold, injectors, exhaust, etc. putting 500 miles on the motor (making sure the engine is in good shape after the rebuild), then bolting on the turbo stuff and begin the headache of tuning.
