Replaced my rattley VCT with camgears... and discovered that it had been masking a somewhat more serious rattle... spun bottom end bearing possibly caused by oil starvation. So engine is out and fully disassembled, from first inspection doesn't look terminal... crank can probably be reground. A wise man told me to look at this as an oppurtunity... so I'm looking to do some upgrades.
This is my daily driver, so I want reliable usable power on the street... aim is 300kw on E85 with maximum response. I feel the 3071 is too laggy in the current setup / goals.
Current Build: GTX3071 T25 IWG (low mount, single scroll, 0.64 A/R), Plazmaman plenum, FMIC, TOG ex. manifold, 3" Exhaust, Wisco Pistons, Manley Rods, Solid Lifter Conversion, Tomei 260/260 cams, Bosch 1650cc EV14, Haltech Platinum Pro, etc
Ideas:
a) Stroker Kit - Use 91mm stroke to improve low rpm tq and bring current turbo on boost earlier
b) Change Turbo - Move to high mount with twinscroll EFR turbo (probably 6758)
c) VET Head - Convert to SR20VE VVL head
d) Others - Port and Polish, Valve Job, Crank Balancing, etc
Anyway just want to get an opinion on what will give me the best bang for the buck / least hassle. I've got access to a decent workshop, so I can do most labour / assembly on my own.
