Where the engine is at now,
-A12, Standard pistons, cast rings, standard rods, H89 head(standard)Arp head studs.
-EFI
-236 Deg at .050(Edited from 256 deg, made a mistake)
-600cc seimens injectors
-E85
-Stock Turbo off twin turbo Skyline ($100 secondhand)
-11psi Boost
Im limited to about 14Psi with this turbo because they are made with a ceramic turbine impeller. Much more boost than this, these turbines tend to fly apart.
Here is the dyno grph of where its at at the above specs:
I`ll be fitting a steel turbine wheel to this turbo next. The upgade steel turbine and rebuilt kit is about $380. I`ll post another graph when this is done.
