Replace rear main seal Get a short throw shifter Replace the Driveshaft Get Down Pipes for sure Get a lighten flywheel Put Redline trans and differential Oil..As far as Turbo's do it two stages unless you want to spend another 10K-15K in just the engine alone. The engine is good for 500RWHP then you are beyond the engine limits. A set of Super T28s or HKS 2530s or JWT600s or something similar will do you good. After that you need to goto something like TD05 kit or something even larger and that is beyond what your engine can handle. If you build your engine you are going to do the following 1) New Rods 2) New Pistons 3) New Valves 4) New Valve Springs 5) New Valve Guides 6) New Lifters (unless you want x-ray your current ones) 7) New injectors (as 555 will get maxed out) 8) Upgraded Throttle Bodies 9) Reworked Crank 10) New Rod Bearings 11) New Piston Rings 12) 5 Angle job and other headwork 13) Ported and Polished upper and lower plenum 14) New Stud Bolts 15) Balancing, blueprinting, mangnafluxing, powdercoating, cermaic coating, and etc. And since the engine is out might as well replace the steering rack bushings.. Either way after you upgrade your engine you will want to replace your brakes with a bigger brake kit.. Also according to the results nationwide if you have more than 350RWHP you are in the top 5% of all the cars dyno'd in the US.
