all this depends on whether its trade or retail price one thing you havent looked at is lubrication system: high volume or modified oil pump - budget round 300-500 bucks new or round 200 to modify - or source a TRD oil pump maybe cross drilling crank and journals - $150 id also go forged pistons (a little oversize maybe 20 thou) with shot peened rods as suggested - shot peening cost me 40 bucks a rod trade price (bankstown airport engineer there) so bout 900 for pistons\rings and 160 for shot peening - then get crank linished, and nitrided then get entire rotaing mass balanced and if possible blue printed, including the flywheel and pressure plate combination (individual clearances are matched up here and checked) then look at your inlet manifold - make sure at the very least it is port matched and if possible, get a custom plenum made up to suit standard runners then throttle body upgrade perhaps to compliment extra air flow required - do this in keeping with same aims as fuel system - ie . rail, lines, regulator, pump, etc verniers are a definite with aftermarket cams and turbo - if u dont want billet then get them reground for bout 150-200 each (trade once again) to suit ur planned ignition timing and power\torque curve i'd just upgrade coils and use revamped ignition system with new ecu - all good ecu's will allow you wasted spark or direct fire ignition setup, but use either good new bosch coils or get an msd blaster coil or the like. and then focus on free flowing exhaust including custom dump pipe, good front mount, piping and COOLING SYSEM - check ur water pump is working properly and maybe add another or larger fan, bigger radiator (recored or alloy) - you dont want this to cook ur newly acquired goodies. cant think of anything else for now - if i remember anything ill add it cheers [Report message to a moderator]
