Slant six turbo cost analysis: 300 hp
This will attempt to determine the actual cost of building a (nominal) 300 hp slant six with a blow-thru carbureted, turbocharged 225 engine that will feature stock-type (cast aluminum) pistons and stock 225 rods It will be limited to 10 pounds of boost, without a chemical intercooler, and 12 pounds, with a water/alky injector.
Let the games begin....:happy1:
All contibutions/ideas will be appreciated!!!
Time to get started with this "el cheapo," slightly more reasonabally-priced version of the forced induction slant six, 225 variety:
Block, crank, pistons and rods will all be free, because they likely will be. The machine work to "freshen-up' what needs attention, probably won't run more than $500.00, and would include turning the crank .010"/'010:, honing the cylinders, and installing new 1.75"/1.5" valves in the un-ported head.
A set of rings should run no more than $212.00.
Rod and main bearings will be about $50.00, with a new Fel Pro head gasket for $17.00
A new timing chain and sprockets will run about $38.00...
A Super Six 2bbl intake will likely be $150.00.
A Holley 2bbl 2300-series carb in the 500cfm size will be whatever you can find one for; probably, $250.00...
Blow-thru mods might run $500.00, or a LOT less, if you are capable of doing them, yourself.
Stock rockers, pushrods, a new set of solid, flat tappet lifters will be about $60.00.
Valve springs will run (340's) about $90.00 (ebay.) Maybe less, elsewhere...
Time is over for this session; more later...
Subtotal, so far: $1,967.00
As always, feel free to add comments, facts, opinions, etc... all are welcomed, here...
