Slant Six Turbo cost analysis

I want to do an accurate-as-can-be cost analysis as to how much capital is necessary to spend on creating a turbocharged slant six engine in two states of tune; a 300 horsepower, and a 500 horsepower version.

They will both be carbureted, and both utilize as many stock, original components as is practical, to keep costs down.

The 500 hp engine will utilize forged pistons, rods, and be intercooled. The 300 hp version will have stock (cast) pistons, stock rods, and use no intercooler.


I will set up two threads: one for each engine. I don't have unlimited time to give to this project, but I don't think it will take very long to arrive at a number for each finished engine.


I will be soliciting the help of anyone who would like to assist in this endeavor; It's a big job for one guy...

Please feel free to add whatever info you have; it will be more than welcome!

I am guessing, (wild guess off the top of my head,) $4,000.00 for the 300 hp motor and $7,000.00 for the 500 hp version.

We'll see how close I come... :prayer::prayer::prayer:
