Slant six turbo 500 hp cost analysis
now im not anywhere near 500hp yet but i built my setup to hold it in the future so i dont have to buy stuff twice. i also found some things much cheaper then you have listed.
distributor can be had in a junkyard for around $20, check it for play, if its good then you are good to go. you could probably get a lean burn distributor for the cost of shipping if you ask around.
650dp holley, $50 + $45 for a rebuild kit and $12 for the nytrophyle (sp) floats. the hangar mods are free they just take a little time.
ebay 31x11x3.5 bar & plate front mount intercooler $98 should be good 500+hp.
the exhaust header can be made from old headers. ive picked up a couple sets so far just to make one of these and im $20 into it so far add the ebay flanges and the turbo flange and it comes to just about $60
the offy 4bbl intake can be had for $100 if you shop around and are not in a hurry but go for $150 regularly.
Junior.
I deliberately set the prices on the high side for two reasons; 1. not everybody has the ability to find and buy used equipment and make it "right" if it is worn or, otherwise not quite "operational..." (You, obviously do,) and, new stuff always costs more. 2. I am not very well-versed in the cost of putting together the "right" combination of parts (such as intercoolers, turbos and such,) and would rather err on the high side than the low side, so that someone with budget that is dependent on my figures here, doesn't come up with not enough money to finish this.
I forgot to add any money for a blow-off valve or a waste gate controller... probably $200 to $250-worth of stuff, and a carb hat.... another $100.00, or so, if you buy the cheap one.
Using your modus operandus, it might be possible to build a bonafide 500hp turbo slant six for as little as $7,000.00, but I think it would be tough.
But, think about the advantages of the leaning tower of power, vs. using a 360, for example: You (with the 500hp slant six) have an engine that has a slow, smooth idle, lots of low-end torque, great driveability, good gas mileage, has no requirement for an expensive 8.75" rear end and TWO sets of gears, (a 4.88 for the strip and a 2.76 for the hiway.... the 2.76 seems to work perfectly for both in the slant car.) That gear will KILL a built 360 on the drag strip.
The stock drive shaft will probably fit and work perfectly, where a 360 would probably need a new one built.
I have not addressed fuel delivery problems (yet) because this thread is JUST about the engine; fuel pumps and cells are more of a chassis issue, I think.
There may well be serious omissions on this list, but at the moment I can't think of any...
ANYBODY, please?
