It seems like I added everything up and it was about $1200-$1500.

Rough estimate of my parts list
-Offy intake = $150
-Holley 500cfm 2bbl = $150 after rebuild
-GT35/T4 Turbo = $300
-Wastegate = $60
-B.O.V. = $60
-292 Manifold = $100
-Turbo oil feed/drain kit = $50
-Mandrel bends and piping and flanges = $150
-Intake tubing, bends, and couplers = $80
-Spectre Turbo Hat = $100
-HEI = $100
Plus various parts which puts me right at $1300+

I think turbos are better for fun daily-drivers and supers for drag cars and show cars. Because even though I haven't driven a supercharged car first hand, it seems like mileage would be terrible since you can't control the boost with the throttle plate position. I'd rather have a little turbo lag and be able to drive it everywhere. I mean I got 15psi by 2800rpm so it's not that bad. And that 15psi was badasssssssssssss. But 3psi like I running now just makes it a little more torquey. I'm going to probably keep it at 6-8psi after a spring change. I'll stop rambling now :-)


69 Buick Special Deluxe. Intercooled Turbo Chevy 250 @ 15psi on a stock long block. It's kinda fast.
