I picked this boat up from Hotbo back in Aug. Motor is a 5.3 with Ls6 cam and springs, otherwise stock. Fabbed up all of the hardware, set the pump back, painted it, went through the trailer, wired and plumbed it over the winter. Rail kit, mounts, flywheel cover and transom plates were all done on a cheap KBC tools benchtop mill. Headers and hotside were tigged from bends and then coated with jethot 2000. Turbo is a Garrett m1 from a Detroit with 75mm compressor wheel (sorry GN7, no JD parts). Should have the intercooler and hat this week. Ran 70 on gps na, so I'm anxious to see what some boost will do.

Man thats a cool looking setup, one word of caution though. Those headers will glow red hot while making boost. So without a doubt you will need to heat shield them or they will melt the backs of those seats and everything else around them. And the radiant heat will travel a long ways. Just tig some 1/4" bolts to the headers for studs and build some shields that are easy to remove. Very simple. Check my build thread, its how I did it and they work great.
They will need to shield the plug wires also as they will melt in 1 trip. Ask me how I know ,lol.

Thanks for the heads up. I was hoping the jethot 2000 would kill enough of the surface temp that I would be able to get by without shields, but they get pretty hot even running it na. I will probably have to make them clamp on so I don't ruin the coating. I do have some kevlar heat sleeving for the wires, do you think that would work?

I hate to be the bearer of bad news but that coating is going to go by-by after you run it the first few times. The headers I have had been jet-hot coated with the ceramic stuff and its gone.
Its going to take something like this around that hot side.

Really? They told me the jethot 2000 would withstand surface temps over 2200 deg. Guess I'll start building some shields. Thanks for the info.
BTW, i'm a huge fan of your build.

Are those headers mild steel or stainless?

What are you using for the ignition system ?

The coil packs that mounted on the valve covers would have made a real nice setup.

Hass: They are 304ss

Mark: Using MSD 6010 with stock coils, just moved them down on the rails.

GN, with all due respect, just pretend you never saw this thread. Turn around and walk away, you probably wouldn't add anything positive. ;)

Excellent, I looked up that ignition box. I couldn't find specifics if it gives all the coils a minimum charge time of 5ms which would require charging 3 coils at the same time or just divides the charge time by the crank revolulution in which case it would get shorter as the rpm gets higher.

Those steel sleeves the stock plug boots come with should give some heat protection.

Running a berk B with an DPS inducer @ 5000. There is a little left in the motor with jetting and timing changes. No vids yet
