Hey Rusty,

I've seen those. Goofy, but pretty impressive! lol

The good ol H1C is a great turbo. The one on my cummins is putting out 25psi plus at full tilt with a slightly modified injection pump and a heavy foot. Takes a little while to spool, so be aware of that. it'll probably be worse on the slant. But overall a pretty bulletproof turbo. the turbo stalls a lot from my dumbass snapping the "throttle" shut and it hasn't ripped apart yet.

You’d be surprised. If it’s on there and torqued down you might as well use it. When it eats coolant, pull the head and have a cometic made for it.

It won't, it'll push out into the cam-side of the block & smoke it, same way SB's do, & Dulcich's did......which is a good bad-thing, at least it shouldn't fill & lock a slug..
Even with port EFI & an ECM controlled timing curve, Mopar drew the line @7p.s.i. stock w/o an intercooler, & used a knock sensor because folks would use less octane than required to use the 'ideal' boost/timing built in. I have the HP Controller/logic module that will run @11psi, & the upgraded cam for the TurboI, but haven't tried them out on anything yet.....We have 94 available here,..I would be sneaking-up on the base timing watching for a peep out of the knock sensor.

I've had two blown slant six head gaskets - one leaked coolant into the cylinders and one leaked into the oil.

What kind of pressures did you blow them at Mat? And I can’t remember are you intercooled?

 

[MadScientistMat]

First was naturally aspirated. Second hadn't run more than 5 psi but had left a bottle of coolant flush in there for what was probably too long.

 

[RustyRatRod]

Yes. But buy em from Viren at VS racing. His prices are hands down the best. You can get stuff pretty cheap on eBay and Amazon but you gotta be careful of very cheap Chinese junk. It’ll cost you an engine.


VSR 44mm Wastegate Gen2

Bringin this back to the top, as I'm gettin ready to get the J pipe made and mock the turbo up. So is this the actual size waste gate you'd recommend?

 

[RustyRatRod]

Next we can get in to the ignition system. Oh it’s fun spending your money.

My plan there is not to skimp. I think I may going to go with...wait for the shock...an MSD boost retard box.

A 44 is probably too big for ~300hp slant but it leaves room to grow and there is no downside really. You can have less than perfect placement of the gate and still have good control. Also I’m not sure VS has a smaller gate than that Ive never looked.

I run the MSD 6BTM on my boat. Works fantastic. But I’d recommend the digital programmable box MSD 6AL-2. It’s more compact, has WAY more features and gives you ability to create a 3D map in MSDs software. It’s a better solution for a street car.

I'm running a Tialsport gate; I think it's a 40 mm.

Agree, the BTM is tedious to fine tune, easier with lower boost#'s..but tough when the boost gets rowdy..
