    Slant 6 Turbo... Tight quarters. I could use some pointers

    I agree than a rear-mount turbo is the only choice that makes any sense in this particular application. It will free-up a lot of room under the hood, and run a WHOLE lot better than it does, now!

    Blow through with vacuum secondary Holley Carb.

    I have a blow-thru setup running 15 pounds of boost on my 225 slant six. When I was gathering parts for my project, I was told repeately, everywhere I searched, "Get a mechanically-operated secondary carb, not a vacuum-operated one." Everywhere. I never knew why, but when I asked people who...

    turbo 6 bangers post here

    I know it's a lot of trouble, but if you are REALLY interested in trying to get over 2 HP per cubic inch out of a slant six, I would think that you ust would HAVE to build a dedicated header and not try to use the stock exhaust manifold at all. My header is just my own interpretation of...

    Will, that cam sounds pretty "lopey" at idle, for a turbo grind. How much duration does it have at .050"? Inquiring minds want to know... :coffee2:

    That stuff all looks REALLY GOOD, David! I am always pleasantly-amazed at the great quality of your work! And, I am sure those ARP studs will be fine; they are so much better than the OEM stuff... I can't wait to see this thing run!!!!!!!! It's gonna be awesome!:blob:

    You probably could find out by calling ARP; don't bother with Summit... I don't think they even know... It probably doesn't matter, anyway.... but, if it were going into MY engine, I'd like to know.

    The ARP studs in my engine are studs that were bought as a"group-buy" a few years back. The "off-the-shelf" ARP studs from ARP for the slant six are, for sure, an upgrade over the stock, OEM head bolts, but the ARP "off-the-shelf" items are machined from 180,000 psi stock. The "special order...

    When I built thid emgine... What I did (since I was inexperienced and totally ignorant of turbos and slant sixes), was to ( as closely as I could,) build a bald-faced copy of Tom Wolfe's and Ryan Peterson's engines. None of this is my idea; I just wanted something that worked, and their...

    70 dart swinger slant turbo build and mild restoration

    The '74 is a car that had gained weight through guard beams in the doors, and heavier bumpers and bumper braces, with probably other, heavier construction, but, you'll probably get rid of all that excess weight as you go through it and lighten everything as much as you can. The B-body 8.75"...

    I may be; I have no hard performance numbers to go by.... What I was using as a tool for estimating potential power-output for this J-Pipe, was the two engines that have been proven to make virtually 500 horsepower, with a pretty well-designed, tubing header similar to mine. The difference...

    70 dart swinger slant turbo build and mild restoration

    I don't know how many PISHTA pipes there is a market for, but the problem will be getting the word out that they are available, and at a reasonable price. The header that went on my car (see pic,) was done as cheaply as possible, but by the time it was tack-welded, and then, T.I.G.-welded, and...

    70 dart swinger slant turbo build and mild restoration

    My ignition system is a stock, Mopar electronic "Lean Burn" distributor, hooked to an MSD 6-AL II digital box and it works exceedingly well. It starts right up, usually on the first "crank," and has never EVER misfired. The car runs about 12-flat on 15 pounds of boost, so, I know the ignition...

    You are seriously dating yourself when you talk about the Jetsons. That cartoon came out in 1962... I was 24 years old in 1962, but I'd bet that at least 80% of the posters on this "discussion group" weren't even BORN in 1962! That was 53 years ago... LOL! ~I~ well-remember the Jetsons'...

    Thanks, PISHTA! :blob: However.... As the song says, "But, you don't know me..." I'd dump this $1,000.00, ceramic-coated "work of art" in a heartbeat, if it were proven to me that somehing else, say, a PISHTA PIPE worked better. I am "into" performance... not cosmetics. 'Nuf sed....

    70 dart swinger slant turbo build and mild restoration

    The clearances between the intake and exhaust pipes on my two "manifolds" are so close, there's just no room for a thickness of wrapping material in most locations, so, unless I change the hardware significantly, I am pretty much stuck with what I've got. I WOULD change this to a different...

    70 dart swinger slant turbo build and mild restoration

    Are you suggesting that a PISHTA PIPE might actually sap less energy from the exhaust than a conventional header; enough to more than make up for its comparative flow restrictions? That's an interesting theory; I wonder how it could be proved? I'd change my car over to a PISHTA PIPE in a NY...

    I just wish that SOMEBODY who can weld mild steel tubing to cast iron, would, at least, build a J-pipe to bolt the stock exhaust manifold up to the turbocharger, like PISHTA designed. That would never flow as well as a real "header" but should be good up to around 350 horsepower. That's...

    Well, you have made a good decision, I think. If there is anything in the way of information you need, this is a really good place to ask! It's gratifying to hear that you're still "on course." :cheers: Good luck!

    David, I'm glad to learn that you're finally getting paid for the work you did on that remodeling job. It's very depressing to make the considerable effort to do something like that and not get paid. One of life's little lessons, learned... (If possible, next time, get the money "up-front.)...

    300 hp slant w/turbo... suggestion

    Having been down that same road (I'd had NO experience with either a turbocharger, OR a slant six, before, ) I had to start at "ground zero," as far as learning what was what, so, I've "been there." There is lots of help available on this forum, and if you need more information, just send me...

    70 dart swinger slant turbo build and mild restoration

    Since you are going to buy a car to build anyway, you might consider the fact that Valiants and Darts gained weight, consistently, almost every year, as time went by. Slant sixes are particularly affected by this situation because their displacement is initially so small. I have a book that...
