    The only difference I had in mind was to have the turbo mounting flange facing forward like the one in this picture, instead of facing upward. That was because I hadn't thought it out thoroughly. I like your setup better.

    We have the narrow engine compartment, too ('64 Valiant.)

    The only advanatge I can see with my idea is that the tubing would only have to "bend" 90 degrees instead of 180, but that's probably totally unimportant.

    Here are a couple of pictures of the way I had envisioned it to face (simply because that's what WE had.)

    I had nothing to do with the construction of that piece of tubing; didn't even know it was being cut and welded up.

    PISHTA thought it up and made it happen. Maybe HE has some pictures taken during its construction...

    There may actually be some sort of advantage (space considerations?) to having the turbo mounting flange facing forward like our headers, but I am surely not saying there is; I just would investigate it before I built anything.

    Possibly, you could offer both setups at the same price, since they would be so similar. Then people could take their choice...

    Either way. I don't think it's going to be very complicated to make.

    One consideration, however, that hasn't been addressed, would be to cut about a 1.5"-hole in the U-Bend and weld on a mounting flange for a waste gate. That shouldn't be much of a problem. Get some feedback from potential users as to what position they'd want it in (clearance issues.)

    I hope you're able to do this; I want one....:cheers:

    I'd have to find an early A guy for clearance concerns, I have a 71 Dart that I could use for mocking things up

    The engine compartment is wider beginning in '67, as you know, but I THINK that's pretty much the only difference. You could measure from the block to the inner fender panel to get the difference, if you had accesss to a pre-67 A body. Shouldn't be a problem to find one, or I could measure ours (1964 Valiant.) Let me know if you need me to do that. I'll help however I can; I want to see you get this done (for selfish reasons.)

    with you guys doing or planning on turbo slants, how would you feel about a four bolt main setup? I'm excited to start working on stuff for this. I still need to hunt down a slant and k member for the dart. I think it'd be cool to make enough parts for the Slant so that guys could have them running with the super stock Darts on the track ( i know that makes me sound stoned but i think it'd be possible)

    Rather than a 4-bolt setup, I think this (pictured) setup might be even stronger and cheaper/easier to build. I don't know where this picture came from, or who did the machine work, but it looks eminently do-able to me.

    Looks like they just machined off the top edge of the original main caps and added some bar stock to the machined surface, for added stiffness.

    I'm still waiting for your U-Bend turbo mounting flange that would make it possible to mount the turbo slose to the stock exhaust manifold with no welding on the cast piece.

    What's up with that???:-|

    That picture came from here: http://koti.mbnet.fi/trc/technic.htm And that engine made 564 rwhp.
    I have done this main cap mod to several VW diesels myself, since these tends to crack main caps. This 1.6 turbodiesel made a little over 200whp, before it threw piston pin out :lol:
    Just mill main caps flat and make steel bar on top.

    waiting to graduate high school Bill, got a few more weeks and I'm out. After that I'm going to put some money towards equipment. Also still trying to get a slant to use as a test rat

    Kudos to YOU for hangin' in there and graduating!!!:cheers:

    THAT is critically important; this is just a hobby...

    Concentrate on your schoolwork; there's be plenty of time for this stuff later on...

    First things first....

    Well, that sounds like FUN!

    Hang in there, and don't let anything deter you; you don't want to end up like me; 5 different colleges and no degree...:banghead:

    lol, that wouldn't be fun. I have the opportunity to pick up a slant 727, what would you guys think of a recast housing?

    The 727 transmission is a heavy duty unit (emphasis on "HEAVY") that is at home behind a 440 wedge or 426 Hemi. It has the capability of handling 600-700 HP without a lot of failures, but behind a slant 6, it's just excess baggage, in my opinion. The unnecessary rotating weight that must be spun up, will slow a slant 6 car down at LEAST .15-sec in the quarter mile, maybe more, compared with a 904... which can be built to handle 600+hp...

    I can't see why anyone would want to use one behind a slant 6. Even the turbo motors (and my own supercharged 360 Magnum) work well with a 904. I think they put them (727's) in slant 6 trucks and taxicabs.

    If performance with a slant 6 is your goal, the 727 is not the way to go; too much parasitic drag.

    My 2-cents...

    i knew about the big blocks getting the 727, i didn't realize how stout you could build a 904 i guess

    There's an aftermarket transmission company called "Pro Trans" in California. They build a LOT of transmissions for NHRA drag racers in a variety of classes. Most of their competition transmissions are modified 904's, but I think they install 904 (or custom-built 904-spec) parts in 727 cases in instances where a 904 won't bolt up. There are a lot of mid-8 second 1968 426 Hemi Super Stockers (900+hp) running these transmissions. I have a good friend who builds racing Torqueflites for a living, and has for 30 years. He told me that a 727 is its own worst enemy, because what usually causes them to fail is not the torque going through them, but the inertia of the heavy internal 727 components starting and stopping from high rpm. They literally tear themselves apart, just going through the gears. His name is Len Schneider, and he has a shop in Grass Valley, CA.

    He built the converter in the Dan Fletcher-driven A/EA that just won Comp Eliminator at the Las Vegas NHRA national event, this past Sunday. I believe that's the 2nd national event win for car owner Rick Braun, already this year; it's a former world-champion race car and is really hard to beat in NHRA's Comp Eliminator.

    When he (Len) talks, I listen...

    I think performance parts for the slant should begin at a basic level, just like anything else. While we can dream all day about turbos, blowers, crossflow heads and the like, those are some very expensive projects.

    I say start with something that you actually have a chance of doing. For instance, try contacting piston companies and see what it would take to get a piston made for the slant with a better compression height. Something that would use the stock rod, instead of having to spend 500 for a set of K1s or somebody's ridiculously inflated price for a set of used 198 rods.

    Also, no one makes thin head gaskets for the slant anymore. If a gasket company saw a segment of hobbiests ready to buy a product, they might just make it.

    And what's so special about a set of Hooker headers that makes them over 500 bucks? Somebody out there can surely beat that price.

    No off the shelf cam grinds are available....unless you want your slant to idle stock and have a really small increase in power and if that's your game, then go with Comp. Ghey.

    A lot of areas need work by simply trying to lobby manufacturers into making the products we want. It's up to us to stand up as a group READY with our dollars instead of our mouths.
