Let's get this slant turbo project started. 71 Dart
I was doing a 5.7 swap, but the seller took the money and never shipped. I just got a refund and looked around and I think I have a good start for a 225 turbo project.
I want to do "The Pishta"! :cheers:
I just got the 2.5" 4 degree U pipe from Summit last night.
I have been poring over the the Forced induction section this last week and will keep reading it from oldest to newest until I have at least skimmed all of them.
Have been looking at carb hats, looking at 2300 holley carbs.
Could really use some help on what size or particular model Turbo to use :prayer:.
Any turbo sites, advice on models, or great prices out there?
Thanks FABO !
I applaud your decision to go with the turbo slant six over the small block swap. I don't think you'll regret it! Also, your decision to use the "Pishta" pipe; a great decision!!!
You are off to a great start with the attitude you have and the progress you have made so far. This will not be quick nor easy, but will pay giant dividends once it's operational.
I read your intentions and see no reason why your game plan, as presented here, won't work, with just a couple of modifications.
You asked for input, and this is an excellent forum for information, with lots of experienced slant six posters who are willing to help and to share their expertise.
My own experience is as a relative newbie, so take what I say with that in mind; I am no expert, and have learned what I know about all this mainly from reading the notes on this and other bulletin boards over the last four or five years, Our own project car (see avatar) is a turbo 225 and has yet to see the drag strip, but is ready for some test and tune sessions when the weather permits.
My opinion (and, bear in mind, this is only my OPINION... nothing more) is based on what I have seen and learned on this board and on the other slant six.org site.
So, act accordingly... none of this is etched in stone.
First off, you probably don't know that a turbo slant six is a very different animal in this respect: These engines perform their best when "held back," like a "high-gear-only" fuel motor in a TF dragster. That is, they LIKE axle ratios in the 2.00's, not 4.56s... The really good running slant six turbo cars use 2.76:`1 gears on the drag strip. The bonus of that is, they are geared for both the highway AND the drag strip with a 2.76... making for no necessity to
ever change the axle ratio... ever. This allows you to use an 8.25" unit out of a late A-body and not worry about outfitting a more expensive 8.75", drop-out housing. I know you already have one but you won't need it. You can find an 8.25" with highway gears in a junk yard and bolt it in, instead... lighter and cheaper.
This will make unnecessary, the need for an overdrive unit. You'll already have a great highway gear!
Turbocharged slant sixes make ungodly amounts of torque... ungodly!
This makes finding a (slant six) clutch that will hold all that twist a difficult proposition. Also, the engines tend to be happier when hooked to an automatic, and the slant six automatic happens to be a 904, which is one of the all-around BEST 3-speed automatics ever to go down the pike. Do yourself a huge favor and hook that torque-monster up to a 904 with a shift-kit and you won't be sorry. Remember; no overdrive is necessary!!!
That is my BEST advice...
Next, I think the 2300 2-barrel Holley carb option is a great idea, on a super six intake manifold. Cheap, easy-to-find, and probably the best carburetion idea for a street/strip car like you want to end up with. I would avoid multiple carbs on this project as an unnecessary complication, having no real benefit.
I really like your MSD BTM idea.... should work well for you. I have one on my 360Maagnum/Vortech car and it has always performed flawlessly. I use it with an MSD Blaster II coil.
This setup you describe, if you get a water/alcohol-injection unit should allow you to run pump gas with 10-12 pounds of boost on the street. That will give you somewhere around 300 horsepower, I think, which should put your car into the low 13's. That's a whale of a lot faster than a stock 340...
This, like I said, won't be easy, but is the most fun you can imagine, once it's finished...
Good luck, and keep us informed!!!
