I retract all my previous statements about thinking twice about going turbo. I've got my car up and running now and most of the things that I read about blowthru setups being hard to tune and cast pistons exploding so far haven't been true(knock on wood). I don't have a wideband and I've set my timing by ear  and, I'm on pumpgas, the rumors about a boosted motor haven't been true for me. With that being said I will have a wideband and properley set my timing before I go to the track and try to get some numbers, but so far on the street with 7lbs looking at the plugs and setting the fuel pressure is all I've done. I learned alot along the way I figured I would pass on to those building a turbo SB, but take my words with a grain of salt because I am not a professional.... *Stock magnum manifolds are by far the easiest route, I tried headers and have one on the drivers side but run a manifold on the pass. side. If I did it over I would have used them on both. *My ebay GT45 turbo was nice and so far with about 50miles on it has shown zero signs of trouble. The 1.05 hotside is alittle big for a stock 318 it spools late but comes in hard *Air-to-air intercoolers take up alot of space. If I do it over again it would be air to water or meth. injection. *Ebay wastegates and BOV don't seem to be that bad. Mine are chinese knockoffs and seem to function ok although only time will tell *I run a walbro 190 pump and a mallory 4309 regulator. Both are cheap and seem to be ok for my application. I also love that I can't hear the walbro as opposed to my old blue pump. *My cheapo stall converter was supposed to be a 2200-2800. It pulls at about 2400 but is way too tight for my car and gear. If I did it over I would try to get something in the 2800-3200 range maybe more. I'm going to a glide anyway because the 904 is already slipping and its rebuilt *Don't drill out your PCVR's until you get it on the car and see how it runs...although this has probably helped me from going lean and killing my motor already. *Stock ignition has been fine so far but I will be going to an MSD BTM when I can afford it Just some things I was thinking about and thought I would share. I'm new to boost so this has been a learning curve but it's always good to share real life experience

I went through much of the same thing when building my first TT440 in 2001. Nobody knew anything about putting a carb under a turbo. It was either some sort of voodoo or or a money sucking folly. Most of the people on Moparts were knocking me down and saying I would fail horribly. A few guys stuck by my side and offered info they thought would help. As the build progressed more and more people came over to my side. Once it was running well I had the support of most Moparts regulars. I really needed that support because I never had much success with Holley carbs. It's sad to think that this setup made it into Mopar Muscle Magazine in January 2002.  It's a far cry from the setup that made Popular Hot Rodding in 2009.  Now, there are truckloads of info available on the net, both good and bad. If someone spends the time to do a little research building a blow through turbo isn't that bad. You still find naysayers but stick with it and you'll be fine. Now that I've played with EFI, I'm not interested in doing another blow through. Maybe your build will progress liks that through the years too. So far, it sounds like you've done a pretty good job. 
We are brothers and sisters doing time on the planet for better or worse. I'll take the better, if you don't mind.

The key to the blow through carbs success, is the carb hat you choose. I switched to EFI also and I'd never run a carb again either. Not because they don't work, but because EFI is so much better on a street car. O2 sensors and closed loop are a wonderful thing when gas is $3.50 +. Nice setup on the Valiant. I ran a Gt45 also, and it was a great turbo. 
I planned to go EFI when I first started but after spending wayyy too much money on trial and error building I was lacking the cash lol. I really want to find another Duster or Dart sport to make nice body wise and use all the things I've learned building this car to make the next nicer and more drivable. I've use this whole car as an expierment to test my abitlites. This is the first car I mini tubbed, added subframes, and moved the springs in. Sounds like little things but It pushed my abilites and I grew on it. Now I know what to do and what not to. Using nothing but a sawzall, hammer, and a side grinder I don't think I did too bad lol

hey man, would you mind sharing all the details of your build? as in what you have into it money wise and parts wise? I have been debating whether to throw spray or a turbo/blower on to my low compression 360 j/y motor
Parts wise, minus the headers,(use magnum manifolds, trust me), I've got about $800 in the hard parts. Almost everything in the build was from ebay lol so I saved alot of cash there. Some will tell you not to waste your time with ebay "junk" but all of my parts worked fine right out of the box. I can't say how long all of it will last but for the money you can just buy better stuff IF the ebay stuff fails IMO. I did have to upgrade my fuel system though and that added some to the final cost. I had a 3/8 line and an old single outlet fuel cell with a holley pump. I upgraded to a new cell, mallory 4309 reg.,a walbro 190lph pump, and a return line back to the tank. If you don't want to cut up your car, definitely go with meth. injection. A front mount intercooler takes up alot of room and all the piping and stuff adds weight. The $350 for a meth. system is better in the long run. The carb was easy to do...just a basic rebuild on a 650 holley. I did drill out my PCVR holes to 3/32 and it's alittle too much but has saved me from going lean. My 02 reads a steady .930-.950 milivolts until the secondaries open. I'm waiting on my jet kit to get here so I can up my secondaries to keep my full throttle from going lean. The cost and the installation cost all comes down to how well you can fabricate. I was somewhat out of my league on that part of it but learned alot and after messing up a few times I got it right. O yeah, definitely build a bracket to hold the turbo. My GT45 is heavy and would have probably already broke some of my questionable welds lol

Don't know how you did it that cheap man. I have $800 just in the raw pipes, bends, v bands, silicone couplers, fittings, etc. That's not including the turbos and WG's, and I was already running EFI. I used factory manifolds as well.
I probably have $100-150 worth of spare pipe leftover, but still.

wow, only 800 bucks? and that includes the fuel system stuff? Im definitely liking that! lol...I do have fabrication ability, and my dad and two friends have both done custom fab procharger setups a couple of times, so that will definitely help...If i could do it all for under 1300 bucks, that would be gravy! but usually stuff costs more than planned...im still just thinking about this. With those magnum manifolds, do they have to run flipped still?
You may be recieving a pm from me in the future to bug you some more, but a few questions for ya. That intercooler fits okay behind the stock grill? does it interfere with the hood latch, or do you have a glass lift off hood? Also, how did you go about choosing the proper sized turbo for your application? and what ebay seller did you buy from?

You can't 'flip' Magnum manifolds (or any SBM manifolds, really) and to-date there's only 1 BBM manifold that can be flipped upside down.
What you mean is 'swapped' side-to-side.
I jump on this whenever I see it so that newbie folks don't get confused...

how did you decide what turbo would best fit your application and hp goals?
You have asked this very same question on every board. I couldn't read the compressor maps either. Your BEST bet is to write down what your goal and combo is and give a reputable vendor a call and they can help you. This is what I did for my application. Still waiting to get it running to see if it all jives.

It's only been two boards actually, and Ive only asked twice because i haven't got a response lol...but i guess thats a good idea...just not sure who in the turbo world is good to call

I delt with Forced Induction. They are a vendor over on TTF. Good guys to deal with and good info... My plan was a 383 but the one I had a crack was found during magnafluxing. Every other block I found had some sort of damage so I had to go with a 400 bored .060 over. Hoping this is not enough cubes to make a difference with the 1.10 turbine housing.
Try googling turbo calculator. There are lots of factors when going with a turbo charger. I have used this one just for fun and it seems about right. However, it only gives Garrett Turbos as options.

I chose the ebay unit because of the price. I knew about what size compressor I needed and after doing some research about turbine A/R I decided that the 1.05 would work but be laggy off idle. I was shooting for something in the .80-.90 a/r range but for my initial build most of my choices were out of my budget. I figured I could get it running and upgrade when I have the cash. I wasn't concerned about all out track performance because it is mainly street driven.
Side note: After alittle bit of tuning today I realized that the 3.55's are kinda steep with the 904's first gear. It revs too fast and your going to second too soon. I may try the 2.94's I have but I'm going to wait until I swap to a glide before I change the rear gear
Have you done any research into the reliability of those ebay units like what you are using? the price is very reasonable, just wondering about the quality

there's at least one monster thread on tmf about the ebay units from people who have used them.
I don't think anyone has suggested you read Maximum Boost by Corky Bell. Feets will tell you to read it a couple times before you do anything to your car.

Did you get the smoking issue taken care of???
Yes I did! I reclocked my housing to face about a 45 towards my point where it re-enters the side of the timing cover and my oil issuse went away. I still have smoke on startup but I tracked that to a leaking intake gasket. I put metal gaskets on like a dumba** and they are leaking fouling my back two plugs That is today's project lol

I think the thread goes both ways, as you might expect getting a piece of equipment like that it really matters which lot parts were pulled from and who was putting it together that day. You might get a good one or you might get total junk.

Boy is that a true statement! That is how it is with Ma Mopar on their new cars.. But more towards the bad junk side...
With that said I have two of the ebay GT45's that i am putting on a 282 in a 69 dart.. I am doing it to have some fun and tinker with the car.. I am not building a race car or anything that I just have to drive everyday so the ebay way is the way I am going.. Some people have the $$$$ just falling out their bingo and can buy the very best out there.. Some of us do it for fun... Thanks for this post..
There's a forum where a lot of people are doing some heavy stuff with those turbos. Good luck to you. I've been thinking about it on my next engine which is going to be a big cube GM.
