    Funny idea, interesting project.

    So for a while I've been considering the addition of boost once I do my HO/347 swap. Because I live in commiefornia I have to pass bullshit smog every 2 years, which consists of not only a tailpipe emissions test, but a visual which includes scrutiny of "performance" parts. Anyhow, this is one of a list of reasons I got rid of my '98 p71 and bought a '90, not to mention I like 5.0 pushrod motors better. Anyhow, there are more CARB-approved performance parts available for the venerable old 5.0, including supercharger kits. Unfortunately, stupid Ford decided to make panther accessories a stupid mess instead of using the simple HO accessories and belt-routing. I considered converting to an HO accessory drive to allow for the installation of inexpensive and easy-to-find mustang supercharger kits. However, with some consideration I decided that would be a bitch for a number of reasons.

    Then it crossed my mind; they used to make a bolt-on twin-turbo kit for the fox mustangs that was actually smog legal here and even used the factory(mustang) exhaust downpipes. Being that my exhaust system consists of a mustang h-pipe, this works fine. Only downside is that these kits haven't been made in over 10 years and most people that have them seem to think they're made of gold. Anyhow, if I can find one for the right price, i'm buying it. The basic kit makes fairly low boost out of 2 little turbos, but they produce a fuck-ton of torque, which is what a 2-ton boat needs.

    All that aside, I've been considering a funny experiment: I'd like to get this kit and install it on the lo-po before doing my swap. Just think it would be hilarious to see what kind of numbers this turd makes, and how it drives. While i'm sure it won't make it a mustang-killer, it certainly would liven things up and maybe surprise a few people. It obviously is a bit sketchy but my confidence is slightly boosted by the fact that because my car is a '90 California car, it's a MAF car already so everything is pretty much plug-and-play. Intake piping will need to be modified a bit to account for the backward intake manifold, but aside from that and possible clearance issues, it should all go right in. Obviously it would benefit from custom-tuning, but I don't plan for this to be a long-running setup, just a funny experiment. All I need is a couple grand to spend and somebody to sell me a kit that doesn't smoke crack. Sound like fun?

    Good luck in finding the fox twin turbo kit. Did you ever go to the car part swap meet in Pamona ? They used to have them once a month at the speedway.

      My biggest concern is fuel. 14lb injectors ain't gonna cut the mustard even with a boost in fuel pressure. You can try it but you'll need to monitor the air fuel ratio pretty close.
      I think the Lopo would make an excellent low rpm torque monster though.

        not a chance in hell of feeding it with a 14# injector. If the ECM can be programmed, you can run anything you want. If it can't be programmed, install it in the circular file and use one that can be programmed.

          I'd be more concerned about piston strength than injector size...

            I would think piston rings on cast pistons need to be re-gapped at the minimum if you go more than about 6-8psi boost. And since that requires removing all that... might as well upgrade the pistons and rods and associated bearings while you're at it.

              fuck it, bolt it up and see how long before it melts.

                This was a semi-well-engineered kit back in the day. Some of you who've done fox mustangs may remember it marketed as DDMI and later INCON. It included a maf and I think larger injectors as well. With EEC-IV computers, aftermarket MAF's "calibrated" for different injector sizes used a different sampling tube to trick the computer basically. As I mentioned, my car uses a MAF computer and can account for changes better than SD setups. My previous '90, you may recall, had shortly been upgraded with heads, and intake, throttle body, MAF, 1.7 rockers, and larger injectors. While it initially had some mild crankiness, it was starting to run pretty happy about the time that assclown decided to wreck me. I literally didn't even get through a full tank of gas so the computer was still sorting itself out at that point.

                Yes I know that shitty stock cast pistons are not ideal, but as mentioned, these are low-boost, average about 5-7psi depending on setup. With the turd lo-po spinning it, probably low although there's not as much volume to fill so who knows? Either way I figure it'd be entertaining. I have located a few kits but most of these people are out of their goddamn minds with the price they expect to get. $3500? They didn't cost that when they were new 15+ years ago! Once the right deal comes along, i'll get one by damn, and would like to fuck around with the lopo before the good motor goes in. Hell, I might even sell or trade my 347 shortblock to get one of these kits so it lights a fire under my ass to get a good block for a stroker and not use a shitty stock block. I dunno, just sorting through a lot of crazy ideas while I have no time to play with my car. Either way I really do want one of these kits because it'd be a TON of fun on a 347. Triple the stock horsepower anyone? Yeah, that'd do.

                  There's actually an Engine Masters episode on this but they couldn't kill the 350, it even made north of 700 HP.

                    60lb injectors at least for boost. Obviously you'll need fuel pump to be able to deliver that amount. I have 60lb injectors in mine. Only because they were cheap enough to do that vs lower rated injectors. I believe Logan ran the same 60lb injectors in his 351 turbo build. And that thing ran great, besides the mishaps unrelated to fueling.

                      They did gap the rings though.

                        Which seems to be all they need to live, at least in short bursts.. On the other episode they killed a 350 with stock rings..

                          So i'm working essentially a 12-day week trying to stash some extra dough to sponsor this project. Been daydreaming about it for a while and even found a couple kits last year, but these guys were smoking crack on their pricing. My goal now is this turbo kit and i'm goddamned gonna get it. Project Lo-Po ecoboost is going to happen! Going to put the badge on the car too. Should be able to save enough in the next couple months and then hunt the proper kit in earnest. Once acquired, I smog the car in march/april and once that's done it will go under the knife. Plan is to get the kit on with whatever size injectors it comes with(I believe 42#) and the bigger fuel pump I already have. Probably leave all the LoPo top end on just for kicks then maybe change a few things. If everything goes on and works alright, it will see the dyno and be reported in earnest, as I've decided that if nothing else, this will entertaining as all fuck.

                          Also, once I've financially recovered and get my shit together, I can stick the 347 in this turd and with the turbo kit it'll be a rocket. I should probably improve the brakes and rebuild the front end too but whatever, one thing at a time. I need faster!

                            Dude, you need to watch the episode of RoadKill where they simply took a 5.0 HO out of a Rustang and threw some sort of factory turbo on it. I think it made over 600 HP. Probably waaaay cheaper than having a shop make you an engine. The Dyno curve of said engine was quite impressive. Freiburger admitted that "Ford made a good motor" in conclusion.

                              Saw that one, it was the power-stroke turbo they had on that shitty 4.3 before. I love that show. Problem here is I have to contend with the smog Nazis or pay somebody for a "special" smog every couple years. While plenty of folks do it, I hate paying extra money every 2 years, and there's no guarantee that the people who do it will be there after the next 2 years. The kit i'm after is the only one that is "smog-legal" here so it's that or I switch to HO accessories to take advantage of the jillion fox supercharger kits available.
