00:02 - Welcome back to Hot Rod Garage presented by Lincoln Tech.

00:22 In this episode, we're gonna take our 1973 Dodge D200

00:26 12 valve Cummins swap that we have started calling

00:28 Roll Smoky, and I'm gonna double the horsepower

00:31 and torque on this thing with just a few basic modifications.

00:34 But first, get out your pens and pencils

00:36 and your laptops and your notebooks,

00:38 'cause Clarence Barnes is gonna take you to school

00:40 with this quick tech tip from Lincoln Tech.

00:42 (upbeat music)

00:45 Ever see fish eyes in a custom paint job?

00:47 They're those small circles that give the surface

00:49 a rough, wet look after the paint has dried.

00:51 Fish eyes are caused by a reaction between the paint

00:54 and a surface contaminant during the painting process.

00:57 The most common contaminant is silicone,

00:59 but oils from your hands and even detailing products

01:02 that inadvertently land on the body prior to painting

01:05 can cause the dreaded fish eye.

01:07 The only surefire way not to go fishing

01:09 with your next paint job is to be absolutely sure

01:12 that everything you bring into the shop

01:15 is free of silicone.

01:16 You also need to clean the body panels thoroughly

01:19 with a solvent-based wax and grease remover.

01:23 If you do get fish eyes, you're screwed.

01:26 The only remedy is to clean the panel again

01:28 with wax and grease remover, sand it down,

01:30 and fire up your spray gun again.

01:33 Lincoln Tech can teach you how to have a career

01:35 working with cars.

01:36 See lincolntech.edu.

01:38 So we've got my good buddy Brendan Jones here

01:40 helping us today.

01:41 One of the last things we did at my shop in Philadelphia

01:43 is we took Brendan's '78 Ford Super Cab truck,

01:46 we dropped it onto a '97 Dodge 3500 diesel frame.

01:49 That sort of started my love affair

01:50 with these 12-valve Cummins motors.

01:53 But like I said, today we're gonna double the horsepower

01:55 and torque of this thing, and it only takes a few upgrades.

01:57 We're gonna do a turbocharger, an exhaust manifold,

01:59 injectors, and then we're gonna do some fueling upgrades too.

02:03 And all that is gonna take this thing

02:04 from 160 to 320 horsepower,

02:07 and from 400 to 800 foot-pounds of torque.

02:10 First thing we're gonna do is yank this turbocharger out.

02:12 You ready?

02:12 - Yeah. - Cool, let's go.

02:14 So after 180,000 miles,

02:17 our stock turbocharger has seen better days.

02:20 So we're gonna upgrade this thing.

02:21 Now my buddies at Lemon Engineering

02:23 put together this Garrett GTX3582 ball-bearing turbo for us.

02:28 They actually found

02:29 that a Buick Grand National exhaust housing

02:31 is just about the right size,

02:32 and it's internally waste-gated,

02:33 so it's gonna work perfectly for this application.

02:36 With the stock turbo off,

02:41 we are able to yank off the stock exhaust manifold,

02:44 and I'm gonna replace it with this.

02:46 This is a three-piece cast high-flow manifold

02:48 from Diesel Performance.

02:49 Stock manifolds shrink over time when they crack.

02:52 The fact that this is three-piece

02:53 is gonna make sure that doesn't happen.

02:55 It's higher-flowing than stock,

02:56 and it has a couple of bungs here, that 4EGT probe,

02:59 so it's a really nice piece.

03:01 All right, I'm gonna cut the original V-band

03:12 off of this exhaust and weld on a bigger V-band

03:14 that works as our turbocharger,

03:15 while Brennan gets started

03:16 on the first of our fuel modifications,

03:18 which are these plus-40 horsepower injectors from BD Diesel.

03:21 There you go, Brennan.

03:22 All right, so we're gonna pull off this valve cover

03:31 and this intake manifold

03:32 and get these injector lines off of here,

03:34 so we can get at the injectors

03:35 and the delivery valves in the injection pump.

03:38 Yeah, what in the (beep) is it?

03:42 Oh, I think it's important.

03:43 Nah.

03:44 All right, so while Brennan finishes up

03:45 the injector install,

03:47 I'm gonna dig into this P-Pump,

03:48 or the P7100 Bosch high-pressure fuel pump,

03:51 and install the first of a couple modifications.

03:53 The first one is a fuel plate.

03:55 As I understand it, and I'm not 100% sure,

03:58 under full throttle and as boost builds,

04:00 this controls the curve of the fuel delivery.

04:05 It's stock fuel plate versus a number 10 fuel plate.

04:09 See, this one kinda looks like a ski jump over here,

04:11 and this one, sorta like a guy wearing a hat.

04:13 Obviously, a ski jump is gonna beat out

04:15 a guy wearing a hat every day.

04:17 Here's the thing, we're not exactly sure

04:19 (laughing)

04:20 how all this (beep) works.

04:22 I just don't know.

04:23 - We'll figure that as we go along.

04:25 - After some research, turns out the fuel plate

04:27 controls the amount of fuel delivered to the engine

04:29 as RPM increases.

04:30 - And that's it, move the shutoff arm, blah, blah, blah.

04:35 - And I had my buddy Rob Parsons

04:36 weld this aluminum 90 onto the compressor housing.

04:38 You should check him out.

04:39 His car is on the cover of Super Street this month.

04:41 It's red.

04:42 Let's get this on and get the turbo bolted in.

04:44 There we go.

04:46 (upbeat music)

04:49 The last thing we have to do on this turbocharger

04:55 is install the oil feed line.

04:57 You're gonna run a ball bearing turbo like this.

04:58 You wanna get an oil feed restrictor.

05:01 They have these cool fittings

05:02 with restrictors integrated in them

05:03 because they need restricted oil flow,

05:05 or they will smoke out the exhaust.

05:08 So let's put this in.

05:09 (upbeat music)

05:10 You don't put a restrictor in.

05:11 This thing's gonna smoke more

05:13 than your douchebag vaping cousin.

05:15 Nobody wants that.

05:17 (upbeat music)

05:19 I think it's cool.

05:21 It's not cool.

05:22 After plumbing the turbo to button up the engine bay,

05:24 we had to make a hybrid high pressure line

05:27 using the fittings from the D200 steering gearbox

05:29 and flaring it onto the Cummins power steering line.

05:32 For cooling, we used a radiator and hoses

05:35 out of a '93 Cummins Ram.

05:37 We welded a plate into our rad support

05:39 and made bolt-in upper mounts.

05:40 We used the stock intercooler from the '95 Ram 200.

05:43 It's got great flow and it's thin enough

05:45 to fit behind the D200 grill.

05:47 We mounted it by welding the '95 mounts

05:49 into the 1973 rad support.

05:52 To make the intercooler piping work,

05:53 we wound up cutting three inches

05:54 out of the stock intercooler piping on the cold side.

05:57 And it looks like if we weld that three inches

05:58 right back into the hot side,

06:00 that side's gonna work great too.

06:01 So this thing was meant to be.

06:03 Ha ha, all right.

06:04 (upbeat music)

06:12 So I found this cool four inch aluminized exhaust online

06:15 for like 300 bucks.

06:16 And you saw before I welded the proper V band

06:18 and made up to our new turbo on there.

06:20 I think it's gonna fit the truck really well.

06:22 I bought it for a '93 Ram 250 with a Cummins in it.

06:25 I don't wanna use the whole thing.

06:26 I'm gonna just jam it outside the truck

06:28 in front of the rear wheel,

06:29 make a lot of smoke and noise, should be cool.

06:32 That part fits great.

06:36 Super easy by yourself.

06:38 (upbeat music)

06:42 (metal clanking)

06:45 Now that we've got the engine and turbo all squared away,

06:52 we can turn our attention to this 47 RH transmission.

06:55 Now stock, this thing would have never held up

06:57 to the kind of horsepower and torque we're trying to make.

06:59 But luckily, BD Diesel outfitted us

07:01 with a full upgrade package.

07:03 So that package included an upgraded torque converter,

07:06 a larger pan, a stage four rebuild kit

07:09 with extra clutches in there,

07:11 and a valve body that they modify for more performance.

07:13 Now to be able to shift the 47 RH in our '73 D200,

07:17 I used a combination of 727 parts and 47 RH parts.

07:20 I pulled the shift selector right off that 727

07:23 and bolts right onto this 47 RH,

07:25 as well as the shift pivot mount.

07:28 With that stuff in place,

07:28 I just had to extend the shift linkage coming off the column

07:31 and it should work great.

07:32 (upbeat music)

07:35 (metal clanking)

07:37 Maybe.

07:48 All right, so the transmission went in really easily,

07:50 really straightforward.

07:51 I was a little worried about the transmission tunnel

07:53 clearance for those top two bolts,

07:55 because we have it jammed in there pretty tight,

07:57 but they weren't too bad to get to.

07:59 Now what we've got left is to bolt the torque converter

08:00 to the flex plate, install the drive shaft,

08:03 and fab up an exhaust.

08:04 This thing should be just about ready to drive.

08:06 (upbeat music)

08:09 All right, we've got it all back together.

08:30 I've got the alternator

08:31 and the fuel shutoff solenoid wired up.

08:33 Once we prime the fuel,

08:34 this thing should fire up and be awesome.

08:37 We drained all the fuel out

08:39 and you gotta like manually prime it,

08:41 'cause it's a diesel.

08:42 Gonna prime it a couple more times.

08:44 He's single, ladies.

08:46 (upbeat music)

08:50 (man whooping)

09:01 All right, we've got Roll Smokey all back together.

09:03 We threw the fenders, the hood, the front bumper.

09:06 I cut the grill out to fit.

09:07 We put a fresh black coat of paint on this intercooler.

09:10 I almost don't wanna put that grill back on

09:11 because this looks super tough.

09:13 All right, we're gonna break this thing in

09:15 and head right to the dyno.

09:16 (upbeat music)

09:19 (engine revving)

09:21 All right, we just got to West Tech.

09:43 These guys were nice enough to stay open for us

09:45 'cause it took us like two hours in traffic to get here,

09:47 which was a nice transmission break-in

09:49 for Roll Smokey here.

09:50 In as driven over form,

09:52 meaning we haven't turned the boost up,

09:54 we haven't played with the fuel screws, any of that stuff.

09:57 It's doing 290 horsepower and 730 foot torque at the wheel.

10:02 So we are already super close to our goal

10:04 because like I said,

10:05 these things respond crazy to modifications.

10:08 This thing is a beast already

10:10 and we are gonna make 320, 800.

10:14 That's gonna happen.

10:15 All right, we're gonna try again.

10:16 (upbeat music)

10:19 EGTs are really low.

10:24 So I'm gonna pull some fuel out of it,

10:26 sliding that AFC plate back towards the firewall

10:29 and we'll see if it comes up,

10:30 gives us a couple more pounds of boost

10:32 and hopefully gets us where we need to be

10:34 for those dyno numbers.

10:35 (upbeat music)

10:38 (engine revving)

10:46 (tires screeching)

10:49 All right, on that last dyno run,

10:53 this thing put down 293 horsepower

10:56 and 755 foot pounds of torque at the tire.

10:59 So if you factor in driveline losses,

11:01 that puts us right at double the horsepower

11:04 and torque of the stock engine.

11:05 That's a win.

11:07 So that's it for our time with Roll Smokey over here.

11:10 In two episodes, we dragged that junk truck out,

11:14 took the engine out of it, took the engine out of this,

11:16 made mounts, made a transmission mount,

11:17 drive shaft, intercooler, radiator.

11:19 And then on top of that, we rebuilt the transmission.

11:22 We did big injectors, big turbo and a fuel plate.

11:25 So we made this thing run and double the stock power.

11:28 It was a lot of work,

11:29 but I'm really glad we got into it

11:30 because this truck is awesome.

11:31 It rules.

11:32 It's mine.

11:33 I love it.

11:34 It makes 300 horsepower at the tires

11:36 and almost 800 foot pounds of torque.

11:38 I can't wait to mob all over LA in this thing.

11:41 This truck rules.

11:42 This was a good episode.
