So, you are the proud owner of a brand new Dodge SRT-4 and you love the sound of boost. Better yet, you love how quick your little four-door is. The only problem is … you want it to be faster. The need for speed is killing you and you will do anything and everything to get your adrenaline flowing. You have seen Mike Crawford and Shaun Carlson go down the track in their very fast SRTs and now you want the same thing. 

Well, unless you have a whole lot of money in your pockets, don’t count on going as fast as those two just yet. But, get this: HP Racing out of Miami may have something that will wake you up. HP has a turbo kit you can really enjoy and best of all, afford. Yes, this is the same HP Racing that built that incredibly fast HB. It has now expanded its product line with a Stage 1 upgraded Turbo Kit for the new SRT-4.

Boost is good, but having even more boost is better. The HP Racing kit includes a T3/T04 Turbo, Turbonetics wastegate and blow-off valve, HP 2.5-inch to 3-inch downpipe, racing tubular header, all oil lines and all the gaskets and screws needed for a clean and simple install. With an HP Racing turbo upgrade, you can make your already quick car 95 hp quicker.

We had a chance to visit Lujan Motorsports in Miami as it test-fit and dyno-tested the new HP turbo assembly. As you can tell from the photos and straightforward steps, this install is quite simple and it looks great, too. William Lujan and Pablo Raffaele were interested in seeing what this new turbo kit would do on the dyno and to their surprise, the results were even better than advertised. The SRT-4 made 215 hp and 235 lb-ft of torque in its OE form. Not bad for an all-stock SRT-4, but these guys were looking for more.

They went through the installation, following the directions and keeping everything tidy. When it was time to see what the new kit was all about, the HP upgrade put out a very impressive 310 hp and 311 lb-ft of torque. Now that’s enough to wake up the SRT-4 and put it in anyone’s league.

We made sure to take pictures of the new component so you could see just how big the HP turbo is. If you are in the mood for some extra boost or just want to spank up on some unsuspecting sleepers, make sure to check out this new kit. By the time you read this article, it will be on the market and readily available. We caught this one early on, so we could provide you the heads-up. Now you can beat the rush.

All that is left for you to do is follow along as we show you the install, then go and tell your significant other that you now know what you want for the holidays. The kit retails for $2,400, which is a deal and a half if you consider the whole package. Your SRT will get a nudge shy of an extra 100 ponies and just as importantly, an additional 75 lb-ft of torque. HCI

1A,B. Here are a couple of views of the stock turbo to compare the size and space before the new T3/T04 was installed.

2. Notice the size of the new T3/T04 turbo. It is bigger than some peoples’ heads!

3. Although space looks tight, there is still plenty of room to install the new tubular manifold.

4. The tubular design will flow much better than the factory iron manifold and you can see from the many welds how much time went into the design of this bad boy.

5. Notice that it is a straight shot to install the turbo nothing is in the way.

6. With the thick mounting flanges, durability should not be a problem with the HP kit.

7. The overall packaging design is great. Some tolerances are tight, like the clearance between the cowl and the turbo, but everything fits nice and snug.

8. At this angle, you can see the fitment of the turbocharger in its new environment.

9. After the turbo and manifold are installed, you are ready to connect them to the new downpipe.

10. Notice how detailed Lujan is when doing an install. All the tools and equipment were set up before anything started.

11. The mounting flange between the block and the manifold is just as solid as the flange that connects the manifold to the T3/T04 turbo.

12A,B. A view of the turbo and manifold from under the car gives you some idea of how sanitary the whole deal really is.

13. A sweet-looking view of the downpipe going from the turbo manifold to the exhaust system.

14. This shot shows us a better view of how the downpipe exits rearward.

15. Before you install the downpipe, you will have to weld the pieces together.

16. One necessary step is to block off the water line. Water is good to drink, but bad for your turbo!

17. An optional step is to wrap the turbo piping in heat-resistant tubing to keep turbo heat from affecting other engine components. Color for the tubing is optional.

18. A view from below the Dodge: the new downpipe, dump tube and blow-off valve.

19. This is an ultra-deluxe picture taken from underneath the car, where Lujan installed the new blow-off valve onto the stock intercooler piping.

20. A side view of the TiAL wastegate (Note: the HP kit will come with a Turbonetics wastegate).

21A,B,C. Here are several different views of the finished installation inside the engine compartment. Now go out there and have some turbo fun!
