Evo X Big Turbo Kit – Part 2


DSC_0016 Watching a turbo kit come together is always exciting to see, no matter what car it’s on. The intense detail that goes into every piece makes it not only a car part, but a work of art as well.

DSC_0173 DSC_0188And it just looks badass once everything is bolted up, and that big turbo stairs you in the eye. This Evo is craving its appointment with the dyno. Here’s a bunch of extra photos of the turbo kit for your viewing pleasure.

DSC_0287DSC_0343DSC_0559To top everything off we bolted a massive APR Performance carbon fiber wing to the trunk.  Big wings don’t work every time, but it definitely worked this time.

Evo X Big Turbo Kit – Part 1

DSC_0876Evo’s are one of our specialties, and when it comes to custom turbo kits, we’re the best in the business. This Evo X is going to get a PSI Proformance custom turbo kit, minus the intercooler which was supplied by the owner. That means exhaust manifold, intercooler piping, downpipe, etc is all going to be custom fabricated by us.

DSC_0580DSC_0891To help with power even more, we cracked open the head for some upgrades. It was treated to upgraded cams with valve springs and retainers to go along with them.

DSC_0989The exhaust manifold is getting mocked up in our jig to make sure everything fits flawlessly. Check back for more updates on this turbo build!




-We dyno tuned an Evo 8 with an Evo 9 turbo
End result: 362AWHP 335 ft-lbs at 25psi

-A TT V6 Camaro came in for new turbos.

-Lotus Elise: we fixed a broken oil pump then broke in the motor on the dyno.

-This stylish Magnuson supercharged Jeep has come in with some issues that need correcting, mainly hesitation. No problem!

-We had a turbo 350Z come in for multiple maintenance items: most gaskets, belts, turbo manifold crack repair,  and a dyno tune.
End result: 372WHP 362 ft-lbs

-We’re excited to announce Precision Turbo and Engine has released its new Subaru factory upgrade performance turbocharger capable of 500HP. Designed to be an easy bolt-on install for 2002+ Subaru WRX and 2004+ Subaru WRX STi vehicles. Featuring Precision’s most advanced and innovative technology, the new turbocharger (part number 10520301726) utilizes a 55mm Competition Engineered Aerodynamics (CEA®) CNC-machined, 2618-forged aluminum compressor wheel specifically designed for maximum performance and less turbo lag. All units will be equipped with Precision’s high-performance liquid-cooled, dual ceramic ball bearing Center Housing Rotating Assembly (CHRA) for faster transient response and added thrust capacity. We look forward to getting these into your hands!

200WHP N/A LS/VTEC Integra tune

This Integra came in a while ago with the LS/VTEC conversion already completed. It had a few issues and dynoed in the 150-160WHP range. The owner then picked up a new exhaust, installed Acura RDX injectors, a Walbro 255 fuel pump, & brought it back in for a retune. Using Crome, we tuned it to put down 197WHP with ease. Seeing no reason to push every last ounce out of it we left it at this conservative level in anticipation of a Skunk2 throttle body, cams, and intake manifold.

This is another car that may not have put down a lot of power, but shows what the right parts and good tuning can do. The next round of mods will put this well over 200WHP which will make this already fun car a blast to drive on a daily basis. Check back for updates soon!

If you’re looking for work to be done on your car or getting a custom tune contact us at the shop! With this nice weather everyone is on a mission lately.


RB25 single turbo swapped S13 240sx

Here we have a S13 240sx with a legendary Skyline RB25 engine swap. Along with the swap the car is running full supporting mods & a single Garrett 55mm turbocharger. Let me just say, the looks of this car may be controversial with the bright metallic blue paint, widebody body kit, old school non “fitted” wheels, and non “stanced” suspension, but there is no denying the sound & power the RB25 engine produces when modified correctly.

The car was a pleasure to tune & listen to until some small problems arose. The car was running an “ebay” turbo kit with a legit quality Garrett turbo. The external wastegate that was installed wasn’t functioning properly causing severe boost creep the higher the RPM’s climbed. While we wished the car was equipped with higher quality parts to help produce the true potential of this setup there was nothing we could do at the time. To make the best of this situation, boost was set to 14psi and revlimit was set to around 6,500 RPM’s. With keeping max RPM’s here it kept the boost from soaring up to unsafe levels.

Once again this proves that you should use quality parts when modifying your car. Luckily we were able to reach the 340-350WHP goal the owner was looking for, even though we really wanted to make 400WHP with this setup. If your looking to have your car tuned give us a call at the shop! You won’t be disappointed, our tune results & customer satisfaction speaks for itself!

Enjoy the sound of this JDM swapped beast:

400hp 18g Eclipse GST

We’ve tuned this car before, but we were still impressed when it came back in the other day. One of the cleanest/original DSM’s around anymore, and with only 69,000 miles on it your not going to see many more like it. Don’t let the unpainted ’99 front end fool you the rest of this car is original and ON POINT.

As tuning progressed on the dyno it was apparent the tires couldn’t hold the power in 3rd gear. Once dialed in the car was putting down 387whp 394wtq at only 24psi. The owner had 100oct in the tank, but we weren’t even using the gas to its full potential at this low of boost. The owner has some plans in the works to add to the car and bring it back in eventually. We can’t wait to see what he has up his sleeve.

Rotated 18g WRX tuned

Last week we had another Subaru in for a custom ECUflash tune. This time it was a ’02 WRX with a custom rotated turbo kit using a GReddy 18G turbocharger. With a unknown history 60k mile motor, and a host of other typical Subaru upgrades this is a classic do it yourself modified WRX. It’s a great feeling when you can help an owner finish his project by putting a solid tune on the car.

After fighting a few boost leak issues early on we were able to get back to tuning. Slowly turning up the boost the car was picking up power every pull. By 20psi it laid down 309whp on our Dynojet. The owner was extremely happy with it cracking the 300whp barrier & told us this car will have the most horsepower he’s ever driven or rode in. We felt 300whp was a good place to leave the car at for the owner to enjoy while working out a few other things on the setup.

Tons of big horsepower cars come in and out of the shop on a daily basis which can lead to expectations held high on every project/tune. This home built project making 300whp can show us all that even with “only 300whp” there is still people out there that enjoy chasing goals big and little. At the end of the day its the owner who will be driving the car day in and day out and if he’s happy nothing else matters.

600whp daily driven Evo 8!

A lot of you seen this red Evo 8 at the shop over the last few weeks getting buttoned up. The owner brought the car here for a full build after having the stock engine fail. He went with a 2.4L block, Eagle rods, Wiseco pistons, h11 head studs, Crower 280 cams, and all of the other critical components needed for big power. We have the machine work done on the engine and then reassembled it in house as well as the rest of the car. We chose a PTE 6266 turbo for the car based on past results. Over the last 2 weeks the car was base tuned, broken in, and then slowly raised boost on it. The car kept making power at low boost so last night we finally decided to turn the wick up. At 32psi, the car put down 602whp 516wtq! Between the twin walbro fuel pumps being maxed out and the stock intake manifold we had to stop tuning there. Once this car gets those two items addressed the car should be back and will make 650whp easily.

Check out the video here of it making 600whp pulls……

3 mods, +48whp gain! Another Evo X tune

Another local Evo X came in for tuning on Saturday afternoon. With the only mods being a single exit 3″ ARK catback exhaust, ETS intake pipe, and a Hallman MBC the car base lined at 302whp/301wtq at 21psi. Our resident tuner Steve then turned the boost up to 22psi and tuned the car to make a reliable 350whp/336wtq on our Dynojet. We’ve had multiple Evo X’s in for tuning and they continue to impress us with how easily and safely they make power. If you’re looking to have yours tuned please contact us at the shop. 215-361-7100

Another 400whp Eclipse!!!!

Yesterday at the shop we had this Mitsubishi Eclipse come into the shop for a dyno tune. The car was looking really clean with it’s sparkling green paint and fresh wheels. After a few pulls on the dyno, we all knew this car had the potential to make some good power. With some simple mods such as a bolt-on 50 trim turbo, and Magnus Manifold it was able to make 409whp and 390tq on 24-25 pounds of boost. With some cams this car could easily make 450-500 horsepower.
