A client drove down his Chevrolet S10. 

blog S10

This S10 is powered by a carbureted small-block Chevy 350.  It has a Holley 700 CFM carb.  Aftermarket headers are connected to custom side exit exhaust.  Power is delivered to the road through a TH350 automatic transmission.

Along with setting the timing, Russ had to change the jets in the carb. 

This truck put down 281 whp and 304 ft-lbs of torque.

From the factory, the Nissan GT-R makes about 445whp.  This is a lot of power for most, but some want to get more.  AMS Performance has developed their Alpha 6 Performance upgrade package to unleash the power that was held-back by the factory.  The Alpha 6 package concentrates on allowing the VR to breathe better by removing restrictive stock components and replacing them with high-performance engineered parts.

This package addresses restrictions in the exhaust, intake, and computer systems.  The Alpha 6 package includes AMS 90mm cat-less downpipes, AMS 90mm resonated mid-pipe, AMS 90mm exhaust system using stock appearing tips, Cobb AccessPORT tuning system, AMS calibration map dialed in for your car and conditions, and HKS Super Hybrid air filters.

With the Alpha 6 Performance Package, this GT-R made 549 whp and 604 ft-lbs of torque.  Those are some very impressive numbers.  We can't wait to install a Alpha 9 or even an Alpha 10 package on another GT-R.  Those two packages should make even more impressive numbers. 

We hope to have a video up shortly, so check back soon.

blog test fit gauges

Test fitting the new gauge cluster's front.  The gauges need to be repositioned to accomodate the new LCD screen that is mounted at the bottom. 

This LCD screen displays information about the transmission.  That information includes transmission gear, overdrive, line pressure, and etc.  The screen will also display the time.  The display will be nagivated with the use of the switch below the screen.  This custom LCD display is controlled by a custom programmed microprocessor. 

As you can see, major re-wiring of the Supra is still a work in progress and will continue.  Check back for updates on the progress as this Supra's interior takes shape.

You cannot judge a book by it's cover.  This saying goes the same for cars.  This is the case for one of our client's Toyota Supra. 

blog Jim Jr

Besides the Work VS-XX's in burning black finish, this Supra has a stock external appearance, however under the hood is a different story.  Some might recognize this Supra as the one we fabricated a custom turbo system for, http://tunedbypsi.com/blog-entry.php?Our-turbo-kit-is-complete-112.  The engine bay of this Supra is one of the better ones out there.  The attention to detail is impressive. 

blog engine bay

With the help of the GTX4294, this 2JZ puts down 612whp through an automatic transmission.  Needless to say, this is an impressive car. 

However, under the surface, the wiring in this car needs a little work.  Although fully functional, the appearance of the wiring throughout the car does not match the car. 

blog wiring mess

The wiring that you see before you was done by previous shops that this car has been to.  This wiring is the exact reason that this Supra is at PSI.  A Technician will be taking the interior apart to re-wire the car.  He will not only have to go through and decipher this mess of wires but will also be updating some of the interior.  This car runs an AEM EMS and a controller for the transmission, the Technician is making a panel for USB connections to these important electronic components.  He will also be working on modifying the gauge cluster to accomodate a new display.  Russ has a lot of work ahead of him but once he is done, the wiring will match the detail of the rest of this Supra.

Not all of our projects are large and extensive like our current GT-R and Continetal projects but are still as important.  We view each project with the same importance because to the client their project is the main one.  Recently a client came to us with his Cadillac STS and wanted something a little more aggressive under the hood.  A turbo or supercharger was not something the client was looking for but rather a custom intake system.  He did not like all the black plasitc under the hood. 

Alex Laventure began this project by removing the stock air box.  Carefully consideration was taken to ensure no check engine lights because of the modification of the intake system.  This car has a MAF sensor like a Viper we previously worked on and had issues with the MAF sensor.  After assuring no issues with the MAF sensor, Alex fabricated a simple, custom intake with a K&N air filter.

The stainless steel in the intake contrasts the black plastic covering the engine bay.  This small custom intake adds a more aggressive look to the engine bay.  By removing the airbox and replacing it with this custom intake also gives the car a more aggressive sound.  Overall this simple modification provides many asethetic improvements.

At PSI, we don't just throw an engine and transmission into a car for an engine swap, but make it look as if the engine was meant to be there.  We add finer details that add to overall appearance and functionality of an engine swapped vehicle.  The fabrication continues, on the Chevy Stepside L92 swap, with the exhaust system and a few finishing touches. 

blog stepside on rack

To muffle the V8, Alex Laventure is fabricating an exhaust system that incoporates two Magnaflow mufflers.

 The headers dump directly into a straight pipe that goes to two Magnaflow mufflers and finally exits out the side.

A crossover pipe is incorporated to equalize back pressure and give the exhaust a better tone.

The exhausts exit out behind the doors and right in front of the rear wheels. 

An upgraded fuel system was needed for this new engine setup.  A Walbro fuel pump and new lines and adapters were used.  The fuel pump and lines are tucked behind the frame of the truck.  However, they run in close proximity to the exhaust system and therefore need to be protected.

Often times in the automotive performance and restoration industry, clients bring their cars to us in various stages of the project.  It is our job to review the current state of the project and formulate a plan for bringing the project to fruition.

This was the case for a 1969 Ford Mustang Fastback that we are working on.

blog Masten Mustang drop off

The Mustang was dropped off to us as a roller with a bunch of parts in boxes.  We then laid out all the parts and began inspecting the car.  There were some areas that needed to be addressed before the build can continue.   We look forward to creating the car that the owner desires.  Check back for updates as the build progresses.

Currently building a Ford 460 for a client's 1969 Lincoln Continental. 

blog russ working on 460

This '69 Continental is undergoing a restoration and receiving upgrades.  This blog post is mainly about the 460 that will be powering the Continental. 

The build started by getting the block back from our machinist, who machined the the cylinders to accomodate the upgraded Keith Black 30 over pistons.  Edelbrock Performer RPM aluminum heads were secured to the block with ARP head studs.  A Comp Cam 34-225 cam is used along with Comp Cam Magnum roller rockers, 3/8th push rods, and hydraulic flat tappet lifters. 

This build is progressing fast and hopefully the Continental will be in the hands of the owner soon to enjoy.

Engine swaps have always been around.  People having been swaping large big-blocks in their cars for a long time.  Recently the Chevy LS engine has been a popular engine to swap into a wide variety of platforms.  The size and power of the LS V8 has made it a popular engine to swap into import cars.  We have put an LS into a Nissan 240sx and a 350z and currently working on putting an LS3 into a 280z. 

Evergreen Pro-Am Round 3 16

In this 240sx, the buit LS2 replaces the previously swapped in turbo SR20 that replaced a N/A KA.

The LS is a popular engine for drift cars because the powerband of the V8 is more linear than that of a comparable turbo 4 or 6 cylinder engine, which is ideal for drifting.

Along with these projects, we have started swapping different engines into older Chevy step-sides. 

blog stepside on rackWe are currently working on installing a L92 V8 into a 1979 Chevy Step-side.  This L92 has upgraded cams and puts out about 450hp.

A client with an FD RX-7 wants to fit wide wheels under the fenders.  The wheels he wants are Work Meister S1's.  But these aren't your normal size wheels. 

blog rx7 meister

He wants to fit 18 x 10" in the front and 18 x12.5" in the rear.  These Meisters are wrapped with Toyo Proxes R888, with 2285/30 R18 in the front and 335/30 R18 in the rear. 

blog rx7 wide rubber

The wheels, from left to right, new front, old rear, and new rear. 

Those tires are more like ones you would find on a Dodge Viper rather than a Japanese sport compact.  Needless to say, modifications to the fenders was required.  Alex Laventure started work on the rear fenders, which required a lot of work. 

The client provided fiberglass over fenders to fit the wide wheels.  These overfenders needed to be fit to the car.  Most people would simply cut, pull, and hammer the fender to fit the over fender and then rivet it on. 

This crude approach is not what the client or Alex wanted to do. Alex began by strippinig the paint and preparing the surface for cutting.  He cut the fender to provide the appropriate amount of clearance for the wheels.  He began fabricating a new fender section to replace the part that was cut out.

Inner fender was formed to match the curve of the fender. 

Alex then needed to form the new fender section and then shape it to match the curves of the car.

A client recently brought his custom designed 1957 Chevy BelAir SS down to PSI.  This was a long term build that ultimately yielded a beautiful showcar.

Designed by Todd Ebeling with illustrations by Eric Brockmeyer.

A quote from this car's website, http://www.tri5.com/the-concept-a-design.html, on the design elements of this "BelAir SS."

"For the color combo, how better than euro inspired a silver on red Mercedes roadster look. For the “Super Sport” inspiration, how about a powerful supercharged engine, red line tires, and a clean shave & haircut on all the gold BelAir emblems, replacing them with signature airbrushed emblems instead.  To add to the muscle car vibe, how better than a set of modern 5 spoke wheels with a twist, grayed out spokes and a polished lip, a throwback to the 60’s Early American ET 5 spoke mags. Add some shaved elements from the body, a center console, and some carbon fiber in the interior design, and you have the makings of our Super Sport Belair Chevy and our signature name “BelAir SS”."

Adding a turbocharger has become very popular with the S2000 community.  Many owners enjoy driving their cars and just want some more power.  The high reving VTEC F20's and F22's put out reasonable numbers but not enough for the power-hungry group.

Jason Oefelein has tuned his fair share of turbo S2000's.  The highest horsepower one he has tuned was an AP1 with a Precision 6262 turbo.  This setup put down 662whp. 

Here's the video,

Along with this 662 whp turbo S2000, Jason has tuned several 400+whp S2000's.  Recently, he finished tuning a client's S2000, which made 507 whp.

To control this turbocharged F20, an AEM EMS was used.  Providing more control than many other alternatives, Jason felt confident this setup would put down high numbers.
