The Chevrolet LS engines have now become very popular. We have been putting them into vehicles ranging from classic cars and trucks to imports. We are currently working on putting an LS3 e-rod into a Datsun 280Z. The client resides in California, therefore the LS3 e-rod package was chosen as the powerplant because of its emissions compliance.
We initial purchased motor mounts, however they did not fit. The motor mounts did not place the engine in an acceptable location, so Alex Laventure fabricated a set.
These motor mounts allow the engine to sit back and low to clear the hood. The mounts were test fit with a mock block and sit nicely.
The LS3 will be mated to a six-speed transmission out of a Dodge Viper. The stock Viper transmission is built to handle the high power of a Viper V10 and will be able to handle the power of this factory rated 430 hp V8.
A transmission mount also needed to be fabricated to properly hold this transmission. Slight modifications were required to get the transmission to fit and work properly.
A clutch from Monster Clutches will also be used.
This LS3 280Z project is progressing nicely. We hope to have the LS3 running in the 280Z by next week. Enjoy the New Year and don't forget to check back soon.
Welding is the joining of two materials by melting and adding filler material. Welding is something that takes a lot of skill to perform cleanly and efficiently. We are fortunate to have several employees with the ability to weld but our fabricator Alex Laventure is the best. He has been in this profession for over 18 years.
One current project Alex is working on is welding a custom exhaust for a Subaru STi EJ25 that will be going into a 914 Porsche.
This is the EJ25 with the exhaust and turbo mocked up. The client has spot welded the pieces into place.
Alex welded on the flanges. The tight turns and confines of this exhaust system took a lot of skill. Alex TIG welded the joints. Photos of the completed exhaust are unavailable because I left for a trip to Hawaii before the work was completed.
A client recently brought in his 2007 Cadillac CTS-V. This CTS-V was strapped to our dyno and put down whp and ft-lbs of torque. Those numbers are consistent with the stock LS2 that powers this CTS-V.
Here is a video of the dyno run.
Of course, client wanted more power than the stock LS2 could provide. A forced induction solution was the option that was chosen. The client opted for a MagnaCharger supercharger.
Billy Boat Long tube headers and a Corsa Exhaust were also added to this CTS-V.
The CTS-V is currently in the disassembly process.
Check back here for progress on this supercharged CTS-V.
Recently, a client brought in his 1999 Chevrolet Camaro for a dyno baseline. From the exterior this Camaro looks like any other LS1 powered Camaro. But this one is a little different. It puts down over 500whp to the ground. Typically, you expect to hear the whine of a supercharger. However, this Camaro is naturally aspirated. There is no ordinary LS1 under the hood. This is a fully built LS1. It has been stroked out to 457 cid and runs 11:1 compression. Here is the video of this 500+whp Camaro on our dyno.
Work on the wiring system continues on the 1994 Toyota Supra.
After disassembling the Supra's interior, the current wiring situation disected. Before a Technician could begin his work on the wiring harness, the current state of the harness needed to be returned to factory. This took a lot of hours of going through each wire and referencing wiring diagrams. Over the life of this car, it has been worked on by many shops before making it to PSI. Returning something to stock does not sound too difficult, but it actually is very difficult. Each wire needs to be identified and then tested. The resulting product will become the foundation for future modification, so one needs to be certain of its integrity.
Now that the wiring harness has been returned to the factory configuration, rewiring process can procede.
When working on custom projects, issues often arise throughout the build. The "Frankenstang" project was brought to us as a work already in progress. With those types of projects some inherited issues have a common occurance. Our first major issue with making the Mustang a running car is with the engine mounting position. The following photos show the clearance issues with the Ford 460's oil pan and the steering rack.
Alex Laventure needed to modify the oil pan to provide an adequate amount of clearance so that the big block will sit in properly.
The oil pan was cut to provide space for the steering rack.
This shows the cut oil pan and the clearance that is available. A;ex then needed to fabricate a new section of the oil pan that went around the steering rack but still left enough room for the oil pump to fit inside.
Here is the modified oil pan that is ready to go back onto the engine.
Alex is installing the oil pan.
Here is an undercar view of the installed oil pan and the clearance with the steering rack and lines.
Now Alex can procede to modify the headers to fit properly in the "Frankenstang".
The RX-7 that had overfenders attached by Alex Laventure is ready to leave to go to the bodyshop. For the build process of the overfender installation check out this blog, http://tunedbypsi.com/blog-entry.php?How-wide-can-you-go-160.
The client wanted 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. We accomplished it by installing overfenders in the rear and modifying the front end. An aftermarket bumper was used. Under the hood, some components needed to be relocated from the inner fenders, which were removed.
Here are some shots before the car was picked up by the client and taken to the bodyshop for prep and paint.
Fitment not only refers to how your wheels fit on your car but how all parts fit. A quality product will be able to bolt-on with out any issues. Developing such a product can often be a time consuming and costly endeavor. Technology has help tremedously in cutting costs. Engineers are able to design and test their new designs on a computer. But being able to actually had a physical product to test on a car is an invaluable resource. Getting that physical product is an advantage that we offer at PSI.
We currently opperate a 3D printer, which has the ability to "print out" automotive parts. We have been utilizing it for our projects as well as others in the industry. We currently rapid prototype parts for other local companies. Here are some examples of some parts that we have made.
The quality and fitment of these prototyped parts are precise. If you are in need of some rapid prototyping services, please feel free to contact us or stop in.
Knowledge is power. The more you know, the better informed decisions you can make. In a high performance car, there are many things that you want to have accurately monitored. The amount of boost that is being produced is one of them. The AEM Tru-Boost Gauge is a boost controller and gauge.
The Technician needed to run wires to the boost solenoid and a vacuum line needed to be run to the AEM Tru-Boost gauge.
The boost controller needs to be set so the Evo was strapped to the dyno for a little tuning.
Not all of projects are long-term and intensive like our current '69 Mustang project, but they are just as important. One such project was the installation of American Racing Headers and X-pipe install. This was a straight-foward install that has performance and sound benefits for the client. The American Racing Headers improve exhaust gas flow. At the end of the day, the client was happy when he picked up his Mustang.

With this rendering by Todd Johnston, in house artist, Alex Laventure, fabricator, began work on the custom hood scoop. When we left off last, Alex had just completed fabrication of the scoop out of aluminum.
Alex putting the finishing touches on the scoop.
It is now time to cut the hood to make room for the scoop. It is not as simple as it seems. A large hole cannot be simply cut out without affecting the rigidity of the hood.
To provide rigity to the hood, their are supports on the underside. This supports will need to be removed so the hole can be cut.
After the support was carefully removed, the hole can be cut. The supports will need to be put back after the scoop has been glued in.
After the scoop is glued in, work on the supports can continue. The scoop was glued into the hood because of the thickness of the scoop and hood. The aluminum hood was very thin.
Alex fitted aluminum under the supports that he cut so that the removed support piece can be glued onto them. This will allow the support to be firmly reattached.

The support was reattached. Alex then needed to use all-metal to smooth the transistion from the scoop to the hood.
Here is the hood hanging with the scoop in.
After Alex finished preping the hood, it was sent off to the body shop for final prep and paint. Check back for updates when we get this hood back.
What will replace the Cobra 460?

How do you improve on a video game setup made from a Dodge Viper? You upgrade the television. Recently, we got the newly released Gran Turismo 5 for the Playstation 3. The current television was a nice 52" LCD set but it was lacking something. The new GT5 has support for 3D so of course we needed to upgrade.
A Sony 55" LED LCD 3D television was purchased.
This is the new setup. Unfortunately, I have not been able to take the picture in 3D. But this new setup adds even more to the "driving" experience.
Andrew Coomes, AJC Drift, was down here to go over the work that needs to be done to the LS240 for next drift season. The off-season work will include an engine overhaul, fixing broken parts, improving the car, and making sure it complies with the new 2011 rules for Formula Drift.
Keep following this mini-blog series on the off-season work being done to Andrew's LS240.
A client recent brought in his 2004 Dodge Ram 2500 for some performance upgrades. We currently have his Lincoln Continental that we are doing an overhaul on. The Ford 460 has been rebuilt and put back inside. But more about the Continental project later.
The client wanted a little more power from his Dodge Ram. We started by allowing the 5.9L Cummins turbo diesel breathe better with an aFe Power Stage 2 cold air intake system and a MBRP Performance 5" turbo back exhaust.
aFe Power Stage 2 Cold Air Intake System
This intake system features a 16 gauge, powder-coated heat shield, heat-insulating molded plastic tubing, and a washable/resusable conical air filter.
To get the full advantage of these modifications, a Edge Products' Juice control module and Attitude CTS monitor were installed.
With the Juice, the timing and duration of injector firing is controlled. The Attitude CTS monitors the trans temperature, trans lock, trans slip, intake temperature, throttle position, fuel pressure, boost, EGTs, engine load, RPM, and speed.
