This is a write up on Joe Z's LP-560-4. Joe also owned an amazingly clean black six speed Superleggera that we built for him. Over the entire time that I've known Joe, he has loved that Superleggera like a member of the family. Unfortunately, as many of you have found, you can only stay in love with a car for so long before you start wanting to search for greener pastures. About two months ago, as much of a surprise as it was to us, Joe said goodbye to the old Super G. He felt that it was simply time to try something different as well as the reality that searching for and building a car is often the most exciting part of being a car guy.
Before the Super G was even picked up, Joe had taken delivery of a gorgeous Verde Ithaca LP560 with the intention of leaving it alone. Well, that was until the first time that he drove it. I got a call within minutes of Joe's first drive in the 560. After having a 1250+ whp Superleggera, the stock 560 was simply unacceptable. Within the next week and a half, the car was headed to Florida to our shop.
Joe and I spent a lot of time discussing what he wanted out of this car in terms of aesthetics, power and drivability characteristics. Being that the good driving weather in New York was just around the corner and the car couldn't be tied up for months. We decided to build the car in two phases. We got the car in and immediately began working on an entirely new turbo system, being mindful of what the end goal was. We spent countless hours planning every detail of this new system in an effort to give it an OEM quality appearance, fit, finish and at the same time, be technically superior to all existing systems.
We also discussed a number of cosmetic changes to this car with the goal being to give this car a unique personality in the most tasteful manner possible.
I will put together and post a detailed documentation of this build with pictures, dyno sheets and some video. I hope that everyone will be able to appreciate what we've put together here and I would like to thank Joe for choosing Heffner Performance to build him another incredible Lamborghini.
Here is the car as it was delivered to us a few weeks ago:
The first thing that we did was get the car on the dyno to get some baseline power figures.
All of the factory components that will not be used were removed from the car and it is ready to have a turbo system built for it. The main things that we wanted to consider when laying this out are:
Component location. We wanted to keep the hot parts away from the cold parts. We wanted the intercooler away from the exhaust and wanted the air inlet plumbing to be able to take in fresh, cool air.
Overall function and expandability. We selected tubing diameters, intercooler core and turbochargers that would function very well at the bolt on level as well as perform efficiently when the car comes back to get turned up.
Appearance. We felt that the completed system should look like it belongs on the car. We wanted it to have the appearance of a factory installed system rather than stand out as something that was made in the aftermarket.
Drivability and reliability. All of our Audi R8's and LP560's that are factory equipped with Bosch electronics and direct injection are tuned through the factory engine controller and are still fueled through the direct injection system. The factory Bosch electronics system is really an incredible feature. It has full time, active wide band oxygen sensors, full time, active knock control as well as a number of other important safety features. This means that if you happen to fill up your tank at a gas station that has low quality fuel, the knock sensors will detect the detonation and remove the necessary amount of ignition timing to prevent you from damaging your engine. The wide band oxygen sensors constantly monitor your air / fuel ratio and based on their readings the engine controller immediately compensate for any changes in fueling requirements. If something is to happen that the engine controller can not compensate for, it will close the throttle bodies and trigger a fault code to direct you in the area of the issue. The retention of the direct injection, especially in a bolt on configuration, is essential for the prevention of detonation. The direct injection system introduces fuel into the combustion chamber precisely before ignition. This makes it very difficulty to detonate the engine. If there's no fuel in the engine early enough to preignite, it makes it hard to create detonation. This is incredibly important when you are working with an engine with a 12.5 to 1 compression ratio on pump gas and applying boost. Not every manufacturer of turbo systems for these cars retains these factory systems.
Here is the blank canvas, ready to be painted.
We began with locating the critical components. Exhaust tips can only go in one place so we located them first.

The guys at TIAL provided us with a pair of custom billet wheeled ball bearing turbos that will happily support 1400 whp. We chose to go with 3.5" tubing for the downpipe. As I stated earlier, we wanted cool fresh air going into the turbos so we located the air inlet plumbing next. This pretty much dictated where the turbos needed to go so we made a temporary fixture to hold them in place while we connected the dots.
We fit the bumper support on to make sure we had adequate clearance and plumbed the rest of the exhaust.
The completed downpipe came out to be a very clean, unrestrictive piece.
Then we went on to plumbing in a pair of TIAL 44mm MVR wastegates. We took the time to make sure that the exhaust flowed out of the mid pipe and back into the downpipe smoothly. This makes for very predictable boost control.
Next, we fabricate the intercooler. We started with a core that is large enough to handle double what we are making in bolt on trim.
We fabricated an air discharge end tank that will not restrict the air charge and will compliment the factory intake manifold nicely.
Then the air inlet end tank and air charge pipes are fabricated.
Once all of the fabrication is done, it's time to remove all of the parts for final finishing. The hot side received a 2000 degree black ceramic coating from Jet Hot. The cold side piping received a black wrinkle finish that looks just like the factory finish on the intake manifold for that OEM appearance. We machined a billet cover for the intercooler with our logo and raised lines to give an appearance that looks like it rolled out of the factory.
The finished product turned out incredibly well and clearly shows the passion that our team has for the fine art of automotive tuning.
