We all remember the war of words between Porsche and Nissan over whose 'daily-drivable supercar' was the fastest. Unsurprisingly, the internet was rampant with couch-experts comparing the two.

Inevitably, the discussion now extends to modified versions of the cars.

US-based tuner Switzer Performance has decided to weigh in, but instead of talk they've decided to do. The company has released news of its P700 package, a reliable 700hp (514kW) at the flywheel, for the Nissan R35 GT-R.

Switzer Performance has been a Porsche tuner for a fair few years, and received international awareness with the amazing 1000hp 'Sledgehammer' 997 Turbo.

While initially reluctant to work on the GT-R, Tym Switzer had a customer wanting to see what the car could do. Switzer says he has always been a fan of the car and so, despite his reservations, he got down to the job.

Taking it back to engineering principles, Switzer took to the car with a hod-load of sensors to figure out the best course of action in getting more heat into an already hot car.

After logging all the data, he combed through it trying to find out which of Nissan's components were already near their limits, and which parts were hardly taxed.

?I was always impressed with Nissan's application of certain technologies. One thing I was not impressed with was the amount of (aftermarket) 'fluff' parts I was seeing being distributed... I knew that it was important to take a look at what the car was reliably capable of, and what was really going on within the platform.

?We checked for pressure drops, temperature variations, everything.

"After replacing the stock turbos with application-specific custom units and our own unique MONSTER intercooler package, we slowly dialed up the boost, checking all the data again and again.

Eventually, we ended up going beyond the limits of the standard ECU calibrations and hardware, so we built the necessary components and the data-gathering started again.?

The result? Try 460kW and 790Nm of torque, measured at all four tyres. However, the beauty is not just in the raw figures. Switzer has already stated that he's not after an undrivable, overboosted, car.

?Since our client was looking to road race his car heavily, yet wanted the ability and convenience of not having to find race gas all of the time to enjoy the car, I wanted to lay out a combination that would make around 700hp at the crank without stressing the engine or transmission.?

The entire kit costs USD$16,650 (or around AUD$26,000). While that is not cheap by any stretch, for the amount of performance and engineering behind the package it isn't exorbitant either. Some of the Japanese tuners will charge that much for a bodykit and exhaust.

The question is, did Switzer Performance succeed? Unfortunately Switzer is still in the process of finalising the car, so the only video provided is on the dynamometer.

Perhaps we can wait for when the client takes delivery, and see what news surfaces of the Switzer GT-R's road racing and Autocross endeavours.
