More details on Lanzante's F1-engined Porsche 930 restomod

Not long after last year's Porsche Rennsport Reunion, we posted on Lanzante Engineering's restomod project with the original Porsche 911 Turbo. McLaren Formula One used TAG-branded Porsche engines for four years in the 1980s to win two constructor's and three driver's championships. McLaren sold 11 of those engines to Lanzante — nine of which have been raced, one with a win to its credit — and Lanzante is installing them into the original chassis of some 930s. PistonHeads stopped by the shop to find out more. By the end of its service in the MP4/3, the TAG-Porsche TTE P01 motor rang up 1,060 horsepower in qualifying and 960 hp in the race, revving to a 12,600-rpm redline. Porsche engine legend Hans Mezger had led the development, coaxing those numbers from just 1.5-liters of V6 aided by two large KKK turbos at a max of four bar. All that was fine for a time when F1 ran with unlimited testing and unlimited parts, but a modern owner doesn't want to pay five techs to live in his garage and keep his car running. Lanzante asked Cosworth to make the engine more drivable and reliable. Cosworth installed a new crankcase, adjusted the air-fuel mixture, and installed smaller turbos for quicker power delivery, decreasing max boost by 25 percent to three bar (43 psi). The redline has come down to 9,000 rpm, for final output figures of 503 hp and 310 pound-feet of torque. According to PistonHeads, power climbs a "steady incline to redline," and more than half the rev band delivers maximum torque. The 503-hp rating doesn't sound like much today, when a Mustang gets more than 700 hp. Yet the first 930 Turbos got 296 hp and 243 lb-ft from a 3.0-liter flat-six with one big KKK turbo. The most powerful 930 Flatnose worked up 330 hp and 347 lb-ft from a 3.3-liter flat-six. Lanzante's taken out a ton of weight, though. The TAG engine is already 220 pounds lighter than the 930's 3.3-liter; a new carbon fiber hood and engine cover, and aluminum door skins shed more pounds. The total package weighs roughly 2,430 pounds, which is more than 500 pounds lighter than the original Porsche Turbo. That includes the extra pieces needed to make an F1 engine power a passenger car. Lanzante had to swap in a 930 Flatnose front bumper, which replaces the fog lights for oil coolers. The team put radiators at the front of the car as part of a brand new water cooling system. The climate control is entirely electric, because F1 cars didn't come with HVAC.

Chris Harris hits the track with the Porsche Cayman GT4

The Porsche Cayman GT4 offers the first legitimate chance for Porsche's more compact coupe to really step out of the long shadow of its brother the 911. By placing the 385-horsepower Carrera S engine into the center of a Cayman and sweetening the package with a ton of truly high performance parts, the model can now really show off. The ever-enthusiastic Chris Harris puts on quite a display behind the wheel of the German brand's latest hardcore creation. As is his wont, Harris slides the GT4 all over the Portimao circuit with little wisps of smoke wafting up from its rear Michelin tires. However, what he gets really excited about is Porsche's decision to fit a real manual gearbox, rather than the PDKs rapidly taking over the company's highest performance vehicles. For anyone who loves seeing a sports car's oily bits, stay tuned all the way through because after hooning around for awhile, Harris puts the model up on a lift to find out what's so special. Porsche touts the GT4's 911 GT3-derivied front suspension, but this really shows just how many mechanical adjustments it offers the demanding driver. Related Video:

2017 Porsche 911 Carrera First Drive [w/video]

The second seismic shift in the history of the Porsche 911 is happening as you read this. The first came in the late 1990s, when air cooling was thrown out and a more modern, water-cooled setup was put in place. People freaked out, and prices of air-cooled 911s are now skyrocketing. But I'll argue that this second major change is an even bigger deal: The free-breathing, naturally aspirated engine is gone, in its place a smaller, more powerful, turbocharged lump. But there's no need to panic. Purists be damned; "no replacement for displacement" shouters be silenced. This forced-induction heart beats beautifully in the 911's rump. I'm behind the wheel of a 2017 911 Carrera S coupe, stopped at the base of a winding mountain road on Tenerife, the largest of the Spanish-owned Canary Islands off the northwest coast of Africa. A nearly identical 911 is ahead of me, piloted by one of Porsche's test drivers. The road is closed. Hired spotters watch the corners. I'm about to run up the mountain at full charge, Porsche's expert leading the way. This forced-induction heart beats beautifully in the 911's rump. Behind me is the new engine: a 3.0-liter, twin-turbocharged flat-six. At idle, it still has that unmistakably Porsche, horizontally opposed hum. I've got 420 horsepower and 368 pound-feet of torque to work with, increases of 20 hp and 43 lb-ft compared to the old 3.8-liter, naturally aspirated six. If I launch it, I'll hit 60 miles per hour in under four seconds. Power is routed through the Porsche Doppelkupplung transmission – the best dual-clutch tranny in the business – and the fat, 305-section Pirelli PZero tires out back get all that thrust to the ground. There's a strong engine noise, complemented by the sound of the turbos sucking in air via the intakes just below the rear window. And then there's the exhaust. The standard Carrera comes with two large outlets and the Carrera S replaces those with quad pipes. But I've got the optional sport exhaust, not pictured on the car you see here, with two round outlets moved toward the center of the 911's hiney. Not only do they look way cooler, they're a treat for the ears. The Spanish may have decided to tunnel through many of Tenerife's mountainsides, but the pleasure of punching the throttle and letting the exhaust sing easily makes up for any loss of scenic views. The Carrera S' full 368 lb-ft is available right from 1,700 rpm, and there's no lag prior to arrival.
