Is your F40 with F40LM turbo upgrades feeling a little sluggish? Want the classic “Magnum–esque” look of the 308/288 but with a massive amount of oomph? Here is the car for you. No one would ever call it a sleeper but anyone that doesn’t respect its power to weight ratio is in for a VERY rude awakening. Play for pink slips with this beast and you’ll have a garage full of cars in no time.

1981 Ferrari 308 GTBi s/n 034555, originally a USA model, now a tasteful but wild 308/288 GTO conversion finished in very good black paint with a full carbon fibre interior including carbon fibre seats covered in red cloth.

The body is a full look–alike 288 GTO body complete with fender shields, big flares, splash guards and the correct vents. There are no headlights, although there are Hella driving lights. The car also has correct modular deep–dish centre–lock wheels with highly polished rims and a 288 GTO Evoluzione–style adjustable rear wing wrought in carbon fibre of the highest quality. The air intake ducts for the motor are beautifully made carbon fibre and are aesthetically pleasing as well (these alone were about $10,000). The shut faces of the engine compartment are also carbon fibre, as are the insets of the front NACA ducts and air extractor duct from the radiator. The front screen is Lexan and all of the other windows are Plexiglas. The door windows have sliding side windows, la F40 LM. The engine cover is also Plexiglas, allowing a view of the 328 Quattrovalvole–based engine.

The interior features extensive use of carbon fibre. The sills, dashboard, floors, doors panels, rear view mirror and Sparco seats are all carbon fibre (a carbon fibre OMP competition seat is also included with the car). There was no expense spared in shaving excess weight off this car. If it could be made lighter, without sacrificing quality or safety, it was. There are also 5–point Sparco full competition harnesses and a chromed SCCA–approved roll bar. The interior carbon fibre is the yellow and black weave type more commonly seen in F40s. The interior also includes a state–of–the–art Motec digital instrument cluster; sundry other gauges and drilled aluminum gas, brake and clutch pedals. The information provided by these gauges include manifold pressure, charge temperature, exhaust temperatures etc. The dashboard itself is covered in stitched alcantara. Between the seats are knobs for the adjustable turbocharger boost and for the brake bias.

The engine is a very “trick” 328–4V with F40 head gaskets, special head studs by A.R.P., Carrillo rods, a dry sump oil system, big oil coolers, twin intercoolers, and twin Turbonetics turbochargers running ~7–10 pounds of boost. There are also direct atmospheric wastegate pipes that exit below the license plate next to the outlets of the straight exhaust. The engine is mounted in–line with a Porsche G50 5–speed gearbox and connected via a Tilton racing clutch and aluminum flywheel. The engine is fitted with a Motec engine management system, Motec wiring harness and a Motec digital dash. The engine and gearbox rebuild were done by Carobu Engineering, one of the best Ferrari engine shops in the country, between January and March 2002. The twin turbo 4–valve 328 engine puts out 530 hp at 7,500 rpm and a massive 420 ft. lbs. of torque at 5,700 rpm. The brakes are custom–machined Brembo components with two–piece rotors, aluminum hats and massive Brembo calipers. There is also an integrated OMP fire extinguishing system. To get all of this power to the ground, 034555 has new 265/45/16 and 335/35/17 tires!

The original conversion was commissioned by Mel Spillman and executed by Jim Carpenter of Arizona, who did many other 288 GTO conversions in the late 80s as well. It is estimated that Spillman spent about $400,000 on the car. The car was sold by the State of Texas to Miles Irish who spent about $60,000 with Carobu engineering to fit the Motec dash, engine management system and wiring, and to rebuild the engine, gearbox and brakes. The car was subsequently sold to John Goodman of Seattle who spent over $40,000 on race preparation, carbon fiber air snorkels, oil coolers and a thorough going–over (2002–2004) by Walter Gerber, former head of Porsche’s racing efforts with the Porsche Indy car team and the IMSA 930, 956 and 962 race efforts. The result is a car with dyno sheets showing more power than an F40 with the F40LM turbo upgrade.

The attention to detail throughout this car is truly fanatical and has to be seen to be appreciated. This truly unique and outrageously quick 288 GTO conversion is priced far far below the cost of construction at only $102,500.
