1974 Triumph TR-6

205 HP Turbo Charged EFI Triumph TR-6

You are bidding a 1974 Triumph TR-6 that I have owned since 1985. The vehicle is turbocharged with a Garnett T03/T04 turbo charger and equipped with a 18” Spearco intercooler

The vehicle has hit 205 HP at 10 pounds of boost using premium gas at 5000 feet of elevation as measured by a G-tech performance meter. Sea level atmospheric pressure is approximately 20 percent higher so there should be a commensurate increase in horse power.

A leak down test was performed last month after the engine had been sitting for 6 months – there was zero leak down in all cylinders (photos).

The fuel mixture ratio and spark advance is controlled by a Megasquirt V2.2 computer controller with a wide band oxygen sensor feedback. By using a laptop the Megasquirt engine parameters can be modified while you drive. For example; if you think the cold start idle is too low it can be changed with a click of a mouse. The included image shows the volumetric efficiency of the engine for various RPM and manifold settings – changeable with a click of a mouse.

The engine has approximately 25100 miles on a 1999 rebuild. Since everyone asks: the 12 inch long cylinder on top of the driver’s side wheel well is a Canton Racing Accusump – a pressurized pre-oiler and surge oil supply. Turn the key and the oil system is instantly pressurized.

The car has a Revington TR aftermarket fiberglass surrey top. The seats were replaced with those from a Subaru GL 10; originals are torn but can be recovered.

The car is equipped with a 1983 Toyota Celica 5 speed transmission with Herman van den Aker conversion kit. The differential ratio is 3.45 (obtained from a TVR) which is lower than the stock 3.71 - don't worry; the turbo more than makes up for the lower rear end (a spare 3.71 differential is available at an additional charge).

Suspension upgrades include 16X7 inch Panasport wheels with 205-55/16 General UHP tires. Goodparts front and rear sway bars and nylatron suspension bushings. Corvair rear axles with 3 inch studs from David Wingett and aluminum front hubs with 3 inch studs from Southwich Machine & Design. The front shock absorbers are Spax and the rear absorbers are KYB gas shocks riding on a Herman van den Aker shock conversion kit.

The braking system includes a set of Toyota vented front rotors and a set of 7/8 inch rear cylinders with Datsun 280Z finned brake drums.

The vehicle was appraised for $15,000 in 2002.

Included with the vehicle are 2 spare Megasquirt computers, a RS232 to USB cable, all vehicle computer data files, quart cans of touchup paint, a spare fuel pump, spare EDIS components, component documentation and the original seats which need recovering.

Most significant flaws are: a small crack in the windshield, 2 small dimples in the hood and a section of the carpet on the rear deck where a trouble light got too close and melted a couple areas. Photos are provided for all of these flaws so you can evaluate how important these issues are to you.

I have had a web site for my car since 2000 which documents most of the modifications (web page source code available on request).
