Lee Janssen's TR6

TR6 Information

My TR6 is a modified 1974 model (serial number CF12681U)

Upgrades?

Some would call it butchery to modify a TR6,

but not me!

With over 90,000 units built it's certainly not a Lotus or a Ferrari!
In my opinion a "1974 factory original" car handles like a pig and accelerates like the Goodyear blimp!

Engine

Modification of the engine compartment has been my primary focus on this car. Simply stated I'm trying to understand what does and what does not make power in a TR6. Most of the modifications have been to the inlet side in an attempt to reduce inlet restrictions and to increase fuel metering efficiency.

• Stock engine configuration with the exception of the porting of the head.
• Garrett T03 Turbo with a 0.63 A/R exhaust scroll and 60 series compressor.

Brakes

Electrical

• All relays replaced with MODERN components.
• Additional relays installed for main and high beams.
• Ford Fiesta alternator upgrade with custom wiring harness. (link)

Body

• silly racing stripe down the middle.
• modified color - anything is better than French Blue (too gray for me)!
• non standard surrey top.
• front spoiler.
• Subaru GL10 seats - I simply couldn't resist buying comfortable seats for $50 / pair. At the time miata seats were not widely available. Currently I would investigate miata as the first choice. There is a wonderful explaination on installing miata seats in a triumph at: miata seats
