Typically of TVR, the SE range of Wedges represents a range of cars of very differing, and confusing specifications.

390 & 420 SE (1984 - 1988)

Early TVR 390SE		Later model 390SE

The 390 SE was introduced in October of 1984. TVR Engineering worked with Andy Rouse, a Rover Tuning specialist to produce a blueprinted engine, turning out an extra 85 bhp, taking it to 275 bhp. This was achieved by the following improvements:-

• Increasing bore of the engine to 3905 cc
  
• High lift camshafts
  
• Gas flowed cylinder heads with large valves
  
• Cosworth machined pistons

A stronger clutch, limited slip differential and wider Yokohama tyres were employed to help get the extra power down onto the road. The styling of the car was improved with a deeper front air dam, and a rear under body aerofoil. Fifteen inch wheels were part of the package.
The series II car appeared in 1985, with the most obvious changes being the (slightly) rounder styling. There were numerous other changes to the mechanicals.

The 420 was a customer "specified" 390 which took the SE range one step further, for customers with some spare wonga, you could get yourself another 25 bhp and, more importantly, another 20 lbs/ft of torque was found.

400 SE (1988-1991)

TVR 400 SE		TVR 400SE

The 400 SE was the last wedge to be manufactured, with production running until 1991, and the last car being registered in 1992. It was identical to the 390 but for the marginally larger engine.

450 SE (1989-1990)

TVR 450 SE		TVR 450SE

Guess what... another 212cc, 20 horses and 30 lbs/ft of torque in 1989. TVR were getting a reputation! The body styling was identical to the 400SE series.

350 SE (1990-91)

In the final years of wedge production 26 remaining 350i shells were used to produce the 350SE "Limited Edition"
which was fitted with the 3.9 Litre V8 from the 400SE. Each car was numbered but there was no number 13 making the total built 25.
