TVR S Series alternative parts cross-reference
This page lists the donor vehicles and aftermarket sources commonly used to keep a TVR S Series (S1, S2, S3, S3C and V8S, 1986–1994) on the road. Like most wedge-era and early-Griffith-era TVRs, the S Series borrows heavily from contemporary Ford running gear — chiefly the Sierra — which makes mechanical parts comparatively easy to source. Body, trim and chassis items are TVR-specific and harder to find.
Always check fitment against your own car before ordering: there is meaningful variation between model years, and some early cars use Saab hydraulics that were superseded on later builds.
Production figures
Section titled “Production figures”| Variant | Years (approx.) | Units built |
|---|---|---|
| S1 | 1986–1988 | 197 |
| S2 | 1988–1989 | 662 |
| S3 | 1990–1991 | 730 |
| S3C | 1991–1993 | 411 |
| V8S | 1991–1994 | 79 |
Brake system
Section titled “Brake system”Most S Series brake hydraulics are based on Ford Fiesta Mk2/Mk3 components, with friction parts from the Sierra. A common upgrade for early cars is to replace the original Saab master cylinder with the later Ford integral-reservoir setup — see the brake servo replacement guide and the TRW PSA328 cross-reference.
| Component | Donor / source | Notes |
|---|---|---|
| Brake servo | Ford Fiesta Mk2/Mk3 (TRW PSA328) | Common across the S Series range |
| Master cylinder (early) | Saab, remote reservoir | NLA — upgrade to Ford recommended |
| Master cylinder (late) | Ford Fiesta Mk3, integral reservoir | Pairs with the Fiesta servo |
| Front discs | Ford Sierra | Standard fitment |
| Front calipers | Ford Sierra | — |
| Front pads | Ford Sierra (4-cyl spec) | Confirm by model year |
| Rear brakes (S1/S2) | Drums | — |
| Rear brakes (S3C/V8S) | Discs | — |
Brake fluid: use DOT 4 or DOT 5.1. Do not use DOT 5 silicone fluid in the standard system.
Brakes are safety-critical. Match parts to your specific car, bleed thoroughly after any work, and torque fasteners to the manufacturer’s spec.
Suspension and steering
Section titled “Suspension and steering”| Area | Source | Notes |
|---|---|---|
| Front wishbones & hubs | Ford Sierra-derived | TVR-specific geometry; check bushes |
| Front dampers | Some Sierra units fit | Confirm length and rates |
| Wishbone bushes | Powerflex polyurethane | Direct replacement available |
| Rear suspension | TVR trailing-arm design | Inspect bushes and dampers carefully |
| Steering rack | Ford Sierra (TVR-modified) | — |
| Power steering | Fitted to V8S only | — |
Engines
Section titled “Engines”The S Series used three engine families across its life. All three share parts with mainstream Ford or Rover production cars, so service items are inexpensive.
| Engine | Models | Donor / reference |
|---|---|---|
| 2.0 L Ford Pinto OHC | S1, S2 | Ford Sierra is the primary donor |
| 2.9 L Ford Cologne V6 | S3, S3C | Standard Ford Sierra V6 parts |
| 4.0 L Rover V8 | V8S | See the Rover V8 reference |
Fuel system
Section titled “Fuel system”| Component | Source |
|---|---|
| Fuel pump (4-cyl cars) | Ford Sierra |
| Fuel system (V8S) | Rover V8 specification |
Electrical and instruments
Section titled “Electrical and instruments”| Component | Source / notes |
|---|---|
| Instruments | Smiths gauges, commonly shared with other British sports cars of the era |
| Speedometer drive | Ford Sierra magnetic sender |
| Headlights | Ford Sierra on some variants — check year |
| Rear lights | Vary by model year; identify from your car before ordering |
Body and trim
Section titled “Body and trim”Most of the bodywork is TVR-specific glassfibre, but a number of small Ford parts appear on certain build dates:
| Item | Source |
|---|---|
| Door mirrors | Ford Sierra (some models) |
| Door handles | Ford Sierra (some models) |
| Windscreen | Ford Sierra (some years — verify) |
| Seat belts | Standard inertia-reel; check anchor reinforcement on older cars |
Wheels
Section titled “Wheels”- 15” alloys as standard.
- TVR “Spider” wheels offered on later cars.
- A 5-stud hub conversion is available (Sportmotive) for owners wanting a wider wheel choice.
Chassis and structural concerns
Section titled “Chassis and structural concerns”The S Series uses a tubular steel backbone chassis similar in concept to the later Griffith and Chimaera. Corrosion is the dominant long-term issue. When inspecting or restoring a car, pay particular attention to:
- Rear outriggers
- Floor pans
- Front lower wishbone mountings
- Jacking points
- Main chassis legs
Any serious rust in these areas warrants a proper chassis inspection, and likely partial replacement, before committing to mechanical work.
