One Fabricator, One Standard, Every Job
TW Engineering is bench work in the truest sense. Pipework is mandrel-bent, fitted and TIG welded by hand, each joint back-purged so it is as clean inside the pipe as out. Nothing leaves the bench until it is right.
Whether it is a full system for a road car, a lightweight set-up for the track or a replacement for a classic where the original parts are long gone, the approach is the same: understand the car, build it properly, and stand behind the result.

From First Conversation to Finished Work
Every job is owner-led and follows the same careful path, so you always know what is happening and why.
- 01
Discuss the Project
You tell Tom about the car and what you want from it. Every job starts with a direct conversation, not a form reply from a call centre.
- 02
Design and Measure
The system or part is designed around your car, measured and planned so the fit and flow are right before any metal is cut.
- 03
Fabricate and Weld
Pipework is mandrel-bent and TIG welded by hand in the workshop, back-purged for clean, lasting joints.
- 04
Fit and Finish
The finished work is checked, fitted or prepared for fitting, and gone over so it sits and performs exactly as intended.
Work You Can Trust Under the Car
A small, owner-led workshop that treats every job as its own project.
Direct With the Maker
You deal with Tom from the first message to the finished job. No middlemen, no call centre, no guesswork about who is building your system.
Made to Measure
Every system and part is designed around your car, not adapted from a generic kit, so the fit and the flow are right.
Built to Last
T304 stainless steel and hand-laid, back-purged TIG welds that stand up to heat cycling and the road for years.
Road, Race and Classic
From a refined daily system to a track car or a hard-to-source classic, the work suits how and where you drive.
