Alan Jeffery

We are a Family run business, established for 30 years, evolving into a wide based tuning specialist, run as a department store for virtually any type of car. Our Subaru department is particularly busy, enjoying the benefits of some ten years of gradual development.

We are based in Plymouth, Devon, and we like it just fine here!

You can contact us via alan@enginetuner.co.uk or Alan Jeffery - Engine Tuner
or 01752 345880 if you fancy a private little chat with myself or Martyn.

We sell anything Subaru if we can, just ask us.
We offer whatever discounts we can for our own services, plus whatever else we can squeeze from our other suppliers, who include Cosworth, Cobra, Milltek Sport, Roger Clark Motorsport, Jetex, Co ordsport et al.

We offer turbos from all of the really good manufacturers, lately supplying roller bearing billet units made to our own spec, alongside turbos from Turbo Dynamics, Precision and Owen Developments.

We are (probably) more experienced than anyone else around with the use of a dyno, having had the benefit of at least one since 1977, and using them on a daily basis. Yes, we road tune as well as appropriate! We offer mapping for just about all the systems that matter, including Apexi, Autronics, Ecutek, Gems, Motec, Syvecs and Alcatek. Especially Alcatek, having been involved from the very early days, when a lot of other tuners didn't know how good it was... Martyn has been heavily involved in the development of this ECU, including proving a great many of the latest features. We also offer the excellent Toucan dashboard monitoring device, again offering a great deal of assistance to the designer during the early days.
We are now appointed dealers for the Link G4 + ECU for drive by wire cars.

We have a fully equipped machine shop and engine build clean room, and offer full rebuild and repair to a high standard, with proven results. We employ two highly experienced engine builders, adding up to 40 years of quality engineering. We supply our own development 2.1 stroker conversion, plus 2.35 and 2.5 conversions in abundance, alongside all the the usual head surfacing, pressure testing, engine boring and honing, full engine balancing etc. Our engineering standards are high, and our reputation for supplying quality products extends beyond our shores, with engines being delivered across Europe.



We are very pleased to supply winning engines for a number of disciplines, including Pro class Time Attack, in the form of Paul Doyle's superb classic Impreza.



We have a four ramp workshop to carry out any mechanical task.
We don't employ boys to do Men's work! My entire staff of seven have been with us for at least 8 years.

We can therefore remove, machine, rebuild, replace, refit and modify and tune and dyno the car, all in house. Anyone else you know of?

Call us anytime for a quote, chat, shoulder to cry on when you've broken it, or a free cuppa if you're passing.

I'd say this says it all as it happens!
