Report
I was recommended Enginetuner by a friend after my Subaru suffered a catastrophic engine failure, after ringing a few other companies around the country I then spoke to Alan down at enginetuner.
Alan immediately put me at ease and assured me they would get my car back to how it should be. He spent almost an hour talking through the process, a real credit to their customer service considering I wasnt a customer as of yet. At the end of the phone call I knew my car would be in good hands, two days later a flat bed came to collect the car arranged by enginetuner. Throughout the engine rebuild

I was looking to get my turbo rebuilt and various other upgrades for my Sti type r and I heard nothing but good reviews for Enginetuner so I opted to contact them and Im very glad that I did ! On arrival I met with Ben who walked me through the premises showing me the workshop and Various cars they were working on. With that alone I was impressed and decided that this was the right place for my car. After various discussions with Ben the general manager we came up with a plan and he gave me various options for upgrades and suggestions for improvements to the car. Throughout the whole process

Recently took my S15 in to be repaired after it being sat on my drive for 2 years. Ben and the team were very welcoming and gave me a tour of the place before I booked anything in. They managed to get the engine started within a couple of hours and we discussed further work that I'd like done - there was no push from their side to add anymore than I wanted. I'd definitely recommend using Enginetuner, they all seem very passionate about what they do and Ben was always more than happy to update me whenever I asked. Overall a friendly team with a lot of experience in their field, they've definitely
