If I could give this company a minus I would. I ordered an engine from this company after reading a few reviews they seemed ok and chatting on the phone all seemed well. I received the engine and all looked good. I fitted the engine and all went well started it and it fired up and sat there ticking over nicely. That's where the problems started. It wouldn't rev about 1600rpm and no matter what I did it still wouldn't. I put it to my local garage and they tried £4500 later and they STILL couldn't find the problem after changing everything that could be changed. I had to get a secondhand engine engine and first that. And now it runs ok. I called Engineered Engines and informed them of the problems and asked them to send another engine and they wouldn't, and said to me " do you want a warranty form or not?" To which I still haven't received a warranty form. I also haven't received the surcharge back and they got my old engine in January. I have called them, emailed them and I have not received anything from them. PLEASE, PLEASE DO NOT USE THIS COMPANY AND BEING IN SCOTLAND MAKES IT AWKWARD TO TAKE LEGAL ACTION & EXPENSIVE!!!
