Hi All, my name is TJ, living in Jordan. My car is Audi S4 with Tial 770 and has dynod at 570 AWHP on pump gas with 100% meth. My 2.7L TT engine was rebuilt by BAR tuning in Houston, TX and dyno tuned by EPL in CT USA before shipping it to Jordan in 2011. My next project is to install AZR heads (from a B5 RS4) which I just had rebuilt in Germany by Loba with stage III CNC and mechanical valve train. The heads are ready to be installed on my current block but then I thought why not leave my current engine together and have an AZR block rebuilt to go with the new AZR heads. I have heard that there some excellent engine re-builders in the UK that are capable of rebuilding a block to match the heads to form a 10K RPM monster, but I don't know any yet. By joining this forum, looking forward to learning more about how and who can help accomplish my plan. Speak to you soon. My best, TJ.
