Just rebuilt the top end of my buddy's MA70 after accidentally dropping a valve when replacing stem seals required the head to come off. First start up went well and the new exhaust sounds pretty gnarly! I believe it's an RSR catback for a turbo, but it bolts up to his NA as well. Now it's waiting on one brake line and it should be roadworthy. This phase of the build included the refreshed head, new timing belt/tensioner, new water pump/thermostat, stainless lines from Technafit (one of which had a fitting snap when we were installing them and they graciously are sending us a replacement for free.99), Energy Suspension urethane bushings on the front (haven't gotten to the back yet, the front was a total nightmare which I can expand upon if you want), Whiteline sway bars (only the front is on right now, may install rear this weekend), and we have heim joint rear toe links and traction rods coming as well.
This was the third Toyota M-series engine (inline sixes) that I've done a head-off refresh on since March. The 7M-GE from my 1990 Cressida, the 5M-GE on my 1986 Cressida Wagon, and now the 7M-GE on this 1986.5 Supra. I feel very accomplished.
