This is my 86 XR. I just bought it several months ago to tinker with. I had a 85 a while back I loved it. I bought this one to fix up and have fun with it. It has 157,000 km's and I bought it from the original owner. It had a new clutch put in and brand new 35lbs injectors. At first I thought I had a find, but knowing these cars, even with 157K on it it still had the typical problems. Cracked manifold, dried Valve Stem seals, rough idle. The first thing I wanted to do is replace the manifold. I bought a ported E6 off of Ebay for $76. Since I was replacing the manifold I thought it was a good time to do a few other things.
So I've done / purchased the following:
Cleaned and Polished Head
Larger SSTL Valves
.42 Lift Cam
Dual Valve Springs
Bosch By Pass Valve
Ford Motorsport FPR
I'm still putting it together so I have yet to see what I've done. The car had good performance to begin with, even with a cracked manifold, but I'll up date my page when I get it running. I realize there is more to this car then the engine. This car needs suspension, tires and a whole new interior. I know this ownership could be expensive, but I'm looking forward to this car changing in the next few years.
