This is my 1986 Merkur XR4Ti. I purchased it in 2001 as a rolling chassis. The engine was gone, as was the driver seat and passenger window. It was originally eqquipped with the T9 manual transmssion, but was replaced with a T5 from a 1989 2.3L Mustang. I finally got the car on the road, running under it's own power in November 2007.
The base engine was pulled from a Mustang II in the junkyard. Someone had swapped a 2.3L Turbo engine into the Mustang II. I sent the engine to Race Prep in Bermuda Dunes, CA to have it rebuilt. They added Wiseco forged 8:1 pistons, Crower 5.5" rods, and ARP studs. The cylinder head was treated to larger 1.89/1.59 valves and porting by Bo-Port Racing Heads in Fremont, CA.
Other than the engine rebuild and welding of the exhaust, I have done all of the work to this car myself. It's been a long project and still has a long way to go. I have a lot of upgrades in storage waiting to go on.
