1971 MG MGB GT Additional Info:
Up for sale is a 1971 MGB GT with a AP1 F20c from a 2000 s2000 and 6 speed transmission.
The engine and transmission had about 45k when installed (wrecked s2000) and I have since driven thevehicle for another 10,000 - 11,000 miles. The engine is stock, aside from a remote mounted oil filter (oil filter clearance issues at stock location) and the air conditioning compressor. The A/C compressor is normally mounted very low and on the drivers side of the engine, fouling the frame. A Sanden knockoff was installed high and the serpentine belt was extended with an additional idler pulley. It has workedthroughtwo summers flawlessly, and I still run it with the Heat mixed to reduce humidity in the winter. The Serpentine has never torn in the 10/11k miles Ihave used the vehicle. The A/C unit has a heater core integrated, which is great for mixing the A/C with heat in the summer, and when the A/C is a bit too efficient. It also provides a tremendous difference in capability compared to theoriginal heater.
The body on the vehicle is in fair condition, no accidents or bent panels. Some rust bubbles in the common areas for this vehicle, and a dent in the drivers side fender (above the wheel) from a stone being tossed by the tire and hitting the panel from underneath. (noise was loud enough I though I had thrown a rod!)The exhaust is a 2.5 to 2 inch pipe, no catalytic converter (I actually had one on for about 2k miles, I removed it because the catalytic converter was just too low to the ground, I couldn't find a good place to mount it where it wouldn't catch on most driveways!) It has a SpinTechSportsman Street 3000XLF - Low Profile Muffler into amagna flow resonator, the exhaust is mellow at idle anddistinctively loud at 5,000 rpm through its 9,000 rpm redline.
The driveshaft is a custom piece made by a local driveline shop, specializing in hot rod/swap drivelines.
The high pressure fuel pump, and fuel filter were located in the drivers side storage/battery box, the fuel filter is of about 1 quart capacity, acting as aswirl pot/surge tank prior to the high pressure pump.
I had to notch the crossmember about 3 inches, it was closed and welded with 1/8th steel, along with internalreinforcements (steel bars running from one endtothe otherinternally) The assembly was closed up and stitch welded. Some seam welding was done around the engine bay seams to provide a bit more stiffness to the vehicle up front.
It has uprated brakes/pads, a de-pillowed dashboard (with crinkle finish) SpeedHut tachometer/speedometer, and is a absolute blast to drive.
The MG is a absolute blast to drive, the transmission is undoubtedly the best thing about theswap (aside from 220 hp and a 9000 rpm redline), the gear shift was relocated about 2 inches rearward from the stock MG location, I am 6' tall and this helps locate it to where my hand rests when the seat is all the way rearward.
I installed seats from a 90's Miata, and have the headrest speakers wired to the stereo. I was in the middle of redoing the interior when I decided to sell the vehicle, I wanted to create a new center console with a hand hold similar to a F-type. This is why I never finished off the shift boot, or the radio console.
I have replaced the leaf springs, bushings and pads, along with updated the rear lever arm shocks to modern shocks.
