Well. when I could get her to run right, she screamed. I ate 5.0's all day. I had a mechanic friend of mine help me with the engine part, the BIG jobs anyway. The Merks didnt have intercoolers from the factory unlike the SVO mustang and T-bird Turbo Coupes, So I added one from a late 80's 944. Then upgraded the T3 to a Grand National Turbo, ran 19 psi with ported intakes and heads. I installed a 9" ford with 3.73 gears and ripped out the T-9 for the infamous T-5 tranny. All in all, she scorched the earth, that is until I blew the head gasket and ultimately melted a piston to the cylinder! AHHH!
