OK but if you want to be different and use a 6 cylinder
Move the engine and tranny forward 4.5 inches and then use the fuel injected apron to help hide the muffler.
You had better be good at making custom 1 off stuff.... Or be prepared to shell out $4000.00 + for some-one else to make parts for you.
You still need to buy the engine and tranny.
OR
Put a Porshe 2.0 in your car like mine...
and wish you had used the T1 instead...... You can buy my 2.0 for $4000.00... I'll even give you a ride in my car so you can feel the torque of the power before you buy.
