Once you get everything fabbed up, the car will be hardly lighter than a foxbody and really won't be much of a sleeper because maby at first glance but something just won't be quite right, and people will be able to tell, and for those who you can fool you probally can make the kill with just a 4 banger.
Big time. I used to drive escorts, my first car was a 94LX auto, ran 19.1 at 65mph down the quarter (I got bored watching, wanted to see what it was like to drive down the track) and my second one was a '95 GT 5-speed with the 1.8 DOHC Mazda motor, ran 10.3 in the 1/8th with about mid 75mph trap speed, that was when it was stock and me not knowing how to drive it. I looked into the GTX/GTR engine, the whole motor turbo and all used from Japan was about $3000 and makes over 300hp, but it would still be an escort so I got the real deal, 5.0.
