The Daytona Project

[Jeff]

The engine we are building is a modern take on the original Super 60 package (S-60) that was available from Mopar in the 1980s. This package consisted of the following
- Stock T-II (turbo II) engine (2.2L from a car w/ stock intercooler, forged crank/rods)
- High-lift camshaft (slider/friction type)
- Mild port ÔÇÿGÔÇÖ (ÔÇ£bathtubÔÇØ) head. (OEM 1982-1986)
- Performance Computer
- ÔÇ£+40%ÔÇØ injectors
- Holly 155lph fuel pump
- Turbonetics/Mopar ÔÇ£Super 60ÔÇØ turbocharger w/ .63A/R Exhaust hosing
- ÔÇ£IndyÔÇØ intercooler

This package made 300hp/300lbft. Pretty damn good from an 8v engine with nothing but bolt-on parts. It was developed and tested by Shelby. Many people try to assemble it from used parts these days but it is so antiquated, there are ways to make more power with less money, which is what we are doing.

We started w/ a NON SHELBY 2.5L engine from an 89 Daytona ES. This engine was non-intercooled and sported the small Mitsubishi turbocharger. It was designed to be the smoother, torquier engine for the more ÔÇÿluxuryÔÇÖ ES Daytonas, Minivans, Lebarons, and others. It spools faster to its max boost of 8psi due to the smaller turbo and has more bottom end torque to make the lag less noticeable, and more v6 like.

That having been said it is not a performance engine we are dealing with here. It lacks the forged crank of the TII engine, but its cast crank is 12lbs lighter and just as strong well above 400hp. Its stock state lacks any form of performance good.

I know this is long but you can see where explanation of the basis was needed. We have all the components of the S-60 package and then some. Every system has been replaced and upgraded to AT LEAST the S-60 standard. We have about 80% of all these items at a cost of about $2500. I hope this helps inform and interest people in my project, and questions or comments would be great.
