Custom 3.0L/A543 1991 Dodge Spirit R/T

Post by nmw2006 »

Hello All,

Just adding my success story to the findings of others for the purpose of helping the community.

My vehicle is a 1991 Dodge Spirit R/T that I bought as a roller. IE. no intercooled 2.2L 16v Lotus turbo toys :cry:

Anyhow it is now sporting a 3.0L Chrysler V6 and an A543 manual transmission and is now running on MS2Extra 2.1.0. Sleeper FTW!! :yeah!:

For more info on my car and many others like it check out this page on - ... hp?t=35628

MS2Extra code vs. 2.1.0 w/ Launch control/Flatshift enabled.
Ported/Polished intake manifold opened up for a Jeep 60mm TB.
Custom reground Crower camshafts (reground for turbo, but make great N/A power too :D )
Custom underdrive crank pulley.
Fidanza Aluminum Flywheel and stock clutch/upgraded PP
MSD Blaster2 Coil w/ Aurora 10mm wires and NGK copper plugs
A/C delete
Solid motor mounts and bobble strut.
Full 3" exhaust system with high-flow cat and magnaflow
Innovate LC-1 wideband system

Estimated 175 WHP or so.
Has run a best of 15.6 in the 1/4 at 87MPH with a semi-crappy tune and street tires and NO driver mod whatsoever. :oops:
Car is amazing on the street, has crazy amounts of torque, sounds awesome, and pulls hard all the way to 7500 RPMs.

Plans for the immediate future are adding a K27 turbocharger which will now be very easy to tune for.
Also working on a new transmission with an OBX limited slip (No more one-tire fires :D )

Current MSQ attached for other 3.0L enthusiasts :roll:
