'92 Plymouth Duster - 2001 Mitsubishi 24v 6G72 swap

Post by shadowplane676 »

First off, Thanks to all that helped me finish this project. All that help was greatly appreciated!

Well, i finally got everything sorted out on my project car. the car is:
1992 plymouth duster 5 speed
Helical LSD
4 puck ceramic clutch and heavy duty PP
2001 Mitsubishi Eclipse GT 24 valve SOHC 6G72 3.0L motor
Megasquirt II, V3.0, 2.88 code
EDIS-6 with GM coilpacks
Headers
hi-flo Catalytic converter
Cold Air Intake


I was able to get this car through emissions on a crude tune (barely passed NOx, but everything else was good), registered, and insured. It also survived a crucible of a 400 mile drive to school on short notice and got ~26mpg on that trip! Its taken me 2.5 years off and on from inception to road legal. on this crude tune i still have to finish, it pulls REALLY HARD and can do a good burnout as well. heres a couple vids to demonstrate the functionality :-D If you want to read about my project, you can view my thread on turbododge.com here: http://www.turbododge.com/forums/f11/f6 ... dates.html Feel free to contact me regarding setup, and tables etc either here, on msefi.com or through turbododge.com.

Burnout!

after an 800 mile highway trip, i was able to tune the car to a nice 27.3mpg. Im going to try to lean it out a little more and see if i cant break 30mpg highway. I hope to go to the dragstrip in a couple days and get the WOT part tuned well (safely AND legally! :) ). still have to work on the rest of the map though. all in all, some 2000 miles later, shes running like a champ, no complaints :yeah!:

well took it to the dragstrip and did about 18 passes between 2 days. best pass of them all:
.781 RT------2.258 60'-----14.960 ET----92.75mph------------lost to a GTP (1.0341 sec)

Unfortunately on the 6th pass on day 2, the unused oil sensor on the filter elbow blew off the block and caused some bottom end damage. Im not sure whats broken yet, main or rod bearings or thrust bearings or what. I may just buy another 3.0 motor for $350, and replace it than try and spend the time and money to fix this one. if anyone has an idea, please let me know. Thanks

Blowout

after rebuilding the bottom end over the summer (2 spun rod bearings) and having a fender-bender which required a replacement of all the front-clip body panels and hood. im still getting 27mpg on the highway. I have since added KYB shocks/struts all around and a 2.5" mandrel-bent exhaust with a hi-flo cat and magnaflo muffler. Changing my shift point to 7000 netted me a consistent 4tenths faster 1/4 mile. im now clocking in at 14.8xx at 94mph at close to 2000ft elevation. i still havent tuned it much so there is still more power and mpg to be had. Im looking at running 0w20 AMSOil soon for the winter and to reduce my oil pressure as im getting close to 60psi at 2900rpms cruise and 80-90psi at WOT near 6000rpm on 5w30 AMSOil. (this might be contributing to the slight rear main seal seepage but who knows...)
