So I have the 2.5L I4 w/5-speed. I'm at the point where I can't just leave it alone (stock). My cat is bad; a chunk is rattling around in it. Truck is lacking the power it should have to one doing some tune up stuff as well.

Most importantly- get this question outa the way- Aftermarket exhausts. Nothing is sold for the 2.5L, it's all v6 or v8. Does one of the two follow the same route as my 4cyl exhaust does??

 

Open for comments/suggestions/questions/grievances!!




More truck details:
1998 Dakota w/2.5L 4cyl, 5-speed, 2wd
Power nothing, no AC or cruise
Regular cab, short bed, green
56,8XX miles

Stuff just done:
Heatercore and its hoses
Radiator and its hoses
Radiator cap
8 new lifters
Valve cover gasket
Fresh oil change

Things trying to do immediately:
New front tires
New cat converter and cat-back exhaust (all 2.5in)
Spark plugs
Plug wires
Disti cap and rotor

Things I'd like to do:
4.0L tb swap
Re-grind a stock cam
Junk stock intake for pipe/cone filter intake
Fresh speakers and deck

Dreaming here:
Viper wheels
Lowered
Anti-sways
Hurst shifter
Tune? (not sure what's available for these ecu's)

 

some times opening the spark plug gap by .010, if its not all ready over .050. may improve mpg or mph, but may not. i have never had do any thing bad. but check to see that it doesnt hit the piston or valves before useing it. all so if you drive hard go to a plug one heat range colder. .

 

Anyone know if the I4 and V6 Dakotas share the same catback exhausts?


Cummins 4bt swap??? lol
