Hi Guys:
This the first time I've tried posting on a site...I just "Discovered" 4Bangers the other day, and read a lot of the information posted. Being new to the Jeep Scene, I have alot of questions.
I'm a recently retired Army Infantry Command Sergeant Major; 24 Years in the Army and 2 in the Marines...all of it as an Infantryman! I grew up with motorcycles (have owned 31 over the years); drag raced an NHRA C/Modified Production (and later D/Modified Production) '55 Chevy, and had a 10.02 '67 Camaro for awhile before I got married in '82. I've had many performance cars on the street; from a '69 Boss 302 (right off the truck in the Spring of '69) to GTOs, Z-28s, Trans-Ams and SS Chevelles.
I've always wanted a Jeep, and last month I bought a '90 Wrangler YJ. A lot of miles but in excellent shape...new Bestop Supertop, 2" Body Lift, New Camouflage Seat Covers, American Racing 15x8 Wheels etc. I went right from buying it directly to Goodyear and put on 31x10.50 15s. It appears to have been well cared for, and when I got it I also got $1450 of recent receipts for maintenance and tuning etc. Runs good and drives straight...had the front end alignment checked when I had the tires installed.
Enough running on...my question is what can I do to make it "Better", specifically in the engine area? I know it's only a 2.5L 4Cylinder and is not a high horsepower or high torque powerplant, but what can be done to "improve" it? I was interested in the following areas: Cold Air Intake; Throttle Body & Spacer; Performance Distributors Firepower Ignition System; Borla Header; Carsound/Magnaflow Hi-Flow Catalytic Converter; and Borla Cat-Back Exhaust System.
Problem: As I look at many and various web-sites and parts distributors, I see that most, if not all parts for 2.5L 4 Cylinder Jeeps are usually '91 - '95, even though they initially say '87-'95. When I call to order a part, I'm being told "That won't work on your Jeep!"
I've been quite impressed with the knowledge that I've seen demonstrated on this site...I seek your advice.
Thanx............John
