3.8l questions December 30, 2006, 10:57:37 PM I was wondering if a underdrive pulley from a 94-98 3.8l v6 work and fit a 84 cougar with a 3.8l CFI injection system? Besides the stock size injector for this motor will any other size work and like it run? Quote Selected
3.8l questions Reply #1 – December 31, 2006, 01:30:21 AM i tried larger injectors (E0SE) on the 3.8,, too much fuel for the engine to handle,,not saying you wont have a different result.if you work out the Bottom half of the cfi, you could complement some increased air flow (which is the problem). You may gain some horsepower but you still have to get that CFI opened up and port match it to the throttle plates.pully setup? id dono Quote Selected
3.8l questions Reply #2 – December 31, 2006, 11:45:51 AM I can't say for certain...but just by looking at the 94+ pulleys, it doesn't look like they'll work.Now, if you really want underdrive pulleys, you can use the entire accessory bracket setup off of a 94+ Mustang 3.8L. Just be prepared to fabricate A/C and P/S hoses. Larger injectors won't work in theory or in practice, as jcassity confirmed. Quote Selected

I hate to poop in your Cheerios, but there is a reason nobody has built up a CFI 3.8L. The stock ECM doesn't have any aftermarket support, so you can't adjust for larger injectors, timing, A/F ratio, etc. Thus, the need for the standalone ECM. You can port the heads, port the intake, slap on a nice exhaust, turn up the boost...and blow your headgaskets to kingdom-come.It is much easier, both in money and time-wise to either build up a 5.0/5.8...or if you have a hard-on for the 3.8 - Use a late model Mustang version.

Believe me,, im big on the lighter weight V6 engine. User name "spazpuppies" here runs a supercharge v6 in his and is getting ready to install the intended ecm and wiring harness. THats gotta be a quick sucker.DO this........look into the 4.2L crank/rods/pistons and install that into your v6. They are bolt on parts so it make you a cheap stroker kit.i need that camshaft partnumber or source. You need to share that info ********NOW************* or a lot of v6 guys will hunt you down:grinno: Quote Selected

3.8l questions Reply #14 – January 01, 2007, 07:38:28 PM Smells like bullshiznit to me.Ive spent years researching the 3.8L, in every form, and a rebuild kit, a cam and a "stage 2" flywheel will NOT make it run any faster than a 15 second time. Quit the BS, you come here asking a stupid question, then saying your car runs 12-13's? If your car ran that fast, you wouldnt need our help. Have fun trying to turbo a CFI car. Quote Selected
