    Is a 2.3 engine terrible? And like very very slow? Is it worth rebuilding the car and keeping the engine or do most guys replace it with a 5.0 or something?

    In stock form, the 2.3 is a slug. 88hp, iirc. I still love them though. You can definitely make them quick. There are aftermarket sources for go-fast parts and they're fun as can be. A buddy has a warmed up 2.3 in an old Ford Courier pick-up and it sounds amazing.

    Having said that, a v8 swap is probably easier and cheaper to build and there is a HUGE aftermarket supply of performance parts available, compared to the 2.3.

    A carbed 5.0 would be easy and cheap. An aftermarket stand-alone efi setup would be easy... and a little more expensive (I believe they start around $800). A donor car would be great for sourcing all the little parts that would otherwise nickel and dime you to death. As a plus, you may be able to part the rest out to help pay for everything.

    The bad news is that v8 parts cars aren't exactly growing on trees. You can still find them, if you're patient enough. If you want to source individual parts, you could come out ahead, where performance is concerned. For instance, mid/late 90's explorers had gt40 heads and intakes. Just throw a performance cam in it and matching valve springs (can't stress enough the need to replace the explorer springs) and you'll have a fun street car. If your fox has a 5 speed (T5), you don't even need to swap in a different transmission. Just note that the 4 cyl t5 isn't as strong... but you can do some minor upgrades to it for very little $. The 2.3 cars came with 7.5 rear end. You will want to upgrade to an 8.8, which are readily available for a couple hundred bucks.

    I v8 swapped my 79 pace car. I have a build thread here. Hope this helps.

    Thank u. I haven’t even driven it yet i saw some vids online and realized how slow it was. I got the car for free tho so i wanna make it a good car that i can use consistently but i definitely need more speed and quickness. Saw this 2.3 on YouTube it sounded like a v8. Thanks for the info!

    You could always do some research of parts needed and build a 2.3 turbo like came in the SVO Mustangs.Im not sure of power level though.A 5.0 conversion is also an option.Its quite involved though.Not only does the engine have to be replaced, but everything else too,like brakes,rear end,some suspension parts.The only reasonable way of doing the 5.0 conversion is by purchasing a wrecked 5.0,that way all parts are available from one car.Just a matter of swapping parts from one car to the other.That being said,the following link will give you tons of options for oem parts from other Ford models.87-93 5.0 Mustangs are non existent at junkyards.You might get lucky on a 94-95 5.0 though. Theyre available sometimes.
