Now about that 2.3L turbo-4 engine: you’re either going to have an easy or difficult time finding parts, depending on what they are. All of your accessory brackets and pumps will bolt on (but make sure all the required threaded holes are in the new block and/or heads, or you’ll be drilling and tapping). Your intake(s), throttle body, injectors, etc. Please see their site or call them for more details. No affiliation but we’ve had very good luck with heads from Clearwater Cylinder Head, and they’re very affordable. That might be a wiser choice for you in the long run, even if they’re a bit more costly. It’s up to you as to which will work for your situation, but fully assembled heads drop right on with no transferring parts from the old ones, save for the rockers and pushrods. Some are sold bare while others are fully assembled. They will appear as stock, and perform as stock, but be brand new with a warranty…and there’s no greater peace of mind than that. But new casting heads, particularly with the aluminum 3.8L V6 heads, are much better because they’re straighter and can be engineered to resolve some factory flow and cooling issues. You can get remanufactured heads, and that’s fine also. Similarly, cylinder heads are available in plentitude and we would highly recommend considering new heads instead of used ones. And as always with a rebuild or remanufactured engine, be sure to insist upon a brand new double-roller timing chain to ensure longevity and consistent performance. Anything over a mild stock cam upgrade can result in timing and fuel delivery issues, so be very careful here. This will ensure that your engine’s computer will perform as expected. Stock-spec camshafts are still available. Just FYI-we aren’t big fans of having the cylinder block sleeved, as that can cause a multitude of issues. If you have any questions or concerns, you can always ask a competent engine builder for advice. 010″ over block can usually be bored out again later on, if need be. It’s not a huge difference in displacement and is safe for cylinder wall thickness. Or, if needed or desired, new pistons are available at. Stock pistons, if still good, can be reused and fitted with slightly larger rings to make up for the larger gap. 020″ over, just enough to clean up the cylinder walls and get them evened out. A standard rebuild will see cylinder bores honed out at. Pre-rebuilt short- or long-blocks can be cost effective, and you usually will get a decent warranty with them as well.įor either situation, you will likely see a very slight bump in overall displacement, which is common. However, you might be under a deadline or you might have a tighter budget, and that’s alright. If you have the time to have the engine removed and rebuilt by a quality machine shop, then by all means, that’s the way to go. The good news is that nearly everything is still available in one form or another for your car’s engine.Īnd therein lies the big question: to rebuild, or to buy an already remanufactured engine? That is usually a question that’s answered by your budget, but that aside, it’s all about convenience and time. (The 2.3L turbo-4 is a little different we’ll discuss that later). Basically, if your engine is tired and needs rebuilt, there should really be no issue finding correctly specced parts for it. The same goes for cylinder heads, camshafts, rockers, distributors, etc. Ford produced so many 3.8L V6 and 5.0L V8 engines that rebuilds and bare blocks are readily available. The good news is that nearly everything is still available in one form or another for your car’s engine, no matter which version or fuel delivery type that you have. You’d just be rebuilding or replacing for stock specs, and no more. In other words, you’re not trying to soup up the car or squeeze every last possible horsepower out of your engine (for that, see the Modifying section). We’re basing this section on the general maintenance of factory performance specs. We’re going to break down this section into two main categories, Mechanical Performance and Visual. It sounds like a daunting task, but restoring your engine to factory (or slightly better) specifications isn’t terribly difficult.
