so i have a 01' mustang and i have 130,000 miles on it. i want to start doing engine modifications but i dont want the engine to go kaboom if i do too much to it. i have a few questions that need to be answered. where can i get a rebuild kit at? and how much would it cost. also i am wanting to bore my engine to a 4.2L and i was wandering how much that costs. can someone of you people help me out please it would be greatly appreciated.
You can change your set up to a 4.2 , here's how ,get a 4.2 crank get a set of Scat 6.125 rods , custom Wiseco pistons (All this is available from Tom Yentzer at Supersix motorsports .) with ported heads and a a nice cam you will feel the difference .

alright so this might sound stupid because im engine illiterate. but when you do that you are basically rebuilding the engine correct? and will that make the engine last longer like if you went out and bought a new engine. please dont make fun of me this is why im on here so i can learn about this stuff. so just let me know
There are still a few more parts needed but Gary covered the biggies. There are still 4 sets of bearings, oil pump, head bolts, probably larger injectors, and a ton of gaskets.
We had Tom Y at Supersix build my Son's motor because we didn't have the knowledge at the time either. We are glad we did because there are many factors involved in building the perfect motor. I'm going through that right now with a rebuild on the '02, but this time we are doing it with the expertise of a close friend, not Delk.......

Your first step should be buying a chilton's or haynes repair manual, and read through the engine rebuilding section. That will be a good start (or go to the library if you want to keep costs down, they run around $20) The second step as far as educating yourself, if you plan on building a "stroker" motor, is buying a performance engine building manual, it will have tricks and tips that a standard rebuild manual won't. Most of engine rebuilding is easy stuff, just following sequences and instructions will make it go smooth. If you take your time and are methodical about it, you will probably get a decent build. I have built three motors in my garrage as a shadetree mechanic, and all of them ran great. One of them was a stroker 393 windsor for an old cougar I had. It was a beast.
It will be fun, and you will save some dough doin it yourself. Don't cut any corners, and if you get frustrated, take a break and start fresh when your frustration has subsided. Nothing worse than trying to "force" something and it breaks, then you have a new problem stacked on your old one.
good luck. have fun.
From what I have read I sounds to me like you have no clue as how to properly build an engine . To me it is cheaper in the long run to find a good engine builder and I mean engine builder , not assembler
because as mentioned above the specs are different depending on what your plans are to make hosepower . For example Ring gap for an N/A engine or nitrous is different from the ring gap on a F/I engine . My advice is to find a good engine builder and talk to him on what you want to do with this engine.

Every "expert" has a first. Dont discourage him from trying. Probably the worst that could happen is he learns a bunch of mechanical skills, and has a mediocre engine. The best.... his build turns out decent. Torque wrenches aren't hard to use, and if you have the time and resourses (I.E. another car to drive while you build) then going slow and methodical can yeild a good build. The mentality of sending it to the experts EVERY TIME is why there are so many mecanicaly brain dead folks driving souped up cars. Guys that don't even know the specs of their cam's, they can just tell you they have em. I hate those guys.
I'm building my motor for myself... I have no motor building experience so lets see how it goes. Not something I would call "hard" just something you need to make sure your precise with.

We are not discouraging him, we are simply telling him that building a motor for the first time is complicated. Even if he has another car to drive, putting it together, starting it up, and having it blow up on him is an expensive lesson to learn considering most people on here do not have money to start over again. Can you really explain to him and then have it done properly the tolerances? Piston to wall clearances? How about ring gap on a forced induction over an N/A application? Valve lash?
The first motor build should be done with guidance of an experienced builder. Who really wants a rebuilt mediocre engine?????

No, I can't guide him through EVERY step, but chiltons can. I have rebuilt 4 engines now, and the only "training" I had was a high school motor shop class. None of them have "blown" up on me. None of them ever failed due to a mistake I made. I do not claim to be a magic man. I just simply followed directions. They are clearly printed in several manuals. What the heck do you think the "experts" use when they have a question? Do they ask you? prbly not. They use the manual.
By your responce, you seem like a very fearfull person, and I would wager that you have never ACTUALLY tried to build anything on your own without help. That is a sad state of affairs. Things do actually do work out most of the time when people take the initaitave. Mechanics arent gods. They are just people who decided to try. That is all.
