all you guys that have internal mods done to your motor, how do you work it out. do you buy a product and install it as soon as you get it, or do you wait till you have everything purchased and do it all at once? i need my car for work/school, so having no motor in it for some time will suck for me. so was thinking, what if i buy a used motor and have that layin around so parts can be put in. i'm just dont quite got the knowledge to be able to spot out a dead motor. thanks
Nope, it ain't stock.
Having a spare motor would definately be the best idea (I ended up just buying another car to drive around though
)
Buy a motor from a car that the insurance company totalled, chances are it ran fine, the body was just too messed up.
Installing parts one at a time just doesn't work out for anything below the head. For instance, you want to have the decks surfaced if you're putting in an aftermarket head gasket (engine has to come out). For new pistons, you should have the cylinders honed (engine has to come out).
However, because you have a DOHC, you can swap cams over the weekend if you want. If you've got some extra guts, you could port-match your head with it still attached. You could put in new headstuds in an hour or so.
New valves? Head has to come off, and the seats should be machined.
It all depends what you want to do...

I have to agree with OHV on that, Good points all, I personaly Like to buy it all at once to do at same time. Now saying that,I have recntly went away from that, My GF 98 Cav has a 2.2 motor, I planned on Buying her a rebuilt 2.4 from JBP this time instead of me Building it, But there are still things that you have to do before you get started. Like ignition upgrade MSD DIS 2, Header/Exhaust, intake and all the items your gonna need to get the swap done..
But the ultimate thing to do would defiantley buy a running engine and build that instead of piecing it. Finding a running motor is not difficult now days, For most salvage yards will run the engine for you, That is if they are a reputable Salvage yard. Look around and check them out totaly. If not usually rule of thumb is to find a car that is smashed heavly in the rear, Then you have a better shot at getting a running engine.
JBP Built 2.4
250HP
230FT
Dont race
But dont push it
It really is all up to the person and what you can afford. Me personally, I don't know when another part will ever come in so I just have it installed instead of saving the part for months or years. Example: I wanted to buy a new head and work on a block and have it installed. I bought the head and installed it. Some said "why install it when your getting the block?". Well money issues can always come up so I'd rather enjoy my head instead of it sitting around my house.
The best thing would have a spare block to work on to do the bottom end and buy a built head (in my opinion).
It really doesn't matter how you do it, as long as you do it.

well good lookin out fellows. yea, the good thing is my car will finally be paid off by the end of this year. (ohh yeah). i have planned to buy a spare car just to do running around in, while my z is having its transformation done. that's good points you guys said and the only way i can have all this done is to buy parts and have them "layin" around. like you said, just work from the bottom up. well, i guess i'll get started on finding a motor, i hope to have this all completed by next summer. thanks again, kc
Nope, it ain't stock.
i thought about this too, cause i don't know nearly anything about how an engine works, but i am willing to learn more. i was thinking of buying another 2200 engine and beefing it up over the winter along with fuel system and ignition and into the spring then swap it out for my other engine. then i can save up for a really nice turbo set-up and in about 2 years i think i could have a really nice turbo 2.2

well, I got lucky, I had an engine given to me and I did most of my mock up work esp for the 086 head swap on that block. Everything listed in my profile took about a week to compile and another week to plan and put it all together...
well... as long as the block isn't cracked on the motor you're looking at, you're good to go... everything else can be replaced (more or less).
What I would do if you plan on building up a motor seperate from what's in your car:
1) Acquire motor
2) Build up some dough
3) Tear the sonofa*** apart (well, all the accessories, oil pan, head)
4) Decide based on the condition of your pistons, crank, cam(s), bearings what needs to be replaced
5) Cover/Seal the engine (saran wrap 'press-n-seal' works well)
6) Buy replacement parts
7) Parts come in
8) Open up engine, rip out the guts, rebuild it (making sure to use plenty of assembly lube when neccessary)
Why do you need to re-seal the engine after you take off the oil pan and head?
A: Exposure to air can cause metal to corrode, and due to the fact that you already drained the oil, there is no protective coating on the bare metal
I would recommend buying a head that's already been built (port/polish, etc) unless you know of a good place around where you live that can do the work reasonably for you.
At the very least, get better connecting rods, replace the piston rings (re-hone the cylinders), bearings, cams and rockers, and oil pump
