Ok, first let me say i DID do a search, and found lots of related topics, but it seems like there is a lot of other stuff. Basically, i want to switch from a 1.8 to a 2.0 n/t. I don't want to buy a new car. That is the first advice everyone gives(i searched long enough to get a lot of that advice). this was my first car, and i have lots of sentimental attachment to it. So, i know this is possible, but:

1. How hard?
I have pulled and replaced an engine in my Stealth. I assume this would be considerably easier.

2. What is involved?
What else to i need besides engine? Wiring harness? I know i can still use my tranny.

3. Any other considerations for a '90?
I have read in searches that the '90 is different than the other first gen's. What else do i need to consider?

4. What else can i do while the engine is out?
I would love to rebuild it, can i put in high compression pistons(how expensive), and would that make a big difference?

5. How expensive?

Well, i hope i don't get flamed for this. Please help with whatever you can. Thanks a bunch!

so i'm guessing you're thinking about 2.0 n/t engine. It's like pulling any other engine, you did it once you can do it again. You'll need ecu and harness, and engine mounts. How expensive will depend on who does the job and if you wanna upgrade/rebuild the engine.
 
Thanks for the reply. I am a little new to the "wiring harness." Do i have to tear up my interior, or is it something that just plugs in near the engine? Also, can i get high comp. pistons for that engine? Any more info would be great! Thanks!
 
yea you'll need to change the harness under your dashboard too. There are high compression pistons available, skimming the head .020 will raise your compression also. Just remember that with higher compression you won't be able to run high boost if you ever wanted to.

does shaving the head lower my displacement? How much HP will that give me?
no it doesn't, it raises your compression ratio. Hp gains will depend on how you port the head.
