As the four candles slowly burn out...

As the engine on my '88 944na is, I'm afraid, nearing the end of its practical/useful life(i.e. I'm not repairing it every 13 miles), I'm struck with a dilemma: while my car is in great condition, I realize I wouldn't be able to sell it sans engine for what I'd consider a justifiable amount, considering all the money I've put into it. Meanwhile, having a shop replace the engine with another stock 2.5l engine costs a good deal of $, (which I'd do, because the last thing I want to see is my baby in a scrap heap), but then I still have my stock 2.5, but I'm a couple thousand lighter. The question is, what options would I have for doing it myself, and meanwhile adding a little zing to it? I realize the advantages of purchasing a complete 951 or s2, but as aforementioned, I wouldn't be able to sell my car without a good engine, and replacing the engine just to turn around and sell it would set me back considerably.
So what's the feasibility of putting in maybe a 2.8l or 3.0l 16v? What could I upgrade in the existing 2.5l to get noticeable hp gains? Does anyone ever bore a 2.5l to 2.7 or something, or could one bolt 16v heads to a 8v block? I'm open to any [normally aspirated] ideas or suggestions. Thanks alot.

p.s.
(Excuse the quasi-poetic subject: 4 candles=4cylinders, geddit?)

Not likely on all counts. Guess the 88's are starting to wear out. I've gone through one engine myself in my 83.

When was the last time you changed your timing and balance belts and/or cam chain and tensioner?

What's actually wrong with the engine? Unless it really is terminal, most things can be repaired for a realistic cost.
If you want to go faster, but a 951 or 944S2, upgrading yours is not a viable option.

I agree w/britwrench, furthermore even if the problem necessitates the replacement of the block or other major work, I bet you can find a complete engine for a reasonable cost. I don't think trying to upgrade is an option that makes financial sense.

Well, instead of 4 candles, I was going to opt for "4 junkmen of the apocolypse"

I agree with Britwrench as well, what is really wrong withthe engine - a bunch of little things or something major? It may be annoying, but probably not as major as you would think

What consistantly amazes me working on these cars is that if they are maintained and not abused (which your car may have been by a PO) is how good these engines look (internally - bearings intact, rings well within tolorance etc.) after up to 20 years and several hundred thousand miles (have a few NA and turbo customers well over 200K miles on thier cars)

Worst case scenario, I have a complete 944 motor (2.5l 1985.5) available.

Think I had over 200,000 on the original 83 engine. Would have had more but I let the oil cooler seals go a bit too long.

Wow, this is quite encouraging. Mine only has 77k miles and I've had it for a year now (had 54k when I got it), so it appears mine has alot of life left to it. I do take care of what needs to be done, except for the tie rods on a manual car, which cost twice as much as one off of a car w/ PS. I will in time and probably get one at a time til I have em both and then do it.

Cheapest tie rod assemblies I could find were $100/ea. Anybody know of any cheaper place? I have been checking e bay, too

The inner tie rods (the whole shaft really) are expensive. Think these are sold complete with the outer tie rod end. Yes? No?

Yes, they are.....$100/ea. My mechanic has a pair of tie rod assemblies, but for the ps equipped cars. makes all the worse for me (to see and hold it, but can't use it!)

yeah, now you see why I'm upset about the pricing for the tie rod assembly? If this was for ps or non-ps, then it wouldn't bother me so much, but knowing that I have to pay more than twice as much is what depresses me!

Oh well.......I'll keep lookng on e bay for someone that has bought it and doesn't need it. I would think there aren't too many non-ps early 944's on the road, huh? And if so, they should not be 'moving' as well, and thus, be discounted 'somewhere'. I just gotta find out where that 'somewhere' is.....

When I needed an engine, I bought an entire 944 at an auction for $1200, then sold the tranny out of it for $800. I'm keeping some parts for spares, but I'm sure I can get at least another 400 bucks out of it.
Bottom line, When I am done, my engine is free. And yes, it DID get fresh belts!
