Most of us just don't want to have to do what we see as unnecessary work on our cars. We'd rather be driving than changing (or worrying about) our timing belts. Another pain is that the interval between replacements is so short.
I just sold a LandCruiser with 175,000+ miles. The first question the guy asked was "when did you last change the timing belt". He was dismayed when I said never and then overjoyed to hear that it had a chain.

If you modified the car to use a wider timing belt you could probably find one that will go 60-90k miles between changes.

Yeah, that's a full set of new rollers. If I need another balance belt, that's fine.
The starter I'd replace if it's really going bad, but it'll need a totally different one when it's time to drop an LS engine in there, so unless it's going to fail in the next couple of months, then it might not be worth the effort.
Anything else you see in there that looks like a good idea, just let me know. I'm happy to shell out a little cash when I know I'm getting good work.
Say, if I set up a weekend appointment to drive out to Renegade Hybrids, do a shop tour, get their recommendations, etc, would you interested in going along?

as for the starter, it really isn't difficult; i took out my old one and had the new one in one evening in a half hour...its only 2 big bolts and 2 electrical terminals to deal with, just need to lift the car sufficiently to get back there.

well theyre in Vegas so thatd be a bit of a trip that would take some planning so maybe...it would be great to see all their stuff though. maybe over spring break or something? (end of march)

Let's see how it turns over once the timing's right. It started a lot easier when the timing wasn't off. But if it still seems dicey, then that's doable, too.
Thanks for all your help.

yea, im going to swap out all the rollers, check and set the cam timing and tension it, then do the balance belt sprockets (if you have them) and tension the BS belt properly, the run it and make sure all is well before putting the belt covers back on..

Lorax said,
The LS1 doesn't qualify as a performance engine? Does it have a belt or chain? I assume a chain but honestly do not know.
That's just never going to be the case on any erformance engine, I'm sure you know that.

OK, I'm back.....
Ryan, I've been reading your posts, and it sounds like you should buy a kit car...An Atom or something of the like. If you want to fab an entire new front end for the 944, you might as well just build a new car, from the ground up.
I like to tinker with my car. Thats part of the reason I bought a 944. But, I also like to DRIVE my car. I don't want to weld in a new tube frame. I don't want to cut, and grind and weld much of anything on my car. I agree that LSx is the "boring" choice, but thats why I think it works so well. The install is fun, and not a quick "weekend" job, but when its over I get to show my 0-60 in 4sec 944, not park it and show people my perfect tube frame.
I can run a bead we well as anyone else, but if you want to see my welding skills, I'll make you a table...and I'll deliver it in my 190mph 944 lol.
(I'm not attacking your ideas in any way. You seem like you could build one hell of a car. I just think you're missing our point with the LSx swap.)

In engineering, we have a principle we like to pay attention to when designing systems. It's referred as "accidental complexity" vs. "inherent complexity".
(The latter is technically called "Kolmogorov complexity", and refers to the maximum compressibility of the information that specifies a system.)
Accidental complexity is complexity introduced by how you operate on a system. One strives to remove it in any situation.
Inherent complexity is how complicated the problem actually is. It can never be removed and still solve the problem the system has to solve.
The idea is that you remove accidental complexity wherever possible, and put your efforts into producing the best results by saving your attention for dealing with inherent complexity.
In other words, you don't do something unique and reinvent the wheel to show how clever you are, you put that cleverness into getting the best results out of the known efficient solution.
