is the SPI the best engine out there? of course not. Compare any of today's engines with a 20 year old design, and modern wins every time.

I am just saying that the SPI is not a dog. It is a strong, reliable engine. Easy to work on (though it rarely needs work) as glassmaker said. great gas milage. What more do you expect out of an econo-box?

In a previous post someone said the auto spi trany is direct bolt up to the zetec. This is true, but you do need the zetec flex plate, as they are not a match. The zetec has a position sensor on it that reads the flexplate. I know because i did the spi to zetec swap in 24 hours and could do it blindfolded. I did a write up of the swap somewhere on ff 1.4 years ago while I did it.

Good to know, mine already had the flex plate with it luckily or I would have ran into problems as well.

I would ask all the people in the onsite broken SPI thread if they considered this engine to be reliable.

Any engine that runs fine for a time and then suddenly drops a valveseat the next time you start it is not reliable. Maybe one doing it yes, but MANY do it, enough to make anyone owning one worry when theirs will, that is absolutely not the definition of reliable.

How much better is the zetec? How about on average close to an additional seventy five to hundred thousand miles more life in many cases. I can't imagine anyone thinking that is a small advantage.

Most likely said from someone who has never owned a SPI.

The engine has one flaw, if rebuild first it would be flawless. How many issues does the zetec have? Not that it isn't reliable either but I've seen issues out the wazoo. Zetec is serious pain in the ass to work on over the spi aswell.

Only 1 flaw, but man is it an expensive one... And It's hard to get motivated to replace the head before it happens.

I feel ya on that. The same reason I never did mine, but I look back now after my zetec swap and the car is just a paper weight currently awaiting yet another engine swap. It would have been so worth it. To still be driving it with no issues.

One preventable problem does not make an engine unreliable. (Ask svt owners about their timing belt)

If a person knows of a preventable problem and chooses not to prevent it, that is the owners fault, not the engines.

No one ever said the valve seats were not a problem. the most definitely are. but they are a preventable problem.

now, you show me how many zetecs are on the road with 200,000-250,000 miles with nothing more than preventative maintenance. exaggeration and hyperbole are not great debate tactics. I think most zetec owners would be happy to get 150,000 miles out of their engines. an SPI with a new head can do that in it's sleep. and many spi's without the new head dropped their valve seat in the 140k-160k range. (though some were much sooner)

if you are going to be a troll, at least be a well informed troll. then someone might actually listen to you.

I'm replacing mine this summer with one from Cylinder Heads International, and I'll be sure to announce it happily somewhere in this SPI section of the forum. Gotta show that there's still some running! It's not the most glamourous way to spend money, but it's a necessity. It shouldn't cost too much anyway. The head itself is $225, and I don't think the labour will be much more than $500.

I've learned my lesson from other SPIs on here, that's for sure. It's tempting to spend money on actual modifications (I've allowed myself Eibach springs/shocks), but it would be downright stupid of me to refuse to do anything to remedy a significant problem that I know all about. I like the SPI anyway! Sounds very unique.

Thank god I only have 20K miles on the car.
