I understand this is probably the weakest engine Ford stocks the Focus with. 2.0 liter, and a little weaker than it's 2.1 cousins.
What's the general consenus of this engine overall? Good, ok, shakey, bad?
Looking at a 2003 with one of these and trying to do all the due dilligence I can. :)
Thanks for the valuable feedback.

Well, there are more than a few opinions on this. Get ready for the flaming. I have the SPI engine and most of you at FITF know it will run out very nicely. There are few mods for this engine, but it is the easiest to turbo. It all depends on what your power plans are. If you intend on staying NA, then the ZETEC or the PZEV is your ticket. The SPI has been around for quite some time. It started as the 1.8 tall block in the US, but was used much earlier in the UK in the Escort RS, Fiesta, and other UK spec cars. There is a 20 hp difference between the SPI and the ZETEC, and the lack of a second cam makes you have to develop power other ways. The aftermarket is there, minimally, for the SPI but if you intend on bolt-on performance the ZETEC or PZEV is your ticket.
I have most of the bolt-ons for the SPI, as well as a few I have worked on myself. I can run with the SVT's in NA trim, but she's about maxed out. I have recently turbo'd her, but have yet to tune and run on the dyno. I am runing 10 psi on stock internals, intercooled, with upgraded SCT chip/MAF/injectors. So far no problems. I'm not worried about the engine, it's a proven boost lover. I run my SPI because there's quite a few disbelievers out there in need of a wake-up. The more people who say I can't do it make me more determined to prove them wrong. There's a cop in Indiana who doesn't know what blew past him at over 110 mph. Matter of fact, it was TWO SPI Foci that blew past him at that rate.
Ultimately, it's your decision. If you want to bang your head on the wall trying to figure out a new mod or to try to make something off another car work on yours, the SPI is for you. If you're a sheep, then it's the ZETEC. If you want to be on the leading edge, then it's the PZEV.

The only thing the SPI has going for it is slightly better fuel economy, and possibly reliability due to fewer moving parts.

Sup there, wingnut??
So you have yet to meet the FrankenFord I own. How many SPI's have you really seen? Trust me, the lack of a second cam CAN and IS easily overcome with headwork. If you look at the flow charts, the SPI actually OUTFLOWS the ZETEC headwise. We have larger valves, albeit fewer, and make roughly the same torque off the line. Difference is, the SPI torque band is quite wide and that's what you want anyway. I'm not about to start a flame war, but there are a few Indiana, Ohio, and Michigan guys that have seen mine in action and have a newfound respect for the bastard engine I have.
In short, your retort has no validity. Sorry, but you need to do some research before you spout off one liners.
