Basing a focus spi turbo off an escort spi turbo

[crazy_urn]

As donny said, the SPI is a strong motor, if you replace the head to prevent the valve seat drop. I have seen several successful SPI turbo projects. It is not the easiest motor to boost, because you can't just buy a kit and bolt it on like you can with some other motors. but it can and has been done. I have heard that when done correctly the SPI can handle more boost than the zetec because of the different blocks. but that is information I recall reading 7+ years ago, so it may be incorrect.

don't listen to people like zxthrizzle who don't have any idea what they are talking about. they just make blanket generalizations based on a small amount of information.

Do you own research and make your own decisions.

I'm not necessarily worried about the max amount of boost as I never plan on running more than 5psi. I just want to do it cause it's something that isn't usually done.

More power to you. I have more respect for the people who innovate than the people who buy a kit and throw it on.

search for old posts in the spi section. I remember back in the ole days there were a coupe on here. I think the name waterboy rings a bell. He used a turbo from a t-bird, iirc.
