A lot of people dont know that the SPI (CVH) was a factory turbo motor in the UK Escort RS and turbo Escort GT/EXP in the US. Only thing that has changed is compression ratio and displacment.I was gonna say around 7psi off the top of my head, cause stock internals on the foci's SPI are well, ok I'm gonna say it......weak
hey now you're exempt from this lol....... I KNOW your SPI isn't weak at all  hey, WTH, mine works great for me too..... [thumb]IDK why so many people think just because the spi has low power stock, that means the internals are weak?[dunno]
Jeff knows whats up.
