OK, I want to turbo my SPI, and I think I know a little, but not about tuning. Will I be able to run 5 psi of boost without a tune. I will need to run 93 octane, huh? I will run zetec injectors, my computer should be able to automatically compensate for the added air and injectors, right? Any information will be helpful, thanks.
Give this guy a call. He should be able to help you out. He's a dit pricy from what I hear but like they say "you get what you pay for". I also met Tom and he is prett knowledgable about the focus and lots of people like his turbo kits and work.
If you are on FJ or FF look for a guy name "tinmaddog" His real hame Rusty. He built his own Turbo SPI. Talk to him. As for Tom he builds alot Turbo car but I do not think he has touched a SPI
