My Kia Spectra5 Turbo Project

This site is a collection of documents, links and pictures on what I've used on my Kia Spectra 5 turbo project. Use as you see fit, but I take no responsibility in your own project or how you use the information in and on these pages. You've been warned !!! 

Highest output so far has been 257whp.

I started this little endeavor in the summer of 2007 and have been slowly chugging along, getting pieces as I could afford or find. Turbo is a Garrett TB0357, new in the box. Its both oil and water cooled. It was originally used as a factory upgrade/replacment for a late '80s or early 90s Saab 900/9000. Comes with journal bearings and has a factory setting of 7psi.

Manifold was custom made at Speedfactory, in University Place, Washington, by Ricky Eickert. He created it from schedule 10 stainless steel pipe and it incorparates a full 4" collector.

Two gauges are installed in the A pillar. An AEM Digital A/F gauge along with an Autometer electronic boost gauge with auto zero function on start. I was considering an exhaust temp, but it would have been to crowded with the three gauges.
