I just purchased a 2003.5 Mazdaspeed Protege last week and I've been digging it so far. My brother just purchased a 2005 SRT4 and as you know brothers one of us needs to have the faster sedan. I purchased my Mazdaspeed Protege with a couple modifications from the previous owner. They're as follows:
2.5" custom Apex'i exhaust, AEM intake with K&N filter, relocated MAF sensor, 2.5" Hi'Boost downpipe, Hi'Boost FMIC, Greddy Type-S BOV, stiffer AWR motor mounts, ported and polished head with port matched intake and turbo manifolds, polished valves, FELPRO MLS head gasket, Forged Motorsports wastegate with a stiffer spring suitable for 9PSI.
Where do I go from here? I understand I need to get an air-to-fuel ratio guage and a boost controller. Probably a new intake manifold, etc.?
With these upgrades what would be ''safe'' boost to run? By safe I mean max boost I could run for one or two pulls when my brother and I would race. Yes, I have read this.

My other question is what are the lug/rim/stock tire dimensions?
Oh yeah, here's some photos. There is a bunch of snow up here in North Dakota so these photos aren't exactly up to date.
