1988 4runner

[SierraNevada4STR]

I need to have 11 posts to start a thread; but I want to make a build thread for my 1st gen 4runner. Freshly rebuilt engine, 22re, and still having what feels like loss of power. Only put about 15,000 miles on this engine since it was rebuilt. Exhaust shop told me my exhaust manifold was cracked, so I'm waiting on my LCE header now. Any other thoughts?
