I miss Mike Kojima's writing in my mailbox every month. But MotoIQ is my most-visited website, and has been for about the last 6 years or so, so it's not all bad.
Is that really what a factory 4A-GE head looks like? That casting looks exceptionally poor unless that head has been mishandled.

In reply to oldeskewltoy :

Would be interesting to read a follow up focusing on the modern world of "turbo all the things!"
Of particular interest to me, having a (as far as I know) well ported 1jz head in my Supra. Only point of comparison I have is that it made bout 40whp more than a comparatively stock head on the same dyno, on otherwise stock engines.
