I hear names like Mahle & K.S. batted around by others, but could do with knowing how the cost/performance ratio works out. It it worth getting uprated components just for reliability and future tuning options, or are 'standard' parts as offered by your half-decent rebuilder good enough for most applications bar the out-and-out crazy..
I'm not building a screamer here, though might toy with the idea of forced induction at a later stage, it's gonna be an 8v too, if that counts for much.
Cheers all
