which engine more reliable to Turbo?

[string]

huh?

Yes? Did you overhear something directed at someone else?

I answered your first self-quote a few posts after it was said.

or did you not realise that i was implying that you are wrong with your assertion that the B18CR's high 8900 rev limit is all in the head?

I didn't assert anything about the capabilities of the B18CR nor what affects it's redline. I said that "B16A 8200 vs B18CR 8900 is in the head" - sure it's a confusing statement, but if you were keen on discussing rather than trying to prove people wrong, you'd have said more than "and the bottom-end". The difference between getting one to the performance of the other is in the head. A B18CR may have fancypants whatever you wants, but it doesn't change the fact that the B16A is only a valve-train upgrade away from it (almost making it an ITR head). A B16A bottom end won't cry at 8900rpm. The B18CR can have fancy parts galore, but it has a 13% longer stroke, it needs better parts to keep it together at the same revs.
