Depending on the heads/block combo you may find that in order to make a cast manifold
work it will take lots of welding/modifying so it is almost easier to get one custom
built to your specs. Wilson is as good as it gets and run around $4500+
If you are running a production style head, i would think of several better ways to
invest your money.

(Apologizing and momentarily hijacking this thread), perhaps a bit more info on intake
manifold "upgrades" could be discussed to clarify:
-"when to" Extrute Hone Stock Intake and Plenium on single-turbo/even-fire builds?
(is higher intake flow rates always desireable? is higher rpm/hp/torque the outcome? is
bigger cam/injectors/turbo`s/heads a requirement? is electric water pump, removal of
AC/accessories also desireable first? is this a "strip" advantage vs "street"?)
-"when, in a build receipe/plan" to consider purchase/custom design" of Intake Manifolds?
(when all weight reduction, turbo engineering, bolt-on mods have been performed?
when planning an non-standard build, as with Twin-Turbos, Odd-fire or V8 implants?
when engineering a2a, radiator, electric fan plumbing?)
-"what potential problems exist
(with regard to throttle bodies? modifying cast intake manifold? hot spots, leaning,
swirling, flooding, adjusting intake flows? improving/degrading detonation?)
Since SyTy intakes are unique to begin with, can satisfactory gains be made (and expected)
in a 11-12 sec ET Build, or is this for extreme performance (mostly)?
....<again, sorry for the disruption, but I found the subject matter interesting>
thanks,
