IME, I've personally gone to grab 3 at various yards, 2 were on 1990's, 1 was
on a rare 91 10vt. Ditched all 3 since they had cracks on them. FYI, ALL
previous 1989.5< MC cars had the single pc EM installed from the factory.
FYI II, the single pc manifold is NLA from the dealership network (excluding
NOS), all single pc manifolds supercede to the 2pc. Carlsen price is around
800USD complete (3 pc total, + new studs for the head)

Be REALLY careful modifying a k24. The shaft diameter is so small that it
can't support the extra mass of a larger cold side. BTDT on the larger cold
side on a k24. It lasted all of 1 day and broke the shaft. From a flow vs
heat standpoint, I'm not sure the reason for doing a tweeked k24. If you
really do your homework on the k24, flow isn't it's big flaw, heat soaking
from the hot side is.
For the person who is looking at 24psi out of a k24, not a rumor there, it
will fail. For ANYONE to try boost a k24 over 16psi, I'd suggest a Davtron
guage install pre and post IC to measure any predicted success. For those at
any altitude above sealevel, figure 2.1 Pressure Ratio, by 2.3PR you're
looking at iminent failure.
Be smart on the k24 guys, it's design isn't performance, it's design is to
make an I5 feel like a v8. It does that very well. For those looking at
"upgrading" a turbo I5, the minimum is a k26 based turbo. For those with
k24's and tweeked boxes, stage I mods are the most you should consider.
