Intake manifold and turbo set up
« on: Feb 2, 2006, 07:19AM »
im currently rebuilding a KA24E straight out of a stanza, and the intake manifold, has an emission control device on it where there are butterfly valves at the bottom of the intake where it meets the head. at idle they are closed i guess. im trying to decide and figure out how to pull the thing out of there and weld of the holes and port over them to make them smooth. and to plug off the vacuum line. if anybody has experience with this i would like some help.

further more i will post pics and stuff.

and also need advice on what to get machined to how much, and balance the crank as a rotating assembly. im also looking for forged rods. if anyone knows please post. thank you.  :)

JB weld. That's what i did. make sure you clean the holes up well for the JB weld to adhere correctly. Sand smooth with a die grinder.
You will end up with a shit flat spot below 3000rpm, but can be tuned out via remapping the rom in the ecu.

As for your other questions, forged rods are available through different manufacturers, however your question on machining is like asking "how long is a piece of string?". Be more specific.

Crank/rod journals should only be polished, there is typically nothing to machine with them. OEM nissan bearings are the best for rebuilds, as they offer the correct grades of bearing compared to clevite and other manufacturers.
