Decided to go with the evo3 manifold. This is nothing new but decided to share my go at it. I also installed the 1g NA throttle body which I had sent to Steve at throttlebodys.com who did a fantastic job on it, great professional service, and very quick too.
The manifold installed very nicely in place of my OE unit and the mounting bolts are WAY easier to get to on the Evo3 unit........sssoooo much easier. I also ran the harness under the manifold for a cleaner look. To do this, I had to cut back some of the tape/loom and re wrap stratigically to gain length for the TPS pig tail, but that was about it really.
On the manifold, I cut the front 2 mounting lugs off that are meant for the the JDM coil bracket, and the two mounting lugs on the rear side, grinded down those locations, finish sanded the areas, and polished the plenum as a whole. The manifold was filthy to begin with and Im COP now so I had no plans on using a OE coil (if I could ever source/fab a bracket).
Im really happy with the results as far as the fit and the way the install went. I deleted all the EGR nonsense in the process. It was easiest to just leave it all attached at the stock manifold, including the solenoids, for future reference/use. I just had to detach the three color coded vacuum lines at the canister, unplug and unbolt the solenoids from the firewall, and pulled the whole mess out with the stock unit.
Heres some photos of the action. Havent fired it up yet, gonna pop the cams in and roll out tommorow.
