It's on my car now so it's kind of hard to tell from the pics, but it's substantially larger than a 1g manifold.

I have no problem hijacking this thread to talk about your intake manifold so here goes.

When did you switch? Did you notice any immediate improvements? By some awesome chance do you have back to back logs? How is low, mid, and high throttle response? Any idea on the choke point of this manifold from your logs?

I'd love to hear all about it so post anything that you might think would be useful. I have a sick excitement over intake manifolds for no good reason.

I did test it back to back with a 1g head im combination on my gvr4 with a hx40. I didn't get airflow logs because i tune with tunerpro and have never bothered figuring out my lbs/min. I do however keep track of idc's when changing setups, and i tune them to the same afr's, and boost levels. I truthfully didn't see much of a max flow increase, maybe because of the boost i was running(38 psi), but, i did notice a much greater off boost response, quicker spool, and better midrange. It flows enough that my evo 3 falls to about 25 psi at redline, with stock cams. I also checked and the runners seem to line up with the head ports as well as a stock 2g intake.

Quick question fellas since it was not directly described or maybe I missed it,
If I go with the Evo 3 manifold, the 1G throttle body will bolt up right, and I just need to pick up some gaskets?

Thanks, Jayson

Yep

Coolant lines will be angled more but will fit. Make sure to swap over your sensors.

Thank you sir, appreciate it.
