Yes that is correct. It's just a downpipe. No o2 housing with it.

Kracka can you pm me what cobb charged for the labor to do the swap? I'm looking at another major overhaul for my car (while its still in cobbs hands lol) and these are sorta on the list

Cobb didn't do the swaps for us. Kracka and I did the installs ourselves. I helped with his and he helped me with mine. All Cobb did was retune us.

is the work that easy to do for IM/TB? I have the mani on it already as you might be aware

would you guys be up for installing im/tb and an ams turbo kit? :-)

It's not TOO hard to swap them but it did take us like 4 hours to do the IM/TB and probably 4 hours to do the EM. We didn't do it all at once. EM one Saturday and then the IM/TB the following Saturday. My weekend schedule is rough for the next month as I'll be getting ready to move. Kracka might be free. If I can make it, I'll lend a hand.

Since your car will be at Cobb anyways, might be best to let them do it. You'll have to take it in for a retune after the parts are on so it might be worth your time/money to just have them do it while they're in there.

The IM/TB swap was fairly easy, I'd be willing to lend a hand if you decide to do it.

cool, I still have to decide what route I'm going with all this, but I'd let you all know if I wanted some help.

I do also wish you'd done a test that didn't involve the EM as well. Most ppl make big gains from ported exhaust manifolds, and I've seen hit or miss on the IM/TB. Did you all happen to check gains w/o the exhaust?

Kracka

iTrader: (49)

Here's the best I can offer you, before/after just the exhaust manifold, but no tuning. Adding just the manifold did make the car go rich, but it did show some gains in the top end from the additional flow. Tuning is really needed to extract the extra power available from ported manifolds.

Its all good. Eventually I may try IM/TB, I just want to see someone make clear gains from just those parts. Interesting nonetheless

Jake,

If you need an IM core so you can reduce the downtime and not have to pay a core charge, I still have mine. I can sell it to you.

Here are the results of the MIL.SPEC ported IM & TB on a modified X, located in the 1st post.
