Okay so, I've been giving some thought to this...

I think my next mod will be a Ported LIM. How much does this cost, and is it something I could easily do myself? What kind of power gains can be expected from it?

After taking my engine apart last week with my mechanic, I think I can install it myself without much trouble.

Anyone have an old LIM hanging around that they don't want anymore?

PM'd you.

Agrazela has graciously offered to sell me a ported and polished LIM that he will be doing himself. Original LIM is off of a 1995 L36 Bonneville, and is in good shape with no pitting.

So, this thread will be my build documentary I suppose...let'* see how the P&P LIM makes my retirement home sled motivate itself.

Andrew is the man!
One of his P & P LIM'* is working nicely on my car right now.
Really liked the mod. Did not make the car incredibly faster, but it just seems to pull strong and smooth all the way to the top of the range. It also seems to burn a little less gas too. Hard to tell. however, since I have been keeping my foot to the floor a bit much...
Have fun

Glad to hear it, I can't wait to get this done

So it made a noticeable difference through the entire powerband? Cool. Improve low end much? If there'* anything I'd like to boost, it'* low end...but I certainly won't complain about more power no matter where it is.

Low end? Nope. Not really. But keep in mind I have a 98 and 2.84 gears, so I have not much happening down low anyway. But once I am moving, It pulls sooooo nicely. You will love it.

my ported LIM gave me a bit more torque and a smoother running more responsive power .but i see the most difference in second gear at the top end

Uh, bad news bud...after getting all the gunk off this used LIM I've got, I found that the LIM-to-head mating surfaces are, in fact, very badly pitted. I would not use this part. I will be giving it away on the "for sale" forum for someone who wants to practice their own LIM porting.

I could still do you one, but I'd have to get another LIM first. Let me know what you want to do.

My old one is just sitting and collecting dust. If you are interested, let me know.

Sounds like a lead...how'* it look?

Could you post some closeup pictures of the LIM gasket mating surfaces?
