LN Engineering IMS Retrofit. First one, Many to go.

Hi guys,

This is my first thread here. I'm a serious 914 guy who owns a Porsche shop near Daytona Beach.

We just purchased a 2002 986 for my wife. Along with the "new" 986 comes the need to complete an IMS bearing replacement.

Here's an overview of my experience today.


This is the victim, I mean patient:

Here's how I supported the engine.

3x3, .125" steel square tube on top of a couple of folded towels.

There is a chain around the tube with two 1100#-rated caribeners hooked to the rear lift-hoop. The nylon strap is a secondary safety.

This worked fine. I'll use it again:

Here's the cam lock in place. Sorry, it's not a great picture. I forgot the crankshaft lock picture.

IMS puller on the factory bearing.

It came out pretty easily, once it started moving...

I thought I took more pictures, but I guess not.

Here's the new bearing in place.


The new clutch arrives tomorrow. The plan is to drive it away in the afternoon.

Stand by.

Very informative...thanks for the posts (and welcome aboard!). Good idea with that 3x3 steel piece for supporting the engine, BTW.

Yea, good write-up. The swap out seems pretty straight forward, looks like you're going to save yourself a couple thousand dollars by doing it yourself. Any plans this weekend?

The old bearing appeared to be in very good condition, but the IMS was filled with oil, so......

It's my wife's car and I own a Porsche shop. The IMS bearing, tools and clutch kit just look like a $1000 charge to the business account to me.

Someone let me know if advertising like this is inappropriate here.


I've decided to offer this service for manual-transmission 986s for $1999, flat rate. That rate includes the LNE bearing.

The Tiptronic will probably me more, but I'll need to do one first. The first one will be $1999 and I'll adjust from there.

996s will also be on the list for $1999 to start.

Clutch and RMS will be extra.

Let me know what you think.

Well, I got the clutch in UPS, but they fumbled the box with the flywheel bolts.

All stop.


Here are pictures of the cam timing verification.

Pull the crankshaft lock out, rotate the engine 720 degrees and reinsert the lock.
