Is that the finished connector panel?

there are a lot of big connectors going into there.

Brief update...

I think I now have roughly 99 percent of the parts I need to complete the conversion.

I have the intake pretty well wired up and ready to go, less the intake temp sensor.

I got derailed working on the adapters for the manifold - my little Grizzly G0704 mill was protesting, so I finally completed converting it to belt drive. I also added a giant baldor DC motor (from eBay) and added cheap DRO for each axis. It was too frustrating trying to count rotations of the handles!

I also mostly stripped out the engine compartment and repainted it silver to match the rest of the car.

I should have the adapters done in the next few days, and then it will be on to wiring...

Another update...

As I mentioned previously, most of my time has been spent working on the intake adapters. I now have the first set of three completed, plus two prototypes.

Here's what I have so far:

http://img.tapatalk.com/d/14/08/13/yju6azu4.jpg

I still have to cut out the injector pockets, but otherwise these are ready to go.

Frankly, this took way more time than I anticipated. I hoped to be way past this point by now, so I'm a bit off schedule.

Hopefully I'll have the adapters done by the weekend and can start on the actual installation (meaning wiring, mainly).

I disagree. I have MS2, and have a great idle running 80lb injevtors high-Z.

I have antilag for the turbo, capability to run E85, knock capabilities, lots of open I/O's, boost control, NOS capabilities, etc., to name a few.

MS2 has a good amount of bells and whistles....

I ended up getting the ms3 with the ms3x expansion. Once fueling is worked out, I think I'm going to try a coil-near-plug ignition.

Interesting, I never knew the 3.2 intake could bolt-up to the 2.7. If this works, I may think about this and EFI instead of my good weber carbs to replace the CIS...

Thanks for the updates, and hope to see the details on the adapters.

They definitely work, with a set of adapters djb25 is making, it will bolt up. Turbo Kraft makes a kit if you don't have fabrication skills. You can find their kit here.

I posted pictures on the forum before showing the difference between the intake mounting surface and the heads.

Here is a better explanation for installing a Carrera intake to an earlier engine I posted in the past.

Damion,

I needed to extend the length of the throttle rod between the on-engine console and the throttle body. I used one of these from McMaster. You may need this or another length to extend the rod to the right length. Car was a 911SC 3.0L with an '84-85 Carrera intake. All other parts of the throttle between the pedal and the on-engine console were OEM.

Thanks Brian! Very helpful.

I am planning on posting a parts breakdown once I have everything up and running. No sense in everyone reinventing the wheel.

The Turbo Kraft adapters seem really expensive at $274 for a set of six, especially considering the factory phenolic spacers are $6.50 each. However, I probably have 10-15 hours in machining my aluminum adapters, so $274 isn't bad.

However - the Turbo Kraft adapters are made to adapt to a 32mm intake port - which is a bit smaller than the ports on my 2.7l.

One thing I would do different - I would make my spacers out of phenolic (like Turbo Kraft) or some other insulating material. I really didn't need to make them out of aluminum.

You can tell them your head port size and they can machine them for your specific application. They also come with elongated studs, gaskets, and whatnot. Pricey, but saves me the time of setting down with CAD and hunting down a machine shop, then figuring out whether or not my design worked. Plus, like you said, they are phenolic which will keep intake temps down.

Wow... I didn't realize how long it had been since I updated this thread!

I did go a few months without much progress on the conversion, but I'm putting a bit more time in now over the holidays.

A question for the group - where is the tachometer signal line?

In the factory manual it shows the line as purple and black, but I don't have a wire that color. I have an msd ignition (for now). Before starting the conversion I had the tach signal line from the msd running into a gray wire that was in the previous pertronix ignition plug. The gray wire now doesn't seem to go anywhere...?

Obviously this is my fault - I didn't get a good photo of this connection before disassembly.

Anyone know where I can find the line in the engine compartment?

Thanks for posting this info; I somehow missed this thread. I've been contemplating future CIS replacement and this looks like a good option while retaining a lot of "Porsche content" on the intake.

Yeah, I really like the look of the 3.2l intake. That was a big part of the reason I decided to convert to EFI.

I'll post some updated photos here shortly.

Well, I've made some progress on the conversion over the past few days.

First, I made a new engine compartment component mounting plate out of 1/4" aluminum:

The plate will hold the MSD ignition unit, a Hella fuse block and relay block, the LC-1 wideband controller, and the external voltage regulator.

Here's a shot of the plate with a couple of components:

I also mounted the MS3/MSX unit. I decided to mount the unit under the dash for ease of access and because it seemed safer than mounting under the seat.

http://forums.pelicanparts.com/uploa...1418866464.jpg

I've also run the main wiring harness and the MSX harness. I bought 12' harnesses and they barely made the run to the engine compartment. I'm actually not certain that they will be long enough, which may mean rethinking the mounting location or possibly changing the route I used to run the wiring.

I ran both harnesses without removing any of the wiring, as I'm planning on going with coil-near plug ignition (and who knows what else) once I get the fueling worked out.

Anyway, progress is being made!

More progress...

The throttle linkage is completed and working.

As I mentioned early on, I'm using the throttle body from a 944, mainly because I want to use a throttle position sensor and my 3.2 intake didn't come with a throttle body. I could have used the throttle body from the CIS system, but it doesn't have a provision for a TPS.

Unfortunately, the 944 uses a throttle cable, so the connection wasn't exactly easy to make.

I ended up having to machine a few parts.

First, a new ball end fitting for the throttle rod, made from a socket head bolt:

Next, a spacer to take the place of the extra lever on the throttle body (which I believe was for the cruise control):

Then another spacer to take up the rest of the space previously occupied by the throttle pulley.

I'm not sure what happened with my second photo, but my iPad is refusing to cooperate with an edit.

Here's the photo of the first spacer -

http://forums.pelicanparts.com/uploa...1419056139.jpg

I machined both spacers out of some aluminum rod I had lying around. It was hardly complex machining work, but I have to say - I don't know how I would have managed to get this far without a lathe and mill. There's something to be said for being able to make the parts you need, right when you need them.

Even more progress!

This is a bit of a side project, but I figured "while I was in there" I should do a bit of refinishing.

Here's the intake "before":

http://forums.pelicanparts.com/uploa...1419139767.jpg

And here's the "after":

http://forums.pelicanparts.com/uploa...1419139830.jpg

I refinished the intake with "Cerakote" which is a ceramic-type coating typically used for firearms. I used the "stainless" color.

I also did the fan shroud in the same color. I think I'm going to do the fan in a darker gray color, but I haven't decided yet.

I'm starting with fuel only. Once that is up and running, I'm going to work on ignition. The plan right now is to use the GM "coil near plug" setup, since the Megasquirt can trigger those coils directly.

I could have reduced the number of wires in the harnesses, but I wanted to leave my options open.
