BASIC 3.6 to old 911 parts list needed.

I have researched many conversion posts and learned quite a bit about whats in store. I'll be installing 95 3.6 into 86 911 tub. I naturally don't want to buy any extras I don't need and thus wonder is anyone can provide BASIC conversion/swap needed parts list. I can easily fabricate dual coil bracket, but know I will need harness adapter. I have solid WEVO mounts so won't need new ones. I can fabricate exhaust components and sheet metal surround. I believe I will need to purchase oil line though. I will need A/C since I am in Tucson so probably need new dual pulley. Anyhow, does anyone have the first hand experience to advise BASIC swap parts list? I plan to buy from Patrick.

Thanks

Having just done a 3.6L swap myself, if you plan to use Patrick, my advice would be to just call them and use them as your resource. If you can get their attention (I had a difficult time doing this even though I bought a bunch of parts from them) they will have most, if not all of your answers. If you call them up or stop by, tell them you have a motor but need all the conversion pieces and want to buy from them, they 'should' provide you with all the support you need. The few times my calls and emails were returned, I found them very knowledgable - it's just a matter of getting their attention as they are seemingly very busy and I'm sure tired of fielding calls from 'information gatherers' who are not spending $$ with them. Hard to blame them for that!

Tom: Most important question at this juncture: Does the 915 transaxle/bellhousing mount to the 993 pattern and can one use the 993 clutch/flywheel assembly?

You can use your 915. You will need a conversion flywheel (Patrick) and possibly some different length studs; the bolt/stud pattern is the same. You can use a 915 clutch, but you may want something stronger.

yes, the 915 bolts to the 993 block, you need a conversion flywheel that bolts to the 993 crank and has the 225mm clutch dimension, you will use a 915 clutch and pp, and all new hardware including the bolts to connect the trans to the block

knee deep in this right now - although I've probably done more than most once I got the engine...

Jeremy -

Congrats on moving forward w/a 3.6L! I am on the home stretch of my own 3.6L install. W/out knowing exactly what you've got coming or what pieces and parts you have, I'll make a quick list of what I had to do to install a '90 3.6L into my '74 911.

In no particular order:

Engine Mounting
- you might need some different length studs to attach the transmission.
- what rear engine mount and cross bar are you using? I used one from a 3.2L, not the 964 and needed different length studs here too.

Fuel Connections
- I ditched the accumulator from my 2.7L CIS motor.
- Supply: The fuel supply on my 3.6L goes to the right front side of the motor. You may need to have a line fabricated to run from there to the rear left of the engine compartment & maybe some metric connector/adapters depending on what you currently have.
- Return: The return should be close location wise. You may need an adapter here too?

Oil
- You may need an oil adapter pipe to connect to the "S" hose.
- If you don't have one, you will need the "?" shaped oil line that goes under the front of the motor and eventually to the thermostat.
- You may want to go with a breather/overflow tank to vent the oil tank instead of dumping all that hot air right into the engine intake.
- The breather hose (engine case breather to oil tank) from my 2.7L fit fine.

Electrical
- I'd highly recommend the kit from Patrick Motorsports. My engine came with 'most' of the kit and it sure would have been easier if it came with all of it!
- Drill a hole in the rear firewall for the elect. harness.
- My car didn't have a computer and my seats are lowered so I had to get creative on how to run the elect. harness and where to mount the DME etc...
- Fabricate a place to mount the coils.
- I removed the rear elect. panel in its entirety. Kind of a pain to work all that out, but make it cleaner and easier in the long run (I hope!).

Other
- Engine sheet metal: you may have to fab a piece in the right rear to fill in where the power steering pump was.
- Block off for the power steering pump.
- I did a single fan belt conversion. Depending on the type of engine mount you use, this may or may not be necessary.
- Exhaust: I am using the Fabspeed w/heat headers and am going to try a MagnaFlow muffler. I had a friend make some pieces for the headers-to-muffler connection (easy enough he didn't charge me) and he'll help w/the tail pipes too which should be straight forward. I don't know about sound levels yet. My fingers are crossed, but I'm prepared to monkey with this for a while. . .
- Accellerator: I spent a bunch of time fabbing a cable and standoff system that attached to the bellcrank on the transmission like the stock '74 system. I am not happy with it for 2 reasons: It's way too stiff w/parasitic drag and the pedal travel is too short. I lengthened the arm on the bellcrank and followed a previously posted 'blueprint' but I'm not happy with it. I just rec'd a 964 throttle cable and am going to give that a try next.
- While you've got access to the engine, you may want to check that the distributor belt looks new, adjust the valves etc...
- You'll need a block off plate for the fan shroud if you remove the heat option.

I'm sure I've left stuff out, but that's what is coming to mind at the moment.
