Installing a 3.2 into a 73

[JeremyD]

Similar list I'm doing with the 3.6

Fuel lines? I've rebuilt mine (amazon hose) also got the alternator and starter rebuilt while the engine if out. Fuel injectors are off to be cleaned. Finished adjusting the valves last night. Powdercoating stuff sent out this morning.

New exhaust and intake seals.

New o rings for the oil pressure and oil temp switch and breather gasket -

Plugs will come out and be cleaned and replaced.

How about oil cross over line (early oil line) that goes under the flywheel? How about the S line back to the tank (I got mine fire sleeved)

Monoballs on the rear trailing arms? Sound Pad? Fuel filter/etc?

I'm also replacing two of the gaskets for the knock sensors in the engine shroud.

Definitely ref sensors and cht sensors on the carreras.

Just finished my conversion although it was for a 66. Will need to make up a plate to mount the efi under seat. I also had to modify the seat frame slightly so it would clear it.

I ran the loom down the tunnel.

I'd also consider upgrading the front calipers.

You might need some bits for the oil tank as well.

Terry, I did a lot of research on the front cooler install. I decided to run braided hose throughout the tunnel? Easy job actually. Might put a fan in later. Use the elephant cooler. Best option in long run.

Good luck

Very slow progress. Sort of went wild with prepping the motor, ended up pulling all the exhaust studs and installing new ones, in addition to everything else on the list.

[Shaun @ Tru6]

A little bit of progress on the custom high clearance oil lines.

[Shaun @ Tru6]

a little more progress.

One of Damon's (Series900) fiberglass left side heat block off. Excellent fit on this piece.





Test fitting the 915 cut for sensors (Bosch BMW for 1/3 the price).





Front and Rear factory metal lines running through the center tunnel flared with fittings.







Hanging the oil lines. Rivnut tool is a necessity in anyone's box. Simply amazing.

Got to admit I didn't read every word, but I don't recall seeing "enjoying an adult beverage" anywhere on the punch list...
In all seriousness, no matter how hard we try to prepare for any and all circumstances, be ready to roll with the punches and re-group as necessary.

Nice job Shaun! I guess you dont need the riv nuts that are still sitting on my desk?

[Shaun @ Tru6]

Thanks Mark. Tonight was fun with Al sheet night.

First made the fuel filter holder. It's not straight but the holes are 6mm, so if I just run an 8-10 bit through them, it would sit perfectly in line with the electrical panel made by Ed Sully.







Mounting the fuel pump proved a little more challenging and rewarding. Second iteration of the top rubber mount holder.




installed with a slight bend to better meet the mount.








Can't wait to get the fuel lines fully spec'd on Wednesday and then built by member BoxsterGT.

a wheat beer would be great right about now Charles. This project is truly death by a thousand cuts. Adding to the list are:
install new clutch cable
install new speedometer cable
cut off rear fuel pump mount which is perfectly in the way of running the motronic wiring harness. this should be fun.

[Charles Freeborn]

You certainly deserve a frosty one! I'm following your project with interest. My local P-rod shop recommends a similar swap when my 2.7 gives up the ghost.

[Tspringer]

I sure hope yours works out better than mine so far. Cannot get the 3.2 to idle correctly, its baffling.


Are you changing the oil tank? On my '73 the oil tank is apparently different than on the later cars and I suspect that my poor idling has something to do with this as the car idles fine when the oil tank lid is removed.

[Shaun @ Tru6]

Hi Terry, yes, I'm using the complete oil system from the 86 I parted out, just POR15'd the tank tonight. I suspect it has to do with the small air line that runs off the back of the main oil inlet. Carrera tanks can be had for under $100, and they have better baffling than the one in your 73.

[Shaun @ Tru6]

Long day today, got the motor, wiring and DME in along with oil line stuff, etc. First, the fuel pump I bought off a fellow Pelican turned out to be junk. Putting the original one in from my 86, it hums nicely and fuel is going back just fine. The fuel system is the best part. Turn the key, it cranks over wonderfully. and over and over, with no hope of starting. as it is the end of the day, we didn't do much in the way of troubleshooting. Swapped speed sensors. Coil has voltage and some of the terminals have voltage on the to-the-motor 14 pin plug. Too wasted to write values down but will in troubleshooting later this week.

Could it be the anti-theft system wire, a remnant of the 86 harness? there is one wire we both left alone and ran hot. no change.

My hope was running today, driving next weekend. Good to have dreams I guess.

[dezzmo]

We covered practically every item on that car today Shaun, I still can't think of what would stop it from firing up. We should have tried my DME in your car just for the hell of it. Maybe next weekend if you still don't get it running by then?

[Shaun @ Tru6]

Tim, thanks so much again for coming up today! I'm pretty sure it's the alarm. Have to check for spark tomorrow and the basics, but it is probably just that circuit inside the relay that needs to be closed.

What are these electrical symbols?

[70S Targa Guy]

I like that setup! Project looks really sweet Shaun!

I have a 1972, with 3.2 engine, chip, stainless heat exchangers, short gears. It impressive. Solid as a rock, light weight, reliable. Its the best of both worlds. It is very quick!
I can't answer any technical questions, because I didn't build it. But it was done right by Rothsport, Jeff Gamroth, Oregon. With trans freshening, to total conversion was $18,000, not counting engine cost, in 2004.

Gorgeous car!

Thank you, but that should go to Pelican Ed Sully. he did a really nice job on the panel. I made a square.

And the car now runs! I shorted terminals 30 and 87 on the DME relay and it works like a charm, engine is smooth and runs like I've been driving it all year.

now it's all down to details, and there are a ton of them, to get this car on the road.
