Good morning, can we pretend for a minute that I was going to do a 914/6 build with a 1974 that is already missing its engine. Further, can we imagine that I would be trying to build a car that would be used rather than showed, and that building a clone and/or a "correct" car is not a goal. The goal would be a well balanced, reliable and sorted out car for backroad touring use.

Does this look like the necessary bits?

-2.7 or 3.0l engine with CIS (have this)
-engine tin
-oil tank
-front oil cooler
-to/from oil cooler lines
-throttle linkage
-fuel pump
-fuel lines
-engine lid latch relocation bits (due to CIS)
-headers
-flywheel
-ECU
-CDI box
-O2 sensor
-Engine mount
-320i front brakes since the extra horsepower probably deserves it

Edit - adding these from Cario and Defianty

muffler
thermostat for the oil cooler
gauges to work with new engine
Filler neck for the oil tank
Oil dipstick
Oil filter console
Six muffler
19mm master cylinder

FI harness (missed that one)

Edit - adding from Lucky9146

Conversion Wiring harness?
914-6 trans mid-plate for throttle or some other contraption, not sure w/FI
Shift Rod modified for headers
Oil cooler thermostat
Oil cooler shroud
Oil Cooler Fans
Oil Fed chain tensioners


Edit - adding from mb911

headers or heat exchangers

Am I missing anything? I did try searching and reading prior discussions.

Thanks!

That's a pretty good start. You might want to consider some light chassis stiffening or reenforcement, 5 lug conversion, upgraded suspension, muffler, thermostat for the oil cooler, gauges to work with new engine, etc. Should be a fun build and car. Of course, as you have seen in my build, rust is the enemy of these cars. Make it structurally sound and build from there. (IMG:style_emoticons/default/beerchug.gif)

Yep that's a good list to start, here's a few extra bits you'll need.

Filler neck for the oil tank
Oil dipstick

Thanks gentlemen.

@Cario, thanks for pointing out the body stiffening. I didn't list that since I had already decided to do it, it has become a SOP on all the builds. I just finished doing that on my 912 project actually. Thanks for that and the other bits.

@defianty, thanks for the response as well and those other bits I missed.

The plan would be to take my time, do what Cario confirmed related to shell stiffening and assemble all of the bits. I have other things to keep me busy so I have the "luxury" of not having to rush.

Make sense? Lots of coaching and experiences in past threads that have been a huge help.

Take a look at my build thread for some ideas. Mine is a '74 with a 3.0 but not CIS.

Horsepower has nothing to do with needing bigger brakes. More effective brakes are needed when mass or velocity or both are increased.

Yes good start.

Probably need:
Conversion Wiring harness?
914-6 trans mid-plate for throttle or some other contraption, not sure w/FI
Shift Rod modified for headers
Oil cooler thermostadt
Oil cooler shroud
Oil Cooler Fans
Oil Fed chain tensioners, if not already there
And all the little stuff you find you need along the way. (IMG:style_emoticons/default/biggrin.gif)


Several of us on here have done conversions so help is available check out my thread but it is not FI http://www.914world.com/bbs2/index.php?showtopic=261197
Best of luck and keep us posted on progress, even small stuff.
It's a journey

Do you have the car yet?

I seem to remember you getting out of a car before you got into it but lost a deposit?
I am old and may have that wrong.

I am in Los Angeles So cal. where are you.

Good list of stuff for a conversation.

Well, the increased horsepower will likely increase my velocity.

Grin.

Hi Bob, you are remembering correctly.

I actually bought a good car from a great seller early this week. It is a ‘74 with a solid body, engine gone already, and driver + paint.

Came with a running 2.7L CIS, and I have since tracked down a 3.0L CIS that is ready to go in after a service.

Given that the car needs an engine anyway, figured now is the time to dig deep and put one of those engines in. Just focusing on the end goal and not getting an interim 4 cylinder in place only to remove it seems ultimately to be a better approach for my specific goals (to be extra clear I am not dogging original engine cars in anyway).

I am in Orange County btw...

Thanks, will add those to my list.

I am planning on starting to acquire the conversion bits while I finish the 912 and sell a couple cars to help fund this.

Not going to rush the build, been there,regretted that.

I have been reading past conversion threads and making notes, it’s been a big help.

Thanks!

If you're sticking with the CIS and want O2 sensor, you'll need 1980 or newer CIS controls.
That was the first year that used an O2 sensor to feedback mixture control

Wondering about skipping the heat exchangers since I live in SoCal....

Any been there / skipped those thoughts?

Ah, my systems pre-date that so I can drop that from the list unless it is a worthwhile upgrade.

Do the later CIS systems with the O2 sensor work a meaningful amount better?

Thanks!

You are on your way. Great guys that will help you out if you need and give great advice more than any other Porsche site I have found.

2.7 S is nice but the 3.0 are a super choice for engine, just stronger with better elements. I went with a later 3.0 and put 3.2 hears with the bigger vales different cams and 46PMOs

I had a 74 ( factory Black car) with a 3.0 CIS conversation back in early 80 when not that many people knew what to do. Stock body with Mahle Gas Burner Sports Wheels for Porsche 911 914- Now $4900.


Blue is a great color. Are you going to keep it a stock body?

Hi Bob. Everyone here as been super helpful, I feel very fortunate to have found you all.

Leaning towards 3.0l as well...

Did you like the CIS? I know most like the sound / looks of the PMO carbs but I don't think I really want to spend the money those at this point when I have a happy CIS system. The car will see altitude changes as well.

I am currently planning on keeping t a stock narrow body car.

CIS, in Good working condition, makes for a nice driver. It’s not so good if you want to hot rod the engine.
If you have access to a 3.0, it’s a great engine. Just about bulitproof. The single turbo 962 at our shop uses a 3.0 block for the base of the engine. It was dyno’d at 780hp.
