3.6L 964 motor. Destined to become a 4.0L with 993 RS cams. I am keeping the FI so it is a bit more drivable than the MFI motor I have now.

I actually started this years ago. I bought a 3.6, but it turned out to be unusable. But I had already bought the LN engineering pistons, cylinders, rods and stud kit to make it a 4.0. So now I get to use all that stuff!.

Build off challenge?

That being said Im looking forward to this engine build

4.0 Porsche motor in a 914......

Yes,4.0

Interesting engine build. Are you planning to do the 2017 Build-Off Challenge?

sweet glad you found one!
let me know if you ever need a hand I'm not much of a wrench but I can follow directions


cjl

Dang...that will be a fun motor!

I figured only pineapples got exported from HI

Great find,had the original car suffered from an interior or engine fire?.
What plans do you have for a gearbox,stock or 915 ?,cheers.

The original car suffered an engine fire due to a front end crash.

I plan on using a Boxster 6 speed for a transmission.

How??

If you're going to install factory 993RS cams. .you better buy now às I believe there's only one more in stock at the factory.

Bubble gum and bailing wire.

Seriously, I have been researching this for a while now. I will document it here for everyone to see.




I am not using "Real" 993RS cams. I want to leave them for someone who really needs them for a 993RS. I will be getting aftermarket cams with the same grind.

There is an official contest? I thought it was just for motivation and sharing with the board.

A little gratuitous engine porn:



I started this project years ago, and it got sidetracked by life (layoff from my job) and a bad crankshaft.

Original 4.0 Build Thread

I am glad it is finally going again.

I'm not giving up on my quest for using a Boxster transmission yet , hopefully you'll figure it out before I get back to mine so it'll be easier for me

I just read the thread. I don't qualify. I am only doing a drivetrain replacement.

4.0 ?
I thought of doing this awhile back.

Wow! Porn is apt here; I'd want that pile on the dinner table, so I could look at it while I eat!

Details, I want all the details of what you've figured out. I've heard about these 4 liter monsters and I want to see just what it would take to make one work in a teener.

I'm thinking about a creamsickle six-pack project

........all in for the 4.0 version

Looks fantastic, can't wait to see this come to fruition.

Great project, good luck this time around.

4.0 in 914

You must have alot
Of

Driveing skill to pull that off

An screw the boxter six speed and
How to install ,


You went all out on the engine so

Give me the
Porsche 7 speed stick shift

Boxster 6 speeds are really, really cheap because Boxster motors keep blowing up.

I can't even find a 7 speed for sale. And I don't know if it can be run as mid engine.

Why would you want the 7-speed?
It's only there for mpg, they put a 6-speed in the 'drivers car' 911R, if that tells you something...

Boxster box may be fun, if you can get it to fit. Cable shifter would feel nice too.

Clay what kind of power can you get out of a built 4.0?

325-350?

Please do!! I would be seriously interested in having you do one for me if you can figure out how to do this...the idea of a cable shift 6 speed in Papa Smurf has always intrigued me...

That's pretty good....

I'm just guessing. No real idea.

A stock 964 motor with a free flow exhaust and a chip can make 300HP. I ma hoping for 325, but I have no idea what it will be. Other than more than I have now.

Ugly on the outside but beautiful inside!

It was a tiptronic car. The owner drove it gently and did regular oil changes. So it makes for a great core motor.

Anyone need some stock 964 pistons, cylinders and rods? I have them cheap...

Maybe. Do you also have another case?

Nope. That's why I bought this one.....

Update.. no pictures.

Cases are stripped, including the studs. As soon as I can find time they and the heads are off to the machine shop.

I put all the case studs in my eastwood bolt tumbler. Pulled one out for a sample after and hour. It looks good. Tonight I am going to let them run some more, and pull them tomorrow.

Then I go through the parts boxes, and get all the nuts, bolts and washers and put them in the tumbler.

I also have to get the cam carriers and assorted external engine parts off to Zims to be cleaned.

Looks like the tear down is coming along quick. How many head studs snapped? Looks like at least three on one side...

Mark, after reading your post of 325 -350 hp.
I have a few questions. Being that your exposed to some high end builds. How did you arrive at these numbers? Has the shop built such an animal? If so, what were the injection and exhaust option.

If I recall, a stock 964 3.6 from the factory USA is only rated at something like 270hp.
Asking because I'm inquisitive.
Thanks

My 3.6L is just over 300HP without any modifications to the internals.

Reading all the articles about the Singer 911, I seem to remember those number being mentioned quite a bit.

Im no expert but when you:
Tune the exhaust
Raise the compression
Hot cams
Ditch the cat
Tune the chip
Bigger p&c

325-350 should be a very realistic number.

All, I agree with the above examples of what is needed to achieve those numbers. If I recall, the original poster left some of those critical notes his 4.0 build.
Thanks again for your response.
Enjoy your weekend

Tune the exhaust - Check... I already have the headers .
Hot Cams - not too hot, just the equivalent to factory RS cams.
Ditch the cat - no place to put one on a 914
Tune the chip - already planned....
Bigger p&c - that's covered...

And for future mods I am looking at a hotwire mass airflow sensor conversion.


And for really, really stupid horsepower in a 914, I could spend the 9 grand to put this on:



Adds 100 HP


Not going to happen during this build. I am already getting ambitious enough with what I am doing.

But maybe someday.....

Fun but I can't imagine it would be easy to tune. At least not at home.

I got a peek at the rods and pistons yesterday. Pictures don't do them justice. It's a shame they're going to be inside the engine where you can't see them.

Assuming that the supercharger adds 100 to the already hoped for 300-325, I'm foretelling the project after that. Bigger flares and wider rubber!

Heads, case halfs and one cylinder went to the machine shop today.

About a month before they finish.....
