Uhh-Ohh…., My Ongoing 914 Build Adventures.... Options

Oh man, I love 914World drama so much. (IMG:style_emoticons/default/wub.gif)

We are all disfunctional friends down here in the Orange Curtain of So Cal. So it looks like thread hikacking, but it's actually harassment on who can get there six conversion running first.

My conversion will be done when it is done. I'm in no race or hurry. That seems like a recipe for disaster to me.

I never dreamed it would take this long, but due to finances, parts, and construction, it still seems a ways off.

I am getting ready to tear the heads off to do a little porting work. So it goes.

You're going backwards.

[AZBanks]

You should be ashamed. Send me your car and $5000 and all will be forgiven.


Then, don't do it again. This is a serious place where we talk about serious topics with serious people, seriously. Frivolity is not to be tolerated.

Again, your honor,... leading.

Teener is correct in his view.


I offer my clear and unabridged apologies to Larmo and all others that I have replied to over the years and particularly for the unabashed hijack of this thread. I should be ashamed.

I am woefully remiss in wasting the valuable time of Monday afternoon World surfers in offering humor, experience and opinion interspersed in my musings on a site that should only be used for singular pointed and focused comment directly addressing the original opening topic of that thread.
(IMG:style_emoticons/default/WTF.gif) was I thinking?



Last post. (....as the British say when facing a potential defeat)

Good!! Take your time and do it right. They are never done. At some point they are just driveable.

WHEN ???

I've been talking to a well respected 911 guy who thinks that 32mm intake ports on my heads are akin to NASCAR restrictor plates.

Is it worth the time and money to open up the heads to 36mm and flow my manifolds? (now shorter ones)

[euro911]

Depends.

How much $ will this cost you?

What's the benefit in HP and torque?

Will you be racing the car in NASCAR events?

[falcor75]

Flow might be important for engines that live at WOT most of the time...like Nascar engines... I think your engine will be more helped with higher airspeed in the inlet ports, helping response and low rpm driveability...

Dont fall into the "Airflow is everything"-hole...

[McMark]

Why don't you install the engine, get it running, and then decide if it doesn't have enough power. You've already got a list of work to do, why add more on speculation? If you wanna try it again later you can pull the motor in an afternoon.

Pros: A Bit More Power
Cons: Spend more money. Spend more time. Risk losing motivation. Risk a neverending cascade of "while you're in there" (twin spark, cam swap, etc)

In my book, port work sounds like an adventure for another day.

[TVRLOTUSTR3]

Depends on cams T & E cams like small ports early S & Solex like large ports.

[Steve]

I ran a stock US 2.7 S motor with Weber's and 1 5/8" headers and was very happy with it. Even the factory RS 2.7 only put out 220 hp and that was with mechanical injection.
If you can change the cams, I would install solex cams. They work the best with carbs. If the motor needed a valve job, then I would look into improving the heads "while your in there". Otherwise the motor stock should run fine and will be a huge difference over stock four.

Anyone that beats on Lawrence needs to come and talk to me. I think he exorcised his demons on to me as I now have two sixer projects going. He's making great progress and gets plenty of fun harassment from his OC 914 friends. We all want him to succeed and get to driving his car again.

Larmo,

I consulted the Porsche 911 Engine God "Bruce Anderson" RIP. According to his bible, (1st,2nd and 3rd edition). He recommends 40 IDA 3C webers, 911 E cams, European Carrera RS pistons and cylinders and increase the ports to 36mm in diameter. Straight 911 2.7 has 32mm ports. Interesting that he says the 911S and Carrera motors had 35mm heads. My motor was a US Carrera motor, so who knows... but it was a fun motor until it started pulling head studs after 150k miles of abuse in my younger years.

Since I have the first, second and third book, your welcome to borrow the 1st or 2nd revision. The performance section of the book is all the same info for 2.7 motors, between the 3 revisions. Great info and every six person should have the book. Bruce is a legend and taught rebuild classes for most of his adult life.

I agree with Mark's comments though. If it's a lot of money and time, I would try the motor the way it is. Not that hard to remove the motor later for improvements or a bigger motor.....

[GeorgeRud]

My 2.7 in the conversion car was put together per Bruce Anderson's book, but eventually pulled a head stud (even though we had used Timeserts in the case). When I had Henry Schmidt at Supertec rebuild the long block with Casesavers and his head studs, he used a S cam profile and his other magic tweaks. 199.5 horsepower at the rear wheels with 40 IDA Webers and stock heat exchangers is an awful lot of fun in a 914-6.

Bruce's recommendations make a great reliable engine, but I think Henry is the man these days!

I would lust to have one of Henry's hot rod engines.

[Larmo63]

I have that Bruce Anderson book.

I can't read, but I do look at the pictures quite a bit.

Because that way he can join Mueller in the "boy is it gonna be a great motor when it finally runs" club? (IMG:style_emoticons/default/wink.gif)

[Larmo63]

Actually, I'm trying to take an intelligent approach to the task I've taken on.

I am in agreement with McMark's comment.

Also, it may be time to just let this thread die.
