    Penny for your thoughts....

    Hi All; I hope everyone is well. Clyde and Phil - looks like you must be in seventh heaven! Also, good luck to the runners in a fortnight. Enjoy your taper time!

    I haven't posted hear all that often since joining but I do take a peek quite regularly, and I should put something to rest right now - no doubt about it, I am the dullest crayon in the box with respect to technical nous associated with early 911's. Learning slowly, but a looooong way to go.

    That stated, here is where I am at: Shortly I am hoping to have accumulated a modest sum of money that I have been planning on putting into my 69S. The idea is to do the engine work that I knew the car required when I bought it about a year ago. It's leaking oil significantly, has some bearing noise, timing chains are worn (I've replaced the tensioners already), probably requires having the fuel pump recalibrated etc, and it would be great if cold starting was no longer an issue. I plan on having it pulled out and opened.

    Being a 2.0S, bringing it back to spec won't make it the quickest car going around by any stretch of the imagination, but I'm not particularly concerned with this. My daily driver for the past four years has been a WRX and whilst it is a better car than I'll ever be a driver, I find it a bit sterile and unless I want to risk my license (Idon't), it's hard to enjoy the car in the way it is meant to be enjoyed......(or maybe I'm just not trying hard enough!) But the Porsche, even in it's current state, is different. As you already know, and I have now discovered, these cars have real character. I don't need to be keeping up with WRX's or HSV's being driven hard to be having entirely enough fun, and I'm not interested in "tracking" it (don't have the skill or the finances to risk it). I took it out past Healesville last Saturday afternoon (before the rain of Flemmington on the Sunday - nice to have met some of you and great cars....I felt for you in the rain) and had a wonderful time. Such days epitomize the experiences I want with the car.

    But....I don't want to be pulling the engine out regularly and I don't want to be missing all the obvious "little things to take care of" because of ignorance. The old "you don't know what you don't know until you know it" seems apt right now. Are there some aspects of the rebuild I really should be taking care of that are cost effective and whilst not straying too far from original, will make a difference in terms of reliability and usability?

    Any feedback would be great. Thanks.....

    Have you done a leak down test Craig and good to meet you last Sunday even if it was in the wet.

    Heaven can't be as good as Sonoma!!!!

      a good place to start would be bruce anderson's 911 book and wayne dempsey's 911 engine book. many good ideas for performance/reliability upgrades. i don't think however that you will find a definitive list as every mechanic i spoken to seems to have their own likes/dislikes.

      some ideas for your 2.0S in no part'r order:

      1. slight capacity increase - 2.2?
      2. upgrade the ignition system
      3. ditch the points
      4. slight comp ratio increase

      another option would be store your (presumably numbers matching 2.0 engine) and fit a larger motor (eg 2.7). you will have a very fun/fast/drivable (torquey) car and preserve the value in the "matching numbers" stakes should you ever want to sell.

      if you wanted to conserve the revvy/short stroke nature of the car - then fit 2.7 barrels and pistons and you will end up with a 2.5 litre gem of an engine.

        Hi

        My car currently has about 70K miles on the odo (of which I can account for 15K). I have found the standard 2.0S engine to be very reliable and can honestly say it has never let me down, and I drive the car regularly. To my knowledge the car has not had any major mechanical work.

        My advice would be to keep the engine standard. If the rebuild is done properly it should last for a very long time, and it will still be a blast to drive.

        With regard to cold starting. My car has a modified system via a push button on the right hand lower dash end which activates a solenoid on top of the fuel filter and squirts fuel into the top of the intake stacks. This system works well once you get the hang of it, but it is not metered in any way except by how long you hold the button in, so you need to make sure you only give it a couple seconds at the most.

        Regards

          It looks like you are happy with the cars performance and just want to rebuild it taking into account the modifications that will increase its reliability and engine life.

          As per Ryans comment the book How To Modify and Rebuild Porsche 911 Engines 1965-1989 by Wayne Dempsey has lots of great text and colour photos and details a great deal of what can be done to these engines.

          Its a good starting point and will help you with a bit of technical knowledge for when you start talking with engine rebuilders.

          Good luck!

            A 2.0S is becoming a most collectable car in the early 901 range.
            I believe the engine should't be stufffed about with just to get more HP (factory quote approx 165bhp from memory)
            In the first instance you should talk to those mechanics who specialise in these early cars - three of whom are club sponsors.
            Mike and Lisa at Spyder (Cheltenham), Phil Hearns at Auto Coupe (Eltham) and Bob Whyms (Sydney).
            Even though Mike and Lisa are out of action for the next three months, I'm sure that they will offer advice or at least tell you where to go!!
            Also, I recommend George Cairns (Ferntree Gully) who I have known for 26 years and who knows thes cars inside-out. He has a great reputation in setting up thhese cars for racing and rallying (his cars gained first 3 places at recent Targa Tassie - not sure which class)
            My advice, keep it simple and as original as possible - both engine and body - you'll have a more reliable car that you can keep on the road to enjoy.

              Thanks for the food-for-thought All. I'm going to do some reading - I now have my hands on WD's book and I'll keep you posted.

              I share the sentiment expressed by several of you that preserving the design intent of these cars is to be taken somewhat seriously, and I don't intend on being too unsympathetic to how my car started out (granted it's been color changed and converted before I got it...but still). That being said, I'm not building a concourse car here. See you on the road one day soon....

                Phil's doing a top end rebuild on my 2.0 - the engine is still apart and looking pristine at his shop - feel free to travel there and take a look if its convenient for you and have a chat with him about it.
