  1. 1 careful owner... Big box of parts A bit of elbow grease should fix this... It's not like the alternator and fan are important anyway... Special order banana shaped stud Looks like the bottom of an old coffee pot... Presto! Stage 1 cleaning completed... That doesn't look like loctite 574...
  2. Since ITBs are the new black (Pork Chops?) and we have quite a few projects done\going on the forum I`ve realized that there are people who don`t really understand the concept of ITB on aircooled 911s. I`m not going to dig into the physics and aero\thermodynamics but will try to explain what is it, what the typical kit should be like and how hard will it be to setup. With the brands and rough prices. Well, let`s start with the terms. ITB - individual (independent) throttle bodies. In our case there are 6. Intake manifolds (runners) - the peace of metal that attaches the ITBs to the intake channels on engine heads. There are roughly two, one per each side. EFI - Electronic fuel injection. ECU - electronic control unit (a brain) the thing which tells the injectors when and how much fuel do give and igniters to spark. Basically what you need in the kit for a complete install: ITBs Big Brands are PMO - http://www.pmocarb.com/products.htm Hargett Precision - http://hargettprecision.com/index.php/porsche-products/porsche-throttle-bodies/porsche-itb-s.html Jenvey - http://www.jenvey.co.uk/products2/throttle-body-kits/porsche-2-bolt-large-port-sf-taper-throttle-body-kit-ckpeo2 AT Power - https://www.atpower.com/products/porsche-911-45mm Borla Induction https://www.borlainduction.com/3003-series.html Rothsport Racing http://www.rothsport.com/Products/Engine/Fuel-Injection-Systems/FI-Systems.htm Smaller brands are X-Factory - http://www.x-faktory.com/store/p3/EFI_Kit_S3-EFI-001_.html ClosedCourseMotorsport - http://closedcoursemotorsport.com/triumph-itb-setup-for-911-aircooled-engines/ Racehead - http://racehead.com.au/products-page/throttle-body-kits/porsche-bolt-on-itb-kit/ And complete DIY setup is based on Triumph Motorcycles ITBs (we are lucky they have 3 cylinders). I`ve seen so far setups based on Triumph Daytona 955 and 675R bikes. They are not that expensive, from 100 to 200AUD for a set (we need two sets). Last two companies mentioned in the list utilize 955s TBs in their kits. Pretty much all above don`t have EVERYTHING to complete the kit but it is due to many variations of the execution of the setup. Most of them include ITBs, intake runners\adapters\manifolds, Linkage, fuel rails and airhorns. The rest like X-Factory and CCM have a bit more than that but again, you should add some to their kits as well. Intake manifolds... and adaptors. As I mentioned before most of the setups have them which makes everything easier. But if you are going hardcore and want to build a kit yourself I`d recommend to use Triumph 955 TBs since you can order a set of adapters\manifolds for them. Look at X-Factory and ClosedCourseMotorsport products. But if you are familiar with TIG welding then you have no limits. Say I had to send my 675R TBs with manifolds to Eastern Europe to Soara Performance company so they could weld the TB`s right to the aluminium adapters made by themselves. They will do it again if you are interested for about 200USD for the whole lot + shipping. The PMO style manifolds sold here http://youroil.net/weber_carb_parts.html or Ebay or PP forum Airhorns With the big brands you have them in the kit. With Triumph stuff you can use the original ones bought on Ebay for quite cheap. And EFI Hardware can make some custom ones. Air filters Same as with the Intake manifolds. Most of the big brands use either ITG or K&N. But you can use sock type filters. In my kit I use UNI Filter Australia (yep, they are aussie) sock filters. Insulators and gaskets Usually you have them in the kit. But you can obtain ones here http://youroil.net/weber_carb_parts.html Fuel Rails Included in a kit. But for DIY - EFI Hardware in Melbourne can make whatever you want for a about 200AUD for a pair. Fuel pressure regulator Lots of options. Easy to get and to very expensive. Injectors Andrew at Rasant (http://rasantproducts.com) sells Bosch 300+ cc but it`s up to you. Just keep in mind that some ECUs have limitations on resistance. So, be careful and find out are they hi or low impedance and what your future (or present) ECU can work with. Igniters 1 coil, 3 coils, 6 coils or 6 coils on plug. Clewitt Engineering (http://www.clewett.com/index.php?main_page=index&cPath=1&zenid=delgghjkbe0963krilcnptqd17) has a few options, but there are cheaper things on the market. Again Rasant has some VAG coil on plugs option which is quite alright (http://rasantproducts.com/bosch-coil-on-plug-ignition-coils/). Fuel lines and fittings Well here are the art part comes in. You can spend hundreds of bucks for a aussie made stuff or make it reasonable cheap buying stuff on Ebay or in the U.S. In addition. There are two (feed line and return line) tricky (convex) angled adapters needed to use original Porsche metal fuel lines in the engine bay with any aftermarket solution. Common M14 to AN6,8,10 (or whatever) adapters don`t work. But it seems like we have at least 1,5 (yep, one and a half) solutions for that. The first one proposed by the guy named Boxter GT (in this thread http://forums.pelicanparts.com/porsche-911-technical-forum/389363-looking-fuel-line-fitting-size-2.html) the adapters might cost you anything from 30 to 50 per part. Another solution (I`m still testing it and can`t see why it shouldn`t work) is mine. You take a common adapter and put an O-ring at the bottom of the nut which has M14 thread and tighten the adapter up. The O-ring works as a spacer\rubber seal. Crankshaft sensor and\or camshaft sensor The most reasonable and easy to install is AEM EPM thing but you have to get an adapter which is sold on http://rasantproducts.com/engine-management-components/engine-position-sensors/ Other options are here http://www.clewett.com/ . There are lots of options really. Vacuum lines and fittings and\or vacuum distributor Ebay, ClosedCourseMotorsport, X-factory etc Intake air temperature sensor Same as above Oil temp sensor Same as above Throttle position sensor Same as above but most of Triumph TBs sold on Ebay have them. ECU and loom And pretty much none of those kits I`ve mentioned have any. Except the X-Factory one. Anyway, I`ll explain. Since Australia and New Zealand are full of this stuff it`s quite logical to buy one made here. Easy to get, warranty, tuner shops etc but. Rasant sells really nice kit based on AEM ECU and as far as I know provides you with the knowledge, experience and maps. http://rasantproducts.com/engine-management/porsche-engine-management-kits/ Same with X-Factory, Al has ton`s of power of knowledge and experience as well as maps and online tuning. And his weapon of choice is MegaSquirt - DIY ECU. Anyway, the brands are: EMS Wolf Link Adaptronic Haltech MoTec etc. depends on your budget. But be careful some of the brands sell their ECU with no loom so add another 300 or so bucks on a top. Air fuel ratio meter It is quite vital to get one, but most of the pro tuners have them, however if you`re in DIY tuning you can`t go far without one. The players here are: AEM, Innovate, PLX, Zeitronix, 14point7 and others. For the tuning purposes you need a wideband sensor and controller but for monitoring you will def need a gauge. Recent researches show that plx, zeitronix and spartan by 14point7 are more reliable and faster\more accurate than AEM and Innovate devices. But it`s a matter of argument if course. I really hope all of it makes any sense guys, trying my best to cover this so, if you have anything to add or to correct - feel free to do so
  3. So... I'm at the stage of starting to get a wiring harness ready for the 3.0 engine I am reassembling. The harness that came with the engine is a bit grubby but I think is still serviceable.. However, the multi pin connector that normally plugs into the rear of the car, has been removed for some reason. Here is a photo of what I have with the harness. Can I simply buy another plug and put it all back together? Does anyone have another plug? Also, since I intend to go efi, what do I do with all the extra connectors and plugs? Leave them hanging and tape them up? or undo the tape and trace them back and remove from the harness?
