I think Kalle had angles in his NA engine?
That is correct. Very high compression in combination with special JE pistons made the engine extremely narrow even with 5.7" rods. I used a 2" stepped custom exhaust based on a Berg system as well. It fitted without cutting in my old 65. Very fun engine, especially between 5000 and 10000 rpms  Have a nice Xmas evening. -BB- |

Hi, reading all your experiences about those 4" engines I decided to build such an engine sometime as well so I bought an Limbach (aircraft) oxyboxer case some time ago. Nothing happened for a long time but recently I started collecting parts for that engine and started with modifying the crankcase. The plan is to do as much of the machine work by myself as I recently bought a milling machine and a lathe and want to learn machining engine parts. Two weeks ago I started to clean the crankcase, remove the studs, drill and tap the oil galleries and bore the case for 4" AA cylinders. I machined the case to 104.6/105.1mm and turned the cylinders down to 105.0mm at the case side. At the moment I do not have all necessary parts to trial assemble the engine, yet but as soon as everything is here I will know how much to shorten the cylinders and will finish them. As some of you asked for different engine combos, here is mine: - late oxyboxer case - DPR 86mm WBX crank - 228mm flywheel - 4" bore  using AA cylinders and 4" Keith Black Icon flat top pistons (1.09" compression height, lateral gas ports, 0.927 pin) - rebushed CB H-beam rods, 5.6" length - Thorsten Pieper tool steel lifters, 56gr. in modified aluminium bushings - dual tapered aluminium pushrods - custom grind camshaft with Magnum straight cut gears - Thorsten Pieper CNC cylinder heads with lots of cooling fins - stainless steel inlet valve 49-50mm (not quite sure, yet) - exhaust valve 39.5mm, natrium (translation?) filled - Crower valve springs/titanium retainers - 50.5mm IDAs at first, fuel injection later - header size probably 1 7/8", but thatīs not defined, yet - dry sump That engine will hopefully be very streetable with lots of torque as iīm sick of trailering my car to some quartermile races 2 or 3 times a year. Letīs see if I will achive my goal...  Attached some pics of the parts and machine work so far. The pics donīt show my own heads but some with 46/39.5mm valves.

Very nice to see a good radii in the Autolinea case conversion.
Also very good idea with the roller conversion, and how you retained the roll pin that prevents the lifter from turning.
I also like the large radii in the inlet ports of the comp eliminators.
Thank you for sharing your work!

Hi mexx, thats some very nice parts you have there,and the machine work looks real good,are you doing all your own machining? and is the head work all done by you?[porting etc? ] are those autocraft heads the same casting as CBs strip dominator? cheers richie |

Hi Kalle, no certain hp goals to achieve. I hope to be able to run mid 12s and still have a very streetable engine. That combination of parts will be trial and error.;-) Tobi |

Hi Richie THX for the more than kind words. I'm doing everything myself from concept to reality. I also do all the machining myself. The heads were bare castings from Autocraft an were handported by me. Yes it took some time. It is basically the same casting as CB strip dominator MeXX |

Hi Tobi I see that your things are coming together. Are you happy with the KB pistons you got from Summit. Post some pix . I would be interested how you made your dry sump set up ?? what size are scavenge and pressure pump how is the routing ? mine is: Stock pickup tube - scavenge pump - oil filter - thermostat - oil cooler - dry sump tank - pressure pump - oil gallery MeXX |

The pistons are still in the USA at a friend of Mine who will bring them to Germany in his luggage when he will be on a business trip by the end of january. I will send some pics as soon as I have them here. The TP dry sump pump usually has 26mm pressure and 38mm scavange gears but mine will be modified for 30mm pressure gears because I plan to install oil squirters as well and I'm afraid that the 26mm gears wouldn't be enough. My dry sump system will be plumbed the same as yours but I will try to use the stock oil filter location with a short filter....maybe that will clear the header?! BTW: your (machine) work is great and really very inspiring to me! It seems that you have a lot of experience in building 4" engines. Which engine case (WBX or Autolinea) do you prefer and why?
