To the CIH engine connoisseurs (Hello Reinhard): as assumed, the piston bridge of the 1st cylinder is broken at the typical place. The engine had 9 bar compression on Zylidner 1 at the purchase condition of the car (was running flawlessly, slightly restless in idle) and after compressor conversion it is now completely broken, 3 bar residual compression. The following question arises to me: 1. Can I easily install another used piston? 2. Can I use the old pistons/oil stripping rings again ? 3. Who has a piston left? (the defective one has the measure 94,94)? 4. What do you say to the wearer image of the condenser bearing? (will all be renewed) Do not want the engine to be renewed, it should simply run for a while with c30ne cylinder head and compressor. If this does not work like above, comes in after a small overhaul of the available c30se, without compressor booms Many greetings Christian

Hello, from which material are valves? According to the weight, the material has to be quite hard. However, I have found that you can easily file it?! Magnetically the valves are also – does not conclude on stainless steel?!? …but why don’t they rust then? Thanks for the Enlightenment Jens

hello have a c20ne and would like to build a sports camshaft pure but which ??? 272/276° ??? and now please do not answer with 296 degrees or so what has the original injection and or which injection and which nocke ???

So hello guys, I have questions: I got 2 months ago an Opel Kadett E-CC GSi 16V. The previous owner has tuned the Kadett to over 220 ps. Now I have the problem that the engine does not hold. I registered it and the next day I already have a valve guide damage, I broke a valve and pulled the pistons 1 & 3 quite in sympathy. The car was completely rebuilt in May this year and the engine was repaired at Mantzel (confirmed Now I have bought a new c20xe engine at ebay which has just 150tkm on it. Now I am standing in front of the question the tuning parts again or not, I mean if I have the tuning parts built again this time, the motor will be too scrapped again or will hold it this time. last time the engine broke because I overturned the car, the car has a chip inside the car and the engine will be broken. A little bit in the top drives 8240 rpm. So what do you mean again with the tuning parts or should I rather leave the fingers of them and sell the parts at ebay or something? these are the tuning parts built in in the motor : mantzel suction bridge (inlet outlet channels extended) ECU chip fan-curved sharp cam shaft (272°) lexmaul sports exhaust system (from KAT) overall the part has 224hp which unfortunately not hold, although my uncle says that this is a miracle I would be happy if the “connoisseurs” would tell me which decision will be the cheaper one for me (long time). By the way, I don’t pay any labor costs because the engine will be removed or installed by my uncle. the problem is that I can’t buy a new engine every week. I’m happy if you could help me!

Hello guys, we created a shell diagram for an Opel MV6 3.0 engine in the university. Did I understand everything so far, but I couldn’t answer one thing and why at high speeds and small throttle angles which are extremely high? I am very grateful for any help!

hello, there are for the astra f 1.4 two engine variants that a 1.4i the eu model with kat and 44kw den si without kat (for the Swiss market) with 60kw my question or questions are now (of course only hypothetically seen) if one would have to remove the kat with the eu model to get to the 18ps extra power also the control unit from si use or can the control unit from the eu model so out of list e.g. disconnect the lamda (which, however, has the consequence the control unit i n the emergency mode changes) that it would have the same effect since I only pose this question hypothetically as I said, please refrain from moral statements (as I know it is not allowed in the stvzo) and would be very grateful for detailed technical assistance

good tomorrow forumler, I have a question which refers to the increase in performance at my GSi. The machine is the c20ne and I have the following plans, as I get to the parts well for me: – RAM Induction – Fan Curvature – Group A (with absorber technology) – Power tube (instead of hose) I now went out to take the approx. values and counted from machine down to ESD (I also don’t know if you can do it that way) 85kw + 5kw (Ram) 90kw + 6kw (7% by fan k) 96kw + 6kw (7% by group) that would be under best conditions, purely computational, around the 102kw, which would then be available to me almost at the acceleration. In case that I would set the 130 chip pure, would the values according to my understanding almost once increase. 95kw + 6kw (Ram) 101kw + 7kw (7% by fan manifold) 108kw + 7kw (7% by group) about 115kw Or can you not calculate that at all? Finally, the controversial question arises as well. whether you could not tickle out 1 – 2 kw or at least stabilize the performance by means of suction optimization, i.e. the so-called power raw & other self-built, and by inserting 16V valves & tuning of the whole, or even 1 – 2 kw.

Hello since I have already gone through all search engines but still found nothing suitable now my questions! And I bought today an Astra F with C14SE as a butcher and wants to install the engine in my Corsa because my C12NZ will soon make the Muck! Installing the engine makes me no trouble, much more thought I make the thing to wire so that it works! Do I have to take the motor cable tree out of the Astra and where do I have to connect the thing? Do I have to change anything else about cable technology? I’m loaning electrical engineering at Opel but you want to learn about it and it can’t be that hard! I would be happy about helpful answers. mfg der Robert
