Hello everyone. Is anyone interested in seeing what a worn-out engine looks like after more than 350,000 km? This incredible machine has never stopped. From the very first day, it was driven quite fast and under full load. On the other hand, it was taken care of and cherished like a pet. Now, the time has come to either throw it away or repair it and refine it in detail. I don't think I can throw it away. I've been waiting for another sports car for everyday use, but that just hasn't happened. I bought it new in Slovenia in 2005. In the meantime, nothing has impressed me enough to replace it. The new models looked ugly to me. Especially the Mk 4. The fridge door handles, the miserable screen inside, and the unnecessary amount of doors disappointed me. The engine has already been removed and disassembled. I'm shocked at how dirty it is inside. The oil I used was a disaster. Pictures are coming next
Can someone tell me or recommend which valves to buy for the Meg 225? I am not interested in power over 300Hp. Alsoo i read that an oil pump from a diesel engine is used for increased oil flow. How smart is that, considering that a gasoline engine runs at higher RPMs ?
The only valves I would and have used are the supertec ones, I would also replace the valve springs as well, due to the original ones being a bit soft. Yes you can fit the diesel oil pump, I got mine from pure motorsport, you might have to remove some bit of the webbing in the sump though. Two I've done had to have bits removed, but one I did didn't need anything removing
Thank you for the answer. The diesel oil pump is designed for lower RPMs, and that part concerns me. Does replacing the pump increase the pressure? Has anyone measured and tested that? The idea is that the engine will not be pushed to high power—let’s say no more than 300 HP. I want it to be usable in normal driving conditions. The track is not an option since we don’t have one here. In other words, I am more interested in making it durable and fast without excessive tuning.
The diesel pump is set at a higher pressure and gives a higher flow, I have one in my 250, that's running 440hp, I've put one in an engine I built that's running 300 and in another running 482hp, none of us have had any issues. I did notice that when tracked my R26 (405hp) that the oil pressure on idle after a few laps was really low, not low enough to set the alarm off though. If you have gone to the point of stripping the engine right down, then I think it's a no brainer to at least replace the conrods, then you might as well fit some forged pistons, then you.know you have a solid engine for what ever you want to do with it.
42129[/ATTACH] Everything needs to be replaced. I'm changing everything. The pistons can't be used on the first special size—they require the second one because they're worn out at the top. New connecting rods, valves, and bearings are going in. I'm currently searching for parts, and it's proving quite difficult. I found a company in Romania that can offer me quite a lot, and the rest will come from Engine-Dynamics .
