i have an s13 with an rb25 an an r33 subframe. my problem is that the engine sits too high with oem engine mounts. i have found shorter mounts but these puts the engine more back and i dont know if it will fit with the head drain kit i have on the engine. is there anyone that have the same swap that can give me some info? {}
"Head drain" is basically just an added breather for the oil sump. You can just weld a fitting and add a breather hose/tank for the oil sump and save the space behind head. There's a massive oil control topic on SAU forums that is well worth the read. https://www.sau.com.au/forums/topic/110680-oil-control-in-rbs-for-circuit-drag-or-drift/ Edit: Now that I read your message again I see that you have the drain kit already fitted, so my post might not be the most helpful
Do you hve oem intake manifoild? Because i have to use the oem to get my car street legal. But it touches the hood with oem mounts
