    1JZ Front to Rear Sump

    Hi, I'm currently swapping a 1JZ VVTi into my mkiii and had to convert it from a front to rear oil sump. I ran into trouble when the oil return line from the turbo to the oil pan no longer fit. The return line is formed rubber and I believe the part number for the front sump is 15491-88401. I also found a part number for what is described as the return line for a rear sump, part number 15492-88401, but this line does not fit either. I've seen braided lines online but surely there is an OEM replacement part? Any help is appreciated! Thanks!

    Hi Scotia! Go to the facebook groups and ask to purchase a used set of oil return lines and the elbow. There are HUNDREDS of people that have switched to single turbo and I imagine a bunch of them have parts just laying around.

    Hey thank you! I'm running a single turbo but I'll definitely check some facebook groups and see what I can find!

    Oh if you are going to single turbo just get a -10 AN return line kit. Driftmotion has them

    Check this diagram out. It is from a 1998 Toyota Soarer with a rear sump 1JZ VVTI with the oil return line.
