Default 1jz & 2jz block compair

I just bought a 1jz engine and its seems to be the wrong one for my sc , the engine I got has the oil pan towards the front of the engine. I think this is hit my crossmember. Ild like to know if sc 2jz bottom pan and related parts will bolt up to the 1jz to correct this problem. I dont have the engine yet so this is why Im asking

don't know if this is helpful, but here goes...

The 2.5 liter 1jz-gte was the succsessor to the 7m series in Japan. It was offered in JZA70 MK3 supra as well as the Soarer(lexus SC series here) and the Chaser. Possibly others, I don't know 100%. There are differences between the various verisons of the 1j. Some had tractions control, some had front sump oil pans, some center , some were twin turbo while the later ones where single. The later ones also had top feed injectors while the twin version uses side feed.
First paragraph of Toypro's quote.

people tap the oil drain line when they do the turbo kit on the 2JZ-GE -- it shouldn't be an issue.
