I was wondering if you guys could help me out? I have a s13 hacth that I'm building as I get money but my plans were to get a 1j for it but they have told me it's difficult to find parts for a 1j so they told I should get a rb25. I wanted the 1j because it has more torque and power stock vs the rb but if I decided to go with the 1jz I tried doing research because I belive there is a clearance issue so they get the 1j with the front oil sump but I'm not 100% sure on the so I was hoping someone could clear that up for me. Let me know what you guys think about this so I could decide on what would be better to go with and thank you any info is appreciated.
