Hi guys I'm new to this forum stuff but thought it would be a great idea to join to try and answer some of my questions I have. I have a lj torana with a Nissan rb20det in it. Motor is from a 200zr z31 fair lady. Trans is a 4 speed jatco box from a r32 that is fully manulised with work done to the standard converter and shift kitted. Diff is a ford nine inch with 3.55 gears. Mods to the engine so far is 700x300x75 front mount inter cooler, rb26 injectors, autronic sm4 computer. As you can imagine I'm struggling for power at the wheels(145kw) at the moment. First question is What is the turbo on my motor, it is still standard? I want a bigger turbo but am struggling for room so I want a turbo that has the same outside dimensions but bigger internals. Is the possible, or will I have to make an adaptor to mount of my exhaust manifold. Second question is what ratio diff do z31 200zr fair lady's come out with? Is it 4.3??? I want to change my diff ratio to something lower and was thinking 4.11 or 4.3. This is a street driven car with a little highway driving! Hope someone can help, I'm desperate for more power !!!!
