  1. I am currently in the very early stages of a ~300hp L28ET build and am just trying to feel out what I want to put behind it. The car is 73 240z and had an L24 with an auto in it and barely ran, so I barely have any seat time in an S30. I know very little about the cars history so I am not sure if it was originally an auto car. When I bought the car it came with, what I have detemined is a 4 speed in the trunk. So far, I havenˋt opened the rear end to figure out what gear ratio that I have. I have been doing the research on the options, but know very liitle about the hp/tq specs of the transmissions that I am thinking of. I want the car to be a daily driver with some spirited driving here and there, maybe the odd track day. Relaibility, Longevity, and drivablility of the drivetrain would be my main concern. Options: Rebuild the old 4 speed. I dont know much about these. Some of the info that I have read seems suggests that these can be crap when trying to put more power through them? 240sx 5 speed swap. Thinking the swap kit from Godzilla Raceworks. Trans good to 400WHP? For each of the two options what would be a good final drive ratio or rear end setup? I know there are alot of options with a varying degree of modifications necessary. Am I more likely to blow out the ring or pinion, or a half shaft on the R180? LSD options? Thanks.
  2. I am looking at options for the engine build on my '73 240z. The car came with a L24 (E88/P30) in it, that ran when pulled. When I bought the car it came with an L28 (N42 block/ N47 head). I have not opened up the L28 to inspect it, but the engine does seem to turn freely. I don't know anything else about the history of the motor. I would like to work with what I currently have. I have done my research but, it all gets so confusing. I am interested to know if the L28 setup would be worth attempting to turbo? I know that the P90 is the preferred head when it comes to going turbo, but that is proving hard to find. What would be recommended to make this setup work with a turbo? Remove the liners in the exhaust ports? Pistons (flat top or dished)? What else would I have to do? At this point am just looking at whether or not I have a good base to start with or just wasting my time. I am looking at making this car into a 300hp daily driver. Is this realistic with what I have or am I just dreaming? This is my first build so please bare with me.
