I've done a lot of research and have read about many engine swap stories, but I still don't know what to pick. I don't care if it's a Nissan, Ford, Toyota motor, I just want something that'll work for me AND my budget. Basically I'm planning on taking my future Z up on mountain passes, so I want it light enough so it can run downhill with ease, and at the same time it can compete uphill against high power AWDs.
Well the 240Z weighs around 2200-2300 lbs, so even 250 horses is quite a lot for its weight (or so I think). An SR20DET seems to be a good choice due to its minimal weight. However, I feel sort of uncomfortable having so much extra space under the hood (which seems like a waste...)
A V6 turbo would be nice, but a little pricey. The RB25DET and RB26DETT are popular choices and I've heard the RB26DETT can go up to 500-600 horses with ease, but I don't need that much power to go uphill... The 2JZ-GTE motor seems to be a popular choice as well, but the costs are just about the same as the RB26DETT (or so I've heard).
Finally, the ever-most popular swap is a small block Chevy. Or an LS1. Whatever, a V8 engine. While it has a lot of low-end torque, I don't think it's the best option for windy roads. Besides, I like the sound of turbos rather than the roars from muscle car engines.
Right now I'm considering the RB25DET, but there's the problem with boost lag around each and every corner. My friends tell me I can get rid of it by adding a new blowoff valve, but I highly doubt it's that simple. Maybe I should get a supercharged V6? If anything, I want something light, powerful, and fits under my future Z's hood just fine. I don't know, I guess I'm just overwhelmed by all the available options there are for an engine swap.
