So I guess im brining this thread back from the dead. Im going to do it in my Z32 2+0 for weight reduction and gas milage. Im making a touge monster:cool:
No one has done a write up on it yet on any forums and the only ones i have found are in japanese. heres a link : http://blog.so-net.ne.jp/grace555/ He has done the swap and I have been translating and taking notes for a few months now.
A nice thing that I've found is that the Sr20Det, with very minor modification, can bolt up to the Z32 transmission. Infact, it is frequently done in the Silvia world. This makes my job alot easier. As for now, I am waiting for some paychecks to get my project started. I am planning on using an S14 Notchtop Sr20det.
Hope to get this finished.

To answer "mtcookson"s question:
I am very happy with my VG30de engine. It is quite a monster, and have much respect for the VG engines. I am fimaliar with the SR20det engine though, and feel comfortable working with it. It is not veryt complex, and straight forward. The VGDE and DETT on the other hand is complex(for me) and is sort of a bitch to work on. Many things to worry about and maintain, plus its not my specialty.
Some reasons for my swap other then familiarity is the gas milage and weight.
With nice airflow bolt ons and some good at home rom burning and tuning, i can get about 27 to 39 mpg on the street. This is exciting to me. My Z is my daily, as well as my toy, and i will have 2 roms for the ECU, one that is set as economical(basically de-tuning), and one that is set to race(squeezing out lost power). Plus, it is not very hard to get 300hp out of an Sr.
The weight, as we all know of the Z32 is beasty. If i were running a 2+2 version i would not have thought about the Sr in the car though. That would have too much weight in strange areas to get a nice weight ratio. It has seemed to me that doing basic interior strip, fiberglass rear hatch with plexiglass, and swapping seats for racing seats has lossend up alot of weight. Some carbon fiber here and there with the engine mounted as far back as possible will, in my mind, give me a nice reduction of weight.
