After watching the video of the Zed with the 2JZ motor posted by Grant, I have become inspired to do something similar with my Zed. I am thinking about using one of the Nissan V8's (VK45 or VH45) as a base and then adding twin turbo/supercharger to it. As I have done very limited research and have zero knowledge of the Nissan V8 motors I have no idea if this is even possible. If anyone has any knowledge about this sort thing I would greatly appreciate any advise or tips. My main concerns are: a) Will the VH/VK fit in the Z32 engine bay (without cutting into the firewall) And will there be room left to fit up the twin turbo's! b) What sort of transmission does the VH/VK use? Bolt pattern, etc. Is it compatible with the Z32? c) Other modification? Trans tunnel? Tailshaft, etc. What else will I need to change? If this project is not too cost prohibitve, I am very keen to take it on.
Have a chat to John at UAS he has been contemplating this project and may even have started work on it. Ben

Paul your crazy buddy you just built a vg30 and now you want to move on. Any way if you wanted to do this project i would either buy a really cheap 89 model z32 (15year rule thing) even better if you find one here with a stuffed engine, or consider fitting the engine into a 260/240z shell. vh45 is meant to be really good, same block in the nissan r391 supercar (but destroked) with twin turbo, also same for one of those indy cars if i remember right, and possibly in the stillen race z32. Most importantly do some research and see if you can get a hold of performance parts, the one with more support will cost less as custom work always costs more.
Yes you can There is a company in Japan that has done quite a few. Jeff from SSS Automotive has been to and or knows of this company. He has a Jap mag that has a story on one. IF you are serious call Jeff 02 9896 6111 who prob has engine in stock. His specialty supplying engines for conversions. Don't call him unless you have the ability or know of workshop willing and able to do the job and have many thousands lined up. There is a lot involved and yes custom tailshaft and depends if staying auto or if want to go manual as custom bell housing etc and it is a long term and expensive project. The good thing is YES it will fit and can be done. The motor is a little lighter than the VG as the block is alloy. Zed DUDE ette knows of one in Sydney out in Penrith. It was imported with 4.5 litre Nissan Infinity motor and twin turbo. I have spoken to the owner but I have not seen it but I think ZED DUDE dette has. It would be an awesome beast. It would be much cheaper and easier to do without the turbo's. They are a awesome motor very well balanced and very strong 6 bolt mains etc. Another option is I am doing a VQ conversion 3 litre alloy block 100kg lighter and lighter rotating mass and revs better.
In your research......>> Try and have a chat with the guys from Escort racing in the states (they run one of the 7 second Z32 drag cars) as thay have done it.

hypothetically speaking, just gue$$ing hypothetically speaking, just guessing i.e. "dont take my word for it" : cost including hypothetically labour of getting a professional-mechanic engineering-certificated job done. # buy a VH45 Infiniti front-cut ($2500 to $3500) # beg-borrow-steal a used 300ZX front-cut. (free-$500) # decision to keep the VH45 auto gearbox or cost of custom bell housing for manual (gue$$ $$) # dropping current engine (gue$$ 1000) # service and/or rebuild of VH45($1000-$3000-gue$$) NOTE: do the majority of the developement (i.e. custom work) in the 300zx front-cut. # custom cross member and engine supports built in 300zx front-cut. (gue$$ 1000) # custom headers to mate with existing exhaust system (gue$$ 1000-$1500) # engine install into target car (gue$$ 1000-$1500) # electrical wiring interface to zed (gue$$ 1000). # custom one-piece tailshaft (gue$$ 1000) # tuning and run-in (gue$$ 500-1000) # engineering certificate (gue$$) that's just hypothetically speaking so I would not expect much change from $10,000 would not be surprised if cost more like $12,500 to $15,000
WOW. Thanks for the great response guys. You have all given me some fantastic information to start with. Now that I know it CAN be done, I will just have to find the best way to go about it. The idea of buying another Z32 (blown motor/damaged = cheap) might be a better option. Although the money from the sale of my current engine would definately help speed along this project. I'll look into pricing for parts and labour as suggested. If I'm lucky I may be able to find a sponsor to help cover some of the costs. I'm sure it would make a great demo car. Damn you Datzboy for finding that motor on eBay!
