qikz Posted February 12, 2009 Share Posted February 12, 2009 This is specialised! I am converting a 350Z to an awd system. I have several gearboxes and a pile of stuff to commence. I tear things apart to familiarise myself with just what engineering is ahead of of me and I discover some obvious differences in transfer case operating systems: The G35X has a "Clutchpac" system, which is electronically controlled. It is very tidy. The BNR34 has a "Multiple Clutch" system that is electro/hydraulic controlled it is more complex. The G35X is a later version of the Transfer case system, however its only on the end of an auto transmission which isn't good for my use, so the Getrag V160 gearbox (BNR34) is being used. Which system will provide me with a superior result? Is the "Clutchpack" system of the G35X strong enough? The Clutchpack seems to be electronically controlled so does it have a variable torque capability or does it simply lock? Does the Multiple Clutch system offer more options for tuning? Don't concern yourselves with the fitment of either system as engineering fitment is my hobby and we have the resources to rebuild or fabricate anything. Yes, the bellhousing will be recast to fit the VQ35 engine as a factory fit. This site seems to be jam packed with intelligent debate and a smattering of engineering input so I'm hoping we might be able to discover a scientific solution rather than pure opinion. The problem really, is finding anything meaningful on the "Clutchpack System". Quote Link to comment Share on other sites More sharing options...
ckolander Posted February 12, 2009 Share Posted February 12, 2009 Search function will be your best friend. After that, a very hefty bank account to fund this project(btw its already been done, some shop in Japan). You're gonna have to do a LOT of custom fab work, good luck.

The chop shop was JUN. They grafted a 5 speed onto a high HP Z and the rest is history. I believe it a rough job but thats my opinion and it was for the track. Mine is for the street. The other one is Function Tuned (in NY?) an auto conversion (probably the easiest as its a straight transplant with a mild engine as the auto is limited in capacity) I have the BNR34 6 speed box (V160) and a V161 Getrag (Supra) as an alternative to give different ratios, so its all there. And yes I will require a longer and stronger input shaft which is already under way. A LOT of custom fab work for you is a piece of cake for me. Perhaps a LOT of money for you is petty cash for me, but were not here to discuss cost , originality or workloads, but torque control systems. I realise the search function is the best friend, but we are in unchartered waters here and I'm actually after some specific knowledge about the two systems. Now it could mean that I will be writing up the differences and pros and cons, but if there is an intelligent life out there, I would like to hear from Him/Her and avoid reinventing the wheel if at all possible. Cheers and thanks. Quote Link to comment Share on other sites More sharing options...
qikz Posted November 19, 2009 Author Share Posted November 19, 2009 Just an update for the interested. Finally there is some movement and the electromagnetic clutchpack is a better tuner, lighter, and can be used with existing electronics. I have had to reinvent the wheel as it hasn't been explored to date. Its somewhat similar to the new GTR35 with more robust shafts etc. With a new shaft it has been fitted to the BNR34 Getrag transfer case which can now be used behind the VQ35DE VH45DE etc., giving alloy V8 and 6 cyl awd alternatives. Its been an expensive but somewhat rewarding journey. Quote Link to comment Share on other sites More sharing options...
aliphian Posted November 19, 2009 Share Posted November 19, 2009 I couldn't imagine an AWD VH45DE! Great work. So how does this AWD system compare to Nissan's ATESSA-ETS system? Is it more like the system in the Mitsu EVO? Quote Link to comment Share on other sites More sharing options...
qikz Posted November 19, 2009 Author Share Posted November 19, 2009 This uses the ATTESA - ETS system from the later versions, including computers reading the sensors on all 4 wheels and interacting with the original Control system . That should read VK45DE too, which is the later version V8. We will be developing a 5.1 TT (stroked 4.5) probably next year after I get the Z up and finished. The AWD system will be available in a kit form with instructions etc for fitment to the G45X, G35X, 350Z including the chassis mods for the Z (minor stuff) for the fitment of the original awd system and drivetrain giving it "Factory Finish". I am having the Drawings done now for the gearbox casting process and engineers reports for the bellhousing etc for the commercialisation of the conversion products. Isn't that process bloody expensive! Fully converted Z's can be done by my workshop and brand as the KAMI Z with either the V8 4.5 or the 3.5 V6.
