alternativez2003 Posted December 12, 2003 Share Posted December 12, 2003 As a matter of fact, at least in my mind, some of the strongest most reliable engines, and they are very easy to work on. I've had some postings on the HybridZ forum under the other engine category, but got only a few responses. I have owned several mid '80's and my 85 635 Csi will soon become the donor of its entire drivetrain and electronics to my 1970 240Z. I lowered the 3.5 from my 86 735 into the Datsun and the fit was very nice. In particular, the pan fit so well behind the crossmember and below the steering knuckle of the rack, I was amazed. The rearward placement distributes the weight better, it would seem, than the original six, so additional weight would not be such a concern. An M engine would obviously be an excellent choice, but I have the 635 and know it well, and it flies, so I'm sure I will be pleased with this power in the lightweight Z. I am interested in refining the intake of the NA 3.5, replacing the huge, boxy crossover intake with something smoother from the left side. That would clear the top of the engine of a lot of clutter and actually lower the center of gravity of the tall engine somewhat. It would also more resemble the configuration of the 2.4 with a crossflow head. I just think this would be an improvement in the effiency of the intake and therefore improve power even if only slightly, while improving looks greatly. I haven't found any intake options for the regular 3.5L, so if you know of anything, please let me know.

datsunlover Posted December 12, 2003 Share Posted December 12, 2003 Hey man, that is good news for me! The wheels are turning in my head... I've liked BMW's since I was a kid and almost bought one a few years ago. Unfortunatly the $$$ required to fix the seamingly small problems would have been too much for me to handle. (brakes, tie-rod ends, exhast, ect) So I bought an 85 200sx. The thing that has stuck in my head since then is what an amazing engine BMW makes; I wound that thing out in first and second and it was smooth all the way! Good low end and free reving. Good thing it was standard to because after shifting to third I realized the car had no brakes! A blown line in the rear that the seller 'forgot' to tell me about! Jerk. I heard the rear tires lock up for a second as I ripped it back to 2nd to slow the car. (I was only doing about 70K! ) As I recall, it had a good 200K on the spedo, and still fired up and ran great. Seamed to be a good stout 5 speed too... As for the intake, wouldn't it be possible to fabricate something? I'm sure it's been done before on a datsun.. so why not a BMW right?

alternativez2003 Posted December 15, 2003 Author Share Posted December 15, 2003 Thanks for the response. I notice you are in Ontario. I've been communicating with Charlie Osborne of Zedd Findings and a guy named Rick at Bradford Nissan about some parts. I know Ontario is a large area, but I just thought it was interesting. Sorry about that rear lower section in the picture; is that your car? I feel lucky, my 70 is in extremely good condition, but then it's been in my garage for about 15 years, totally stripped down. Actually the only time behind the wheel was towing it when we moved it a couple of times. Sad, I know, but I have so many DIY projects, it has been waiting. I am really getting anxious now, as I turned 50 last August, and I want to get it going soon. As a matter of fact, my daughter is planning to give me her 325 that I gave her a few years ago as soon as she and her husband take delivery of their new Mini S, so I am hot to take my 635 apart. It may sound odd to dismantle a decent car; a 635 is a nice auto, but as you noted, lots of little things get costly, and if I am spending money on a car, I want the Z and I really enjoy the 635, so I think they will make a great hybrid. Let me know if you get any great ideas. I check the forum when at work if I have a chance. We are in central Indiana, about 30 mi north of Indianapolis.
