[Interesting Independent 240z Design]

That is the tightest looking car I've seen in a long time. I wish we could have a tail shot.

Ok, thanks.

Anyone know the difference in weights of the "A" box and "B" box trannys?

[What is your Top Speed. On or Off Track.]

I had him all the way to 170, and then his lightweight headlights gave him the slight edge and it was all over.

Actually, stprasinz tells the truth. I raced him with my stock 86 300ZX n/a and he beat me! So then I put in a mild set of cams and we raced again. I almost had him but I blew the welds on my intake so i figured I better shut it down.

Thanks guys, you're knowledge helped ease my mind. I was beginning to think that I shouldnt even go look at this '71 because I just had to have a '72 with the better(factory) upgrades.

 

My budget will barely support the purchase of the car, much less any modifications. So if I can just pull stuff off the 72 and throw it in the 71, it might be worth it if the car is really solid. As far is the 4 spd Vs 5 spd goes, I already have an '86 300ZX with the 5 spd, so I think I wanna try a 4 spd for a while. Thanks again.

Nice job, you're car looks flippin' awesome. That color really highlights the wheels.

Jon,

Can you describe the modifications needed to make the newer trans fit in a '71? On the engine side of things, I am wondering if the trans will bolt right up since the engine has not changed. As far as the shifter goes, how much will need to be cut out of the floor?

['71 to '72 diff location / transmission swap?]

Actually, Greg wasn't off topic. I did ask about the differences in transmissions. Maybe I need to ask my questions more clearly...

 

Is the new transmission and shifter mechanism for '72 better than the one in the '71 I am going to look at? I can not find specs for comparison, and I haven't driven either model year.

 

Does anyone know if the longer wheelbase of the '72 is better for handling and weight distribution because of the repositioned rear end? Thanks for everyone's help so far.

['71 to '72 diff location / transmission swap?]

As far as the series thing, I was referring to the changes in the 240 specifically, as noted in the Production Changes 69-73 section at http://zhome.com/.

 

So, if I pulled the driveshaft, mustache bar, and front diff mount out of the '72 they should just bolt up? Or would I need to fab something up? Thanks for your help.

['71 to '72 diff location / transmission swap?]

I know that there were some changes from the series II to series III Z's, including a new tranny design and the rearward movement of the rear end by 35mm. What I do not know is what all was included in the movement of the rear end (as far as mounts, suspension, brakes, etc.) and what improvements were made to the tranny.

 

I am considering buying a clean '71 with a '72 parts car. I want to eventually use the car for autoX/track days, and am interested in making a great handling car. I have been looking for a rust free '72, but this '71 looks (from pictures) pretty decent.

 

1.) What parts were moved in the switch to the series III cars? How was the trans revised or improved?

 

2.) Do the improvements made to the Series III cars make a noticable difference in handling/driving/maintanence?

 

3.) How much work would be involved in swaping out the noted '72 parts into the '71 to effectively make it a series III?

 

4.) Would it be easier, or would I be better off, to just wait till I find a really clean '72, rather than building a '72 out of a '71?

 

Any help with these questions would be much appreciated. I have not went to look at the cars yet, as they are about 3 hours away. However, I would like to know what to expect when I get there. Thanks!

[auto to manual swap]

So, interior wise, I would just have to get a pedal set and shifter/boot to transform the car? Everything on the other side of the firewall should bolt on the same as if it were a manual trans to begin with, correct? Is there any cutting or drilling of the firewall/shifter hole?

 

I read in one post about a brace that needs to be installed so that the firewall doesn't tear at the mounting point for the master cylinder. Is this something that would be on a manual trans car that can be unbolted or would I need to fab one up? Also, does the manual trans itself bolt up the same as an auto or will I need to make mods there as well?

 

Thanks to everyone who has given input. You guys don't know how many auto cars I've passed up because I was unaware that there was a relatively easy swap for trannys. Im definately a noob in the field of Z mods. HybridZ is a killer site and you guys are a ton of help. Thanks - Kris

[auto to manual swap]

Ok, thanks. I am looking at a late 70 240Z. Its an auto, but i heard that they can be converted by removing some "plate" in the firewall, so I was wondering if this is correct.

[auto to manual swap]

Does anyone know if a stock clutch pedal setup will mount in the same as if it came from the factory? is there a plate of some sort on an auto that is removable to be able to mount a up a clutch pedal and linkage?
