I’ve been referencing multiple sources in order to Draft the components of the vehicle in the correct dimensions. I’m sure it will be a lot of fun later on when I have to utilize the nifty and oh-so-neglected caliper http://www.bmicanada.ca/images/digital_caliper.jpg to confirm all of my dimensions. The trouble I’ve been running into is what Nissan is giving me, via their FSM (Factory Service Manual).
I must say that I love this manual as it provides me with the bulk amount of chassis dimensions in both 2 dimension and 3 dimension. The reality of the fact is that Nissan has a 3d-digital model of the entire car somewhere via whichever software they use (ie: Samson PLX) a program which Fiat uses to develop their own vehicles. Unfortunately I would not know where to begin, or, whom to pay, to get these cad models/drawings because that would make my life a whole lot easier. For now, I have to work off the FSM, but I only wish it was more correct. As you can see in the picture above, the ‘body & trim’ tab provides me with chassis dimensions.
As I have been drawing out the chassis, I have utilitzed certain horizontal reference points and followed precisely to the point, but my chassis drawing looks TOTALLY different, not to mention that some cross reference points have a 2-3mm variance. This confuses me… I don’t want to continue modelling off of the wrong dimensions but I’ve done everything correctly.
Anyhow… I’m sure I’ll be able to sort that out. Other source I have utilized are http://www.rockauto.com and http://www.wilwood.com. Rockauto provides aftermarket and OEM replacement parts for multiple vehicles and not only that, the manufacturers create profiles of the parts with DIMENSIONS. Just what I need. Wilwood is good enough to it’s customers to create PDF profiles for each individual component and that is how I’ve been able to dimension my brakes and rotors.
I see the beginning of some brake ducting in there. But then again… it is MY drawing. I will be off to Vancouver tomorrow and I will be back on June 8th. From there I hope to show you guys some before and after shots of my KA24DE head.
