Hey guys! Well its that time again, the winter is officially over and warm weather is just right around the corner (for some of us). Ive been working on this car for a while now, and I think ive done enough to show a little off to the community. So thanks for tuning in, and dont forget to let me know what you think whether you like it or hate it!
History/Overview
Ever been just surfing the net and run across a sexy 240 like the white coupe from FL or the drift/track cars and just yell out "Damn!" Well for the last few years ive been on a mission to find a "factory stock s13" 240 that gave me that feeling, but I soon realized that there is no such thing as a super clean stock s13, there just not out there anymore. Maybe im just to particular? So I took a step back, and thought about building my own s13 from the ground up. Crunched some numbers and did some research and now I think im ready. Ive owned more cars than you can count on your hands in just a few years, but there's one I just never could got rid of, its an Black 1989 Nissan 240sx with less than 90k on the title. So i pulled the tarp off, pushed it in the garage, and been on full throttle ever since... My main goal is to just build a clean s13 that people can see and have respect for, no body kits or any "honda fanboy" mess (let the flamming begin), just a super clean coupe that might inspire more people to get into Nissans, much like most of the builds here on NICO. =)
Nov 08 - Jan 08
It took me just over two good months to strip the car down completely and document where most everything whent (college sucks), ive taken cars down this far before and I always spend 4-5 extra hours looking up random bolts and brackets, trying to figure out where the hell they came from? So this time around I label all the little things that I know ill loose... One thing ive never messed with wiring before and ive been stressing over putting it all back in the car, so ive taking extra care of labeling the harness's. Taking everything is easy, but I got to be prepared to put it all back in it at some point... So at this point most of everything is out of the interior and ive started on the sound denting. I didnt do the dry ice method because im dumb, I didn't the "torch and scrap" method, which I would not recommend. I spent 75% longer doing this than it would have taken me to do it with ice, and it looks messy. =\ At this point the car is looking raggy and like this;
Jan 09 - Feb 09
So the car was put on a diet, and I was happy with it at that point. So I decided that the old man and I would get started on the motor. I decided to go back with the KA (Whats and SR?), I have many laying around and evan more trannys so why not? So everything was sent off to the machine shops, and most of it was returned withing a few weeks.
Spent alot of time cleaning everything with soap and water, I cleaned everything for hours. I started with the crank shaft witch was polished, machine lightened, balanced, and knife edged. She was looking good! Almost didn't want to evan put it in the bottom end...
Next was the block, it got a major bath before assembly. One thing my dad always told me was the more you clean the better the motor will turn out. I cleaned it heavily and then mounted it up on the motor stand ready to rock! Block was machined, and is 40 over. Still needs new freeze plugs and to be painted a sexy color, not sure what yet...
Took a lil bit to get my rods back but Clemmons Speed Shop (NC) does some awesome work on everything hes every done for me over the years, so the wait was def. worth it. I decided to go back with stock rods because im not going to be hanging RPM's and the stockers are known to hold up. I just didn't see spending the money for EAGLES. The rods were shot peened, and are rocking ARP with Weisco 9:1 40 over pistons. (YUM!)
Once everything was cleaned and prepped I began assembly. Put down the Clevite bearings, and liad in the crank with no problems...
[NISSAN SPECS HERE]
Next step was to lay in the pistons. I needed to put the rings on, so I pulled out the Weisco spec sheet.
I was amazed at how thin the rings were, ive only seem OEM rings and these things are thin in comparison! But it was no problem putting them on, just be extra careful not to stretch them more than needed to get them on the piston's.
Now that all the pistons had rings installed, the only step left is drop those puppies in! But first I like to put a lil oil down in the cylinders. Makes everything smooth on crankup and when putting the pistons down in the block. Slip the piston ring compressor over the piston's and tighten it down snug. Before you drop the rod down the cylinder just be sure the crank out of the way of that cylinder so that when you put the rod down the cylinder the bolts don't scratch the crank. Just be aware of what your doing. Put the piston down on the block, and begin to tap the piston in slowly. Every time you tap the piston tap the ring compressor also in two different location, the main thing here is to not scratch the walls or hang a ring. (YIKES!)
Aight, now I flipped over the block, and pushed down the piston until I got it to where I could manipulate it so I could put on the bearings without it flopping all around scratching things. Put down some oil on the bearing and lay the bearing down on the rod. Now move the crank a lil bit to where you can finish pushing the piston down the cylinder and the bearing will ride up into the crank. Take a flat head and move the bearings until they are flat with the rod, most likely they didn't move, but just make sure the bearing hasn't shifted upward or slip down any. All that's left is to put another bearing on the rod caps and put then on the crank. Now put the bolts back on the way they come off the rod and torque down the rod bolts, now you can do the remaining three rods!
My main invester throwing up the approval, pops is killer!
Once your all done you'll get something like this... Looks good just needs to have the deck buzzed. All that was left at this point for me to do was wrap the motor up good and tight, and hide it in the garage until I get my head back from the machine shop.
