Z31 N/A RB project

    Recommended Posts

    I ordered Ichiban 5 lug hubs/bearings as well.

    I assume you meant Ichiba parts. Have you read the reviews on Ichiba parts? I have a healthy fear of their manufacturing quality control. Many people in the 370 and 350 world have had issues with their parts.

    Unfortunately he said it's a lot more work than we originally expected but he said it won't be a problem. 

    It always is! :blush:

    Amen to that!

    The original DIY thread on this used photo bucket for all the photos and of course they are all gone now. It said to modify the rear mounts that the guy made to be used up front but didn't really elaborate on how. Just suggested "do the best you can". My friend decided he didn't like that plan and so he is cutting the front ears off the Z31 subframe and welding them onto the S14 so the stock locations can be used up front. The rear side to side bar in the chassis out back is the perfect location for the guys mounts. This should be a really good way to achieve this swap and I can't wait to get updated photos. He plans to have it done and back to me tomorrow. Amazing to see how much better the S14 subframe is compared to the Z31.

    I can't wait! Too bad I didn't get more seat time as while it was stock. I think I put all of about 12 miles on it before it was torn down ROFL

     

    Ordered the Nitto stroker 2.8L crank, H beam rods and upgraded rod bolts. Also ordered a stainless RB26 exhaust manifold flange since my headers are from the RB25 which oddly enough, has a slightly different bolt pattern. Now I can drop the block and crank off with the machinist and get in line so that by the time he is ready to start that, the custom piston specs will be ready. He can also port match the header flange while doing all the headwork. 

    The throttle bodies are done. Enlarged to 49mm, new butterflies, seals, bearings and re-plating of all the hardware. They are assembling the linkage and shipping back from Australia next week.

    Enjuku racing RB Z31 oil pan arrived and the traction rods for the rear suspension are supposed to ship tomorrow. Then it will go to a local shop for the rear cage next week. Going for this design only with much better welds and no diagonal bars down to the trans tunnel. 

    Lastly, I am having the stock intercooler recess on the valve cover welded up to mirror the other side. It's always bothered the hell out of me on RB's.

    This is so cool! I have never seen this done but always hated the stock intercooler notch on the RB26 valve cover. The body guy made an aluminum cover and welded it in place.

    Flat medium wrinkle grey. Similar to the S20 engines in the original 432 and GTR. Most people do black or red but I think the grey will be more suited for this one and will contrast the color well. The trim, spoilers, roll cage and wheels will also all be gunmetal to tie in the theme. 

    In my daily searches I stumbled upon this while looking for JDM lights which is the craziest part I have ever seen for the Z31. It's for an 86 and has a 10k redline vs the original 8k. It's like it was meant for this project! I also love the tricolor display for tach and speed as well as the nifty sub 1/4 tank detail gauge like my old 87 Pathfinder had. Totally 80's, totally rad! I was racking my brain on what to do about the tach because I wanted to keep the factory cluster but also wanted to know my correct revs. I was planning on going with a digital display but now I can keep it old school.

    Yeah, can't change that. Would be just as if it were a JDM. I will just have to familiarize myself with where 80 is ;)

    Unfortunately that cluster was sold but never removed from the site. Bummed because that was a fantastic find and I got an order confirm and everything. Seems the site has a number of things listed that are no longer available. I found a few companies that might be able to replicate it though. 

    Got the throttle bodies back. Enlarged to 49mm, new plates, seals, bearings, bore coating and all hardware plated in yellow cadmium. Watanabe's are done and ship tomorrow! Cannot wait to see them! Stroker crank, rods, header flange and head studs arrive this week too so I can run it all over to the machinist. Then the real fun begins! Also, a few more shots of the amazing work done on the RB26 covers. Lastly, spray outs of Lotus saffron yellow and Nissan safari gold. Saffron is out but I am going to take a loot at Porsche 139 blossom yellow or blood yellow as it's sometimes referred too. It was a common color on the 914 back in the 70's and appears to be like 920 safari gold with a touch more yellow. It's also the color of RUF's "yellowbird". I am most likely to paint it safari gold but I definitely want to see the 139 color before I make the final call. 

    Lastly, the traction rods shipped and once I get them in, the car can be towed to the fabricator who is doing the rear roll cage. Then on to bodywork and paint!

    Gotta hate that on the cluster!

    Yellow bird. I remember when the car was new. What a beast! Good color...

    Whoever did the valve cover has good metal skills!

    Thanks and yeah, the metal guy is amazing!

     

    The Nitto stroker 2.8L crank, H beam rods, ROSS crank fire hall sensor kit, ARP head studs, ARP rod bolts and the RB26 exhaust flange arrived. My traction rods showed up as well so I can get those in and tow the car to the shop that's doing the rear cage on Sunday.

    Traction arms in and the car is finally brought down. Hilarious how high the front is compared to the rear. Ready for takeoff!

    I've spent hours researching tires and running tire calculator numbers to figure out the ideal tire for my application and finally made that difficult choice. It was down to about 10 including several track only tires but I spoke with some people with real street experience who say the only issue with that is excessive gravel, noise and stiff sidewall. That led me to extreme high performance summer, narrowing it down to about 5-6. In the end, I focused on the tried and true Bridgestone Potenza RE71R which seems to be the absolute best R street compound affordable tire you can get. A close runner up was always the Dunlop Direzza ZII. It came close to the grip of the RE71R but it also far exceeded the tread life as well as lowering road noise. Then rumors circulated of it's replacement, the ZIII as a direct challenger to the RE71R. They were just released and were only $10 more so I went ahead and ordered 2 225/50/16's to test fit on the Watanabe 18x8/8.5. They claim equal or better performance to the Bridgestone with almost double the tread life and less road noise/harshness. They look almost identical as well. Coming from BMW for the last 10 years, I welcome the cheap prices of a 16" tire! 

    The car looks great with the drop! Off tomorrow for rear cage! That will be exciting.
