1/71 #18720 a.k.a. Sakura

Recommended Posts

Posted (edited)

I originally purchased this "Series 1" that I have named Sakura in an attempt to flip it. Plans changed quickly after I wrecked my 3rd owner 73 240z last year. So far I have owned this 1971 240z for a little over a year. I moved cross country at the end of last year so I have only really been working on her since the quarantine.

The car was mostly original upon purchase. Missing radio, but all other Series 1 parts are present minus steelies and hubcaps. Very solid rustwise. Solid floors, framerails, battery tray area, hatch area. Original color is 901 silver; the car has had one hasty black respray over original paint. I found some bondo in the front fenders; these will be replaced with OEM before paint work back to original color.

The worst part about the car: the PO riveted cheap fiberglass flares on uncut wheel wells (more on that later). My choice was to save the wheel wells and keep a mostly stock body.

The car was very well maintained mechanically over the years. Matching numbers L24/E31. All I know about the car is that I bought it from a flipper in Denver who never finished the respray. Daily driver quality. Accel coil, round top SUs, stock exhaust. Solid steering, decent brakes, weak clutch but good transmission. I have put about 600 miles on the car with no breakdowns.

280z vented hood and a Chinese HID kit. I'm going to keep it for now. I have stock vents that need to be painted.

I immediately added new NGK wires and the correct Series 1 airbox.

Here in Indiana I started gathering parts and stripping her down. The stock seats were sold for $100 locally and I will be replacing them with period correct Recaros from MCK Recaro.

I sold my 73 240z locally for $3800 and kept the 4000-mile L29, triple Mikuni 44 setup, and Fujitsubo exhaust. This is just the beginning of parts I started to acquire Feb-March 2020.

The first part of the teardown was the front suspension. I will also be using Arizona Z Car steering knuckles and replacing as many parts as I can. All suspension and drivetrain components will be new or rebuilt.

The car was undercoated in the past and it preserved the undercarriage fairly well. Here you can see the original silver paint. The steering rack was much easier to remove than I thought.

Sway bars will be replaced with ST front and rear, 25mm/19mm with Energy poly bushings and NOS NISMO poly endlink bushings.

Nowadays I am prepping the suspension components and engine bay. I'm sandblasting the suspension components and they will be painted with Master Series products: Mastercoat and the AG111 Top Coat.

I also hired a mobile welder to weld in sway bar reinforcement plates. He did a great job.

Wow, you work quick! ?

Love the wheel choice for the look you're going for. Tell us about the engine build plans.

The engine is from my wrecked 1973 with approximately 4000 miles on it. Bored 10.0:1 F54 L28, polished crank, $1100 port job on the E88 head, oversize stainless steel valves, Schneider "Stage 3" cam kit with "10k rpm springs." Paired with SUs, Clifford Research 6-2 header, and 2.5" exhaust, the engine dynoed at 129 rwhp/ 140 rwtq at 6000 ft altitude which translates to about 160 hp/tq at sea level. My timing was off and the shop wouldn't let me make any adjustments. The SUs ran out of air at 6300rpms at elevation.

Now I'm rocking Datsun Competition Mikuni 44s and a Fujitsubo stainless 48mm primary 6-2 header and twin 60mm pipe exhaust.

Next on the performance block will be a one-off cam from Steve Bonk originally ground for the new John Morton car. He wouldn't tell me the specs until I paid! Great guy.

Here's a photo of the motor in my 73.

That's pretty high up there in RPM.  Curious about the hp/tq?  Usually they're reported separately.  Which is which?  And where/when?  The curves would be nice to see.

This dyno sheet is from 2018 at RPM Performance in Colorado Springs, CO. I edited the numbers. The cam was a lot weaker than I expected. Also my Mikunis and timing are dialed in much further than my previous setup.
