The 3.5L 240Z You Didn’t See Coming
Datsun, Reimagined

It’s 1969. You step out of your hotel, don your hat — yes, you wear a hat — and hail a heavy, box-shaped taxi. The interior is a bit dingy and unrefined, but you figure it’s that way so there’s less for passengers to make a mess of. It’s a dull experience, and while being driven you’re gazing out the window, wishing you were in literally any other car.

And that’s when you see it: a billboard for the all new Datsun 240Z. It’s yellow, with some sort of high-tech motion blur shooting off from the back. The low-slung body and the long swooping hood are indicative of something new; your automotive imagination is ignited.

The ancient taxi abruptly arrives at the office where you’re to have some meetings and talk about work, whatever that is to you. But your mind keeps going back to that car. Did you read that right? A Datsun? It looked more like an E-Type, or even the Toyota 2000GT.

Definitely not a Datsun, they just don’t do that…

But they did — the Datsun 240Z, a car so far ahead of its time. Today, in so many ways, the S30 still proves itself a timeless creation. Nearly 50 years after the inception of the Fairlady Z they’re more desirable than ever, and the aftermarket is still evolving.

2018-SH-Rebello-240Z-Trevor-Ryan_004

Nothing shows that more than Jeremy Gomez’s choice of motor for this build. I’ve always wanted to take an early 240Z and swap the drivetrain from a later 280ZX into the car, but Jeremy’s done me one better with a built 3.5L. But no, it’s not a late-model V6 from a 350Z.

2018-SH-Rebello-240Z-Trevor-Ryan_010

Jeremy put together another 240Z before this one; an LS-swapped handful of a car which, in his words, turned into a build that was just a bit too crazy. For the dozens of you who expressed your concerns in the comments section of that recent feature, this yellow Z should strike the right chord. It was built with a different mindset than Jeremy’s white creation, not as power hungry and properly Japanese.

2018-SH-Rebello-240Z-Trevor-Ryan_028

The white car was in progress before Jeremy started travelling to Japan and making friends at the car meets there, and the similarities and differences between the two builds are both obvious and awesome.

2018-SH-Rebello-240Z-Trevor-Ryan_025

One subtle touch along the back spoiler that I particularly liked is the mix of kanji and hiragana characters that read “Our Border Is The Horizon.” While it may not seem noteable, Jeremy’s friend in Japan has a similarly built 240Z with the same phrase along the back in English.

2018-SH-Rebello-240Z-Trevor-Ryan_008

I met Jeremy at his shop where I was pleased to find a number of old bits lying about. He’d spent his afternoon fiddling with a screwdriver to re-jet some cantankerous old carburetors, finishing up just minutes before I arrived.

Jeremy does high-end clear bras and the like, so for this Z he wrapped it himself when he was ready for a change. Around his workshop you’ll find dozens of little Z-car models along with the other 240 tucked in the back and an RB-swapped Nissan/Datsun wagon I took some photos of as well. He’s clearly a guy who loves modifying cars.

2018-SH-Rebello-240Z-Trevor-Ryan_012

After chatting a bit about the build, Jeremy’s old Corvettes, cars he’s passed on and the trips to Japan, we hit the road in search of a place to shoot.

2018-SH-Rebello-240Z-Trevor-Ryan_013

Hearing Jeremy put the throttle down brought a smile to my face, and I knew he had to be grinning too. The carbureted 3.5L straight six just sounds so good.

I know I can’t get away with making statements like this anymore without backing it up, so have a quick listen to the clip above.

Into The Forest
2018-SH-Rebello-240Z-Trevor-Ryan_014

After nestling ourselves into a patch of eucalyptus trees and admiring that nice long nose, I had to see exactly what was under the hood.

2018-SH-Rebello-240Z-Trevor-Ryan_015

Purists, there’s no trigger warning necessary this time. Go ahead and have a look; I promise nothing bad will happen.

2018-SH-Rebello-240Z-Trevor-Ryan_016

This is one of only a very small handful of these 3.5L motors in existence built by Rebello Racing, a highly respected (East) Bay Area shop that’s been doing quality work for over three decades. It’s based on the taller LD28 diesel block using a custom long-stroke billet crankshaft to bump displacement up to that massive 3.5L mark, despite what it says on top of the valve cover.

2018-SH-Rebello-240Z-Trevor-Ryan_017

I absolutely love the old Datsun straight six powerplant; with a trio of 45mm OER carburetors fed through a simple, highly functional yet attractive airbox, it’s hard to take your eyes off of the monster 3.5L.

2018-SH-Rebello-240Z-Trevor-Ryan_019

The motor looks so at home in the S30; it’s as if this was a high-end factory option back in the day.

The motor itself took over a year to complete, but as this was one of the first Rebello motors to actually find its way into one of these cars there were some complications. Jeremy pointed out that the left-hand side of the taller valve cover he chose for the already taller motor needed to be shaved down to clear the hood.

To handle the extra torque to the wheels, a SR20DET transmission was sourced along with an R180 differential from a Subaru Impreza WRX STI. The CV axles from the STI were also brought over, so it’s a setup that you can trust to last.

A Zstory exhaust turns spent fumes into beautiful music; if you glossed over the video sound clip, hop back up there and hear it for yourself.

2018-SH-Rebello-240Z-Trevor-Ryan_026

It’s a bit incredible, isn’t it? While I have love for just about any Z, this thing is just off the charts for me.

Reflecting On The Details
2018-SH-Rebello-240Z-Trevor-Ryan_042

Outside the motor is the extra long front end; it’s a Shoukai G-nose conversion that makes the car look as special as it is to drive.

2018-SH-Rebello-240Z-Trevor-Ryan_029

The quite long face of the car is complemented with ZG flares — which house SSR Longchamp XR4 wheels — and exaggerated by the low-down stance. BC coilovers have been used all around to lower the car while improving the handling.

Like Jeremy’s other 240, FutoFab tension control rods and ST sway bars help the thing stick to the road. Techno Toy Tuning LCAs in the rear keep the geometry happy. Also helping in the sticky department is a set of Toyo Proxes R888 tires mounted to the 15×9 and 15×10-inch wide SSRs.

2018-SH-Rebello-240Z-Trevor-Ryan_032

The more I looked at this car, the more I liked it — it’s a solid balance of extravagance and simplicity.

A Nardi steering wheel and Sparco seats replace their stock counterparts, but besides these items the interior remains relatively stock.

Jeremy says he has no plans to make the interior fancy, as he’s happy with where the car is now. If anything is going to change, he mentioned that he might go for an ITB setup to make that 3.5L even more insane.

2018-SH-Rebello-240Z-Trevor-Ryan_038

But for now, it’s a 240 he’s just flat-out enjoying. It’s a build that’s true to what a Z car should be, with heavy influence from overseas.

2018-SH-Rebello-240Z-Trevor-Ryan_039

You can tell it’s an absolute joy to be behind the wheel, and the car looks great at speed.

2018-SH-Rebello-240Z-Trevor-Ryan_040

While Jeremy certainly didn’t build the car with shows in mind it looks great parked up as well, whether viewed from the rear or over that long glorious Shoukai G-nose.

2018-SH-Rebello-240Z-Trevor-Ryan_041

The engine is the centerpiece, but all around, without a doubt, this is of the cleanest and most complete S30s I’ve ever seen stateside. More than this, Jeremy’s 240Z is a truly inspiring build that gives me faith that car culture will never die.

I expected a VQ35 swap. Still not disappointed.

2

VQ is crap..tired of that motor....glad they went with something different

3

I don't really think that VQ is crap, but I'd prefer this engine a lot more over the VQ if either one had to be swapped in.

4
Steffen Hansen

So much right in that car it's hard to say I miss the standard front.... Much wow, so car...

5

Oh, thank God.

I read the headline and feared the guy had dropped in a VQ.

Old Zs should only have straight-sixes - they're the only engines that fit the car's shape.

6

I feel like I'm the only one here who never liked this car with carbs. To me, idk, I like to bring classic cars to the modern era(ish), so really i would have liked this car with EFI tbh, but hey, it's still a crazy good sounding car.

7
Patrick Peebles

It's funny you should say that. I actually just got done converting my EFI 280z to carburetors. I have to say, I like the carbs sooo much more than the old EFI system.

8

Flatslides by any chance? ( :

9
Patrick Peebles

I wish... SU's for now. Designing a six carb manifold right now though.

10

Both of Jeremy's Z's are very nice and I appreciate his style and choices as his own. I do however truly enjoy the look a Datsun 6 has in the Z car engine bay, fills it so perfectly.
Great work Jeremy, and nice finds Trevor!

11

i'm sure the owner enjoys spinning this around here and there.

12

Datsun 320Z!

13

You mean 3.50z? :)

14
Sean Dézart (Zstory)

Thanks Jeremy - she turned out pretty well ;-) !

15

I can't really find much wrong with this car, so I'll just say it's too low and I don't like stretched tires. With that fitment, does the suspension really have enough room to work without leaning on the bump stops?

16

please shut the fuck up. this is one of the best cars I've seen shared on this site in recent months

17

I think the comment section exists for us to share our opinions here. Take a chill pill soldier

18

"If you don't have the same opinion as me your opinion is wrong, invalid and should never be shared, ever"

19

Really well done, great build, love these Z's no matter what's under the hood. It's a symphony of goodness but the only off note for me is chrome rear bumper; might fit the theme better in black. No matter, big thumbs up!

20

"this is of the cleanest and most complete S30s I’ve ever seen stateside"
missing a word in here, Trevor.
and ps....black/non-body color engine bays = you need to define "cleanest and most complete S30"

21

Happy to help speedhunters. And been waiting on this feature. Best pics I have seen from you so far Trevor

And Jeremy you know wassup

22

Nice touch with the number plate.

23
Dino Dalle Carbonare

Love this!

24

Does any one know what those rims are because I've been searching for so long and the only name I've gotten is 'LONGCHAMPS' but I' not sure.

25

just read deeper into the article they are ssr longchamps

26

The not too much is what makes this car good: simple flares, nice color, simple interior, suitable engine,.....
I'm a big fan of big single tips exhausts (specially the rounded tips) so that would be my only minor point to this build, in case the exhaust sound will not be affected.

27

The factory S30 had a vertical mounted twin tip muffler in this style, which is kind of unique. so you see a lot of the aftermarket systems keeping that touch. Single tips also look good though

28

Great car! Love the color, the ENGINE and the interior. Car sits too low, tire stretch is a bit much and the wheels need black in the centers. The chrome / aluminum long champs don't match the rest of the car. Also, should powder coat the valve cover black or chrome.

29

That's like, just your opinion man.

30

I seen it comming, I seen it in the (coming soon) featured images before it was released and in the youtube video before I read this post.

31

Nice to see a period correct swap with a later model straight six. And the carbs, oh yeah the carbs. That thing sounds great!

32

Quite the stunner! And the engine sound mmmmmm....

33

As a writer myself I have a lot of respect for your style. That opening paragraph was simple and really pulled the reader in. Like your stuff a lot Trevor! Can't go wrong with a black and yellow 240Z either...

34

This is probably the cleanest Dastun S30s in a long time on this website, and it looks absolutely stunning in that yellow; it really makes the car pop.

35

So this Rebello engine is actually using the LD28 block in its entirety? Classically the diesel-based stroker engines all used that crank with a combination of stuff in a gasoline block. That valve cover is a nice touch, very clean build.

36

Probably the best looking and sounding 240Z I've ever seen

37

After reading it wasn't a V6 I was guessing an RB30 based engine so an L-series was a nice surprise

38

Love this, I have gone back to this article 4 times just to admire this Z

39

Beautiful Z. What is the power output of the engine? Call me wiskers, I'm curious like the yellow cat!

40

I'm guessing 250 to 300 HP. the 45mm carbs are going to be the limiting factor.

41

On the technical end, when you say he's going to ITB's you should say EFI ITB's because these are ITB carbs.

42

Holy fuck, that 3.5L does exist! Saw a picture of Rebello working on it years back. What’re the numbers on this demon?

43

You gotta be a real S30 head to appreciate this build. From the twin stack exhaust to the 4spd knob even though it’s a 5spd!

44

Thanks for the vid it was very crispy ;-)

45

Quality build throughout. A few things that I would do differently, but hey, I didn't pay the bills! Would be interesting to see how the 3.5ltr compares power wise to the engine (built by Les Collins Racing) in the "Green Hornet".

46

I have a soft spot for these cars....

47

Absolutely lovely!!!
