Home Grown: The Chasing Js 240Z
Chasing A Dream

As someone who considers himself seriously lacking in the DIY and skilled crafts department, I have open admiration for those who are able to hand craft things themselves.

The determination to tackle something that you’ve never done before, simply by enrolling in the School of YouTube and absorbing enough information until you feel empowered and informed enough to just throw caution to the wind and give it a go, is a pretty cool quality if you ask me.

The 240Z in front of you has been in Dominic Le’s possession for just over a year now, but some of you may recognise it from its debut at the 2017 SEMA Show back in November. The aim was to reimagine a classic with some modern touches, but without any unnecessary bells and whistles; just a raw, clean car that would turn heads and could be driven hard.

Larry_Chen_2017_Speedhunters_Chasing_Js_S30_027

Dominic ultimately wanted to push the limits of what he could build at home. That’s right – pretty much everything here has been done by Dominic and his friends over the course of six months. He’s entirely self-taught at this, too.

Larry_Chen_2017_Speedhunters_Chasing_Js_S30_005

Some jobs, like the titanium welding and the paint were outsourced, but Dominic did as much as he could up to that point. Building the 240Z was as much a learning experience as it was a means to an end.

On the surface, the exterior appears a reasonably simple recipe. Building upon the Z’s classic shape, the addition of Datsun ZG flares bulks up its road presence, whilst giving the wide Work wheels much needed breathing space.

A custom pair of Chasing Js red reflection carbon fibre front and rear bumpers, and front splitter were added – the red is woven into the composite, giving it a near black appearance that reflects hues of crimson.

Other small details, like the carbon fibre door handles, OEM fender mirrors, and JDM rear lights add the finishing touches.

Larry_Chen_2017_Speedhunters_Chasing_Js_S30_016

The whole lot is coated in a deep PPG red. I think Larry’s done a pretty good job here of conveying how the light and shadow plays with the paint.

Larry_Chen_2017_Speedhunters_Chasing_Js_S30_028

The Z is brought down to the ground by a set of custom 32-way adjustable coilovers with Swift springs. Techno Toy Tuning front and rear lower control arms and MSA sway bars offer additional control and adjustability.

Larry_Chen_2017_Speedhunters_Chasing_Js_S30_009

Its unfortunate that all of the hard work underneath the chassis will never be seen as Dominic stripped down every nut, bolt and component to bare metal, before either restoring it or replacing it with an upgraded component.

Larry_Chen_2017_Speedhunters_Chasing_Js_S30_029

At the back, a T3 moustache bar and R180 Subaru STI differential along with Porsche 930 chromoly CV axles help put the power down.

Larry_Chen_2017_Speedhunters_Chasing_Js_S30_013

At each corner sits a gorgeous custom Work Equip 40 finished in a one-off bronze barrel and face combo, wrapped in Toyo Proxes R888R rubber. The wheels are the perfect colour to complement the paintwork.

The fronts measure in at 15×10-inches, while the rears are 15×11-inches.

Larry_Chen_2017_Speedhunters_Chasing_Js_S30_042

The interior is both raw and luxurious. A juxtaposition in terms, but the exposed metal work, coated in the same PPG red paint as the exterior, mixed with lashings of shiny carbon fibre and touches of titanium shows that lightweight doesn’t have to mean bare bones.

Larry_Chen_2017_Speedhunters_Chasing_Js_S30_041

The dashboard, door panels, centre console and tunnel are all made from the lightweight composite, and the whole lot together weighs in at under 51lbs (~23kg). Compared to the Z’s stock seats which weigh 60+lbs (~27+kg) each, that’s a significant weight saving.

Larry_Chen_2017_Speedhunters_Chasing_Js_S30_040

The replacement seats are completely custom carbon items, retrimmed in black leather and adorned with Takata Racing harnesses. A custom rear half cage and Chasing Js rear strut bar helps add to the chassis’ rigidity.

Larry_Chen_2017_Speedhunters_Chasing_Js_S30_044

Strap in and peer through the Renown USA wheel and a RacePak IQ3S digital dash flashes to life in front of you. The titanium short shifter is an ATP item of Dominic’s design, and despite its height, reduces the throw significantly.

There’s not much in here to accompany you, but everything around you is made from the lightest, highest quality materials. The result is a kerb weight under the 2,000lb (~900kg) mark.

Larry_Chen_2017_Speedhunters_Chasing_Js_S30_025

When it came to the power plant, rather than increase capacity, Dominic opted for a smaller engine with two less cylinders than the S30 came with as stock.

Larry_Chen_2017_Speedhunters_Chasing_Js_S30_020

Long gone is the six-cylinder L24, replaced by the popular four-cylinder SR20DET from a JDM import Nissan S13. The SR20 often comes under fire from those who like to get busy with their keyboards online, but it’s a proven motor that Dominic is familiar with. There’s a huge aftermarket support and it can make really good power with relatively little trouble.

Larry_Chen_2017_Speedhunters_Chasing_Js_S30_019

Dominic was keen to keep the weight central in the car, so using the strut towers as an imaginary border, positioned the newer, shorter engine as far back as he could.

Larry_Chen_2017_Speedhunters_Chasing_Js_S30_018

In completely stock form the SR20 would present a nice 50hp or so jump over the L24, but as you’ve probably guessed going by the rest of this build and these images, Dominic wasn’t about to leave things stock. The Nissan block has been ported and polished and is adorned with forged CP pistons, Manley connecting rods, ACL race bearings, a knife-edge counterweighted crankshaft, full Supertech valvetrain, and Tomei lifters and cams.

Larry_Chen_2017_Speedhunters_Chasing_Js_S30_024

Air is sucked through an Apex Performance custom Garrett GTX3071R turbo and into a GReddy intake manifold, only to be expertly contained by a GReddy metal head gasket. Fuelling is courtesy of ID1000 injectors, Nuke Performance FPR and Radium Auto fuel rail, while a CSF triple-pass radiator helps keep things cool under the collar.

Larry_Chen_2017_Speedhunters_Chasing_Js_S30_021

If you hadn’t guessed already, Dominic has a bit of a penchant for titanium, too. Every piece of piping in the engine bay has been crafted, by Dominic, from the coveted lightweight material, as is the custom intercooler shroud. Where possible, every nut and bolt is titanium. The strut bar was absent at the time of Larry’s shoot but… you guessed it… it’s made from titanium, too.

Larry_Chen_2017_Speedhunters_Chasing_Js_S30_010

Tuned SR20s are nothing new in this day and age, but there’s some clever forward-thinking and technology that’s gone into Dominic’s build that sets it apart from the rest. For a start, there’s no throttle cable – the engine has been converted to drive-by-wire thanks to a Toyota GT86 throttle body, port-matched to the GReddy intake. Amusingly, Toyota Prius smart coils with built-in igniters have been utilised too. Even more surprisingly, these are good for up to 1,000hp in this application. Talk about over-engineered OEM parts?

Larry_Chen_2017_Speedhunters_Chasing_Js_S30_030

The fancy new tech plays nicely with everything else thanks to a custom Rywire mil-spec wiring harness and Adaptronic M2000 ECU. The result is a modern and sophisticated engine management system that helps propel the 240Z’s SR powerplant to the tune of 428whp. Add that number to the kerb weight from earlier and the results are lively, to say the least.

Larry_Chen_2017_Speedhunters_Chasing_Js_S30_003

What’s perhaps most impressive about this build is that Dominic’s 240Z wasn’t prepared in a big shop by a company or large team of staff.

Larry_Chen_2017_Speedhunters_Chasing_Js_S30_004

It’s a setting that completely belies the quality of work that has gone into this car. It’s a build that’s fuelled by passion and attention to detail above all else.

Larry_Chen_2017_Speedhunters_Chasing_Js_S30_039

Build done, Dominic’s favourite part about his 240Z is finally getting to drive it: “I have been building cars every year and up to now haven’t really gotten a chance to enjoy the fruits of my labour,” he says. “I just want to get out and drive the car hard, and if things break, well, I’ll just fix them and break them again until we get it right.”

It's a stunning car, no denying that.
But... "No bells and whistles"? Yeah, digital dash, modern swap, titanium this, titanium that... Riiight ;)
And I seriously hope this will not be another trailer queen, cause it would be such a shame to waste all those nice, overengineered parts on something that would be driven from one cars & coffee to another.
But, once again, a truly beautiful automobile! I think I will always have a soft spot for those old Z's.

Author2

I mean – dash readout, reliable powerplant, floorplates, etc. It's all just the basic stuff that makes a car a car, but make really well out of nice materials. I think what Dominic was referring to is the unnecessary parts that don't add to the driving experience – all that stuff does.

3

A very tasteful and superbly executed build. Saw this on Jay Leno's Garage, and God I wish this was for sale!! Kudos to Larry for the awesome photos, specially the ones with the shadows! Jordan did a fine job with explaining how the modern tech entwines with the proven SR20. And a 1000HP Prius sounds like my next build!!!

4

Thanks Michael!

5

I've been following this car/owner on IG and it's great to see a more thorough review on one of the best S30's out there right now. All business with the focus on driver experience.

6

Really digging those red carbon fibre bits!
I know I've said this before on an older article, but I'll say it again: Even though the 240Z was a couple decades before my time, nonetheless it's a car I've really fallen in love with.

7

It really is an amazingly timeless shape.

8

Haven't really seen a red S30 before, but now after seeing it, I think I might need a new pair of pants. So good looking. Also is this a pure race car, explaining the stripped interior?

9

I too followed the build on IG and saw the car at SEMA. I like everything about it and imho it.s the right amount of show/go. Two things are nagging me:
1) WHY the Renown steering wheel? Every part on the car is name brand/high quality and not a knockoff. Why not just get a real MOMO Prototipo? You can even make you own custom wheel with MOMO to suit your stitching/wrapping desires.
2) That glossy dash must reflect crazy light!

10

Renown isn't knockoff and is very good quality. great wheels made by an enthusiast.

11

Are you sure?
Look at the MOMO Prototipo and Renown "Monaco"
Quality? Renown wheels are made in China.

Brennan McKissick

Wow, this is an extremely well done S30, first time builder and DIYer or not.

13

Really, really love this car. Such a focused, well-planned and well-executed build. I think the SR20 was the perfect engine choice, lowering the cylinder count is right in line with the weight loss goal. It seems he and I have similar philosophies for how we want our cars to be, and now more than usual I want to duck out of work early to get back to work on my own project. Great article!

14

first off...it's spelled curb, not kerb. and is it really that surprising that someone built a car at home? there are countless examples of cars at this level and well beyond that are home built. that is such a stupid marketing ploy to chase after....the car itself is nice. the splitter rods are completely stupid, pointless, out of place and uneven tho. and the digital dash seems like an after thought to cover up the horrible carbon work inside the gauge bezel of the dash. also looks terribly out of place. overall its a nice, albeit a completley by the numbers Z build... with some titanium, trendy/stupid splitter rods and 3d printing

JBfromSiliconValley

I bet you're a ton of fun at parties.

16

Kerb is the British spelling.

17

Sh staff can't win continues. People gripe about cars built by shops with endless budgets AND home built cars.

Bizzare.

18

First off, in England, where we invented English, it’s called kerb.

Secondly, have you heard yourself?!

19

I am not familiar with port and polishing an engine block. A cylinder head/heads, I know. How was this done? Sorry to ask.

20

Was it the oil galleys?

21

Were you referring to a larger cylinder bore?

22

i want to drive her ^ ^

23
Matthew Everingham

:O

24

Good choice for a swap tbh. SR is probably hundreds of pounds lighter than a 2JZ. Very proven platform and lighter than the L28. Given the weight the car is probably a lot of fun.

25

The red carbon touches are a treat. If it were mine I'd tweak a few bits but overall super well put together.

Looks like a fun drive too.

26

Man, credits where credit is due. Dominic, this car is bizarre good looking! Simply superb car. This motivates me to do the same, but on a smaller scale. Just need a house with a garage and a nice project car.

27
Massimo Reggianini

Is this need for speed payback? :D Stunning car and enviroment!

28

Love this car! My dad had a 79 280zx when I was small. Loved the z ever since. Like that a lot if the work was done by the owner. Love the small details like the side lower frame by the seats with the circular cut outs. Makes me want to get my lazy ass up and get to pulling apart my project...

29

That front splitter is the only glaring ugly piece. That was way early 2000s and takes away form otherwise a nice car.
