Balancing Act: A K24 & DCT-Swapped Silvia S13

Stability. It’s vital in so many facets of life, regardless of the context. 

It’s one thing which Tom Lingard’s 1993 Nissan Silvia definitely brings to the desk, particularly when in comparison with the again catalogue of S-chassis builds through the years. That could be a divisive assertion, however bear with me as I delve into some of the outstanding all-round builds I’ve had the pleasure of that includes over the previous few years.

Tom isn’t any stranger to the Speedhunters; I featured his earlier construct, a 1981 Datsun Sunny Truck, the day earlier than he bought it again in 2021. This was a Honda K20/24 Frankenstein monster-powered train in ‘why not?’

“The Datsun construct that preceded the PS was a tiring two and a half years of laborious graft, which paid off for essentially the most half, however left a few bins un-ticked,” says Tom.A PS13 had been excessive on the ‘achievable’ bucket checklist for a very long time, and I felt it was lastly time to do it after the Datsun.”

Now simply between us, I like to save lots of the perfect for final when writing an article. The USP, the large climax, the primary purpose for the function itself is without doubt one of the final issues I’ll go into element about. I’m going to make an exception for this automotive. It’s already been revealed within the title (and on the Silvia’s licence plate), so get pleasure from dessert first right this moment.

“The automotive was purchased with a transparent imaginative and prescient set out: K24 turbo (I actually missed having a turbo) and the all-important DCT conversion,” says Tom.

Sure, if it wasn’t already clear, Tom’s Nissan Silvia is powered by a turbocharged Honda K24, channeling energy to the rear wheels through a BMW M dual-clutch transmission. The perfect candidate to start out with? A quite uncommon and quite fairly Aztec Pink instance of Nissan’s now iconic sports activities coupé.

“I collected the recent import in October 2021 per week earlier than I used to be away for the remainder of the 12 months,” say Tom. “In these months, I ordered nearly every thing I wanted for the construct and despatched off what I wanted to get the automotive a UK registration.”

Not one to waste time, Tom made positive he was able to crack on upon his return from abroad. And after I imply crack on, I imply with every thing. Himself.

“Within the time I might have been within the storage working, I accomplished the Excessive Efficiency Academy tuning course since this [engine tuning] was one of many final issues I used to be nonetheless counting on others for.”

What lies within the arch-tubbed engine bay is constructed on a Darton-sleeved K24 backside finish, with a K20Z4 cylinder head secured by ARP head studs and a Cometic head gasket. Pull the block aside and also you’ll discover Boostline solid connecting rods with ACL bearings, plus Wiseco solid pistons to obtain a ten.2:1 compression ratio. A ported K20 oil pump ensures ample lubrication, whereas a TF Works oil pan sits on the backside of the engine.

The top has acquired an equally complete overhaul, now residence to CPL Racing valve guides, and Clockwise Movement beehive valve springs and retainers. To deal with the enhance stress, Tom fitted hardened Supertech nitrided consumption valves and Inconel exhaust valves. Inconel is, as everyone knows, a superalloy. The phrase ‘superalloy’ makes me really feel issues.

Simply how a lot enhance stress? Effectively, in the mean time the tune continues to be set as much as run a Garrett G30-770 turbo, although a Garrett G30-900 is bolted to the engine via a customized exhaust manifold. As such, 22psi of enhance is the present determine, producing 615hp on Tom’s personal tuning map. A bit of dyno time and Tom will tweak his tune to profit from the 62mm G30-900, the place he’s aiming for a conservative and dependable 750hp.

The Garrett is complemented by a Turbosmart 40psi oil stress regulator, TiAL 60mm wastegate with screamer pipe, customized 3-inch down-pipe and high-clearance oval exhaust tubing making its strategy to a single again field. Administration is through a Haltech Elite 1500 ECU and CAN wideband.

Air circulation and fuelling is taken care of by a Ok-Powered consumption manifold, 74mm Bosch drive-by-wire throttle physique, Radium gasoline rail/gasoline stress regulator and ID1700X Injector Dynamics injectors.

I don’t possess the endurance to say the quite a few sensors Tom has built-in into his work, monitoring nearly each security side attainable. I’ll point out the customized oil catch with AN10 fittings and the customized solid carbon radiator shroud, as a result of they’re fairly.

The cooling system in Tom’s Silvia is absolutely trick, and part of the construct he’s quite pleased with. “I spent a lot of time right here this winter after having cooling points the primary summer time driving the automotive. I re-packaged all of the radiators stacked on prime of one another in order that they could possibly be totally sealed, and downsized the thickness of the intercooler to advertise circulation. I discovered a greater sized OEM air-conditioning condenser to optimise air circulation and permit for good ducting,” he says.

“As soon as that was achieved, I had the entrance finish of the automotive 3D-scanned and started working designing ducting from the bumper inlets into the coolers, and a fan shroud for the radiator. These have been then 3D-printed and used to make moulds for the ultimate components to be made in carbon fibre. After testing, I’ve seen a giant enchancment.”

The ultimate consequence consists of customized 3-inch aluminium intercooler piping with quick-release couplers to a 300x600mm intercooler, fed via 3D-printed bulkhead seals. A Koyorad dual-pass radiator with customized laborious traces is run through bleed factors to the growth tank, fixing the pretty widespread concern of Ok-series engines being laborious to bleed.

Energy to the rear wheels runs although the aforementioned BMW M DCT gearbox, which runs a customized oil cooler and billet sump. The driveline additionally options an AdamMT dual-mass flywheel, customized prop shaft, and a 4.1 ratio Tomei 2-way limited-slip differential in a Nissan 350Z rear finish.

Tom was adamant that his Nissan needed to retain air con for summer time drives, and he managed precisely that with a neat little setup. A Fiat 1.9 TDi condenser is joined to the OEM Nissan evaporator through customized laborious traces, with Tom even managing to wire the OEM Nissan digital local weather management to speak with the Haltech ECU.

“The engine bay is stone chip coated with a physique color base and clear-coat excessive. When you ignore the oldsters doubting DCT or Ok-swaps, that is the ‘Marmite’ a part of the construct,” says Tom. “Most individuals appear to get it, however some don’t. The rationale for this resolution is it’s a lot simpler to prep for, hides some sins, seals seams and it’s a lot simpler to restore scratches vs. regular flat paint. Since this engine bay goes to see spannering typically and the unintentional scratches that include it, this was vital to me.”

Air-conditioning apart, the inside of the Silvia is a pleasing place to be. Take the wi-fi double-DIN head unit with Android Auto, or the 3D-printed cupholders instead of the guide shifter. In his quest for drivability, Tom has retained a full inside. NVH is the enemy, in any case.

A pair of suede Buddyclub P1 Redline Version seats elevate the cabin, as does the black-dyed carpet, headlining, rear bench and cloth trims. The suede-trimmed door playing cards and glovebox match the seats, in addition to the suede Private 330mm steering wheel. Tom even went to the extent of sourcing a crack-free dashboard, uncommon for an S13.

A Haltech IC-7 digital sprint sits behind the wheel, with Tom’s personal graphics tweak. Word the little TL (Tom Lingard) Spec brand within the rev counter.

The steering wheel-mounted management panel is my favorite element of the construct. Buttons for cruise management, launch management, rolling anti-lag and a horn sit alongside 12-step rotary switches for traction management and enhance settings. Distant paddle shifters for the DCT are managed by a wi-fi transmitter on the again of the center spoke.

Relatively amusingly, with the automotive operating Tom may even function the horn with the wheel in his fingers.

Even the boot didn’t escape the TL Spec contact, now housing the battery, surge tank and a customized false flooring divider, permitting for under-boot instrument and automotive cleansing storage.

The Silvia’s exterior is a shining instance of simple-is-best. An Origin Labo Stream Line physique equipment provides depth and aggression to the dainty Silvia, with an identical boot lip spoiler too.

Being a ’90s automotive, particulars such because the crystal clear headlights, indicators and ‘grille’ with no yellowing are appreciated. So too are the little mirrors, which at all times have a spot in my coronary heart.

18×9-inch and 18×9.5-inch staggered Enkei RPF1s fill the arches, with 235/40 and 245/40 Nankang AR-1 tyres entrance and rear, respectively. The fitment is bang on, a mix of low experience peak and practical tyre sizes. BC coilovers paired with Driftworks entrance and rear arms present most adjustability.

Contained behind the RPF1s are PB Brakes 8-piston entrance callipers and 6-piston rears with 356mm floating discs all spherical and the hand brake built-in into the rear drums.

The underside of the Silvia has had a full restoration. Fabricated components have been powder-coated; solid and aluminium elements have been anodised in black; fittings are plated in yellow zinc. Alongside subframe reinforcements and a set of customized jacking factors for simple lifting, the ground has been stripped, stone chip coated and completed in black chassis enamel.

In the case of vehicles, stability is much too typically neglected today. Homeowners the world over attempt to construct the wildest and rowdiest vehicles they will, solely to face out from the gang. The bottom, the quickest, essentially the most highly effective… the checklist goes on and on.

Builds like Tom’s Silvia don’t shout the loudest or declare any titles, but typically find yourself being among the finest. I feel this one could also be simply that, ‘the perfect’, don’t you?
