Balancing Act: A K24 & DCT-Swapped Silvia S13


Stability. It’s vital in so many points 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 over time. That could be a divisive assertion, however bear with me as I delve into one of the vital exceptional 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 offered 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 exhausting graft, which paid off for probably the most half, however left a few bins un-ticked,” says Tom.A PS13 had been excessive on the ‘achievable’ bucket record 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 avoid wasting one of the best for final when writing an article. The USP, the large climax, the primary purpose for the characteristic itself is likely one of the final issues I’ll go into element about. I’m going to make an exception for this automobile. It’s already been revealed within the title (and on the Silvia’s licence plate), so take pleasure in dessert first at present.

“The automobile 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 slightly uncommon and slightly fairly Aztec Crimson instance of Nissan’s now iconic sports activities coupé.

“I collected the recent import in October 2021 every week earlier than I used to be away for the remainder of the yr,” say Tom. “In these months, I ordered virtually all the pieces I wanted for the construct and despatched off what I wanted to get the automobile 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 all the pieces. 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 cast connecting rods with ACL bearings, plus Wiseco cast pistons to obtain a ten.2:1 compression ratio. A ported K20 oil pump ensures adequate lubrication, whereas a TF Works oil pan sits on the backside of the engine.

The pinnacle 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? Nicely, in the mean time the tune remains to be set as much as run a Garrett G30-770 turbo, despite the fact that a Garrett G30-900 is bolted to the engine by way of 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 technique to a single again field. Administration is through a Haltech Elite 1500 ECU and CAN wideband.

Air circulate and fuelling is taken care of by a Okay-Powered consumption manifold, 74mm Bosch drive-by-wire throttle physique, Radium gas rail/gas 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 virtually each security side attainable. I’ll point out the customized oil catch with AN10 fittings and the customized cast carbon radiator shroud, as a result of they’re fairly.

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

“As soon as that was executed, I had the entrance finish of the automobile 3D-scanned and set to work 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 end result consists of customized 3-inch aluminium intercooler piping with quick-release couplers to a 300x600mm intercooler, fed by way of 3D-printed bulkhead seals. A Koyorad dual-pass radiator with customized exhausting strains is run through bleed factors to the enlargement tank, fixing the pretty widespread problem of Okay-series engines being exhausting 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 exhausting strains, 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. In the event you ignore the parents doubting DCT or Okay-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 choice 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 unintended scratches that include it, this was vital to me.”

Air-conditioning apart, the inside of the Silvia is a nice place to be. Take the wi-fi double-DIN head unit with Android Auto, or the 3D-printed cupholders rather than the handbook shifter. In his quest for drivability, Tom has retained a full inside. NVH is the enemy, in spite of everything.

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. Observe 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.

Quite amusingly, with the automobile working Tom may even function the horn with the wheel in his arms.

Tom PS13 SH-46

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 software and automobile cleansing storage.

Tom PS13 SH-47

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

Being a ’90s automobile, particulars such because the crystal clear headlights, indicators and ‘grille’ with no yellowing are appreciated. So too are the little mirrors, which all the time 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; forged and aluminium parts have been anodised in black; fittings are plated in yellow zinc. Alongside subframe reinforcements and a set of customized jacking factors for straightforward lifting, the ground has been stripped, stone chip coated and completed in black chassis enamel.

Relating to automobiles, stability is way too typically neglected as of late. House owners the world over try to construct the wildest and rowdiest automobiles they’ll, solely to face out from the gang. The bottom, the quickest, probably the most highly effective… the record 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 greatest. I believe this one could also be simply that, ‘one of the best’, don’t you?
