Overseas Bastard - Nissan Silvia S15

Stranger Hybrid Than The Spork?

Text By Ryan McKay, Photography by Henry Z. Dekuyper

Every once in a while, we see something that makes us scratch our heads and mutter to ourselves, "What the hell were they thinking when they decided to do that?" The ever-popular spoon/fork hybrid we know as the "spork" is a perfect example, but this bastard Nissan is up there on the list. But, like the inventors of the spork, the owner of this car had a method behind his madness.

When Chinen Yoshikuni decided to build a demo car to show off his skills and the caliber of work done at his shop, C&Y Sports, he knew he had the perfect opportunity to show Japanese tuners just what a crazy and bad-ass car he was capable of building, and in the process, mop up the competition at the track.

His weapon of choice was the S15 Nissan Silvia. A capable and widely supported car in both the JDM and USDM markets, it would have been a cakewalk to just grab a bunch of off-the-shelf parts and build a plenty-fast track car. But that wasn't the point. All that would prove is that he has deep pockets and that C&Y has the ability to bolt on a few parts. Any clown can do that. No, Yoshikuni had a dream.

To show just how good his shop is, Yoshikuni decided to do things the hardest possible way. And in this case, that meant ditching the stock SR20. But instead of just installing a Nissan RB26 mill and calling it a day, he went off the deep end and started the build by doing the unthinkable... dropping in a Toyota engine. What better way to show off your skills than by doing something that's never been done before?

Shoehorning the potent Toyota 3SGTE into the S15 wasn't really a matter of just "dropping" it in, though. While the engine was still out of the car, he cut the chassis up a little so he could mount the 3SGTE mill a little farther back in the S15's frame to promote better weight distribution. Making sure the car was well balanced was of major importance. The car was built to do it all, drag racing, road racing, drifting, time attacks and whatever else he can throw at it, so it's gotta be incredibly well balanced.

A lot of time, fabrication, work and money was needed to get the car where it is now (over 6 months and $60,000), but the engine swap was just the beginning. Before the engine was swapped in, it received some serious massaging.

The 3SGTE was built from the ground-up to make some serious power. To hang with the fastest cars over on Yoshikuni's side of the Pacific, it needed a little bump in displacement, from 2 liters to 2.2 liters. This was accomplished using a JUN Auto crankshaft, a set of HKS connecting rods and oversized JUN Auto pistons.

While those mods alone would make any 3SGTE owner salivate, they're only the tip of the iceberg for the power mods. Everything you'd expect to see on a race car is present, including HKS intake and exhaust camshafts, HKS piston rings, and HKS valve springs. But not everything under the hood was off-the-shelf.

Everything on this car has been gone over and much of it is decked-out in custom parts, and the engine bay is no exception. Pop the hood and your eyes will feast on a buffet of custom one-off pieces, all fabbed up just for this car by its owner, including the manifolds.

The Toyota 3SGTE has a notoriously inefficient factory intake manifold and C&Y fixed that problem in short order, fabbing up the gorgeous sheet metal intake you see on the pages before you. On the exhaust side, they welded up a custom exhaust manifold to bolt the massive HKS T04Z turbocharger to. The downpipe and exhaust are, obviously, custom pieces as well.

A Blitz Racing wastegate works in conjunction with a Blitz SBC i-color boost controller to keep the boost level rock steady. For whatever reason, the guys at C&Y decided to forgo a blow-off valve altogether. Other custom engine bits include solid engine mounts, an Infiniti Q45 throttle body and a 4-inch downpipe, just to name a few. But C&Y Sports certainly didn't fabricate one of the hottest parts on this ride.
