A crazy ITB setup used for drifting
This 15-series Crown has a large displacement 1UZ-FE swap
“I think the image has gone away in recent years, but don’t you feel like there are a lot of bad-boy drift sedans from the western Kanagawa area?” laughs the 27-year old owner of this Crown. “I’m a local there, but actually my car has nothing to do with that trend,” he continues. “There’s a high taste level that went into this Crown, combining various elements that I like into one car.”
The appearance is a straightforward and lowdown approach referred to as “jun-beta” style in Japanese. This means the car looks stock or relatively so, except that it has been slammed. This is a 15-series Crown, which became a popular base for VIP customization. This gives it that bit of “bad-boy” edge that the owner was talking about, even though the overall appearance here remains low-down but restrained. However, there is something lurking in the engine bay that will shock you.
The car is a base grade model which came equipped with a NA 1JZ-GE. That however is gone, in favor of a 4.0L V8 1UZ-FE out of a Celsior.
“Originally I was drifting a Chaser with a T67 turbo but crashed it. Then I found this Crown and started thinking about V8 with manual transmission which sounded like a lot of fun. So I started down the route to make this car in that image,” says the owner.
What’s more, this is not just any swap. Its a sports injection using OBX’s multiple throttle bodies. All the parts choices, engine swap work and ECU setting were impressively done by the owner himself.
According to the owner who has driven many various drift cars, “The low speed torque is really amazing. Even at 2000rpm the rear will kick out. Its definitely faster than a boosted RB25.”
Engine management is performed by LINK’s G4+Storm. All genuine factory gauges are set to work and even a cool mod that sweeps the speedometer needle with key-on was incorporated.
The suspension is based on a 326 Power Chakuriki Damper system (F20kg/mm, R12kg/mm). In addition, Ito Auto’s V1 knuckle at the front greatly increases the steering angle, while shortened upper arms increase the negative camber angle.
Wheels are RS Watanabe R Type in 16-inch sizing. Widths are 9.5J -19 at both front and rear. The brakes are genuine factory Tourer V ones that were transplanted from the owners previous JZX100. Tire choices are Advan Neova (205/45R16) at the front and Kenda KR20 (205/45R16) at the rear.
The front fenders were rolled and reinforced on the insides. The owner tells us, “If you want to get fitment like this on a 15-series Crown, you definitely have to roll the fender.”
The rear brakes are twin calipers with a hydraulic e-brake. The added calipers are from R32 Skyline Type M with mounting brackets made by Fat Five Racing. The rear fenders were also modified to accomodate the chosen wheel and tire setup.
The interior has a simple finish, although carpeting has been removed. The steering wheel is a Nardi Classic. The lid of the center console was modified because it interfered with the driver’s ability to shift freely.
The transmission docked to the 1UZ is a Chaser 5-speed R154 using a commercially available bell housing plate. The hydraulic e-brake is made by Skid Racing.
When converting from automatic to manual, it is common to just add a clutch pedal, but the owner chose to replace all the pedals. By using OBP organ pedals, higher operability for drifting was realized.
Full bucket seats by New Zealand’s Racetech are used for both driver and passenger.
A booster seat for the owner’s kid is affixed on the passenger side. “There aren’t many options for kids that fit full bucket seats, but this one works well” says the owner.
The owner tells us that the concept behind this car is “Southwestern Kanagawa Style”. When asked about future modifications, an unexpected answer came: “I want to swap to a 3S turbo and get power more easily.” Looks like we’ll need to cover this car again in the not-to-distant future.
