If a stock Corolla is fun, a heavily tuned Hachi is downright sinful, particularly if the motor runs four extra valves like the JDM 20v Silver Top engine Joshua swapped under the hood. "A ton of fab work went into getting the 20v to work with the AE86 chassis, as no one offers a bolt-in swap kit," says Joshua. A CNC operator by trade, Joshua flexed his skills reworking the cooling system, bending and welding new aluminum lines, and fabricating custom block-off plates and flanges. To get the new motor to fit and fire, the crank pulley and the trigger wheel on the 20v had to be machined and welded. For spark, Joshua plucked a MSD coil unit designed for a SRT-4 and used modified MSD plug wires originally intended for an Integra.
Optimizing the efficiency of the 20v, Joshua converted the intake to pedal responsive individual throttle bodies using a Megasquirt standalone ECU with a Ford EDIS crank trigger ignition system. Since there are no bolt-on exhaust kits for an AE86 running a Silver Top motor, a rear section of a HKS muffler was paired to a Flanagan's custom piping fitted to a Danstoy stainless tubular header and Innovative LC1 wideband O2 sensor. A Koyorad aluminum radiator and dual FAL 10-inch fans keep the high-compression motor breezy, while a GReddy oil filter relocation kit and custom stainless steel lines add some sparkle in the engine bay.
Going with the clean JDM look, Joshua picked up a set of Kouki front and rear bumpers and a Zenki front lip for an added aggressive look. The rear wing is OEM, however the Redline taillights, corner markers, halogen SS yellow motorized foglights and emblems are all straight JDM. As seasoned as Joshua is at building cars, he knows it takes artistry combined with experience to paint a car. So despite his pride on building the car entirely himself, he relinquished his Corolla to Caesar and Val over at Autocrafters and had them shave the antenna and spray the car a new coat of Toyota Super White.
Continuing with the clean motif, Joshua tracked down as many non-cracked, unworn interior panels, including rare factory seats without their orange spongy guts exposed. Joshua replaced the a/c controls with a carbon fiber panel lined with Defi gauges, then sourced a Levin steering wheel modified to work with a quick release hub. Other interior trinkets include the ubiquitous Broadway mirror, Weapon*R floor mats, and Razo pedals and shift knob. For tunes, Tejano or otherwise, a JVC head unit pumps music out of a combo of MB Quart and Cadence speakers.
