Completed drift build overcame succession of obstacles


Unique machine born from grueling work  


The owner of this car is a dyed-in-the-wool drifter. They originally used a Watanabe Service “Drift Center Diff” to convert this GRB Impreza to an FR layout for drifting fun. However, two blown engines, a blown transmission and countless broken driveshafts later, they found themselves wondering what would break next every time they drove the car.



Feeling greatly unsatisfied with this never-ending cycle of misfortune, the owner made the big decision to swap the engine. The candidate was a 1JZ-GTE, with its supreme reliability and sweet exhaust note. They immediately got hold of a JZX100 Mark II as a donor car, and set about using their expertise as a professional mechanic to carry out a do-it-yourself conversion.



Getting the 1JZ to fit forced a number of other modifications. These included cutting away part of the front subframe, and moving the steering gearbox around 30mm south of its original position.



The blacked-out turbo is a wastegate-equipped GT3037. A JZX-100 “Power FC” and the stock GRB ECU handle engine management.



As drift racing places heavy demands on the engine for prolonged periods of time, the cooling system gets a thorough work over too. In addition to the one-off front-mount intercooler, further upgrades include an HPI oil cooler and a Koyo/Flex radiator with heat dissipating paint.



The suspension is a custom setup, consisting of Blitz Damper ZZ-Rs with 326 Power’s “Majibane” springs (F: 32kg/mm, R: 20kg/mm). The all important steering angle required for drift racing is raised to the max by a one-off short knuckle. There is a definite sense that the owner, who enjoys both drifting for fun and participating in occasional car shows, is pursuing the twin goals of “How low can it go?” and “How well can it perform?”



Modifications to the transmission bell housing make the transplant of a Z33 six speed gearbox possible. An adapter joins the (stock) Z33 carbon propeller shaft to a Toyota eight inch differential (from the BRZ). Apparently the owner left the work on the transmission case to a specialist. In addition, extensive work on the suspension members and control arms head off any problems that might be caused by the low ride height.



The bolt-on wide fenders come from Russian outfit “Fenderist”. Into the arches go 18 inch Volk Racing TE37SLs in massive 12J -33 offest size.



The cockpit design takes both performance and appearance into account. The wild-looking e-brake extension makes this instantly recognizable as a drift car. The cluster housing the row of four meters is a custom job, and there is a Momo Drifting 330mm steering wheel.



A roll cage with side bars aims to increase rigidity. The rear cross bars are specially made pieces, which can be fitted even with the rear seats in place. The front seats are a combination of a (Bride) Vios for the driver and a Gias for the navigator.



The finish on this car is competition grade. And yet at the same time it is capable of deep-angle high-speed drifting. It wouldn’t be saying too much to call this a flawless example of hardcore tuning. Incidentally, during the creation of this machine, the owner started their own business. Under the name “LittleBrave”, they are putting their all into helping clients build up their own custom machines.
