With what some would consider the most grueling part of the swap Tech2 sought the assistance of nearby tuner Motorsports Dynamics. There Henry wired up a harness and tuned the JZ to an HKS V-Pro. Henry was able to get the engine turning without a snag, but that's not the end of this project-that'd be way too easy. While the engine was being wired and prepped, the car was stripped to bare metal and received a six-point chromoly rollcage along with all the obligatory stitch welding: Andrew wanted the chassis as stiff as possible. With the engine and chassis in check it was time to give the exterior some nipping and tucking. A Kazuya Bai-designed widebody by Origin Labs would help accommodate wider tires all around and improve the car's stance; the APR dry carbon GTC wing, front splitter and carbon mirrors just look fly. EMS'ed straight outta Tokyo, A'PEXi's N1 drift-spec coilovers drop the ride height and aren't too shabby for the track either. The 18-inch Enkei RP03's shod in Nitto NT01 rubber look that much bigger flush against the dropped hatch. But it's the we-cost-more-than-your-college-education Project 14-inch forged brakes that make us cry like little school girls. With all the exterior cues out of the way, Andrew settled on an ostentatious Lamborghini yellow. What the hell, the car has over 600 horsepower and was solely built for the track, it deserves the attention. Road racing or not, yeah, we'll call this one different.
Rb26dett Vs. 2jz-Gte
Which Is The Ultimate 240 Swap
At a glance the specs reveal that the JZ and RB are two brothers from another mother. They're both inline-six, both twin-turbo with similar compression ratios and output numbers. Before you call foul, the power numbers listed for the 2JZ are from the US-spec mill. We chose to list those numbers because many of Andrew's swap engines come from re-tuned domestic Supra models.
While both engines are capable of producing quadruple-digit horsepower, according to tuners, it's the JZ that requires less work for more hp; and when we mean hp, we're talking 1,000 hp, not your typical 350-500 hp. In comparison to the JZ, the RB's shorter stroke allows the Nissan block to rev up higher and quicker, or so says Top Secret's Smoky Nagata. And remember, if you want an RB26 you have to source an RB25 tranny, the 26's trans is AWD.
The fact of the matter is that either engine will smoke the tires and put a smile on your face. It's just up to you which you prefer. And once you do decide what engine to go with, there's a crapload of bolt-ons that will work.
