In order to realize the 850 horsepower gain over the stock 3RZ, TRD had to graft on a set of Supra taillights. Ha! Just kidding. Thank you folks, I'll be here all night. Don't forget to tip your waitress. (That wasn't funny.-JW; Jonny, you're an idiot.-JN) In order to handle more than 2 bar of boost, a set of custom JE pistons and rings have been dished out to create a boost-friendly 9.1:1 compression ratio. TRD's custom titanium connecting rods hang from-amazingly enough-the stock 3RZ crankshaft. On the top end TRD performed the headwork and added some of its custom valves, springs, retainers, and camshafts with LC Engineering cam gears. The voluminous intake manifold is also a TRD custom job and on the other side of the air/fuel equation are two giant Weldon pumps and a TRD fuel rail feeding no less than eight Bosch 1600cc injectors. None of those cute faucet metaphors will work here. This is fire hose territory.
The Turbo
The engine's reduced compression and gluttonous ingestion of air and fuel are all needed to satiate the turbo. The snail is a Turbonetics Y2K unit. I feel very inferior looking at it, much like when I stand next to Ricky at the urinal. But Rado says the Y2K is an off-the-shelf turbo with a compressor wheel diameter of more than 82 mm. With the right package it is capable of making over 1,300 hp. Christian also tells us that TRD is working on some sort of new black magic technology that will keep the cylinder head nailed down in order to allow for more boost to take advantage of the Y2K's high horsepower capabilities.
Mo' Control With World And MoTec
World Racing is actually a subsidiary of World Electronics. You probably have no idea what World Electronics does, because most of it is super hush-hush government contract work. What this does mean is that World builds its stuff to the highest of tolerances. As the head honcho at World Racing, Christian is passing on all of this techno wizardry to the tuning community. He gave us the breakdown on World Racing's first new product.
"Of course our car is the first vehicle to use our World TBC-1 (Total Boost Control Version 1), which we feel is the first real high end boost controller. This unit has been one of the main focuses of World Racing and has been in development for almost two years. But the controller, which should be for sale by the time this issue hits the stands, has worked flawlessly since we started testing. This unit allows for extremely accurate proportional control of boost up to 100 psi for race cars or street cars-it doesn't matter. (So can I get one?-RC) We are able to control boost over gear, time, or rpm with no complicated calculation necessary. All you do is allow the controller to measure your car's actual gear ratios along with your car's actual tire size so you have accurate control for when you want to go fast on the street or strip. The TBC-1 also features built-in drag modes, ignition retard based on boost, a turbo timer, touch screen, and actual aircraft quality sensors and valves. This unit gives you accurate control all the time-that's the key-without the level of user complexity you'll find in competitors' products. (Right. But can I get one?-RC) But on the Celica I just use it to accurately control boost while I'm going down the track and it seems to be working great."
For engine management Christian relies on a MoTeC M880 system. "Tons of control and all the flexibility in the world coupled with excellent quality proved to be too valuable for us to pass up," said Christian about the M880. "George Ioannou from Bullish Motor Racing (who is also one of the Solara drivers) did the pristine install job on our car using mil-spec connectors and all the finest components to get the job done right."
