Helping the RB make these massive numbers is a Garrett GT4202 turbo. This snail is so large that it's not even shy about it-it literally sticks out through the hood. "The GT4202 has such a large A/R housing that I went in knowing there would be a bit of lag. That's why I added the nitrous. It's pretty ridiculous on the road," Karl exclaims. "Without drag radials on, it's almost pointless to hit boost. Even with them on, the car still screams all the way through 3rd gear."
To ensure that all the menacing power is transformed to the tarmac, Karl opted for the most traction and the widest wheels he could get his hands on. The 18x10/18x12 Weds wheels not only provide enough lip to make any offset fanatic drool, it also houses 335/30-18 BFGoodrich tires in the rear. Yes 335, no stretch needed here. All rubber so that Karl stays firmly pushed against his seat and the FD stays on the road.
Obviously, you can't just go out and throw on some 12-inch wide wheels on a stock-body RX-7. Karl lives in Wisconsin and isn't exactly a big fan of the lowrider poke so he widened the rear quarter panels 7-inches to house the Weds wheels. The front fenders were widened by 5-inches and Karl even went as far as to modify his authentic FEED front bumper to flow with the fatter body. The entire chassis was then re-sprayed in a Lamborghini Grigio Metallic hue. This RX-7 is no Lambo, but it could definitely feast on a couple of them.
The interior is straight to business; Kirkey Pro Drag seats, S&W 10-point rollcage, 15-gallon aluminum fuel cell, and two 15-pound nitrous bottles ready to take Karl to light speed. Defi and Stewart Warner gauges adorn the entire dash to notify Lindgren of all essential engine operations.
There isn't really much we can say about this hybrid RX-7 that can't simply be described by one word; "awesome". It's a beast. Karl Lindgren may not be a mad scientist seeking genetic perfection like we've seen in the movies, but his RB-powered FD is definitely a freak of nature and it has the balane of power in the palm of its hands.
