Yes HKS had a "twin charger" kit for the 4A-GE engine they also had a twin turbo for 5/6M-GEs. The 1G engine came in many forms -FE, -GE, -GZE, -GTE, and a twin turbo 1G-GE(1G-GTE). Toyota also had a few twin plug heads, and has used twin entry turbo systems several cars
Twin Entry= one trubo but with the dual inlets, or to put another way one large divided inlet.
I also beleive Nissan had twin charger system on some of thier smaller front drive cars.
