AE86 N2 Components by TRD
Contribution by Richard White
Here's what you'll need to make your racing application engine with the 4A-GE by using TRD Technocraft Japan components. Some of the parts are now available at Toysport America in Gardena, California. Call (323)755-1177 for more information on these racing only components. These are neither street legal anywhere nor very useable for street use, so don't even ask them if they are... Fully equipped they make really nice racing engines, that were used for N2 class racing in Japan back in the late 80's.
Thanks Richard for the tireless efforts to make Club 4AG a better place!

My purpose is to inform others that a 200HP naturally aspirated engine will take
lots of special pieces. I have copied and summarized all of this information
from the "TRD Corolla, Levin, Sprinter, Trueno, Special Edition Bible", dated
1996. Though I have tried to double check my entries, you should inform the
readers there could be mistakes and you (me too) are not responsible for damages
resulting from these errors.
