Welcome to The Car Of the Month
Here is my 84GS that has been under construction for the last 8 years. I originally paid 400 bucks for the black on burgundy wreck which had been sitting for 5 years with a blown engine. Over the years, thanks to this site) its gone through a lot of changes, from a stock 12A, to a 13B 4 port with a Yaw Nikki.The choice to go TII was made because of lack of further power without porting, and ease of smogging.The final product is in the range of 300hp and is very streetable and completely smog legal. Despite being a handful sometimes, this is daily driven, very well balanced, complete machine. It was never built for show or drag race only. Current chassis mileage is 225,000 and rising fast!!!!

Any future plans will be minor, this project is done, finally. Ill be installing some spacers to push the wheels out a bit, enjoying a little autocross cone chucking fun once the paint has a few dings in it), and keeping up on the maintenance.
One big mod looms in the possible future though,…..if I can do it legally, a 20B-REW twin turbo conversion at about the same HP levels. Nice and low stress for a 20B,plus an awesome exhaust note and no turbo lag!
Special thanks to Mike and the gang for years of info and support while building this project,Gabe and John at Gabe\’s Custom Autobody,the guys at Mariah Motorsports,and all my buds for their help!
