I have a tta just about stock cond only a few bolt ons. Now as you may or may not know, I bought this car to drive while my gn is down for a complete engine rebuild, the engine is now just about done and I'm wishing it would have taken longer. I am having so much fun with the tta. Just more fun to drive. I know the tta is capable of some good track times with bolt ons but I wanted a 10 sec car with no worries . (or as close as possible) I have a fully built 87 gn engine with a std. tta crank, steel caps polished rods forged pistons ported heads big valves nice cam ported lower helmco upper te-63 57's all the goods for the gn. NOW . since all this started I also aquired a 57 bel air conv. I can only keep one of the turbo cars when this is all said and done. I'm not parting with the 57. I guess my question is what would you do. ?? Put the gn built eng in the ta and put the stock ta eng in the buick and sell it , OR keep the tta stock and sell a 10 sec gn ,OR sell the tta and have a bad ass brick? the Gn is in super shape excellent paint/int, 12 brake upgrade, bigger sway bars, all poly bushings, ssm lowers, boxed uppers, kybs, gnx wheels so it's not a stocker 90k ??? ahh why can't i just keep both ( the wife is not going to allow it ) I also have a 4x4 truck atv and some other toys so she is not budging
