Thanks, the floor is still wet in those pics above the sealer isn't going to change the way it looks much if at all. Sticking with basic concrete no epoxy job. The floor would need ground first anyway so I may consider it in the future.
BTW I was looking at your slippery slope thread, save your money just fix your stock motor, put valve springs on it if you haven't already. I would upgrade the entire fuel system and add a 67mm turbo with the proper TQ converter that and a good set of tires are all you really need to have a 10s car. If you plan to go faster then start looking at the motor but IMO I would upgrade the fuel mgt to an aftermarket setup before doing that and you will seriously need to consider safety equipment at that point. The safety equipment is what makes it a "race" car and not a street car. There is nothing daily driver about spools, roll cages window nets and 5 pt harnesses!
