stick to the bolt ons first if your doing your engine first. But if i could do my car over i would ahve started with the suspension first to control all the power later. when io say suspension i mean every thing like shocks, coilovers, strutbars, tie bars, sway bars, upgrade everything first. trust me if it doesnt seem like fun, it is once u can fell the differences between the stock. If u are then doing engine work start with intake exhaust header intake manifold , high flow cat throttle body. By that time u should have a lot of fun.
