Problems
I am having a few problems. It seams as if on of my run off tanks for coolant, the plastic one on the passenger side*left* has a hole or somthing so when I fill up my coolant, a few hours later I have a add coolant light. Also, I have been having a problem with the car will over heat after I make a hard run *higher speed* does this have to do with my stock radiator just sucks and cant cool it well, or maybe the thermostat is getting stuck? I rarely can get the car in reverse since the over heating. And in 3rd-4th I get a boost or fuel cutoff. When it hits I can restomp the gas and it will go again. Does anyone know what causes this? I checked my plugs and cleaned them and it still does it. Also, when I hit boost 1st-2nd i get a crazy vibrating, almost feels like the tires are breaking loose. but in other gears if I am just cruising and hit the gas I get a clunk. Anyone with any sort of imput please help.

You need a new AST it sounds like. And at the rate you're overheating, you may need a new engine soon too...
Check the 'Newbies' thread for info on the AST, or air separation tank, it's one of the first things you should replace when you get an FD.
As to the hesitation...i don't actually own an FD yet...so maybe someone else can help you with that

Its a brand new motor. It only has 3500 miles on it. I turn the car off the second I see it go over 9oclock. I know about the overheating problems. When I overheated once I did burn some coolant off in my exhaust when I restarted the car after filling up and what not. But I havnt seen anysince. Which one is the ast tank? I know there is the main coolant area, the overflow tank on the driver side *right side if looking at it from front* and that plastic tank that has the plastic top and is clear. taht clear one is the one with the hole in it.

Definately check the AST (air seperation tank). It is located to the left of the battery and behind the intercooler. It is black plastic with a cap that says to never open. I would recommend doing a search for "ast" to find out all of the symptoms and where they tend to break.

yeah, you are supposed to fill put the coolant in the thermo housing cap, not the overflow, if you put it in the over flow, it will... overflow. I did the same thing on mine and ended up taking apart the whole wheel wellt to see where it was leaking. I found that they design a hole on top of the overflow tank so you cant overfill to to much so thats0 how i know.

don't race, don't need to
Have you actually seen the hole?
My $0.02: You most likely have a hole or leak SOMEWHERE in your cooling system. If the system is not COMPLETELY PERFECTLY sealed, it drasically reduces the systems ability to function and cool properly. Now, the system consists of the radiator, of dubious quality, that can give a slow leak and eliminate the ability for the system to hold pressure; the AST mentioned above, the stock one being a total liability; the coolant caps, which shoud be as new as possible; the heater core, which I haven't run across as being leaky, and you would smell this in the car if it was; and fourteen coolant hoses, any of which can develop pinhole leaks that are very difficult to find. If you are losing coolant after some hard runs, what may be occuring is a leak somewhere eliminating the system's ability to pull coolant back into the engine as it cools (are your fans running like crazy? They should be if you are overheating as much as you say!). Check the entire coolant system, looking at iluvmyRX7.com for routing and locations.
I think the crazy vibrating in 1st and 2nd is wheel hop. STOP IT, you will destroy your rear end in short order.
Anyway, sure driving awful hard on a less than confident auto, no? Again, my $0.02, now worth half considering how long this post is and inflation and all...
