hey im a newbie to the rotary tuning, so i was wondering what is your opipion on a turbo II. I want to use it to drift in so im going to push it hard, so i was wondering about reliabillty. I've heard stories about blowing seals and destroying rotarys, and also major oil leak problems. i heard that replacing the seals off the bat and regualar oil changes will keep it running like new. But i know nothing about rotarys so i wouldn't be able to do the work myself, has anyone heard of Fast and Clean its a RX-7 only place in NC, but i heard some negative things about it. i want a turbo II but i don't want to worry about blowing my rotary, any suggestions?

the everyone's deal with drifting?

They seem to think drifting is cool...seen to may rice movies.

If you don't want to worry about blowing it, don't modify it. Stock, they're pretty reliable, but if you start modifying the car without knowing what you're doing, you'll blow it.

Also, try SEARCHING.

well the whole idea behind this post was to get some info about what to do to the engine to make it more reliable after modifying it

Build it well. That means FULL engine mangement system like a haltech, larger injectors, etc..

Make sure your air/fuel ratios stay perfect, add proper blowoff & popoff valves, etc..

If you build it well (like rx-7.com's monster dragster), you can push a 350+ HP very easily.

Rotaries last as long as most other high performance engines

You can make some decent changes without worring too much about reliabilty. Many say that a downpipe improves reliability by helping the heat get out. (DP replaces front cat, right beside turbo)

Realize that any turbo motor's performance will benifit substantially from decreasing the back pressure. In this respect turboed engines are more dangerous when modding, because the turbo is pushing more air in. Turbocharged engines will not last as long as typical n/a engines. In this respect the TII is not unreliable. With the TII in particular, the key is to be certain that the engine is receiving enough fuel. As such, once you go beyond the fuel cut at 8.6psi you need to add more fuel.

You want to drift?
Get a 4.30 diff out of a GTUs.
Get a down pipe, a Turbo inlet duct, some sort of cone filter, and fab up a nice intercooler... or buy one if your loaded. Then all you need is a bigger fuel pump, and an FCD. Boost should hover around 10-11psi.... and you should have fairly decent EGTs if you have a nice IC and a walrbo fuel pump. You could take the expensive route(the right way) and have a 400hp motor, or you could do what I suggested and have around 250hp, which is a happy medium if drifting is what you plan on doing. The way I suggested is pretty reliable if your fuel system is 100%. I would maybe suggest getting some bigger secondaries, though it would probably cause a little hesitation in the low end. But if you are driting you shouldn't ever see below 3K rpm. I would just say go out and get a haltech, but not everyone has 2K dollars to spend on the haltech unit+dyno time.

I didn't realize that there were any drifting racing events in the US which are open to private individuals. Would you car to fill me in, as it sounds kinda fun?

... and I've heard stories about throwing rods and destroying valves, and also major oil leak problems in piston engines. I guess the best thing to do is live in a giant bubble and never buy any type of car in the first place.

Never heard of them. Try here for all your NC questions:

Racing requires time and money. The more racing you do, the more things break and wear out, the more time and money you spend fixing them. This goes for rotary engines, piston engines, jet engines, brakes, tires, transmissions, and maybe even the little statue of Jesus on the dashboard. If you can't afford to race, then don't do it, especially if you only have one car and no truck and trailer to pull it with. I realize that this may sound like a slam, but it's very important for you and others to understand, and just may be the best advice you will get in this thread.

... or longer.
