88 rx7 2nd gen N/A 77k mi radiator, electric fans, exaust, ect
 

This car is almost show quality and i do not want to mess it up but i do want to improve the performance if anyone could please recommend the correct high performance aftermarket
1. Aluminum radiator
2. Electric fan
3. Exaust, should I remove the catalytic converter?
4. Correct spark plugs and location leading following ect NGK?
5. Should I add a turbo? Is it worth the time and effort? How much HP will it add? What brand?
6. Anything else I should know?

I know these things have probably been asked a thousand times
Please be patient, I'm not an idiot. I'm worth the time. Please help.
Maybe some links for the products?

No one is going to call you an idiot in the new member section. However, as you alluded to, every single one of these questions have been beaten to death 100000 times and it's apparent you did not even try to search...we love to help, but you have to make an effort. Did you read the FAQ, which should have been a requirement when you joined? I will give you general answers so that you may research further.

1. Koyo N-Flow is arguable the most common "best" choice.
2. No aftermarket fan, that's for sure. Retrofit OEM options such as Villager, MKVII, etc.
3. Racing Beat is again, the most common "best choice". There's no reason to remove the cat on your n/a; your car already doesn't make any real power and won't make any more removing the cat.
4. I'm not sure what you're asking here...leading = lower, trailing = top (in regards to position on the motor). Mazdatrix will list what spark plugs are recommended for your year/model.
5. No. Again, read the FAQ. Sell the car and buy a TII. Also, don't butcher up and halfass a TII swap (which is inherently your next question).
6. Yes. Learn to use the search function on the forum. These cars have been around for 30 years, any question you have has already been asked many, many times.

Good luck, and welcome.

Thanks!

I've all read on here of alot of people using the radiator fan for early 90-95 I believe Ford Taurus. is another option for junk yard find.

That's good information, I'll check it out.
My add coolant warning buzzer kept going off so I searched
The awesomeness of the forum, and found that
Air was trapped in the coolant system

Followed the instructions for properly removing the air and it worked!

The car runs better now
