disa

Hey all...

I have recently bought an Rx-7 -99. However, I am quite new in general with dealing with cars, other then driving them, and this is my first own car which I intend to modify. I just wanted to check, please use layman terms, what you guys reckon is the best way to go about upgrading the engine. So far everything is stock, and mainly i want a drift settings, though also upgrading the performance and top speed as well. What should I have a look at first, and what parts are most important to upgrade, with regards to both performance and durability.

Since I live in Sweden, where the Rx-7 is a very unusual car, I will need to order most parts from overseas. Perhaps anyone can recommend good sites for upgrading products?

If anyone has any other pointer what to think about, please mention them as well.

Cheers.

congratulations on the new car disa!

The FAQ's at the top of the 3rd generation section will provide you with an invaluable amount of info regarding the upgrade path to take.

Generally you would want to first do your reliability mods which would be cooling and fueling your rotary.

Upgrade the intake, install a downpipe to eliminate that stupid pre-cat (will still pass emissions), and perhaps an upgraded rad and IC if your budget affords it. I'm not sure if the 99's are still using the same MAP system as the previous series vehicles, but if they are you want to watch how much you mod the car because the stock ECU will not be able to compensate and an aftermarket computer such as the ever popular Apexi PowerFC will be necessary.

Others can chime in with more specific advice, but make sure 2 read thru the FAQ's in the 3rd gen section of the website.

Cheers!

Your car does not come with a precat disa (this was something they only installed on US models so they could pass US cold start standards).

I don't know much about setting up for drifting, however I would check into starting with reliability mods; an upgraded AST, replace the radiator with an all aluminum one (Fluidyne or Kono). If you intend to modify the exhaust system than it would be highly recommended to install a PFC w/ Commander (Apex'i makes an after market Fuel Computer *the PFC* which replaces your stock ECU and will allow your car to safely run at higher boost levels. The US maps cut out at 13psi, I don't know if the '99 model addressed this or not, you may want to look into it.)

One thing to keep in mind, ALWAYS use the highest ron/octane pump fuel available.. if the fuel in the engine is not rich enough than you run a higher risk of detonating/pre-igniting/knock, which will effectively destroy your engine. Fast.

But yeah, I agree with DeAd-EyE. Check the FAQ, alot of the basic (and advanced) questions have already been asked and addressed on the forum. I myself spent about 4-5 hours a day for a whole month pouring over the FAQs and reading anything and everything that seemed pertinant before I bought mine. Read as much as you can before you go tinkering with the engine, there are pro's and con's to anything you can do. Remember, the guys that designed the car are some smart ****'s.. you really need to know your **** before tampering with what they did. These car's are MUCH more fickle to change than piston engines. I would say do any mods to your car one at a time, so you can note any changes based off THAT particular upgrade.

First things to get:

Aftermarket Boost guage
Radiator
AST
PFC w/Commander
Intercooler (there are three different types, a V-Mounted, Side mounted, and Front mounted, read into the differences to see which will work best for you)
Intake
Cat-back Exhaust

Just doing the standard reliability upgrades should put you up to, if not over, 300rwhp. Take your time and make sure you do it right, the first time, you will probably get much more enjoyment out of your car this way.

Grats on the new car, and best of luck!!
