I recently bought my rx8 and I am new to rotary power and tuning and I was wondering if anyone could give me advice on the pros and cons of both, like long term engine wear, reliability, quickness, cost etc.

 

TURBO!!!!!!!!!!!!!! that is all

 

lots of reading ahead of you, I forsee.
there are lots of useful threads here that can be found by using our search function towards the top right.

Use the advanced search and start by searching thread titles only.

You'll find that this board is quite split on the subject with Pros / Cons for both forms of FI. It really comes down to what YOU want out of your car, what you're willing to spend, and what you fits your goals.
Good luck, have fun with the research, and let us know which one you decide on.

 

If you have $15,000.00 or more, go supercharge.

If you have $15,000.00 or less, go turbo.

Do a search, lots of talk about both.

 

I really don't get supercharging anything under a v8, i just think its stupid

 

You must have never ridin in or driven a supercharged 8 then. It's pretty nice.

 

must have never ridin a turbo 8 either...i'd rather not pay twice as much for the same results, less reliability

 

turbo usually the way to go but i dont have either so i cant recommend

 

Been in a few turbo'd 8's. Not my thing...and you talk of reliability, what are you smoking? It's all about tuning.

 

Welcome to the forum. There is lots of great information here about the car and forced induction, check out the Major Horsepower Upgrades section in particular and read through the stickies. There is no "right" answer about supercharger or turbocharger, there are fans of both.

In general turbochargers will result in more torque, while superchargers keep a power curve similar to the stock power curve. They both will cost a similar amount to set up reliably, and there are various kits availabe. Kits which work with a stock ECU reflash will be more reliable, so do some research on the various kits.

If you are interested in the supercharger route, check out the Pettit kit, I've seen it and its very nicely put together. I personally prefer turbochargers, but its taken no small amount of effort for me to piece together my setup. In general I've found that setting up a turbo kit to work with the stock ECU reflash is harder, because most of the available turbo kits do not have a MAF setup that works properly with the OEM computer. SFR is apparently looking to update their kit to support the AccessPORT (arguably the best ECU option available) and Esmeril makes a pretty nice kit despite lack of support for the AccessPORT.

 

Power = Turbo
Ease = Supercharger.
Both are extra maintenance
Both are reliable when maintained.

If cost is even an issue, don't bother, save money, try again later.

 

wow,

this thread sucks and blows..

beers

 

she's gone from SUCK to BLOW!

 

wow I feel like I keep reading about the same "supercharger or turbo" threads.....search and decide what you want....basically come down to Tuning for reliablilty....bad tune is blown engine...good tune w/good maintenance then can have ALMOST NA reliability...but anything FI will shorten the life of the engine!

 

These threads get started every couple of days at least... we should probably have a sticky in the Major Horsepower Upgrades forum entitled, "Supercharger or Turbocharger?" which has the pertinent links in it and a summary. Maybe I'll write the post this weekend... depends on how busy I get with family stuff.

 

"I knew it! I'm surrounded by a$$holes!"

 

Wouldn't even bother, since the people that make these "Turbo vs Super" threads don't search and wouldn't be able to find it anyway. The info is already here in the stickies for the most part, yet people still make threads. Even if they could find the information, they would still make a thread because they need someone to tell them what to do since they are incapable of making decisions for themselves.

Better to have a few cold beers and enjoy your weekend with the family.

 

a big bag of suck filled with blow

 

If you have 15k, you better be putting a ported N/A 3 rotor in there. 300whp ALL DAY LONG!!!!

 

Not quit sure where in your searching youve pulled these numbers from but appears you need to go back and double check those numbers... Highly inaccurate...

 

Yeah, not sure where those numbers came from either... they are totally random as far as I can tell heh. In fact, if anything a good turbo setup will cost slightly more than a comparable supercharger setup due to the need for a boost controller, blow off valve, etc.

 

glad SOMEONE got the joke!



As for the $15k figures, that sounds awfully high.
REALISTICALLY, if you're going to turbo or SC and your'e doing it RIGHT (ie; no shitty greddy turbos or incomplete pettit kits), proper tuning, water meth, gauges, Boost controller, etc etc, be prepared to spend $10k.




disclaimer: not knocking the pettit kit, just we all know it could use a little extra stuff to really show off its potential.

 

It also depends on how much of the installation you are doing yourself Jedi, how much a tune will cost you (ie dyno tuning), and how much you spend on supporting modifications like ignition upgrade, midpipe, intake etc. I would have a hard time separating mods I got to go FI from the cost of going FI.

 

blackenedwings: very good point.
That is sort of what I was implying when I said "do it right".

I just hate seeing people half *** something like an FI upgrade.

 

Yeah, unfortunately most people that half *** FI with this car don't do the research, just throw a used GReddy kit on the car, and promptly pop their engine. Then its constant complaining about how crappy the Renesis is.
