Hmm...I've looked all through these threads, and I see a lot of talk about how-to's etc, but not a single post (that I could find) saying anything like "WOW...my car is SOOOO much better now after installing the turbo!!"

Think I'll just use a lower gear and higher RPM if I want more power.

 

you've obviously never been a passenger or driven a turboed 8

 

turbo'd 8 > NA rx8....... hands down once you boost you'll neva wanna go back!!!!

 

no, i haven't. that's why I'm curious about how much different the car feels.

 

keep in mind there are various degrees of power from the turbo too.

for example, stock greddy at 6 psi is nice, but it's quite a bit nicer at 9-11 psi.

consider the difference between stock @ 180 whp, 120 tq vs turbo @ 290 whp, 230 tq. If you can't imagine that being worthwhile...

 

Take a drive in one before you make opinions. I promise you, you'll leave with a different feeling. The 8 with almost 300whp is awesome and is very different then stock.

The only problem is boost is addictive and you always want more!

 

I drove a 2005 bmw m3 back to back with my car, and the power is about the same. he just has a bit more torque at 2-3k rpm than I do because of the spool time.

 

sorry to hijack the thread but i am also wondering that some people in this forum are really not happy with the Greddy turbo, but my friend has had the greddy turbo since 26000 miles, adn now he has 68000 miles, adn he has no problem with that, and he is really happy with that.

 

I dont think very many people on the forum have the greddy stock PSI. From what I always read people are tring to get 9+psi and hit the 300hp mark. Then the motor breaks and "The Greddy kit sucks". "It doesnt flow enough". Everyone seems to forget its built for it's stock setting. If they could get more out of it w/o any problems I'm sure they would of. Most motors can take 5-6psi, once you go past that your on your own.

This is why it taking so long for the SC to come out. I'm sure they wont be out long before people are tring to tune them, then something will break. Remebering the bad is very easy, the good stuff fades pretty easy.

 

sounds like an urban legend.

it's not hard to make 280-300 whp with the greddy. you just need it properly tuned. If it's not properly tuned, even at 6 psi it'll be easy to blow the engine.

Any higher than 300 and you're going to want larger injectors and maybe fuel pump upgrade...

 

Keep in mind, adding a FI system to a NA car makes the car a bit of a 'project'. I've boosted cars which were MUCH more fun, but as I spent more time worried about boost, AF, EGT, etc, I lost a bit of driving enjoyment. I'd never hesitate to take my car to the track - but w/ FI? I'd have reservations.

 

I never said it was hard to get more power from the kit.(Yes, I know how a turbo works, more air needs more fuel...) It's just the way FI works. People always want more out of it, they arent happy with what they get out of the box. (not for long atleast) Why do these people buy a Greddy kit???

 

Yeah I could go spin the tires off the car and only have to worrie about the tranny right now

 

$3200 for a kit that gives you 110 hp and 100 tq isn't bad. At 4,000 rpm, it also gives you the most torque out of any FI available for the RX-8

 

I took my turbo off because I was not happy with the driveability of the car.Issues such as backfire in the exhaust,inconsistent idle quality,inconsistent performance depending on ambient weather.It made my car unsuitable for long distance touring.I had the e-manage blue and the car made 240 whp with factory cat and exhaust.
I was not prepared to spend any more time or money trying to make it drive like I wanted.
I much preferred the driveability of my slightly modified 1988 TII which made about the same whp.

 

its better to do a NA application instead of turbocharging more reliable & similar power gains

 

People may tinker, but with a turbo you can just get a boost controller and go crazy - or stupid - depending on your experience level.

Get that SC, and your capability to up the boost is doing calcs to figure out a new pulley diameter and then sending the specs to a shop to have it made. For the layman, this just isn't as easy to screw around with, imo.

 

Where do you get that?

 

you'll always be a torqueless wonder without FI on a 2 rotor engine.

 

Lotsa BS in this thread, so I won't linger.
However, when done correctly (which it almost never is), FI on the '8 is a beautiful thing.
It is possible to have better-than-OE drivability and 2x power. It just isn't likely to come from half-assed effort, which is the unfortunate norm for the typical FI kit purchaser, regardless of their sincere wishes to the contrary.

 

i would have to agree with mm on this... when done correctly the 8 + boost is great and very enjoyable to drive... its like they say, you get what you pay for

 

can someone please explain what the measureable terms of "done correctly" are?

 

upgrading the necessary parts to get the full power. Not just slapping on a turbo and hoping for 23805738476 whp. theres components that go with FI to help it out and make it run more efficiently; such as ignition and proper tuning etc etc. its more than just out of the box plug and play type of deal.

before reading these forums in january i thought turbos could just be slapped on and that was it, but you learn alot here. its quite the experience.

 

And tuning to a level of precision that equals or rivals the OEM.

 

Amen to that brother
