Hey guys,

I am needing some advise on boosting my 8. It is a 2005 MT. Here are the current mods that I have done to the car:

Rotary Performance Racing Midpipe
Racing beat Intake
Unorthodox Underdriver Pulley Kit
Greddy SP2 Catback Exhaust

I am throwing the idea around about adding a turbo kit. From what I have read, Greddy seems to be the way to go. I am needing some advise on what I should do. I know that there have been some updates done to the greddy kit. 1. Are there any other good kits out there for the 8? 2. Would I encounter any problems if the installation is done right? 3. What kind of gains would I see? Is there more that one Greddy Kit out there? Im just looking for some Pro's and Con's on the latest stuff. Any advice or tips would be greatly appreciated. Thanks guys!

1.yes

tips: search the major modification thread and don't let Mugatu see this thread

WTF?? Why the smart *** reply. Yes, i know there are other threads regarding the turbo kits. I am just looking for some advise. I know that there have been some changes made. And wanted clarification. THANKS FOR THE HELP!

1. yes there are other kits out, but none is concrete (correct me if i am wrong).. My preferance would be Mazsports kit

2. The upgraded kit has not been tested that thoroughly... I am sure the e-manage ultimate is superior to the blue for tuning but i am concerned at that plate that they have you install.

3. Gains would be quite a big amount... You would go from 170WHP to anywhere abouts 300WHP+

4. Almost all the greddy kits out there on sale now would be the upgraded ones

lastly, it is a very common thing for people in this forum to tell you to search. There is actually a wealth of info hidden

Thanks KJ238 for the help. I guess I will have to keep browsing the web to find the info I need. Know of any other RX-8 sites that have good info??

all you need is right here on this site - you just have to do proper searching instead of asking for adviCe. laziness is no excuse.

If you want honest advise. Don't get Greddy. Wait until the PTP Motosports is out. Will be a better, more complete kit. This is from somebody who has a Greddy turbo on his car. Even with the EManage Ultimate there are other limitations on this kit. It has taken me thousands of $ to basically "fix" this kit from Greddy. I would advise you to wait a bit and get a more complete kit.

MadDog

My advice to anyone right now would be to buy a used GReddy kit for less than $3k and buy the IntX. The IntX is the easiest, but not the only, way to fix all the problems the GReddy kit had from the start.

Don't wait for any other kit - we've been waiting for *YEARS* and no one else has anything viable on the market. Buy the GReddy kit, get it tuned for 10psi, and proceed to waste SC'd Cobras, tuned STi's and just about anything else that you might encounter on the street. But stay away from the 911 turbos. They'll still eat your lunch.

Nopstnz

I agree with fanman, wait for something else then give us the details on how it is.

MadDog

one thing is for damn sure: If you go with something new (unproven) you will *always* spend more time and money than if you go with something that hundreds now have experience with.

Fanman

Sorry, I disagree with this. I would almost never get a used turbo kit. You never know the abuse, or if he properly cared for, the previous owner put on the turbo. Also, the Interceptor X is not a cure for all the shortcomings of this kit. The hoses are cheap & flimsy, and get brittle fast. Not to mention the turbo size is about maxed out for the area that they put it in, and 10-12 psi is about the limit for the small turbo.

Having personal knowledge of the PTP unit, it is about ready for release. They did things the right way & tested parts with the kit first. And they are introducing a complete system vs. Greddy's haphazard introduction of their kit. The parts are decent, but not the best, and that leads to several limitations, that a good fuel management can't solve.

We'll disagree. My advice is wait for the PTP unit. With Greddy, you get a decent unit, but not great & you will have to spend thousands to make it work well.

PTP puts the turbo in front of the motor.
Lots of pipe, lots of heat, lots of stress.
I've done kits that way (and I know a lot of 7 owners that end up with their huge turbo up in front) and it sucks.

MadDog

and blows.

Fanman

Unfortunately space on the 8 is limited. If you look at the SFR kit, that is where they place the turbo as well. The placement of the turbo in the Greddy kit in the right wheel well limits the size of the unit. But you know that. On the 8, can't think of too many other places in the engine bay to put the turbo. Would be interested to see what Mazsport kit has/will do.

The right solution is where the GReddy kit has the turbo and use a much more modern scroll.
Something really expensive and blingy.
A nice, GT-series Garrett ball-bearing, water-cooled thing.
When I hit the lottery (or sell a couple of hundred units of my tuning video), that is the way I'll go.

Probably the only circumstance under which both are possible simultaneously.

BTW - are you going to teach me how to tune this Int-X I'm picking up tonight?

I'm putting together a comparison and tuning section for it as well.

MadDog

Wow! You're getting it tonight? Awesome! I'll be happy to share what I've learned with you. You've got my cell #. But wait until tomorrow to call. I'm trying to get a little of that 'simultaneous' action tonight

Don't break anything. But if you do, take video.

PTP perfected the kit on 1 test car. I'll bet you a beer Greddy's test car ran perfect also. The test is when you release the kit to hundreds of owners and see how it fairs.

As long as you are willing to invest some time fine tuning the kit, and spend some time reading up, you'll love it!

Fanman

That is actually incorrect I know for a fact they have 4 cars that they tested it on. There is a large distinction between testing something on a car for a few months & testing it on several cars for a few years. Greddy wanted to be the first to the market. And they were, but that was at the compromise of their fuel management. PTP, SFR, & Petit did it a different way were they put tens of thousands of miles on their test cars, tuning their kits, and instead of rushing something to the market they put time in to revise the product properly.

The Greddy is a decent kit, nothing more. Even when we tuned the daylights out of the blue EManage it still had several compromises. With the new Ultimate, & the update kit, maybe it will be the kit it should have been. Essentially they released a half assed kit, and made the early adopters figure it out the work arounds. To say otherwise is disingenious. Hence the people basically ditching the FMU, and doing a bunch of other stuff to this kit to get power, & drivability.

Early adopters always pay the price - and reap the rewards.
I think the car itself is a testament to that.

OOOhhh... Tell me more about this bling bling... I might just go that way


Mine is being sent out today.... Will probably arrive in a week or so.... Please drop some tips to me.... Will be appreciative of the help as always
