As you know I've been wanting to go with a turbo for a while, but funds once again, has been keeping me away from doing this. Now that the Greddy kit and Interceptor-X and all of these new mods are coming out to pull around 300-350rwhp with the Greddy, I'm deciding to go with the Greddy kit for now, but what do I need essentially in order to run the kit and then later down the line when I have the funds, am able to upgrade like a bigger turbine, injectors, etc etc. Here is what I was thinking what I need to get up and running.

Greddy Kit
BOV
Boost Gauge

These are the basics for running the kit at stock boost correct? Just this would get me running fine? Now later down the line if I wanted to push in the 300-350rwhp with the Greddy, I would have to do the following

Interceptor-X
Upgrade Turbine
Larger Injectors
Boost Controller

So the question I am asking, for a basic turbo kit, to get up and running, I don't need the boost controller or any of those advanced things yet right? I just need the kit, BOV, and atleast a Boost gauge to know what's happening right? Then later down the line, I can add and upgrade all of that.

Bump for some help?

I can tell you that nobody will answer this for you speaking from experience. It seam that if a question is asked more then once on this forum you do not get much help. I just called injected performance for answers they are in the major horsepower upgrades..

to just get the car running on boost, all you 'need' is the greddy kit.....

to get it running well I would say the greddy kit and BOV....you dont really need the boost gauge for running stock boost on the kit...but with how cheap you can find a basic one, it doesnt hurt to be able to keep an eye on it.

The big thing with getting more power out of the greddy kit will be the computer, the interceptroX as well as the new greddy computer will both be options for fairly inexpensive control of the engine, that will net you some big power gains as well as help you dial in the power band where you want it.

Once you optimise the engine for the effect you want with the new computer, if you still want more, you could go with a better turbo. More airflow at a similar boost level would get you some more top end power. Then you could upgrade the fuel pump, injectors, add a boost controler, and tune for higher boost (might need some higher octane fuel) and finaly

You could also pick up a few spare HP by upgrading parts of the exhaust and intake system. Im not sure how good the greddy kits inter-cooler is, there might be some room for improvement, especialy with a larger turbo.

The question I am asking is will it make a difference if I add things later down the line? For instance, if I just get the turbo and BOV now, and then later down the line, want to add gauges, will it be hard for someone to install the gauges? Same question about all the other parts, is there any drawback in adding parts later down the line with the turbo?

From what I've heard, with an upgraded turbine, interceptor-x, and greddy kit, I could push around close to 300rwhp. Right now the only performance mods I have is a RP high-flow cat and Greddy exhaust.

I basically want to get up and running with the Greddy kit with the cheapest amount of money (say around $4000 installed) and then as money comes in, and funds become avaliable and loans are payed off, I will be able to add gauges, interceptor-x, upgrade turbine, injectors, boost controller, etc etc.

adding parts down the road to your car with the greddy kit will be no differnt than adding parts down the road to a stock car.

If your looking for bare-bones, cheap, getting running, get a new/used greddy kit, install it yourself/shop and add the BOV. Then your set.

You can add gauges, boost controlers, computer managment, ect down the road with no problems.

Really the only things that might be difficult later on is finding a turbo that will fit the manifold and clear the frame, ect...it would also most likely need a new downpipe if you switch turbos.....if you were to go with a bigger/better intercooler you might have to get new pipes...things like that.

Do you think I'd be able to install the turbo myself? Let me clear this first up. I have NO type of experience on working on exgines at all, however, I will be going into college and as a freshman, we cannot have cars on campus, so my car will be garaged at home (only about 20min away) so do you think I would be able to install it over time since I most likely won't be driving it, I'd be able to install it myself or should I bring it to a shop and get it installed. My dad would help install with me, however, he is not too informative about the rotary as well. He has a 1974 Porsche that he works on, but older cars are a lot easier to work on. How difficult is this install?

KYLiquid

i havent put the greddy kit on an RX8 myself, but I have turbo'd other NA cars before, as well as doing upgrades to turbo cars...ect.

I have little formal training, mostly i taught myself, read books and shop manuals and watched/helped friends.

There is a lot of work to do, but none of it is really hard, I would think you could do this install with a good set of tools, some time and some good jack stands (maby 24" of clearence under the car) a friend that has some mechanical ability would also be welcome.

For this turbo install its really not about the rotary, the install is gonna be the same as any other car...its all bolt on componets.

Here is the rating system I would use 1-10 (easy/hard respectivly)

New Wheels - 1

New Intake or Catback (bolt on) - 2

New Suspension (coilover) - 5

Greddy Turbo - 8

Motor Swap - 10

--------------------------------------

If you take your time, read some of the how-to's and have a basic knowledge, or have someone that does have a basic knowledge it should be pretty easy...the hardest part is working in tight spaces....

what do you need to run a turbo? *****.

Even getting it installed by a professional has proven to be problematic for many members. Besides the fact that only a couple of people have achieved the advertised HP increase due to most losing boost because of leaks and such.

you won't get 300-350whp from Greddy
try 280-290whp instead with interceptor x

lurch519

first you need a turbo,

HardHitter

I believe that we'll be able to get 300-350wrhp from the Greddy. If they are already pushing around 290 with the Interceptor-X and all stock engine/injectors/etc I think once they upgrade a couple of things they'll be able to hold boost and get in the 300-320wrhp.

It'll take some time, and some trial and error, but with all the new things coming out right now for performance, I think it's only a matter of time before someone starts pushing their engine into those ranges.

the greddy kit can not flow enough air to make that horsepower figure. you need a bigger turbo. all the extra power you are getting from the interceptor x is from trimming the fuel back some and leaning out the air fuel to make more power
