greddy turbo comparison
so i've been researching some turbo kits and i'v seen the 3k greddy turbo only has minimal HP increases as is but is it capable of being tuned to compete with such kits as mazsport and ptp's 300-350 hp?
i like the idea of spending 1/2 as less money to get the same power
sorry for the newbie question

no. the engine starts to suck up more air than the turbo delivers after 7k range.
you could get the greddy kit now, then later upgrade the turbo - that'll add another 1k to the pricetag.
Meanwhile, compare how the greddy stacks up with other kits:

for a daily driver, greddy is damn nice.

you can make 300 whp with the greddy kit, but it will still peak around 7k. the other kits from what I've seen seem to stop at 330 for some reason. Eventually we'll break past that once all the issues are worked out.
I wouldn't call the gains minimal...

i think maybe to many FandF Movies... thinks turbos are the answer.. thats how i use to think before i got informed, that once you slap turbo on it, you are unbeatable...so then he sees that the greadyy only adds 80 whp, and he thinks its small

Not that a 8 with GReddy turbo is the greatest thing out there, but you'd be suprised what that extra whp and tq do. You can keep up with and beat quite a lot of cars. Take a ride in a properly tuned one. You will love it.

stock greddy turbo. I heard the modifications of the turbo itself don't give much gains, so I haven't bothered..
Theres another thread on the forum about drop in replacements. I don't know offhand. Also I know mazsport has made at least one greddy kit upgrade that relocates the turbo... so that's another route to take.

It was sent back to the tubo shop it came from and the customer is asking for a refund, I believe I have an even better bolt-on replacement we will custom build for the customer.

inside my head i want to turbo my car, i love the idea of improvement over stock, and to have some individuality with my car. but the thought of spending $8,000 just seems absurd.
so hearing about the greddy's +300hp result seems like a miracle. how much more money, from the orriginal 2-3 cost of the kit. is needed to make it reach the 300-350hp range?

depends on your goals. depends on your budget.
a lot of the stuff that comes with the mazsport kit standard aren't included in the other kits. As you increase power, or want reliability mods, you eventually buy these parts piecemeal.
It all boils down to a snail, some pipes, and supporting mods to make sure your car doesn't blow up. There's enough information on this site for you to research for days. You should try to form your own conclusion instead of asking others to make one for you.

I used to have a civic that I put a Greddy turbo on. I went from neck and neck races with my friend to 3-4 car links past him with just 5psi. It made the car a hell of a lot more fun cause I could race a huge range of cars after that.
I plan to use the Greddy kit on my car soon if the AFSC never comes out. I dont want HUGE numbers I just want fun and to get the car to the 250hp it was suppose to have. Why, cause most any car motor can handle low boost fine, the clutch will be ok (if your not crazy) fuel system,cooling,traction,lsd all will be fine.
You can hit 300whp, but its not any good if you can't put it to the ground. That will cost you more$ You could have 300hp and I could have 250hp. If you don't hook up as well as I do you'll be chasing me.

The amount of fun you get from going stock up to 250 whp is similar to the change from 250 up to 280 because of the added torque.
For a while I was switching between high and low settings on the boost controller. But I've quit doing that because sometimes I would hit the throttle then had a brief second where I wondered what's wrong with my car because it was suddenly so slow.

The RX-8 puts 300 to the ground just fine...

If you buy the GReddy kit, just get a BOV, get it dyno-tuned by a non-idiot, run stock boost, and you'll likely never have a problem.

It's possible to get over 310 whp with the greddy, but it's not something you want to do. The turbo will generate too much heat.
You can do a reliable 270 to 290 with the greddy. Beyond that, and you really need to replace the turbo. The good news is that the upgraded turbo costs about $1,000, and you should be able to sell your old one for $400 or more (Especially if you plan on the upgrade while the greddy turbo is unused).

Jason, where have you found the GT2871R for $1K? The best I've seen it for is $1115 shipped. Is that price with the with the GT 5-bolt discharge housing, T25 inlet, internal wastegate and actuator, and .86 A/R on the turbine side as well (because that's what you need)
