Default 200whp from Greddy kit? what would i need?

I'm getting a Greddy kit soon as payment for doing some website work. I like the fact that it's CARB legal. But.. i don't like the fact that it's only 150hp. I would like to make 200hp to the wheels.

But.. i'm a noob, and this is all just me asking stupid questions and learning from you guys. So.. tell me if this is what i need to make 200hp.

1. Greddy kit
2. Intercooler + piping
3. 1.8 injectors
4. AEM FIC + harness. I plan on using the AEM instead of megasquirt cuz this will be just a daily driver with no track plans. I think in my situation, a MS would be overkill.

What else would i need? and how much psi should i be pushing to get 200hp?

This could easily be found using a simple search.
Bigger injectors, better engine management, and turning up the boost.

Its not worth it with a greddy kit. Just use it at its usual power level and then get a better kit later.

With a '90-'93 car, you're both lucky and cursed.

On the one hand, you've probably already joined the Test Only Station club. On the other, you can get away with an awful lot.

When I lived in San Diego, I ran a Megasquirt ECU, big injectors, water injection, an intercooler, and other such illegal things. Fortunately, the techs just didn't seem to give a **** so long as the magic EO sticker was there.

Honestly, the Greddy kit isn't all that bad. I mean, the air filter is ****, and so is the intake piping, and the oil lines, and the FPR... In fact, pretty much everything except for the turbo itself is crap. But it's capable of over 200 WHP...

... so long as you throw out everything but the manifold and the turbo.

... and the sticker.

If you replace everything you can't legally keep the sticker. But most likely no one will care if you do

You will like it so much better than stock!!!!!!!

Forget horsepower numbers. It will scream.......You will like the kit. Ya there are better out there . AND THEY COST $$$$$

If you where buying new. And didn't care how much you spent. That is different.

But turbo, for some of your time and effort.

SWEET DEAL!!!!!

Find out what goes with the kit.? I/C, injectors ?????ETC? Or if it is just basic.

We'll help you out. You will love it.

The items listed in my signature line will get you over 200HP, but a person would be foolish to go the band aid rout these days. These are the parts I would suggest to attain your goal.
1. Another vehicle to drive, or enough money in the bank to replace the motor
2. WB O2 ( utilize this to prevent the need of item #1)
3. Ditch the cross over pipe, and install a front mounted intercooler.
4. Throw away the greddy down pipe, and replace it with either a BEGI down pipe, a Tony down pipe, or fabricate your own down pipe.
5. Free flowing exhaust, 2.5- 3
6. Megasquirt, either PNP or home built.
7. 460cc RX7 injectors.
8. Water Injection. Not mandatory, but I am confident that WI is the only thing keeping my internals inside the block.

all a greddy kit needs to hit 200rwph is:

a new downpipe
a intercooler setup
removal of the FMU with a EMS unit
440-550cc injectors
2.5-3" exhuast

You also have to have a WBO2, and know how to use it, or you will blow up everything.
AEM and LC-1 are pretty good.

Just make sure they're high impedance. RX7 stuff fits the bill. Read the FAQ.

I haven't been here in a while. And forgot to change my debit source.
Pm'ed to delete Bean1000 since issue is resolved.


To the guys that have been here for awhile thanks for the appropriate welcome.

To the newbs. IF you don't have TURBO SHUT UP!
AND YES I KNOW I CAN'T SPELL. If I'm in your face you won't worry about my spelling anyway!.

Now, back to topic

I'm not an expert but I have Turbo'ed 3 miatas, SC one. And working on my 4th. With a T3.

IF you have money "by all means" get a different kit.

IF you can BS your way into a kit, like this guy. You would be a TARD! not to put it on the car.

UNless you are a ***** that doesn't like boost.

The greddy has flaws that we all know about. But the difference in power for a budget, is not worth the $$$$.

For a $450-$750 kit used. You can't beat it. You spend a quick small amount and have boost until you save for the kit you want.
Or you can go the slow painful route of buying piece by piece without turbo and GET SICK OF IT AND SELL THE CAR.

And as far as the downpipe issue, take the cat out. Put it back in for emissions.

When you save up enough $$$$ to go commando. Sell the greddy and get the one you want.

But atleast you have boost till you buy or piece together the kit you want.
Or if you just drive back and forth to work, it may be all the power you need. 9lbs of boost makes a miata move pretty good.

By the way "It sucks to be the Knewb"
