Im looking for 200 whp too

JerryMouse4U 11-03-2009 10:27 PM

I need to crank up the boost on my Greddy

Well I would say ditch the vortech, get some injectors and MS and a wide band, and you should be good to go. There are many people on here making more than 200whp with the Greddy turbo, I was one of them but I just sold mine and am cooking something else up. I just cant stand having parts on my car that I didn't make.

Nice, Thanks for the info.

My sig will get you around 240-250 with aroun. 18 deg at 15psi

Count me in the "Greddy over 200hp club" too. If I had it to do all over again I'd have taken a different path, but the Greddy is a good learning experience since you end up replacing everything anyway.

i enjoy the fact that my greddy turbo hasn't shit itself, probably would have gone though a couple fancy BB GT turbos by now. 200whp is easy to get

miataspeed2005 11-04-2009 10:50 AM

Honestly we are making more whp with our greddy than 90% of the people here. I don't know why people talk so badly about the greddy kit.
If you buy a greddy mani, greddy turbo, a 2 1/2 dp, new hardware and oil lines and IC you could have a pretty cheap and good set up

I got rid of my Greddy because I wanted more power, I wanted to fab up a turbo manifold for a miata and I had a bigger turbo sitting around. So that coupled with the fact that a friend wanted my Greddy all made to much sense to ignore the fact that it was time to build a new set up. Anyways enjoy!

Not only is it a decent turbo attached to a nearly worthless kit which you can find cheap every other week...but that turbo with some decent management, an IC, and a real downpipe and exhaust is the perfect power level.

I'm sitting at a little over 200whp now...and every time I think about turning it up a little I think of everything else I'd need to replace. I can envision tranny exploding, rods bending, the works. 200-225 is a real comfortable power level.

Get the kit, upgrade it, be happy.

Rods bending always crossed my mind but with a 1.6 I'll just buy a used motor for $100 and call it a day

That's what I love about the 1.6L.

Every time I think about a motor swap I know I'll get carried away with it. I'll start with a refresh...then start porting/polishing...and end up forged.

Water injection is just easier than the prospects of another garage motor swap (did one last Nov).

Don't forget you'll eventually blow up your 1.6 differential at that power level. My VLSD blew up after only 2 autocross events.

Problem is that a lot of n00bs get the Greddy new (like my dumbass did) and then end up paying $1300 for, once everything's been replaced, a journal-bearing turbo and a log manifold. So basically it's ok as a setup but sucks as a kit, IMHO.

shhhh I made the same mistake 4 years ago.

Gotpsi? 11-04-2009 10:46 PM

I wouldn't call it a mistake more of a good learning experience.

Exactly what I thought when I had my 1.6 FM2.

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?

brain can build you an ms1 for about the same price as an FIC and you can run that parallel. get the greddy kit rx8 420cc injectors and brain built ms1. for that money, you really can't beat the results.
