Default need advice if i should upgrade greddy?

I know i'm bugging everyone with my multiple questions about my miata but bear with me. I've got the 1.6L greddy kit on my miata and I just order turbo tony dp for it. I just realized that i need to rebuild my turbo (oil leaking in the turbine). I read that doing so isn't hard at all and i can get the kit really cheap from http://www.gpopshop.com/ but what i would like to know is if it would be worth rebuilding my kit or upgrading? here's a list of what i got

greddy kit
rc 440cc injectors
ms
IC piping with FMIC
motor thats about to blow but i've decided to spend the money to rebuild it with rods pistons etc etc.
turbo tony dp
2.5 exhuast

I mean hell...why not just rebuild the turbo, its not the 'best setup' but you already have everything to why not just use it?

With that list I would upgrade to a FM/BEGi mani/DP combo and make the existing stuff work with it. Especially since you are rebuilding the motor with better internals, might as well make use of them.
Do not rebuild that turbo, save up some money and get a bigger turbo used to go with your better mani/DP combo. What clutch do you have and what exhaust do you have. Are you still on the 6" rear end?

so i wouldn't use my dp that i ordered from turbo tony if i upgrade? I've got a cheap ebay clutch that i purchased 2 years ago but i only put 200mi on the miata since then (it's been down most of the time), but i'm not to concerned about it because i'm thinking about doing a 6sp tranny swap and i still have the 1.6 differential

NOt sure it would fit with your bigger turbo and better manifold if you get it.

Not very efficiently, I think the most guys are putting out with greddy is 250 tops. If you want more than 250, you are best of with a bigger turbo, most greddy guys upgrade eventually, ask Vash. lol he just did.

Your looking at topping out around 250 w/ the greddy turbo. That should be around 15-16 PSI. Maybe you should take it to that level and decide if you want more. 250 to the wheels in a miata is good enough for some... plus your looking at a serious cost investment when you start talking new turbo. I see that your going to build the motor, so maybe do that and run the greddy kit for awhile until you save up money for the new setup.

Rough setup-
manifold/dp/turbo ... couple ks.

i'm guessing that 250 would be my limit. but you never know i'm going to order the rebuild kit and fix my car to what i want it to be and if i feel like i need more power then i'll upgrade

IDK, the wastegate fails, but Ben is making like 257 or so at 16 psi isn't he?
