Cranking the boost on a greddy turbo
#2
No one really knows yet. If you have rods in your motor then you might be among the first to find out. Where did you get the rods? Plus youll have to tune it. Im waiting for my upgraded fuel components so and I plan on building the motor so I'll push this stock one to the limit.
The Greddy Emanage has our ECU's altered to an AFR or 13.5. With the new fuel components, I will tune my car to 12.5. At that point I will turn the boost up to 8-9psi.

Same boost as the ZPI kit but you get 50+ more HP with ZPI? That is why I think the greddy kit is weak. Thanks for your time trying to convince me that by purchasing the greddy kit and modding it that I would have a good setup.

Dont forget, one kit is also almost double the price of the other.
Lets look at the two kits without bias.
manifold
Greddy - cast iron manifold which will not break
ZPI - stainless tubular manifold - will outflow the Greddy but SS turbo manifolds are prone to cracking
turbo
The Greddy/Mitsu 14g turbo is not as big as the one ZPI uses but spools fast and is reliable
ZPIs kit makes tons of peak power but some might not like the 3800rpm spool time, esp since our rev limit is around 6k rpm. So that gives us 2200rpm of power?
intercooler
Greddy intercooler is decent but not as big as the ZPI one. After driving 100+ miles the intake side piping is HOT, but outlet side to the TB remains cool. The intercooler did its job.
ZPI has a larger core, but I am not sure who makes their intercooler. I prefer Bell intercoolers...
Injectors
The ZPI kit comes with larger injectors (370cc) where as the Greddy kit doesnt. I bought Celica GTS injectors from ebay for $50.
Emanage
Both come with Emanage, one will be tuned by Greddy, the other ZPI. your choice
Those are the main differences between the kits. I dont care which one you like or dislike, but its unfair to bach one or the other. Both improve the performance of the XB and thats all you should be concerned about. At an average price difference of $1700, some people will prefer one over the other. One thing that is for SURE, is you ARE NOT going to get 181whp by simply bolting on one kit, unless that kit comes with the same intake and exhaust set up as used in their test vehicle.

^^^good points, rollhard.
With the greddy- you pay approx. $45 per horse.
Now, in fairness, lets say that when the ZPI goes production it gives a +25hp over the greddy, but it costs $3500- you pay approx.$50
The ZPI will probably come out a little more than what I'm guesstimating- so $ per horse, you're gonna get the same boost for buck.
The big question will be...how much do you want to spend?
And if anybody thinks that $45 per horse sounds bad--If you are one of those people who paid about $170 for an intake that gives you maybe 4-5 hHP, then you paid about the same amount per horse as the turbo guys- just on a smaller scale.
Personally, I'm putting some real consideration into the Greddy turbo for myself. The numbers are real, they're there- and it's availible now.

Dont forget the 181whp is with their custom straight pipe and exhaust. Im am certain with a new intake and exhaust, Ill make better numbers. Again, I am not endorsing any one kit over the other. Both are good kits. It just depends on how much you want to spend. The power curve on the 1nz with the two kits are totally different too. Greddy's hairdryer turbo makes full boost at 3k rpm where as the zpi kit will boost at 3800 but hit a lot harder.

Alot of people are putting too much focus on Legal/Illegal/Carb/etc and not focusing on the product itself. They are taking a car an safely boosting it to #'s not seen so far...
And in response to the Huge fan comment... Not sure the last time you've been to a dyno, but every dyno shop I've been to uses a big blaster fan to simulate a driving condition and to keep things a bit cool...
I'm really excited bout ZPI and the progress they've made thus far... When the time is right, myself and others will report our real world experiences and either put our foots in our mouths or make believers out of the skeptics..
Good luck to all!

Any one of these kits could be making 300 reliable horsepower on pump gas and expelling helium from the exhaust for all of you party balloon needs. You know what that would mean for someone in California who wanted to drive his car every day? NOTHING. Without CARB certification you have thousands of potential buyers who will never give your product a second look.
So until the CARB questions have been answered that will be the primary, and in some cases ONLY focus of Scion enthusiasts in California. After that has been accomplished then we will concern ourselves with the particulars.

I am sure that the "legal/illegal/CARB" questions don't matter a whole heck of a lot for someone from Texas. But for folks in California it makes all the difference in the world.

Hopefully within the next week or two, you'll see the first two streetable ZPI xb's out there... totally different design than what you are thinking of... stay tuned.. and great work on your kit!

also keep in mind. the motor is small. its a bored out 1.3 no room to sleeve the wall and it can handle only so much. i would love to see internals and a performance head and manifold set avalable.
if honda's B series motoros can produce crazy numbers with 0.1 more in displacement, i think toyota can do it too
