I dynoed my "authentic" ZPI kit (16g) at 7lbs of boost, making 250whp/260wtq and that was with a tune in the 10s A/F ratio, so it's not the 16g. The 16g will do 280-300whp at 10-10.5 lbs of boost.

 

Yes after smashing on the 16g for so long, I had it rebuilt into a tdo6 20g and ran than. Very nice spool still. But you don't have to stop there, you can get a 25g also. And I'm pretty sure that you can get a 3076 witha DSM flange on it.

 

okay im go ahead and try to see how much i could make on a 20g. now the hunt is on for a new turbo lol

 

iam pretty sure that you can put the 18g and other turbos like that with the zpi kit. but i believe its a different manifold. but iam not 100 percent sure on this one. you guys are right it has really fast spool. the tune was also a safe tune. which scrificed power but i have no way of blowing the motor or anything. its a touch on the rich side so it doesnt surprise me that the power is a little down compared to other zpi tubo kits

 

this thread is hurting my head lol....if u were local id say u can have my zpi manifold which is sittin in my car with a blown motor for months now....noone will buy my car for 4Gs lol so im stuck with it...but i made 293whp on 9.5 psi....for 40k miles then it blew at 110,000 miles...if u wanna take the drive up here u can take my mani and whatever else u feel like dissassembling for dirt cheap

 

i have a real zpi kit. the amount of power being pushed out of the car also depends on what computer and what tune you have. i have the greddy emangement computer.

 

4g's huh....blown engine huh....hmmmm...every thing comes with it? kit?

I cant buy it but maybe a friend of mine could. pics?

 

yep full turbo kit and turbo back exhaust (2.5 inch) wotbox and management...just needs new motor...and it has tein stecs and hotchkis front and rear sway bars...b&m SS and twm bushings...trd clutch and ill even give my dezod energy motor mounts with it

 

ok im gonna bring this back to life because from my understanding...the OP has a zpi stage 0 with 440 cc injectors and he thinks hes running 17psi.....im trying to explain how impossible that sounds but i dont seem to be gettin thru to him....his tuner says hes tuned for 13psi....but heres a twist he has a built bottom end....compression ratio is 9:1...chime in please

 

His HP #'s and the PSI numbers just dont seem to match up.
If its a stage 0 could you imagine how hot the air is at 17 psi with no intercooler?
440's dont seem to be big enough injectors for that kind of psi

 

this is wat i told him but he says he has a tiny air to water intercooler...

 

and he said its more efficient then a front mount...idk.....it looks like a resonator on the charge pipe....

 

I don't care if he has a water-to-air intercooler the size of the Hover Damn, 440cc injectors do not flow enough for 17lbs of boost on any turbo 16g or larger. I was maxing out 550s on 10lbs of boost. Cooling efficency don't have anything to do with adequate fuel supply. You should ask him what his injector duty cycle is.

 

bro i tried explaining but he insisted that his boost gauge read 17psi....i told him theres no way his car still runs...lol....idk man i wish he would repnd on here cuz i need his input
