one more question, what psi of boost does the zpi stage 0 run out of the box? because I understand that I need injectors and a piggy back, but I am only going to run stock tune and injectors for a few weeks.... finacal reasons... but I will be intercooled

 

I would suggest you ask whoever you are purchaseing the used ZPI kit from...you know that ZPI is out of business and you can no longer get their kits used, right?

Oh, and "Don't boost on a budget"

 

The Stage 0 ran on 6 PSI out of the box. There were people who ran them for months as is, before craving that extra power. So, as long as everything is in good working order, you should be good to go.

 

Yeah, but new, the wastegate came with like a 9psi spring and you had to swap out the 6psi spring during install, right?

 

That is correct. One of my freinds did the swap and i remember it was the biggest PITA!

 

so long story short, you can boost up to 6 pounds safely?btw i am not buying a used zpi kit, I am merly using them for reference, I want to run the turbotoyota basic kit

 

Correct. You were given both springs.

 

firstly, if you have not already purchased the basik kit, Todd is planning to discontinue it. Secondly, The TT kits and the zpi kits are WORLDS different...NO WAY you could run that larger turbo and EL mani on stock injectors and no managemnet. Not all turbo kits are built alike, bro.

I have the TT standard stage 1 kit and was boosting 4psi for one or 2 weeks on stock injectors and no management...ran DANGEROUSLY lean.

 

Yeah, can't compare the two that easily. The ZPI Stage 0 kits did the opposite, they ran RICH instead of dangerously lean.

 

so who makes manifolds for the 16g turbo that you said will allow me to run rich?

 

huh? TurboToyotas has as "ZPI Replacement" manifold that will work witht the turbo from the ZPI kit, the 16g.
But it was the actuall ZPI kit that would run rich with no managmenet...the TT kit replaces the mani and all the IC pipeing, so it would effect the richness...

 

running too rich/running too lean = Bad Motor

Have you bought a kit yet?

 

no but I think I am going to frankinstine a kit together, megan racing mainfold and downpipe(only set I could find), tial 38mm wastegate(already have it), greddy bov(already have it), huge front mount intercooler(already mounted and installed, that was a _____ to fit in there), and since the megan racing manifolds are only compatable with a t3 flange, I think I am going to go with a t3/t4 50/63 turbo, unless you can sugest some thing better, I am going to go ahead and purchase everything else I need on friday, minus fuel management

I have heard that some of the Megan manifolds and downpipes fit for crap

the T3/T4 is always a crowd pleaser on here. lots of people are running them

 

i would say to buy this one on here

you can alwyas get a set from turbo toyotas...atpturbo has a nice setup too...

 

he already PM'd the seller on the thread I linked

 

Running to rich = bad plugs, gas, and horse power.

Running to lean = KABOOM!

 

What size is the Turbo Toyota intake 3"? and what size is the stage zero intake 2.5"? I think the way the 2 kits run is due to the maf placement. I have a custom 3" intake with the injen maf holder from my old intake, and my car stumbles and the a/f are all over the place when I let off the gas even with a fi/c.
