So i know that ZPI is discontinued and all that but i was just wondering whats the biggest size turbo like 16g,18g,20g you can go and still be safe with your stock injectors and whats the most psi you can run? im guessing its only like 5-7 psi and 7 being on the very edge of having to change injectors?? Also do you have to have an engine management with this kit or isnt it if you run like 5 psi you dont need one? I have searched all over really and havent beenable to find my answers fully..Dont worry ive already made my turbo kit!! lol

 

No comment. If you really searched you would have found the answers. Stay with 16g with stock injectors with no management on 5psi.

 

^^ X2 there are tons of threads on the zpi stuff. use google too

 

do not go past 6psi on the 16g on stock injectors or stock ecu

 

oh what the heck just slap a t88 and boost pressure to about 26-28psi (keep it under 30psi for safety) youll be allset as long as you have the trd ecu flash =P

 

nahhh i think ima get a 1.1 a/r and run 35 psi on stock internals with my homemade carboard box ecu!!

 

Well its been 3 years since my tc has been on boost with stock injectors and stock ecu, 6psi daily driven. so 6psi you should be fine.

 

What exactly is your setup? Are you running it with or without an intercooler, etc?

 

basic stage 0 kit with intercooler thats about it. stock exhaust also

 

i believe this was my old kit. thats awesome brammi!! im glad everything is still running strong.

 

yup it definatley is

 

im on a zpi kit but before i urgraded to a 20g i ran an 16g with 440 for over a yr no problems.

 

i heard about u but never seen ur car there a few boosted tc that hang out hit me up maybe u could come by.

 

Where do you meet up?

 

pm me ur number today we meet up off of 75 and pines we gonna hang out again tomorrow

 

actually we should make this the new official zpi thread since the old one is half about how zpi went down and how kenny screwed everyone...lets just keep this kenny free to help members who are digging up these kits and have questions. finding info on the old thread past the first page is nuts lol. I gave up on finding my charger and decided to buy a dslr within the next week so ill get some pics up of my kit for those who are still stumped on IC pipes.

 

This is good to hear, I'm about to install this same kit

Sounds like I need to upgrade

 

for you guys running stage 0 add an intercooler it makes a big difference.

 

Definitely - I can't find the post but I recall ScionDad finding the intake temps were reaching 170-180 degrees F back in the day.

Speaking of which How are most of you ZPI guys clocking the 16g for intercooler connection? I heard straight down it faces the block and transmission so some use a J-pipe and keep it clocked straight up. Others clock the outlet forward and switch to slim fans to make space. Any tried and true methods on this? I'm thinking of getting the Dezod pipes but this missing link has me concerned.

 

mine is facing as far down as it can go it hits a grease fitting. i also have the dezod IC pipes.
