i just bought a zpi kit with intercooler and instead of the 16g it has a td05h 20g(bastard 20g) could i run this turbo untuned like the zpi 16g? i dont want answers of people saying to never run untuned cuz ive done research and there are alot of people running untuned on 16g's at 6psi wich is what i want to run....i just want to know if this turbo can be ran untuned like the 16g. any info is greatly appreciated.

 

no it can't it pushes more CFM then a 16G thats the same as asking if a 16G and an 18G are the same its a bigger turbo more air is a more lean mixture and that means.

 

it sounds like your just hoping for someone to tell you what you wan't to hear.

 

thats not what i was trying to get at. im in the middle of looking at flow charts and trying to figure out what exactly i have vs. the 16g. the turbo is actually a blouch 20gxt....im new to boost and just want to get my shyt straight before i go and blow something up

 

Then dont run it without tuning it? Ill be honest, I ran my setup on 5psi along time ago when I was auto untuned, and it ran like ____. Some folks have had decent luck with the 16g on the stage 0 untuned, but its still hit or miss and depends highly on having the right maf holder that was originally used with the zpi kit.

 

Listen hear, This is my old kit, you pm'ed me about this same question, I TOLD YOU THAT YOU CANNOT RUN THIS TURBO UNTUNED like a 16g! Are you hoping that someone will tell you different? I think of all people I would know this turbo and its flow characteristics.

 

^^^haha

answer=no

 

i might be wrong but all of the 16g turbos ive seen on zpi kits r
td05h
a "bastard 20g" is a modified 16g which has been ported and uses a 20g compressor wheel under the 16g cover. can we see pics of your turbo?

 

This is a td05h turbine wheel, but a billet 20g compressor wheel, and it is Clipped AND has a ported exhaust housing. A normal evo3 16g turbo that was used in the zpi kits are rated at 39lbs/min of flow, while this turbo is rated at 47lbs/min of flow.

 

i think running untuned will work assuming u dont run a wg spring and only go wot. any partial throttle and u might lean out. and dont run a boost gauge we all know the more cuts in the vac line the more chances for a leak. you should have a sick dd with this.

 

^^^ Follow these instructions, you cant go wrong.

 

I started reading this, thinking is this guy serious?? Than by the end I was rofl lmao haahahahaha

 

I run a bastard 20g on a ZPI kit and I say it probably is possible but with only like 3-4 PSI. I personally would put the 16g back in if I were to go back to the stage 0 at 6 PSI. I am assuming this is an all original kit minus the turbo.

 

i know what i was told. i have a 16g and this blouch 20g...im waiting on my aem fic but the deal i had fell through....like i said im new to this and would like to learn as much as possible. is tuning the fic going to be something that i should have my tuner do or is it something i could learn and pick up on myself?

 

an FiC is like 300 bucks brand new. if you can't afford that on your next 2 checks you probably are better off not boosting your car. I'd rather wait a month then do it right then put my ish on and have my car go boom then you are saving for a motor instead of a piggy back

 

i would be able to afford it if i wasnt unemployed rite now....times are hard and tryin to find a job is a _____ in my area....im not going to boost till i have management.

 

good question has been answered glad you agree with us your car will appreciate you for it in the long run.

 

20g pushes more air car night not idle right

 

wtf, how would the 20g pushing more error make it not idle right???

 

I think he ment it will lean out on idle but i cld b wrong
