I recently bought a used ZPI kit with 410cc injectors, intercooler, and a FIC.
I'm not really interested in making a lot of power. I just want to get a little more out of the engine while still making it a DD.

My question is, is it really worth the money getting the fic tuned for that little of boost?
Or should I go a different route? (ex. splitsec enricher or what have you)
or even...does anyone have a map for that little of boost?

I dont really see many low low boost builds, so hard to find info on this.

Thanks!

 

let me help you out before you get the snot flammed out of you. this is a question we get asked a lot and we usually are prettty rough on people for it. now with that being said.

There is no easier way to say this other than the life of your motor is dependent upon the quality of your tune. so yes it is absolutly worth getting it tuned for "that little of psi"

also i don't see why you are worried about that low of psi. i personall used to DD 10psi on my old kit. there are people who DD 14 psi. most common is a DD of 8psi. all of us have strong motors. still. ____ Travis (rhythmnsmoke. sorry if i messed up spelling you name travis i always for get how it's spelled.) has been DDing 8psi for almost as long as he has had his tc with no problems. 3 psi i dunno if it will do much power wise other then cause lean spots in your motor so it can blow up.

 

exactly what he said. idk what the max safe psi for a safe motor is though, just dont go over that and youll be good.

 

your good if its a 16g on 3psi

 

up to 6psi

 

psssh the real fun starts at 30 psi But anyways, on topic, no matter how much boost, you NEED a tune, not optional. Youre converting an N/A car to F/I. Boost wise, I wouldnt waste your time with 3 psi, Id run 7-10psi. As long as its properly tuned, itll be perfectly safe.

 

Nick by fun do you mean rebuilding your motor once a month? lulz.... don't taze me bro.

 

its really a matter of opinion. yes is can be done with all original zpi parts....STAGE 0! not an intercooler or different turbo. it has to be the 16g, stage 0 piping, manifold, and wg. and dont go over 5-6 psi. there are plenty of people who have done that without a tune. there are people who will tell you anything over 0psi you need a tune, and there will be people telling you stay below 6 psi without a tune. personally ive ran the stage 0 zpi kit on 5 psi for a few months just fine. i wouldnt recommend doing that long term. but yes, to answer your question, 3 psi is like barely anything. but things do happen remember.

 

Thats exactly what I meant lol Im completely used to my car being in the garage with no motor in it more often than it actually runs. haha

 

 

travis ran 8.5 psi for like a year then went to 10 to 11 to 12 over 3 and half years and he told me every day he beat on the car and then blew his $hit up for $hits and giggles across the street from his house on a two step threw two rods and then moved onto a ptuning rs kit but regardless it lasted forever with allot of boost so get it tuned right and maintain everything and you cant go wrong.

 

Get the car tuned don't _____ out n go 3psi that's worthless might as well go supercharger if ur going to pull that off lulz I ran a zpi stage 1 14psi dd n I beat the ____ out my car n it was great but I got tired of the tiny turbo n now for the past year n some months been running descendant its a good start but get tuned for at least 8psi

brett you have started only replying with MEME's bro. do you plan on ever using your keyboard again?

 

PSI is a relative term. A 16g turbo might make 220whp @ 8psi, where as a GT35r might make 300whp @ 8psi(These aren't true numbers I am making a point). How is this you might ask? Think of a coffee stir and a straw. You can move more air through a straw than a coffee stir. It is about the amount of air you can move. 1psi is the same if it is in a 20oz soda bottle or a 2L soda bottle. The amount of boost is the same, it can move more air which lets you make more power. Now other things can come into play like IC efficiency, tune, and exhaust. The tC has a very strong engine it can handle the hp if tuned correctly. I believe the highest HP stock engine had something like 430whp.(Someone correct me if I am wrong) People run 300whp all day long without issues. I have Slydrin's old kit and I am shooting for 280whp(2.5inch exhaust and 2.25 axleback). I DD my car and have 64k, I am also having Dezod tune the car. You could tune yours at 8psi and if you are worried just pull more timing and add more fuel like I am and make less power.

 

while technically right the term used is CFM psi is psi. its compressor wheel efficency that you are talking about and how much CFM the compressor wheel is moving at a certian RPM.

There is only one thing left to do next (engine wise that is).

 

your engine isn't built yet is it Travis?

 

Oh the things I would do if that were the case.

I have the vision...some things I'm working on though that have to happen first before I can get there.
