hi i have a vx blovk 1.5 with a ex d16z6 headim trying to get 180hp i would like to know how much boost do ineeedthis my set upt25 garrett turbo, 450cc injetors, fmu, fpr, msd 6amp with ss coil, nology cables,with external waste gate,p28 stock ecu.i would like to know how many psi of boost do i need to hit the 180hpand how much power can the pistons ann rods handle.all stock motorhelp

 

The stock engine will be good for 220-240whp, but i'm not exactly sure how much boost it will take from your T25 to get there. One little thing...you should ditch the FMU. Since you have the chipped P28, you wont need anything else.

 

Idk how much itll take but I wouldnt go over 6psi if I were you.

Care to elaborate?? That sounds like a rather ignorant statement to me...

Please go on.D's are the toughest motors honda has made, and they love boost . I say 10psi minimum.

I dont think i'd go that far, but stock Honda motors are not the weaklings that people think they are. Furthermore, psi really isn't a factor anyway. The engine will crap out at a given power level regardless of the boost needed to get it there (discounting extenuating circumstances such as detonation, etc...)

 

Just goin off on what happened to my friends d16. Given that his was a completely different setup... He was running 5psi with no problems... decided to retune it and bumped it up to 8psi... bye bye motor. Fully built and boosted GSR motor now so who cares.

 

i'm goin to get it tune
but i don't really like those manual boost controllers
i'll prefer a spring.
but thanks a lot guys

You speak the truth sir

 

so what you guys mean is that i shouldn't go over 5 psi tuned

This is what i was hoping to hear. Now i understand why you made the statement you did. The point is, PSI really isn't a factor. There are several people pushing 20+psi and making upwards of 450whp on stock blocks with the right setup and tune. I didnt make any record with my stock GSR, but it did last 2 years at 315whp

 

but you are talking about a gsr motor compare to a single cam is a big diff
all im trying to get is 180hpw right now im runnin at 5 psi but it doesnot feel good
like around 150 some like that

 

try 20 pounds , then lets us know if it hit 180 hp

 

dont you have something better to do than talking S**T

God I hope he's kidding....

Unless you like rods going through your block, keep it at 7PSI or below with a GOOD tune...

 

just a joke , relax. do 5 pounds to be in the safe side.

 

go to j-k-tuning ditch the g*d damn fmu

 

Well I'm going to say around 11-13psi for 180whp. My reasoning, the t25 is close to a 2g eclipse 4g63t turbo (stock). In stock form they have 200hp on 10psi. Im thinking If you take the turbo off it will have 140hp like its 420a n/a eclipse brother. So thats roughly 10hp/psi (at the crank im guessing) and i would give it 7hp/psi at the wheel. Set that on top of a mini-me with say 100whp and you would need around 12 to hit 180whp. Thats my thoughts and reasoning. Although that turbo is similar and the 4g block is a 2.0 not a 1.5 .
