I've been running about 9 psi on my civic jdm d15bfor abotu two months, the previous owner ran 9psi when he raced, and i just drive usually in vacuum but when i'm passing ill go about 5 or 6 psi. If i'm practicing my launch i set my boost controller to around 9psi, how long do you think my internals will last?
I want to change all internals as soon as I get the money and run a bigger turbo, (16g EVO III) right now i have a 14b.
What do you think? It sounds really nice at high psi, hearing the turbo whistling lol I lvoe it but I don't want to ruine my engine.

 

9 psi is fine. The turbo is small so its not pushing a huge volume of air.

 

^^^^yeah, you should be fine since you're running a small turbo. The d series can handle around 210-220 whp safely on stock internals, so on 9psi on a 14b you are still below 200whp.

 

What engine management and fuel system upgrades are you running?

9psi with that turbo and a solid tune should be fine. Just be damn sure you've got good afr's

 

agreed with all of the above and a e3b16g turbo on that car will FLY w/ a build bottom end pushing 10-12psi. you'll prolly need somewhere between 480-550cc injectors for that kind of setup.

 

Ya I have 460 cc Rx7 injectors

 

Also how much hp do you think I have? The previous owner sayid "Dyno #: 160 WHP/150WTQ @ 9 Psi (these #'s are WITHOUT VTEC .. low cam)
*estimated power in high cam is around 200-220whp* "

Engine mods are:
LSD transmission
P06 chipped for Uberdata
JDM D15B VTEC
TE04H Turbo
about 9 psi
Magnaflow Cat-Back Exhaust
MSD 8.5MM Super Conductor Spark Plug Wires
Spark Plugs (G-Power Platinum) 4-Port Aftermarket Vaccum Bar
460 cc Rx7 injectors (low impedence) with resistor box.

I'm looking to do as many more mods as I can, before I get the internals and everything done. what I've heard of is underdrive pulleys, bigger throttle body, walbro fuel pump, and a bigger throttle body spacer. Is there anything else I can do before I do cam, valve springs, and retainers? After that I'm going to do pistons and conencting rods, all done professionally because I can't do my own work, I might get it sleeved if I have the moeny aswell. What else is there to do?
Thanks everyone

 

you will need the fuel pump so you can get that... it's relatively inexpensive. if ur gonna be building ur bottom end to run more boost you'll want to tuneit... so i'd also get a wideband. i'd personally do the bottom end before the head but that's all preference.

 

Which parts consist of the bottom end?

 

connecting rods, pistons, piston rings, new oil pump, and new bearings is the basic
