    hello people , I wanted to ask how many whp I can take out from my engine and be safe at the same time .

    I have this:

    b16a JDM
    stock sleeves
    eagle rods
    wiseco pistons forged
    Turbo Kit - t3/t4
    2.5 inch exhaust pipping
    TiAL 38mm wastegate.
    450cc DSM injectors
    Walbro fuel pump
    Tunning with CROME PRO.

    I am currently with 282whp and 193lbsft of torque at 10psi , I know that at this point I need to change injectors but I dyno it last week, Im installing this week the walbro too. my goal is probably 350whp , a little less don't hurt ! , thanks in advance for the help.

    It wouldn't hurt to put another 6psi ontop of the 10psi your running now, should get you to your goal if not a little more. Just upgrade the fuel system to compensate for the increase in boost, and have it dyno tuned again.

    I would start to worry about using the stock head at that kind of hosrepower, I would atleast get a mild port and a 3 angle valve job. Did you install some arp head bolts?

    I have stock head bolts , I was thinking about installing cometic head gasket , arp bolts , and 750cc injectors !! and start from there , what do you think ?

    atleast get arp, or I guarantee your will get head lift after a while, the stock head gasket is fine. but if you do decide to replace it I would get atleast a mild port and a 3 angle valve job

    350-400 is about all the stock sleeves are good for isnt it?

    I know stock fuel pump wont work , I realize it when I was tuning, I installed a bigger one , but don't know the brand, and that one worked good for a while, but I already bought the walbro , cause I want to be sure of what I have , I am installing it this week,

    So buy list is ARP , cometic head gasket , and injectors ?

    B16 blocks are crappy for all motor setups. The most NA power ive seen out of a b16a was 200whp, and that was with some SERIOUS head work and cams not to mention the higher compression pistons.

    Boost on the other hand is a different story. You can boost a stock b16a engine with a t3t4 50 trim and make 250whp tuned on 10psi. Thats some serious fun on the street, but I prefer something along the lines of 350-400whp for the street, IMO.

    I have a question about all this , I have seen people with 12psi and with hp not even close to what I got, using similar setups (forged pistons and rods ) , I have a friend that dyno tuned he got 266whp at 12psi , I believe that if I put 12psi I get at least 300whp, cause I made 282whp at 10psi , and I am talking about the same engine (b16a)

    People , I need it to add something , I know is not directly related to the subject , but I was changing the fuel pump and I took some time to check my injectors, the guy who sell those to me told me that were high impedance ! , and I believed him (big mistake) , yesterday I was checking Ohms on the injectors and apparently they are low impedance (3.5ohms) , high impedance should be around 12ohms (correct me if Im wrong) , so there is two things I wanted to check ...

    1st : I bought a Si 91 civic resistor box , it has 5 wires, one red , and 4 black, the 4 black should be connect it to the injectors (yellow/black) , and red should be connected to only one line that comes from the ECU ? , having in mind that there are 8 wires total, 4 wires that comes from the injectors(yellow/black) and 4 wires that comes from ECU ( I Think , lightyellow/black ) , 1 from this last 4 is real signal (ECU) and what are the other 3??
    I install the box this way : all 4 wires (comes from ecu lightyellow/black) all togheter to the red wire on the resistor box, and the 4 black wires directly to the injectors (yellow/black).

    2nd: I used those low impedance injectors without resistor box for more than a month , I know that can be fatal for the ECU . but is working now no problem aparently , is the ECU ok ? or even if it's working , could be damaged by now ?

    Some setups can operate your way without a problem. To be perfectly honest with you, if it were to burn out the ecu, it would have done so within roughly 10 minutes.

    *If you look at the specifications of the injector driver package, it indicates it can flow the amount of current required for low impedance injectors.*

    Are you running an aftermarket Fuel Pressure Regulator? If so, what brand and type of FPR is it and what does the fuel pressure rise per pound of boost?

    I know psi is not a good base to say how much power you are going to get , but the difference is too big !

    the only thing I don't understand from yours is that only one line comes from the ecu to the red wire on the resistorbox , in my case I have 4 (obd1)
