im sorta new to hondas. and defiently new to boost. i have a 92 cx with a sir 2. what im lookin to do is piece together a turbo kit that i can run on stock internals for just a little extra hp. im lookin to run about 7psi and thats it. any ideas, suggestions on what type of fuel management and everything else would be great.
help me
- Thread starter doug piston
- Start date
thats what im doin. im just lookin for some ideas to start my research.
The best way to tune is with a standalone EMS if you got the money and means. If you don't know how to, have a professional tuner do it for you. Next on the list I would suggest doing the AFC "hack." Consists of piggyback fuel controller (usu. Apex-i, V-AFC) used to shorten the pulsewidth of the injectors. Some larger DSM injectors (and resistors) and an ignition retard device (MSD BTM). A rising rate regulator to increase the fuel pressure relative to the boost pressure. A larger fuel pump is a nice addition as well.
But first make sure the motor is in good shape and do the basic tune-ups first. Be sure to change to belts also if you don't know what shape they are in.

i got good deals on parts so i already have the aem system on its way. all tune ups and belts and test were all done at time of swap. which i think was about a month a go. so i am going to have a stand alone system and cheap hours on the dyno. so tuning was never the issue. nor the integrity of the motor.im just lookin for ideas on how to piece the kit together. i was going to go with the greddy kit but all i hear is that there is better out there you just have to build it and i have no idea on where to get the stuff to build one.
i have been checkin out homemadeturbo.com good stuff. and i didnt find a whole lot a setups for a b-series on both sites
check out honda-tech.comdoug piston said:
The Greddy is a pretty good system. The downside is in the "blue box" but since you've got the AEM you won't have to worry about that. Plus it'll cost a bit more than piecing your own together, but it is a good start. Oh and be sure to get an intercooler. If you want to get your own custom kit, lemme know and I'll do a(nother) write-up for you on the parts and things you'll need. Peace!
thats exactly what im lookin for. if you could direct me to where this write up is i would really appreciate it
Okay, first off you'll need all the basic things to get everything started:
Turbo of your choice
Exhaust manifold
Wastegate (if not integral)
Boost controller
Charge pipes
Plumbing and hoses (that would include oil lines, vacuum hoses and water lines)
Bypass valve
Intercooler (sometimes not necessary but highly recommended)
Bigger injectors and fuel pump
The stock Honda MAP sensor can read up to 11 psi of boost. I'm not exactly sure if the AEM could modify and use the signal from the stock sensor but I think it should; stick to that.
A turbo timer is also a nice addition but not required. Boost gauge is highly recommended. EGT gauge is also good for tuning. Various other gauges are nice to help monitor engine.

thanks but my next question is where do i get that stuff. all i see is whole kits. at the greedy website the list misc. pieces but i cant seem to find them anywhere else? also whats the beef with internal wastegates?
i found this let me know what you think.

The G2 site is pretty comprehensive on the basics of a turbo system. You could definitely use that site for reference just remember some of the listed may be for an LS Integra and may not apply to what you are working on. But they still do a pretty good job on going over the turbocharger system. Good luck!

not necessary, if going to use a fmu you dont need bigger injectors or a fuel pump. youl need the fmu, missing link, inline booster.FreeFlyin said:
no, aem cannot do that. youll need a gm 3bar map sensor.
about the water lines, thats only if the turbo is water cooled as well as oil cooled. If it is water cooled, you DONT need a turbo timer. if its only oil cooled id get one.
thanks all for your input
I was referring to using the EMS--Doug is already getting the EMS. Even with that, larger injectors might not be necessary, but remember that stock Honda injectors at redline are designed to operate at 100% puslsewidth. Sure it works to turn up the fuel rail pressure but you'll be better off with some larger injectors and use the power of the AEM to control pulsewidth.SeanMc300 said:
In the case of the MAP, if the AEM can't use the stocker then you'll need the GM MAP sensor.
Sean, I'm gonna have to disagree with you on this one. After a hard pull the impeller shaft is still spinning close to or over 100,000 rpm. Guess what's gonna happen if you turn off the engine and cutoff oil supply to the turbo? "Metal to metal" contact between the bearings can occur, water cooled or not. And the slow drain of oil back into the sump is NOT gonna supply enough oil for that. Also, water cooled or not, the turbo is still going to run extremely hot. Letting the engine idle WILL aid in cooling, keep it lubricated and circulate oil--that means the oil doesn't coke onto the shaft, bearings, turbine and the likes. Don't believe me? You wanna see the pics of my T25 that the previous user didn't give TLC. YES, the T25 is oil and water cooled.SeanMc300 said:
If you don't get a turbo timer, just be sure to let the engine idle for a while after driving.
