some one please explain
 

ok my parts are on there way i am puttin together a t25 setup on a d15 w/an ajustable fmu but i dont know much bout turbos and i am tryin to install this my self. but there are some things i need cleared up, according to the faq i am doing it the "fair" way but to get it to "good" all i need are the lager injectorsand a bigger fuel pump? and i want to go over 8psi so i need the msd do i also need new spark plugs and any thing like that? what else shoud l i know about?

Re:some one please explain
 

i would upgrade the fuel pump no matter what, you can pick up a new walbro 255 for around $90, you need to go with atleast a one step colder plug, and i wouldnt go over 5 psi with any fmu

Re:some one please explain
 

ive seen people that run 15 psi fine with fmu's diffrent injectors BTM and a pump.

Re:some one please explain
 

ive run 12 psi on a fmu before, im not saying it cant be done but its risky....think of it as this, an fmu is a mechanical way to raise the pressure, any mechanical thing can fail at any time, producing a jacked up engine, therefore, youd be better off in the long run to go with some way to tune, i.e. afc hack, uberdata, TEurboedit, crome...whatever

Re:some one please explain
 

Have you seen people run that kind of ---- for years without failures? ;D
Didn't think so.

Re:some one please explain
 

yeah accualy hes been running it for 2 years

Re:some one please explain
 

its set at 10 psi back down from the 15 but it runs fine

Re:some one please explain
 

like i said it can be done, but at some point something will fail, and it will crap out...btw i would put $$$ that says that motor is/will ware out faster than one that has tuning capabilities

Re:some one please explain
 

even if its adjustable?

im running 6 psi with a FMU on dpfi non-intercooled. no problems
