stock fuel injectors in a b16a civic 99 si
 

;Dhow long do you think my stock injectors will hold up with a 10 or 12:1 fmu & a 225 walboro in tank fuel pump running 6 p.s.i.?

Re:stock fuel injectors in a b16a civic 99 si
 

3 days? 3 months? 3 years? who knows... we dont know how well your injectors are right now.. It should be ok, maybe a tad on the high side with that ratio, but your not running that much boost. You could always start off with a smaller spring, and work your way up. (or vise versa)

which fmu ratio should i use? i'm installing my turbo on the 17th ;D i have an hks manifold, 98 eclipse t25, eclipse 2g intercooler,
tyfoon bov, vortech fmu (which is all i have for fuel management right now) with all the disc ratios, & a 255 walboro in tank fuel pump. the car is a 99 civic si b16a with stock internals & stock everything else. i want to run 7 psi. i'll take pics & post them after i'm done, along with my setup. i know i have to retard the timing .5 degree for every 1 psi & i have to gap my plugs acordingly. i'm new to this site & to boosting & i think
both things are f**king great. thanks.

hks manifolds work with t25's?

Re:stock fuel injectors in a b16a civic 99 si
 

i would go with the 12:1 fmu, and i dont think a 255 lph fule pump is neccesary , the vortech supercahrged b16a2 kits come with 155 lph, and a t25 is kinda small, i would go with t3/t4, i have a t3 with your same car and it has alot of torque but it doesnt feel it pulls as hard at higher rpms

Re:stock fuel injectors in a b16a civic 99 si
 

Agreed, the T25 is to small for the high revving B16a, I would be looking along the lines of a T3/T4 hybrid turbo (smaller spec)

The HKS T25 manifold uses the JDM T25 Nissan Style Flange, basically the same thing as a Greddy flange, So a DSM turbo will not fit on that manifold..

thanks alot for the replies. i'm gonna use the t25 & i'm gonna have a flange fabricated so i can fit the dsm t25 on the hks. i'm gonna use the t25 cause i already have it & it's in awsome shape. will the t25 stil make descent horse power on a b16a? can i fit a t3 on the hks manifold?

Re:stock fuel injectors in a b16a civic 99 si
 

i'm only gonna boost 6-7 psi. w t25 in b16a. 8)

Re:stock fuel injectors in a b16a civic 99 si
 

It will have good torque and spool very fast, but where the B16a is efficent, the T25 wont be... Exampe 7500rpms and above+ (where the B16a makes all its power) so.... you will and you wont like it.

No the DSm flange is different than a T3
