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

thanks it sounds like you realy know your stuff, i'll post pics & details after i install 8)

Re:stock fuel injectors in a b16a civic 99 si
 

um he ownz the site lol......


you can find a used sylvia turbo to fit that manifold on ebay..

japandy has em.

Re:stock fuel injectors in a b16a civic 99 si
 

i knew he owned the site, it was a compliment & i don't think you have to lol. im gonna have an adapter flange built
cause the t25 is in awsome shape. ;D

Re:stock fuel injectors in a b16a civic 99 si
 

dude trust me, dont buy a t25, its way to small, once you spend the money to fabricate the manifold and down pipe just for that turbo you will drive it, and trust me it will feel fast at lower rpms but from 6-8 you wont feel ----, its not worth it to waste your money. i have a T3 and im not happy with the results, wish i went with t3t4 hybrid.

Re:stock fuel injectors in a b16a civic 99 si
 

i mean you already bought it so sell it and buy your self a t3t4
