Need help, SR20DET injector upgrades...

[boo2]

anyone here knows how to upgrade sr20det injectors?

 

[dorifto_deMoN]

the easiest way : go to any performance shop, pay thousands of ringgit
for a brand new sets of injectors.

the not so easy way : find a set of s14 or s15 injectors. usually very hard to find.
unless your engine is already one of those.

the cheapest way : add in a couple of extra injectors.

upgrading sr20 injectors is something hard to do if you are running on a tight
budget. cause it is side feed type. not the conventional top feed like most of
other engine do. try to avoid doing modification that requires you to upgrade
your injectors. based on my experience.sad sad story. gud luck.

thanks for the tips bro...

anyone selling s14/s15 injectors?:boring:

I have one spare set of Injector from S15 , PM me if you are interested. Price wise, i guess most are selling about RM 500 . Let me know. THanks

i haf an extra injector controller wif 2 injectors.. previously used in my car, now using larger injectors only.. pm me if interested

AFAIK upgrading injectors can't be done just like that. You will need to re-tune your ECU to work with the new injectors, or the engine won't start, or at least that's what I've come to believe.

S13/S14 injectors: 370cc
S15 injectors: 480cc
Nismo injectors: 555cc or 740cc

I would suggest getting the S15 injectors, as they are relatively cheaper than the Nismo ones. I plan to get a set sometime next year, along with an Apexi PowerFC :D

 

[Temujin]

true, u need an tuned ecu able to use the larger injectors..

 

[dorifto_deMoN]

yeah..forgot about the tuning oledi. at least a safc would help. sorry. btw, temujin where do you get those big injectors. how much is the flow rate.

 

[DinNismo]

Cheaper.....RB25det injectors....

 

[dorifto_deMoN]

rb25det injectors...??? oh yeah, they are side feed right. but how much is the flow rate. btw, dinnismo, saw your car last month at mr2 before the makro cheras exit. you were right behind me. look from my rear mirror and instantly saw a mean r32 front wth a huge intercooler. muehkehkeh.

 

[Temujin]

most shops in sunway/old klang road would haf the big injectors.. i'm using 850cc sard ones.. it's an overkill considering the puny output i'm making.. but better in the long run if i'll be making more later ;)

use AIC la.. unless of course the gila kuasa blood runs in ur veins, then get a tuneable ecu 1st, then larger injectors.. :)

I have to agree with Temujin with this.

I would think about what the car would be for. Drifting? Drag? or just plain old street racing. Since you won't need such a powerful engine to drift, 480cc~550cc would be enough.

i looking for that range ler. not so high up like temujin`s using (gila kuasa). about the ecu part. already have my car equipped with microtech. muehehehe

Anyone know where to get side feed injectors for RB25det? BTW whats the injector CC for RB25det?

 

[dorifto_deMoN]

found out that rb25det injectors is the same as sr20det red top injectors. it is 370cc.

 

[chriiz18]

thanks thanks....arghh very hard to get after market stuffs for RB25. Anyway Thanks Demon.

Holy crap. 370cc injectors in an RB25? That must be why it lacks power so much..

 

[DinNismo]

6 bro... 6pcs of 370cc injectors..

 

[MizuChi]

I know. That still means it's getting 370cc per cylinder. The car is heavy to start with anyway, and obviously 250hp just doesn't cut it.

 

[dorifto_deMoN]

dunno about the power delivery for rb25 cause never test it yet. ask all the sifus around here for rb25 injector upgrading le. or u can put extra injectors. plus injector controller. plus ecu plus plus plus.. muehkehkeh.
