GTR Injectors max power??

[sleak]

I hope this hasnt been asked before, I did a seach but couldnt find anything on it.

I have a silvia with an RB20, wolf 3d all the other crap. I have a t3/4 on it now but have a TD06-19C to go on to replace the t3/4. I bought the car off a friend witha blown motor which happened from a company tuning it for boost and made it go bang. anyway, back to the main question,

With my TD06-19C and wolf 3d and GTR injectors (which I am thikning of buying), what kind of power would I be looking at? I dont want to buy the GTR injectors and find they are too small and I have to get something later, or if I upgrade the turbo again later I will have to do the injectors too.

I am sure there are lots of you out there with GTR Injectors in your RB20s, so please let me in on your knowledge!

Thanks alot.

i have known SOHC RB30's to run 10's and produce 300rwkw+ with them.

i have GTR injectors in my rb20 and i have 254rwkw ...

but when im giving it full throttle on about 17 psi

my injector duty cycle says its at 100% so this might be the limit i dunno

unless my avcr is reading wrong

I had GTR injectors in my car, being run by a Wolf, and we made over 450rwhp from them, so that should be more than enough on a RB20. If you want I have a GTR fuel rail and injectors for sale:D

Pretty sure injector flow formula is as follows:

CC of injector divided by 5 x how many cylinders = Max BHP at 100% duty.

So, 440cc divided by 5 = 88 x 6 cylinders = 528BHP.

What is the CC of standard R33 GTS-T injectors?

[sleak]

So you are telling me that in a GTR STD injectors can handel 528hp?? That doesnt sound right to me!! If that was right, why would they change the injectors then?

I read an article once about a guy who put an rb26 in an R31 and was running a T51R i think. He had 300rwkw, could have run more but the stock GTR injectors were maxing out.

What is the CC of standard R33 GTS-T injectors?

RB26DETT - Low Impedence Top feed 444cc

RB25DET - High Impedence Side Feed 370cc

RB20DET - High Impedence Top Feed (270cc - ?)

So you are telling me that in a GTR STD injectors can handel 528hp?? That doesnt sound right to me!! If that was right, why would they change the injectors then?

Rhys

No,

You miss-read one important letter

The formula is for Brake Horse Power, not rwKW.

cbf looking up the ratio but its not much more than 300rwKW isnt it?

[KIL.08S]

i was making 240rwkw with GTR injectors and fuel pump and the car was tuned just into the safty zone (97% duity or something) have just replace the gear for any bigger numbers.

[pnblight]

well from what i have seen the std gtr injector will make around 400rwhp,with everything working well (good pump and fuel pressure ),and i know there is the ability to get a bit more out of them with the wolf if you find someone who likes to tune it (good luck)(just stirring) but i never see the logic in push the limits of the injectors when they all cost basically the same new and new sard can be land for about $120ea new.

So if your looking over 400rwhp i wouldnt bother with second injectors, but if you think you will not exceed that (which is a most likely with rb20) the gtr injectors should do fine.

[sleak]

thanks for that pnblight

I cant see that happeneing with my motor anytime soon, so the GTR injectors shal doo just fine!

Thanks to everyone else for their insight too.

So, 440cc divided by 5 = 88 x 6 cylinders = 528BHP.

Yep, but you can't run an engine with injectors at 100%, you need some overhead for acceleration enrichment and changing weather conditions. Around 80% is a good working maximum.

My rule of thumb in a 6 cylinder engine is injector cc's = bhp

444cc's = 444 bhp

divide by 1.34 for kw = 331 kw

subtract 55 rwkw for 2wd losses = 276 rwkw

or subtract 75rwkw for 4wd losses = 256 4wkw
