you don't need to max them out like :confused:
a lot of lads do 740's instead of 550/555 just so the 555's wont be maxed out, and loads of room for more mods like... correct me if im wrong but havin 740 at say 60% duty is better than 555's at 80 while you're given the same amount of petrol into cylinder ? :confused:

yes lad u be right in whatt ur saying, reduce th duty cycle of the injector so it wount overfuel etc.

WTF man!!!! im trying to get these for that reason alone :D
and they will go nicely in the rb25 im building +2 more at about 120 a peice

not gonna argue wit said tuner but that would be my logic???

As I have explained to Darren the 550's will be fine up to 400 bhp. He only wants 350 bhp so 720's which are good for 575 bhp are overkill. Also it's not the duty cycle that the problem it's the atomisation of the injectors. The smaller the injector the better the atomisation of the rule the better the cleaner the bur of the file for a given power. 720 cc will work and can be mapped but in our opinion on a STD engine there is no need for more than 550 cc.

When it comes to RB engines the rules change allot. On a RB 6 cylinder engine 550ccc will do 520 bhp safe so unless it's a real serious drag motor then we would not go near 720 as they are too big. Also RB engines are way more sensitive to the Injector atomisation. This is why the cheap reworked STD injectors are so shit in them.

Are you serious about the Intake ? Probably one of the worst mods you can do to RB20 or 25. The real one is designed for drag only. It will kill all midrange torque a drive ability of the setup. Never mind the shit Chinese bad copy.

The injectors are very good and cheap but dont kill the car with an E-bay fake inlet..

Is it true Robbie that the standard up and over manifold on the RB20/25 is actually pretty good for its application?

Yep it's very good up to about 450 bhp. Then need a bit of mod ding to 500 and over 500 the greedy might be needed but it kills all torque.

We are working on a kit for the STD manifold so it can take top feed injectors an rb26 rail and make more torque.

yes seruios it cleans up the engine bay no amount
it needed a bit of work to be perfect bit of polishing and die grinding on the inlets etc
tat mod and e85 wit less boost than petrol and i increased torque by about 60 foot pounds

60 ftlbs at what rpm. I presume you are talking about the same turbo same boost same ign timing ? If not you can't compare.

I would have thought 740cc and adj fpr would have done but like always its good logic you work off, thanks

Ye might want to stock up on the E85 or take a trip to enfeild / ashford for a remap as i heard they are using the last of there stocks of E85 and there will be no more imported always the way
could you imagine shell optimax now the price if they still had it €2/L??

As for the g-ready inlet met a guy last sun in mondello 4dr R33 with a rb25 on 1bar boost, replica g-ready inlet @ "420brake on std internals" which is dancing/sliding:D on a fine line
personally im cheap and good using a std one pollished as far as the dremil would reach and a p+p head and wish list was a gtr inlet its the back up to my sr20 since all the di crew have raped the 1jz engines

of topic or what:eek:

dunno wat rpm was at think it was down low not really sure thou
changed from petrol to e85 and advanted the ignition timing
