Now...i need to know what size injectors to get...and what company!

Are injectors injectors? or is one brand better than the other...

i was thinking 96lbs MSD ones but i'm not sure if they're any good...or if they'll fit perfectly. all i know is that they're half the price of RC's....

is this a good size? or is it overkill...i want 500whp.

Arturbo

No offense to your dreams and such, but unless you are going full race why do you want 500whp? I really dont see the point in getting 500whp. With 300-400whp in a street honda is more than enough to beat 95-98% of the cars out there.

Maybe its because Im old and I only have 277whp. Our race car is over 600whp and I cant imagine driving that thing on the street...

But follow your dream and dont let anyone get in the way of them, but man 500whp is alot...

Ltech

Yeah 500 whp is alot. I;m going for 350-400 whp on my b16. But good luck though.

ekb18c

If you know as much about the parts you just listed then you should know what injectors and size to use.

kidkutz

okay...i want 500whp because i want to break certain times. I know of two preludes that are turbocharged and they dyno'd at around 400 HP...both are hitting low 12's high 11's...you have to realize that my prelude weighs almost 3000 lbs and big HP is what i think i need to achieve my desired times.

ekb18c: if you wanna say something come right out and say it...why should i KNOW what injectors i'm going to use based on the parts i've chosen? First of all...i have an injector size in mind...but i wanted peoples opinion of whether or not they'd be overkill...or if anyone suggests a lower sized injector that will still help me achieve my goal. i figure with a comment like yours...you must have a lot of technical knowledge...well why don't you help me out then instead of being an ***? if you don't like the way i posted my mods then you can kiss my ***...i actually thought twice about posting it all too...but i figured with a topic title like mine i'd be asked what i had done...this way it's all said and done...and perhaps someone could help me out based on the info i provide...

boosted hybrid

At least 720cc, although with 500hp you are probably going to max those out. 900cc is the way to go, you will be guaranteed to run lower duty cycles. Try denso, i have seen 900-1000cc injectors for a set of 4 run 800.00 on the internet. I picked up a set of 720cc denso's from http://www.roadraceengineering.com for 450.00 with the o-ring pack. I dont know what the aem ems capability for injector size is, you might want to look into that before you run some monster size injectors.

kidkutz

thank you. i ran the rc engineering formula on their website and they recommended a 1000+ cc injector =P was just making sure that this was correct and that someone else recommended that too.
I've never tried Denso injectors...any good? Best prices i've found are $94/each for MSD 96lbs...and $150/each for RC's. Other than name...are there major differences between the brands?

boosted hybrid

RC are lucas disc type which can run at higher duty cycles (95% consistently). I dont know what the MSD brand injectors are, but i have heard good things about them, although fitment isnt supposed to be great...again not first hand experience just what i have read and talk to ppl. I like my denso's, they are quality injectors, OEM honda manufactuer for injectors, so they have a proven track record for reliablity. I would go with the MSD for the price though, you cant beat that price on big *** injectors!

My question is: Which GT30 turbo are you planning to use for 500whp? SR20DET users in Japan use HKS/Garrett Japan GT3240 or GT3540 turbos for that HP level. Boost levels range from 1.3bar to 1.7 bar depending on the compression, head port, and cam profile. The GT3240 is nothing more than a T04S(60-1) BB and the GT3540 is a T04R(62-1) BB turbo. There are many trims and compressors available for both turbos.

The RC engineering calculator isn't always correct but you will need atleast 850cc injectors for that HP level. I know this because 720cc's on SR20DET's are usually running the ragged edge(85%~90%) at the 450~470hp level.

Type-ARR

I want 500whp in my turbo r because the number 500 is kewl.....

AE86

96lbs is a good size. One problem i did see was that you didn't list if you changed your fuel lines. You should get yourself -10 lines.

Oh btw, Excellent choice on turbo. The garrett gt30 is a sick turbo. You will easily make 500+hp. if everything is setup and tuned properly don't be surprised if you pull over 600.

RCSIVTEC

i personally suggest going with the 1000cc rc injectors to be on the safe side. or even run 55 to 75 cc primiary injectors and then have the 1000cc for secondarys. it all depends on what type of fuel system you prefer running. but i wont use the aem ems, go wiht the haltech ek6 or the motec m4pro. and i also suggest that you change your fuel lines as well to at least a -10 fuel feed line to have the proper volume of fuel reaching the rail.

VaporTrail

this is gonna be a street car? Perhaps I missed that somewhere....

But 500whp is a LOT. I've driven 350whp in a hatch that ran 11's...OMG you'll never use that power. But, if you've got your mind set on it...

I would really recommend using a staged injection. When you need that much fuel, using a standard set of 4 injectors is going to lead to idling problems, and serious fuel consumption issues. Using a staged injection, you can use 440cc primaries, and 550cc secondaries, and still maintain drivability with all the fuel you'd need for big hp. It's a PITA to tune, expensive to setup, but if you get it right, it works well. I would recommend a massive pump (Weldon), -10 lines and fittings (big $$$), and a GREAT tuner. It's going to be quite the task.

kidkutz

The GT30 that i have has an 0.70 A/R 56 trim compressor side ...and 0.82 A/R 84 trim turbine Side. Is there any way to attach a picture? i have a comparison pic of my old T3/T4 and my GT30 side-by-side.

You recommend -10 huh? I was going to go with -8...you guys don't think it will be enough?

We were able to support 524 whp on an SR20DE motor with MSD 72 lb/hr injectors. Factory fuel pressure (3 Bar) was set.

rtype11

the RC claculation - did you increase the uel pressure?? lets say it told you you need 1000cc at 43.5PSIG, run your pressure up say 1:1 per lbs of boost and you may only need 900cc at 63.5PSI and 20lbs of boost - just an example. If you need big injectors in Toronto I can get em cheap e-mail me.

kidkutz

you have mail

ekb18c

Well well, I didnt mean to come off like an ***, but it seems that you have done some homework with your part selection so I figured you should know what injectors to get. You even picked out the company for each part. First off I cant imagine a 500whp for the street. With a 350whp car you will be kicking some ***. Not saying that your one of these people but there are tons of people who say what they going to get but 99% of the time they dont and just bluffing. I mean you went very detailed with the parts selction so why didnt you do the injectors? Unless you just copied the part list off someone website and decided it was good for you. If however you are serious about acheiving 500whp on the prelude and have tons of money for all of this then good luck. Here is my advice get the biggest size injectors you can possilbe get so you have room to play with. You want to run on a lower duty cycle rather then running on some small injectors running on 96%. You want 500whp on a car here's what i say atleast 1000cc injectors from RC. Want to go a cheaper way, get yourself some FORD 1000cc injectors, YES I said Ford injectors.

kidkutz

ok...injectors hovering around 1000cc seems to be the general advice. and FYI...these aren't parts i'm planning to buy...i OWN 95% of them. I only lack the valve train, intercooler, and fuel injectors.

The turbo that you selected is a GT3240 or the largest member of the GT30 family.

720cc injectors can support 500whp but at 90%-100% duty cycle and at static fuel psi above 65psi.
