which injectors is everyone using?

Post by **dohctor_yaj** » Mon Mar 24, 2003 11:37 am

hey guys...a visitor from the rb forums here...

I did a search and didn't get much help other then people saying that the CA injectors drop right in to the KA24e engines and someone also said that the ford SVO/merkur brown tops should work too but someone wasn't sure if they were high or low impatence...

some guy said the fords were high...which is exactly what i'm looking for...is this true?

why i'm here is that i heard the rb20det shares the same 270cc injectors as the ka24de...i was which injectors you turbo addicts have and where did you get them from and how much?

I was looking at the Denso 440's but they look quite expensive...does RC make any 440 top feed highs?

SR20DET 370 injectors are suppose to be drop in on the KA24,I'm pretty sure RB25 injectors would be too.

I personally am getting a top-food fuel rail with 50lb. MSD injectors.

Post by **dohctor_yaj** » Mon Mar 24, 2003 11:37 am

from what meggala has told on his site, the sr20det and rb25det has side feed injectors which the ka and rb20 has the top feed injectors which is high impedence and the rb26 also has top feed but low impedence...

so what does everyone have? if ka's have side feed, then i guess i've come to the wrong place...

huh???

KA24DE have side feed injectors. the SR20DET injectors are also side feed.

You may use top feed injectors, but you will need a custom fuel rail.

Whats the confusion??

I'll be running apex-I 555cc side feed injectors, they drop in, and with a adjustable FPR, piggy back fuel computer, S23 MAF and high-flow pump It should more than handle my fuel needs(300rwhp)-chet

the 89-90 SOHC KA's have top feed injectors...

no, the RB20DET has 370 high impedance top feeds.

The RB20DET has 270cc high impedance top feeds...same as SOHC KA24E.

Post by **dohctor_yaj** » Mon Mar 24, 2003 11:37 am

thank you dennis for making things more clear...no one has really helped me still though...

alright then, for you turbo, if there is anyone with a SOHC KA, which injectors are you using, how much are they usually?

Post by **d240t2** » Mon Mar 24, 2003 11:37 am

SOHC KA+T, you can use MSD top feed injectors either a)machined to fit stock rail b) with collars and spacers to fit stock rail or c) with a custom rail. I don't know about other injector options offhand...but with those, you can get new 50lb injectors pretty cheap.

We can make a custom rail for those injectors on that motor. I like that idea better than machining injectors to fit...because if you need to replace them later (to upgrade or if something happens to one), they just swap right out.

hey dennis i got a question...if i got these injectors, can you make a custom fuel rail that would work with these injectors?

http://cgi.ebay.com/ebaymotors...33554

I'm talkin bout the 36lb injectors...they should be good for 400hp on a 6 if i'm not mistaken...

btw, how much are those MSD you're talkin about?

The three RB20DETs I have owned and the stack of tuning manuals and the FSM on my shelf say 370cc, I wouldn't mention it if I wasn't sure.

Post by **dohctor_yaj** » Mon Mar 24, 2003 11:37 am

holy shiet dude...if thats the case, then i wont need to get new injectors if my goal is only 350hp...dennis, how sure are you about the 270?

hey madscientist, what are the numbers if any of those injectors of yours...maybe i can compare to mine to make sure...would definitely appreciate it....thanks much...

what is 240kw by the way? what is the conversion from kw to hp because rb20det.com says 240 is the max from the stock injectors...

Post by **WDRacing** » Mon Mar 24, 2003 11:37 am

Guess I'm late in this subject, the RB20DET, I'm pretty sure that thr RB20DET uses 270CC topfeed high impedance injectors. The RB25DET uses side feed 370's.

Well...the RB20DET's we have messed with all had 270cc injectors. In fact, we traded them out with SOHC KA injectors once...and they are definitely the same.

I wouldn't have said it if I didn't know it to be a fact.

Well it's times like this that remind me why I don't take myself too seriously. I pulled out one of my HKS catalogs and consulted the handy dandy vehicle stat charts in the back and it say "you iss so wrong roundeye"!

RB20DE 185ccRB20DET 260cc

I hate to be wrong so it pisses me off, but at the same time I am now right again so I guess it's cool, sorry everybody, I really think I need a spanking,,,,no? anybody? Oh well I'll just pay that schoolgirl to do it again, no biggie.

At any rate one thing I am certain of is, you ain't feeding 350 horses with those. You ain't feeding them with 370s either. GT-Rs need 444s to do it and they have six. You have to do it with four so I would say 550s minimum, maybe 720s just to give yourself plenty of cushion.

better to be wrong in a forum and realise it then order the wrong injectors for something :p-chetHey dennis, how much would it run to have the I/C piping amde for my own turbo kit Im building? (you met me at the D+B meet with russ..Im chet, the guy that chipped in some money(extra) with jerome to get us the room..)

e-mail me if you like

damn...that does sound bad. I mean the party room for the meet(the buffet room). check the web page. 'doh.-chet

Post by **dohctor_yaj** » Mon Mar 24, 2003 11:37 am

well thanks alot guys...guess i can put this debate to the graves for sure now...

and i thought the rule of thumb for 6's was that the cc injectors were the peak hp you would get...

maybe it may be that its the fly hp only...looks like i'll b ordering some 550's then...

Post by **d240t2** » Mon Mar 24, 2003 11:37 am

If you need us to build intercooler piping, send us an email. I need to talk to Jason about putting together a good price range for custom i/c piping. [email protected]

Thanks,

Dennis

Post by **dohctor_yaj** » Mon Mar 24, 2003 11:37 am

hey dennis...

will i be using the stock throttle body or does your intake manifold come with one?

how would you know exactly the intercooler pipes i need if you dont know the intercooler im gonna be gettin n all?

I haven't got one yet but i was wondering then if i can buy a bunch of mandrel bend pipes from you guys and fabricate my own intercooler pipes...thanks

Post by **d240t2** » Mon Mar 24, 2003 11:37 am

1)Our intake manifold uses the stock TB.

2)Now you see why we'd offer a PRICE RANGE on custom intercooler piping...for any setup. Piping still has to be built custom, depending on the setup (engine, turbo, exhaust manifold, intake manifold, intercooler, intercooler mounting, chassis).

3)If you can fab up piping yourself, order mandrel bends from JC Whitney and go at it.

But all this is way off topic...since it sounds like you have moved over to RB talk...and this is the KA+T section. Unless you were thinking about a custom KA intake manifold...which we have talked about making...probably with a Q45 TB.

Going back to the KA24E, are they HIGH impedance? I thought someone said low impedance. I need this clarified please because I'll be looking for some 360-440cc in a while.

Post by **dohctor_yaj** » Mon Mar 24, 2003 11:37 am

yeah i know this is getting off topic...it did start on topic relating to ka injectors though...

and yes the injectors are high impedence...

Post by **noopz** » Mon Mar 24, 2003 11:37 am

hey would 370cc's from a z32 fit in a ka24e?

Post by **ImportIntelligence** » Mon Mar 24, 2003 11:37 am

Last year I was running 21 lbs of boost and still running rich on the stock injectors pushing 293 to the wheels at 98 degrees. All I run is an Apexi AFC.

Can someone please clarify sources for larger injectors for the KA24E?
