I came across a set of 1600cc injectors that supposedly drop right into the stock fuel rail. theyre said to be manufactured by Venom and do not require resistors.

Is there such a thing??? Would the stock fuel rail flow enough???

I've always seen the bosch's floating around but those do require the use of an aftermarket rail and resistors.

Now, as far as I know, the venoms are not side feed (FD drop-in) injectors. I may be wrong though.

No. In fact, the 850cc stock secondary injectors are the biggest side-feed injectors available.

There is almost no reason to go 1600s IMO (other than potential reliability issues with overbored injectors), you can always run 850/1300 if you need more fuel. Anyone NEEDING more fuel than can be provided by 850/1300 combination is typically not worried about the hassles involved with the 1600s install...

I specificaly remember reading a huge thread on side feed 1600s. That would essentialy drop right in. And they werent bored out ones. I cant remember what came of them. I think the last I read someone was gonna buy a pair and flow test them.

I personaly would NOT put 1300s in my car. I've heard too many horror stories of them getting stuck and just half a year ago I got to help drop a fellow 7 owners new engine in because he popped his old one when one of his 1300s got stuck closed.


I'll go search for that thread

there ya go

And there's dozens of guys who have ran 1300cc injectors for years without a single issue too. It's common knowledge that RC uses a varnish than tends to make the injector stick if it's been sitting around too long. That goes for even non-bored out injectors. My engine rebuilder says he hasn't experienced any problems with them and that's good enough for me.

Going with 1600cc injectors means complete removal of smog equipment (along with having to replumb the fuel system), and to many of us, that's not acceptable. You pretty much have to be no-emissions plus non-seq or single turbo to install 1600cc injectors.

They are also harder to stage correctly than 1300cc secondaries.

Like any modification, 1600cc injectors have pros AND cons. Not pointing out the cons of something you are recommending is not helpful -- just like all the idiots here who just spout off "go single" or "go LS-1" to someone having a seq or rotary issue.

Did you actually read that thread? It was a bust! The injectors were proven to be ****!

Gamezilla

I did not read it. As I stated in my previous post all I remembered was reading a thread where someone found them and last I heard they were going to flow test them. I personally would rather not buy venom injectors, but all the thread starter asked was if there was such a thing. There is.

rynberg

No, there isn't. Not functional ones anyway. If you know nothing about a product/mod you are pointing someone towards, it always pays to post a disclaimer....

Well, i have 550/1200 which i was thinking of switching to 1200/1600 with just a primary rail to accomodate secondaries. I'll probably do that and not worry about any issues. Oh btw, the 850/1300 combo seems to be marginal for say a GT35/40 or at least limiting if using C16 and high boost.

Gamezilla

Pointing someone towards? Please refer me to any part in my pervious posts where I said he SHOULD get these? I can see where I typed I would never buy anything from Venom. Thats about it. How bout you pull your head out of your *** and start acting in a civil manner instead of acting like an arrogant *******.

Now, what venom markets them as and what they actually do are two different things. Does venom sell 1600cc injectors? Yes, at least they claim they do. Do they really flow 1600ccs? No. That information can be found in the thread I provided. He asked a simple question and I refered him to a very long post that covered ALL the information he would need to make an educated decision. All you came in here doing was blankly stating no (which will probably confuse him since he obviously has heard somewhere of side feed 1600s) and then state your opinion. Great contribution.

Gamezilla

I dont see any reason to upgrade the primaries that much. 850s should be enough. Remember, you upgrade the primaries that big and youre gonna get HORRIBLE gas mileage. My friend has a T78 with 550/1600s and he has no issues. The 1600s flow so much it more than compensates for the stock primaries. This all is relative to what kind of turbo and how much boost you plan on running too. I guess if you were planning on running like 20+ psi then those 1200s might come in handy.

rynberg

Hmm...I don't see anything the least bit offensive in any of the posts in this thread, unless you are referring to the laughing smilie I used. The smilie was to emphasize the point that the Venoms were a **** product.

I haven't stated any erroneous information in this thread, so I don't know why I would have to pull my head out of my ***.

Again, I don't see where I've been an arrogant ******* at all.

The only thing I didn't do was summarize the findings of the thread you posted in my initial post. Neither did you. So get the chip off your shoulder.

damn, another hour and a half wasted reading through that thread...at the end of 10 pages, these 1600cc injectors flow 550cc instead. This is accordint to a few people who bought them and had them flow tested by RC engineering and other shops.

Dissapointing to say the least! But better to find out by reading than by acutal purchase and a blown motor.

thanx for the searching out the thread!
