Update on injectors - Page 2 - ZR-1 Net Registry Forums

tomtom72 · 01-03-2006

haber, I bought the 205's. You can use the 225's. Z Factor explained it in my thread about the miss in my motor. Either one is okay as RC rates the flow at less PSI than GM. Six of one 1/2 doz of the other. If you plan on some major porting work & exhaust swap out w/ headers & gears & chip then the 225's might be better as there might be more for a tuner to work with.

The price I got was $64.00 each if I bought all 16 but I snuck in just before a price increase I was told. That was back in late Sept 05. I think the $68 sounds fair if you price them against the OE stuff from GM. I am satisfied but my stuff was shorting and leaking I found out after I pulled them out for a look see. I am very happy with my RC 205's as the car runs very well, to me anyway. I think that the injectors were also leaking as the secondary butterflys also had some gum on the top sides of the butterflys?? It just pulls smoother and feels more uniform after 3.5 K rpms.

Tom I have headers, a Corsa exhaust and I am working with Aaron from South Georgia Corvettes on a new chip. My car was running very rich so I decided to change the chip and lean it out, for all I know I have some leaking injectors also, but I had 1 fail on the passenger side bank, this is when I decided to replace them all, I think the 225's will be a little big unless Aaron tell me to get them and he will program the chip to accomadate. I was just interested to get some feed back from some one who actuall has the 205's in their car. I have no intentions of racing or any of that stuff, I just want the car to perform at it's best the way that it is.

I wish I knew enough to give more than a "butt dyno" answer. The 205's work fine by me but I don't know anything. Heck I didn't even realize that some of my 2* injectors were leaking alittle!

If I were you I would go with what SGC says to use. They know their Z's & I would respect their opinion. I can only say that I am very pleased with the product. The car runs very strong to me but I've nothing to compare it to. I can only say I feel that I got more than my $'s worth from the RC injectors.

Good luck!

Tom

Tom thanks again, basically that is what I am after, just making the car run the way is suppose to run, I have had my car for 10 years and I have been very happy with it.

Good morning blackjack nice to hear from you and thanks for the update, I imagine when I get my injectors out I will find the same thing that you did. What size did you use when replacing the original injectors and did you replace both sets.

Hey that's wild I never thought about replacing the vaccum lines and "o" rings, can you still buy these from the dealer or do I have to scrounge around to find them. I have the Corsa exhaust, headers, and I was in the process of dynoing the car for a new prom when a couple of the injectors failed. I am working with Aaron at SGC on the prom it was running really rich when I started so when the injectors are in we will finally get it finished. Up here in Canada I really (or I haven't heard) of a shop that really understands these cars, so I am being really careful and asking a lot of questions. I have a shop that is very good with race cars and the retro cars and if I can tell them what I need done they are quite capable of doing the job, they just can't tell me what combination works or what is good and what is not. After I get the car sorted out I will be doing the 4:10 gear swap and it should be a real treat to drive, I can hardly wait.

Hey you are very fortunate to have that guy, I think that I am not going to have any choice, if I want my car set up right I am going to have to take it to the States and have someone who really knows what they are doing get their hand on it. Don't misunderstand what I am saying, the car runs good but I think that it could run a lot better with fine tuning. I'll keep you posted when I get the injectors in and get it dynoed and the engine leaned out to where it is suppose to be. When I first had it on the dyno it produced 347 RWHP with just the exhaust change and headers, I couldn't tell you if that is good or not, I haven't had a chance to do another pull due to the injector problem. They told me from what they saw on the dyno sheet that the engine was running really rich, so enter the new chip to lean it out but I haven't been able to make the final pull, we'll see what happens. Due to the lack of service availability up here I am seriously considering selling the car and buying something a little more user friendly.
