I am going to be running a Inline Pro kit, and looking into what injectors i want. I was thinking about going with 750's, high impendance(plug and play) and that way I wouldn't have to worry about a resistor box. I am also going to be running with ARP headstuds, and either a 2mm or 3mm headgasket( any opinions?), I am looking for at least 400whp, somewhere between 400-450 really. This will need to be a pretty reliable tune also, as the car will be driven quite a bit. I want to know if the 750's will be enough, or do I need to go bigger? Also, I don't know which headgasket to go with? Please give opinions!

 

I would call InlinePro and order the 3mm headgasket and ask about the injectors. If you cant tell i like InlinePro

Also i saw your sig, my roomate is asking me if your on myspecv.com His name on it is D1ZZIE. If you are you can PM him b/c he is from VA and asking what part your from. He wants to boost his SE-R

 

I have the RC 750cc injectors and inlinepro told me they are good up to 425whp.

They told me not to let the pressure go above 60 psi for the 750 cc injectors otherwise they might seize up.

That's what they told me. I would have bought larger injectors but I already had the 750 cc from my comptech set-up.

 

I called RC and they are good up to 90psi, was troubleshooting an issue I thought was related to my injectors.

 

If your fuel pressure goes past 43psi, there is a good chance the rc750's will lock up.

We've tested a few of them on the injector flow bench.

 

Darn....I may just have to get bigger injectors.

 

so what do you recommend then, ya?

and so don't bother with a 2mm headgasket?

Oh yeh I am on myspecv.com, but not to often since Im not boosted anymore and am selling the SER. same name. Im in NOVA

 

if you use the calculator in this site its about 350hp

I have 675cc injectors and put 470WHP

 

750's locking up past 43psi? I used to run 330's on my miata up to 110psi for 5 years...they didnt lock up and they were cheap ass junkyard injectors....I would say 750's are fine to 450whp easily...
