650's or 680's?

[Knuckles2.0]

so its bigger injector time, i'm going with either fic 650's or extremepsi's 680's.... ups and down to either... i'm not sure what turbo to go with yet either a evo16g or a pte50.. so info please

Best bet is to go with the denso 720's

I run a AGP 50 trim and found my injector DC was pretty high. Better to be low then close to 85%.

If you go with a 16G then 650's will be fine but if you with a 50 trim then 720's will be better.

 

[ECLIPSE4x4]

The reason I just said 720's is becasue I used to have a 16G and I bought small injectors and had to upgrade later.

Sometimes it better to buy once

I had 660 ball/disc on my L2R and 50-trim and they were fine for 20psi.

650's for a 16g? christ. anyone remember 5 years ago when 550's were rediclous for a 20g?

650's for a 16g, wow.

 

[L2RTSiAWD]

I don't think 550's were ever rediculous for a 20g

 

[ECLIPSE4x4]

I don't think they are either. I am simply stating keep yourself available for upgrades. Keep a buffer so you do not have to buy again.

What makes their brand injector different than an FIC injector anyway? The pictures on thier website shoing thier own injector are all from FIC's website anyways so what gives?

Dont get injectors from extremepsi. I have them and they turned out ok in the end. But my first order, one of them did not fit, and so I had to send all 4 back and wait 2 weeks for a new set. Get some injectors from a different place. Extreme PSI is cheap, but you get what you pay for.

Word on buying bigger injectors... I just got Denso 660cc and they turned out to flow 690cc @ 43psi... I only have a 16G but am going to a SS44 next summer. Buy Injectors once..

 

[laza101]

Go with 650cc minimum. I have FIC 650's and am happy with them. 550's are NOT worth it from my experience.

 

[ECLIPSE4x4]

Rubican brought up a very good point.

What do the extreme psi injectors flow at 43 PSI.

I've heard that the PTE injectors (680cc, I belive) flow alot less at DSM base FP to the tune of around 625cc - 640cc for 1G and 2G..

You think that's bad, for a little while I had 780's on my Big 16G , but I knew I was going to a bigger turbo. However, I am now considering 660s or 720s.

 

[AL92]

I have FIC 650 and they fit good and eliminate the factory hard seals.

Also 650 flow more or any injector as you raise fuel pressure so all a person might need is an afpr and good pump and 650s rather than 720s with no afpr.Just a thought guys.

 

[ECLIPSE4x4]

WHY would you want 720's without and FPR????

 

[dsmturboawd]

fpr doesnt have anything to do with the injector size, rather the pump size.
