hello,

can some one clarify the differences between the two.... is it injector size?

253001 (JECS)
253002 (DENSO)

Thats looking on Nengun

Adam Kindness · 11th May 2007, 12:05 AM

so..... which rail would i need for Sard 800cc injectors

ANDY H · 11th May 2007, 12:13 AM

jecs is standard 10.5mm
denso is 11mm
sard 800's will be 11mm, my 700's are 11mm

Adam Kindness · 11th May 2007, 12:22 AM

cheers

I made a mistake there... I'll be going for the SARD 700's... the 800's are a bit too much for my setup.

Next Q:

D Jetro or normal PFC with Nismo AFMs

The D Jetro option will be quite a bit cheaper. Is there any significant down sides to using MAP sensors over AFM's?

donk_316 · 11th May 2007, 12:59 AM

Yeah but the 800's are twin spray!

Adam Kindness · 11th May 2007, 01:22 AM

whats the benifit of that? They are also slower.... 1.2 rather than 0.8 for 700's

Sards are Densos, I've got Sard 700cc that went right into the Denso-sized rail. I do wish I'd have gone bigger, perhaps 1000cc. With big injectors you just end up running them at less duty cycle. I've hit up to 90% duty with my 700cc.

Adam Kindness · 11th May 2007, 01:58 AM

yes.... may well go for 800's then...

I'd think idle would be a bit 'rich' with 1000's

donk_316 · 11th May 2007, 06:30 AM

dual spray is a design some injectors have where it shoots out through two holes in the injector spraying fuel directly behind the intake valve instead of one big gush.

and the 800s are 1.1ms lag

Adam Kindness · 11th May 2007, 05:51 PM

so.... is the two jet spray pattern pref to a single jet?

donk_316 · 11th May 2007, 06:24 PM
