Any suggestions...this is my set up: LS block/GSR head/ITR internals/CTR cams/balanced crank/PP head/skunk2 intake/70mm TB...

 

what exactly are you asking???

 

I want to upgrade to bigger injectors...how many cc's is advisable? And are they expensive and worth the money?

 

pretty sure a stock ecu will not idle anything bigger than 310's

 

Well DSM 450 are available from a GSX or I'm pretty sure DSM 350's are on the N/A eclipse/talons. Either way you may need a AFC. You can get 92-95 Prelude injectors which are around 240's. Heres a few suggestions. Dunno how well those work on a stock ECU.

 

i think preludes are 275cc, and all other honda 4cyl's are 235cc

 

for the reply...I'll try to research further.

 

I might have been wrong its 240 for others and 280 are prelude V-tec sorry about that, bad day at the job

 

lol...i think everyone understands

 

You could use the lude ones, but I am using obd1 GSR injectors on my built crvtec and they seem to be fine. I mean would your motor require any more fuel than an ITR motor?

 

but isn't GS-R injectors high impediance?? You can use them but remove injector resistor box. There still 240's pretty sure though and OBD0 are all low impediance injectors, he want plug and play correct?? No rewires

this should help you out

 

Yes, I was just saying that I am using stock GSR injectors (240cc)...thats all.

 

I was going to switch mine to Type R plugs...but didnt realize they're the same flow rate as my current ones (91 teg)...What does peak and hold mean as suppose to saturated?

 

Yeah sorry bout the disappointment on the flow rates. Peak holds and saturated always get me skrewed up. I'm not positive what it means or does but I know it must have something to do with the OHMs loads meaning you have to run the injectors with a injector resistor box or with out. PLEASE correct me if wrong I really would like to know the difference.
