Hello all, I was wondering if the 280cc/min prelude fuel injectors could handle 200 whp? That is what I am shooting for after I get my obd1 ecu and tune it with a fields sfc. My set up is: cai,jdm 4-1,greddy evo,itr pistons,toda b,cam gears,fpr,carsound cat,and skunk im. This is in a 00 gsr.

240's can handle 200whp......... so the 280's will work fine

 

I thought the 240's could only handle 180-190 whp?

 

So did I, I'd imagine the prelude injectors could handle 200whp, but why not just dish out the extra money and get some RC 310's or 370's if your goin hondata

 

I was considering getting a set of lude injectors... That's if you can gettem cheap, but I would rather spend another 50 to 60 bucks for brand new RC 310cc injectors, est. $340 clips included.

 

Prelude injectors ('97+) are 290cc/min and $150 a set readily available..... and they plug right in where the old 240 (itr) injectors did...

 

yea but will 290's handle a good 210whp w/ a 255lph pump?

 

But are those new or used? If I am correct those are used injectors?

 

Does used injectors last... do they deteriate? Is it safe to buy used injectors?

 

.....try it. At worst, you can sell the lude injectors without taking much of a loss (if any).

azn, sure they're used - but they're meant to be used...

 

I would hope it can handle 200whps, because that what I will be using this summer and I am hoping for 190-200whps!!

 

ditto.

They're ~21% bigger than stock itr injectors.....

I could be wrong, but seemingly that would mean that they'd be good for at least 193.6whp on stock fuel pressures and duty cycle.....

 

To make 207whp on stock injectors, i needed about 80psi or so of pressure.
And the pump wasnt able to keep up very well. 290cc would be able to
take care of 200-210whp i would think. It really depends on your ECU program.

 

 

ok, I am pretty clear on the lude injectors, they look like they will do the trick. Do you guys think my stock gsr fuel pump will suffice? I don't imagine I will be cranking the fp more than 60 psi.....who knows?

 

SO long as you dont go past 60psi you will be ok, assuming the pump is in
decent shape.

 

How is the idle with prelude injectors on a B series motor? Will a SAFC be needed. Also, is a 12:1 fmu to much with those injectors or will a 10:1 be adequate. TIA

 

are the lude injectors the same for auto and manuel cars? how about vtec and non vtec? just want ot make sure i get the the right ones.
