im thinking about getting a JRSC on my prelude in the next 6-8 months but i need injectors now, im running my old injectors which are severely underrated, not even stock size. which for a prelude is 290-330cc. im thinking about getting RC 370's or 400's and i need to know which size would be adequate for a JRSC they are both the same price, but i also want it to run decent NA for the time being. i also have a hondata stage 2 ECU which i will have tuned in a month or so.

 

I believe the most common combo with Hondata are 440's........which will support the JRSC just fine.

 

If you've purchased a Hondata and wish to make use of the JRSC base map, go with 550's. 550's also let you keep the stock regulator (and thus fuel pressures), while you may need to purchase an adjustable FPR to tweak fuel pressures with 440's. Try looking through the posts on the F/I forum on http://www.preludeonline.com for more info.

I don't know how much you can get 440's for, but you can get 550's for 270 here:

It takes a few weeks (just over 3 for me) for the injectors to arrive, though, so keep that in mind.

 

thats a great price but i think 550's are way too big for my setup, remember i am going to be NA for about 8 months and those are almost 2X the stock size. im looking more in the 370-400 range, how would my car idle with something that large?
