sr20det to ca18det injectors, will they fit

[pulsar gtr]

will the sr20det injectors fit with out any mods on the ca18det. if not, Where can I buy 550cc injectors for the ca18det, preferably from the US or Canada, since I live in Canada. Also I am running 16psi on my stock ca18det engine with JWT ecu and MAF, if I need to increase the hp, what is the max hp that I can get out of this engine with out any internal mods or risk of doing serious damage to it. I dyno my car at 250hp at the fly wheel and 207hp at the wheels. I have 1987 nissan pulsar front wheel drive.

Thank you for your time.

the SR20 stock injectors are 370cc, same as the CA18. The SR20 uses side feed, the CA18 uses the much easier to find top feed. If you only want 550cc go get the injectors out of a second gen RX-7, they drop right in and they're 550ccs. Easy and cheap, they can be rebuilt for 10 bucks a piece. : )

n/a rx7's, or do they have to be turbo?

[Daunttless]

hmm, I know the Turbo's have them. I'm pretty sure it has to be a Turbo II.

Thanks every one for your great help, I still have one more question, what is the exact year that the RX-7 came with the 550 injectors.

Thank you,

87-92 Turbo IIs will have the 550CCs.

440s from the Pulsar GTiR and Skyline GTR also fit straight in...

[Daunttless]

hehe, its a little harder to find those in the junkyard though. : )

What about the 93+ RX-7 Turbos? Are they top-feed as well? If so, how many cc's do they flow?

[Nismo_Freak]

550cc but they have a different OHM rating... I *believe* the 3rd Gen. (93+) have the low impedence and the Turbo IIs have the high impedence. So basically both will work but the 3rd Gens should be a tiny bit higher flowing.

What about MkIII 87-92 Toyota Supra injectors? I read somewhere they could drop right in (ca18det). They are 440 cc injectors, but the 87-88 are different impedence than the 89-92's.

[Nismo_Freak]

Perhaps... I would just get the 550s if your gonna spend the money.

[controler]

/me smiles . I use to own a MkIII supra, and I've got at least 3 sets of injectors laying around. That is 18 total. *I think*. Well how do the 440's and a t28 sound with a target of 1 bar boost, that is considering I get the ecu modified.

[JDM_1990_S13]

are you looking to part with any of your 18 440's as you have soooooo many?? what are they low or high impedence, i think the CAuses Low impedence right?? and will it plug in or is some wireing needed???
