so what impedence are we talking about for legends? 12ohm? 16ohm?
i don't know how to classify these things and i didn't read up on them thinking an fmu would be enough for now.

i think i'll give venom a call when i can, see if i cant get some "special" ones made up for a decent price later . i know they have the right ones for c30a1 so it can't be that hard to do.

yeah venom can do them and rc engineering. good luck

2ohm if you want to remain on the stock side of things.

Those 330's are plenty for what you need currently and they are plug n play for 300 or less. You plan on running 400cc+ your going to have to go standalone or you will be hard pressed fighting timing issues. You'll probably pop headgaskets before crossing the 300WHP mark. I cant even imagine the spikes you see on the dyno....
Its a known fact that the EMS utilizes injectors and theyre sizes much better than a piggy back or nothing at all. So you can use smaller and still get the output.

330cc? that would be good for up to 5.5 psi
(1-(240/330))*100% equals apexi correction factor of -28%
((330/240)*14.7psi)-14.7=5.5 psi boost

good for the mean time because a friend of mine is installing a turbo on his 98 prelude so all i would have to find would be two (92-01 used the same h22/h23 so i'm assuming it's the same) but i need to be able to support at least 10psi in the long run (final goal, thankfully the c32a has a compression ratio of 9:1 making this possible when i finnaly install my intercooler) so if our original flow is 240cc i need 400cc for 10 psi

its acualy 9.6:1

is there any difference between the h22a and the h22a4 engine in terms of fuel injectors?

Has to be the 92-96 Vtec prelude, I dont know what engine code that is.

 

[alienclay]

the 92-96 prelude vetec used the h22a the 97-01 prelude used the h22a4. no known changes in powerplant as far as i can find, probably only minor changes for emmisions sensors or something, but the reason i ask is that the used injectors i'm trying to get from a friend is off an h22a4.

http://en.wikipedia.org/wiki/Honda_H_engine

he bought a set of rc injectors a couple of days ago and now he's trying to figure out how to install high impedence injectors. (if anybody knows how to work that i'll pass it on) i think i'll try to find some remanufactured ones on ebay or something. 3.5 psi is irritating. i feel like i would just edge out my 94GS at 60ft, (but take it down the line for sure. highway driving is a whole new world now). but i need to get this fuel thing figured out.

 

[alienclay]

skip that, i just found out that there is a differance. the injectores on 97-01 aer high impedance, and the injectors on 92-96 are low,... looks like i gotta get a full set.

Trust me, fuel mileage goes to shit on the 330's even tuned-it should be plenty.

ok, now i'm getting some conflicting info.
i just called venom performance and asked them on the stock fuel flow rates for the 91nsx (c30a1) legend (c32a6) and prelude (h22a4) and after a little playing around computer hopping the tech told me that honda used the same fuel injector in all three with a stock flow rate of 260cc/min (that made more sense to me, 240 was just a weeeeeee bit low for the 290 hp the nsx was putting out that year, unless they had some amazing bsfc. that and while on ebay i was finding aftermarket rc injectors for preludes at 310cc/min. why go lower.) the only reason the stock numbers were different on the venom website was for stock and manufacturar cataloging. something about the 006 being for acuras while the other was for honda or some crap. (but with a 200hp engine is that hitting the wall of injector saturation on the h22 and c30a? )
they also told me that all these injectors were 12ohm.

anyway, i'm giving up on all the bs and i'm going to buy remanufactured vetec prelude injectors on ebay today. something tells me dv8 knows what he's talking about here, along with a fuel pump and a fuel pressure guage i can see from the cockpit from jegs. maybe i can finnaly get this over with and get some numbers.

and yes, i do plan on being done before april22

The NA1 NSX uses 2 ohm 240cc, from what ive seen are the same as the legend, also 2 ohm. Then theres the 270cc for the later year NSX's (NA2).
Comptech used to sell injectors for their NSX blower kits that were 335cc at stock blower boost. Those 335cc injectors are VTEC prelude 330cc injectors treated to an RC clean,blueprint and calibration.
Bottom line Vtec 'ludes have 330cc 2 ohm factory injectors. They are in my car right now means that they are plug and play as long as you have the ability to tune them.
The Legend injectors will work for any NA setup and a good amount of nitrous too.Anyone thats going to a bigger injector in a Legend better be going for a big shot of nitrous or F/I.
Another beauty of the EMS is that you can have 1600cc injectors and can still be tuned to flow only what you need.

Hope your turbo's done before mine.......

if i can't claim best at least i can claim first :-D

looks like that body kit and paint job i was planning for next year may be replaced by said aem setup. but i still wan't to claim the victory of being able to make this DIY work for the peeps (like my self) who may not feel the nesessity of buying a 2k$ ems. if i had known what i know now about this stuff 2-4 years ago, i wouldn't have wasted so much money in the mean time on nitrous and other stuff.(seattle low temp, long wait times for the bottle to warm up,...) i already ordered 8 of these prelude FIs, and if i still get four from a friend i'll have an extra set of six for the next one who wants to try and if this works than i will meet my goal of doing this for under 3k. (it seems like evey year or two some con artist or jackass wants to talk about doing a 10 man group buy on a supercharger or something like it for 3k. i'm tired of talk)
whatever,.. i'll check back with you guys when they come in and i have a chance to try it out. thanks dv8

Does that mean you've started already??????

What about DSM injectors? The 450cc

clay,

if you meant "first" as done before DV8 then probably...but you are not the first with a running turbo legend. Rear mount turbo yes.

just clearing things up

 

[alienclay]

oh i recognise this. i found pics online of one built in colorado with a t3/43 hybrid under the hood where the sirbox is at, but the exhaust work nessasary was far more than i found to be acceptable.

but as far as i know, or can find info on. my car is the second gen2 turbo legend. if there are others send up a link, i'm very interested and would like to get in contact with others who already have to get some info.

 

[hotlavaflow]

Actually your 3rd on this forum and there are rumers of two others that havent surfaced. There's sr79labrat's single and a twin turbo w/ full skyline conversion.

 

[tw1st]

Wasnt it found the the turbos on that werent functional? or that it didnt run? Something along those lines...

i have numorous pics and talk from houston street racers etc and i have only seen it park or trailered. Never seen it running or heard it running yet.

 

[Johnny Kim]

if ure talking bout the full blown drag twin turbo legend(gary?? not sure) the shop was closed b4 he could finish it.
