what injector do would suit my purpose?

[sharky]

Im thinking of upgrading my fuel system when i have my ecu installed. But im stumped as to what size to get. I know of a type R who has RC 310cc saturated injectors but what would i need on a B18B2?And could someone explain the difference b/w saturated and peak and hold injectors.

Basically i have a MoTec M4 and Spoon cam sprockets and an AEM lightweight pully kit ready to go on. The rest of the plan is a Skunk2 intake manifold, fuel pump and injectors.

What do i need? And costs would be good too.

Sorry to go a WAY BIT OFF TOPIC, but is that a shark about to eat a guy out of a helicopter??? :confused:

[sharky]

dammit tracer, i thought someone had an answer! ;) ha ha

Yeah its photoshop'd but i saw it in a magazine ages ago and just found it on the net the bigger version is awesome

[ProECU]

use what you have, what makes you think you need larger injectors for a SK2 intake manifold & lightened flywheel?

[BLKCRX]

Stock Injectors will be fine... but if you must... go 310RC but honestly its not needed...

Cool, then ill go with that ProECU, cheers, but just to give you an idea

Full xforce exhaust system (done)
pod filter (done)
lightweight chrome fly (done)
etreme HD ceramic cushion button clutch (done)
MoTec M4 (purchased)
SK2 intake manifold
Spoon Cam Sprockets (purchased)
AEM pully kit
Install and Tune

This is what im wantin to do/done, if i dont stand to gain anything anymore power with an upgraded fuel system than what i will get with this set up then that saves me a good $1000+ (i found hondatech).

And turbo is out of the question (I looked into it a lot and its a no go) to those out there wanting to type "boost it" ;)

the easy and most effective way to increase fuel flow (a little bit) is to increase fuel pressure, ie with an adjustable fuel pressure regulator, like the B&M one ($130)

this will 'virtually' increase the fuel injector flow rate :)

see here for example & theory:

http://www.rceng.com/technical.htm

only on a dyno when examining your A/F ratios will you see if you need to increase fuel pressure due to air-flow increases (of which you have minimal)...

[strepto]

The stock injectors are 240cc and will be more then enough for a nice A/F curve up to about 200whp. The OEM fuelpump can supply injectors up to 370CC without problems, but you'd wanna get a FPR w. gauge to make sure your going right. I cant stress enough the importance of a A/F curve - to go with proper A/F tuning. That being said - you're mods arent really performance mods as such, so I see no need for a change in your current fuelsetup.

[weezer]

my stock Injectors and fuel reg was good for about 124kw. You will be fine with the stock injectors for the mods you got. If anything just change the FPR like what tink said

[sharky]

Thanks guys for your responces, this is acctually a huge relief!

[ProECU]

To make power you will need to lean the tune hence reduce injector duty cycle.

Since your intake charge flow has not changed, you wont need any upgrades to fuel pressure, fuel pump, or injectors.

Perhaps you can email me or just tap me on the shoulder next cruise/meet or even before then if you need to talk options.

Cheers

thanks mate ill do that

motec, wow, great exhaust.. did u get 2 of the big bottles also?

[sharky]

sorry Weq correct me if im wrong but are you taking the p*ss?

Can never really tell on here?

AHah u got me ;)

Im just wondering, why fork out so much cash on a motec ecu when you really havent dont any engine modifications yet. atleast grab a set of stage 1 cams please!

[strepto]

Funny you should mention that, because my grill topped out at 160 degrees. I need two bags of coal.. the big ones..

[sharky]

Oh trust me i know what your saying. Do you know any companies that make them for the B18B2 engine? I admit that as for cams i havent researched deeply but want ive been finding is that unless the car is vtec, cams dont exist.

As for reasons for the motec, why not go for the best? I mean i can afford it. Yes i could save a heap and go with hondata or even a shitty emanage but personally i dont believe in going cheap when it comes to cars, especially when anything to do with the engine management and internals is involved.

Im no expert on cars actually im a car noob but i have seen mates go cheap with their cars and they end up running like shit and they where very unhappy in the end for the $ spent.

[sharky]

you just have to look at some other threads on here to see the drama's ppl are having when they do things on the cheap, i recall a turbo install....:)

[strepto]

Uhm.. If this is a B18B engine with some light boltons, you dont need anykind of tuning at all really.. The only thing you need, is a VTEC head and do a ls/vtec :) Then we'll talk tuning :)

[sharky]

ha ha that is more trouble than its worth ive heard. I just put a stop on my order for the MoTec i only placed it a couple of days ago, the shop hadnt even put the order through thank god. I have to say weq is right, i just email proECU about hondata we'll see what he says. What a head f*k.

[tinkerbell]

no offence sharky, as you seem to be open to suggestions,

i do not think that you will even see very many HP from your listed mods :(

if you "can afford a motec" at least get a decent set of headers...

and IMO, anyone who says a frankenstein conversion is "more trouble than it is worth" either has never tried it, or ****ed it up...

[Weq]

LS/Vtec is a great mod. more power then u would expect, if u want to stay NA :) Golden eagle do install kits which make things easy...

IMO though, if u got cash for a motec, get a turbo kit/custom. b18b turbo puts out good HP, stock. :P

<------------ has been waiting for PRO-ECU to come out for some time :rolleyes:

I hear we don't have to wait to much longer :p

[strepto]

There is no point in changing ECU or get ECU stuff if you dont have anything on your car worth tuning more then the stock ECU already does for you in closed loop. Put your money to some real use! :)

NO!!! not true IMO

There;s allways grains to be had here :p tho they my not be much till ya do some real work :thumbsup:

So if your sure your going to mod a lot then why put it off coze ya got'a do it a some point

[tinkerbell]

tho they my not be much till ya do some real work

well, why bother mentioning it???

[Lukezen27]

well, why bother mentioning it???

So you could leave it till the very end then?

[tinkerbell]

i would wait untill the dyno showed that you needed one.

ie A/F ratio is too far out of optimal range...

[Lukezen27]

pls check your post for gramatical/syntax errors
OK then

[tinkerbell]

*sigh*

sorry dude :thumbsup:

[tinkerbell]

Why on earth would you bother mentioning it but to piss me off?

Bored?

i dont answer questions that have two meanings.

My point was that he doesn't need the ECU stuff yet. Yes, if he continues to modify his engine he might need it later on, but I dont understand why he needs something expensive, when the S200 or even the Uberdata will do the job just fine. All you need for a N/A car is the basic S200 kit from Hondata, and a wideband (I prefer PLX because you can rewire it to give out 1V narrowband o2 feedback to the stock ECU).

Good call :thumbsup:

[sharky]

Weq mentioned a cam upgrade. I did some research and talked to a few ppl and they sent me to the crower website. They make stage 1 cam's for the B18B. So eventually i will be placing an order for a set, i dont know if anyone on here deals with crower but i might just order them online.

[Weq]

sharky: dude, step back. dont go buying parts randomly. IMO u seem like u wanna work ur B18B. Go onto honda-tech and search "LS" "LS/VTEC" "LS integra" or "b18b" and u will find a route. RESEARCH then BUY. give urself a good 1-3months of research before u make ur first purcahse!

<----------- has been reading for over 6 months and I'm still not happy I know the right way to start :p

Lots'a $$$$$$ if you start out the wrong way :rolleyes:
