W/ my GSL-SE, i'm wondering if i should keep the fuel injection or switch to a RB dellorto or holley setup?

I'm goign to be running a street ported rebuilt 12a, new oil system, RB exhaust, and no emissions.

Also, whats up w/ DCOE or whatever it is? what does that even mean? I really have no clue.

Thanks gusy!!

Dell'orto? W/ a racing beat manifold? If the dell'orto is any good, where can i get one at?

Carbs are for old farts, build a new injection system.

ioTus

What would building a new injection system take?

Like, what components and wher eis a good place to research it?

spoolin

you should be shot for taking the 13B out and putting in a 12A. what are you thinking? if you are going to build a 12A streetport, why not tear down your 13B and build it as a four port? worked for me....and runs well with my dellorto

While many backyard mechanics favour carbs due to their simpler technology, fuel injection is more efficient and can be just as powerful if not moreso. It's a matter of learning a new skill vis a vis tuning techniques, like switching from DOS to GUI, that's all.

Spoolin, i'm street porting my 13b 6 port, i'm not sure where you got it that i was engine swapping w/ a 12a...

I'm just wondering what sgoing to give me more power and efficiency on it. I personally want to stick w/ computer driven (i really like computer devices).

Just wondering others opinions.

Here he did...

The GSL-SE ECU, and Fuel Injection is analog and archaic by today's standards. It works, but you cannot add a "chip", a "piggyback", or more injectors to it. If you go aftermarket ECU, and add more injectors - go for it.

You could also use a 2nd Gen intake with an aftermarket ECU.

The Carb idea on a ported engine is proven to work, and work well.

I like Fuel injection, but the SE one is a dinosaur, and is limited greatly by the MAF flap.

ioTus

iTrader: (5)

Well oops i meant to say 13b. my bad.

So direct are you reccomending i go carb, modernize the fuel injection, swap out w/ 2nd gen intake?

Would swapping out w/ a second gen be easy? (is it bolt on) and then is the wiring easy too?

SilverRocket

I would go carb without a second thought, but that's just me. A used Dellorto setup in nice shape will cost you $300. Plus a few bucks for a rebuild kit and a new air filter. Add a fuel pump and regulator for another $100. If you want to really take advantage of that streetport, get a shop to fab you up a Lake Cities type manifold and you're even better off. Spend a weekend or two rebuilding/cleaning the carb and installing the goodies. There you are sir, 200+ hp and you're laughing.

How are you gonna put together and tune an aftermarket FI system for that cheap? Excuse me if I'm mistaken, I don't know anything about aftermarket FI, but it just seems to me that the carb will be much more economical, not to mention much easier to install and work on. Sure you won't get quite the low end torque and fuel economy, but rotaries aren't about that anyways lol.

Mind you I am speaking from the cash-strapped student perspective, and from the eye of someone who wants to do all the work himself and doesn't have a ton of experience or fancy tools. If money is no problem, and you're just as happy to hand the car over to someone, or have the experience to take on the job yourself, by all means take the ambitious route.

I recommend an aftermarket carb for your application.

2nd Gen Intakes have larger volume, and will work with an aftermaket ECU. This was one of the options I was going to do when I first decided to go Turbo.

Originally, on my GSL-SE, I was going to use a 2nd Gen Intake, a haltech F9, and a stock 13BT Turbo and exhaust manifold for a good 275-300 hp system, using my stock GSL-SE engine.

What circumstances would change your reccomendation, for instance, would i have to be running a turbo, nos, or some other sort of mod?

Also, what type of carb do you reccomend.

Directfreak

iTrader: (2)

Exactly. Fuel Injection makes running forced induction that much better. Then it makes sense for the amount of $$ put out. Not really needed for a NOS.

Dell'orto, then Weber, Holley, they are all good. Mikuni has not been too popular with the rotaries for street applications.

ioTus

Where can i get a Dell'orto to go w/ the racing beat upper 6 port manifold?

Ebay.com / Thepartstrader.com

SilverRocket

try mazspeed.com as well, that's where I found mine

peejay

aw man, and here i was all getting excited that he was ripping out that 13B and putting a 12A in there

REVHED

If you're look at getting a carb than it might be worth waiting till Weber brings the IDA back out. The new ones should be on the market by the end of the year for about $2000 AUD so expect the price on 2nd hand ones to drop considerably.

SilverRocket

REVHED, very interesting, I did not know that.... that was my issue with the IDA when I was looking into carbs (much too expensive in comparison.)

i like EFI, and that's my goal. carbies are fun and easy to work with (despite the many times i've bitched and bitched about my Dells ) but it would be great to go out and just start my car without having to touch the gas pedal once or twice. it's also nice to have a computer making the fuel decisions for you. however, you have to look at what you've got to work with financially ... if you have the money for EFI, get it ... but if not, then there really is no decision to make, right?

ioTus

iTrader: (5)

Well, lets assume that i have an unlimited budget, and an unlimited time span.

You see, i learned this in Algebra 2, its the time variable that really matters. In two years, i will be able to afford a complete rebuild streetport, oil system, fuel system, intake, exhaust, and any other goodies i decide i want (engine purdieness and stuff).

So, assuming i have no money limit (it will just take a long frickin time...)... which will yield the most acceleration response in the end (the most honda-*** whopping. i want to be able to beat damn near every honda, except for spoons and ****).

So yeah.

What now?

iTrader: (3)

according to algebra, i should have a job, house, and about ... hmmm ... maybe 12 cars right now - so, you might wanna reconsider the algebra thing.

but seriously, you can whoop Honda-*** all day long with a carbie. it's the tuning that matters! i don't think an EFI system will net you THAT much more power over a well-tuned carburetor that you have applied to your Honda-slaughtering crusade.
to me, the advantages come with the adaptability, and the general refinement that you get. that's it. i'm just getting too frickin' old to be messing with carbies, now, that's all! (besides, i am still toying with plans for forced induction. )
look, FI systems are mechanical devices (even though they are computer-controlled). they are prone to failure at some point, just like carbies. it's just they will probably cost more to repair. my point is, reliability is not an issue, and throttle response is not an issue either. the only FI systems that have given me the same throttle response as the carbs that i've setup, are the speed-density systems (MAP) and the mechanical injection systems. all the others suck in throttle response, compared to carbs.
for a good engine management system, you're looking at at least 3G's to get started (system and throttle body(ies) and injectors, etc.) and the prices go up from there ... i got sick and stopped pricing them after i priced an 8G Motec system ... but i'm sure there are some that cost even more. directfreak's suggestion was not a bad one, because you can get the manifold/throttle assembly used and just focus on the computer parts. that may be the best for you intentions, but even he said carbs are tried and true.
my advice ... stick with a carbie! because you'd need a hell of a lot more than just an N/A 6-port to justify the trouble and expense, in my opinion.

ioTus

iTrader: (5)

Diabolical1, what carbie setup would you reccomend? I'm just about sold on a carb setup.

Also, would you reccomend i get it after or before street porting?

diabolical1

iTrader: (3)

well, i feel a bit uncomfortable recommending a carb to you, simply because i wouldn't want to sell you short.

however, i've used Holley's in the past, and i thought they were great for the street. i just found adjusting them to suit different motors (when i went to streetport) to be a pain in the ***.
now, i'm using a Dell'Orto system, and even though i like it now (i used to hate it!) i wouldn't call it the best! you can get them used, and they're easier to work on than the Holley's (at least, to me) and they give a little more power.

i've never used a Weber on my own cars before, but i've helped my friends tune them in the past, and i think they are a lot more versatile and adaptable for when you go from stockport to streetport. the thing is, i heard of one system (i think it was an LCR system) but i've never seen it, much less used it.

so try to do some research. i know revhed has experience with Webers, so you could ask him, i guess. i think if you can find a Weber for a 6-port, you should probably get that.

hope this helps.
