Carborated vs Fuel injected.

[kornball426]

FAST and others mostly can use open or closed loop, map sensors, air flow density, mass air flow, throttle position sensors, wide or narrow band O2, all kinds of sh*t... It's not going to be as easy as just plugging it in and driving away like putting an OEM ecu in a car but they will do anything you want them to do. And it will definitely pass a tail pipe emissions test on a G-body and I think because of such an upgrade it would eliminate the visual portion of emissions inspection.

And most of them come in two versions the cheaper one usually comes with MAP sensors that read up to 1 bar (15psi for people who don't know), and the more expensive ones will work up to 3 bar (45 psi).

Hilborn and Kinsler injection make these super sexy EFI conversions using the FAST efi systems I want one so bad.

FAST doesn't have electronic power mang for transmission, fuel pressure detection, injector pulse width compensation, ind. cylinder fuel adjustments, self tuning fuel trims, ability to upgrade to two knock sensors, has less %VE multiplying tables etc. Its a good priced intermediate system and IMO would be easier to tune, EFI technology and electromotive-(to a lesser extent) are a bit more like you'd find in an upgraded ls1 pcm. None of them beat motec.

I haven't priced a motec since about I dunno 2001-2002 ish when I wanted to turbo my Neon R/T (420A DOHC) and realized it's way too expensive to go as fast as I wanted to go and should just get a Talon TSI like my brother. And then I realized so called "tuner" cars are stupid and American muscle is where it's at. But at the time a motec was several thousand dollars for nothing but the ECU. I'm not saying they're equal but my original point was EFI is superior than carburetion... Can a carburetor do any of the things you just said? Definitely not.

The FAST efi and most of the other systems in its class do everything you need it to do unless you're building a completely over the top race engine that's pushing boost limits to the point that a momentary lean out or boost surge will burn a hole through a piston.

true true, motec is over the top. I'm not disagreeing with you that carbs would be better 🙂 . If the OP is looking for ls1 style (which I don't think she really is) efi technology is where I'd look. Whats your bro done with the talon?

He had a 92 TSI with a 4G64 crank and bored it out to about 2.2L from the stock 2.0, ported 1G head, a "big" 16G turbo with a ported housing and cut turbine, a eBay special intercooler with home made plumbing, he had it boosted to around 20psi, bored throttle body, extrude honed intake, bigger injectors. All the mods basically you can do before getting into huge money. This was back in the day though when imports first became hot so it had a stock ECU with a piggy back from HKS, AEM, or Greddy I can't remember, for a better fuel curve or whatever. I was never huge into the imports, I always wanted a 1st (scratch that, 2nd gen the ones that look like 80's Corolla's but super bad *ss batmobile looking) gen Supra with a 7MGTE (well actually I wanted a 2JZGTTE) but couldn't afford it so I gave up on imports and went to American muscle like I said. :lol:

I will tell you though that car was crazy fast he blew it up though and was going to rebuild it with better parts but then he had a kid and that was then end of that.

good stuff I think a lot of guys on here would be surprised how quick those cars are :lol: , theres a guy around here with and awd one whose done about the same, kept the 2L stock though (with piggy back and a bigger turbo, not sure what size). I've been back and forth on buying a tsi fwd for the mileage. Its sad that cars have to go when kids come. But I'm now into a little roadster like a tbucket or something light and extremely simple that gets good mileage compared to my guzzlers. its probably a good thing the funds aren't there for me to buy nice sh*t

the fedex guy stops by from time to time he's always talking about his 7mgt, its a pretty car. He's envious of the g bodies of course 🙂 hopefully we don't get flamed for rice-posting

Let`s not forget one big advantage of efi over carbs. We Pretty much all agree that all else being equal, you will get better millage with efi. This also means less unburned fuel to wash down the cylinder walls, thus leading to longer engine life. Something we can all appreciate.

Current problem aside, there is no comparison for a modern engine, efi, period. The tuning is simple, the funtion is way better and now if you're starting from scratch and willing to do a little work, it's as cheap or cheaper. I speak as a guy that has done several swaps of late model powertrains into early cars. I'm an old dude, but I ain't stuck in the past, EFI baby!

That's the opinon's I was looking for. 🙂 I like the keeping the turbo in the garage idea. I've went through all the steps I'd need to make to turn it FI. It's a lot of work but a lot I can do by myself and save on labor costs. I am leaning twards keeping the v6 since well it needs a lot more work on the inside and it's going to cost A LOT. I need the interior cut out which is $120 plus $30 for shipping (My area is higher then mid west and east coast FOR some reason) The headliner that I want to get cause I'm NOT skimpping on this car is $170 it's $230 after shipping. Need a passenger door handle $20, got the locks for the doors and the trunk (though I can't get the trunk open) needs a new igition (Busted) new steering wheel. $50 (Cheap one with hub) Another bucket seat $150 And I know this is random. But does anyone have the problem where they are too close to the steering wheel when they put bucket seats in this car? Embarassing I can't see over the steering wheel and I'm like right up on it and it's really uncomfortable. Do they sell booster seats for adults?

But whatever, back to my point! This is my first carborated car so I'm learning a lot about there simplicity. But this is also the biggest body project car I have. So until I get my car the way I want it v6 for sure. Then once it's finished besides performance then it'll be time to think really hard on fuel injected 🙂

Thanks for the advice/info/opinons/stuff.

Odd problem, are you using factory type buckets and tracks? A few 5 nothing 100 nothing gals have driven mine with no issues, (actually comented how well they could see :lol: ). Although I have noticed these cars are long leg, short arm friendly, lol.
