I'm struggling to decide on an EFI set up. I know ram intake is probably best but for an old Camaro like mine, I'm starting to debate if a a carb style set up would be a good idea. I know people sell intake manifold with injectors in each individual runner with a carburator style throttle body. So I'm wondering, if I get one of those manifolds, could I plug up my old carbs fuel inlets and other fluid inlets and just use the carb as a throttle body?

 

How would you incorporate a iac and tps ?

 

I don't know for sure. Are there any bolt on sensors out there I could use?

 

Probably better off just getting a 4150 style Throttlebody. Accel use to make a ford style remote iac. But you would have to rig up a tps mount.

 

I'll have to check, but I think the TBI out of the 1994 Suburban I recently gutted might have those sensors already.

a 4150 tb is a better deal

What ecm will you be tuning with? Could go with your tbi but it will be a restriction. What’s the build ?

 

Don't do the carb thing, just use an EFI throttle body that fits over whatever hole comes out of your intake. Honestly it's hard to beat a dual plane for a street car but vertical packaging becomes an issue under stock hoods pretty quick.

 

I plan on going with ACES EFI Wild Card standalone system. I also plan on getting a late Z28 style hood, cut out the hood vents and get actual vents installed. I'm not too worried about air flow, that's an issue I'll resolve relatively quick.

 

might want to research the quality of their products

 

I have, seems they're mostly good. There are some issues but they're rare.

 

 

Damn. Any other brands good for the build and on the pocket? Holley is just too much and I don't really know of any other brands that are budget friendly and reliable.

 

Fitech is no better than ACEs. Holley is pretty much the way to go. I'd just save a while and get the best the first time rather than spend the money twice

 

You get what you pay for. It’s cheap is the only thing I’ve seen going for it. Fitech seems to have better reliability. Just depends on your build and budget. Not sure I’d want to try any ace products.

 

Well, I already got the transmission control module. Should I get a refund and go with something else for my 4l60e?

 

I think you could use a carb...and you could use the carb's TPS and forgo the IAC, IMO. At lease initially.

 

it could work fine, going cheap on efi might just be a headache you can avoid.

 

The idea is to do everything in steps. For right now, I'll be running everything carbed. Next step would be introducing very basic EFI, just enough to get things running. Later on will be upgrades to the system to make more power and be more efficient.

 

I've had 2 edelbrock systems that have been great. I have 3 friends w edelbrock systems that are really happy w them. The pro Flo xt doesn't have hood clearance issues! All of it fits under a stock hood. When my car was tuned, the tuner and dyno operator both felt the edelbrock and Holley products were great. They both are really similar at this point according to them. The dyno operator used to work for FI tech and thought their products were also good. This is a get what you pay for situation. If an efi system is pieced together w a bunch of different pieces for different brands what you save in money will be quickly outweighed with headaches and issues w drivability (assuming you get that far!)

this intake fits really well and the system has been great.

 

Totally agree, never piece it together. That just calls for problems.

 

well said, that’s a masterpiece of a build

 

Yeah. That brand is General Motors. The real GM that died 15 years ago not this new gm.

They produced the best and most reliable Throttle Body Injection system on the planet that bolts right onto a SBC or BBC engine.

You already had/have everything you need to do a powertrain swap on your Camaro.

You have a PCM that is lightyears ahead of the ECM that controlled the TBI system in our 3rd gens and it can control the 4L60E transmission that came in the 1994 Suburban just fine.

 

What modifications would I have to make for the suburbans ECU to work in my Camaro, if any? I did debate just taking the full EFI system out of the suburban, just wasn't sure of what all I'd have to change to make it work.

 

Do you have the entire 1994 Suburban to rob parts off of?

 

Yep, it's just sitting right now, waiting for someone to buy the shell off me so I have time to steal more parts from it.

 

You won't need to modify the ecm from the sub. Just grab everything from it and swap it over. You may need to extend some wires but it should be pretty easy. Just label all the stuff. You can use the power wires for the stock ecm to power the ecm from the suburban. Your fuel will be the largest potential issue. You'll need an in tank fuel pump and depending on what your current setup is you'll need to potentially make some changes. The tbi systems require lower fuel pressure than other systems. The sub ecm will trigger the fuel pump/relay.

using the whole efi system from the sub is the move for your need. It can be run as a standalone efi unit w a little work. That system doesn't care what car it's in. There is also a ton of support when/if you need help.

 

You will need the Suburban's PCM, all the wiring harness connected to the PCM and the engine, transmission, and under hood wiring harness too.

It probably wouldn't hurt to get a 89 or maybe 90+ TBI Camaro parts car too.

You're going to convert your 84 Camaro Berlinetta into a later model TBI Camaro while also integrating the powertrain, PCM, and wiring harnesses from all of them into a new wiring harness.

 

Got any recommendations for fuel pumps? I can't seem to find any pumps with the PSI range low enough to not flood the TBI.

 

Just get a pump for 89-92 tbi fbody . Im
guessing you have a 16197427 ecm. Not to bad to make it into a stand alone harness. Gearhead efi has the pinouts and schematics. If pressure or volume is to high it doesn’t flood.

 

I'd get a "TPI", or MPFI GM application fuel pump...that way, when you upgrade the EFI system later, you already have a sufficient pump in the tank and don't have to $pend twice on a pump. It will not "flood" w/a MPFI pump; the regulator sets the pressure and the injectors administer the volume...not the pump.
