EFI for Buick 455, what do i choose ?

Hi I want to install a efi system for my 66 skylark with 1972 buick455 engine, Edelbrock performer intake, KB C118 Camshaft, stock distributor with Ignitor 2 module, TH2004R transmission.
I am thinking about a "master kit" with "inline" fuel pump. Have been looking at MSD Atomic EFI, Fitech, Fast EFI, Holley sniper. They are all about 1200-1300 usd, except Fitech that are 1000 usd.
What will you guys recommend ?
What kind of alternatives are there if i will get a new distributor and install EFI with timing control ? And what type of distributor do i have to to use ?
Thanks

I have a FAST XFI 2.0,if you are interested. If your car isn’t more of a cruiser,one of the more basic kits will be fine.

 

If customer service matters to you… I would drop FiTech Based on what I have been reading all over the place.

 

Thanks Brian. Do you sell new or used Fast kit ?

 

I had a few kits and installed some in some of my cars. I have one kit here with no car. I started to install everything,and had the main harness in the car,but then sold the car without it,so I pulled everything back out.

 

Thanks. I think the XFI may be to expencive for me.

 

And if you read around on the FAST and Holley Facebook pages you'll see the same complaints about lack of service. Also if you read you will see that about 80% of the problems are the same issues of people not paying attention to details over and over and over again. The best advice I can give with any of them is 'to buy from a vendor with a favorable return policy like Summit or Jegs.

I've owned FAST and FiTech and in my experience both systems are fine if you do your home work and have your fuel and electrical systems sorted out BEFORE you start the install.

Do a search in the Hi Tech forum here at V8Buick and you'll find plenty of good info on preparing your car for a fuel injection system.

EDIT And now I see you live in Norway. If you are looking for best reliability and least amount of drama I don't think timing control is worth the effort unless you are running forced injection. Otherwise it's so easy to curve a distributor I would go that way. Also the external fuel pots or external fuel pumps tend to be of much lower reliability.

Seriously read about recommendations here from myself and others. Buy once and cry once.

 

I started a FiTech Meanstreet 800 install today actually. Do some extensive research and you'll find the biggest complaints with FiTech lie with the fuel command center. As mentioned earlier, electrical bugs can drive ya nuts, but thats with any system.

 

Really? ... I don’t know ... but, Fuel Command idea looked great, and stupid simple (lotsa plumbing)

Mechanical pump puts fuel in, electric pump forces fuel out

 

The fuel command center seems to work fine IF you modify it to have a full time return to the tank. Otherwise it builds up too much heat and causes problems.

 

^^^This^^^ Out of the box it seems to be a problem child. The modifications to make it work are pretty well documented, but I opted for an in-tank pump the has a proven track record.

 

xI have installed and run both the Fast easy EFI and Holley terminator units . the Fast on Sp1 and terminator on performer.
Both units have proven to be quite reliable in the case of the Fast it was after some learning (not by the unit but by me) We did drive this car from Canada to BG last year and it performed great .
I will make these recomendations from what i've learned. If you want to drive the car regularly pic a cam with more than 112 LSA
Idle will be solid brakes will work, tuning will be quicker .
Get one of these or similar https://www.aeromotiveinc.com/gm-a-body-stealth-fuel-tanks/ over kit pump more reliable , far less noise , will support more HP
We used 413 cam with terminator and performer Idled great out of the box about 2 weeks driving took it to the track ran 11's never turned a screw. Full street 72 skyark small valve iron heads thru mufflers.
they can realy improve drivability and driving pleasure when you make sure you take care of the details on installation(as Ken suggests). Cars will start almost instantly . no bogs
no flat spots decent fuel economy if you really care lol.

 

I'll be following this! I just bought a Fitech Go Street 400hp. I read some people had problems with the fuel commander, so I went with the inline fuel pump. The Buick has a return line already, so the plumbing isn't a problem. I haven't installed it yet. I can tell you it looks pretty.

 

Thanks for all reply What will you recommend, are thinking about Fitech or Holley Sniper. I think Sniper have a better controller display ? Will use with new gas tank.

 

There are four comon TBI system on the market. Fast EFI <- Cheapest , Holley Sniper in the middle and the holley terminator and Fast 2,0 are the most expensive.
The first two has all electronic build in the TB self, so they are exposed to high temperatures. The terminator & the newer fast XFI has a seperate ECU and can programmed with a Laptop.

I have chosen the Holley HP, it requires the most effort. But an MPFI system has the most tuning features, such as injector end angle, digital inputs / outputs PWM signal and alot more.

 

Just don’t confuse the FAST EZ EFI systems with their XFI systems.

 

Anyone using EFI like Sniper or fitech in combination with dual plane intake ? I saw a yotube video where hotrod tested Holley sniper for a a ls engine, and the engine wont run with dualplane so they switched to single plane. I have a 455 with edelbrock performer intake.

 

The FiTech is supposed to run ok on a dual plane but the Holley does not. Most people will run an open spacer under them either way. A lot of the benefits of the dual plane for lower rpm function is lost with fuel injection as the better vacuum signal to the venturi no longer applies. On a related note the downsides of a single plane for low RPM operation are no longer much of an issue either. FYI, The older V1 EZEFI also did not like dual plane intakes.

 

Thanks What choice do i have if i will switch to a single plane intake ?
