I think i want to get a TBI setup in my vette, Its a 84 and it just runs like crap, its lean the gas millage sucks and it doesnt even make good power.

That being said, TPI not for me. I want to rev this damn thing up.

So im looking to reuse some of the parts from my ceasefire like the injectors and such get me a TBI intake and setup some sort of new computer..

So on a budget with gas millage and power in mind, What would be my best option? Im pretty sure i need new heads but its not like i will miss the crossfire heads..

Oh id like to keep my factory gauges too if possible.

I used a holley projection on my 84 vette. with GM 7.4L TB unit.

 

dont forget the EBL Ronny

 

What's so beasting about the ebl? Wouldn't a chip burner serve the same purpose?
I meself was looking at an $85 chip burner from Craigs website.

 

I did the tbi swap about 10 yrs ago, haven't missed the cfi at all. A single 2 barrel tbi will let you use a conventional 4bbl. intake.
I'd use a performer intake w/ a tbi adaptor or the holley tbi intake. The holley comes in either convential or 87 up bolt pattern. It also comes w/ throttle/tv brackets, egr block off plate, & hardware.
Get a tbi off of a 87-89 350 chevy truck, the wiring from your car will hook up just fine. You'll only have 1 iac valve, it should matter, mine idled pretty good that way. You'd want to do the ultimate tbi mods w/ an adjustable fuel pressure regulator. I used the stock ecm & haven't had any issues, gauges work the same & still get decent mileage.
Hood clearence is tight, but not impossible.

 

EBL one time install put the computer installed. now you just hook up a wire, can reflash in 3 seconds. Chipped car constantly installing..uninstalling...disconnecting the battery...removing the chip installing new chip etc...then depending on the chip to erase it is a pain but if thats the way you want to go that is fine.

 

can someone give me a link to the 4bbl intake to TBI adapter plate? i cant find it anywhere. Its good my stock ECU will work for now.. I do plan to swap it out, what would be my best option? I am considering megasquirt but im open to cost effect options.

ex-x-fire, what are you shifting at in your car? curious as to what other mods you have as well.

Thanks!

Ronny is that a MAF on your car?

 

I ran the stock ECM for several years on a not even close to stock motor and tuned using the Moates equipment. I have EBL now and it is certainly a big step up, but imo one could have a decent tuning setup with the Moates stuff.

You can avoid a lot of the installing and uninstalling that UnderCover89TBI mentioned by getting the right combination of adapters and ZIF socket from Moates. You still have to physically swap chips though unless you get something like the Ostrich.

The rub comes in when you total up the bill for all that stuff - sockets, adapters, chips, burner, Ostrich emulator, etc. I had it all and by the time I was done I could have just bought the EBL from the beginning for the same money and got to use all the advanced features that the EBL has.

 

it seems to be EBL is a bit over priced, you can pick up megasquirt for less then half the cost... why EBL?

 

Jay7199, I shift at 5800-6000 rpm. Its a th700r4 w/ 3.07 gears.
The mods that I've got are TF 23* heads (big valves), hyd. roller cam, 1.5 roller rockers, 2" holley tbi, smoky sy1 intake, msd igntion system & an open element air cleaner..
I am running the origanal exhaust, its in good shape for a 28yr old system, so I have a restriction there. I also ported & coated the stock shorty headers & removed the air pump too.

 

No it is TBI...speed density. EBL is the ECU.

 

why EBL? Go to their website and read up. In fact the first EBL thread on DIY-Prom is the intro to its availability. It is more than an ECU it is a tuning system. MS I will say is a ECU.

What is the cost of MS? Fully assembled? I believe it requires a change in your harness or an adapter?

I will say MS is for advanced users. EBL is for same or beginners.

 

The megasquirts that cost less than the EBL do less than half of what an EBL does, programming is a lengthy & awkward process, they are not self tuning, the whole board & connection system is a fragile assembly compared to GM's, RBobs insightful codework, I could go on & on.

Did you really add up everything you have to buy to use a MS? I didn't think so.

The MS that actually does what the EBL can, costs BY FAR more.

 

I found a stock TBI intake, What would it take to get it to bolt up to my 84 block? If im not mistaken the intake bolt pattern is different when they changed them up in 87..

 

I haven't done this, but you can grind the center holes to get the proper angle. I'd just get a performer intake somewhere, hell the new ones are 115 bucks or so.

 

Im on a tight budget, My vette is my daily and im looking to improve fuel economy and reliability with a slight increase in power. like i said im running really lean getting 13mpg and over all just crap with the crossfire. I could maybe rationalize a performer intake down the line but for now i just want to get the TBI on and running well.

My main toy is a LT1 trans am and she takes all my money :_: lol

 

Money then is better spent on rebuilding the stock TB's having injectors rebuilt or exchanged for same and keeping the stock computer. Do a balance on the TB's as well.
