TBI Injection Upgrade for GW's

[Lippy]

Does anyone know of the guy who can build the TBI injection kits? Isaw his post here somewhere but cannot locate him. Also, is anyone familiar with his product and if so, is it good? Thanks

Off hand, I seem to recall a few people who make 'boxes' and harnesses for GM TBI's to be bolted onto just about anything... Once you got those two pieces, all you'd need would be a carb adapter (1/2" plate aluminum/steel/whatever you have lying around) some slight modifications to the fuel delivery system (remove mechanical pump, install electric + regulator) And Le Voila!

Have a look through the hotrod mag's, and maybe advance adapters website.

Ok I found it for you. His name is TPIGUY and he sells FI systems. Here is his mail... weg1192@aol.com . I'm sure he can give you all the specifics on his kit.

Guys, I've edited this post to remove the link to TPIGuy's page. His email is weg1192@aol.com, and he has expressed a preference to exchange information that way.

Sorry about the mixup, TPIGuy.

Since both my 79 and 86 use f*rd carb and ignition systems I have been wandering about adapting a f*rd 2bbl TBI system to one of them. The throttle body should bolt on to the manifold and the ignition should interface with the control module. It seems that this would be simpler than adapting a GM system in place of so many f*rd parts

I ordered a holley motorcraft 2300 2bbl adapter for my holley projection 2bbl system. I assume that it will work to replace my 2150 with the holley TB which I think is just a modified GM 2bbl TB.

I'll let you know if a week or two if this is the case when I try to install it.

[Puslinch]

The Holley is a custom unit, looks nothing like the GM TBI. I suspect it's a Holley 2bbl carb with the guts stripped out and a new casting made.

Bummer, thanks for the info.

By the way, getting a GM TBI system to work on an AMC 360 is more than just finding the parts in a junkyard and installing them. The main issue is getting a chip retuned to run the gas guzzling 360. The GM system, although good at selftuning, can't add enough fuel in stock form to run an AMC 360 well. It took me over a month to retune the chip to run my AMC 360 well. That time also included the spark timing.

Fooska,

You may be able to use Ford parts, but my understanding is that Fords chips are harder to reprogram, not impossible just harder. I have no trouble interfacing to the Ford Duraspark distributor on my GM TBI kits.

TPIGUY:

I wonder how your chips differ from the one included with the Howell system?

I understand that this TBI system will work on both 2v and 4v manifolds. What is the difference between the 2 systems?? ie. performance, bottom end, milage, etc..

Also, is there some kind of adapter for one or the other that would keep you from swapping the system from 2v to 4v manifold at a later date??

TPIGuy, there's a Dodge TBI setup available on eBay right now. What do yo think of this?

Hey wait a minute. This link worked last night. What happened?

Guy,

I saw that Ralph had posted my AMC 360 installation website on this forum. Since that site contains detailed information that I consider crucial to my kits, I would rather that site not be public information. I only provide that link to paid customers now. I will answer any specific questions by Email.

Gregario, I have a Howell 4bbl TBI chip in my possession. It came out of an ECM normally used on multiport TPI EFI. My research indicates that using a TPI ECM on a TBI setup causes some cylinders to run lean due to the injector firing frequency difference between TBI and TPI ECMs. But, when I have the time, I plan to test the TPI ECM on my Jeep with a TBI setup. Then I'll compare the Howell chip with my tuning efforts. Right now, I have my hands full filling orders for others.

Gladi8r, What I do is build two adpater plates. One is necessitated by poorly located holes on the 2 to 4 bbl adapter I buy. The other provides two TBI holes on top of any standard Holley square bore 4bbl manifold. In essence, its much easier to install a TBI on a 4 bbl manifold than a 2 bbl since what I do is first convert the 2 bbl to accept a 4 bbl carb. To answer your question, you would already have everything you need to mount a TBI to a 4 bbl manifold if you had one of my 2 bbl kits first. On the performance question, I had a generally smoother running engine, especialy at hiway speeds. It pulled a lot stronger at 80 MPH than it did with a 2 bbl carb. My mileage went from 12 to 15 MPG at 70 MPH.

I noted another kind of throttle body injection in the latest Jegs catalog, by Barry Grant, called VFI Injection. Anyone have experience with this yet?

I am surprised to hear that a stock GM chip will not function in a GM TBI System transferred to a jeep. It dang sure did on my recent 5000 mile trip from Austin, Tx to Portland, Or and back. Not a hickey.
