victor jr. efi conversion
Has anyone converted a standard manifold to efi? What would this cost to do? I would like to take off the tpi and run a victor jr. with a throttle body that looks like a carb and a carb hat. This is a 2400cfm throttle body. http://i157.photobucket.com/albums/t...k-T/c7_1_b.jpg what are your guys thoughts ?

Why not just buy something like a Super Ram instead?

Yes, just like that. Actually they even have the vic jr drilled already for fuel injectors. I just don't think it's worth the $400+ when i can get a carbed vic for around 100 and brill for the bungs myself. I am just not that good at welding aluminum.
As for the super ram everyone has one. I thought i try something else. That and the price of one of them is just not worth it to me. I can get just as much out of the singal plane manifold for a lot less cost. Over on the turbo forums guys are putting up some seriuos numbers with a blow through set up. I thought i'd go that way but with a twist. Besides the super ram is only a 1000cfm if i remeber wright. That throttle body was listed as being 2400cfm and fast also puts out a 1300+cfm one also.
With me i like to do all my own work. I am the one that has to be differant (difficult).

It should work just fine. You may even be able to get away with using an old carb and retrofit a TPS sensor onto it. That would probably save a bunch more money, just plug the fuel ports. I guess you might have a problem with the IAC, perhaps you could figure something out for that, I'm not sure what old carb motors did.
The fun part would be mounting the figuring out how to mount the fuel rails. You'll have to make some brackets. Just make sure all the bungs are drilled at the same angle and they should go in nicely. A new tune in the ECU and you're good to go.
You should be able to put the MAP sensor on a vaccume line to the manifold so that's not a problem. Sounds doable to me, just make sure there is enough hood clearance for the carb and the aircleaner.

There are basically two routes you can take. (this is an LT1/4 car right) You can either get a Victor Jr E...fuel injected version...already comes with bungs for injectors, or you can take the cheap route like I did and buy a Victor Jr on ebay for $100 and buy the bungs and have them welded in. A lot cheaper that way. Either way you will have to be creative to mount the rails so that there is clearance under the stock hood, but it can be done. I used a Hogans 90 deg elbow to adapt the TB and an accufab 90mm throttle body. This will WAY out flow the 1300cfm mono-blade and drivability is really good. They sell the Ford to GM tps adapter and they also have the adapter for the IAC. Basically plug and play and it all works great. I know this is vague, PM me if you have more specific questions.

Actually it is a l98. Dose the l98 have a iac? I don't know this is the first chevy v8 i have own. The car i sold to get thi was a 92 eclipse awd turbo. I am deffenetly going to go the route you did. I can use a drill press at work and i can get a bung and fuel rail kit for $100. This way i still be way ahead instaed of buying one set up already.

There are good threads about EFI singleplane intakes on lt1´s at camaroz28.com.

97Aggie where do you get the bungs to be welded in and what does the Hogan elbow run?
The one thing I've never had answered for me is, is a carb single/dual plane flowing as well when converted to EFI as it does stock, consider that the flow is now just air vs the original design of "wet flow".
