Default EFI or propane??

Im about sick of carb problems and its time to jump the fence. Im currently running a 2bbl Holley 350CFM with the Downey adapter. Its ok, it makes more power than my previous 300RGM progressive 2bbl, and way more than the OEM carb, but itís still a carb. Im sick of dealing with carb related problems. If its not one thing its another, every freakin shop selling aftermarket carbs for the 22r will tell you there carbs are plug and play right out of the box (WTF ever)??? My wide band O2 says otherwise. Im using a LM1 with AUX box to tune (MAP, AFR, RPM, EGT, and accelerometer).

Anyways, the question is what would you convert to and why. Propane would give me a dual fuel option which is great. EFI is cheap and I can buy gas anywhere, I think I can get an EFI swap done in one day. A propane swap would require a bit more in time to fab things and money for parts. This is my daily driver and I commute from Wayne to Warren every day so ultimately reliability is the #1 factor for me. 87 pickup, 31ís 4.10ís. Next step is 4.88ís trutracs and 33ís. EFI or BBQ???

I would not put propane on a daily driver. The end.

I'd also say EFI.

I chucked a junkyard 22RE into my truck 2 years ago, and have had zero issues with it since. (1985 truck, 1985 motor).

I need to do some tune up and clean up on it (some idle issues, but the idle valve is clogged up). But it runs great.


Or since you have the tuning crap, slap a megasquirt and a junkyard TBI unit on there....

Stand alone is great but Im not sure I want it in my DD. If I do EFI its going to have to be OEM all the way. Stand alone is great but not worth the headaches if you depend on it as a daily driver (IMO). Im leaning towards EFI.

I found an EFI set up that includes harness, injectors, TB with TPS, intake's, MAF/air box and all sensors for $200. Its off an 88 4-runner.

I believe I have a complete EFI setup in my barn at home. I can check tonight, it would be from an 88'.

I would be much abliged if you would check on that. I dont have any Toyota EFI expeience but its all the same in theory. My only worry is that my lack of Toy EFI experience may cause me to inadvertantly source an EFI set up that may be less than complete. Then Im left searching for bits and pieces....

If you have the EFI and want to trade for my Holley 2bbl set up..... Yea I didnt think so.... I actualy got it running pretty good after down jetting and reducing the the size of everything including the PVCR.

I'm going to swap over to EFI this winter, I think. I also have a complete extra EFI setup for a 22re.

Yea I have come to that conclusion (x3), and thanks for the help on that. It is tempting for the wow factor but... Cant beat OEM for daily driven reliability.

It will be for sale here pretty soon, pending the EFI install. It took some time to dial it in because its factory calibration is small V8 or V/I6 application. Everything was way too big. I even had to employ some power valve cavity restrictor orifice tricks to get WOT in check. It was choking out with too much fuel even with #56 mains. Now it hauls ass, I’m really impressed with the performance compared to the two previous carbs.
Holley makes a truck carb in there avenger series. It’s all tricked out for off road application. They make one in a vacuum secondary 470 CFM 4bbl that I would love to get my hands on. I bet I could make that carb rock on a 22R. I’m actually very surprised that no Toyota aftermarket companies have tried that carb on a 22R yet. I think its coming. http://www.holley.com/types/Truck%20Avenger.asp
