2F with 3FE head/injection? Real world stories please

[lowtideride]

I have a spare 3fe that I want to use for my 2fe set up...

Anyone have an estimates on how much this will cost? I need to get the 3fe head to a shop for a valve job and cleaning... get most engine seals and rings..

I have had this idea on the back burner for a while and am excited to do it, just have plenty of other projects to do ahead of time.

I have a nov. 81 2f in my cruiser, is that too early of a 2f to mate up to the 88 3fe head?

No mines a Oct 80 2F that I can use.

Cost mmmmm all depends on what you want to do.

You can add a cam and over bored throttle body and computer adjustments to the 2F-E and it will run perfect also. I hear ya on the parts, but I haven't really needed anything for the EFI.

Not saying your wrong,, how can you change computer settings in the 3fe computer. I sure didnt think you could, other than small learning capabilities. The ecu will not "learn" a new camshaft, change spark and fuel tables. How is this eprom flash done? Just curious..

Pretty sure that would be within the learning capacity of the 3F-E ECU

I would really doubt it, but I could be wrong. Cam swaps on any other efi'd vehicle on the planet need programming.

Sounds like from Tom Quinn's page (http://www.tomquinn.com/lc/2f_fi/index.html) you could find a way to reprogram the eprom. Might take more trial and error than most are willing to put up with.

Mark W. puts in performance cams into 3F-E wagons without issue.

Do I have right stuff?

I have a 1992 Isuzu Rodeo with 173K on it. Had it since it was new. It's day is almost done and in Montana it is not worth much because it is 2WD. So, I have been told that it has a Chevy engine in it...V-6 3.1 Liter. I believe it has a Throttle Body Injection system. The engine runs great (trannys starting to slip, valve covers leak, rear brake anti lock light stays one). My question is: Do I have all the right stuff to put the TBI on my FJ60 2F?? Help me, I am totally clueless about anything that is run by a computer.

The Rodeo also has nice seats in it which could be salvaged.

There's a fair bit of flexibility in the 3FE EFI system. The AFM can be tweeked for more fuel, the injectors are a standard top feed and probably match something used in GM or Ford vehicles if you need more fuel than the OEM injector can deliver. IIRC Howell can reprogram the ECU as well (if not I'm almost positive there is someone who can). 3FE's are desmogged and timing advanced on a regular basis without throwing codes as well. Don't forget: a 2FE is a bored and stroked 3FE. Lots of EFI systems don't take too kindly to that kinda mod either! I think all I did was open up the idle bleed screw on the throttle body to account for the extra air the bigger motor needed.

Heck, if I could have gotten the TBI conversion to work well I would never have bothered with the 2FE deal. But now that I have a 2FE I'm not too interested in going back to TBI. YRMV of course!

Interesting, I guess if you have done it its possible . I think anything other than my weber is a great idea;p

Well, guys I've read this thread and the article by Arron acouple times now. Excellent article BTW, and I'm thinking this may be the way for me to go. I rebuilt my 3fe last year but have been frustrated with the lack of power up the hills, especailly when loaded up.

I have a some questions.

1) In the article the 75 2F was ditched. I'm thinking the best year for the block would be 85-87?

2)Any ideas on locating a short block other than watching the parts ads here on mud.

3) If I had a complet 2f engine with bracketry, would that eliminate the majority of fab work?

4) You haven't had any rub issues on the hood?

Thanks in advance.

A block from '79 on up would work. You want one that has provision for mounting the power steering pump. As for the best year then looking for one from the later years would be best. Somewhere around mid-1980 the pistons used went from flat topped to domed, although swapping out pistons is easy. There have also been some minor changes to the blocks between early and late and I know of one instance where a water pump stud has been discontinued for the early block.

I haven't done the swap but I would think that having the bracketry would eliminate some of the fab work needed.

Underhood issus I belive are more the 80series not 60's

Any 79 plus would be fine, I called a Toyota wrecking yard to find my 2F block.

It's not the brackets really, but the stock location of the FJ62 vs FJ60 accessories. I didn't want to reroute any thing, so I made the simple little brackets.

The hood liner rubs, but its not bad at all. There is a shiny spot on the EFI tag and that is it.

If you do this, I recommend getting a cam from Delta cams. You'll need to have one ground anyway. Its the one thing that I skimped on and I wish I wouldn't have.

 

[pismo62]

Thanks for the responses guys,

So a stock cam that had minor grinding on the rebuild won't cut it. What would be the advantage that I would be looking for with the new cam? More low end torque? That's past my knowledge level. Please enlighten.

When you say the toyota wrecking yard, can you be more specific. Thats a new one for me. Did you take a short block and have it rebuilt or did you just find a low milage one and swap it in?

Thanks for sharing the knowledge and experiance.

 

[tonkota]

Well, a stock cam that is reground may be ok, but I reused my old one with new lifters. Its out of whack now and I feel like a dumb ass for not spending the $60 to get it done right.

Well, there is Nix99 in the seattle area that deals heavily in Toyota stuff. I bought a short block from them and had it machined and then rebuilt it myself.

There ought to be an import wrecking yard around your area.

 

[pismo62]

Thanks for the info. this sounds like a worth while project . Now I just need to find the time. And a 2F block, which I already have a lead on.

 

[CruisinFJ60]

so if doing this to a 60 would i be able to keep everything in the same location as factory w/o any neat little brackets?

 

[pappy]

I have my alternator, power steering pump, and in theory smog pump (MIA) in the FJ60 locations on my engine. I assume AC wouldn't be a problem either. The only issue is routing of the coolent lines from the thermostat housing as the 3FE does something different than the 2F.

 

[CruisinFJ60]

ok this is what i was wanting to hear!

coolant hoses shouldnt be all that bad i can make something work or have them made quite simply i think.

so basically all i would have to do (in theory) is bolt on the head, run the hoses for coolant, put the computer someplace, and plug it in and go..... Right?...
