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

[pappy]

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?...

Well, I won't say it's that simple. See here:

Don't forget the fuel system and ignition system too, have to agree with Pappy though, it's not quite so simple but neither is it a huge mountain once you get into it.

Im pretty mechanically inclined so im not worried with the ignition and fuel stuff. Im no professional by any means and i still have a lil bit of time left before i do this so i will be reading up on it as much as possible to figure it all out. I just wanted to know if it would all basically just bolt up w/o much trouble.

thank you for the link though. I will read through it here shortly and save it as all info helps go to the cause.

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.

I beleive anything after 4/85 they have the domes pistons.... just like the clutch slave cylinder is dif on a 60 as well as the clutch master cylinder bolt holes.

ok i know its an old post but adding my input for future reference.

This statement, "mid-1980 the pistons used went from flat topped to domed", is wrong. A bit of dyslexia on my part.

The pistons in the early 2F's were domed, the later 2F's had flat topped pistons as did the 3F's, and the change did take place around mid-1980. So unless an engine has been swapped out any FJ60 should have a 2F with flat top pistons.

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.

The 3.1L shares its TBI system with its precursor, the 2.8L, which has never been held in very high regard.

IIRC, those TBIs only had 1 injector, as opposed to the 4.3L having 2. The wiring harness & computer would then be designed to operate this much smaller engine, using only 1 injector.

As I understand it, the 4.3L is close enough in displacement to the 2F to be more compatible.

Also, there are a lot more 4.3L vehicles out there, from 1986-1994(?).

All done so it's now a real world story.

You should be proud after all that work. But quit showing off


UPDATE ON REAL WORLD 2F-E experience:

I recently installed a performance grind cam from Delta Cam in the 2F-E. It really woke that bitch up! I'm now working on my own cold air intake, not that it will help much, but if I can get 1 more pony then that is one more pony

+1 on a good camshaft to feed the extra cubes.

The stock intake is already pretty "cold air" since it pulls from the inner fender area. You can route it through the firewall (which is what I did) or get a snorkle. However what you really gain from an aftermarket intake is smoothing out the intake ducting. My experience is that this does make a difference. Small but noticeable. Also if you haven't already upgraded your ignition that will provide some additional small but noticeable gains, particularly at highway speeds and full throttle.

I'm just playing around with things like a CAI. It's true that the stock location already takes air from the fender area, but that fender area is open to the now hotter engine bay of the 2F-E. My main plan here is to close it off more so that the cooler air can come in. It may make a difference, who knows. I may be wasting my time too, but I have to try right?

I've thought about ignition stuff, but I don't really know what to buy, or what to replace.

Sorry, that came out wrong. I wasn't trying to dissuade you from experimenting, I was actually trying to encourage you to do it and to incorporate new intake ducting all the way to the throttlebody for the maximum potential gain. I just meant don't be fooled by the aftermarket intakes that stick an open air filter inside the engine compartment and then call it "cold air".

I have run both the MSD stacker box and the Performance Distributor's ignition. Both have about the same gain but do it differently. The MSD adds a CD spark on top of the stock inductive spark, the Performance Distributor increases the dwell of the stock spark resulting in a stronger spark. Both provide a nice pick up particularly for scenarios like merging.

The MSD is not compatible with my J&S Safeguard (aftermarket knocksensor/timing control) so I moved to the Performance Distributor setup (if you are interested I'll sell my MSD unit, I'm not using it). I used both with an MSD Blaster High Vibration coil (Performance Distributor said that this was fine for their ignition).

Spook also runs an aftermarket ignition that he is happy with.

No I understood you, those CAI kits are BS most of the time. I'll post up what I end up doing if it ever quits raining here!!

I saw spooks setup. I didn't think to ask him about it though. I was mostly at how small (short) the 3F-E really is.

Did you ever end up working over the intake?
