No I used both 02 sensors run one after the other, no CEL or anything, just used one modern ODBII cat versus the two old OBDI cats.

Uh, what is CEL? Using a single cat here too but didn't realize there was an OBD designation for a cat. My O2 sensors are located in the two separate pipes before the Y. The thinking there was that more accurate feedback can be given to the ECU as opposed to two sensors side by side in a single pipe.
 
CEL = Check Engine light, sorry its a term used for the audi's alot. What is ODB designation? Every recent cat has one, new ones are ODBII compliant.
 
I bet you could install a FI 350 cheaper than you could mess with that 3FE.

Quite probably true. So? Different strokes(!) for different folks. I prefer TOYota to Chevota for the kind of stuff my truck goes through - I don't pull trailers. I have wheeled with Chevota 62s before. Not my cup of tea. Great for other's though. To me it is sort of like the "lifetime guarantee" that some rebuilt parts come with. What good is the guarantee if you are having to replace the part every two years or so? OEM Toyota lasts a loooong time.

Any thoughts on this setup:

Some of the procedures performed during the engine build:

Bored .030"
Decked .012" (to get 9 to 1 CR)
Crank grind
Resize rods
Bigger cam
Complete balance to within 1/2 gram
All new valves
All new guides
All new upgraded springs
Head milled .030 (to get 9 to 1 CR)
Non USA 3F in/ex manifolds (big improvement over stock 2F)

WORD!

our bone stock(but 33x9.5's and ARB bar) and two owner(1st till last year) 90 fj62 has ran well sense we got it, did a basic tune up right away(plugs cap ect ect) and it was prolly the most powerfull 3fe I have driven(and have driven alot, owned one for 9 years), but now that a VSV sensor and the EGR are replaced it just flat hauls butt and purs like a kitten, no ruff idle....no crap it feels almost like driving moms 97fjz. I LOVE driving it, Connie is just flat out exstatic and she had been driving my 2000 UZJ.

did I mention this is with 241,000 miles on it? :D

So YEAH, before you go nutts, make sure what you have is working as well as it can.........because it will suprise you what it can do.......for a tractor motor ;)

(BTW DD, even 89 fj62 shows the power pack as optional and AC, looked last night)

before youy get all gung ho on the super rebuild spend a few hundered bucks and a bunch of time and tune your existing 3FE.

Man I can respect not wanting to venture into non Toyota territory, but you cant be serious. If there is a better, longer lasting engine platform out there than the venerable Chebby 350 I dont know what it is.

Dont try and tell me they arent reliable, because there isnt a better engine out there.

Now Im a diesel guy, and I have a diesel 60, but outside of diesel nothing beats a Chevy 350.

I'd like to beef up the current motor actually, been saving input from post, as you can see I asked about the 3FE beef up, not dropping a Chevota in there...

saw TPI's headers.. having the maintence items done first and the air intake... than I'll see what else I can do for cheap..
 
Headers

sourcemine,

I hate to burst your bubble but did you ask TPI if those headers are Cali smog legal?
I have the same set but from MAF and they didn;t have any CARB numbers so that makes the headers on my 3FE California smog illegal. I would spend that money on the throttle body and intake manifold enlarging from RC engneering, and also do some porting work on the exhaust manifold and head. Then replace the exhaust with a freer flowing system, but not too free flowing as that will hurt low end torque. There you will need to retain the 2 O2 sensors and the 2 cats to pass visual smog inspection here in Cali. I have raised compression and that has a good effect on performance. (No, I am not saying that the 3FE is a race motor now, just saying it has a little more power now) I am headed towards the throttle body and intake maifold enlarging, along with an injector service since my injectors have 300,000 miles on them.

I just passed smog with 1 cat, so that's b/s, I got my tags today. How come nobody on here gives links to websites... if your going to post about a company, POST A LINK.. please..

I already did the exhaust, I'm also doing the TLC air intake, and I'm open to other items.
 
aside from proper tune the h55f is the best improvment i've seen. The '88 i built for my wife has 33x12.5s and stock gearing w/the 5 spd and it hauls for a cruiser(dd113's driven it). fourth up these mtn. passes is not a problem at hwy speeds. the motor doesn't work near as hard as it used to. no more wrapped out in 2nd going up hill!

Yep. Tune up and an H55F made my 60 highway driveable.

sourcemine,

<<<I just passed smog with 1 cat, so that's b/s, I got my tags today>>>

Just because you got your car smogged in the ghetto doesn't mean that what I stated is BS. According to the CA smog laws you need to retain the stock configuration for the exhaust to pass a visual inspection. A guy on one of the message boards just failled his CA smog test not because he didn't pass the test, but because after he passed the dyno test the smog tech wanted to check the timing. When he couldn't find the timing marks, he failled the guy. Did you take the test on a roller dyno? If you didn't then you are in an area that still does the old smog test. If so, you are lucky.

<<<How come nobody on here gives links to websites... if your going to post about a company, POST A LINK.. please..>>>

Most of us are not lazy, when we want something we search for it not ask for it to be spoon fed to us. These companies are well known amungst cruzer people. If you are looking for:

Man-A-Fre: http://www.man-a-fre.com/,
TPI: http://www.tpi4x4.com/lc1.htm,
RC Engineering: http://www.rceng.com/index.htm

I found these places by typing the name of the business in a Google search, then clicked on the link when the search came back. Not too tough. I would recommend Man-A-Fre.

H55f

Mike S and sanjuancruiser,
I want to convert my FJ-62 to the H55F but I have been hearing about the added ~2:1 the auto tranny supposedly gets you during low RPMs. And how the 5-speed is a disadvantage off road. I was comapring ratios and the 5-speed is the way to go in every situation. How does your H55Fed FJ-62 compair to the A440Fed FJ-62 off road? Did it seem like you had more power at lower RPMs with the auto? I don't completely understand the fluid mechanics behind the torque converter theory, but aside from that the H55F is the better tranny in my opinion.

I swapped my stock FJ60 4 speed for an H55F, so I cannot compare it to the same truck with an automatic. I selected the FJ60 because it was the last year Toyota imported a Cruiser with a manual transmission to the US. I do NOT like an automatic for off hughway use, and certainly not for off road use. Just doesn't suit my needs.

The H55F mated to the 2F seems to perfectly compliment the 2F power band, and it preforms very well both of and on road. The difference in highway driveablity is tremendous. At 75 mph, I am running under 3000 rpm (about 2800 or so). At these speeds in the old truck, you need to have well set up suspension, tight steering, and so on. As I mentioned in another post, I added the rear anti-sway bar, whoch makes a big difference in handling at speed in the hills. The diffs are standard 3:73 and I am running 31x10.50x15 Goodyear MT/Rs on stock rims. I am sure I would get a bit more power to the wheels with the 4:11 gearing that a 62 has, but would give up a bit of top end. With the H55f's lower 1st gear, there is no lack of pull at the low end.

I am still working on improving performance of the 60, and am reading this thread with great interest. Every little bit of improvement helps, and is noticeable in driving - especially in the hills.

I agree, my truck hauls ass with the H55F on 31's. I have a similar engine to overhanger but no snorkel. I have, accidentally, gotten rubber in both 1st and 2nd gear. My rmp's are too high now so I will do a rubber re-gear to 33's to drop them down. Make sure your TPS is adjusted properly and spend the $260 for a overbore TB from RC. Well worth it.

My H55F conversion cost about $3200 using a new H55F, clutch, master, slave, etc. and a bunch of used FJ60 parts. Done in my garage.

My 3FE rebuild cost about $2500 using new OEM pistons, cam, oil pump, etc etc. I balanced the rotating assembly and its overbored 40 over. Oh, and Jim Chenoweth built my head using chevy SS valves and did some P&P work. Flowmaster as well.

I did all the work except the machining. The machine shop assembled my long block for an extra $200 and they had done many 2F and 3FE's so I let them!

Biggest performance improvement: H55F! Overbored TB next.

I do not need a V8 in this truck it hauls ass! If you do not want to go manual get an extreme A440F from Slee and put your foot in it.

Dunbar, Sounds like an excellent set up! How did your 62 t-case mate with the HJ55???
 
Rollin'in'Zona,
I think Dunbar means that he put the Toyota 5-speed manual tranny ( model # H55F ) in his FJ-62 using the stock T-case. If that is what you thought then nevermind. I am doing my research about the conversion and you can mate the FJ-62 T-case to the H55F transmission, from what I've been told.
