Outer Limits 4x4 Board

Im a mechanic by trade, work on zuks for a living. Can make a zuk or mits do anything, but know nuttin bout tojos.
One of my friends own an earlie petrol 80 and wants me to make it go better for him.
the vehicle is on gas, appart from the obvious of extractors and exhaust, what else is affective of making the vehichle go better.
it spends its life towing a trailer and whats hes chasing is better acceleration without affecting his off road abbiliy.
Any ideas be greatly appreiated.
Thanks

nothing btw, its a 3f... been there, done that.

simple drop a later model donk in there

then turbo it if your inclined

x 2.
The 3F was a 4.0l and the later 80's (93 onwards) had the 1fzfe 4.5l motor which was heaps better. Get one of them and drop it in. Not worth playing around with the 3f. Might want to check if the bellhousing marrys up to the original gearbox though...

dropping the 3F in the nearest harbor is about the only thing you can do to improve them...

I was going to suggest Cliff + Gravity!

you could go and spend 15g on it

10psi makes a 2f 100x better

harsh but funny.

even i laugh about a turbo 2f every time i drive it

Ill give him the good news, burn the car and buy a new one.
doing a 4.5 conversion costs too much cheaper to sell his and buy one that came factory.
Think hes a little annoyed that my paj eats him on and off road.

Who would be stupid enough to do that

2F+3FE+T+I-3F=2F-ETI

That picture makes me laugh every time i see it. Its a little cool but its highly rediculous in so many ways

matt.mcinnes wrote:2F+3FE+T+I-3F=2F-ETI

so does that actually work? and how much did it end up costing? and what do all the denominations stand for? ie ETI

That motor is what my $15,000 remark above was amid at.

Its a turboed, fuel injected shinny home for fish.

You forgot intercooled

E Electronic fuel injection
T Turbo
I Intercooled

Due on the dyno in a couple of weeks

Week tomorrow if all goes well but waiting on a custom surge tank.

Should be ready to play at the ATECO this year

Love your work Matt...the fish remark was Gold for the intercooler...you will need to catch them Golden carp and put tropicals in once its running...
Do u have any crank hoops set up under the sump??

You mean a craddle for the crank?

Here's a hint

i laughed till i got in it.

45 series troopies aren't meant to suck your stomach out through your arsehole...

and that was only at 6 pound...

you could do a cheap straight gas turbo setup?

yep. PCmans is an impco 225 (was a 200 when i saw it, and it was good for 10psi), a second hand skyline turbo (nissan of some description), piping, and an ebay intercooler.

mate, have just come back from checking out your fj40 website, very nice 2F indeed, a lot a work and $$$... how much power do you think you will get out of it?

The engine builder says were good for 400hp/300kw @ 12PSI from his calcs. (Scary)

However I am quite aware that the Crank even though cradled has only 4 main breaings. I think the Nissan stright 6 has 7. So we are pussing the limits of what a 2F can and should do way past what Toyota had in mind.

The build has however be a lot of fun and wether I fall flat on my face or not at least I have tried. I would be more than happy with 200hp+ and reliability.

The yanks have done alot of turboing to the 3f....it looks like you have done your homework, revs will kill it as opposed to the kw's Should be a stump puller, which is what your after.....
Impressive attention to detail

Revs are hard cut both fuel and ignition at 5500 by the ECU

5500 is 25% more than std. Is the crank 25% stronger?
Make sure this surge tank gets topped up faster than its used....no1 reason for turbo motor failure.....if possible, you should look for an efi pump in tank setup to supply the surge tank. There have been so many ppl with 304 efi in 3f 80 series that have come undone...fix was the 4.5 tank and pump or 3fe which is thesame.

I thought crank strength was more important when you took the "bang" (force per square inch when the piston fires) and not the rotational speed (where things like rod length etc is more important?).

there's a dude in nz that has a 7000rpm cutoff on his non-turbo 2F, should be fine from that point of view. i can see the mains walking or the crank snapping where there isn't a bearing supporting the crank (between 1 and 2 or 5 and 6).
