Waiting.....somewhat patiently for an update :cheers:

Incredible work, love the ingenuity you have brought to the build!

Well progress has slowed, but the old engine will all been well be out tomorrow and the new going in.

The gear box is back and looking like new again.

But we are getting there.

Once the new engine is in place we will then fabricate the intercooler mount and mount the intercooler before sending it off to have the all the turbo and intercooler pipe work fabricated, as well as the manifold from the headers to the turbo mounting. The Plenium will also be mounted and in place. Basically everything will be in place so there is no interferance later with the pipe work. Surge tank has yet to be custom made to fit a spot I have planed for it. So still lots to do at least a month away from turning the key maybe more.

Have elected to mount the inter cooler on a couple of these vibration dampers now just to fabricate the bracket up.

Hmmmmm

Okay the good news

100_3682.jpg


The bad news

The differences between the 2F and 3FE thermostat are such that neither really suit my needs.

The 2F does not have an out let for the heater previously it came from the block, the 3FE head does not have this option :mad:

The 3FE does not have the connection for the hose from the 2F water pump:mad:

For those that have already built a 2FE how did you over come this?

My best solution so far is this.

You need a heater? Impressive comp rig with mod cons. I had a look at the stat housing sometime ago and it set me thinking about a "remote" housing, no need at the moment but in the future I might need to revisit that.

I have never been south of Sydney and it was "summer" when I was there but how cold does it get in winter for you?

From my visits to Oz, so far Brisbane seems to have the ideal for me, not too hot that you feel lethargic all the time and really mild "winters".

Melbourne in winter is not too bad but the ski season in the Alpine region about 5 hours away is pretty good.

Your point about the heater is valid though it's not essential but a pleasant luxury in winter at the Alpine Challenge.

The solution I have seems promising using the bottom of the 3FE thermostat housing and bolting the top of the 2F thermostat housing to it, they do fit too:clap: The bottom accommodates the temp sensors for the Gauge in the cab and the ECU and has the output for the heater, the top section has the connection for the 2F water pump. The only bit in question is the small feed pipe off the the heater out let which originally feed the EFI plenum but this may yet feed the Turbo.

Ok thermostat update

100_3689.jpg


As you can see the one on the left from a 79 2F has 2 bolts holding the thermostat housing together the one from my 1980 2F has 4 bolts on the right.

The thermostat for the 2F and 3F are listed as the same part the 3FE is the same dimensions but runs 190 rather than 180 so I'm told. So I bought the 2F one s I would prefer to run cooler.

:mad: I got home to find the 3FE one I was sold is a 180 not 190, you reckon they did not have a 3FE on the shelf and thought what the heck :censor:

The good news is I can bolt the 3FE bottom and the 2F top together as the thermostat has same dimensions and bolt patten.

So problem solved I just have to figure out where to feed the coolant line back in from the Turbo, small issue:hmm:

This would not suit a 2FE using the 3FE ECU, I have the advantage of using a stand alone Wolf V500 which only require a Temp sensor from the thermostat and no worries on the vacuum system their is none.

G'day Matt,

I've really enjoyed this build - your dedication to the "2F" is extraordinary. This is the first thing I head for when I turn on the computer. I was wondering with the HP your motor is going to produce and your apparent love of flogging gearboxs like a red headed step child. Did you think about using an auto transmission?

Cheers,

Ben

I like to drive, auto's are for city driving :grinpimp:
I expect the rear tail shaft to be the current week point, I have already twisted 2 with my warm 2F, or the other is snapping the studs in the full floater rear, which usually twist and ruin the hub, though this I have not done since adding the 2 extra 8mm dowel pins. Though I did do this hmmmmm, but you can see the pins are all good as were all the sutds:whoops: So a new heavy duty tail shaft for the rear is on the cards.


Made this up from the broken stub axle above to easy replicating the 8mm holes in axles rather the having to do the hub and axle every time.

Thats mighty pretty, but we never got an 87 2F but would be perfect :crybaby: apart from the 2 holes are too big for the Temp sensors they suit the Vacuum thing that goes in one hole, the other I think is the same size but here on the earlier ones it just has a Allen cap grub screw blocking the hole.

We had the 3F by then, which is different again it has both inlet and outlet for the heater and no connection to the water pump. The 3FE is different again.

So I have ordered a new one of these

I can achieve the same using the 3FE bottom and late Aus 2F top and have an outlet for the Turbo feed.

Is the heater feed on the 2F of yours in or out? Just curious to weather the feed was still from the block or from the thermostat housing

It's interesting to know you can bolt any late 80 onwards 2F 4 bolt thermostat housing to a 3F or 3FE. The tops and bottoms are all interchangeable giving you a few various options.

After looking at Trollhole's set up I Picked up a 3F oil cooler today will give it a good clean and shot blast it before a coat of BLACK :D paint This will replace the stock oil filter. Had one on the originaly on the 3FE I bought but sold the block complete. But at only $80 at the wreckers I'm still in front:D

Also going to use the 3FE piping for the heater as this has a feed and return as well as the feed for the oil cooler. My 2F has just a single return pipe. This will bolt to the 3FE head as thats where it comes from originally. The mounting brackets of which their are 3 do not suit the 2F head as it only has holes for 2 bolts in it.

It's important to keep all the bits until you are finished it's the small things you never think you will use you always need.

A little progress today as we started to sort the wiring loom:eek:

Get some 4340 axles made up and use drive flanges. If you're having problems with the rear studs (which havnt been for me though I've broken two axles) upgrade to 80 series drive flanges which use 8mm studs and mod your hubs to suit. Dyna truck has nice heavy driveshaft with cruiser flanges on it...

Tks for the link,

Progress has slowed for the momment while we have guests from the USA here :D

The wiring is almost complete for the ECU though.
 
Ok the oil cooler is painted and ready, our American guests fly out on Thursday, I have booked Friday off work.
The issue with the thermostat housing is sorted
Time to get back in to it.
The water pump will be fitted, genuine Toyota, then I'll swap all the ancillaries over, alternator, air con pump, power steering pump, along with all the bracketry.
 
Well we packed our American guests off this morning, Great couple too:cheers:

So from the airport I hit the mechanics.

Water pump is on as is the the thermostat housing which is a hybrid of a 3F-E and a 2F:hillbilly:



The pipe work from the 3F-E is been used for the heater supply and return, now their is no feed from the back of the 3F-E head. Another reason to we needed to use a hybrid thermostat housing.





The 3F-E oil cooler has been added.



The two temp sensors for the ECU and in cab gauge.
