why NOT to put a 1j in a hilux.

What sort of pump are you running for the water to air intercooler and how is it triggered? I can't remember if you said you have aftermarket management. I had to develop a nifty system to turn mine on and off (Liberty setup on Nissan Navara TD), it involves a hobb switch and a Bosch Timer relay. BTW I sold my Landcruiser yesterday

i'll have to let you know how we set it up tomorrow - off to do it now.. "the boffin" mumbled something about half-speed all the time, triggered to full speed manually..

im using two of the DC booster pumps.. 2 separe circuits. 1 goes

tank - pump - cooler - exchanger - tank
the other
tank - pump - exchanger - tank

oh, and shame about your cruiser, hope the new owner will love and care for it

Im just using a single Davies Craig booster pump as my piping nor my heat exchanger are very big. Well if you want to run my triggering system let me know. When the pressure hits 1psi it turns the pump on, while there is boost the pump remains on, then when there is no boost the pump is left on for your specified time interval by the adjustable relay 0 - 30 seconds. Of course while the timer is keeping the pump running and you get boost again it will reset the timer and override it.

interesting stuff.. at the moment it will be running full time.. might look at something like that later on...

Reference your Tacho. I ran an RA23 (Modeded for 6 cyl) tacho from the pink wire at the igniter.

cheers Chuck.

'Reference'?

we couldn't even get it to twitch.. and the adjustment on the back wasn't enough to adjust for a 6cyl anyway - Martin ran a resistor across some things to try and get it to work, but we are thinking he will have to make up a circuit with a flip-flop to get it to work.. and then put a adjustable resistor across the output to the actual needle.

- we managed to get the fans setup to run 2 speed, flat out they are VERY noisy, but move a hell of a lot of air, the pumps wont run at half speed, and pump a HELL of a lot of water, the returns into the tank were spurting hard enough to spray the other side of the tank, but are easilly drowned out by the fuel pump, and you can't even tell they are running once the engine is.

I can't believe I forgot to say how much I love your radiator overflow bottle It is better if you use a bottle with a sweet brand on it still though

[SL666]

it sits there nicely.. has done through all the testing

Have a look at the tacho booster circuit diagram floating around. It should work I suspect. Trigger it off the RPM output from the ignitor

we actually modded the tacho, it works now.. trans is playing silly buggers again though.. well not silly.. just trying to get it to do the right things at full throttle.. ive got pics of the mods we made to the tacho, i'll post them later..

[SL666]

You can see the extra resistor in parallel on the very left hand edge, and the variable resistery thingo on the top to 'shunt' the needle movement apparently, works.. we callibrated it with a multimeter measuring the Hz on the signal wire.

for reference the variable resistor thingie was this one http://www.jaycar.com.au/productView.asp?ID=RT4612
all the change happened at one end of its travel though.


The octopus of pumps and lines behind the tank.


tank before i bolted it down.


Finished product.

When we first took it for a hit with the pumps running etc, the water tank got pretty hot pretty quickly (guess at 40 deg) after a few spurts, we then decided that the exhaust blowing on to it was probably not doing wonders for it (we had'nt got around to putting on the droopy tip on it, but instead of cutting the 90deg off, we just tacked the whole thing on, with the car on the ground, the exhaust now exits pointing toward the ground and a bit toward the rear passenger wheel, just below the diff-tube level, its MUCH quieter at idle now.. MUCH.

oh and most importantly the water in the system is MUCH cooler, its removing a lot of heat from the intake though.. going to have to lag the hoses running through the engine bay, and wrap the pipe out of the cooler, into the TB.

And for all those that loved my overflow bottle.




A quick hit of matt black on the bottom (you can see it from the front) and bobs your dads brother. This came about because we couldn't find a suitable one, and when i went to put the grille on, it screwed up into a pre-existing hole, so we drilled the lid and cable-tied it to make sure it didn't swing around too much. (its in the wheel well right at the front)

[chris davey]

yeah that bottle looks even better than a genuine coke one now Looks like it does the job too.

BTW I have no idea what you are talking about with your tacho modifying

[SL666]

indeed

nice - i just tried to explain it the way it was explained to me..

Why to put a 1j in a hilux: for the look on the supra owner's face when you fricken whoosh (with squealing tires) past the kebab shop you were just in, after he was continually looking out the window to make sure you aren't touching his hekitk car. (that quite possibly had the mesh in the grille so you can't tell its aspirated).

The trans is right.

We pulled the codes on the ECU, got one for the knock sensor, had a look at the wire had been pulled off the plug at some point, fixed that, different car... it really must have been retarding the timing something fierce... boosts up earlier, and has more power.

[chris davey]

awesome! My car has been in limp mode for about 12 months now but that should be sorted soon
