When is redid the turbo I had it idle with just the 3 inch downpipe. It was a bit too loud for my liking. I don't know what dampening effect the rest of the piping will have. I used a "small" 63mm powerflow box with great success. Details on my downpipe thread.

JohanW

Klink vir my soos 'n torque converter probleem. In watter kondisie is/was die ATF?

JohanW

Remember its not just turbo lag, its torque converter slip too. I have a very free flowing exhaust on my AT. It exits in front of the rear wheel with a single 76mm powerflow box. It minimises turbo lag and other than a straight pipe I doubt you will get any more flowing. Also note that the d4d varia...

JohanW

The numbers are exactly what they say, L-1st gear, 2-2nd etc. Knocking the lever down to 3 means the auto box will only shift up to 3rd gear. You can shift down while driving, just don't shift down to 2nd while doing 100km/h obviously. In town shift down manualy until your revs/speed ratio is corre...

JohanW

One very very important note. The A340 auto has no torque converter lockup in 1st. If you are pulling a load up a really steep hill and unable to maintain enough speed in 2nd and above 2000-2200rpm (torque converter lockup velocity, also known as stall speed) you will rapidly heat the ATF due to tor...

JohanW

Ek dink jou probleem is 'n mate van driver error. Daai ratte oorsit net oor 1000rpm is wat jou brandstof eet. Ry bietjie die trok tussen 2 en 3000rpm, dus sit oor naby 3000rpm. As die turbo nie draai nie(onder 2000rpm) gebruik jy nie die 'voordeel' van die turbo nie. Ook kan dit jou EGT's te hoog l...

JohanW

Lekker man! Kan daai KZ nou ontslae raak van daardie extra lug? Die buig agter die turbo verander jou exhaust in 'n 1 duim nommer...

Blouaap, wees versigtig om temp senders en clusters te meng. Die temp senders het 'n spesifieke resistance characteristic curve. Elke sender en cluster kombinasie is gekalibreer. As jy die senders en clusters begin verander gooi jy daardie kalibrasie uit. So in kort, lexus temp sender by lexus clust...

JohanW

Marius, jy vra nou 'n klompie vra gelyk en probeer verduidelik terselfdertyd en dit maak dinge nogal deurmekaar. So jou vra is dus soos volg: 1. Kan cruise control beter brandstof verbruik lewer? 2. Kan my aftermarket cruise control vir my beter verbruik en krag gee? 3. Moet ek enigsins aan my enjin...

Consult the owners manual...If owners manual missing look in area near oil filter for a yellow/orange capped dipstick.
If oil filter area unknown look on the right side of engine towards the back with bonnet open.

JohanW

some good advice - thanx I will ask them to check the injectors and give feedback. They seem to be a weak point on those engines. The vehicle has auto transmission. There is a slight bump/clunk when accelerating and stopping, suspect the universals on the propshaft, Toyota will check that. The vehi...

JohanW

Thanks do you know if the box on the v6 is the same as the D4D box ? V6 has the A750F with 5 gears. D4D has the A340F with 4 gears. Pull the ATF dipstick. Does it smell bad, like bad fish, poo poo etc? What colour is the ATF? Red=recently changed and perfect Light reddish brown= still good but used...

JohanW

Find a friend with a techstream dongle and find out if they are still good. Alternatively book a test drive, drive vehicle to toyota dealership and have it scanned. All of the info you need is on the ECU. You just need to read it.

JohanW

I replaced the ATF on my 09 d4d auto a few weeks ago. ~195k km. Atf was brown and slightly burnt. Used 10L of Toyota ATF type iv. Shifts are noticeably crisper and torque converter seems to lock up earlier with less slip up to that point. Simply emptied the sump, refilled with 3L, undid the return l...

Klein Aus Vista is 'n besonderse lekker oorstaan plekkie vir jou verpligte uitstappie na Kolmanskop. Netjiese staan plekke met 'n boom en goeie toilet/stort geriewe. Billik geprys ook.

My air jack fits into a ammobox is a quarter of the weight of a highlift and not nearly as dangerous. Works on all vehicles with a exhaust

JohanW

Did the mod, got better turbo spool. But Oupa Stig is correct in saying that a fat exhaust and 4xlux downpipe is the way to go. A hammer and a small chisel got my box unrestricted.

JohanW

Short reply: This is normal since the hilux does not have a centre diff.

JohanW

Die VIGO modelle werk nie so lekker met 'n generic OBD2 reader nie. Dit is maar hit and miss. Ek het 'n bluetooth dongle wat op my KZ gewerk het maar glad nie op my '09 3.0 D4d nie en ook nie op my Pa se '07 D4d fortuner nie. Die beste is maar om te soek vir 'n Toyota TechStream dongle. Ek het myne ...

Guys I'll try see if I can get a vdo egt pyro at good prices. WHY? VDO make good sensors. Their thermistors are some of the most accurate on the market. But you pay for them.

Well guys, i'm not going to go ahead and print boards for the V2 of this monitor. My KZ was sold with the original prototype and is still going well.

Visited Bearing man today in lunch. Got a funny look when I asked for a 6103 bearing. Bought two 6301 bearings and the 17 x 52 x 21 bearing. Also couldn't find a 17 x 52 x 22 or NSK EPBD 17-29.

Seems a little bit of dyslexia crept into the original post

JohanW

Awesome, thanks! just to check.... was the two other bearings 6301 or 6103 ? The internet is pointing me towards 6301 for the idler pulley bearings.

Will post some pics when I do the install... Also going to do a complete ATF fluid replacement.

Was there 2 weeks back. Firstly, stick to the tracks. North of kubu its dry. Like driving on tar. Round kubu is also dry. South of kubu there are wet patches (under the surface) here and there about 2 meters off the track. You will see these areas clearly due to the number of deep ruts that have for...

Leaving on the 23rd June. Molopo, Kalahari rest camp, Drotsky, Guma, Ngepi, Kwando, Nakatwa, Kasane, Senyati, Elephant Sands, Planet Boabab, Kubu, Gabs, Kimberly, Orania and back home by the 18th July.

Also check the heat exchanger in the cab. Its a absolute female dog to replace. My heat exchanger on the KZ burst and emptied my radiator. Easy way is just to bypass it and connect the inlet and outlet pipes going through the firewall.

JohanW

Hi Guys, (might be a silly question) Is it difficult to replace the thermostat or can it be done at home? and I take it that all this does is makes the temp gauge more accurate?? Difficult is a relative term. The thermostat housing is in a awkward place. You need to undo 5 bolts/nuts and drain the ...

Cracked head or blown gasket. Been there done that same symptoms. Remove head. Send it in for pressure and ultrasonic testing. If head is fine refit with new original steel toyota head gasket. With new head bolts! Add a 74 deg thermostat. Once a KZ has overheated and started to lose power its almost...

On 30s my rpm was 2800 @ 120km/h. This I am sure of. I think it was 2500 @ 100km/h. On the 31s I cant give you a exact value since I have the colt 4m40 pump installed and I yet to calibrate the rpm reading properly from the pump to the cluster. Its currently reading 3100 rpm @ 120 on the 31s from th...

Haha, ja Marnus I also laughed a bit at myself and the situation. Going to use the screen in portrait mode. It did make mounting it a bit more difficult.

30x9.5R15 is 'n goeie grotte vir 'n kz. Ek het nou 90k km met 'n stel gery. As jy wil opgaan na 31x10.5R15 gaan jy krag inboet. Tensy jy 'n paar mods soos 'n fris intercooler en chip insit. Ek het nou op my nuwe stel op gegaan na 31.10.5R15 op die standaard 7JJ rims. Die voertuig ry beduidend sagter...

Meeste van die 4x4 kz's het die import diff. Ek het nog nie 'n 4x4 kz of 2.7 gesien met 'n gearmax diff nie. Sover my kennis strek het die 2x4 modelle met 'n gearmax diff gekom. Die Gearmax diff het 'n groot cover agter wat met boute reg rondom vasgebout word. Die import diff het nie 'n cover agter ...

Laat Francois daarna kyk. Daar is baie opsies in terme van draad herstel en oordoen. Een moontlikheid is om net met 'n tap weer die bestaande draad skoon te sny. As dit nie werk nie kan die gat grooter geboor word en 'n helicoil kry. Ek verkies om 'n insert in te sit eerder as 'n helicoil. My KZ se ...
