PRE-CONVERSION WORK ON A341E GEAR BOX: Tapping a hole in the gearbox case At this stage I should have tapped a hole in the centre of the gearbox shell, as outlined by Madmont in this thread: http://lextreme.com/forums/showthread.php?t=5906&page=2&highlight=output+rotor At the time I...

PRE-CONVERSION WORK ON A341E GEAR BOX: Cutting the output shaft A. Carefully measured output shaft on surf gearbox (68mm for this one) B. Carefully measured the same distance on the output shaft on the Lexus gearbox C. Cut output shaft of the Lexus gearbox so that it was the same...

PRE-CONVERSION WORK ON A341E GEAR BOX: Drilling/locating new speed sensor on transfer adapter housing A. Removed the speed sensor from the Lexus/Celsior Gearbox tail housing. It is short, fat and 14.9mm in diameter B. Removed the speed sensor from the Surf transfer adapter. It is long...

PRE-CONVERSION WORK ON A341E GEAR BOX Probably the most complicated part of the swap (complicated for me anyway) has been the adaptation of a transfer case to the 1uzfe auto gear box. This was achieved by getting a Toyota Surf auto box (the kind with the electric engaging manual shifting...

PRE-CONVERSION WORK ON VEHICLE: Steering Damper Bracket Issues For this type of swap the steering damper MUST be relocated as it slices into the oil sump if it is not moved. There is no way around it unless you want the engine to be sticking out of the bonnet by about half a foot. Luckily...

This is where the pre-conversion work on the actual engine ended, but the fun did not stop there. The steering, gearbox and transfer case still needed some major work done to them before the engine was anywhere near ready to be transplanted into the anxious donor patient.

PRE-CONVERSION WORK ON ENGINE: Temporary Air Box and Intake For the purposes of getting it in and out of the mechanics I made a temporary air box from the original V6 one to fit the new AFM. This was later replaced once the LPG mixer was installed, and is only really mentioned here for...

DOH!!!!! :banghead: :banghead: :banghead: :banghead: Thanxs Smitherz! I picked the wrong week to start sniffing glue....

Hey Peewee, now I am all confused. I just took a picture of the Celsior throttle and there appears to be THREE cables, two pulling right and one pulling left. I am pretty sure my motor did not come with trac control so what could the third one be? In the picture I have given them letters, A...

The drawing in post #150 looks like your truck's horoscope... :omfg:

PRE-CONVERSION WORK ON ENGINE: PCV Valve Had to install new PCV valve grommet in the valve cover as the old one was hard and it cracked too easily when I removed it from the valve cover for the powder coating. In Australia this is part number 90480–18001 and should be $6.95 from the Toyota...

PRE-CONVERSION WORK ON ENGINE: Plenum Vacuum Hoses Due to plenum reverse many of the air hoses had to be re routed. • The crank case vent hoses go from valve covers to a T-junction and then to a home made kitchen sink catch can. These then go into the plenum to comply with local emissions...

PRE-CONVERSION WORK ON ENGINE: Throttle and throttle cables The whole point of the plenum reverse was to swap the throttle from the drivers (right) side to the passengers (left) side so it would sit neatly in line with the snorkel and LPG setup. After some careful reading on various forums...

I guess it is easier to fool customers than educate them! A decent after market gauge is probably the only way to know for sure.

PRE- CONVERSION WORK ON ENGINE: Rear coolant crossover pipe mod As mentioned there is a coolant line that runs from the front of the engine near the water pump, through the ISC and the throttle then re-enters the cooling system on the rear crossover pipe. When the engine was installed this...

PRE-CONVERSION WORK ON ENGINE: ISC and Throttle Coolant Line Modification I deleted the coolant line that runs from the front of the engine through the throttle and then through the ISC. When I turned the plenum around 180 degrees part of the coolant inlet on the bottom of the ISC fouled...

PRE-CONVERSION WORK ON ENGINE: Idle Speed Controller (ISC) Inlet Hose The ISC (normally at the front of the plenum) is now at the rear of the plenum due to the plenum reverse. The ISC inlet hose was plumbed to the large nozzle under the throat of the throttle so that the air/LPgas mixture is...

Peewee: that is VERY interesting. Why would Toyota do this? It seems a bit irresponsible as many would assume that the red zone would equal about 100degC and not 110degC. I found an article on the Toyota Surf forum regarding this after reading your post. Will probably end up doing this at...

PRE-CONVERSION WORK ON ENGINE: Plenum Bolts and Studs Four studs (two long on one side and two short on the other) on the intake manifold were removed and swapped to the opposite side so that when the plenum was replaced on top it could be bolted down properly with no potential for air leaks...

PRE- CONVERSION WORK ON ENGINE: Plenum Reverse and Valve Covers I picked up the Powder Coated parts and replaced them on the engine, using new valve cover gaskets, spark plug gaskets, and intake manifold gaskets. Then went and bought various hoses needed due to the plenum reverse. Thankfully...
