Guys, Does anyone know how much room there is, between the manifold and the underside of the bonnet in an SC400 ? Just wondering if there is much to play with ? Regards Stephen

SVC8, What do you mean " That's assuming that it's a straight passage; it's not " I am using a 1UZ-FE from a 92 Limited Soarer. I didn't measure it at the manifold to head connection which is wide and shallow, I measured it at the point where the bottom half ( Runner ) and top half ( Plenum...

Thank you Brett. Point taken, i have noticed a lot of my connections are very very brittle. Try to unplug them and the release pin snaps off, bugger ! Does anyone know if you can buy the individual plugs by themselves ??? Regards stephen

Well, I have let the car sit for a couple of days now and last night changed the crank angle sensor. No change, still running like a dog ! Did a diagnostic and this time it came up with " EFI NG ". Where to start ? Pulled all the injectros back out and checked they were all clean and in there...

Sideshow, I understand that this is your living, thats cool. As for the Colis, Leads, Dizzy Caps and Rotor Buttons. I have replaced the Dizzy Caps and Rotor Buttons about 1 month ago and they still look perfectly new, no build up. As for the Leads and Plugs, They have both done about...

Lambo, It sounds way out, but i haven't got around to checking the crank sensor yet. Going to check the crank sensor this arvo and try get to the knock sensors, hopefully without pulling the manifold off. Can you assist with any info on the effects that either of these sensors would cause...

Krayn, I can't see it being the coils, why ? Because since it started doing this i have replaced both the coils, the odds of getting a dud i would expect very very low. But thank you for the suggestion. It would seem Sideshow doesn't wish to assist with any of his knowledge unless he is...

Sideshow, It's a Soarer. Whilst there hasn't been a Scan tool used to test the diagnostics system, i have used the diagnostics via a jumper between pins and the car reads out on the dash and EMV screen. Diagnostic showed up nothing which is a real pain in the ASSSSSSSSS ! The knock sensor...

Sideshow, Thanks for the offer but i would rather try fix it myself. As for the suggestion of an air leak ??? I would imagine an air leak to be consistant ? I did say the motor wont idle at all, not even start unless the throttle is opened above half way. The timing is deffently way out I am...

Can anyone assist me, please ??? Has anyone had a speed sensor or knock sensor fail ? If so what were the effects ? One minute my car is running perfect and the next not even idleing. When i say not even idleing i mean, turns over if the throttle is open more than half way. Runs rough as...

Guys, Whilst the inlet runners entry to the heads are not a nice shape to work out section area. At the bolt up point of the runners and plenum the runners are round and a diameter of about 42mm was measured. With saying this, a port could see these out to around 50mm ? So the 4ag TB's would...

Quadcam Boat, You may be on the dot, I don't know ? I just saw it and thought it may be usefull ? I do not know how accurate it is ? I have owned a blown car before but it was all done for me, never had to really look into the calculations side of things. Regards Stephen

Can anyone remember ? Who the guy was that did the hardweld & regrind on the stock cams ? Regards Stephen

For all you FI freeks out there ! Hope this can help with your choice of BLOWER ! Found this on the Sprintex site, could be very usefull. Going by this, The Eaton M112 blower would be a little big. Maxing this blower would be using the engine @ say 7500rpm and giving ? 17psi Using this for...

Toranajud, From memroy i am sure i read somewhere that the sleeves in the 1UZ-FE are only 2mm thick. Sounds very thin but i'm sure thats what i read. If so i would imagine the 2UZ to be in the same vacinity, no chance of boring them. Do a search on the net becuase i remeber reading a very...

Zuffen, I expected they would fit but not 100% sure. I here peolpe say the ECU is elf learning but what does this exactly mean ? I don't know what injectors yours runs but mine don't seem to lean out at top end ? I can't think of why either, is the US spec unit have the same power figures ...

Staff, I am just curious, did you take the head ports out to the gasket lines ? Could you PM with some details on your job shown in this thread. Greatly appreciated Regards Stephen

High all, Is anyone able to assist me ? Is there a way of testing the oxygen sensors are working properly ? If so what is the procedure and figures ? Regards Stephen

Off the top of my head, i think my injectors are the smaller units. Mine is a *** spec Soarer 1UZ-FE. So if this is so, should the US spec units go straight in ? Would the ECU be able to make full use of the 251cc injectors potential ? Regards Stephen

Had the same problem as Zuffen. Looked at the price difference between OEM and aftermarket, thought the same as Peewee. Aftermarket for sure can't be that bad ? The length was ok, went on not bad. After a week of driving the odd little miss and when it came to changing the plugs. Huh, the...
