iEvoego - f it's a standard auto box you're after, they're cheap as chips and you can often get them for next to nothing (I gave my one away to Rusty ages ago)

Big - that's great news that you'll get exactly what is required, it's just a bugger it's gonna take ages.

i see you found the air flow meter on TM. I recently split a loom off a motor for a guy down south and this has freed up an air flow if you miss out on that one - cheers

OK... here is the update we all been looking for..lol
Engine installed..made mounts,As you can see from the pics-it is sitting pretty well level and is way back in the engine bay,sitting about where I think it should giving plenty of clearence around the Lex and on top and under..I might have to address the sump when I give it full articulation but until then it is looking good..I have corrected the over correcting of CRS but as far as I'm concewrned they should have tere **** together and not guess..but as a whole it has worked out well.
There has been a little masaging of the firewall to give adeguate clearence of the cam/rocker covers..enough to put your hand in between and your fingures along side the chasis rails for the alternator and air con..Engine mounts have been added for reference.If I have done something not quite right let me know so I can fix it..(this is my first convertion)and I want it to look right and perform well..
Wiring and fuel/Exhaust to come..enjoy

Ok quick update..here are some pics of how things have been put back and I might say it is working out nicely..I have managewd to use all the original shroud,radiator(had bottom hose outlet shifted),power steering(just had to remove the lex outlet hose and i just plugged mine back in),oil cooler for hydrofan setup(had to plumb this in using bits and peices from other cars to get it to work) and currently wiring up this puppy..I have a EZ-wiring kit to convert from 24 to 12 and so far things are working out ok,i've been inspired by mycarhaspossessedme to do a nice and neat job and so far things are going well,the box that i've used is waterproof when the lid is on..i'm going to run a vent if it's going to be a issue....here's a few pics as I can't work out how to post in between each pic..lol enjoy..Oh and the mess in the cabin,I'm leaving this last..lol

On that note..how much are you after for it..? just i'm now trying to watch the fund vouchers as the wifeee is starting to get a bit pissed at how much..LOLmind you I think that would be the very last thing I need..LOL

Can ya let me kow..cheers and thanks..
Oh and I'm in the process of wiring the ecu..should I use the starter relay to start the fuel pump and ignitors etc..?I've got the provision for it just most of the colours in the diagram are different and tracing them is not much fun..LOL I've traced the temp and oil to the orange plug(cluster plug i think) and then I have to wire up the power to ecu,I think I got most of it sorted..(first time for everything eh woot..:sasmokin: )I hope I've not missed anything..anyways cheers

Howdy Big,
use the ecu to start the fuel pump/relay and the ignition switch (in on position) to power up the ignitors/injector 12V feed etc - often a good idea to hide a kill switch in the feed to the ignitors etc as well (good theft protection)
