Yeldarb, I can see where you're coming from but people here really are IMHO just trying to help you, and warning you to be wary because of the awful experience that some other LOC members have had with their cars being messed up (not by ToyotaGT, of course).
You seem to have agreed a fixed price for the work, which sounds like an immense help if everything will all be done for one price, so if ToyotaGT hit unforseen problems then they'll have to sort it without charging you for it.
I've had some (minor) work carried out at ToyotaGT myself and they obviously know a great deal about the 3S-GTE engine itself, judging by all the other cars that they work on.
It'll be very interesting to follow the progress of this project. Please don't feel like people are criticising you or ToyotaGT here, at the end of the day I'm sure everyone will be extremely happy to see you get the result that you're looking for, after all more garages that do good work on Lexus can only be good for other members, providing more choice etc.
Please try and take the input on this thread as a positive thing, as other LOC members trying to look out for you and make sure you don't get your fingers burned (or worse) as has happened to others in the past.
I'm not very far away from ToyotaGT, and *if* you and they were happy with the idea, then I could pop down there while the work is in progress to take the odd picture to post up on the forums.
