Try Rob @ castle autos in north baddesley 02380 740 242, he did mine at a reasonable price, hes not a specialist, but he does love jap cars, and knows his way around a 300 (in fact I bought mine from his yard in september), no guarentees, but worth an ask.....
an answer to this would be nice, as I have the same problem with my 92 auto, first time i boot it, it practically dies, boost stops, revs die, take foot off the gas and back on again, fine, it worrie me a bit.
saw you both within a couple of days, saw Andy in totton as you were heading out, i was heading in, live out on the otherside of totton, love having a car that is so noticeable, saw yours from a mile off, very nice!
yup, saw you just before christmas too, on m27 the day you went out to take pics in the forest.... i was going towards forest, you were heading back...
