I am in a similar position or well maybe> I really hope that the OP is still around and getting notifications. If not then maybe a friendly mod could send a mail to see if they will respond. I have a Nissan MPV that has the re4r01a that was supposed to be bullet proof but it gave up the ghost during mapping. Comissioned a pro builder to rebuild the trans and it has lasted less than 10miles on the first build and not much better on the 2nd with major flair between changes. I know in the states they dont struggle to put the 500 TQ through a re4r01a but seems UK struggle. So looking for someone who has done the conversion and also if anyone on here knows the difference at the tail of the trans between turbo and non turbo. Re4r03a has a different sump shape with a bulge to accomadate the wider band. Tks and hear is hoping :-) BTW if anyone has an accelration run of an auto as a video would love to see it :-)
BTW anyone got a HKS ALC for sale :-)
