R154 Thrust washer upgrade?

[kwayzivietnamese]

Hi guys ...
after speaking to a knowledgeable toyota guru ... i just wanted to confirm a few details and get a few opinions

- is there a difference between the early supra r154 model gearboxes and the later model chaser jzx100 r154 gearboxes internally? in particular, the thrust washer?
- if there is no difference at all, is it worth while to replace the thrust washer with, what i heard is the usual route, a "landcruiser" item?
- what is the usual cost for such a job?

Cheers

Toyota EPC says 33348-35010 for JZZ30 R154 for example...

A cross reference gets a lot...and they are all the same...

'Martin Crawler' are meant to make an upgraded 1st gear thrust washer?

Hey Will, after speaking to d0ng when he had his box rebuilt I was of the impression that the earlier 154s had a different thrust washer from factory and that's why an update to the current part was considered an upgrade. Confirm/deny?

Matt,

Not sure, all I can say is that I see 8701-8801 MA70 and MZ20 on the list, and that's the earliest things that I can think of that came with R154?

But wouldnt the EPC be updated if new parts were assigned to older cars? looking at the list there you've obviously got a fairly recent version...

[wilbo666]

What they do in every other case I've seen is simply make a new part number, and then put "SUBS" with the new part number when you look up the old part number

Furry muff. Ive found a few sites referencing a Toyota made chromoly version of the old cast item, but no part numbers and I cant be bothered looking harder

oh man this is doing my head in ... decisions decisions .. what to do

[whatthe?]

Expensive bit of piece of mind.... I'd be trying to find out if the JZX100 came from factory with a chromoly washer before ripping it to bits

[kwayzivietnamese]

good idea Matt, hence the purpose of this thread/post

Can any1 please confirm whether or not the jzx100 gearbox came from factory with a chromoly washer?
