Have been speaking to Andrew Vibert from Central Victorian Auto Parts, he used to rally a JDM TE37 (which has unfortunately now been sold...), he's been rallying that car for a good 8 years now and was the Vic 2WD champion last year so knows a thing or two about rallying Corollas...

 

Anyways, we got to talking about gear ratios (since I'm looking for 4.3 gears), and the topic came up about the gearset from Palmside NZ, and also the gearsets that Albins has, and I mentioned that Rob was thinking of getting the Palmside gears... Anyways, here is some of the conversation (in lots of pieces):

 

Ivan albins has close ratio gearsets

for T50 boxes. He is in Ballarat. If he is going to use 4.77 gears then he

will need to think really carefully about gear ratios. To have a nice box

you really require 5.1 or lower.

 

Just out of interest I looked up the Palmside NZ T50 gearset, and

these are the ratios:

 

1st 2.63  2nd 1.89  3rd 1.34  4th 1.1 & 5th .86

 

Specs of gears available

As taken from Phil Bradshaws site.

 

Ivan actually made me a special set of gears when I ran a 4.875 diff.

1st-2.6, 2nd-1.84,3rd-1.384 (std) 4th &5th STD. It had a bit of a gap from

3rd to 4th.

After a couple of events I changed to a 5.125diff and changed the box to

1st- 2.44,2nd-1.66,3rd-1.24with std 4th &5th. It was great with no gaps.

Have a play with this calculator and you will see what I mean. A standard

TRD box  has a 2.34 1st and it is to tall even with a 5.1 diff

 

I forgot. If he wants to ring Ivan make sure he mentions me. Ivan did the

first one of these boxes for me many years ago.

 

He also gave me a gear calculator thingy (Excel spreadsheet) but I have nowhere to put it.

 

Anyway, thought it would be of interest (in particular to Rob)

the palmside gear set is actually a TRD one, i can get those cheaper as we are official TRD dealers, whereas palmside arnt.

 

id be keen for that exel spreadsheet if you can email it :dance:

oh see here for more info on the TRD one:

Mr Revhead: Price on the gearset? I'm getting rather interested too :dance: Haha, as if I could afford it... *dreams on*

well you gotta have goals....

 

33030-ae811 $2580nz

33030-ae851 $1770nz

just add freight :dance:

Umm, according to the Palmside page, they sell theirs for NZD2000 fitted? I'd imagine it would be a fair bit cheaper for just parts?

 

*edit* oh yeah, emailed you that gear calculator too

Edited November 16, 200421 yr by demuire

yup thats the cheap one, and its plus gst (12.5%) which makes it $2250.

 

 

cheers :dance:
