Rb25 Box Or Vlt Box, Need To Know Urgently. Pics Inside

[reeceo21]

Heya about to buy a car and it has me stumped what gearbox it is . It has tel tale signs of being a 25 box but then some of a rb20. the box is behind a 25det

- the bellhousing casting looks like 33 box

- speedo sensor looks like a mechanical one, but could of had a conversion

- And the most important piece of information is the way the slave cylinder bolts on. i was under the understanding that the 33's bolted on horizontally were as the 20 boxes were vertical ??

any help much appreciated i am ready to buy the car as im in sydney and need to know so feel free to msg me details on 0459302735

Wrong place to post but anyway,<br /><br />RB20 boxes have the slave mounted horizontally. <br />In RB25 boxes have the shifter mounted on a slanted angle whereas RB20 boxes the shifter is mounted flat. <br />If it tapers down to fairly thin then it's most likely a 20 box as 25 boxes are a bit larger.

25 boxes are quite literally twice the size of a 20 box (both turbo boxes that is). You cannot confuse them.

Well what do you think 25 box / vlt box or rb20 box ??

A vlt box has mx7 cast into the casing so look to see if it has that. But I think it's either a mf5 (vl n/a) or an rb20 box

OK. This is an RB25 turbo box.

This is an RB20 turbo box.

Upon looking at the photos (which i have seen before). It looks like a 25 box as stated as the gearbox looks pregnant were as the 20 one looks like its sucking its gut in. the slave is bolted horizontally so pretty much does a VLT box bolt like that ??

That is a 20 box, spedo sender is in the wrong spot to be a 25. On a 25 box the bottom of the bell housing doesn't curve up like the one in your photo, it sits flat.
