Rb20det Gearbox Possibilities?

[PALADN]

Hey just about to get my r32 back from the turners with around 230rwkw at the wheels but because I use the car for drift I think that Ill need to put a new gearbox in.

what I want to know are there any other options other than an rb25 box? will a VL turbo box fit?

Before you comment I have done a search & couldnt find the right info

well an MX-7 is older, less smooth (less synchro) and they are the same price as an RB25 box

RB25 box or nothing IMO.

(and this info can be found )

[PALADN]

hey I found that it was ether the MX-7 box or the RB25 but was just woundering what other possibilities there are

[browny]

You can fit any gearbox if you have enough time and money....

I'd think RB25 is going to have the best combination of strength, cost & ease of conversion.

I've seen another guy convert a GTR box to RWD to save a few bucks, but the comment was something like if you can't do the fabrication work yourself then it's not worth it compared to the RB25 box

Well a GTR/RB25 box are same strength, and the same price.

Not worth the farting around even if yo were a bored individual IMO

[browny]

I thought the gtr box was generally a few hundred cheaper? Otherwise I tend to agree.

As a rough price how much is a 25 box??

Im in the same boat and just lookin at options.

[R31Nismoid]

i paid $1300, with yoke and a complete driveshaft. i CBF'd shopping around much

Box works a treat. A1 condition

normally a R box is $1200 anyhow i think

[Sheriff Wan]

Cheers,

Thanks for the info

use an old pintara box, my mate tried one on his rb25 powered r31 and it lasted a while. i think it was about a week......... lmao

[T04GTR]

yes a 25box is a good idea. the syncros a only a bit more efective but. if u smash the gears with button clutch it will pop.

a good one is the 34gtt box. beter syncro design and uses a bigger clutch.(250mm vs 240mm but pull type)

to fit it in the tunnel is a bit of an exercise. is ai origonaly an auto? they have a bigger tunel.

getting the corect drivline angle is very important.(getting the back of the box high enough)

not somthing that id do in my driveway, but much more thrashproof.

mx7 gearbox is the same size but has shit syncros and even worse ratios.

unless you want to run 3.4:1 diff ratio

[R31Nismoid]

the ratios arent to bad... its just... VL - 1987... R33 - 94-97ish gbox

you've got a LOT of time up your sleeve

[TurbostyleR]

or if you dont mind changing gearboxes leave it in there and if/when it does let go just get yourself a CA18DET gearbox and swap the bellhousing as the CA boxes go for 300 bucks or something and arent that brittle...

[PALADN]

What about a 300zx turbo box? anyone ever fitted one of them? or know much abouut them

[browny]

I thought these were about the same strength as the RB25 box but just more expensive and harder to find??

[GKTECH]

I already broke the box on my 32 (with an Rb25) and then found out I had an Rb20 box. Went shopping for an Rb25 box and the cheapest I could find was $1450.. Rb25 boxes are worth a few $$$

[PALADN]

thing is though will the 300zx box? sort of direct with minor mods because I can get them for about 500 each

[2LV8ETR]

I have been told the 300ZX box is exactly the same as the HCR32, except you'll need to change the bell housing.

I was told this when doing my conversion but I would want to be sure before purchasing if I was you.

I went with the R33 box.

[dangerous_daveo]

Yeah, I dont think a Z32 box will quite work without some stuffing about.

Just bite the bullet go the RB25 box.
