Manual conversion checklist

[tRUkbOY]

So an R33 RB25DE 4WD pedal box won't bolt up then? They are a push-type box but I'm thinking it may be the way to go so I don't have to modify the firewall

The other thing I am wondering about is the Brake Booster. They are much bigger on the Stagea compared to the R33 Skyline unit. Does this need to be changed or is there enough room..................actually I might change it anyway, firm up the pedal a bit

Oh & has anyone got pics of the recess job on the firewall?

heres a thread i made ages ago on it, but i changed my username since i got banned

thats got some pics of my booster mounted (for the rb26 engine though) but i'd say the 25 would have more room than the 26 because of the 26's plenum which is mighty close. brake booster is very very very close but just enough room in the end

shows some of the pedal mountings further down the page as well.

good luck, and i think page 3 or 4 on this thread shows some pics from user "Argo"

hope it helps

Thanks Brad, appreciate it

looks not, but it is as far as i know.

[CruiseLiner]

pics dont seem to work for me.

also i dont see why u cant just use the non-booster one from a series 2 stagea and get the pedal box etc to match the master cylinder length (also the series 2 stagea)

dunno the difference in pedal feel but recessing the booster is a major job and as i've said i wouldnt attempt it with the motor in the car as its sooo tight around the area.

"also i dont see why u cant just use the non-booster one from a series 2 stagea and get the pedal box etc to match the master cylinder length (also the series 2 stagea)"

Thats the only other option Id go for. If the S2 pedals bolt into an S1

i seriously doubt the s2 pedal box will "bolt" in simply, the footbrake thing has some weird mounting spots and doesnt match the pedal box at all (going by my pedal box which is the gtr one i think). very simple job to bolt it in but, just weld one tab off one side of the box and make one of the original holes in the box abit bigger and it fits in almost perfectly using the factory bolts from the original footbrake setup.

the pics in that link i said shows u how i mounted the box but they are alittle crammed under the dash to get any decent distant shots.

Try this

talk about tight fit thats tighter than it is with the rb26 in mine.

it is recessed because the vacuum booster is pretty huge and it would stick out heaps more than those pics show

Meh they are on teh intarweb for all to see, I am just sorry I couldnt give you the answer to that question

Oh and I forgot if I had mentioned this but I do have genuine GTR pedals

[AlexCim]

the firewall looks "massaged" to me.

Maybe it was a bash bash job?

[darrinspencer]

Not sure if it has been covered before in this thread

Does the gearbox transfer case ratio matter if using a GTR gearbox for the conversion or should a GTS4 box be used?

Does the diff ratio need to be changed?

And also, has it been confirmed what clutch master cylinder a series 2 factory Type S uses

Vacumm or not?

[AlexCim]

Gearbox makes no issues, but i would think the diff ratio needs to be changed.

Factory S doesnt use a vac booooooooster

[CruiseLiner]

i dont get the questions properly darren, the diff ratios have nothing to do with the manual conversion, and the transfer case doesnt have its own ratio or anything, the gears in the box do though, but the 4.3 diff gears in the stock stageas should be alot better than the gtr 4.11 gears for getting moving and pulling the extra weight.

use a gtr 5 speed and tf case as they are nice and cheap these days at under $1k

hope it makes sense

Thats bizarre. I have a diff ratio of 4.0:1 in my Stagea

Can anyone tell me whether I can reuse the auto crossmember or do I need to get a manual one with my gearbox?

The question did not really make sense to me either once I wrote it

I was told by someone the other day there maybe issues with using the GTR gearbox

Anyway, I can a GTR R32 box for $500 and GTR R33 for $800 or a R32 GTS4 box

Might aswell get the R32 GTR box then

Thanks for the clear up

[GoldZilla]

R32 GTR gearbox for $500? I'd take two!

[tRUkbOY]

Strange. The other RS Four I have in the yard is also a 4.0.......................

Can anybody tell me about the crossmember?
