tRUkbOY Posted May 5, 2006 Share Posted May 5, 2006 (edited) 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?

CruiseLiner Posted May 6, 2006 Share Posted May 6, 2006 (edited) http://www.skylinesaustralia.com/forums/in...7502&hl=booster 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 Brad Edited May 6, 2006 by CruiseLiner Link to comment https://www.sau.com.au/forums/topic/65422-manual-conversion-checklist/page/11/#findComment-2144646 Share on other sites More sharing options...

CruiseLiner Posted May 6, 2006 Share Posted May 6, 2006 (edited) 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.

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.

CruiseLiner Posted May 8, 2006 Share Posted May 8, 2006 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 Link to comment https://www.sau.com.au/forums/topic/65422-manual-conversion-checklist/page/11/#findComment-2149867 Share on other sites More sharing options...

darrinspencer Posted May 9, 2006 Share Posted May 9, 2006 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 Posted May 9, 2006 Share Posted May 9, 2006 Gearbox makes no issues, but i would think the diff ratio needs to be changed.

CruiseLiner Posted May 9, 2006 Share Posted May 9, 2006 (edited) 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 Edited May 9, 2006 by CruiseLiner Link to comment https://www.sau.com.au/forums/topic/65422-manual-conversion-checklist/page/11/#findComment-2152863 Share on other sites More sharing options...
tRUkbOY Posted May 9, 2006 Share Posted May 9, 2006 (edited) 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?
