Manual conversion checklist

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

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.

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.

(hope you don't mind this Ska)

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

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

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?

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 :O

hope it makes sense :)

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

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

    • There is a LOT of stuff that can be done, it all depends on how much time and money you want to spend on doing in.  Not all ECUs will be able to do it, and the more control you need the more time and knowledge needs to be put into making it work.  If you're willing to spend the time and money and have the right hardware and skills involved there's a lot that can be done. 
    • I am impressed with all this level of adjustment. I didn't expect all this possibility
    • Correct.  In the case of the 500kw dyno plot I showed you the car actually runs two boost control solenoids for boost control and a 5psi wastegate spring.  It allows me to control how much boost pressure is applied to both sides of the wastegate valve at any point and fairly accurately control boost target as a result. I've tuned it so that it's able to target anywhere from 5psi to 25psi depending on what's needed.  The target tables I've set up in that car are Gear vs RPM, so every gear has potential for a different boost (and torque) curve.   First and second gear have quite low boost targets, third gear actually has different target boost all the way through the rpm range as it's a stock RB25 gearbox - the boost targets have been chosen to maintain a peak of 600nm (what the owner has set as the maximum torque he's happy with putting through the stock 3rd gear) but it carries that to the rev limiter.   The boost curve to achieve that is something of a ramp up, then hold, then ramp up again and the power curve looks more like a flat line haha.
