Rb26 Automatic Gearbox Transmission

[Tangles]

Hi all.

Currently have a rb26dett engine with rwd sump mated to rb30 manual tranmission.

My plans are to build it up, and drop it into my auto AWD C34 1997 Stagea

Receiving soon a r32 gtr 600hp ati harmonic balancer, greddy grex n1 SS camshafts, hks step-2 valve springs, hks oil pump, hks 87mm pistons, attkd conrods, acl race bearings

Will buy the rest of the required parts later "when it's time" such as greddy head gasket kit, n1 water pump, ati pulleys, arp main-exhaust-intake-head studs, greddy timing belt & idler/tensioner bearings

Im assuming I can swap the sumps over? rb25det awd stagea sump to rb26dett engine?

I will be keeping the car as automatic. Simple as that.

Should I build up the current stagea auto box?

Or by a VL/RB30 auto gearbox already pre-built.

What size stall converter should be used?

Thoughts on electronic auto trans controllers? The ecu's will be replaced by r32 GTR Power-fc

If I buy a pre-built box it wil most likely be using ford C4 or holden trimatic, so the fast tci would be required

If the stagea box can be built for 500hp then the tcm2000 powertrain will be used.

ford/gm * TCI Fast Trans Controller - http://www.tciauto.com/Products/Electronics/default.asp

nissan * Powertrain Control Solutions - TCM 2000 - http://www.powertraincontrolsolutions.com/transcontrol.php & http://www.destroked.com/pdfs/tcu_product2.pdf

what else is required? cheers for input

i have always been told that power fc can not be used with auto's!

thats why I will use a completely seperate automatic transmission controller such as the TCM-2000 from Powertrain (for nissan auto gearbox)

That PCS unit looks the goods, pity I can't use it with the neo tiptronic box in my stag

As for sumps, yes just use your stags sump.

Can a stag box take 500hp? dunno but mine is taking a beating with 1bar through the highflow and it's stock with no inputs from ECU (haltech). Someone will be able to build them up (knox or mvautos etc), I know there is a drag car here in WA using a 4wd auto box out of a stag so it can be done (pretty sure it even has a transbrake).

Moved to Transmission - given that is what the thread is about...

for what it's worth, apart from the diff ratio, stagea/gtr/gts4 sumps are identical.

i can't comment on the auto trans issue.... except to say if I did have an auto I would still run an after market ecu. my uneducated guess is the shift control impact is overstated

Bubba your not talking about the purple 32r drag car with graphics are you? That one is not a stagea box but is auto and still 4wd. I think its from a v8 cedric or something along those lines from memory.

The stagea sump is a gtr sump, they are identical from everything i can tell except the diff gear ratios.

Fantastic - so I can drop in a tomei gtr oil baffle kit.

thanks all.

yes I will be keeping awd, Im thinking I might as well build up the current autobox then - will speak to mike at mv autos

already have the power fc, engine, q45 afm's, 550cc siemen injectors, yellowjacket coilpacks, greddy n1 cams, gtr brake kit

for 3k I got hks 87mm pistons, attkd conrods, acl race bearings, hks oil pump, ati balancer, hks step-2 springs, apexi multichecker

for another grand will finish off with n1 water pump, service gasket kit, timing belt pulley kit, then build it up
