i'd read up a bit about what's required to put an R230 diff in the 260,sounded a PITA to me unless you had lots of skill/time/money(pick one) especially when you have an R200 already installed(is it uni or CV halfshafts?) not sure about the R230 VLSD but the R200 VLSD is not very strong as far as the LSD goes,the viscous coupling won't cope with anything over moderate HP before going open centre,and it's not rebuildable the quaife is the way i'd go,lifetime,unconditional warranty and the advantage of the torque biasing system that for the street means no chattering/chirping around tight corners or carparks,no diff steering on deceleration,no adjustments to maintain full LSD just fit and forget it's the warranty that sold me on the quaife this is just my opinion for what it's worth let us know what you end up with

thanks for the input guys anyone hazard a guess at the spool up characteristics revs wise? how much quicker to boost would for example be a gt35r?

sandwhiched a (bolted a plate through either side)mounts on the trans tunnel then mounted the gbox plate mount across the bottom of them rb26 head/manifold flows well and has seperate throttle bodies.....nice....rb25 can still make big power,use the NA one to avoid the VVT crap,you can also fit better cams in it ali spacer between the chassis and front crossmember gives more room (depth)in the engine bay....you won't need it with the rb25/26 head

g'day rob i've got an rb30et in my 240z with std inlet manifold/throttle body ie crossover pipe goes over rocker cover,i got it to fit by spacing the body off the front suspension by about 10mm so you shouldn't have any difficulty with the rb26 twincam head as it won't need the crossover mounts the same for 240 and 260's you'll need to cut the "ears" out of the trans tunnel which form the original mounts to clear the jatco keep us posted paul

bugger!!!

hi guys a friend of mine fabricated a set of mounts for me 4 years ago....before the aussie mounts were available he originally used the 240/260 rubber mounts but said that the weight/hp of the rb30et was too much for the datsun rubber blocks,as well as the fact that they don't have a failsafe steel locking system incorporated in them he ended up using the donor engines ones which are the aussie vl commodore my friend has an engineering background and the mounts he made have worked well......anyone had problems with failure of the rubber mounts with the castlemaine kit might as well know before you use them cheers paul WA

is 350hp the limit of this tranny?? i hope not,otherwise it's back to the drawing board!

thanks guys but i really want the low rev spool,hence leaning towards the smaller turbo,agree tho that the gt35r would be the choice for racing

anyone got any suggestions as to which of these two gt30r variants would work best on an rb30et(fmic,bosch 044,wolf ems,standard manifolds,std sohc,2 1/2" mandrel exhaust) http://www.atpturbo.com/Merchant2/merchant...tegory_Code=GRT http://www.atpturbo.com/Merchant2/merchant...tegory_Code=GRT looking for good street performance,ie quick spool at low revs/gears with manageable traction....will be running a strengthened jatco 4 speed and 2800rpm hi stall which size turbine housing? int or ext wastegate? just curious how many revs later would a GT35R spool up,how would this effect street traction when boost comes on with the auto??....better/worse than one of the above?? thanks in advance

....you could also keep http://www.calaisturbo.com.au in mind for RB performance cheers paul

Will this turbo do what I want? hi guys looking for opinions as to the suitability of this turbo for my 302 240Z..... forged 8.5:1 pistons,eagle rods,edelbrock performer heads,roller cam/rockers,have performer intake with injectors as well as tuneable engine management system but am contemplating going staight propane instead(have twin GRA gas carbies and twin B2 converters) really want to minimize lag and keep boost threshold low(revs) so wonder if the turbine A/R is too large(1.11),was considering using half the tangential inlet(ie 1.11 divided by 2) and running a 50mm external wastegate through a muffler to atmosphere(hoping to keep back pressure/heat down in the valve/heads)would love to be able to switch the wastegated gas thru the second half of the tangential housing at higher revs like a variable turbine....anyone have any thoughts on this?? compressor is supposed to be good for 55lbs/min or roughly 550hp which is about all i'd want to put a 302 block thru feel free to give your opinion and experience oh and forgot to mention i plan running an auto and 2800rpm stall converter GT3782 .58A/R TS04 compressor cover with 4" inlet 59mm inducer 82mm Major 1.11A/R T4 turbine housing 66.5mm exducer 72.5mm Major Full floating oil cooled CHRA 3" V-band outlet thanks guys paul western australia

does this mean that the twin turbos will boost earlier(more responsive) in the rev range but run out of puff higher up the rpm scale? thanks to you all you guys who contributed paul

hi guys, i was considering twin turboing the 302 in my 240z but after getting hold of a couple or garrett BB turbos off the r33 nissan skyline and mocking up in the 240's engine bay it's amazing how it goes from empty to full....and that's without all the plumbing! anyhow i've already got the manifolding to run a single turbo upfront near the harmonic balancer but had a couple of questions .................. 1] what do you suggest as a suitable single turbo(motor has forged 8.5:1 pistons,edelbrock aluminium heads,eagle rods,roller cam/rockers) 2] is it worth the extra to get a twin ball bearing turbo? 3] how much slower is the boost likely to be with a single compared to twin turbos....i really want low rev torque not high rev/boost 4] internal or external wastegate? 5] would the single turbo be better than a centrifugal supercharger kit? any suggestions and advice welcome,especially from anyone who's been down this path regards paul

hi guys tried searching without success anyone fitted an AOD auto trans in their Z? wondering if the trans tunnel is big enough? also wondering how strong these transmissions are (HP) and how the ratios compare to a C4......really need the overdrive cheers paul

hi andy, was this an off the shelf item or custom made?? any chance of a few pics paul

thanks andy considered this but the manifold and distributor position pose some questions.............anyone done it?

anyone want to pitch in about the pro's and cons of the mx7(rb30 turbo vl commodore) box vs the one behind the rb25det....as they are easier/cheaper to get hold of in the land of oz i beleive the mx7 is very similar to the nissan patrol 4wd,and they can take a pounding slightly off topic but may help ash to decide which way to go paul

thanks guys looks like i've got some leads to follow/check over the weekend will post how i went next week
