need to get a 100mm thick cooler blitz or apexi or something similiar, and thats pretty much all i need to get now :)

engine is at the machine shop at the moment and hoping to get block back within 3 weeks or so and the head is machined for the cams and porting is being done as we speak, the HKS t04Z turbo is ordered from japan and waiting on exact price from HKS :)

heres a few pics of the car at the moment and a test fit of the brembo r34 calipers and dba alloy rotors which luckily just fit behind my rims :D

and i been hiding all the headlight wiring harnesses and all the wires that run along between headlights and battery and headlights and air box on the other side, i took a few pics with the wiring gone and if u checkout your own stagea's they are full of wires usually :P

and heres the dba 328 mm rotor compared to the stock stagea front rotor :O

and ill show i few pics of before it had the motor taken out :)

ill update as i go in here rather than posting heaps of different threads :)]

cheers

I have said it once and I'll say it again....That thing is an absaloute beast! :D Cant wait to see what sought of power your getting on the dyno...

So when is it going to be on the road?

What did you have to do to convert the rear end to GTR?

Is it just a rear GTR diff and axle stubs? They all bolt in perfect etc? New driveshaft?

I mean, the power i will chase in the end, id like to at least be prepared as youve said stagea axles are tiny.. :D

hey alex its not as simple as first thought :)

the easy bit...

gtr diff housing and stagea housing r identical size, except stagea one has mounting points for attessa pumps and gtr one doesnt so i put the gtr diff internals in the stagea diff housing and therefore the same abs sensors were in also as the gtr ones r different, the rear diff plate on the gtr diff is alot bigger and shiny ally fins where as the stagea one is flat and black, gtr one bolts on ok but the fins hit on the rear cradle not allowing to pull hard up when bolting up, so we bent the end piece of the crossmember lip like 2-3mm and its clear by a few mm, which is fine and totally unnoticable :O

hubs and brakes fit str8 on with the change of two of the bushes, easy as :)

stagea tailshaft bolts str8 on as normal :)

axles r two different lengths (drivers side is longer than passenger side), which is something i didn't realise for a while, and i tried the gtr long axle on the short side and it was too short, and then i got a gts4 axle and tried the long side on the short side of my car and it fit perfect, so i got another gts4 one and thought it would fit (thinking they were the same length :D ) and it was wayyyyy short, like 70mm i think, so we cut up one of the gtr ends and welded on an extension piece on the the main bit that bolts onto the diff flange, and its lasted for abit of absolute thrashing and hard launches etc with 360rwhp but i dont know how its gonna take 600hp+ :lol:

time will tell :P

Ok,

So for realistic purposes, i may be better off to get some custom axles machined up by someone in just thicker diameter metal and stronger alloy?

Add a NISMO GT PRO LSD to the mix and that should mean overall improved strength i suppose...

Do you have any info on how the ATESSA would hold up with increased power? What problems can arise and what are the consiquences of the ATESSA going?

thanks gts evolution, i got em for a bargain price, thanks to a champ :)

and alex im not sure on the attessa, but its the same as the gtr one so i cant see any problems but thats what ive said about this whole conversion from rb25-26 etc etc and look its been on the road 3 weeks in 10 months :D

patience is the key B)

What did you use to paint the rear caliper?  Did you do it yourself, or is it a pro job?  I was always under the impression it wasn't a good idea to spray the inside near the piston.

Its going to be a damn fast volvo ;)

painted them at home with that anodizing paint, but u gotta buy an undercoat first so it sticks, its about $40 for the colour and the primer which is ok, it looks awesome for a spray can job :)

theres a thread in the tutorial section which explains details about the paint and how to do it etc :)

heres the link... http://www.skylinesaustralia.com/forums/in...+brake+calipers

i cant wait to drive it dont you worry :D

i love volvos ;)

cheers

  • 3 weeks later...

well finally some development in the build, and i picked up the freshly machined block yesterday and the head is machined for the 270/11.35mm lift cams but it still needs a freshen up and port and polish.

the day prior to that i picked up my HKS T04Z Turbo and its got through customs without and taxes haha, and it weighs a bloody tonne, lucky lucky i reckon :)

so with the block ready i just need to sort the head and then i need to get the JUN stroker kit instructions translated for torque specs and clearances etc.

assembly is not for away and im still searching for a 100mm thick jap intercooler, might get an ARE one, or a brand new blitz one if i have too.

ive got the n1 water pump and im wondering how that is with abit of street driving? because im going to be revving to over 10k so a stock water pump wont cut it?

heres a pic of the turbo and one with it next to a stock gtr turbo.

cheers

Considering you wont be needing your std turbine, want to give it to me at a bargain price so that i can get it rebuilt for my stagea?

I know its probably in good condition anyway, but im looking for a an any condition one to rebuild

The full build up thread is over here: http://www.skylinesaustralia.com/forums/in...showtopic=98086

That is so stupid, why the hell didnt they just unban StageZilla?

Politics, really gets in the way sometimes.

I wondered why the name change happened. What's the background to this for those of us obviously not in the know?
