Os Giken Rb 30 Kit

[Faid]

i have just received the parst for the os giken Rb30 kit bit still waiting on my stage 6 race head by AEBS california, but is it advisable to run a big twin in parralel (veilside GT 3542) or a single big T88-38gk trust turbo on this, i run a motec M 800 pro ECU with complete logging sensor array with EGT (x2), IAT (x2), Knock (x2), MAP (x2), wide band O2 (x2), launch, traction and air shifter control

The head that i am currently waiting for has extensive cooling mods that will enable me to tune up to abou 450 BHP/l. but i am currently aiming for 900-950 HP and a big shot nitorus to help me to 1100HP.. here are some of my new goodies that i plan on setting up, as there is a nissan pulsar that keeps on ginving me shivers down my spine:

MoTeC M800 ECU and complete logging sensor array with EGT (x2), IAT (x2), Knock (x2), MAP (x2), wide band O2 (x2), launch, traction and air shifter control

MoTeC Advanced Dash/Logger system

MoTeC CDI/8 channel ignition spark amplifier

MoTeC uprated high intensity ferrite coil packs (x6)

MoTeC complete sensor array and logging of over 50 parameters (shock travel, G's, all fluid temps and pressures in engine, gearbox, diffs, etc)

RB 30 engine by OS GIKEN

Modified to the fullest race head with custom intake and exhaust manifolds by AEBS

OS GIKEN 6spd sequential gearbox

OS GIKEN quad plate clutch

2* bosch fuel pumps

AEBS highflow fuel rail

NX direct port 200HP nitrous shot

hollinger custom drive shafts

Yokohama slicks

custom 1250cc injectors

Greddy racing BOV (recirculated) with 3 bar spring

APEX i radiator

AEBS Stage 6 head

tomei pro cam 280 IN @ 11.5mm lift

tomei pro cam 290 EX @ 11.5mm lift

titanium retainers

custom valvesprings for higher lift

mainly gen oversize valves

5 angle vavle hob

extensive porting and polishing

ARP bolts

Ill keep you guys informed if i have pondered over the turbo question with my tuner, but if you guys would help me out it would be great.

i have cloked with my GReddy hellcal gears at about 900-950 hp about 9.76, but in the last race my head stud bolts blew and the head acually put a dent in my hood, is was a complete failure, i am still trying to beat a nissan pulsar, that car is just develish, running about 900 HP on his car the carr clocks about 9.5 on a HKS kansai gear set with no syncros. raced im 3 times, still no luck, but for once and for all i want to be the top racer and im going big this time, so please advise on the turbo question

With a 3 Litre bottom end, a big single is okay, but with two twins and a 3 litre bottom end, this could be a monster.

A 3 litre Supra over here is making an easy 575 rwkw on twin TD05, so if you are looking for outright power, two turbos are better than one!

I like the idea of twin 3542s and you will still make over 1200ps without nos

[discopotato03]

If it was to be twins I suppose a pair of GT3567R's (technically should be called GT3584R's) from Full Race Motorsports could generate enough airflow for 1200+ Hp with large enough GT35 turbine housings . Geoff Raicer makes good stainless manifolds that don't fail on the Honda and Supra drag specials so I would talk to him .

Cheers A .

I was pondering that too, but in the past have been left with a bit of a blush after assuming that a thread was by a dreaming school kid - fortunately I hadn't said too much, as the guy turned out to be very much legit.

Something I find very interesting, is the NZ vs. Oz culture in going for turbo setups - in NZ, huge single turbos seem to be the preferred path whereas it seems you guys like twins.

Seeing as the OSGiken kits seem to make something which is very similar to a 2JZGTE, T04R.Com may have some useful information. Here is a table they have put together as a rule of thumb for power output potential and boost thresholds for different turbo setups on 2JZGTEs:

Mmmm GT47

School holiday posts seem to be a lot more nonsensical than this one generally!!

I would love to see a 3L with the twin 3542's!!! The Veilside car makes 1400hp using them on a 2.6L bottom end doesn't it??

[Beer Baron]

if you are serious then i would suggest you talk to veilside or HKS japan. get a big set of HKS 3540s. and enjoy over 1000hp.

why do you need a motec air shifter control with an OS sequential 6 speed though?

[SirRacer]

for outright power id also be inclined to go for one turbo as opposed to 2

when you look at some of the faster gtr's they all seem to be running single turbos. 2 that come to mind are reece mcgregors 7 second monster and the gms mag n turbo gtr thats running low 8's also on a single

when you consider they only run one wastegate, one exhaust etc it would be cheaper in the long run and looking at the times those cars produce, faster also

[Beer Baron]

that is quick but both HKS and veilside have runs 7s now with twins. i think for drag with big budget big twins are the way to go. and most of the 8 sec jap cars are on twins too. plus it's a GTR. it was meant for twins, it's part of what makes it a "GTR".

Ummm, when did Veilside do a 7??? And there are rumours HKS used a fairly sizeable NOS shot to help along their 7.67.... also, GTRs never were turbo at all until about 1989

I think Heat Treatments will be matching or bettering the 7.67 HKS apparently ran, probably worth noting they've already gone quicker than HKS could manage in Oz - with a dirty great big single and no NOS

[2rismo]

I find it incredible that someone would have made cam choice without knowing what turbo(s) to use.

[blk180]

On the twins and singles i seen in the new HPI that John Munro is ruuning a big single on his new set with methanol.

Dam lucky S.A will most likey be the frist in australia to get to see side by side 8 second pass's by GTRs

[thizzle]

what r34 ???...if i had all that shit i would take a few pics to save gettin flamed..

Edited April 24, 2006 by thizzle

[rb26s13]

with that sort of monstor setup maybe a T51r SPL they have the ability to make 800+hp.. if not i'd go something along the lines of twin t04z's or the vielside GT35/40's which is wat GTR700 runs from memory and well there running mid 8's?

but than again.. i'd love to see some pictures of this car.. otherwise we have very talented school kid? so im on thizzles side for now

also i'd like to see this pulsar.. aswell

[Leewah]

I saw Munro's new single setup late last year and the only way to describe it would be montereous!!!! It will be tops to see it run when it's completed.

Pete, which Supra are you talking about? Nige's Supra runs a twin TD06-20g setup, not TD05s.

well i cant give you a date, but i got that info from the owner of veilside himself, Yokomaku Hiranao. whilst i was standing next to his 32 GTR drag car i asked "what's the qucikest time now" and he replied 7.6X he said very close to HKS. he is running slicks now. his best time on street tyres was approx 1 sec slower than that = mid 8s. (8.6 according to veilside) unless of course he was bullshitting but i highly doubt that he would.

Wow... thats pretty big news if its true!! There are a lot of places around the place which claim that the top 3 GTRs are HKS, Heat Treatments, and Advance...

I wouldn't be surprised if they could knock off some huge time with slicks, the thing has insane power and not so much traction from vids I've seen.

maybe have a chat to CRD they built up RH9 which last i checked i am pretty sure it had twin highmount HKS 3540's was very nice

Checked it out on Saturday, it made 380awkw on 14psi easily on its initial tune....which BTW is more than GTR700 made....this thing will be an animal.
