but that was not the question....

you are correct though...a street/drag/circuit GTR is great with 2x HKS 2530's

its the best all round turbo for the RB26...

this is only my opinion...

My opinion too.

Since he already has all the stuff for GTSS's, the 2530's was an easy answer.

:O cheers :)

the power the t04z is gonna make (potentially) is gonna go past the stock rods limits i would imagine (or didn you put betters ones in there Nick?)

Shouldnt be a problem if the rod bolts are replaced with something decent and your not revving the crap out of it. The achillies heel of the conrods isnt the rod itself but the bolts. Put a set of ARP bolts in, and you will be pretty hard pressed to bend them.

Nick what would you call your target rwhp or awkw etc ? as there might be other alternatives to your GT-SS HKS that will deliver better responce and drivable than something the size of a T04Z. I personally would only recommend a turbo that size if your chancing 440 to 450rwkw anything much under that i believe you can be better served with a different combo.

Nick...I'm with Tommy. I hav compared the response of my car to one with a T04z with a 0.81 housing, and the GTRS's spool up a little earlier and make similar power at the same boost level. I know they are different cars and there are a lot of variables, but the bottom line is whether or not it is worth the hassle and expense of going for a single and external gate.

The big Tomei lowmounted twins are another option that would be interesting, or even a pair of Apexi turbines.

Hope this doesn't offend any of the twin guys, seems to me that the single turbo cars have ran the times at the drags

Whats anyone on this forum done time wise with GT-RS?

hows 10.38 from a smaller set of 2530hks grab you, name me a t04z that got close to that and on GT-RS i only know of one guy run them hard on the strip i believe he ran a 10 with them (it's hard to judge a combo on 1/4 times when nones really push them hard down there but i believe in the near future there a gtr that could change all that in wa)

the other little fact i would like to bring to people attention is

2530 rated at 640hp

t04z rated at ?800hp

efficience and ease of install lives with the twins as a bolt on combo

What are the gtrs rated at?

hows 10.38 from a smaller set of 2530hks grab you, name me a t04z that got close to that

And on the flip side name me a GT-RS GTR in Australia thats got close to that aswell?

Im 99% sure we will find the times ran from TO4Z and GT-RS are pretty much the same

That wasnt run on pump fuel was it? The cars been comprehensively stripped too hasnt it? So it doesnt really have anything to do with what Blitz is after...

I currently have HKS 2530's on mine and they have been awesome turbos, but to make those numbers you really do have to flog the shit out of them. The T04Z will make the alot easier at the end of the day (albeit though, probably a bit laggier).

Pretty much spot on there ;)

doesnt have track suspension, tis a car build with drag in mind

1475kg...is not what i would call comprehensively stripped...its only marginally lighter than a stocker....and I weigh 105kg.

with Nick in his car the weights would almost match.

we ran 28psi to do 10.38 and 10.36....redline was 8250rpm...changing at 8000. I dont think i have even come close to "flogging the shit" out of them yet.

35psi and 9250 is flogging the shit out of them.

what makes the car so quick is the almost instant torque the car generates off the line due to the 2530's midrange. The 1.4-1.5 60' are testament to this, to half track we are around 0.2-0.3 slower than Mark's 9.5 sec beast. The second half of the track is where the t04z would be superior, as the 2530 lack the airflow to have the topend for 9sec passes without the use of NOS.

contrary to popular belief, this car was never built with drag racing in mind. Our set-up is typical of a Japanese weekend circuit car. We run all the ultra hard suspension, off the shelf HKS Hyperdamper, Tein caster rods, JIC top arms, Hicas lock etc.

Stace took it drag racing to have some fun....it just got a little out of hand when the car began to produce some incredible times and numbers....the bug bit.

But then there is the no air cond, no power steeting, no clutch fan...

we run power steering...A/C is only activated when switched (so pulley free spins on cars with a/c installed)...but yes we run thermo's

and what about all the added weight from the cage etc ffs every one thing I've removed I know I've near added 2 for andra or the new set up

Unlike the Japs...we have rules to follow here with our drag cars which means added kg's...:)

anyhow...back on topic...

so Nick.....decided what TO4Z housing you will get?? .81 seems like the go.

Edited by DiRTgarage

im sorry, do disrespect for twins, :) but single is the shit. so long as the manifold is corect. none of this 40mm odd massive thick runners. sorry hks,trust im not reving it to 12grand!!

in terms of exaust housings. .84 splitpulse is the most versitile.(garrett)

for a comparison my old motor (26 with stuff) made 326rwkw on 16 psi.

and it was a. tw41.

or t04e with o trim turbine 60trim 14blade compwheel

.84 split rear .7 front cover.

1.25"id runners about 18inces long give or take.

full boost at 3600 in second.

lowmounts would struggle get that without the bottle.

besides they are laggy but not. (builds boost from low rpm but not full boost till quite late)

anyway nick my advice would be to go for a drive in one equiped with what u are thinking of doing.

just so you can see. and perhaps come to a compromise. cheeres.

:lol: :lol: :lol:

2530 rated at 640hp

t04z rated at ?800hp

efficience and ease of install lives with the twins as a bolt on combo

umm. no ofence. 35psi boost and race fuel + a really good box. and somone who knows how to drive.

how longs a piece of string

    • Cheers. Skyline is back on the menu, can’t get rid of it. It’s like a child you don’t want, or herpes 
    • I got back to Japan in January and was keen to get back on track as quickly as possible. Europe is god-awful for track accessibility (by comparison), so I picked up a first-gen GT86 in December just to have something I could jump into right away. The Skyline came over in a container this time and landed in early January. It was a bit battered after Europe, though—I refused to do anything beyond essential upkeep while it was over there. The clutch master cylinder gave out, and so did the power steering. I didn’t even bother changing the oil; it was the same stuff that went in just before I left Japan the first time. Naughty. Power steering parts would’ve cost double with shipping and taxes, so knowing I’d be heading back to Japan, I just postponed it and powered through the arm workout. It took a solid three months to get the car back on the road. Registration was a nightmare this time around. There were a bunch of BS fees to navigate, and sourcing parts was a headache. I needed stock seats for shaken, mistakenly blew 34k JPY on some ENR34 seats—which, of course, didn’t fit—then ended up having the car’s technical sheet amended to register it as a two-seater with the Brides. Then there’s the GT86. Amazing car. Does everything I want it to do. Parts are cheap, easy to find, and I don’t care what anyone says—it’s super rewarding to drive. I’ve done a few basic mods: diff ratio, coilovers, discs, pads, seat, etc. It already had a new exhaust manifold and the 180kph limiter removed, so I assume it’s running some kind of map. I’ve just been thrashing it at the track non-stop—mostly Fuji Speedway now, since I need something with higher speed after all that autobahn time. The wheels on the R34 always pissed me off—too big, and it was a nightmare getting tires to fit properly under the arches. So I threw in the towel and bought something that fits better. Looks way cleaner too (at least to me)—less hotboy, less attention-seeking. Still an R34, though. Now for future plans. There are a few things still outstanding with the car. First up, the rear subframe needs an overhaul—that’s priority one. Next, I need to figure out an engine rebuild plan. No timeline yet, but I want to keep it economical—not cutting corners, just not throwing tens of thousands at a mechanic I can barely communicate with. And finally, paint. Plus a bit of tidying up here and there.  
    • Nope, needed to clearance under the bar a little with a heat gun, a 1/2" extension as the "clearancer", and big hammer, I was aware of this from the onset, they fit a 2.0 with this intake no problems, but, the 2.5 is around 15mm taller than a 2.0, so "clearancing" was required  It "just" touched when test fitting, now, I have about 10mm of clearance  You cannot see where it was done, and so far, there's no contact when giving it the beans Happy days
    • It's been a while since I've updated this thread. The last year (and some) has been very hectic. In the second-half of 2024 I took the R34 on a trip through Germany, Italy, France and Switzerland - it was f*cking great. I got a little annoyed with the attention the car was getting around Europe and really didn't drive it that much. I could barely work on the car since I was living in an inner-city apartment (with underground parking). During the trip, the car lost power steering in France - split hose - and I ended up driving around 4,000kms with no power steering.  There were a few Nurburgring trips here and there, but in total the R34 amassed just shy of 7,000kms on European roads. Long story short, I broke up with the reason I was transferred to Europe for and requested to be moved back to Japan. The E90, loved it. It was a sunk cost of around EUR 10,000 and I sold it to a friend for EUR 1,500 just to get rid of it quickly. Trust me, moving countries f*cking sucks and I could not be bothered to be as methodical as I was the first time around.
