I was reading through the thread and was going to weigh in anyway, though looks like you're very much on the page I am reading from - so I'll +1 with with a bit more anecdotal evidence to support it

The ATR28SS15 would be a perfect turbo for your application. I didn't look into some thing even smaller as it doesn't make that much of a difference in response but did loses quite a lot of power. I'

^ lol... maybe I'll use a 3" intake pipe and add in more bends.. that usually gets the suuuuuuuuuuuuuuuutuuututuutut going LOL. Anyhow, some real world facts to back up the results.. errbody likes ti

What kind of clutch are you running stao? Hope it holds up with the extra grip and big rpm launches. Mickey T's are the shit to. 275 is a big tire as well. I'm pretty sure the majority of gts-t skylines I've seen running them usually go a 255 on the strip. So the extra width should really help 

im running the 255 on 16" rim and put down 455rwhp perfect on the street, just grips n pulls like a gtr, but on normal tyres, it will spin 2nd/3rd pretty easy,they are even better on the strip.!

They corner fine, i used that size 7-8 yrs ago..they held up to upper 300rwkw okay, after that they didn't really have enough

sidewall to hook up, i drove from adelaide to melbourne and back on them, and on the way back the rain was treachorous

and they where still fine.

when i made upper 400rwkw..they only lasted 3 days though..they ended up deposited in the back guards/wheel well even from roll ons at 100km plus , no grip...

you should have got some falcon pursuit steel rims and fitted the 15's stao, much better with the big sidewall

cheers

Would you expect the result to be any different if you were using a Mitsubishio compressor cover? If so would you use a 20G or the 25G cover?

Got this tuned today. Big thanks to Status tuning as usual.

Just out of curiosity of what the 10cm L2 turbine can pump, We tried every thing to squeeze power out of and The maximum we've got it to was 385rwkws on 24psi. The car refused to make any more power after this.

At 22 psi it made 374rwkws so basically identical to SS2 at same boost level.

This goal of this turbocharger is to make more power then a T67 while having the same response to a 20G.

I've overlaid readings from:

Our brand new SLSS2 turbocharger
V
Latest SS2 turbocharger that has the identical compressor setup on slightly lower boost level.
V
The highest reading of a T67, Greddy manifold, externally gated.

All on Rb25det with stock cams.

The original plan was running small 16inch rims. and it turned out the majority of popular tires sizes is out of stock. My only options was the 235 or 275 in 17inches. Taking the 275 is bit of gamble and lucky enough I had a set of spacers. I will be switch to cross plys if this is not good enough.

By the way any one wish to swap mine with a Stock R33 GTR? I would like to do some thing with Rb26dett engines for a change.

Haven't tried SS2 wheel with Mitsubishi housings yet, but I don't see that been any problems. Might do up Trent's V8 turbos if he's not getting enough power.

sorry I meant 10seconds..380kw could get you there...11s at least... see how it launches I guess....just like my car, all.power with no support ..these Nissans hook up pretty well though, even on a stock rear end as long its not flogged out

Next mod should be a 2 way diff stao perhaps? Help it hook up? A few of my mates opted to put a gtr rear in there r33s for the extra strength as they kept doing drive shafts I think from memory. The clutch cops a hiding at them power levels and sticky track/tires. I reckon if it hooks up it'll run a 10.93 ;)

Haha he's not drifting the thing, don't need a diff that tightens under deceleration :P 1 way diff would be the go.

      Wheel refurb?

      The powder coating came in at $250 EACH. The TRX rims got a coat of clearcoat on the outside only.

      Keeping in mind that I am currently getting flat 10 L/100km on my RB25DET, which means >>500km/tank. I would test this car for vacuum leaks, check codes and AFM signal with NissDataScan as D says, check plugs, do a compression check while they are out.

      It is hard to be specific half way across the world...but it *seems* like it might have a minor issue. Is the idle stable and does it rev smoothly? I would not expect any pops out of what I am assuming is a standard ECU, standard tune, standard exhaust. You can use Nissan Data Scan to find out exactly what is happening when it runs, the cable/software is reasonably affordable if you are not planning on changing the ECU (which hopefully you are not with an NA skyline) BTW your mileage may not be that far off, these are heavy old tech cars, and being NA might mean you use a heavy foot to keep up with traffic....

      Hey guys! Y'all are the masters so figured I'd check in on a few items here. - My engine sounds ever-so-slightly more raspy than the other NA RB25s I've listened to. It's barely noticeable but definitely a slightly different sound. - When I back off the throttle at high RPM, I will sometimes get a pop out of the exhaust, assuming this can be diagnosed as misfire. Some history on the car: - Had an exhaust leak in auction sheet but was claimed to be fixed by seller (bought from USA importer).  - Car's coil packs and sparks were replaced when it was sold to me, but unsure on what the gap is and whether the coil packs are correct.  - A prior mechanic had misdiagnosed a pilot or throwout bearing sound as LSPI/detonation. Had played with timing a bit, pops/raspy sound of engine just got worse. Got timing reset. - Had failed emissions a few times. First time went in as is, failed. Second time, replaced cat, still failed, running rich as hell. Third time replaced o2 sensor, passed. Car still smells gassy though. - Timing belt and valve cover gasket also replaced.  - Gas mileage is... low. about 350-400K per tank.  Any idea if I'm having any serious issues here or does this all sound like normal old NA RB stuff and I'm fine to drive it with the pops/slightly raspy engine? If it'll help, I can get drop a video of the sound of the engine.
