FJ20 turbo choice - over 500whp
Dose Pipe Sutututu replied to Gareth87's topic in Engines & Forced Induction
EFI Solutions aka Taarks have a great kit just for that. Better to have facts/data before making a decision. https://www.efisolutions.com.au/exhaust-pressure-sensor-pulse-damper-emap -
As soon as I come on boost that rear housing area, along with all the stuff connected to it will get pretty toasty and I'm not the type to race for a whole 10s or so 😘

RB25DE NEO into S30

Always, like how they talk in fly wheel horse power to sound like they're making big numbers. -

American junk, probably riddle with defects and will catch on fire - then they will lawyer up and blame you. -
RB25DE NEO into S30

Non-NEO RB25DET with VCT utilise hydraulic lifters, they're actually pretty good however don't like the tits revved of them as the hydraulic lifters can't keep up. To some extent, they're better as there are no shims to spit out and require pretty much no maintenance. In stock format, big cams and stock valve springs they are aids. Valve lift galore, with decent springs, cams they're a pretty good head. NEO RB25DET, although in theory "It's a RB26 head with VCT" in practice is a touch different as it's shim over bucket, not bucker over shim. Problem with this, is that if your clearances are shit, you'll shit out shims when you rev the tits out of it or bang the limiter more than Stacey's mum. -

This car will never run with this motor, by 2026 you'll be fitting Tesla motors to it lol -

Go even higher comp, throw in E85, why stop at 12? haha VCT, big comp, big cams, big braps in a classic zed would make and grown man's balls tingle. -

ASR Sumps do a AWD -> RWD conversion to fit a few different cars to clear any steering racks, etc. I once had an AWD RB25DET NEO in a R33 and ASR was able to supply a sump, pick up to suit the motor I hope you port it, stick massive cams in it, and make it brap -
g35-900 vs g35-1050 vs 6466
Dose Pipe Sutututu replied to Scratched Skyline's topic in Engines & Forced Induction
I don't have the data or facts, however if you're going to use a properly divided manifold and a divided rear turbine housing you might end up with a tiny bit better spool! I'll try dig up a comparison done on an EVO between open scroll and a T4 1.06 I came across years ago when I was researching the real world difference with open vs twins scroll. -
RB26 intake manifold on RB20

@Jordie Lewis amazing stuff mate, solid determination there! I suppose you're having quite a bit of fun too making it, maybe... just maybe you should make this into a kit/package and sell it once you're done to reward your time spent! -
g35-900 vs g35-1050 vs 6466
Dose Pipe Sutututu replied to Scratched Skyline's topic in Engines & Forced Induction
Proof right there! Great article here too: https://dsportmag.com/the-tech/twin-scroll-vs-single-scroll-turbo-test-the-great-divide/ Most car enthusiasts these days are too fixated on the final peak number they're producing, but often neglect to look at the low down, mid range, etc. Sure you're making 746kW (call it 1000hp so you sound cool quoting big numbers), but it's not going to be a fun car to drive, especially when you have like a 2k RPM range. It's kind of like a Honda, you need to rev the tits out of it to get anywhere. -
g35-900 vs g35-1050 vs 6466
Dose Pipe Sutututu replied to Scratched Skyline's topic in Engines & Forced Induction
I'm a firm believer that going twin scroll will make all the difference, even with a larger rear turbine housing. -
Now installed, fun times as the GKtech manual makes no mention of modifying the subframe brackets/brace plates. Needed to lop off the hump as the GKtech subframe bushes are flat and don't have an indent. Heaps of swearing later, it's in 🥳

g35-900 vs g35-1050 vs 6466
Dose Pipe Sutututu replied to Scratched Skyline's topic in Engines & Forced Induction
I feel that Garrett was pressured to release a new turbo to the market and rushed it out the door (big mistake). They now have a decent range of divided rear housings now. Also the American market seems to be dominated with V8s and you wouldn't really run a twinscroll setup on a V8 (or could you... 4 gates lol). lol... And you think every single bit of your Borg Warner turbo is China free? -
g35-900 vs g35-1050 vs 6466
Dose Pipe Sutututu replied to Scratched Skyline's topic in Engines & Forced Induction
It's because a couple of guys tried them with open scroll turbine housings, it didn't meet their expectations and it's scared off anyone else wanting to try them. In a proper twin scroll setup, with a decent sized divided rear turbine housing I dare say they would be very competitive. Now with the G40 range it's going to be a game changer, however GT-R boys seem to like replication of setups. -

They're fragile little cnuts but they do make the power and do perform! -

Yeah they seem to be very fragile, out of curiosity did you also run a Oil Pressure Regulator? I
