The JZX100 (or the later models of it) use a 1JZ single turbo same as the late model Soarers (as the early ones use a twin setup). Both the late soarers and the Chaser also have VVTI. Essentially they are the same engine.

In terms of twin setups.. I'm assuming you're talking about Japan as theres barely any JZX100's in Australia... if you are yes it has been done many times over. I disagree with the comment that people buy single turbos because they are "cheaper". A turbo conversion is not a cheap exercise either way but consider why someone may buy two singles as opposed to a large single on a GTR. They'll have different characteristics in responsiveness, power, lag etc etc.

I wonder what happens to the engine management system if, say, one wants to convert a twin turbo setup on a supra to a single turbo setup. Does aft ECU like PowerFC can be used to control a twin turbo setup and/or single turbo interchangeably?

Maybe you're right, this will be extra $$$ involved changing the ECU when you converse twin to single turbo/vice versa?

On the other hand, if Toyota decides to abandon the twin turbo setup will that be due to production cost/meeting emission requirement in Japan?

I think JapLink in NSW already start importing JZX100 to aus, but hey, I dunno, check with them. HPI said their phone no is 02-97160857. Do they have a website btw?

I'm 99% sure that the JZX100 is already a single setup.

Anyway the Chaser has already been discontinued in Japan as of this year. I think all 2JZ and 1JZ engines are being discontinued.. some already are such as the JZA80 Supra, Mark 2 I believe has also been discontinued. Yes these engines are being discontinued for emissions. No idea about production cost.

Yes if you buy an aftermarket turbo you should buy a new ECU. Its not really as simple as just changing a setting on the handset I think. With different turbos you probably need to upgrade different things. For example in a GTR if you edn up getting a single conversion it is usually a pretty big turbo. This means upgading a lot more things than just the turbo.... such as intercooler, ECU, injectors and the whole fuel system like fuel pump an regulators etc, AFM's lots of things..... in order for all these things to be tuned properly aftermarket ECU is needed.

So what r they gonna use to replace 2JZGTEs then? Is Nissan also abandoning the RB engine soon? Looks like the death of the turbo era :D **sigh** I read that R35 skyline (or V35 callit whateva) would not likely to be turbocharged.... I wouldn't mine tho if they pack all these cars with V8, V10 or V12 & 400kw inside heheheh

I can't remember the replacement. But many of the toyota turbo models such as the Mark2, Laurel and Chaser have been merged into a few models that bridge the gap between the different kinds of cars...... none of the engines are turbo... YET!

I THINK the RB's have already been discontinued... the V35 at the moment has an atmo engine.... dunno if turbos are on the horizon...

    • The cross sectional area of a circular hole scales with the square of diameter. So a 2mm diameter hole is 4x the area of a 1mm hole. Not double. The 1.7mm hole is nearly 3x the area of a 1mm hole. You do not need restrictors at both ends of the oil supply line. If you have new, additional restrictors at the turbo end, that you did not have before, then you do not need a restrictor at the inlet end.
    • Hi all. Been a while but things are moving along. I just have something that I am wondering about. Since I will use OEM turbo oil pumbing, I got myself a new bolt, the one that goes into the engine block oil feed. As I recall (and see visually) this bolt comes restricted with I think a 1.7mm hole? Not quite sure but it was something around that size. The turbos have 1mm restrictor bolts installed, as necessary due to ball bearings and my higher oil pressures. Can I now just use that OEM bolt with the 1.7mm hole in for the engine block or will this actually be too much oil flow restriction and I have to drill it out first? In my head it would make sense for the bolt to be at least 2mm wide as both turbos take "1mm of oil flow". Do let me know if my logic is flawed here, I just want to make sure I don't kill my turbo bearings with too little oil. Don't know if I can trust the saying I read somewhere that ball bearing turbos essentially only need an oil mist
    • There are several aftermarket options available, from not-too-painful moneyhttps://justjap.com/collections/driveshafts-bearings/products/d-max-reinforced-replacement-rear-driveshaft-set-fits-nissan-s13-s14-s15-r32-r33-r34-c35 and  https://justjap.com/products/crank-motorsport-billet-rear-axles-fits-nissan-skyline-r33-gts-t-r34-gt-t?srsltid=AfmBOorQk4xkGUa98kO7v2ePLUiNt-HRrM2AwWNw9mbSIVE1ujBVwY__, all the way up to The Driveshaft Shop https://driveshaftshop.com/skyline-cv-axles/
    • Yeah based on old XRC5964S specs, it looks to be roughly GTX3576R sized? But this 5964S compressor will flow 90lb airflow somewhat similar to the compressors in both the GTX3584RS or G35-1050.. I fully expected the 0.64 rear A/R to choke up top - seems way too small from typical convention - but these are seemingly beneficial over the prior 0.82 results.. Be interesting to see if he comments on the EFR question in that thread - he mentioned in a prior video that BW EFR's were the "cats pajamas 10 years ago", but by the sounds of things all his kits have been using Xona for quite a while now.
    • Yeah it’s still got the oem manual gearbox and clutch, only kinda mods are a blow off valve, coil overs, and a aftermarket intercooler. Also had it for about 2 months now with a lovely midnight purple paint on it.
