Chian, thanks for the response. I do appreciate your input, but I also get a little annoyed by some of your responses and arrogant tone which still carries on. I keep saying SAFC's are not THAT great, and even refer to them as dodgy.

I agree that there possibly is power loss bellow 10psi with extra advance. But 0-10psi is over pretty quickly when you stomp it so it may not be much of an issue to everyone. Once again, an emanage is going to be much better! I wish I had one over my SAFC, and so does anyone with an SAFC. But cars with a correctly setup and tuned SAFC still drive well, and go very hard.

You just seem to be VERY negative towards SAFC's, to the point where it seems you would never advocate their use to to the car "running like utter crap" or similar. And I think you said you can't use one to eliminate the fuel cut without loosing power. Which is 100% wrong. All you have to do is make sure the high load setting does not have any points with less than 14% (well 14% is what works on a 2JZ anyway).

If you set one up, do it up like I have told you by connecting the MAP sensor into the TPS input. That way your load points will be triggered by whatever boost level you want rather than throttle position. (it will obviously still be shown as throttle position on the SAFC)

Don't want any changes at 10psi and below? Just find what value 10psi is on the SAFC and leave that at 0% you won't have ignition changes below 10psi. I have been trying to tell you this for ages and you are yet to acknowledge it. A tip is the SAFC will take a bit of time to register the full rage of the MAP sensor, which may make it more difficult to tune. After a while, max manifold vacuum will be shown as 0% TPS signal, and max boost will be shown as 100% TPS signal. Just figure out where 10psi is by driving at 10psi and seeing what percentage comes up on the TPS reading. If you can't see that as some good info this will be the last post in which I try to share worthwhile info with you as it is becoming a little tedious.

Again, anyone running an SAFC and an FCD is going to have a pretty crap tune, considering anyone who would advocate such a system has a lack of understanding in the first place so it wouldn't be hard to improve on their tune.

Brendan, log of them maxing out a Denso 1.25bar (~18.2psi) map sensor (JDM 2JZ) at 3343rpm in 4th gear.
They come on a little later than CT12a's but in what feels like half the time. Give them some room (2 seconds in 4th) and they make 1.25bar :-)

Thanks Slip, but we would certainly need something better than an SAFC to control those on a 1JZ. We may even need something better already due to the large changes in VE caused by the cams.

Cihan, what do you mean by "come on later but half the time". You mean when the spool up very hard? Those are TD04's right? I think VF10's are a little different. I have not measured both, but my mate reckons he has and VF10's have a bigger turbine wheel. I might be able to get some measurements if anyone is interested.

Also, was this TD04 conversion inspired by my brothers car, or just a coincidence?

Dennis they're twin ball bearing CHRA's with 2560R compressor and turbine wheel's in the factory ct12a housings... Nothing like td04's.

Because they're ball bearing they come on boost later than factory but hit full boost within a shorter time frame.

Thanks for that Cihan :-) Would the CT12A compressor inlets and outlets start to become a major restriction with those cores?

They're sized accordingly mate, they would have matched the housing AR's to as close to garrett specs as possible to imitate actual 2560R's, essentially thats what they're transformed into with external packaging as per factory :-)

Manny and Shom have proven these turbo's are an excellent combination with the 1JZ once pre-turbo exhaust restrictions are taken care of.

Rob, can't wait to unleash the fury on those tyres hahaha boy are they gonna cop a workout

Dennis,
my TD04's setup was not a result of the inspiration from anyone as I didn't know there existed such a set up. It is just a coincidence. I've had the idea almost two years ago and I always like to play with an idea.
I'll find out tomorrow what these turbos can do on the dyno. Keep in mind that I'm still running stock ecu and injectors so boost has to be conservative.

Here's a couple of dyno graphs
As you can see Power rises pretty quickly between 2.5k rpm then drops just after 4k as AFR going to super rich. It looks like the timing was pulled significantly. Emanage can trim the fuel down but cannot alter the timing (was told by the tuner). I'm at a point whether to sell the car as is now or install the emanage and injectors and tune it then sell it as I need a four door to start a family :-) hehe....Can't put anymore money on the car.
Anyway, here they are. Any comments welcomed.

The emanage can definitely alter the timing.

What the emanage blue does best is alter timing.

I think what they meant was because Emanage is a piggy back and still rely on the factory ecu therefore factory ecu can pull timing off when it senses knocking (whether it's actually knocking or just some other noise).
I'm very tempted to put the emanage in since I have it here staring at me. The 440's are staring at me too hehehe......

Danny, I think you will need some boost to make the most of those turbos. :-) My car was slower at 10psi with the GT35 than it was with stockers. Most times you fit a bigger turbo/s the power gains will be shown at higher boost levels.

I think an Emangage would be a pretty good idea, put it in with the 440's and crank it up to 20psi :-) Just make sure you take it to someone that knows 1JZ's and Emanages. If your current tuner does not, don't be shy to find someone who does!

Without attacking the workshop, i'd like to point out for the sake of information correctness, if the chubby big dude is talking about engine management do yourself a favour and tune out.
--

Regarding the car, if its pulling timing like that with the factory tune there's something not quite right, its a lax tune and there really shouldn't be any problems running 13psi unless you've got a bad batch of fuel.

If theres a dead knock sensor and you want full control over everything with the emanage, there are simple ways to 'numb' the knock sensors. If all else fails, greddy sells an adaptor kit that deletes the knock sensors for $30.

Have to agree there, Danny - I don't know Chasers well, but if they really said what you quoted, then you need a different tuner. I'm told Paul Fiorentzhou is highly regarded, so from Cihan's comments above, you had somebody else there doing your tuning ?

The general idea is that unless its Motec, don't bother with Chasers, they are a lost cause.

Doesnt know anything if he says Emanage's cant do timing:-)

I would head elsewhere mate. That setup should push more than 195 at 13psi. If it were tuned correctly.

As I have said above, it's still running stock ecu and injectors, you can't tune the factory ecu or can you?

Stock Ecu, Stock injectors with an FCD and made 225rwkw with 15psi on stockies with stock dumps myself.

I will let you know how much boost the factory fuel setup will handle with a Blitz ecu in place:-) As i have some more mods since that dyno run also.
