Hi Guys,
Thanks for all your replies so far.
Well, things are a little clearer than yesterday. But I'm still a bit confused.
What I need is something(s) that will :-
1) Remove the 1 bar boost limit,
2) Monitor and adjust the air flow and fuel mix to optimum levels through the rev range so I can safely boost at the higher pressure (probably 1.2 bar), gaining maximum performance from the big turbo without detonation,
3) Do all this without affecting the operation of the autobox.
Now the first thing that is apparent is I need bigger injectors, 440's from 2JZ, thats agreed on by everyone, and no problem with the sourcing or fitting.
Some say SAFC, some say E-Manage, some say both. What are the precise functions of each ? Do they both do the same job, work in parallel, or would they work against each other ? Remember this car is automatic (for the time being). Looking at my list above, which is more suited to my needs ? What kind of power gains have you guys got using the SAFC/E-Manage ? Anyone running a big single on a 1JZ ?
My other consideration is the tuning of these devices. What exactly is involved in proper installation ? Do I need a dyno ? From what I can gather, either of these devices can have a negative effect on performance and reliability if fitted/tuned incorrectly. Finding someone skilled enough here to do the set up for me could be a problem. Is there no such item which does all this automatically, ie. self learns ("plug and play") ?
Sorry for so many questions, it just seems the more I read the more complicated it becomes. Help !
Icarus, I see your car is a manual (nice), so I'm not sure the mods you've done would be compatible with my auto. The manual box is definately the way to go (for me, anyway), I feel like I lose so much control and driveability with the auto. I really appreciate the offer to bring something over for me, but I think I can get everything here at a reasonable price (with warranty). A new Apex SAFC II here works out at AUD$433. Enjoy your stay in Thailand !
BTW, yes, I've done the exhaust (2.5 stainless, no cats), and a huge HKS filter.
Cheers,
INTJ
