Sorry bro i dont mean to look down or what but with that kind of mods i think is better to keep that 20v NA. because with piggy back for 20v turbo and that turbo, you wont got any satisfaction of power. Bear in mind in your mod list fuel pump and regulator is very important too. Mayb you can use 1j injectors as gZE injector is not the same type with 20v.
Well, if lets say piggy back i would say take 4AGZE, take out the charger and bolt the turbo. then that power is very very good with TD04 and Emanage. Trust me i have few friends here are using these setup and the results are good too.
Well bro, of coz NA is much much more fuel saving and easy to maintain. For me my 20v turbo is just my weekend car. Cant tahan lah it consume lots of fuel because its a standalone system. if piggy back of coz more fuel saving.
For the general questions, why mod a high compression turbo? Can't really answer you but the result is magnificent as you have 4-throttles with more valves turbo. But.... there is always a but.. to get less headache, pls go for 4agze and bolt turbo by throwing away the charger lah. If 20v turbo, you'll have to get a very good tuner and need to match the VVT opening and closing with a good Standalone. Bear in mind that Microtech is very very difficult to control 20v 4 throttle and unable to trigger VVT. Only Haltech can trigger it (e.g. ON and OFF). You need to off the VVT if the VVT is on all the way you HP on the Dyno graph will not go up. We cannot use VVT like VTEC function to trigger.
so please get ask the tuner what you wan before get the right management system.
I guess I have to disagree with u a little... I'm not sure what do u mean by high fuel consumption on a turbocharged standalone.
I am using a standalone on my turbocharged 1.6L system with FIC 750cc injectors(Yeah, I know it's oversized, but I got it at a dirt cheap price) on my daily drive. So far, no issue with fuel consumption. RM80 full tank RON 95, can go all up to 430KM cruising and slightly spirited driving. Which was better than my friend's 20V BT by stock.....
Standalone is Microtech LT10s with X4. It's the matter of how low your injection timing(ms) can go. Also, how low in terms of duty cycle your injector can maintain stability. Most of the injectors doesn't go well with <0.2% duty cycle.
So, here is the thing. Turbo charging/supercharging is just a method to pre-compress the air before it goes into the powerplant. But, at non boost effective RPM for entitled turbo, u can opt to increase the ignition timing slightly and tune it slightly lean. This is because low compression engine will tends to predetonate much much lesser on idle and cruise. I had mine 15.3-16.0:1 on idle and cruise. No drama.
On a high compression engine, the chances for it to detonate when lean and advanced ignition timing is higher on idle/cruise compare to low compression. So, u have to always stay stoic or slighly rich.
Unless if u're boosting the engine the moment u start the engine, i don't see why TC/SC will consume more fuel than NA.
I have to agree with troublesome maintenance of the engine. But if maintain well, it shouldn't be a problem.
yah, btw Haltech E6x cannot control VVT. Only E11 v2 can. Platinum S1000 or higher can.
Microtech LT16 can also.
Just my 2 cents.
