I will never listen to anyone telling me an engine is garbage unless they have many many MANY proof why it is and if they experienced why.
WHY? Simply bcuz everyone said my NEO RB25DET would be crushed with a big turbo, or "MASH UP" under abuse. Wrong wrong wrong wrong, its been 4 years and its NEVER destroyed, anyone can come see for themselves, and now thats its DRY TUNED, its just perfect at 11psi. Imagine that, 370RWHP @ 11PSI!!!!
Now onto the GDI 4G93T....Imagine what can be done IF i can get control of what i want? As the last post stated, with the mivec head, EVO 9 ECU AND HARNESS, which is what i was watching. It was either that, or a full standalone to make things easy, either AEM or ViPec EMS.
However, today i was really contemplating to just go with a complete evo5 front with rear end and convert the entire car 4wd and 4g63t. BUT, thats last resort.
Lets just mess with the GDI 4G93T and see whats possible.
First up, getting to keep the engine combustion area, cooler(Water Meth Kit).
Second, getting control of fuel, only way to add more fuel so far i see, is running a secondary pump system, with an injector controller, to control 4 separate injectors on the intake manifold. Just like a normal rail system, however, only double fuel injection while under higher boost.
Third, Ignition control, piggy back or standalone, but LETS GO PIGGY BACK and see how far we can take it. Research is being done on what to do.
Fourth, we flow more air, either raising boost on the tiny turbo or either an evo7, 8 or 9 turbo. Low boost would be raised to 10 psi IF it is TRUE that stock boost is about 6 psi. High boost, we can try about 14-15 psi. This is running on STOCK INTERNALS. If anything does blow, we go forged, build the block properly, and modify the head or just go mivec head as it MIGHT be like upgrading cams etc.
So, i CANT say these are bad engines, unless im proven wrong. So for now, we can just say, its an engine that has never really been tested to limits. I've seen a video where one has upgraded turbo, and probably 3-4 other things and it REALLY DOES PULL. But language is in some other type.
