2G Run 4G63 NA with GSX Ecu and low boost turbocharger

[SJDSM]

Hi,

I looked for it before posting this topic.

Can I run a 4G63 NA converted with low boost turbocharger with GSX Ecu without mapping and without risk of breakage?
the turbo pressure is blocked at 0.4bars (6 psi).
Resistor box, 450cc fuel injectors, dumpvalve, wideband AFR installed...
Thank’s all!

The sensors are different and the wiring harness isn't plug-and-play. It's an entirely different engine from the 4G63 and the fuel maps wouldn't be accurate anyway.

I miss the Turbo Maf !

I know some peoples with NA 4G63 Converted with low pressure turbocharged ...

The compression ratios are different (over 9:1 vs 8.5:1 in the GSX) and the cams are likely different, so the volumetric efficiency of the engines will be different across all RPM, and the fuel/ignition maps therefore aren't going to be accurate. If you want to try to put a 4G63 engine with 4G63T electronics in your car with a hobbled turbo setup, it will run, but don't expect the tune to be accurate. It sounds like a non-OEM turbo setup is going to be used, which will further tamper with VE. If you want to take shortcuts by leaving it totally untuned, I'd wager that this will eventually backfire.

Ok thank you for your reply, so if I tune the Gsx Ecu it’s ok ?
Without tune it is ok but that’s will not be optimal and at my own risk to damage or the anything ?

You could install everything including the injectors, the injector resistor pack, turbo fuel rail with regulator, the turbo maf and turbo intercooler piping including the bov, and it should work ok, but it would be a little bit of work and parts gathering to get the needed parts,
