After a great amount of time spent reading and going through this forum and N54tech I still didn't find a clear path for my goal.

Currently the car has FMIC, CP, DP and (Jb4 EWG OBDII) and I am opting for a turbo upgrade.

From what I gathered PS2 is the better option I think but it needs supporting mods to make the car reliable and can be used as a daily driver which is my plan to keep it this way. In terms of fueling unfortunately I'm bounded to use 93 only where I come from.

What I'm looking for is to get the maximum out of this T-upgrade using only 93 Oct. Any suggestions fellow 2Addicts??

If you live currently in KSA then you are limited to 95 RON not 93 AKI [95 RON =~= 91 AKI], the fuel in KSA is really shitty it's equivalent to around 89/89.5 AKI. Our fuel in Bahrain is slightly better but still shit.
Better off to invest in methanol injection system before going with the Turbo upgrade.
With your current mods and 100% meth you will make around 380 WHP++ on a dynojet.
If you went with the turbo stage 2 upgrade only you might make around 380-400 WHP with your fuel.

It seems to me that the methanol injection would be a better option in terms of reliability and going easy on the engine as well due to the reduced chance of knock and decreased intake temps.

Enzo just released a back-end flash stacked with jb4 for the stage 2 on 93 and is making 465whp. I've been running an e15 mix and it definitely adds some kick, hope to get it dynoed soon, probably around 480. That being said I will eventually look into either meth, tbi or pi for additional fueling but you can definitely hit ~450+/- on 93 and stock fuel system.

As for additional mods, be sure to get the upgraded diverter valve and inlet pipe from pure.

Thanks kfardan for the good info.

what about going in the direction of TBI will it make it better in terms fueling and reliability or should I just focus on the getting meth injection then opt for the turbo??

This project will cost me a pretty hefty sum and I don't care

Pure Turbo guy said you don't need to run higher octane fuel to get a reliable power bump because of the reduced exhaust back pressure.

Here is quote of what he said:

"It does make sense. The larger turbine wheel in the Stage 2 allows the engine to breathe much better (imagine the stock turbine is like breathing through a straw). This leads to lower exhaust back pressure, increased overall efficiency, and therefore less pre-ignition. So you can run more boost safely without needing so much octane to band-aid the situation. Hope that makes some sense."


what do you think??
