I have a MCS '04 and its in the middle east. the weather there is really hot about 40c (120F) the car is stock with no modifications ,,,I'm just planning to play with the engine little bit since my warranty is about to expire, if anyone knows what parts go well with the climate over there please post what he's got.

 

You might want to see the link on meth/water injection, especially in that climate.

I would think an intercooler would help you out, and running anything more than a 17% pulley might be a little taxing on the water pump in those conditions.

 

Cheap:
Run some Water Wetter
I heat range cooler plug might not hurt either. If you go with a 15% pulley I'd try 2 ranges cooler.


Not so cheap.
I really like the IC scoop I have but they're not easy to get. The M7 Ram is a nice unit.
Bigger IC may help. I prefer the GRS.
I'd wait for the DFIC to mature a little but it is worth looking at.
Coated headers

Like TampaMCS suggested try an Aquamist system. Very not cheap.

An induction kit will work. In your kind of heat you want a sealed one. JCW, Dinan, HDI, etc.

 

minimadness or moss oil cooler kit

 

oil cooler and c02 sprayer for your IC. I bet you could rig one with military parts for CHEAP! aka, ask around!

 

Run the highest octane you can get! That will def help especially if you get a reduction pulley (say a 15%). I ran 10 of thousands of miles with a 15% pulley in Phoenix, AZ (similar weather) without an issue and using the crappy 91 octane gas we have here. Higher octane will help prevent issues arising from higher Intake Air temps and higher compression (due to the higher boost from running a 15% pulley). Also get an air intake system, an exhaust, and an ECU tune dyno tuned specifically for your car!

 

just twincharge it
