as the tile says want over 400 bhp from a sti 8 but it must be reliable and able to work well in a very hot climate as the weather is already in the low 90 and its still winter any idea please let me know and who makes the items need

Try going for 350 BHP with a really big, efficient FMIC and a generously sized turbo.

200 BHP per litre and reliable in a hot climate is taking too much of a risk IMHO.

A 2.5 transplant may be an option as it would need lower boost to achieve 400 BHP, and it is only 33% over standard for this engine. If you got the right components you may be able to do it with only 1.0-1.1 bar.

As always there are pros and cons to each option.

Budget? Octane of fuel? Good ECU mappers on hand?

 

budget almost unlimited as the car is for a member of the royal family in Dubai and its a play thing but fuel will be min of 98.6 ron down side is lack of good mappers we do have cryo coolers for the intercoolers.
If you want email me please john

AJF: is there any chance you could keep us up to date on this project? It could be rather cool to see pics/specs of an Impreza developed regardless of cost.

If the budget really is almost unlimited, then why not ask an overseas mapper to travel and do the job?

 

If money is no object just buy a full blown WRC from Prodrive and to hell with daily driver

 

as i understand he does have a ex prodrive rally car but its undrivable on the roads and most of the rich over here already have evo 8 so he wants to be different as for pic and spec i will happliey post

please if anyone has done it or can highly recomemnd someone please contact me via email

Spec of the Litchfield T25 would be a good starting point, I suspect it probably would do 400 BHP with a big FMIC and a little more boost since the turbo is already an upgrade on the standard twin scroll item I believe.
