05 gsr's turbo
 

I don't know where i read it, but i think it was a few months ago.. i read that the increase in tq/hp would be a result of a bigger turbo. is this true? i know something is different with it. Will it be easier to mod? also will the drivetrain changes give more whp or decrease whp.

thanks

p.s. i've done t3h search.

its a 10.5 exhaust housing in the new turbo.

Perhaps its a slight hp/tq increase due to the turbo while still adhearing to that overprotecting fuel/time map. The difference between our turbo and the MR (not sure if all 05's will get it?) is the turbine housing has a 10.5 cm^2 nozzle area...affectively a bigger A/R ratio.

Secondly, the wastgate has been altered to promote better exhaust flow. The turbo is just as easy to mod...you may still change the wheels ( I believe the 18G is the biggest wheel you may place in a TD05 compressor housing...maybe you have to step up to a TD06??) and you may change the turbine shaft to a Titanium one for less rotational mass.

This is an interesting question...will the ACD create more of a parasitic power drain than the standard drivetrain design we have?? Well....only dyno and straight line numbers will tell ;)

so thats why the 05 evo's msrp is higher than the 04s.. because of AYC and ACD and the bigger turbo...

btw..there is no AYC in any of the US Evo's. Unfortunatly....gas tank configuration prevents its installation back there(probably a few more reasons too) :)

but they took out the HIDs and the intercooler spray. theres also a front limited slip like the RS

ok, so i'm a n00b when it comes to the evo, but it seems to me if they changed the exhaust housing on the turbo, and gave it a better wastegate, then it seems as if the stock turbo should be able to make more whp with the same mods. does this sound right? will i have an easier time breaking 300whp with an 05 + mods?
