Hey guys, i just wanted to know what the exact engine diffrences were between the EVO 8 US-spec vs the FQ340. Obviously the ECU is diffrent, but what else is there? and who makes those parts? Thanks

Which Evo VIII?

I understand the 2005 USDM is close to the UK/JDM MR engine.

Earlier models (03/04) were closer to older VIIIs in UK.

The MR FQ340 is based on the MR.

I thought the 2005 USDM VIII MR had a normal Evo VIII engine and not that of a JDM MR, as the US MR was only rated at 276bhp I believe

Isn't that the same bhp as the JDM spec (280ps) on which all UK spec Evos are based on?

The FQ340 adds as far as I can tell,

a. new drop in filter (RalliArt?)
b. hard piping kit for intercooler (HKS?)
c. HKS Super Dragger II exhaust
d. Unichip piggyback ECU?
e. other bits of cosmetic changes including the SatNav, leather seats

But the basic engine block should be the same.

The JDM spec GSR has a titanium turbo option, which I think is standard on the UK spec MR FQs.

US spec VIIIs only have the standard Inconel(?) turbine.

oh, i have an '04 evo8 rs, which is not the MR version. I think the turbo in my car is the 9.8cm outlet, not the 10.3? titanium one. One more question, do they change the clutch in the FQ340?? Thanks

they only decided the clutch was crap when they did the fq400....so the 340 still has the standard article.
