Is 07 STI better than previous years?

j2tham10 · 12-14-2006, 11:52 PM

Okay guys! i currently own a 05 STI. From what i have been reading on the power bragging section, the 07 STI are more faster when adding mods (without tune). Can you guys tell me what is in the 07 STI (performance) that 04-06 STI dont have???

The ECU is different, and is better at adapting to new mods better without a tune.

j2tham10 · 12-15-2006, 12:05 AM

is the 07 STI different then the limited (as performance)?

sperry7 · 12-15-2006, 12:10 AM

No one really knows what was changed yet, it's something pretty big though like pistons etc. It's not just the ECU.

what done to the head?

They revised them to improve cooling and eliminate the sodium-filled exhaust valves. I don't think anything else about the heads changed though.

j2tham10 · 12-15-2006, 12:28 AM

is it true the 07 STI has a VF43?

99subi · 12-15-2006, 12:29 AM

Yes it is true. The only diffrence from the vf39 is the wastegate size tho. Its made to prevent the boost creep issuse's

07 STI may have better performance capabilities

but with all that chrome?

...-1.

darknightohio · 12-15-2006, 12:51 AM

Wait for the 2008 model, then if you don't like the performance, looks or both just go for an 07 model.

ErasureWRX · 12-15-2006, 12:52 AM

but the 08 might not be more fasterer when adding modding?

EnterTheDragon · 12-15-2006, 01:09 AM

its going to take a while before modding for the 08 is even available...I'd wait, a real picture or some info has to show up soon

Ditto...

STi-JDM · 12-15-2006, 01:17 AM

07 got better tranny (IMO) because the gear ratio is longer...

007WRX · 12-15-2006, 01:35 AM

Lets talk about this new turbo...faster spooling or what?

Would it be better to use on a wrx?

Wiscon_Mark · 12-15-2006, 01:44 AM

No.

They only have 293 HP now

semaj · 12-15-2006, 01:44 AM

The '07 STi also lost the aluminum control arms, and has a smaller RSB than the '06 STi.

They have the same HP, the 293 is just the new SAE measurement.
