Default VF 52 legal for ESP

Is the VF52 legal to use on the 08 wrx in ESP? The rules say that you may swap the engine assembly, but the 08 engine assembly is the same as the 09 only the turbo is different. Has anyone talked to the rules committee on this subject?

nope, i believe the rurbo is not part of the engine assembly

such as in that if it doesn't say you can change the turbo, you can't.

Copied this from the rules:

4. Turbochargers and/or superchargers (“forced induction”)
may not be added, changed, or modified (this does not allow
ceramic coating of turbochargers). On vehicles originally
equipped with forced induction:

a) No hardware changes or alterations to turbocharger(s) or
supercharger(s), in size or number, are permitted. Turbochargers
or superchargers may be updated/backdated
only in conjunction with the accompanying complete
engine unit.


I think its kind of silly but it looks like you have to get the entire engine from an 09 even though its the same thing. Why anyone would protest the swap is beyond me too but who knows...

Turbo must be swapped with the engine.

This rule got changed this way because the 2nd gen DSM had a smaller turbo so the common thing was to use the 1st gen 16G. The pony cars didn't like that... so they got the rule changed.

If you can prove that the '09 and the '08 are the same exact engine (the DSM had internal changes between 1st/2nd gen) then you should be good to go, with the exception of the vin# on the block stating what year the engine was made. But remember, *everything* has to be the same.

Kind of expensive just to get the turbo.

Bingo. If there's a PN for the longblock assembly....it would have to match from 08-09 in order to change only the turbo. If the numbers are different, you'll have to change the longblock as well. (or the timing cover if that's where they put the number ).

I can tell you that I've been told (Chief of Compliance) part numbers are not the entire picture. All internals must be identical. Size/dimensions, etc.

You cannot prevent Subaru from putting a 2006-2008 head on your 2009 or visa-versa.

It becomes a 2009 assembly when you bolt it to the engine. Make sure you can prove it's the same assembly. There are some valve train component changes. It's alot of time at the parts counter to go through the assemblies 2006-2009 and figure out what is different.

Oh and the same will hold for BSP as that's where you'll probably be.

It was this very turbo that was the impetus for them motioning the movement of the 08-09's. They know it's potential. 300/375 awd, yum!

So are you saying that I have to compare all the part # of the 2008 to the 2009 to verify they are the same?

That would be the start, yes.

You can do it quickly by long block, short block, because they are the same. But you also need to know all other components.

I would also e-mail dgill@scca.com or bharmer@scca.com and get their thoughts on the matter.

Everything around the longblock is almost open in *SP so little trivia changes become mute.

Did you see the new fastrack. If you are running an 08 wrx in ESP, then I get moved to BSP and have to keep the 08 turbo. It will not be able to compete in BSP without the VF52. I do not understand why they think the 08 and 09 WRX are the same. I think it is a bad deal for 08-09 WRX.

They put the 08-10 WRX and STi on the same line.....so put the EJ257 in along with the turbo.

Nope. I'm looking forward to the 7-8 years down the road where I can *afford* to put an STi engine in a WRX. Or, an STi with the WRX tranny (higher 2nd gear).

I think you noticed item 26) in the fastrack. Pretty much nulifies my statements and leaves you with the TD04.

Like Storm and KC said, EJ257 and a 5sp.........

If you do wanna swap to a new turbo you'll need the 08 motor to go with it. Or, just the heads.
Like the ones I'm selling....

FYI 1st and 2nd gen dsm's did not come with a 16g. 1st gens have a 14b and the 2nd gen has a t25 ( which is extremely small and pretty much maxed out from the factory )
