*POSTED THIS TWICE, NEED A QUICK ANSWER*

I want to get a Forge DV for my STi 8. Which one should I get. I'm not really interested in a whooshy one but there are sooo many to choose from on the site.

Has anyone with an STi 8 fitted one?

 

I fitted VTA Forge on my 1st STI8 and it didn`t `cause a problem at all. Haven`t had chance to sort one out for my new STI8, don`t think I will bother!

 

Why will you not bother. No good?

 

I have used one on a my01 WRX and they don't hold boost as well as the OEM valve, on general road use you probably would not notice but on track it really shows up. I had to mess around with ally' spacers provided by Forge to try to get it to hold boost. IMO don't bother.

Si.

 

Ok, thanks guys. Does this go for all the DV's. HKS etc?

 

I have only tried a Forge VTA so can not comment on the other makes. I have also read in I think the Drivetrain forum that VTA are not a good idea with cars fitted with a MAF sensor, you may want to try a search.

Si.

 

I dont want a whoosy one. Just a re-circullating DV

 

Why change the OEM one then?

 

Why upgrade then? There will be zero performance benefit changing from OEM to Forge recirculating...unless your OEM is leaking..which seems unlikely on a 3 month old car.

We used to change them on the Leon Cupra's as the Forge gave better performance over the OEM. I thought this may be the case with Subaru's

 

I used to have an Ibiza Cupra Turbo and changed to a Forge as the OEM kept failing, Seat just wanted to keep on replacing the failed OEM unit with another crap plastic DV. I must admit on the Ibiza it did make a big difference.

 

It's the same with some S3 model years. With Subaru though I don't think it's an issue as they rarely leak or fail.

Nice. Thanks for the Info.
