im getting my turbo-back exhaust, agp fmic, uicp/licp, HM intake install next month.

Should i order the forge wga and mbc? i think the stock ecu could control up to 26psi and thats good enough for me. im considering the forge wga because the car right now tapers down to 18 ( i think) spikes to 24. tuned by ivey.

Or should i get the new ATP downpipe with the 44m external wastegate ($800+)

what do you guys think? will the forge wga be more useful than a ATP dp with the external wastegate when it comes to tapering?

 

I was under the impression that an EWG downpipe would provide better boost control than just an upgraded WGA. Do atleast one of them though, either one will make a big difference in terms of being able to hold boost better to redline.

 

Maybe so but is the additional cost worth the end result? It nearly doubles the cost of a quality standard o2 elimnator downpipe (think ETS, AMS) I think I'll pass, unless there is staggering data to prove my common sense theory otherwise.

 

whether something is worth it or not is subjective. and i don't see how choosing a WGA over an EWG is common sense

 

Read exactly what I wrote and stop making things up. I never once made a comparison of a WGA to an EWG on the stock turbo. Call it whatever you want but I'm not paying a premium of $400-$500 for theoretical gains. A WGA has actually been proven over the stock unit by many tuners on this very forum time and time again. And for only $150 bucks BNIB, its a worthwhile investment.

 

^+1 Batmans right. WGA will improve ability to hold boost, but will need a tune after install. Its cheaper than the EWG you mention.

 

You said "unless there is staggering data to prove my common sense theory otherwise". So your "common sense theory" is that its not worth it because it nearly doubles the price of the o2 downpipe; i don't see how thats "common sense", especially since you don't know if there are/are not gains with the EWG.

TD66 - No one is arguing that a WGA will/will not provide gains, both Clark Kent and i know this. We're talking about whether or not a EWG would provide better gains on the stock turbo than a WGA would. And yes, the EWG is more expensive, but the question of the hour is "will it provide better results than a WGA?" thus making the higher price of an EWG setup "worth it".

 

Next thing you will be talking about is practice...not the game...but practice!
You state "better gains" and "better results than a WGA"! Are we talking about the game or practice! For a stock system with stock boost, EWG is overkill subjectively speaking (money) and objectively speaking (performance needs) and or results. Thus no welding of IWG, a WGA is not only functional, cheaper, most likely more suited to application, and purdy!

 

Sure...nit pick your way to clarity. There is no point in arguing with you because you haven't a clue what you're talking about. You've posted up in several threads recently talking that external wastegate on a stock turbo non-sense. Then you tried to throw your two pennies in DG Motors' thread. Pete and Charlie have been at this for a while so I don't think they need your help. I would be willing to say they've probably tuned more Evo Xs than any other shop in North America. Do you even have an Evo X? I didn't think so...

/discussion.

 

I see that you have now given up on discussion, and resorted to insults. You must have a lot of time on your hands to check out my recent posts for some sort of ammunition against me. Also, the Subaru community has been putting EWG's on their stock turbo setups for a long time, so there are advantages. It just comes down to whether or not its worth it for you. And owning an Evo X has absolutely nothing to do with a discussion about WGA's and EWG's.

 

Stay on topic and civil. Kthxbyi.
