OK long story but, looking for some input on turbo manifolds. Looking at this one>http://siteground207.com/~protegeg/product_info.php?cPath=160_253&products_id=1380
Putting my stock DP back on my MS3 (maybe keeping the RP? not sure yet if I'll go back to stock midpipe too) and a corksport CBE>http://siteground207.com/~protegeg/product_info.php?cPath=160_253&products_id=1061
Also looking for an AEM or MS3 CAI to replace my CP-E nano. I don't want to bore you with all the details but please some input on the turbo manifold would be great for those who have done the swap, impressions etc... Thanks. (dance)
 
And why'd you decide to go back to stock DP with aftermarket TP/CBE? I'm intrigued to hear because I just recently questioned the forum what people think of exhaust upgrades.
 
Considering how restricive the stock DP is and the gains from its replacement, I too wonder why go back?

And I'd like to see the dyno run on those advertized gains and what other mods were on that car. I don't see how that much extra power can be pushed through the stock DP and those two cats. Maybe the gains were on a car already modded with an aftermarket DP/RP, good intake, etc. and were on top of those gains?

PG, what say ye about how those numbers were reached?
 
Actually several reasons, I absolutely love the power from my turboxs stealth kit (DP/RP) set up. I'm still running the stock CBE. I also have a nano SRI/medieval TIP, forge bpv. (SU rear MM/solid shifter bushings, stand alone boost gauge, and a dashhawk for monitoring/datalogging.) I've had no CEL's or smoke from this mod and it performs really well, not to mention it sounds great under WOT. I'm sure I will miss it. Reason #1: I am racing in the nor/pac national divisional AutoX Solo II event in June. My car will be under scrutiny and right now I won't qualify for my class with this set-up. #2: I've had some occasional issues with boost cut/fuel cut as well, it's totally annoying and I'm not too crazy about any of the options to fix the problem, (map clamp or BCD and MBC.) I'm not going AP or SB any time soon either. #3: I know a couple of peeps (local) here in Northern CA. that recently have been ticketed for altering the cats on their cars and that's a big fine plus putting the car back to stock for a state referee inspection/smog test. We have some very strict laws here regarding cat removal tampering and the cops are enforcing it. I've had some bad luck with mods and my cars in the past too and am a bit nervous every time I drive. Having the power I have is great but not being able to use it for fear of getting stopped and given the once over is no fun. I'm going for a car that is basically street legal/stealth (that's why I'm looking to get an AEM or MS3 CAI (carb legal parts) to replace the Nano SRI and going for a turbo mani and the corksport CBE (mostly cause I like the sound of the CS CBE.) I don't think I will actually see 30+ HP from the mani (because after putting the stock DP back I will have that bottleneck again,) but it's a safe bet it will be better than stock and not a part that will be a potential target for the local laws. I might try the TXS RP as it is a part that I can swap in and out pretty easily, that's if it mates up O.K. with no leaking problems. I am a real junky for trying new parts and modding my cars and I also get bored pretty easy, (that's my sick nature, haha) so this is another project for me. I guess I can always go back to this current set-up too if I decide I don't like the new plan and I want to continue to live dangerously. (naughty) I'm always interested in others input so please keep the comments coming, thanks guys.... (encourage
