Alternative option to the various tubular manifolds .. and stealthy somemore !

Running the Garret GT series turbos ..

 

Nice

 

Sweet, another alternative .

 

What's the price?

 

Wish there was more info posted... their first round of products didn't do so well.

 

quite agree though ..
The dyno graph is the same thru'out ..

which of the 1st round products are you talking about ??

But with the cast iron manifold, once you put the heat shield on .. you'd be hardpressed to tell the difference, unless you own an evo yourself

Good or bad .. the antilag holes are not drilled all the way through so for the USDM Evo's you don't need to plug up those holes .. my only question is why is it there in the first place if it serves no purpose

Unless your a drag queen, most of the people who installed them had less than stellar performance... unless you're quoting peak numbers that is. I am interested in that lower intercooler pipe though. Price isn't bad as compared to. I'd like a more gradual taper from the smaller piping to the larger, but for the price...

 

Actually .. I have not heard from anyone that has these fitted .. so far ..

It really depends on how you look at it ..

Evo's are great ROAD and TRACK cars .. when you upgrade turbos and tell people it's drivable .. I kinda doubt that .. there's always a tradeoff .. it's how much you want to trade off..

I can say the the GT25/28 hybrid series have only slightly worse spool than stock, yet makes only slightly more power than stock turbo (albeit at a more efficient level)
If and when you talk about the bigger turbos, you're totally right ..

Yes .. you'd be surprised how much difference a simple well designed pipe can do to the engine breathing

 

internal wastegates are gay

 

Brainstorm had this turbo kit on the their evo8. It was in Turbo Magazine and it made 407awhp on a DTS dyno at low boost with only exhaust and piggyback stock cams!!!

 

Of course they are... they are only good for 7 second quarter drag passes with a 4G63... you know, the fastest/quickest 4G63 on our soil.

 

Zeus, I have to disagree with you for the first time on this one. Internal WG can’t hold high boost applications (especially for one of the shelf). Yes on QM track its fine but when your EVO is on a 30 min track run and you get a 5 PSI spike because of the erratic boost spike (because of the IWG) that might damage your engine on the spot. Internal WG are great for low boost but once you go over 25 ~ 30 PSI an external one is a must. For example on race gas I hold 27 PSI all the way to 7600 RPM and it does not even taper down, can’t imagine an IWG doing that.

 

Mark (GT40) had this kit, not only did his manifold crack but the turbo lag was terrible. He sold it and got another setup with a SFP manifold and AGP turbo that cost around $2,000.

No offense, just because Shiv says that doesn't mean its true. Go look at the DSM road and drag/racers still using the stock 2G manifold with internally gated turbos.

 

You missed the point of a very bland statement... we are still in agreement (kind of) using your example...
