ralliart UK may have given the option to put ALS on the 400 (haven't seen any documentation of that other than your statement though).

yes there are bungs on the exhaust maifold to accept an ALS

this manifold is also used on Grp N rally cars which do use an ALS and also must use the same homologated manifold.

this still doesn't make the slight increase in high end performance worth the negative effect on the life of the turbo and manifold.

 

Unless your going to rally the car, seems like a real bad idea! And i hope you don't want to do this for the sound!

 

I don't know, but I love my USDM 8 w/ ssl the way it is. My brother wants to import a 3-5. So are the current models configured differently compared to the older evos? They all use a twin turbo 4g63; right? I could imagine a difference in the all-wheel drive systems, but how does an als system help you. Can't you use nos to spool up when you are suffering turbo lag. So far, I have not really experienced any lag. By the way, do you know where to look for old evos in California? I don't mind if it is a track car. We want to use it on the track.

 

Where I live you can get any evo you want, and from what I hear the IV isn't the best the AYC system in it is a bit whacky and can make the car unpredictable on the limit (just what I heard I don't know for certain).
All evos are single turbo.

 

Twin-scroll Turbo. There is only one in the EVO.

 

Anti lag is Like an after burner On a F-16 fighter jet. Fuel is sprayed directly into the exhaust manifold to keep the turbo spooled. I dont think it would do good in a street driven car.

 

It's the secondary air control solenoid valve system, it has mild antilag properties. Could've been left out due to emissions regulations or just trying to keep costs down.

 

UMMMMMMMMM!!!!!! isnt the 2STEP Raise and antilag function?! it sounds and LOOKS just like the anti lag that ive seen!

Are you talking about the so called "Mis-firing system"? The one that directly inject fuel and air into the turbo and keep the turbine spinning when you slow down the car at corners? Those systems would kill the turbo anywhere between 500-1000 miles of driving, no mentioning it's illegal to drive on the street and I think you can only buy pieces of the system and make it yourself...

Have you considered a Super Turbo for anti turbo lag?

 

mm... most of the gt5r owners i know in socal (the hardcore ones) are all antilag equipt... you just have a switch for it.


this is slightly misleading... a misfiring system is a method of tuning where fuel and spark are provided when the valves are open so that the fuel mixture is ignited in the exhaust manifold and turbine. there is no seperate injector for the turbo. and it's a tune for those moments right when you're off throttle.

you can certainly even run it without the spark. and also you need a way to provide o2 for the "extra" fuel to combust, which is where those "antilag bosses" come in from the euro and jdm manis, they take the bov air and route it in to pop the fuel that is injected off throttle.

it's not necessarily so that the exhaust system will be gone in some number of miles....

two step is similar to antilag but it's not the same cuz two step basically allows you to freerev at a "safe" rpm when the clutch is in. this extra fuel will pop and stuff to create spool that's more than freerev would produce. antilag does it whenever you're off throttle... so everytime you blow off basically you'll get some pop pop popopo pop and that will keep a good 15 psi spooled up for you.

i guess i should qualify myself about the reliablility... you'll find it very difficult to break the stock cast mani... the ones with the antilag bosses from uk will do just fine for making the setup. you can also get a throttle kicker instead (so it leaves the throttle open and you can get air into the mani for the "extra fuel") and run the stock usdm mani. so your mani is gonna be bulletproofed already.

the turbine housing should be just as rocksolid. but you'll fine that coating both is prolly a good idea (inside not outside).

the big problem is the turbine blades... if you have the tme blades on the 10.5 hotside they should last quite long indeed. so it can be run reliably.

 

interesting trinydex you sound like you know quite a bit about this, I must have a talk with you sometime.

 

feel free to pm anytime.
