AGP L2R Question

[GSXracer]

I went to AGP's website and looked at the info for the L2R, and they list a optional 34mm adjustable internal waste gate for it. Don't most larger turbos need external wastegates? And whats the difference between the two kinds of wastegates, and why is one better than the other?

 

[L2RTSiAWD]

I have the internal and get no creep. It's up to you if you want to spend the extra cash on an external setup. They offer it both ways to suit what you already have.

im torn between turbos here
FP green with INT gate
or L2R with INT gate
both have been known to run mid low 11's easy
which would be better for a street/strip car, mainly strip???

and fuel system. 660's or 720's??

well ive heard it said before so ill repeat it.. the L2R is a step above the Green.. it should spool faster, hold boost better, and pull harder then the green.. the L2R should be compared with the FP30 when FP decides to sell it to everyday customers

The L3R would be comparitive to the FP3065 that Pruven is currently using, both are using the same Garret GT compressor wheel rated at 65 or 64lb/min. The L2R is rated at 54lb/min while the Green, as stated on the old FP site is 49lb/min (why do I remember that?). DSMs tend to be able to make around 10hp per lb/min. I don't know what the size of the Red is, or what compressor it has, but I'm thinking it would fit right between the 54lb GT wheel and the 64lb somewhere based on the stated hp supported.

Side Note:
For DSMs you can just devide the hp supported by 10 and you should get the lb/min give or take, it's a good way to see if people are being honest with you. For instance if you know the turbo has a 50lb/min compressor wheel and they say it supports 700hp they are lieing to you.

All in all I don't think you can go wrong with any of the above turbos, pick one that suits your setup best (for example, do you already have an external? did you already spend big bucks on 02 eliminator that fits a mitsu turbine housing? etc). And remember, they all actually support more HP than most of us could make with them.

Is that 10 whp or at crank?

Crank hp

I use the L2R with internal gate. I started it out at 13psi, with no creep. I lioke this turbo better than any other I have seen or used. I would go further, but I dont want to get jumped by someone, hey Batman j/k.
The only thing I will say is that the L2R flows more air per minute than the Green. Im not sure about the L3R compared to the Red(I dont think you can get the specs on the Red.) And my L2R spools faster than any other turbo I have seen in its size range.

A guy on the A/T DSM list is testing a prototype L1R and says it spools at around 3700-3900. Didn't you say your L2R spooled faster than that? Any idea what the deal is with the L1R? I thought it was supposed to spool faster than the L2R.

I will nip this right now. There is not A/T DSM testing the L1R.

There might be an A/T DSM running an L1 conventional bushing, but definitely not an L1R.

 

[BatmanGSX]

Don't you love rumors like that? Where does this crap come from?

 

[doug]

Well, this particular crap came from a guy on the A/T DSM list who said he was testing an L1R.

[b00sted99-X]

so the L1R flows 42lb/min according to specs on the AGP -- that's comparable to what other turbos? What does the 20G flow? Big16G?

And I don't know if this can be answered by you AGP guys since testing is still underway but how much quicker do you expect the L1R to spool than the L2R?

 

[GSXracer]

Do I need a new exhaust manifold and any other parts in order for the L2R to be fitted onto a 2G? And does AGP sell just the turbo for 1400 or does it come with other parts?

 

[dyezak]

Bah...go full garret ballistic series if you are thinking about a l1-4r turbo. Just get the real thing (ie real garret ex housing) and be done with it. Just for the record, I'm lookin at a GT25BB right now (it's really not that big, flow wise) and I'm pressure testing the exhaust side. Let it be known that this turbo will spool 18psi at 2800rpm, but 390fwhp is about all I see this thing mustering...or 350whp. So that puts it comperable, or just a shy smaller than a 20g. The GT30BB (a-la L2R) should support 390-420whp, so it'll be a bit bigger than the green. Keep in mind I'm staring at these turbo's as I type this and have run the GT25BB (L1R equal) for quite a while. Anyone who wants an actual 500-550whp shouldn't look at anything less than a GT40BB or L4R. The 35 (or L3R) might be able to pull it off, but it wont be consistant. And yes, the spool on these turbo's is INSANE. Remember, this is more that a simple Ball Bearing upgrade, the turbine wheel is ceramic/titanium (if I remember right) and the compressor is aluminum/titanium (I think). At anyrate the wheels are lighter than anything else on the open market which helps the monster spool. But I still say ditch the crappy mitsu ex mani and turbine housing and go full garrett. Nuff said.

 

[doug]

So where would you get one of these turbos from?

 

[Black95GSX]

www.agpturbo.com

 

[doug]

OK, I'm a dumbass-- I didn't know you could get full Garretts from AGP . But still, why would you go through all the trouble of trying to get one of those to fit when you can just get one of their DSM turbos?

 

[Black95GSX]

I got my garrett prior to getting a bolt on garrett........

at the same time, I like how I can customize about everything possible on my turbo, easily -- not something you can do with a bolt on turbo. If i want to change my a/r.... It'll just be a short project.

 

[BatmanGSX]

Rob, I totally agree with you.

In the end I decided to go full Garrett as well. With all the mind changing and expierimentation I do it'll be great. Right now I'm starting off with TS04/O-trim. After researching Garretts for months (even before I decided to go full Garrett) I've decided that will be a great place to start.

And to anyone who wants to know, I have the supporting mods and a 2800lb stripped down car.

To also put another thing to rest... the person he's referring to that ran a 12.09 @ 119 is me... but I do not run an AGP bolt on turbo, I have a full garret T3/T4

Damn, are you sure you dont need a bigger turbo :laugh:

[GSX4LIFE]

Can you say LAAAAG-MUCH!:laugh: Yeah, I think Im going to be switching to a T112 pretty soon. BB of course so it will spool by 12,000rpm HAHA!:laugh:

 

[Ben K]

Batman,

Good choice. TS04/Otrim will work very well. Awesome compressor characteristics.

What manifold are you running?

 

[GSX4LIFE]

Hey Ben, I sent you some pics.
