Lr1 or AGP28?

[McGruffAWD]

I looking for a daily street/drag driven turbo. More Street then anything. I am looking for mid to low 12's. I see that some people have done this with the Big28. I like what i have heard from others about AGP so i plan on doing business with them either way. I talked to kevin at AGP about the lr1 about a week ago. He said if i went that way i would need a 3inch intake with a silicone reducer because the inlet is 2.75. Now with AGp28 i am sure is almost identical to FP's. So with all of the supporting mods running 650's S-AFC and a 190lph on a 98AWD with 18's( for shits a giggles, at track tho be running stock 17's) what do you guys think? O also where can i get a Silicone Reducer?

I am really leaning toward the Lr1..i hear it spools like a BIG16 but has the power of a 20g. I plan on doing the 1 shot turbo deal. 1 turbo to get me to my goal and thats it. So what should i do guys? I wish they had more info on the Lr1 but i guess i will have to wait for that. Thank in advance.

Noone has the info on the L1R but kevin and ben.

You can buy a silicon reducer from RRE or any Home Depot Motorsports.

It will be easier to run to your goal with a L1R. A big28 can get you there but it will be alot of fine tuning pulling every ounce of power out of the turbo. A L1R will give you a little for breating room to hit a low 12.

thanks for that fast response. Ya i think that for my goal the LR1 is the best bet. Another quick questions..will my stock internal be okay with this? I dont plan on running boost any higher then 20psi. But then again if i need to i will rebuild -) just something else to do.

 

[L2RTSiAWD]

I have the internal on my L2R and it holds 20psi fine.

Well... John is right, if you want to attain your goals than a L1R would be the correct choice. IMHO though, if you have the means, I'd do the L2R. Keep in mind, you're going to make more power at say 18 psi with the L2R than you will with the L1R, as the L2R will move air much more efficiently. The L2R, with the right tuning, will only begin to meet its potential running mid-low 12's thus adding to the life of the turbo (you won't have to push it as hard to reach your goal) You'll also have the option of upping the boost WHEN you get bitten by the boost bug. Its addictive.... well.... from what I hear Plus you're still looking at the same mods it'll take to supprt the L1R... FMIC, injectors, S-AFC, fuel pump, etc. And well... if spool is a big issue than my arguments are somewhat negated, but I don't think the L2R's spool is even close to being outside what I consider what a streetable turbo's should be.
Just some food for thought.

20psi by 4k is pretty streetable to me. If you were going with an "L" turbo I would also suggest the L2R over the L1R becasue of what bryan said about it having all the extra power there you will need. Like you said you were going with a "one shot deal".

 

[McGruffAWD]

see thats my problem hehe. I want the spool and the power. I dont want to go power crazy on the thing but then again..The boost bug is always there to bite. I have a month or 2 to think about it before anything is layed in stone. O about the internal. I am sorry i ment to say Engine Internals. Connecting Rods..pistons..you know. Will they be okay for mid to low 12 sec pass's?

McGruffAWD,

Stock internals will be more than fine for a 12 second pass @ 22 psi. Infact some do it @ 25 psi and see near 11 second passes [speaking for personal experience]. So, go out and have fun when you decide what you want.

Later...

 

[L2RTSiAWD]

Ot you can be crazy like rob and run 27psi

 

[McGruffAWD]

thanks guys. I love this site.

Actually, if you ask me boost lag is a blessing in disguise. Personally, when i've just cruising to and from work, I don't want to be on the boost the entire time. Yeah, I know dual stage boost controllers work around this, but you've got to figure that the turbo will have to work harder to hit that boost (L1R vs. L2R). I usually take my rpm's to about 3,500 before I shift when I'm just going to school or work, but yeah, when you're putting some punk in his place you're going to go above 4,000 rpm's regardless of whether or not you're using a L1R or an L2R, only difference is that the L2R will deliver much more quality air than the L1R. Unless you're an avid auto crosser and feel the need to turn the wheel (hell, I think just pushing an L2R in a straight line would scare the crap out of me, let alone trying to manuever tight corners) than I'd do the L2R. Let me lay it out nice and neat.... all just my opinion though.
Pros of L2R: not on boost 24/7 as the lag will prevent big boost numbers in normal driving conditions. Moves much more air much more efficiently (you'll make more power at 18 psi w/ the L2R than the L1R at the same psi). One turbo/setup change. WHEN... and trust me, it is a case of when... you get bitten by the boost bug you're going to want more psi. Eventually you'll want more than what the L1R can put out efficiently, in which case you're looking at deinstalling the L1R, prolly trying to resell it at a much much lower price than what you paid, and then you'll have to reinstall a L2R and get your tuning done to make it run right. In the end, with the $$ you'll lose from reselling the L1R, you'll be saving yourself some $$ by just buying the L2R the first time.

Cons of L2R: more lag... only a con if you're planning on turning the wheel a lot in race conditions. Fixing all the parts you'll prolly break in the process of tuning this bad boy... this turbo makes a lot more power than your stock axles/tranny can handle. Getting used to a big turbo car right off the bat... as I've heard, big turbo cars are tricky to learn on... but wow, I'd give my left nut for this "con" as I'm sure it'd be so much fun the entire time.

Welp, thats about all I can think of.

Man, I cant believe this crap!!! The FPB28 went 11s. Its more than enough turbo. And its a PROVEN product from FP(The leader in turbo Technology.)

NTW, This is a joke to everyone. HAHA

I really would like to see the L1R. My L2R spools quicker than my 20G did. Im actually thinking I would rather have an L3R at this point. But Im sure my L2R is gonna be just fine. Good luck on your choice
