I am looking to get a 50 trim here very soon and have been reading up on the a bit but am looking for some advice.
I am looking at the AGP 50 trim turbo kits: Both the standard AGP 50 trim and the DBB 50 trim. I am also looking at the .48ar and the .63ar turbines.
Ok, I am running an E1 turbo now which spools pretty quick. If I hammer it at 3000 rpms it is at full spool almost immediately. Alittle slower than stock but not by much. My stock spooled around 2900 rpm, I would say this is maybe 200-300 rpm slower.
Anyway, I still want the 50 trim to spool fairly quickly but still have the potential to reach 500 whp if I decide I want to go that far. I am mainly looking for 400 whp on pump gas for daily driving. I also run meth injection.
Which setup would be the best for me to go with?
1. 50 trim DBB .63ar
2. 50 trim (journal bearing) .63ar
3. 50 trim DBB .48ar
4. 50 trim (journal bearing) .48ar
My friend is saying the 50 trim DBB .63ar. Which I am inclined to go with at the moment. I want it spooled NLT 4000 rpm. Preferrably between 3300-3800 rpm. I don't want to be waiting and waiting for the boost to come on towards redline.
My car would be run off of a S2 no toys PCM, S2 inj, walboro, FRL, and PTP FP rewire. Obviously if I run out of fuel with the boost I want to run I will keep it safe until I get some 650's or 750cc injectors. Also, I use the FM wga to control boost now with the E1 turbo. Would I need a MBC/EBC to control boost with the 50 trim or can the wastegates that come with them (turbonetics evolution) control boost like the FM wga does? Sorry, I have never used an external wastegate so that is the reason for the stupid question.
Thanks guys for the help.
In my sig is a link to my website where all my mods are located if you need to see what I am running to provide a good answer.
I am also waiting to hear back from John (PTP) before going ahead and buying the turbo kit to see what he has.
Well, speaking from personal experience.. I had a DBB 50 trim.. I would get full boost, like 25 pounds around 3k-3200.. It blew, so the cost to repair was retarded so I stepped down to a journal bearing. It definitely feels different, almost better.. The journal bearing hits A LOT harder than the DBB.. It's like the DBB goes building boost, building boost, building boost, gradually getting to full boost where as the journal bearing is like, little boost, little boost, ALL BOOST. I actually like the feeling better. In between shifts there's not really any added lag, it's just if you're starting out at a low RPM, and if you're racing you'll always be in your power band anyways. I would go with a journal bearing and save the money personally. I get full 25psi around 3500, it's a
.63 AR obvously.
As far as power, my car made 443/437 on pump gas, 50/50 meth on 25 psi... Built head, stock cams/IM/TB.. All supporting mods. The car is retarded.. It makes 3rd my bitch.. It's pretty crazy when you have to have DR's on for a 60 roll. I personally just use a MBC, I couldn't figure out the silly EBC thing. I did upgrade to a Tial 38mm WG because I was getting boost creep with the Turbonetics 35mm. I love the set up.. You'll hit your power goals easy.. But I will tell you, I feel like a need more top end.. So I couldn't imagine the .48.
ebay's your best bet. i scored my avcr bnib. the black edition for 380.
works like a charm, and is SUPER easy to use.
im joining the 50trim camp next week.
50trim/.48ar.
built tranny
built motor
built head (+1/+2mm valves, 5angle valve job, full race port, combustion chamber work)
crower s2 cams
SCT tuned
70mm boomba tb
70mm ported intake mani
full bolt ons. etc.
meth
i plan on taxing out a 430ish hp on pump/meth at a 22-23psi pump gas tune.

Based on the numbers I made with my mods I would say that you should hit that number easily. Keep us posted on the results. I am suprised to see you are going with the .48 though. With that built head shouldnt you be able to spool the .63 pretty early and then take advantage of its greater flow by revving higher?

what gas/psi did you do to get 42xhp/43xtq?
and thanks, hopefully i do hit 430. thatd be nice as hell. ive already hit 415hp on stock head/tb w/ a 47lb/.48 s3d last yr. so i should see some better #s.
i dont want to rev high any more. this car has become my daily driver (only use to drive it 2x a week and put 40mi on it a week) so i need to tone my car down. i wouldnt gain much, if anything if i switched out to a .63 and revved 200rpms higher.
my stock tranny DID NOT like shifting at 7k w/ my current turbo. w/ only 300miles of actually boosting, it killed it pretty quick..
w/ the built head/cams/70mm tb, power shouldnt drop off much, if any, by 630-6400rpms (where id shift). and im also fabbing a 44mm wastegate to mount on my agp mani...so that should help w/ holding boost/power at redline...and be original at the same time sorta.
I would really like to see any .63 cbb 50 trim get full boost at 3000. Not happening. On the street the .48 50 when well tuned is probably the best turbo aside from possibly an S256 but even that spools late.

Man you making me think it over, AGAIN...lol.
Ok with that said (and this is for anyone to answer), I'm going to be driving on the road 90% of the time with occasional racing, which setup should I go with? I thought a DBB would be a no brainer but is it really worth the extra money? I want good numbers for street driving and racing (430 and up), good drivability and I dont want to spool extra late. Oh and I won't be doing any internal work on the engine (maybe cams) so any suggestions?
