turbo purchase, need suggestions

[Twizzle]

well im in the market for a new turbo, something to upgrade from my big16g. i will spend up to 800$ and i need it to fit my 2g manifold. whats the best turbo that spools before 4k rpm, that will be better than a big 16g, also, if needed, include the o2 housing too. i also think i want an internal gate.

 

[Kandy_GSX]

Take a look at the Agp RS series turbos.

 

[CowPimp]

The 20G is a pretty tried and true solution that will offer quite a bit more power than a Big16G. As well, I am pretty sure this turbo can be internally gated without too much trouble.

check out the Featured Product above AGPTurbo.com RS52 for $850 (internal wastegated)

yep agp rs turbos, or look at the pte gt3255 and 50 trim bolt on turbos, there realy nice also

That's what I was going to say also.

 

[Twizzle]

looks like we have a winner, also, do i need oil feed/return lines or can i use w/e i have now? i think i should get them but if i dont really need them, i wont.

 

[huggi]

the evoiii 16g is pretty cheap but all the additional costs add up

exhaust mani 200
o2 housing 200
install kit 200

whats the best bang for your buck, for 2g's that is?

 

[TSIfreek]

Yea I would say AGP 52 the biggest and the 49 will also work well if on a daily driver also PTE 50 trim also works nicely on the street and makes lots of power. The 50 trim can support 400+ HP and loves to rev. Makes full boost at around 3500 RPM. Its also named the king on pump gas. Has lots of potential with other internal engine mods like cams and head work. It mounts the same as your 16g they go for 850

 

[kpt4321]

Anything larger than a 16g is generally going to need an external gate, even if you can buy it with an internal. The PTE turbos will probably work with an internal and a cut housing, but a cut housing is a really crappy idea.

 

[Twizzle]

oh? then, i guess ill get an o2 housing, and what wastegate size would be sufficient for a 50trim or agprs52? and waht about the oil lines? im also very confused about the o2 housing. if i needed a flanged one for a wastegate, what does the dump tube do? also, where can i get the cheapest o2 housing w/ flange? this suddenly is turning into a 1000$+ job 380$ for flanged o2, 250$ for wg, and 850 for turbo... this is ridiculous

I just installed my PTE 50 trim, internal gate without the divider cut. I was afraid of creep also. I had a 2g O2 housing ported, but I wasn't satisfied with the port job on the wastegate side.
I used my dremel and a carbide cutter and several other attachments and ported it out even more. I also enlarged the exit arear right in front of the O2 sensor. I then port matched the O2 housing to the gasket and turbo's wastegate area(they were definitely a little off). After that, I polished all areas.
The results are amazing. It held 15-16 rock solid in every gear. Needless to say I've turned it up but that's a good setting to put it to if I ever had to drop the car off at the dealership(alignment, etc).
Good luck

I will agree with both points, each for a different reason. i woudl say that an internal gate is ok on a turbo that large if you plan on just cruising around and having a decently fast car. You will need to port the O2 housing so that you dont creep, but it will work. Now, if you are going to go for a sweet timeslip or some huge pumpgas numbers then I would go external for the absolute best boost control. You dont need an external gate, but it is a better idea if you have the coin to drop.

ok, i will wait for more money for external gate supporting mods. where can i get a flanged o2 now?

I agree but disagree at the same time...
I guess what it boils down to is what do you call a decently fast car, sweet timeslip or huge pumpgas numbers?

I do agree that external is the best for boost control but you don't need it for what I call a fast car.

To ME I think a low 12 sec street car(pump gas) is pretty fast.
Most that I've researched with internal gates(divider cut on the PTE) have been runnning 12.3-11.?(can't remember), most on pump gas. I know of one that's a full weigh 2g with I believe was a 230lbs driver. If I'm wrong, please correct me.

If money is no option, go external.

 

[boostedinaz]

I guess I should have said it a bit different. If you are on a budget and are looking for mid 12's and up then an interal gate would be a good deal. If you are going for better times and have the money then go external.

...ive already made my decision on going external. now it would really help if i can find an o2 housing preflanged for a tial wastegate, OR a shop in nj that can do this to my o2 or exhaust man. please help me!

 

[boostedinaz]

www.victoryperformance.com They have the ones that will stand the test of time. There are a few here that have cheaper items on there car and they say they are great. Most have only had them for less than 6 months so they are not proven. I have a feeling they will crack or leak after some good use, and the ones from VP will not do any of that.

Isn't www.turbotrix.com in NJ they should be ablt to do it, or sell ya one.


Oh and just to play devils advocate. I had a L2R at 20psi that never creeped.

 

[Attack Eagle]

but isn't creep more prevalent the LOWER you try to run your PSI on the turbo, since the wastegate's job is to try and retain that set pressure by diverting flow around the turbo?
maybe I'm old but 20 psi seems pretty high, I wouldn't expect much creep there, but at settings of 12 -18psi you might have seen some creep.

 

[Twizzle]

oh yeh, i forgot about turbotrix, just gotta find out where theyre located now. i know they moved, but their site is old and never updated. ill see how much thatll cost, and if i dont like that price, ill just order from VP. Thanks guys.

edit: one more question before i order, what is better about the external gate WITH dumptube, as opposed to routing back into the exhaust, and does this make any more noise? what makes a dumptube illegal? oh, and im not worried about inspection so i dont need to keep it "legal"

 

[L2RTSiAWD]

If you don't need to worry abuot inspection or emission, go external dump. It's loud and sounds awesome.

Like John said, if you don't need to go to inspection then go external. It is loud but sounds neat. The reason it is illegal is becasue you are letting exhaust out that has not gone through a cat or muffler. Its not so much the muffler as it is the cat, but alot of states have a Db level you have to be under. Just so you know, I dont think you are dumb just a statment, but it will only open under WOT.

I highly recomend a turblar manifold with the tial WG flange off the colector end like a DMP manifold. You want the WG to be before the turbo to work the best.
This is just my oppinoin and what I have read in turbo performance books. What ever you do dont weld a flange on one of the exhaust manifold runners. All you are doing is just reading the pressure off that runnner. You want to read the pressure of the entire exhaust coming out of the engine before the turbo for the WG to operate efficently. The O2 housing would be my next choise.

I believe he was thing about having it come off the O2 hosing.

The other thing I dont like about running a WG off the #1 runner is that it will cause some reversion becasue the gasses from the other runners will have to go back up that runner to exit. :thumbdown
