Pte 5031RLE, 3431RLE, GT3076RLE?

[DGajre777]

To add on to what ^^^said.

I don't know what you think about bullseye and SBR but here's one choice -
http://www.slowboyracing.com/more.php?id=5463&

It is a 3076R center and has a anti-surge port compressor cover.

Here is part of the PM I got from SBR -
"Bullseye's turbine housing is a .58 to .63 A/R Turbine Housing depending on what turbine wheel you put it in, i'm not totally sure which one it would be with a GT30R turbine wheel, but it's right around there."

 

[andymoraitis]

Yup, I've talked to Jon Nye about the Bullseye housings and he confirmed somewhere between .60 and .63 A/R so that's about right. I don't think they really choke top end flow unless you're revving to the moon. I see no falloff from mine despite the fact that at my boost level and airflow I'm already way off the map.

Daren: Just for kicks, why not look at something like the PTE SCM series? They make some nice power at reasonable prices. The 4427 and 4431 would be right up your alley.

I hope that confuses you even more! (j/K)

Andy, so your using the Bullseye bolt on housing on your setup? As for the SCM turbos from PTE, they seem to be hit & miss (maybe thats just a bad wrap from when they had the 270 deg thrust bearing) but either way, I don't want a std bearing center section, its gotta be BB , want the quick response between gears & the quicker spool is defently a plus so I can run a larger turbo that will spool the same as a smaller one. I guess Im like most, want the quick response of a small turbo with the pump power potential of a large turbo.

 

[daren_p]

So is the above posted turbo from DGajre777 & these all the same except they use the different turbine housings (other then Bullseye & SBR shown with ported S cover & PTE shown with E)?

http://www.slowboyracing.com/more.php?id=2272&
http://www.slowboyracing.com/more.php?id=2397&

The SBR would be the .48 housing, correct & this is the same A/R housing they use on their GT turbo's or can you select your AR?

A GT30(71R) and GT3076 are 2 different CHRAs. The GT3076R is an upgrade turbocharger for the older GT3071R. (Someone correct me if I'm wrong!). Different companies (like PTE/SBR/Bullseye) sell different turbine housings with different A/Rs.

The picture above is a port shroud cover but for the 30R. It is a TO4E but it has a 4" inlet like the TO4S compressor cover but since it has a 2" outlet most people call it a "port shrouded TO4E compressor cover".

I have been told by SBR (SlowboyCSE-Cragger) that the "port shrouded TO4E compressor cover" was designed around the GT 3076R because of it's quick spool tendencies vs. surge line distance on the map.

^^^ I thought all the links I posted were of the 3076, I do know about the 3071 & have seen the maps for it as well. How could you tell that some of the posted links were the 3071 as I didn't see comp wheel specs, they were all just listed as the GT30R.

I didn't realise you could get the E cover with the port shroud, I thought that was only an option with the S cover. Do all the suppliers (SBR, PTE, Bullseye) offer the port shrouded cover for the 3076?

I know PTE has the option of different AR housings, but what about SBR do they offer larger then the .48? & Bullseye just offers one size, correct?

 

[LRS95TSI]

after looking on extreme's website, i was unaware that the fp3052 is cheaper then the garrett 3076...seems to me that the 3052 is better? could be wrong, or it could be that im on fp's design's nuts!

If it doesn't state 3076 somewhere, I assume it is a 3071 (unless proven otherwise), but that's me.

As for the port shroud S cover, bullseye and SBR sells them, I don't think PTE makes one which is why they have the S cover.

About A/R housing, yes bullseye has 1 size PTE offers different COMPRESSOR size A/Rs not TURBINE size A/Rs. I would say if you want the GT30 and 0.48 A/R turbine housing, go with PTE3076RLE. If you want the GT30 and a bigger (0.60ish) and E port shroud cover go with the Bulleye turbo. You might need to contact SBR to get specs on their turbos.

It is not just the cost of the turbo. With the FP turbos you have to add their o2 housings and an o2 mounted external gate which increases the cost.

yea i realize that but most people now seem to be going ext with these size turbo's and i have seen a huge increase in vband exhaust setups....so no matter what your looking at additional costs for both turbos...including oil return lines.

 

[DGajre777]

That is true, it is almost the same if one goes the external gate route. FPs o2 housing is $250 and 44mm external gate is $360 + exhaust manifold (if one doesn't want the 2G), compared to $ 500 for the SBR exhaust manifold + 38mm gate + an o2 housing for it and it ends up being the same cost. The only difference in cost (cheaper) is if one gets one of these other turbos and goes the internal wastegate route since you can't run the FP 30xx turbo with an internal gate.

 

[PSI NRG]

Have you looked in to a gt28? Its a little smaller then the gt30 alot of sr20 guys use them cause the spool is quick but make pretty good hp Ive heard people making 400 hp on those turbos. I'm not sure how much boost it required but maybe something to look into.

the way i look at it is, if your gonna spend the money on the turbo, dont cheap out on the surrounding parts...do it all right the first time and maximize ## spendings...i hope to upgrade, never look back, and never have to upgrade...i think i'm looking at either the full garrett t3 3076 with a dnp mani with tial wastegate and vband parts, or the 3052 and tubular mani....either way, when i do upgrade i plan to make the setup efficient, easy to work with, and it's going to bling like a setup should!

If you want the GT30 and a bigger (0.60ish) and E port shroud cover go with the Bulleye turbo. You might need to contact SBR to get specs on their turbos.

From what I have found out, PTE does have the E, S & S ported comp covers. I know they offer all 3 for their bolt on GT35R I'm just verifying what they offer for the 30R. As for the turbine housing, PTE does offer different sizes. Dejontool lists the .48 AR housing on their website, which I don't want. If I do go the 3076, I defently want the larger .63 turbine housing which I was told they do sell from Dejon. I believe SBR only offers a smaller .48 turbine housing.

As for the FP 3052 being better, to my knowledge they are the same turbo, the only difference is their custom SS casted turbine housing, which also has a larger AR .7 something (which you can't really compare anyways as one turbine housings design specs can be completely different so comparing one campanies AR turbine specs to another could be pointless). Does anyone know if the 3052 uses the E or S surge ported comp cover? I looked hard at the 3052 but like was said they still cost a good amount extra by the time you add in the 44 Tial gate which is almost double a 38 mm gate, their custom O2 housing that I would either need to get modified becasue I need the external recircualted or shell out the $625 that they apparently want for the recirculated housing show on the 3052 web page.

I think I may just stick to internal for the time being & go external later on when I know exactly what I want to do with my setup. When you compare the prices of these two setups their is a good amount of difference.

Just quickly added up the parts for the 3052 & including just the std O2 housing not recirculated, with shipping taxes etc. & being Im in Canada, it would run me about $2750 not including oil supply & return lines & water lines if the stockers wont fit, so I can easily see spend $3K. Now a couple years ago Id so, oh well its only money but now I don't think I can justify sepnding that much on just a turbo. I must be getting old as I'd rater spend my money saving for real estate that usually makes you money after you hold onto it for a while, which is the complete opposite of this money pit I drive around for 6 months of the year

As for the GT28, took a quick look at some of the maps & they look to be abit on the small side. Probably a great turbo if I wanted to run low 20's but one race gas or if I want some room to expand in the future I think I would max it out.

 

[nikkeebabee]

last I knew there wasnt a huge difference betweent he bolt on housing minus the fps since they make their own...

you can jam different wheels in their but the housing will only flow soo much before it decides to choke....

 

[kozluv]

I have had the 3076R on my GSX for about a little over a year now and can give you my impressions. If does not spool near as quick as a 50 trim or your current setup but I like the fact that it hits a lot harder, on the top end.

I see full spool a blink under 4k and that is on pump at 21 psi with 272's and a VSR. Bef-before I "wrecked" my 7 bolt, spool was still the same, it just didn't wind out as quick, obviously with different supporint mods. If I mash first gear, as soon as it hits 4K, in a blink its at 8K and I'm shifting.

I have used a MBC and now the EMS boost solenoid and spool was always right at 4K. As with any larger turbo, you do sacrifice some low end pull if you are in the wrong gear, it can be brutal sometimes, but I don't mind it for what the turbo offers on the top end.

Even in daily driving, granny shifting at 3K is enought to move her along with no problems, and keep up with the flow of traffic.

For FWD it might be a little tricky, even if the roads are a little wet, the tires can't hold until the middle of 3rd in my GSX. If its dry, no problem at all for AWD, obviously, you might have some issues on the other hand.

I looked at starting with a T-28 or EVO-III but knew they would never be what I wanted so I just went big right away. The turbo made 370 whp on pump at a bit over 500 at 30psi on C16, which is pretty much all she can do.

Here was my pump dyno with a MBC, you can see the VSR loves the top end:

3076R on pump

I have yet drive with C16 in her (snow tires+30 psi = ) but even on pump people are still are surprised when I take them for a ride, and it still manages to put a smile on my face.

Hope this gives you a little more insight...

 

[andymoraitis]

Kozluv,

Do you have a compressor map for the 3076? Based on the results you're seeing the turbo sounds like it would be a blast on a stroker but I'd love to see a map to ensure that I'm not already off of it.

Thanks,

Andy

 

[daren_p]

Andy, if you look on the first page of this thread, there is a comp map for the 3076 posted. Its also posted on Garretts webpage but the expand window feature doesn't work properly so you wont be able to see much of the map,. extremepsi also had it listed on their site, think it was under garrett turbo section.

kozluv, thats for the input, that dyno run what kind of boost were you running on pump? Do you have any surge issues and what are the specs of your turbo? (bolt on mitsu turbine housing, T3 housing?, which size turbine housing AR & what compressor cover?)

As far as spool goes don't mind & actually didn't want something that would spool as quick as my evoIII, was thinking the 5031RLE would put me right around 3800 rpms, which would be perfectly fine with me. Didn't want to get over the 4000 mark but depending on your turbo specs the 3076 may be right where I want it to be.

Edit: Wow, just looked at your dyno graph, that pump run was only done at 19-19.5 psi, looks like a pretty nice pull to me.

 

[fwdeclipse]

Daren it seems you are really afraid of a turbo that is gonna spool slow.I upgraded from an evo3 as well.I was gonna go 50trim but did not wanna get tired of it so soon.So I was able to get a good deal on a t4 60trim and as it does not spool fast its well worth the top end for that little later spool times.Remember boost is only a downshift away.

Im not afraid of some lag I just want to keep it to 4000 rpms. Reason being I will be keeping the stock redline & while I know spool up isn't an issue while racing this is a daily driver taken to work every day. Yes spool is only a downshift away but sometimes with traffic etc I just can't be bothered if I have to down shift everytime I need to speed up a little bit to pass etc. Sometime you just want to hit the gas abit at the lower rpms & still move abit. Just don't want the car to be a real "dog" in the bottom end.

Now I've heard that PTE doesn't offer the 3076 with the mitsu bolt one .63 AR turbine housing, just the .48 but the do offer the surge ported E cover. I don't know why exactly they would do this as the .63 housing is std on the 5031's etc, which is a smaller turbo, doesn't make sense to me. Do you think even in the smaller .48 AR turbine housing the 3076 will produce more top end flow?, since it has a slightly larger comp wheel & the turbine wheel is supposed to flow better?

My thinking is maybe get the 3076 with the .48 bolt on housing & internal WG run that for a year & then next year upgrade to an external WG & switch to a T3 5 bolt hotside (which I believe they offer one that will bolt right up to the 3076 center section?), that I can select which AR I want to go with. Does anyone know where you can get a good deal on the Turbonetics cast mani as they all seem to want $430+ for it, or are there any other/better cast mani options out the for a T3?

 

[brute]

Look on the classifieds for that manifold. Another option is buying something like SBR's cast manifold then getting an adapter plate. As far as T3 turbine sides and different lbs/min compressor flow, AGP has a LOT of options.

Edit: Wow, just looked at your dyno graph, that pump run was only done at 19-19.5 psi, looks like a pretty nice pull to me.

I originally had the .48 and it was switched out in favor of the .63, and it is externally gated, dumping to the atmosphere. I have a t3/t4 adaptor plate on the stock exhaust manifold. I have some surge issues, but only one the highway in 5th gear and at a relatively lower RPM.

As far as daily driving it has been great.

For spool comparisons, I do have a built 6-bolt, no balance shafts, and 1mm oversized valves on the head, as well as the bad ass VSR.

I have the dyno on my hard drive if you know someone that wants to host it.

Yes, I thought about using the adapter plate and getting a mount for an external welded to my manifold. I do already have a SBR mani, the version before the current one thats cast for an external, which I wasn't to impressed with as first time I looked at it, 6 months after I installed it the were 2 external cracks about 1" long in the collector. It hadn't even started to rust yet. Haven't had the turbo off since so not sure what the inside looks like, the whole reason for replacing my 2g mani was because it had an internal crack in the collector area.

kozluv did it surge equally with both sized exhaust mani's or was there a difference? Also was there a noticeable jump in power or spool etc. between the two?

Edit: Was also wondering if I did opt for the T3 setup does it matter if I went with the 4 bolt or 5 bolt flange? I read somewhere on here that the 4 bolt didn't fit (not sure if this was just with the turbonetics manifold or not) but when I looked at the housings, they basically looked the same except the 5 bolt has a hole for a wastgate or is the housing itself physically placed different in referance to the inlet mounting flange on the turbine housing?

 

[daren_p]

I was thinking if I do go with the Mitsu bolt on route, the Bullseye power housing may be the way to go. I have to confirm but I believe PTE only offers the bolt on housing in a .48 AR, while the bullseye is ~.55. I would assume the bullseye has more power potential. What do the PTE housings look like internally, are they a copy of the non symetrical mitsu design or they more like a greddy housing, like the Bullseye is? Either way if I change my mind about the turbine housing in the future, I should just be able to swap out either turbine housings with a T3 from any manufacturer?

Anyone running the Bullseye housing, whats your thoughts on it?

Slowboy.com and TurboTime.us both have the PTE DBB 50trim with the .63 A/R Mitsu Bolt On Turbine Housing
