t04b(v-trim) Bolt on Discussion

[Race94]

so the t04b spools up faster but has less top end, and the t04e spools up slower but has better top end??

Is the difference much??

If you were to run a T04B and an T04E on the same car, the T04B would spool quicker. As long as you were operating in the Hp range of that turbo the difference would be minimal. However, if you operate a turbo at the upper end of its HP range you will find the boost "fall off" at higher rpms. For example, if you plan to operate the turbo between 15-18 psi on pump gas making 300-375 whp then the T04B would be best. This turbo will also support 450+ on race gas at 22+ psi. If you wish to make 350-425 on the street and 500+ at the track then the T04E will do the trick.

my next turbo will also come from these guys


i spoke to david a while ago, man that guy just feed me mountains of information, it was awesome, he just sat there telling me everything i needed to know

i ####ied out and got a 16g, but when i get back from europe, i will be swaping to this t3.04b

another reason for you guys to get this t3/04b is that the compressor housing is about 1" smaller then those GIANT t3/04e and therefore there will be no need to bang water lines or cut your fan to pieces.....just fyi

To run a T04B for the street in pump gas at about 15-18psi will this be enough?

FMIC
550cc or larger?
255lph w/regulator

I plan to run this turbo at 15-18psi, looking for constant low 13's on street tires.

That should work just fine.

1029TSG,

Do you have any turbo that would work well on ~1.5L of displacement? I am checking out what options I have for a turbo upgrade. I'd like 15psi no later than 4500RPMS as this is a pure street car. Thanks.

Would this be a twin turbo setup for your Stealth? If so, we have had a few customers use two of our T04B V-trims. However, you'll have to use a custom TD05 header. I would only recommend this for 5-700 hp applications. You may find more information on the 3si forums. If not, we recommend any of our complete turbos for any 1.5-2.6 liter engine. All of which are available in a T-3 or T-4 inlet as well.

 

[Gabe92RTTT]

I am sorry, I should have been more specific. Yes, I am looking for turbos for my Stealth. It is ready for TD05 type turbos and I was leaning towards Evo III 16gs initially and shooting for ~ 500 AWHP, but am keeping my options open. I am a little in the dark when it comes to T3/T4 turbos however...still trying to learn.

 

[92awddsm]

Well, I just recently switched from a big 16g to a t04b v-trim and the difference was amazing. I did go with a full garrett setup so it is diff from the bolt on style. But it pulls to 8k now when the 16g would start dropping boost at 7k and fall flat by 7200. No boost drop and killer top end. I think it was worth the investment.

If 500hp was your ultimate goal then I would stick with the 16g's. If you want a little better spool up and a larger internal wastegate to eliminate boost creep then swap the turbine housings for our Mitsubishi inlet upgrade housing. If you want some room to grow, say 6-700+ awhp then the T04B's will get you there.

I plan on buying a turbo soon. I was going to go with the e316g... But the fact I have to spend another 250 bucks on an install kit on top of the 550 is a turn off. To make only around 300hp. I am VERY interested in this turbo. I have a few questions...
Is this a total bolton setup? If not, what do I have to do to make it work (Im not a novice at working on cars... Just dsm's).
I have a 2.5inch downpipe, will this hender the turbo too much?
Is it harder to tune as opposed to a 16g? Via SAFC.
Drivetrain going to holdup? What other componants would you upgrade? Besides the obvious fuel, IC, ect. ect.
Thanks.

I know what you mean. Our complete turbos will bolt right up, you will however have to modify your oil feed and drain line. This can easily be done with our kit for $99, it features a -4 steel braided oil feed and drain with all the gaskets and fittings. FP, 550's, SAFC will be good for 15-18 psi. Upgrades like 3 inch DP and FMIC will allow you to run more boost, make more HP and have better spool up.

i read one of the earlier posts where "full spool at 3300" was mentioned. this seems a little hard to believe as my small 16g gets full spool in 3rd around 3300rpms. i'm not calling BS at all, i just want to hear from B-E about when *most* customers get full spool from the v-trim to4B in 3rd gear. i have pretty much maxed out my small 16g (320AWHP) and am ready to move up.....but i'm also a quick spool junky. so, how about some talk on spool-up with a stock compression 2g?

 

[1029TSG]

I have actually heard that from a few customers as well. It is possible to have better spool up with a slightly larger turbo using our conical shaped turbine housing. This design is a true cone shaped entry or inlet, unlike that of the 7cm OEM housing. This accelerates the exhaust gases, thus increasing throttle response allowing the turbo to spool quickly. However, for most customers who have the basic bolt on upgrades usually see 15-18 psi at around 3500.

Sorry to be a little off subject... But did you get my PM?

Sorry, just checked it now. Already received 135 emails this weekend, you guys are keeping me busy.

 

[Race94]

so 550's should do it for the to4b at 15-18psi?
Anyone can confirm this?(actually running it)
Will 15-18psi be good enough for low 13's high 12's??

 

[theNEW]

Theoretically 450's *should* be good enough to get you there. Yet not safe enough, but you should be able to get to low 13's on the stock injectors.

I will be upgrading mine.

I should be getting my fuel pump tonight and I dunno how I am gonna bolt all this up. I think I am just gonna bolt on the t04b this weekend with a 1g bov for now. and add the parts to let you know how this turbo does with the supporting mods.

 

[drk mrk iv]

Tell us how it goes

Im running 550cc's with my t04b. I am currently running 21psi on 93 octane fuel. I also have my base fp set at 48psi.

 

[nazthug]

let me say this

I have a small 16g, with a stock rewired fuel pump and stock base pressure, and i am maxing them out past 20psi

When i swap to the t3/04b i am going to get the 660cc and a 190 fuel pump that will be plenty to do about 24psi on the t3.04b and should be good for about 350whp or so easily, and 350whp is my ultimate goal on the stock block

Damn i wish i got this turbo before...

 

[sweet97]

I have the turbo installed and I do not know if the gate is open when the arm is moved away from the compressor side? In other words if I turn the rod to the the right( clockwise does that open the flapper?) This is with the actuator off. By the way I have the T04e. I have an AGP RS49 which uses the same turbine as the bullseye turbine. Can some verify this for me? please. Mark

Hey Mark, I just got your message and tried to return your call but your line was busy. If you turn the rod clockwise or shorten it, this will increase the boost on your turbocharger. If the rod is lengthened this will decrease your boost. Its best to bypass your boost controller if you have one by hooking up your boost reference from your TB or intake manifold directly to your actuator. Then lengthen or shorten the rod until you reach the lower end of your boost range, say 15 psi. In most cases it will take 3 or 4 turns of spring pressure to acheive this level of boost, so you will have to "stretch" the rod over the lever. Then hook back up your boost controller and as you bleed off your reference this will increase your boost. If you still have any questions, please give me a call.

Just received 12 T04B-H3's from Garrett. Now on sale, prices starting at $649. Bolt on a Full Garrett turbo without denting your waterpipe. This turbo is rated at 49 lbs/min (500whp), same as the 50 trim. www.bullseye-power.com

 

[14.5 drift]

since when does 49lbs min equal 500 whp? Looks like 500 at the crank if you rounding it off. Doesn't every lbs stand for 10 hp at the crank? the t25 flows 27 lbs but i dont see any one with 300 hp to the wheels.
