Im curious which turbo would be a better choice since the T04B V-trim is $580 and the T04B 57-Trim is on sale for $599 since the 57 trim is a bigger turbo but i was curious if bigger is better in this case im looking for 350 whp anything above that is a bonus which turbo will best match my mods my mods with the turbo will be......

2g Ported manifold
Evo O2 housing
3" downpipe/3" magnaflow cat/3" catback
ACT 2600 with Street Disc
Fidanza Flywheel
Extremeintercoolers.com street FMIC with 2 1/2" pipes
Turbo XS Type RFL
3" Intake with K&N 3" intake Filter
RRE Oil Catch Can
MAFT
3" GM maf
SAFC 1
Walbro 190 lph Fuel Pump
550cc Injectors
BM AFPR
Balance Shaft Removed

I think that the V-trim would suit your needs very well. The V-trim is a great street compressor because it works well at lower boost levels. But I have to say that both are great choices and either would work well with your set up. If you have any more questions feel free to PM me.

I had a 255LPH walboro and an AFPR bumped up in pressure and I still maxed out my 550 injectors around 17psi and they began to cut out and run the motor lean over 20psi (120+% duty cycle @ 50psi base pressure).

I have 650s now and am maxing them out around 25psi but am not going to go over 100% duty cycle on these injectors at that boost level. 25psi is a nice desired pull and if I wanted more, I'd squeeze it out of my AFPR and tuning.

If possible go with 750s or go with an EVO16g if you dont want to upgrade your injectors.

....but yet Dave Hall explicitly posted around here somewhere that the V-trim is "not forgiving."

Even with an EVO3 550cc inj's will not give you 350whp. 650cc inj's are the minimum for the EVO if you plan to us eht e turbo to it's full potential. I had that turbo and 550's and maxed them at 20Psi. Since you are going to need injectors with either of the Bullseye turbo's and those are the only 2 you are considering why not go with the larger? I believe Slow Boy Racing did a dyno test of the V-trim in their on going turbo testing on the dyno. I am not sure of the results but maybe I can find them. Mark

Do an advanced search for holset with the author being sweet97 and read the thread titled :"bullseye turbine: how much power have you made? You will find info on the 57 trim and the V-trim in the thread linked in there also. mark
I don't know how to do a link so you will have to do it the long way! Sorry! mark

Thanks guys great info and I new that someone was gonna mention about the 550cc's and hopefully they will do me at first but I think you guys are right i will have to step up to 750's to see the full potential of this turbo. In my eyes and it looks like some of yours and from what i read the V trim is a great turbo for the 300 - 400 whp range.

About getting an EVO III turbo I had my eyes set on an evo for so long then I started reading about the rave revues for the V trim and there isnt much price difference. The other thing that changed my mind is my intake is 3 inch pipeing and the V trim has a 3 inch inlet so i want to take advantage of that.

Please link to these rave reviews about the V-trim specifically. I am looking for multiple instances since you said "reviews."

Ok that was over exagerated i just meant that i have heard way more good then bad about the performance of the v trim. Alot of people seem to like this turbo especially for the price. A simple search im sure you will find out the same thing.

A bunch of dyno charts, yep, seem them. I should have been more specific: long term reviews of this turbo or have all these people's turbos fallen victim to the surge issues related to the V-trim like 99gstracer had?

I personally used one for about a year, I then sold it OVER a year ago and have NEVER heard anything back from the buyer that the turbo has failed. Do you plan on purchasing one of these turbo's, Because it seems like you're just trying to cause a war in this thread?

hi guys, i dont know much about the v-trim, but i do know about slowboy's turbo testing page. and in that page at 20psi, the evo 3 16g actually made more power then the v-trim. here is the page just look down the list of turbos they have tested thus far. i too was looking for a big turbo, but then you see something like the evo3 16g out performing things like slowboy's own 50 trim and other turbos that should be way out of the league of the evo3 16g. plus i have not seen a turbo yet that might last long and give you the performance of a mitsubishi turbo. except maybe the new holsets because they are built for durability on diesels. plus i read the center shaft on them is hefty. anyway here is the page, draw your own conclusions:

I have any my participation in this thread is done.

Looks like the EVO is the champ so far and at $459. it's the best bang for the buck for sure. If anyone did the search I suggested you would want to get the insurance offered on the 57 trim and matbe the V-trim also. I'm waiting for the Holset test, been waiting a year for a dyo test on one! Mark

There seems to be problems with the Internal Gated Vtrim, and 57 Trim, from reading SBR's reviews.

Externally Gated is the way to go wiht these turbo's.
Comparing a hybrid to a 100% bolt on like the EVOIII isnt fair in the regard that with the vtrim, you have to buy oil feed and return lines, and the hardware for external gate.

so really, they are NO where close in price.

I have a Vtrim and an AGP rs49t Sitting on my desk right now, I am going with the AGP, mainly because its a more known Brand, and its bigger, and the specs offer the same spool times, so why not have more


PIC vtrim Vs. AGP 50trim for size compare

i was not talking so much about the price, but the power. at 20psi the evo3 16g makes more power then both the 57trim and the v-trim. ... and look at this, it smokes them again at 25psi, the evo3 16g was putting out 400ft/lbs of torque. it even does almost as well as sbr's g-50 and the bastard 20g. i too wanted a 50 trim at one time, but why, the evo3 16g takes less mods to have on your car, cost a lottttt less, is very reliable, and it even makes more power. not trying to bash, but the is the reason you are getting one of the other turbos because you want to make power at a higher rpm?

Every car is different. They all respond to mods differently also.

more power at less psi, haha.

The evoIII can make 400whp with an expert tune. this has been discussed in other threads, how many normal guys have acheived this? sure buschur, and sbr can, but look at their rescources.

the vtrim can do the same with a street tune and a novice tuner. look at the sbr test thread. the evoIII STILL crept!!!

http://www.turbochallenge.com/rocky.htm

335 whp at 16 psi

371 whp at 22 psi
394 whp at 24 psi

http://www.turbochallenge.com/manny.htm

402 whp at 25 psi

I think people are failing to mention one important factor in those SBR tests...the fuel they were using...116 octane. So don't expect to get similar numbers on your pump filled street tuned car.

no i remember. they couldnt of made that much power on a evo3 16g on pump without water/alcohol injection. also, what you said would apply to the other turbos that were still making less power on c16.

why is this an expert tune, if you have the right equipment, datalogger, wideband, and anything to control fuel. you could set yours up the way they did. they even tell you that they shoot for the same air/fuel ratio on every turbo, and the same timing. might i add that they said they could have made a lot more power from the evo3 16g if they added timing up top, probably sense the turbo was not flowing as much anymore due to their cams. they are experts, that is for sure, but they told you what they did from the beginning. from what i can tell they were not running on the edge with c16, they could have definately gone a little leaner and added more timing, but for the sake of the test they did not.

, this guy made more power at 16psi then sbr did at 20psi. he says he was tuning conservatively, but he does not tell you how much timing, or the air/fuel ratio. so we cant say much about this except, great job. would like to know how he did it though, out of interest.
not trying to bash, just trying to get a better understanding.

I had the vtrim on my car when they first were introduced by bullseye. In the end i had to return it and upgrade to a 50trim because I like some others experienced the "surge" issues from this turbo especially after 18psi+. Good turbo but was turned off by that surging.
