M Trim Turbo from Bullseye... worth my money?

[domenico_169]

Hey guys, well im gonna be selling and upgrading my evoIII here asap, and the difference by the time i sell my evo III, and pick up this M trim from bullseye with all the accesories ready to bolt it right up, and shipping, im only looking at like a 300 difference. David at bullseye reccomended this turbo for my setup and says that it flows 44 lbs/min. and is basically like a 20g on rhoids. i was looking for some input on this, and what you guys reccomend. my next mod would be cams... hks or comp, im not sure yet. but it seems for 300 bucks and a little bit of time, this would be a worthwhile mod. he estimated a 50 horsepower gain on the dyno at 20 psi from what i am running now on the evo at 20psi. he also told me that my 550's should withstand 20 psi for now on this turbo. thanks for your input.

Hell yes its worth. I recently got to go to Bullseyes headquarted 3 times in the past 2 weeks. I got to check out all there new lines of turbo's and housings, and all I can say is the quality on this stuff is top notch A++. I would hightly reccomend any bullseye product.

For what it's worth.... I have talked to quite a few people here on tuners that have logs saved showing their EVO III 16g's actually flowing between 42-44lb/min of air.

 

[project_tsi]

Regardless, Id still go w/ the upgrade. Im sure youll gain a few 10th's.

 

[CanadianTSi]

I don't think the gains will be worth the effort.

As stated before you can push your 16g to the low 40's in airflow, so a few more pounds will hardly be noticed.

I would suggest something that flows in the upper 40's as a worth while upgrade.

 

[domenico_169]

what would be my best bang for buck on stock bottom end? i dont wanna go to crazy.

 

[herostar]

I'd suggest something around the size of the 50-trim turbos. I'd look for something that flows around 50lb/min of air.

 

[domenico_169]

i was also thinking about a 50 trim from bullseye... but is this turbo gonna be overkill? or spool up to slow for me?

I ordered this exact turbo to replace the stocker which wasn't working. Should be here tomorrow. Not sure how long before I get the car up and running as I've had a ton of problems with this car. I was going to get a EVO 16G as well but the sales department at bulls-eye said go with this one instead as it outflows the 16G. Just need to get some more supporting mods like fuel/exhaust. Actually I was going to go with another stocker just to get it up and running but couldn't find a cheap one. Hopefully this turbo is good and I also ordered the 24 month no Hassle warranty just in case. Anyone have any more input on this turbo?

On a side note, I've been porting the O2 housing should I as well port the turbo inlet/outlet? I don't have the turbo in hand yet but I was just wondering...and how much should I port this stuff?

Yes, but it is terribly out of it's efficiency range at that point, whereas a larger turbo wouldn't be.....

I would suggest something that flows in the upper 40's as a worth while upgrade.

I agree there. I would suggest a 50-trim.

Second, the bullseye housing strips almost after any use. My friends stripped after 500 miles and taking the turbo off once due to there crappy gaskets that blew up in 44 miles.

I've never heard of their housings stripping out. And if one ever did, I'm 99% sure they'd replace it for free with no hastle. I've had a couple different Bullseye turbos/turbine housings on my car and I've never stripped the housing out. Once, I had a problem with the bolts breaking off, but like I said, they replaced that for free with no problems.

The slow spool associated with the 50-trims is very overrated. Full spool is only ever a downshift away. And a 50-trim is not overkill at all. They are only rated at 49 lbs/min. If you are even going to bother with an upgrade, I'd go with something that flows equally if not more than the 50-trim.

k well ill call him back and ask him more info about a 50 trim. i think ill go with that. what do you guys think my horsepower gains will be if i run 20 psi on it like im running 20 psi right now on the evo. but i am also guessing i will need new injectors cause my 550's wont be enough??

Your HP gains are dependant on your tune, so none of us can accurately answer that for you. I would recommend running 650cc injectors if you really plan to stretch her legs.

PS - I am currently running a Bullseye 50-trim at 22 psi w/ FIC 650's on a stock block and head, and so far, I am very happy with this set-up.

 

[CanadianTSi]

With my evo 3 at 20psi and pump gas I went 12.9 at 110, with all the same mods and my 50 trim at 20psi on pump gas I went 12.5 at 112(I also had a boost leak)...so there's the difference.

so you guys would reccomend this product? what else will i need to get then? just have it internally gated? or will i also need the new oil feed and drain line kit?

 

[green92gsx]

What the hell is a "m" trim? Is this the new biggest thing since the the "super" 50 trim didn't fair well.
Someone please explain...

Every other week bullseye puts out some odd ball compresser wheel combo that doesn't come close to the combos already available to the public.

I saw first hand a g-vr4 evo-16g car put down 380 whp on Buschurs low reading dyno at the shootout. I drove my way to 124 mph with Fp's dry bearing 18g. What else is there to compair?

 

[domenico_169]

so who would you reccomend me to go with for good pricing and a good bolt on turbo to replace my evo?

 

[green92gsx]

I recommend you continue to tune away at your evo 16g since there's still more power to be made. Throwing a biggier turbo on will not be the answer.

 

[domenico_169]

im not gonna bother with it anymore, im ready for bigger.

...David at bullseye reccomended this turbo for my setup and says that it flows 44 lbs/min. and is basically like a 20g on rhoids.

Did you notice rhoids is spelled with an 'h'? It can't be slang for steroids cuz there's no H. Does Bullseye include a free tube of Preparation H with each M trim?

I was looking for some input on this, and what you guys reccomend. my next mod would be cams... hks or comp, im not sure yet. but it seems for 300 bucks and a little bit of time, this would be a worthwhile mod. he estimated a 50 horsepower gain on the dyno at 20 psi from what i am running now on the evo at 20psi. he also told me that my 550's should withstand 20 psi for now on this turbo. thanks for your input.

I'm sorry, but a 50 HP gain at the same boost just sounds like a lot of marketing hype, especially since you're not close to maxing out the EVO 16G. Your power is not limited by the turbo at your current level of mods. Which is why I strongly suggest you get some cams before you upgrade the turbo. With cams you will get a nice jump in power, and it will give you a better idea of how big you want to go with your next turbo. Get either the HKS 264/272 or FP-2. Both are proven, you can't go wrong with either.

 

[domenico_169]

well the reason i wanna do turbo upgrade is because i can sell my turbo for no problem. i am gonna be getting cams very shorty after the turbo upgrade. i am thinking on a 50 trim, what do you guys think?

 

[RavenX]

Slap on the 50trim and call it a day you won't be disappointed. Yes the evo16g will get you to 400whp but a bigger turbo will get you there with less boost. Not to mention those 400 on the evo were probably made with c16 race fuel. Anyway about the bullseye housing i have never had any problems with them stripping and ive taken my turbo down more than i can count. It is true that their turbo inlet gasket sucks but oh well they can't be perfect now can they. I had the vtrim turbo and after battling with a surge problem i upgraded to their to4b 50trim for $200 and i can say i am very pleased with this turbo. Pulls hard at only 19psi with the tires spinning in 2nd all the way. Ive yet to get any dyno time so we'll see what race gas and 28psi does

 

[99gst_racer]

It is true that their turbo inlet gasket sucks

Not anymore. Bullseye now offers that 1/8" thick stainless steel plates like SBR and RRE offer. They also have the stainless gasket for the turbine-to-O2 housing. But I do agree with you that their original gaskets did suck.

 

[domenico_169]

anyone have any pics of one installed? i am running the evo now with custom made fmic piping. i just wanna know how my intercooler piping is gonna have to change for this thing now, and if its gonna be a headache. so i guess i am gonna go with the bullseye 50 trim, unless i get a real good reason to object. thanks for all the input.
