Bullseye Turbine housing with 38mm wastegate.

[WHITE GST]

I would like to know what do you guys think about it, i don't know if i should send my to SBR to get it ported and put the 34mm flapper mode, or buy one from bullseye performance. any input would be appresiated.

I'm not sure what you are asking. What turbo? Are you experiencing boost creep? I have an AGP 50 trim which I believe uses a bullseye turbine and the 38MM flapper.i do not experience creep. Mark

The Bullseye Power Turbine housing is much better than a ported mitsu unit. Checkout the pic of the inlet.

WHITE GST If your uestion is what turbine to use, well what compressor will you be using? I have a bullseye housing. Ilike very much, quick spool and it's BEEFY. mark

I have the Bullseye Turbine Housing for my 14b. It's great. Slows down the spool and adds quite a bit of top end. Perfect for a GST. Plus no boost creep, and you'll never EVER have to replace it because it can be used on pretty much any turbo.

Can you quantify at all how much it slows down spool? I'm contemplating getting one for an 18G and don't really want slower spool.

 

[GinNBoost]

Maybe like 200 or 300 RPM, I'm not exactly sure, but it sure as hell doesn't spool as fast as the T25 did, so at least I can give it a LITTLE gas in first gear...It's a good investment I think. Plus when people look in your hood and see that diesel ass housing, it might scare them a bit if they're comtemplating whether to run you or not.

I have a big 16g, that i bought from Dark Side Racing, i didn't get it ported or anything so i put it on my car them the boost was incontrolable, i searched around and found out it was boost creep also that if i wanted to get rid of it i had port the turbine and o2 housing, so i took them off and ported them, put everything back and took the car for a ride, but it didn't work. i think my only choice is to buy a bigger housing or go external wich i don't really want.

 

[sweet97]

I don't think I spool much slower than my EVO 16g and the 1G is slower than the EVO so you should be fine. What is the cost of the turbine housing?
White GST remove the turbine and cut a notch between the wastegate and turbine outlet as shown on some of the precision turbo's. I have no problem with mine and I just cut a 1/2" x 1/2" notch. Mark

Okay guys! I unhooked the actuator from the flapper door and i wired the flapper door open all the way, and went for a spin, the boost still go up as before but real slow. so the actuator is not the problem, the only thing that could be is that the waste passage is not big enough, because with the wastegate door open i shoundn't get any boost at list not that hi,,,,, I can control the boost alittle bit by putting the silencer in the tip of the muffler, boost gets down about 3psi.

The price for the one from Bullseye Performance is $220.00, thats for the 38mm one. And if i send my turbine housing to SlowBoy Racing is like $60.00 for upgrading it to a 34mm. that includes porting too i belive. So which way should i go? If the 34mm eliminates the boost creep i reater go with it, it's alot cheaper than the 38mm one.

If it were me, I would pay the extra and go for the bullseye turbine housing. I say this because I've seen some cases where the 34mm flapper door didn't help at ALL, and other times it works wonders. However, as these guys have been telling you, the bullseye turbine housing is a wonderful product for solving creep issues once and for all! A local here is running one, and he gets NO CREEP whatsoever.
