nope didn't stuff anything in there and checked everything nothing was in there when i put it on the manifold, could there be a chance that the turbo is defective somehow. ordered it from ********** if theres any questions of where it was bought from

im heading that way but still my question is why would my bov be way different as soon as i swapped turbos? wouldn't it be just s loud even though my compression could be messed up? all i know is that i did a leak down test and nothing leaking lol. im heading to the compression test but i got a spare motor that i am gonna forge but in the mean while i wanna make sure i didn't get a defective turbo by some odd chance.
This may not be your problem. I had bought a gt28rs from a forum member here and when I put it on I noticed a much laggier boost build. I accredited it to the larger turbo. I wouldnt get 7psi until about 4.5 -5k. I tore down the mani/turbo and my wastegate wasnt seating, the actuator flapper was just jiggling in the wind. I tightened it. Now, OMFG this thing rocks. No traction for me in 1st or 2nd if I punch it. I do have crappy tires though.

see,if you brought this up here(building 4 spi@4.5+ RPM)
we could have told you right away,this is not the case here.
he is building boost at the right time it seems,if I had to say at this point,I would be searching for a boost leak.
can you get a smoke test done?
if you have a party somke machine at home,you can do it yourself.

smoke test? never heard that one but i am learning everytime. i'll double check again tomorrow on the way to work and see at what rpms i hit 10 psi. one thing also i can't figure out is i had mazda do a leak down test cuz i was burnin oil like 1 qt every 5-6 days thats why they did a leak down test. came up fine and they also said my seals and stuff where fine. i also want to know if i go about 2-3 miles down hill and i use 3rd gear to hold back so a bit easier on the brakes, i start to blow some mean smoke out of my exhaust. its like i got a james bond kinda car i can cloud out atleast 5 cars behind me lol. if i go to 4th gear it doesn't do it and i wear my brakes quite a bit.
This is EXACTLY how my car built boost when my wastegate flapper was just flapping inside the exhaust housing. You may want to check that. Here is what I did. Get a long screwdriver and just "tap" the actuator arm with the end of it. If you should hear a vibration type jiggle'n sound then it's moving around and SHOULD NOT BE. I actually have a video of that somewhere let me find it.mdl247 said:

When you open the gate Manually.. With your hand. Is it easy to open and further is it closing fully. (Seating The Flap)

dunno how it supposed to feel when i pull it open manually but it feels a bit easy and the last i remembered it sealed good from the looks of it. but that was before i even put the turbo on the manifold. isn't there a way to tighten the wg without taking the whole mani and turbo off?
