bimmer boy 21 Report post Posted March 11, 2005 (edited) its a turbo external waste gate (i think) my brother has one Edited March 11, 2005 by bimmer boy Quote Share this post Link to post Share on other sites
bimmer boy 21 Report post Posted March 11, 2005 the waste gate helps by releaseing presure when the throttle is snap shut so the pressure does not bluid up and spin the turbo backwards. And when it is opened the turbo does not have to re spool Quote Share this post Link to post Share on other sites
petone 0 Report post Posted March 11, 2005 (edited) nah, internal wastegate. controls boost pressure. internal is fine for low pressure but ya need an external if you are going to run high boost. what bimmer boy is talking about is the blow off valve, goes off whens the throttle is suddenly shut so the charge of air doesn't go back to the turbo and slow it down, or something along those lines.

bmaguy 0 Report post Posted March 11, 2005 It is not the waste gate, but the waste gate actuator for an internal waste gate. yep that is the actuator that opens the internal waste gate at a set psi. the pipe comeing off that is where you can plum in a boost tap to ajust the psi setingslooks like a ihi type turbo am i right?

slideways 47 Report post Posted March 12, 2005 yup this is the actuator for the wastegate it controls a lever that opens and shuts the wastegate are you thinking of turboing your bimmer? Quote Share this post Link to post Share on other sites

E30-323ti 66 Report post Posted March 13, 2005 I wouldn't bother with a TD04 on a 2.5, way too small!! I posted a link a while back with a 323i with a WRX TD04, and it was stated as being too small, nice & responsive but no topend!! Hell, they come on GSR's & base WRX's!! Even a Nissan T3 off a Rb20det would be getting small on a 2.5!! Quote Share this post Link to post Share on other sites
CaM 0 Report post Posted March 13, 2005 can't go wrong with a garrett T28 from a RB25DET nissan engine... ball bearing as well usually, plenty of flexibility for mods to turbo, fairly priced as well if you look around. Got a TD04 on my van, sure it's a diesel but it runs outta boost around 3k rpm, boosts from 1250 tho haha Quote Share this post Link to post Share on other sites
