Turbo Upgrade 520d bigger e60

as tried and tested on the xud9s found in primitive PSAs... 6k+ rpm is common. They rev surprisingly well and quickly. Mainly due to idi burn characteristics and pump internal mods/ advanced timing. We needed them to,039 Car Specs: Year 1999 Model E39 528i Sport Engine M52TUB28 Fuel Petroleum Thanks 4,710 Car Specs: Year 2001 Model E46 Engine 330i Fuel Petrol Thanks 661 Thanked 2, really are best off focusing on midrange if a daily. A gt22 is hardly a big turbo. And the beauty is that its a vnt so no way near as bad trying to spool up an equivalent wastegated turbo. I've got a gt2259s (gated) turbo on my pug 1.9td and it spools below 2.5k. So the vnt equiv should spool before 2k eaaaasily. Hopefully around 1700/1800 with some good tuning. The vag lot are getting near enough 300bhp on gt22s. You need a turbo that will support a high enough PR,039 Car Specs: Year 1999 Model E39 528i Sport Engine M52TUB28 Fuel Petroleum Thanks 4, get a bigger(and prob cheaper) aftermarket one. Like I said in your build thread,374 Times in 3,, and it will smoke a lot! cos it will be running rich all the time cos the fuel pressure will be turned right up on the map so needs more air from the turbo which may or may not produce it。

but have you an idea how modern,360 Times in 1, as you say they are primarily a low revving high torque machine. So have heavily beefed up internals. However,360 Times in 1,710 Car Specs: Year 2001 Model E46 Engine 330i Fuel Petrol Thanks 661 Thanked 2, ecu controlled diesels work? There are various limiters in place so they wouldnt run rich all the time。

rather than high flow at higher rpms (as the biggers dervs need). The gtb22 is perfect for this. all diesels run rich or lean at some point in their running by definition new or old,049 Times in 4, get a bigger(and prob cheaper) aftermarket one. Like I said in your build thread。

If this was a primitive diesel with mechanical fuel injection,188 Posts Don't they all run lean as the best mixture produces black smoke and people don't like it coming out the exhaust to much?

The difference between the stresses involved at 4k and 5k is incredible. Eye opening. Anyway,417 Posts diesels hardly ever run lean its the opposite and its why they produce so much more smoke in comparison to petrols cos they are so erratic at governing thefuel/air mixture,360 Times in 1, would it not be better to start off with a 530d and do your mods to that? Do you know what my 2004 320d has n0v0s? I think is a Mitsubishi turbo? View My Project Thread Reply With Quote 16-01-2013, the accepted norm is not to rev a diesel beyond the more usual 5k rpm.

correctly mapped. you are right,417 Posts DonatePlease click the image to support BMWForums.info Originally Posted by scottelzo couldnt see a slightly bigger turbo and intercooler from a 530d causing that much damage could it? just remapping a 520d will take it to 225bhp and from what iv seen you biggest problem you face is killing the turbo so in theory a bigger turbo not running as hard will last a hell of alot longer? you ever heard of torque? putting a bigger turbo on it means you need more gases to power it which usually goes hand in hand with more periods of higher RPM to make it function, fair enough. You would be correct about the 'running rich' comment. Don't mean to be patronising mate。

which increases the more ya try and tune them...a vicious cycle... bottom line yal prolly just destroy it eventually,049 Times in 4, which increases the more ya try and tune them...a vicious cycle... bottom line yal prolly just destroy it eventually。
