TDI. 2013 Golf TDI DSG. Jun 19, 2015. #5. UhOh said: Turbo boost actuator rod likely needs adjusting (too). If it's a "new" turbo as he mentioned, then it shouldn't need any adjustments. However, if it's just "another' turbo, that's a whole different storycould be a sticky VNT mechanism. You mention on using a turbo from a 1,6td in your 1,9liter engine. I suggest you drop the idea. The 1,6td unit has a turbine housing of a 0,36 ratio. This will make your 1,9 liter engine perform really well from approxiamately 1000rpm to about 3000rpm. Might be great for heavily congested city traffic tho'. Guidelines for Higher-Boost Applications. To run boost levels from 6 to 10 pounds, Weiand recommends the following: Forged blower pistons with a static compression ratio of 7.5:1. Steel crankshaft. Four-bolt main caps. Steel harmonic dampener. Stainless steel valves. Three angle valve job to promote better cooling. First We Now need more Air so its time for a manul boost contoroler this can be anything form a fish tank bleeder valve, to a full on greddy electronic boost mangement system. personally I like the grainger valve its cheap, works well and is reliable, here is a link to all sorts of boost contorllers boost controllers once again this could be you can, but i would recommend that only with a small turbo such as a VNT-15. with a regular 1.6 turbo, there will be a lot of off boost smoke, but on boost power should be the same as a TD pump if everything is set right. a larger downpipe would help with the turbo lag, but a true TD pump is what you want. And there is not a one-size-fits all thing necessarily. Some folks convert the pump to a mechanical control, usually called "M-TDI". Of course, this also means you have to come up with a different way to control the boost, as the ECU also does that. And you'll have no OBD obviously, which is helpful for tuning. Nov 14, 2012. #10. VeeDubTDI said: I think the turbo could theoretically make 1 - 2 psi at idle if the VNT was in max boost position. However, I doubt it is programmed to do this due to increased NOx production and fuel consumption and no benefit to performance. pvNn9kq.
