zim Posted August 27, 2016 Share Posted August 27, 2016 Evening, My cousin currently has an S3 which he fancies a 200 tdi in it. He's been speaking to a company that have recommended putting a 200 engine in, but removing the turbo. Do any of you on here have any opinions on this ? Thanks Gordon 1 Quote Link to comment Share on other sites More sharing options...
Jon White Posted August 27, 2016 Share Posted August 27, 2016 Yes. Fit it with the turbo. I have never understood why people insist on taking it off. The plumbing really isn't that difficult. 1 Quote Link to comment Share on other sites More sharing options...
Davo Posted August 28, 2016 Share Posted August 28, 2016 I think it was to sort of "de-rate" it to save the gearbox. But I suppose gentle driving would be the key. Quote Link to comment Share on other sites More sharing options...

I've never understood removing the turbo, especially as there are plenty of Series Landys running V8's out there. Quote Link to comment Share on other sites More sharing options...
ejparrott Posted August 28, 2016 Share Posted August 28, 2016 Yeah, fit it with the turbo, or don't bother fitting a TDi Quote Link to comment Share on other sites More sharing options...
Snagger Posted August 28, 2016 Share Posted August 28, 2016 Fitting a Discovery 200Tdi to a 109 is a problem because of the turbo fouling the chassis, so I can see why people do it in that case. Removing the turbo saves the need for the intercooler and oil cooler, so you can just use the original rad and that in turn saves messing about with the front panel and arranging mountings and plumbing. It does however create extra work on the exhaust side. I wouldn't criticise either choice as both have their merits, and it is very much down to the owner and use as to which is most appropriate. All that said, I wouldn't bother with the transplant unless retaining the turbo - far easier to fir a 12J or gas a 2.5 petrol otherwise. DOn't forget that commercial bodied diesel vehicles are clobbered with Emission Zone charges these days, as well as road tax, where as petrol vehicles don't pay EZ charges and dual fuel vehicles pay less road tax (unless already over 40 years age, in which case being classed as "historic" precludes road tax and I think EZ charges too).

Tim2809 Posted August 28, 2016 Share Posted August 28, 2016 Fit a 300 tdi turbo and is a lot easier for routing exhaust Quote Link to comment Share on other sites More sharing options...
ejparrott Posted August 29, 2016 Share Posted August 29, 2016 200 Disco block, 300 turbo and manifold, perfect combination for a Series 1 Quote Link to comment Share on other sites More sharing options...
