pureboiracer 0 Report post Posted May 20, 2007 thinking about twin turboing my 325i was wondering what it involves as aposed to single turbo? Quote Share this post Link to post Share on other sites
Mike 1 Report post Posted May 20, 2007 Um, 2 turbos and associated plumbing? More complex, more expensive and more sh*t to go wrong. IMO get a properly sized single turbo Quote Share this post Link to post Share on other sites

Andrew 30 Report post Posted May 21, 2007 I can't see the point in doing it really. Go single Quote Share this post Link to post Share on other sites

Old_Skool_Bmw 0 Report post Posted May 22, 2007 Would seem a lot harder to fit 2 small turbo's in. have you looked at a big single turbo conversion?? laurence. Quote Share this post Link to post Share on other sites
Assault 3 Report post Posted May 23, 2007 There is no real point in doing it on an inline engine. V or W or flat/horizontal formations can have benefits from a twin turbo set up obviously because of their layout (cylinder heads on both sides of the engine bay) unless you want to get technical and go sequential, which I dont recommend really. The single turbo will be alot better in terms of fitment and if sized right will perform just as good if not better than a twin setup. Quote Share this post Link to post Share on other sites
beema 0 Report post Posted May 21, 2008 yer id suggest big single conversion less trouble, bore it out massive turbo, so it wont put stress on the engine and you'r sweet! Quote Share this post Link to post Share on other sites

User Name 19 Report post Posted May 22, 2008 I agree with the rest of them a Single Turbo is the best bet alot less cash and modification, and if you can someone that will do the piping cheap cause ive being quoted around $1000 for piping off the turbo to the exhaust Quote Share this post Link to post Share on other sites

A waste pipe would be around $60 materials (flange and doughnut), and I'm sure I built mine in an afternoon lying on my back with only basic tools. Proper shop with hoist etc should be able to knock one out in a few hours no sweat. Quote Share this post Link to post Share on other sites
User Name 19 Report post Posted May 22, 2008 Yea i think your right its abit over the top but thats why im not going to fawk out that hopefully my friend when i get my turbo will be able to do custom exhaust extractors, intake and down piping for just materials and abit of cash on top, hopefully i can get the turbo or ecu in the next few months...
