    Hello I have a question. I have an 1985 Cadillac Fleetwood brougham with the 4.1 liter HT-4100 V8. Is it possible to supercharge or turbo the engine? I haven’t seen any kits available for it. Thank you.
  2. 2008-2013 CTS Performance Mods

I would definitely be going through the engine are refreshing the bearings, checking tolerances etc. I would also like to add a cam to the motor and possibly some pistons and such to...

  4. ATS General Discussion Forum
    Had a small fire between the turbo and the firewall. The fire charred a few things, but I'm unable to identify a badly burnt connector that I'm sure will need replacing. Any help or photos would help a great deal. Engine also throwing a P0171 engine code which I imagine has to do with the...

  9. 2004-2007 CTS-V General Discussion
    The car is a 2007 w/ about 80k on it. It has failed (then passed) emissions twice in the last year of it changing hands (one dealer to another. car is 1-owner). Heard and ignored parade clunk (thanks iphone and cadillac forums on the fly!). I imagine its a result of the monster under the...

    If you can believe this link, in 2013 the SRX will get an updated grille and the 3.6-liter, direct-injection V-6 engine currently used in the Chevrolet Camaro. Sube

    Just noticed the new 2011 Mercedes-Benz S63 AMG(sedan) is sporting a new 5.5 liter bi-turbo V-8 that is available with either 544 HP & 590 ft-lb of torque OR 571 HP & 664 ft-lb of torque! Sounds like it could spell trouble for the unmodded V's out there?

  14. Northstar Engines and System Technical Discussion
    About three years ago, my '97 STS would set the PC 0741 code - I'd clear it and it wouldn't re-set for almost a year so I never paid much attention to it until recently. It began to set the code every couple of days. There are no other PCM codes stored. The symptoms I've noticed are: No RPM...

  16. 2009-2015 CTS-V Performance Mods
    Looking to upgrade my 09's exhaust. While I'm at it "thinking" adding headers and modified (sufficient enough to get me thru inspection) cats too. There's a lower pulley upgrade in the future. :yup: Knowing the Corsa's have low drone technology, having used a set on my 03 C5 Coupe, at idle I...
