Bmore410_TSI Posted August 25, 2009 Report Share Posted August 25, 2009 Ok, first off I'm not very mechanically sound so I dont know much. I have everything under the hood running pretty sound. I have a stock '89 Quest that I have been rebuilding and I'm looking to get more power. I'm looking to upgrade to bigger turbo. What are the pro's and con's of upgrading to a bigger turbo? Looking for inexpensive way and easy way to boost power. Link to comment Share on other sites More sharing options...

nathan89quest Posted August 25, 2009 Report Share Posted August 25, 2009 my experience with putting a biger turbo on my quest is increased lag. with a bigger kick in the pants when it comes into boost!! the 16g i had on my quest didnt make good boost (8-12psi) until 3k.

Guest Posted August 25, 2009 Report Share Posted August 25, 2009 For more boost, you need more fuel. You can get the stock turbo to boost a bit more with a manual boost controller. But you're risking going lean with too much boost. But if you're convince with bigger turbo, a 14B turbo from a DSM will be more than sufficient with a stock car.

Bmore410_TSI Posted August 26, 2009 Author Report Share Posted August 26, 2009 How much more performance would I get out of upgrading to a 14B? and what does DSM stand for?

JAinsworth Posted August 26, 2009 Report Share Posted August 26, 2009 How much more performance would I get out of upgrading to a 14B? and what does DSM stand for? 14B isn't a direct bolt-on. A 19c is a good street turbo. Diamond Star Motors Link to comment Share on other sites More sharing options...
intense98rt Posted August 27, 2009 Report Share Posted August 27, 2009 Does the ecu allow for more boost? I just got a quest and it has a bigger secondary injector. When I get around 4k rpms now it feels like its breaking up/losing power. I think its running rich. More boost should lean it out? How much power can a rebuilt stock motor handle?

The Starion/ Conquest came with two stage injectors, a primary and a secondary which is bigger meaning it flows more fuel. What kind of injectors are in the car now? If you're experience a hesitation around 3-4 k you maybe having other issues, like the vaccum advance not working properly. Link to comment Share on other sites More sharing options...
